2. Description of the Related Art Conventionally, when treating a fluid, a treatment with a catalyst, an oxidant or other chemicals, an adsorbent, etc., a biochemical contact device, an aeration device, a filtration device, a deodorization device, or a contact device. The standard heat exchangers were used, and it was thought that there was little room for improvement. Small capacities, temporary ones and simplifications were usually inefficient, and overall costs were generally high. Purification of environmental equipment, industrial effluent, domestic effluent, which is not a production process,
Low cost to separate or purify waste, sludge, dredged mud, water containing harmful substances and dust from sediment treatment, gas purification,
There was no simple treatment method. Odor, earth and sand containing harmful components,
It was usual to treat sludge etc. by incineration and cement solidification. In addition, it is difficult to separate impurities, and most of them use the mold of the equipment used in the chemical industry as it is, which is expensive, and even if it is processed, the final disposal cost of the processed object is not always low, Moreover, when wastewater, exhaust, and waste are generated by the treatment, extra equipment costs,
Power costs, operating costs, etc. are often involved, and it was often not suitable for large-scale implementation. In recent years, water pollution and the shortage of suitable landfills for waste have become serious social problems, and the accidents in which harmful substances contained in the buried materials contaminate groundwater without proper treatment have surfaced. Due to the increase in costs, both large-scale processing and small-scale processing are easy, and there is a demand for processing technology with sufficient weight reduction and environmental consideration. On the other hand, a technique for purifying soil contaminated with chemical substances is also required, but extraction or removal or decomposition of harmful substances by it has been a problem. Heretofore, there has been no flexible technology that satisfies such requirements.

[0003]

The present invention is an industrial process,

The problems in these processes are clogging by particles, its removal method,
In order to save material, reduce weight, etc., if a large contact area and a large filtration area are used to increase the processing capacity, the supporting structure and the sealing structure, which increase proportionally, can be simplified. Once the problem is solved, it is possible to improve the chemical, biochemical, and chemical engineering of conventional processes, and rivers, ponds, water tanks, lakes,
Fluids, water, sewage, seawater, mud, etc. generated from the purification of harbors, dredged soil, sludge, hydrated earth and sand, general waste, raw waste, wastewater treatment, sludge containing harmful substances, etc. Allow processing. Moreover, although it involves separation of occlusive fine particles, which has been difficult in the past, it is suitable for purification by dehydration, deodorization, removal of harmful substances, etc., and facilitates recycling and the like.
The device of the present invention alone or in combination with conventional techniques,
It can be used for simple operation, small size, high efficiency, low power consumption, low fuel consumption, and utilization of unused resources and materials which were expensive due to environmental measures. It would also be advantageous to be able to provide a heat recovery, deodorization, purification or filtration device that is simple or disposable for industrial, public or household use and preferably uses recycled materials.

[0004]

According to the present invention, the fluid to be treated can be in the gas or liquid phase, single or multiphase, and can contain solid particles, bubbles, droplets, dissolved components. Fold or squeeze a large area filtration or indirect or direct contact processing function of thin plate or film, paper, cloth, net in a unit volume, narrow installation space or area to make a rope or rod shape,
The processing unit is reduced in size, and the structure and material of the processing device such as connection of the processing unit is reduced in weight and cost, and the assembly, disassembly,
Facilitate repair, replacement, refurbishment, and disposal. In this way, a fluid processing apparatus having a structure in which lightweight thin plates and the like are overlaid and deformed and having a large-area processing surface is configured. By combining it with a functional material for processing, multi-functional processing can be performed. The solution, function and advantage described in Japanese Patent Application No. 4-157258 (fluid processing method and device) in the previous proposal proposes the case where the flow path is flat, but the present invention is mainly based on the thin plate. , Etc., but using a flexible thin plate as a partition wall or a processing wall, and locally or continuously by squeezing, folding, winding, twisting, twisting, bundling, or by a combination process. It forms a fluid passage with an outlet or an inlet to form a processing part, and the appearance of the unit is rod-shaped or its assembly, and the outside is, if necessary, further thin plate-shaped, wound with tape-shaped reinforcing material, and perforated. It is easy to reinforce with a jacket, cloth, net, winding, etc. It is possible to omit the flow path support structure,
Facilitates assembly and miniaturization.

