Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an oil decomposing adsorption tank for separating emulsified oil. More specifically, the present invention performs oil-water separation treatment on emulsified oil to remove drain water after treatment. It is related with the oil decomposition adsorption tank which isolate | separates the emulsified oil which becomes clean to the extent that it can be discharged as it is.
[0002]
[Prior art]
Conventionally, as a technique related to an oil decomposition adsorption tank for separating emulsified oil, an electrolytic method, a salting-out agent, a flocculant, an adsorbent, and the like are added, and oil water is added by pressure flotation, coagulation precipitation, or filtration. There are a method of performing separation, a method of dissolving and extracting oil with a solvent, and the like. In this case, either method requires a large-scale facility or a long-time treatment in order to satisfy the recent allowable limit of 5 ppm or less for the treated drain water with mineral oil. Had the disadvantages.
[0003]
In addition, oil and water separation by a filtration method with relatively simple equipment and facilities is effective for dispersed oil or floating oil, but it is difficult to filter the emulsified oil. It was.
[0004]
In order to remedy the drawbacks of these treatments, firstly, the emulsified oil was impregnated with a non-woven fabric or a support, and the emulsified oil was separated. There are some which are laminated in multiple layers, and thirdly, an oil adsorption treatment is performed after the first treatment.
[0005]
Fourthly, as seen in Japanese Patent Publication No. 7-98124 by the inventor of the present application, the granular amine and the oil adsorbent are separated, and the middle cylinder having a smaller cross section than the case is accommodated in the cylindrical sealed case. Some of the space inside and outside the inner cylinder was filled.
[0006]
[Problems to be solved by the invention]
However, the conventional oil decomposition adsorption tank for separating drain water generated from compressed air has the following problems.
[0007]
First, regarding the first and second, oil adsorption treatment is also performed with a nonwoven fabric or support impregnated with an amine compound, but the oil adsorption ability is low because the amine compound is impregnated. Therefore, in order to ensure a certain ability, it is necessary to increase the amount of the nonwoven fabric impregnated with the amine compound and the support, and there is a problem that the entire apparatus is enlarged.
[0008]
Moreover, regarding the third, although the treatment capacity for oil adsorption was improved, two tanks, a decomposition tank and an adsorption tank, were required. Accordingly, the preparation of two tanks increases the overall size of the apparatus, and the management of the two tanks has the problem of complicating the management and replacement of amine compounds and nonwoven fabrics that are consumables.
[0009]
Finally, regarding the fourth, although the oil adsorption processing capacity has been improved and the apparatus has been considerably reduced in size, it has become a complicated shape in which a middle cylinder with a small cross section is accommodated in a cylindrical sealed case. In addition, there is a problem that the management and replacement of the granular amine which is a consumable and the oil adsorbent are complicated.
The present invention aims to solve such problems.
[0010]
[Means for Solving the Problems]
In the present invention, an oil adsorbent 342 that adsorbs oil and an amine 341 that destroys the emulsified oil are constituted by a cylinder 301 and upper and lower lids 302 to prevent leakage of fluid inside and allow drain water to pass. Filled in a state of being dispersed in the tank 61, the oil adsorbent 342 is a small piece of 100 mm × 50 mm or less. Two kinds of small pieces with different sizes of 3 to 10 times in area were prepared. Furthermore, an oil adsorbent 342 that adsorbs oil and an amine-supported body 345 in which an amine 341 that breaks down the emulsified oil is attached to the support 344 are formed by a cylinder 301 and upper and lower lids 302.

[0013]
Here, the compressed air stored in the air tank 13 passes through the compressed air pipe 111, the aftercooler 20, the compressed air pipe 112, the dryer 30, the compressed air pipe 113, the air filter 40, and the compressed air pipe 114. Compressed air can be supplied via.
[0014]
In this case, the compressed air is dried by the aftercooler 20 and the dryer 30 and the foreign matter is removed by the air filter 40 so that the dried beautiful compressed air can be fed.
[0015]
On the other hand, from the lower part of the air tank 13, a drain pipe 121, an openable / closable valve 122, a drain pipe 123, an electric drain trap 124 that discharges drain water together with compressed air by some signal, and a drain pipe 125. It is connected to the drain collecting pipe 161 via, and drain water can be discharged.
[0016]
Further, the aftercooler 20 includes a drain pipe 131, a valve 132 that can be opened and closed, a drain pipe 133, an electric drain trap 134 that discharges drain water together with compressed air in response to some signal, and a drain pipe 135. Via, it is connected to a drain collecting pipe 161, and drain water can be discharged.