[0005]

[Constituent material and structure of the device] Partition wall, contact wall, cloth, paper, filling material which may be elastic body, gas permeable or diffusive membrane, porous membrane one or more laminated thin plates, substantially from passages Selected from flexible or flexible plastic sheet or film, rubber film, cloth, paper, metal foil, which prevents harmful leakage. It can itself be a reinforcing material. It is preferable to use another reinforcing wall such as a polyethylene membrane used as a gas permeable membrane. Powder particles or bags filled or affixed with powder particles in the fluid passage or wall, plastic film, fiber,
A packing layer or reinforcement selected from lines, split yarns, cords, nets, cloths, papers, knit products or wastes thereof may be formed to provide a passage filler or permeate transverse to the flow path. When one or a combination operation selected from reaction, decomposition, heat exchange, gas-liquid contact, component separation, and filtration is performed by treating a fluid or a fluid-containing material, the thin plate-like material may remain as a single piece or a plurality of pieces. It is characterized in that it is formed into a sheet, preferably in the shape of a bag or a tube, and is overlapped on the inside or outside thereof, and is combined into a vertical fin shape or a towel squeezed form a fluid flow path. The advantage of this form is that the inlet and outlet of the fluid can be easily connected to the device or piping by using a pipe or a nozzle. Forming a packing layer in the flow path, catalytic substance, metal powder particles, activated carbon, activated carbon fiber, activated carbon cloth, carbide of organic matter,
Adsorbent, oil absorbent, filter aid, porous material, zeolite,
A material selected from ion exchangers, earth and sand, etc., or a composite material thereof may be held between paper, cloth, porous film, netting, etc., or powdered in a quilted manner, held in a fiber holding partition or bag. The flexible lamella or packing phase containing or adhering the catalyst or microorganisms may be a filter medium, a gas permeable medium, an ion exchange medium. A processing electrode or a magnetic material may be incorporated. When a diaphragm between two fluids is required, such as heat exchange, dialysis, and batteries, insert a flexible electrode plate, etc., as a packing into a bag-shaped one with three chambers, and twist it if necessary. I mean
It can be wound into a thick rope. The advantage of the squeezed or rolled shape is that it can maintain its shape and retain its strength while being flexible itself. A thin plastic membrane with good oxygen permeability such as polyethylene is used for aerobic microbial treatment, but the outermost surface is bare and the pressure resistance is small and it is a few meters in water.
Since it swells with m, it is possible to cover the functional unit or the outermost part of the bundle with pressure resistance. This is cloth, paper, thick film,
A net, a spiral, a perforated plate, other frame structures, adhesion or fusion, or a combination thereof can be used. The thin plate, tube or tube forming the passage wall is one or a combination selected from metal foil, air permeable film, porous film, cloth or paper which may be water resistant, and the outside contains air or oxygen. If the pressure in the atmosphere is relatively higher than that of the inner side, swelling is prevented, and in the porous film, bubbles can be supplied at a low pressure. If thin filter cloth of 1 m square is put into a rod shape according to the present invention, the diameter is 3-5.
cm. Although the lengths are almost the same, if they are arranged in a width of 1 m, it becomes 20-30, that is, 20-30 m ² . Similarly, when the surfaces are contacted, heat exchanged or used as a diffusion surface, the effective area in the unit volume is 10
It can be -30 times. Moreover, the processing flow rate can be arbitrarily determined by a test.