[0017]
Further, from the dryer 30, the drain pipe 141, the openable / closable valve 142, the drain pipe 143, the electric drain trap 144 that discharges drain water together with the compressed air by any signal, and the drain pipe 145 are passed through. Then, it is connected to the drain collecting pipe 161 so that drain water can be discharged.
[0018]
In addition, from the air filter 40, a drain pipe 151, a valve 152 that can be opened and closed, a drain pipe 153, an electric drain trap 154 that discharges drain water together with compressed air by any signal, and a drain pipe 155. It is connected to the drain collecting pipe 161 via, and drain water can be discharged.
[0019]
Here, from the drain collecting pipe 161, fresh water is discharged from the fresh water pipe 173 via the check valve 162, the drain collecting pipe 163, and the oil / water separator 210 for separating oil and various foreign substances. Yes. In this case, the check valve 162 allows drain water to pass from the drain collecting pipe 161 to the drain collecting pipe 163, but does not cause the drain water to flow backward from the drain collecting pipe 163 to the drain collecting pipe 161. Moreover, the fresh water discharged | emitted from the fresh water pipe 173 is purified to such an extent that it can be discharged into the river as it is.
[0020]
The oil / water separation device 210 includes an oil / water separation tank 50 and two oil decomposition / adsorption tanks 60, and the oil / water separation tank 50 and the oil decomposition / adsorption tank 60 are connected by a fresh water pipe 171. 60 is connected by a fresh water pipe 172. However, the oil decomposition adsorption tank 60 does not need to be limited to two, and may be one, three, or more.
[0021]
In this case, the oil / water separation tank 50 is configured such that the compressed oil, which is a gas, can freely enter and exit the upper part of the sealed oil / water separation tank body 50a, and the drain water, which is a liquid, can freely enter and exit at the lower part. It is partitioned by a partition plate 50d so as to communicate with each other, thereby forming two chambers, an oil floating separation chamber 50b and a water storage chamber 50c.
[0022]
And the other end of the inlet pipe 50e connected to the drain collecting pipe 163 via the joint 50h is located in the upper part of the oil floating separation chamber 50b, and drain water flows into it. Therefore, in the oil floating separation chamber 50b, oil lighter than water floats on the liquid surface, and foreign matters heavier than water settle on the bottom.
[0023]
On the other hand, in the water storage chamber 50c, the pipe end 50g, which is the end of the outlet pipe 50f, is positioned on the liquid surface, and is lighter than water than the lower communicating portion between the oil floating separation chamber 50b and the water storage chamber 50c. Drain water from which foreign substances heavier than oil and water have been removed flows. Here, the outlet pipe 50f is connected to the fresh water pipe 171 through the joint 50i. Therefore, clean drain water from which the oil collected on the liquid surface of the water storage chamber 50c is removed is fed into the outlet pipe 50f.
[0024]
The oil decomposition adsorption tank 60 includes a tank 61 filled with an amine 341, an oil adsorbent 342, and activated carbon 343, a base 321 that fixes the tank 61 to the ground, and four tanks that fix the tank 61 to the base 321. It is comprised from the nut 305.
[0025]
The tank 61 includes a cylinder 301, two upper and lower lids 302, two upper and lower O-rings 303 that prevent fluid from leaking inside the cylinder 301, and two upper and lower parts sandwiching the O-ring 303 and the cylinder 301. Four bolts 304 penetrating through one lid 302, cylinder 301, two upper and lower O-rings 303 at each end of the bolt 304, eight nuts 305 for fixing the lid 302, and fresh water pipes 171, 172, 173 The upper and lower hose joints 310 are connected to each other.
[0026]
Further, the hose joint 310 is composed of a joint main body 311, a nut 312, and a sleeve 313, and the male thread portion of the joint main body 311 is connected and fixed to the central portion of the lid 302 by screwing. In this case, in the hose joint 310, the sleeve 313 is inserted into the fresh water pipes 171, 172, 173, and the joint body 311 and the nut 312 are coupled by screwing in a state where the sleeve 313 is sandwiched between the joint body 311 and the nut 312. The fresh water pipes 171, 172, and 173 are fixed to the oil decomposition adsorption tank 60 through the hose joint 310. The fresh water pipes 171, 172, 173 may be steel pipes or vinyl pipes.
[0027]
In addition, an oil adsorbent 342 that adsorbs oil or oil that has been replaced is exchanged inside the cylinder 301 because the function deteriorates when a period in which the fluid flows in the cylinder 301 is used. The amine adsorbing material 340 in which the amine 341 that breaks down and coarsens the destroyed oil adheres to the oil adsorbing material 342 and the activated carbon 343 that adsorbs a bad odor are filled.
[0028]
In this case, space portions 301 a are secured on the inlet side and the outlet side, which are both ends of the cylinder 301, so that the drain water that is liquid flows uniformly at each point on the cross section perpendicular to the flow in the cylinder 301. ing. Therefore, in order to secure the space portion 301a, the punching plate 331 having a large number of small holes is supported by disposing the cylindrical gap cylinder 332 having a smaller diameter than the cylinder 301 between the lid 302 and the amine 341. The oil adsorbent 342 and the activated carbon 343 are filled between two punching plates 331.
[0029]
The amine-adsorbed adsorbent 340 and the oil adsorbent 342 increase in resistance as they absorb foreign substances such as oil, and are pressed against one side while being compressed, so that the function of oil breakdown and oil adsorption is reduced. To do. Therefore, in order to prevent this even a little, an intermediate perforated plate 333 having a large number of small holes is disposed in the substantially central portion of the cylinder 301 so as to vertically block the liquid flow, and the intermediate perforated plate 333 is attached. In order to support, the compression preventing means 333 and 334 are configured by disposing a cylindrical holding cylinder 334 having a smaller diameter than the cylinder 301 between the intermediate porous plate 333 and the punching plate 331.
[0030]
As shown in FIG. 2, activated carbon 343 is disposed immediately downstream of the intermediate porous plate 333 inside the cylinder 301, and both the amine adsorbent 340 and the oil adsorbent 342 are dispersed and scattered. The remaining part is filled. In this case, the activated carbon 343 may be disposed immediately upstream of the intermediate porous plate 333 or may be disposed immediately before or immediately before the punching plate 331 at the inlet or outlet. Further, the amine 341, the oil adsorbent 342, and the activated carbon 343 may be filled in a dispersed state. Here, as a method for bringing the amine 341 into close contact with the oil adsorbent 342, a method in which a solution obtained by dissolving the amine 341 in a solvent is brought into contact with the oil adsorbent 342 and then the solvent is evaporated and dried. There is also a method of spraying the oil adsorbent 342 in the form of a mist.
[0031]
Further, the remaining portion may be filled in such a state that the amine 341 and the oil adsorbing material 342 are dispersed apart without being in the state of the oil adsorbing material 340 with the amine. Also in this case, the activated carbon 343 may be disposed immediately upstream of the intermediate porous plate 333, may be disposed immediately before or immediately before the punching plate 331 at the inlet or outlet, or the amine 341 and the oil adsorbent 342. You may fill in the state disperse | distributed separately.
[0032]
However, in any of the cases described above, a configuration in which the activated carbon 343 is not disposed is also conceivable.
[0033]
On the other hand, the amine 341 used in the present invention may be an amine compound or a derivative thereof, and is preferably solid when the amine compound or the derivative is 25 ° C., but the compound is non-solid at 25 ° C. Even if it is in the form of a solid, it may be a compound that becomes a solid in a mixture with other compounds. That is, the compounds may be used alone or in combination of two or more.
[0034]
These amine compounds and derivatives thereof are preferably primary amines, secondary amines, tertiary amines and derivatives thereof, more preferably primary amines, secondary amines and derivatives thereof, particularly preferably. Are primary amines (eg stearylamine) and derivatives thereof.
[0035]
Examples of these amine compounds include primary amines such as hexylamine, hebutylamine, octylamine, nonylamine, decylamine, laurylamine, myristylamine, palmitylamine, oleylamine, stearylamine, or hydrocarbon chains thereof. Secondary amines such as diamines and triamines, and tertiary amines, or their picrads, various salts (for example, salts of hydrochloric acid, sulfuric acid, phosphoric acid, carbonic acid, acetic acid, etc.), and these hydrocarbon chains Primary amines, secondary amine acid amides, amidines, ureas, thioureas, and primary amine Schiff bases.
[0036]
As the amide, sulfonamides such as p-toluenesulfonyl-N-stearylamide and N-stearylacetamide are preferable. Moreover, the quaternary ammonium salt, betaine, etc. which have these hydrocarbon chains are mentioned. Furthermore, for example, polyvalent amines such as stearyl propylene diamine and semi-cured beef tallow diamine can be used. Furthermore, it is also possible to use a mixture of amines having hydrocarbon chains having different carbon numbers such as hardened beef tallow amine and coconut amine.
[0037]
Further, as the oil adsorbing material 342, one made of polypropylene or polystyrene fibers can be considered. However, the oil adsorbing material 342 is not limited to these, and other materials may be used as long as they have an oil adsorbing function and do not require water.