[0006]

[Inlet / Outlet connection end]
The mouth can be contracted by contraction or folding, and the ends connected to the connection mouth can be put together, covered with a tube, and tightened with a tightening band to easily join. It is also possible to process the ends and form a tubular connection. Plastic films may be collected as they are, or may be heat-sealed by adding materials or molded using an adhesive. Plates or nets, wires, and threads arranged in a grid pattern corresponding to the connection ports are piled up as packing materials, and rolled up, squeezed with a towel, or twisted with a thick thread. . It can also be organized into strips or vertical fins. These ends can be widened and connected to an inlet or outlet tube. A plurality of the thus-assembled products may be further assembled into a rope or a bundle, or may be assembled like a multiple spiral. It is possible to provide a strainer or a pressure protection function outside the treatment unit to the treatment unit or its entrance.
A straight pipe or a curved pipe may be provided inside the passage to form a large cross-section passage and, if necessary, a connecting end instead of the treatment surface or filler surface passage. It is convenient to use the end as a connecting pipe for the entrance and exit. Similarly, it may be a reinforced structure or a passage structure forming the outer circumference. The connecting pipe is a plug-and-fix type tube plate, or a main plate or a tube plate can be disassembled into mountain-shaped parts that hold the pipe in between and can be disassembled into tube-shaped parts. The connection density can be increased and the functional units can be easily manufactured and connected. The tube plate having the fixed insertion end may be connected to a gas tank, a water tank, or a liquid surface.
A strainer or grate can be installed at the processing section or its entrance to prevent foreign matter from entering. When the number of functional units is small, the pressure-resistant protective function on the outside of the partition wall or the processing section can be expanded in a bag shape into a tank, a water tank, or a connected storage container to form a water-resistant lining. If the storage container is mainly used, a small or large container having a fluid treatment function connected thereto can be obtained, and a special container in which the tube sheet and the connecting portion can be partially omitted can be obtained. In this case, a storage container provided with an insertion tube inside the passage may be used. This storage container is suitable for the storage container of the food waste processing apparatus shown in Japanese Patent Application Nos. 3-228125, 361130 and 4-44323.
Then, it is convenient to stack one or a plurality of sheets to form a bag in the container.

[0007]

[Equilibrium pressure on the flow path surface due to fluid pressure, prevention of blockage and selection of partition wall, packing, filter cloth, etc.] A passage inlet and air outlet are arranged side by side near the water surface, or water and air Aspirating oxygen-containing gas at the same time, aerating, water,
It can treat seawater with low water level and low air pressure. This makes it possible to control a device having a narrow flow passage and a large surface area according to the present invention and its obstruction obstruction. In the microbial treatment, it is premised on the prevention of packing or reaction tank field blockage due to excess surplus sludge,
Therefore, although it was difficult to make a small-sized and small-capacity device, this has become possible. Another advantage of the present invention is that it is difficult to use due to its non-water resistance (for example, plain paper, newsprint), paper which has been difficult to use as a filter medium or filler, catalyst, microbial carrier, and amorphous shape. Fiber products or their waste
Rather, it is easy to use because of its indefinite shape, and its shape can be retained and used by stacking it with a film or a thin plate and applying a twist. Needless to say, adhesive or stapler may be applied partially or entirely, or puncture holes may be used on paper, film, etc.
You may punch a hole. Newspaper, for example, can be used as a filter for sewage or as a biochemical treatment carrier and can be disposable after use. Furthermore, the water filtration or water treatment device according to the present invention can be used as a disposable filter device, an adsorption device, a biochemical treatment device, etc. by charging it into a paper pack container such as that used for milk, liquid foods and medicines. It is preferable that the blockage and its removal are easy in the microbial reaction, wastewater treatment, filtration and other treatments, but the partition wall, the packing, and the thin filter material can be easily selected from a wide range by experiments together with the operating conditions in which the blockage is difficult. This is because the shape, thickness, smoothness, adhesiveness, strength, and liquid resistance of the material itself are less restrictive than the conventional technology, and the volume density, passage gap, temperature, pressure, etc. of a unit device can be reduced. This is because the structure can be applied uniformly to the surface of each filtration unit. This secures a clearance on the outer surface of the flow path and is assembled into a structure similar to a shell-and-tube heat exchanger of a tubular type or a tube type or a U type or a lattice type heat exchanger, and This is because the conditions can be easily adjusted by adjusting the pressure. It is possible to discharge or backwash particles and blockages captured on the surface while expanding the passage by backflowing gas / liquid or adjusting the pressing pressure. Similarly, through the passage wall to the passage, fluid pressure,
A variable or fixed pressure selected from tension, twist, and mechanical compression can be applied to fix or adjust the passage specifications to determine the filtration condition and the regeneration condition. The application of vibration promotes the effects of both conditions. Fluid pressure control is based on inlet / outlet differential pressure, flow rate,
It can be done manually or automatically according to the measurement of effluent quality.
In the case of backwashing the occluded material, the apparatus can be operated by reversing the inclination or standing upside down. As a result, a complicated and expensive mechanism such as valve switching and operation can be omitted, and the device can be used as a simple device. This is made possible by reducing the weight of the device. When the particles separated from the fluid are removed from the passage or the processing function is restored, the passage is relaxed and the same fluid or a recovery fluid is circulated for recovery, or the passage is relaxed or continuous according to the change in filtration conditions. The operation can be continued. Before the collected particles are discharged, the particles can be compressed or dehydrated by pressurizing them from the outside, and the device according to the present invention can make each functional unit collectively from the outside of the passage or form a relatively uniform surface from the outside gap of each wall of the passage. It utilizes the advantage that dispersed pressure and pressure can be applied. The conditions can be determined by selecting the characteristics of thin partition walls and passages, cake peelability, surface strength, etc. by preliminary tests. In the gas phase treatment, a narrow passage gap that can supply a treatment, recovery or cleaning fluid together with the gas phase can relax the passage when pressure loss is excessive, or apply pulsation or vibration for blockage removal. it can.
This can be due to fluctuations in the fluid on the passage side or the fluid for pressurization on the outside. The conventional treatment equipment does not have the ability to control these obstacles freely, and it is difficult to smoothly treat wastewater with large concentration fluctuations and waste, and there is the problem that an excessive tank, water tank, etc. are required for uniform treatment conditions. there were. One of the features of the present invention is that the shape of the processing functional material can be self-retaining by drawing, twisting, and friction caused by them, the reinforcing material is small, the weight is light, and the selection range of the material and the shape is relatively wide. Overall, it is lightweight and can be simplified. Most of the weight of conventional filters and the like is a reinforcing material. Therefore, as compared with the conventional device, a low cost device can be realized, a small amount of fluid can be processed, and the size can be easily increased. Fine particles,
It is easy to prevent foreign matter from entering and obstructing obstruction due to sticky matter, and a disposable device is also possible when fluid or separated matter recovery is not required. In the filtration of occlusive particles, the amount of filtrate passing per filtration area was small and the passage cross-sectional area was originally small.However, conventional filtration devices cannot increase the filtration area within a unit volume, resulting in a high efficiency. It was bad. In the present invention, since the amount of staying in the passage of the device or the hold-up is small, it is easy to collect the blockage. Further, in the conventional filtering device or filter cloth, the particle size which can be separated according to the material has been decided. In the present invention, the passage gap can be easily adjusted, so that it can be selected. Combined with the choice, there is the benefit of adjusting the aperture. Part of the thin plate or film is the waste storage container or its lining and stores the waste in the storage container,
Effluent fluid from waste can also be treated or channeled. This takes advantage of the flexibility of the flow path to facilitate seam connection and closure of containers, outlets. It is preferable to use a relatively smooth material for the inner surface of the flow path, so that the clogging material and the filter cake can be easily detached. Since it is difficult to block and can be easily removed, it is easy to downsize the exposure device for biochemical wastewater treatment such as activated sludge method, which was difficult in the past, and it is lightweight, low in head, low in blowing pressure. The processing equipment is ready. And since power consumption is reduced, solar cells can be used as a power source,
Floating on the surface of the water where there was a problem in terms of power wiring and processing, and enabling water purification in remote areas. In other words, it enables a plant that can be installed anywhere.