[0038]
Here, the size of the oil adsorbent 342 is preferably (10 mm to 200 mm) × (2 mm to 50 mm), more preferably (30 mm to 80 mm) × (5 mm to 40 mm). That's it. In particular, it is most preferable to prepare two types of sizes of (35 mm to 55 mm) × (25 mm to 40 mm) and (40 mm to 60 mm) × (3 mm to 10 mm). From another viewpoint, this can be said to be close to the idea of preparing two types of small pieces of 100 mm x 50 mm or less and 3 to 10 times different in area. It can be said that it is ideal to prepare two kinds of small pieces of 60 mm × 40 mm or less and different sizes 4 to 8 times in area.
[0039]
In this case, such a size is preferable because when the oil adsorbent 342 is filled in the tank 61, if the size is too large, it is difficult to fill a large amount due to a large gap, so that a large surface area is obtained. It is difficult, and there are many parts that are forcibly compressed, but the function of breaking and adsorbing the emulsified oil is reduced in such parts, and the amount to be filled cannot be ensured, so the performance cannot be secured, If it is too small, the gaps are basically small, so the oil that has been emulsified breaks down and the function of adsorption is reduced quickly, and it is troublesome to cut and various kinds of management.
[0040]
In addition, using two kinds of sizes means adding two kinds of small pieces of different sizes, and adding small ones to the large gaps and unreasonable compression that are the challenges of making them large It has a great meaning that it can be compensated by adding large things to the early decline in function, which is a problem of making it small at the same time.
[0041]
As for the two types of small pieces, FIG. 2 shows that a small piece is used for the oil adsorbent 340 and a small piece for the oil adsorbent 342, but the amine adsorbent 340 and the oil adsorbent are used. Two kinds of small pieces may be used for both of the materials 342, and a small piece for the amine adsorbent 340 and a large piece for the oil adsorbent 342.
[0042]
The oil decomposition adsorption tank for separating drain water generated from compressed air according to the present invention is configured as described above, and its operation will be described below.
[0043]
First, when the motor 11 constituting the air compressor 10 is operated, the rotation of the motor 11 is transmitted to the compressor 12 via the belt 14 and the compressed air is stored in the air tank 13. Here, the compressed air stored in the air tank 13 passes through the compressed air pipe 111, the after cooler 20, the compressed air pipe 112, the dryer 30, the compressed air pipe 113, the air filter 40, and the compressed air pipe 114. It is possible to send dry and clean compressed air to the actuators of this as needed.
[0044]
On the other hand, the drain water generated from the compressed air by the air tank 13, the aftercooler 20, the dryer 30, or the air filter 40 together with the compressed air, the drain pipes 121, 131, 141, 151, the valves 122, 132, 142, 152, and the drain pipe 123. 133, 143, and 153, drain traps 124, 134, 144, and 154 and drain pipes 125, 135, 145, and 155, merge at drain collecting pipe 161, and check valve 162 and drain collecting pipe 163 It is sent to the oil / water separator 210 via the water, and the oil / water separator 210 removes various foreign substances including oil, and can be made into clean water that does not have any problem even if it is discharged from the fresh water pipe 173 into the river as it is. It has become.
[0045]
In this case, in the oil / water separator 210, first, in the oil floating separation chamber 50b of the oil / water separation tank 50, oil lighter than water is floated on the water surface, and various foreign matters heavier than water are precipitated at the bottom, and the oil floating separation chamber 50b The clean drain water from which oil and various foreign substances have been removed is fed into the water storage chamber 50c through the lower communicating portion between the water storage chambers 50c. On the other hand, the compressed air sent together with the drain water stays in the upper part of the oil / water separation tank 50.
[0046]
Here, when the drain water sent into the water storage chamber 50c accumulates above the pipe end 50g, which is the end of the outlet pipe 50f disposed in the water storage chamber 50c, the drain water stays in the upper part of the oil / water separation tank 50. The compressed air is fed into the oil decomposition adsorption tank 60 through the outlet pipe 50f and the fresh water pipe 171. In this case, the force of the compressed air assists the movement of the drain water until the drain water is discharged from the fresh water pipe 173 because the oil decomposition adsorption tank 60 is in a sealed state.
[0047]
However, although oil and various foreign substances are separated in the oil floating separation chamber 50b of the oil / water separation tank 50, the emulsified oil is sent to the oil decomposition adsorption tank 60 in a state of being dissolved in the drain water.