Embodiment 1 FIG. 1 is a diagram showing an example of a fluid treatment device according to the present invention. It can be used in a wide range of applications as described in the section "Industrial application" depending on the selection of constituent materials and operating conditions. First, the case of use as a flow-down type filtration device will be described. As a flexible thin plate, a filter cloth and a passage spacer material are stacked on a tubular or bag-shaped body of general-purpose high-density polyethylene film as shown in the cross-sectional view in FIG. As shown in FIG. 10, it is inserted into the plate 5 and is inserted into the tightening tube plate 4 with the tightening tool 7. Inserting long wedges 48 and 49 into the wedge hole of 5 to prevent the tube from rotating and fixing it to the tube sheet. It is convenient to pass multiple wedges and also serve as a rotation stop, and it is also convenient to insert the tube into the tube sheet. However, a stopper may be provided on the tube sheet with a separate wedge. The filtration part, which is a stack of films, is used as a filtration function unit by squeezing towels into a rod shape. May be. As shown in FIG. 4, an expansion preventing tool such as a net, expanded metal, plastic, a perforated plate or a frame may be covered from outside the rod-shaped functional unit. The fluid supply may be continuous or intermittent. In the case of mud filtration, the flow direction is
Muddy water 25 adjusted to a constant water level by overflow pipe 16 in upper chamber 18
It flows in from the inlet 41 and spirally flows down in the integrated flow channel 3 shown in the cross section in the form of a thin film. The particles are sandwiched between the flow channel walls and collected and filtered by the vertical depth, and from the outlet 44 to the lower chamber 26. It falls and is discharged from the pipe 11 through the valve 12. The flow path thickness, that is, the particle collecting ability can be opened or closed by pressurization or depressurization depending on the difference between the water levels 13 and 18 of the pressurizing pipe 14. When the flow path is closed, the shell side 8 is depressurized by the pressure adjusting device 14 to expand the flow path, and the water flow can be pushed away. The pressure on the entrance 41 side may be increased. Vibration is applied by the vibrator 21, and the discharge can be promoted by the thixotropic phenomenon. The tank 26 can be operated with the suction pressure from the valve 12 even when it is open to the atmosphere. To remove dust in the gas phase, lower the water level of 25 and operate the wet wall tower at the introduction part,
At the same time, by introducing a gas phase such as air, dust is removed by gas-liquid contact or wall adhesion. In the case of dry type, the flow path is narrowed to collect. The thickness of the flow channel can be selected easily by experimenting with the material and the external pressure of the flow channel. The fluid bypass line 58 may utilize the pressure tube 14. FIG. 2 is a plan view of FIG. Reference numeral 54 is a dividing portion which is convenient for assembling and disassembling processing units such as filtration. Numeral 50 is a fastening tool in the case of its assembly, and a known mechanism can be used. Although they can be stacked like a filter plate of a pressure filter, there is an advantage that a plurality of filter cloths can be stored in one section and thus the filtration area becomes large. The number of processing units per section is one or more, and can be arbitrarily selected from single row and double row. If necessary, a known method can be used for sealing between the tube and the tube sheet and the compartment. The processing capacity of water and liquid is 0.1 per processing unit depending on the equipment size, material and processing conditions.
It was −100 L / hour. 0.2 in the case of gas phase
It was about −2 m ³ / hour.

[0009]

[Embodiment 2] As the processing unit 2 in FIG. 1, the one shown in the sectional principle view of FIG. 5 is used. A filter material 31, such as a filter cloth, a filter paper, or a porous plastic film, is used and permeates from the stock solution flow path 42 to the furnace solution flow path 43. Turbid water in the water channel was filtered using newspaper as a filter medium. A 55 × 80 newspaper sheet and a high-density polyethylene bag corresponding to the sheet were stacked to form a processing unit, and a tubular device was assembled and used. The filtration amount is 0.
At 2 L / h, the filtrate was clear. When a filter cloth was used, it was 1-30 L / hr.book depending on conditions. Gas phase filtration is likewise easy. When the flow rate is too low, a filling material such as a mesh or a wire can be inserted to secure the flow path thickness.