[0048]
Therefore, in the oil decomposition adsorption tank 60, the oil that has been emulsified comes into contact with the amine 341 of the oil adsorbent 340 with the amine 341 attached to the oil adsorbent 342, and the oil is separated from the water. The oil that has become coarser. Then, the cleanliness of the drain water is improved by the coarsened oil being adsorbed by the oil adsorbent 342. Further, when the drain water passes through the activated carbon 343, the odor is removed.
[0049]
In this way, depending on the amount of drain water and the degree of contamination, it is possible to connect one or more three or more oil decomposition adsorption tanks 60.
[0050]
As an example, concretely, how much is filled is shown as a cylinder with an inner diameter of approximately 200 mm and a height of 950 mm with respect to a drain generated from a screw type air compressor of 37 Kw to 75 Kw. In addition, 2.5 kg of 45 mm × 25 mm amine-adsorbed oil adsorbent 340 which is a polypropylene nonwoven fabric, 2.5 kg of 45 mm × 5 mm oil adsorbent 342 which is a polypropylene nonwoven fabric, and 1 kg of activated carbon 343 are filled. The tank 71 is used in the form of two installed tanks.
[0051]
(Second embodiment)
The difference between the second embodiment and the first embodiment is that the oil decomposition adsorption tank shown in FIG. 3 is shown in FIG. 1 instead of the oil decomposition adsorption tank 60 whose detailed contents are shown in FIG. 70 is installed.
[0052]
Here, in the oil decomposition adsorption tank 70 shown in FIG. 3, in the first embodiment, the amine 341 adheres to the oil adsorbent 342 to form the amine adsorbent 340, whereas the oil decomposition adsorber 340 shown in FIG. In the embodiment, the amine 341 is attached to the support 344 to form the amine-supported support 345.
[0053]
In this case, as the support 344, a water-insoluble inorganic substance and organic substance can be used. Examples of inorganic substances that can be used include silica, alumina, molecular sheep, zeolite, activated carbon, diatomaceous earth, sand, activated clay, asbestos, glass fiber, and grass charcoal fiber. As the organic substance, a natural or synthetic polymer is used.
[0054]
The natural or synthetic polymer may be of any kind as long as it is insoluble in water. Examples of natural products include cellulose, wool, silk and the like. In addition, natural products such as cellulose derivatives such as acetylcellulose, nitrocellulose, methylcellulose, ethylcellulose, and carboxymethylcellulose may be used.
[0055]
Examples of the synthetic molecular polymer include styrene derivatives such as styrene and α-methylstyrene vinylbenzene, acrylic acid derivatives such as acrylic acid, methacrylic acid, methyl methacrylate, ethyl acrylate, butyl acrylate, acrylamide, and methacrylamide. Ethylene unsaturated monomers such as ethylene, propylene, butylene, vinyl acetate, vinyl chloride, vinyl chloride, vinylidene chloride, acrylonitrile, methacrylonitrile, and diene monomers such as butadiene, isoprene, chloroprene, etc. Examples thereof include a homopolymer obtained using a monomer, a copolymer using two or more of the above monomers, and the like. Furthermore, examples of the condensation or addition polymer include polyurethane, polyurea, polyethylene terephthalate, polyethylene naphthalate, polybutylene terephthalate, nylon, aromatic polyamide, polycarbonate, polyphenylene oxide, polysulfone, and polyether. Sulfone is also used. It is also possible to use a blend of two or more of the above polymer polymers.
[0056]
In addition, as the thermosetting resin, for example, phenol resin, epoxy resin, phenol epoxy resin, amino resin, petroleum resin, and the like can be used.
[0057]
In addition, about two types of small pieces shown also in 1st embodiment, in FIG. 3 which shows 2nd embodiment, the two types of small pieces which are different in a magnitude | size to both the support body 345 with an amine and the oil adsorbent 342 are shown. Although used, a small piece may be used for the support 345 with amine and a small piece for the oil adsorbent 342, or a small piece for the amine adsorbent 345 and a large piece for the oil adsorbent 342. May be used.
[0058]
The configuration and operation of the oil / water separation tank 50 are the same as those of the first embodiment, and the configuration and operation of the oil decomposition adsorption tank 70 are the same as those of the oil decomposition adsorption tank 60 shown in the first embodiment. Using the support 345 with amine instead of the oil adsorbent 340 with amine, only the relationship between the two kinds of small pieces is different as described above. Details are omitted here.
[0059]
【The invention's effect】
As is clear from the above description, the present invention can provide the following effects.
[0060]
First, an oil adsorbent that adsorbs oil and an amine that breaks down the emulsified oil, and an amine that adsorbs an oil adsorbent that adsorbs oil and an amine that breaks down the emulsified oil are attached to the oil adsorbent.