[0010]

[Embodiment 3] FIG. 8 shows a cylindrical or bag-shaped filter medium 46 on the shell side 8.
In this example, the stock solution or dust-containing gas is introduced from the shell side. The filter medium may be lined with a flexible mesh or a perforated plate. In order to prevent excessive expansion during backwashing, it is preferable to prevent deformation by the protection means 35 as in FIG. If you secure the passage, in similar conditions, conventional vacuum filtration, obtained pressure filtration equivalent filtration area per capacity, the volume per capacity reaches more than 10-100 times. This is because there is little wasted space, the degree of freedom in selecting filtration conditions is wide, and the frequency of backwashing can be increased. Even in the vapor phase filtration, it was 10-100 times more powerful than the bag filter with a similar simple structure. It is especially effective when the dust content is low.

[0011]

Example 4 The treatment unit shown in FIG. 8 was used for treating aerobic microorganisms. In the configuration of FIG. 1, the shell side 8 is provided with natural ventilation or forced ventilation. Therefore, the shell 1 may be removed and only the support frame having four corners may be used. 14 is also unnecessary . However, deformation can be prevented by wrapping the outside of 2 with a reinforcing net or the like so as not to obstruct ventilation. The circulation pump 57 is used when the BOD is not sufficiently decomposed in one pass. Suction pressure can be applied from 2 sides by applying suction pressure from 11. If the amount to be processed is sufficiently small and about 1-10 L / day / piece, thin polyethylene film is enough for the two sides. In the case of blockage of the flow channel, pressure was applied to the flow channel to remove excess sludge and allow it to flow. Sewage COD is from 30PPM to 30P
It fell below PM.

[0012]

[Example 5] The oil film floating on the surface of the storage pit of the sludge accumulated in the road gutter and the sewer was removed. Using commercially available oil film removal polypropylene nonwoven fabric 2 faces, they were assembled processing units as in FIG. It was repeatedly passed through the irrigation system. The water surface oil film was easily removed. At the same time, the water was aerated, and deodorized and COD was reduced and purified.

[0013]

Both countercurrent flow and parallel flow are possible and suitable for low temperature differential heat utilization.
The operating conditions differ depending on the type of fluid and the target thermal efficiency, and can be obtained by experiments, and the capacity per volume is large, but the heat transfer coefficient was equivalent to that of a normal thin film heat exchanger.

[0014]

It can be used for both downflow and upflow depending on the conditions. The air from the blower 60 is vertical piping 63.
Then, the air enters into the bubble tube 62, and by the bubble transportation, the circulating wastewater containing a small amount of sludge is fed by the bubble pump into the thin carrier flow path to which the microbial membrane is attached. With the channel extends the angled stay time, the water pressure, divides the flow path from the outside, substantially uniformly hold the channel thickness. Reference numeral 57 is a crude water supply pump, and the purified water overflows and is discharged by the supplied amount. It is also possible to keep the phase 18 at a reduced pressure by using the exhaust fan 66 and suck up water and air to make it an upflow type. 61 is a power source by a solar cell, 6
8 is a control valve and 67 is a mooring tool. Blowers, pumps, etc. need only low pressure and small power.

[0015]

Seventh Embodiment FIG. 15 shows an example in which, in addition to the partition wall surface flow, there is a flow through which a fluid passes in the thickness direction of the filler. Downstream of the filler permeation, a relatively coarse spacer can be inserted to facilitate permeate flow. Filtering or contacting is different from the conventional mechanism in two directions, the flow direction and the crossing direction of the flow, so that obstruction due to blockage, deterioration, poisoning, etc. is unlikely to occur.

[0019]

[Embodiment 8] FIG. 16 shows a flow state in suction pressure operation of an air chamber, an air hole 67 on the lower surface or the upper surface of the air chamber. The holes can be formed by various known methods.
