Description

TECHNICAL FIELD The present invention relates to a water vaporizer used to evaporate only water from wastewater such as household waste, physiological waste, industrial waste, and sludge. .

[Conventional technology]

Conventionally, it is often the case that waste water containing a large amount of water such as household waste, human excrement such as urine, sludge, and industrial waste is evaporated to separate the water from the contained substances. As a simple method for such a purpose, there is a case where sewage is put in a metal container such as a pan and heated from the outside to evaporate water. This method has been practiced outdoors for a long time.

However, simply heating the sewage causes the moisture to be diffused into the air to generate a bad odor, and such a treatment method cannot be implemented in the city and the like. In addition, there are many inconveniences such as using an open fire and requiring a large space.

Therefore, it is necessary to evaporate the water in the sealed container. This is because if the water is evaporated in a sealed container, it is safe and sanitary without using an open flame.
For this purpose, the same applicant as the applicant of the present application, for example, as in Japanese Patent Application No. 63-113113, stores a heater in a sealed container, and the heat of the heater makes it safe and hygienic. I proposed a method to evaporate water.

In this new evaporation device, a water tank for storing water, a partition body that is housed in this water tank and has a heat insulating ability to partition the space in the water tank, a heater housed in this partition body, and an internal space of the partition body are provided. It is composed of a plurality of stored heat storage bodies. In this mechanism, the water tank is divided into compartments, and only the water in the compartments is heated. At the same time, the heat from the heater is stored by the heat storage body, and the large surface area heats the water, resulting in a fast evaporation rate of water, which is effective for treating waste such as sewage and urine from households. .

However, in this method, since water is evaporated in a closed container, the residue (non-volatile solid components, etc.) of sewage stored in the water tank adheres to the inner wall of the water tank, partition, heat storage body, etc. Had to be cleaned regularly as these residues and debris accumulate. However, since the internal structure of this moisture evaporator is complicated, the cleaning work is complicated, and there are drawbacks that it is troublesome and the details cannot be completely cleaned.

[Problems to be Solved by the Invention]

Thus, in the newly proposed moisture evaporator,
Since the space in the water tank is divided by the partition and only the water in the partition is not heated unnecessarily, the evaporation rate of water can be increased. However, since the partition is installed in the water tank, the partition is removed for regular cleaning, the inside of the water tank is cleaned, the inner and outer walls of the partition are cleaned, and each small heat storage body is also cleaned. The work that must be done is occurring.

In order to eliminate this drawback, it is only necessary to remove the partition so that it can be easily cleaned. However, if the object to be evaporated is urine or an organic metal solution, the worker dislikes it and it is toxic. Since the human body comes into contact with various components, there is a drawback that the compartment cannot be removed and the inside cannot be sufficiently cleaned.

Therefore, in the present invention, it is an object of the present invention to make the partition body and the heat storage body disposable so that unnecessary cleaning work can be omitted, the health of the worker can be maintained, and quick maintenance management can be performed.

[Means for solving problems]

In the present invention, a closed water tank for storing water, and the inside of the water tank, which has a hollow three-dimensional shape and has upper and lower openings, whose lower opening is slightly above the bottom of the water tank. A partition body made of porcelain that divides the space inside the water tank into two parts, inside and outside by positioning the upper opening below the ceiling of the water tank, and heat is stored in the internal space of this partition body. The present invention provides a water vaporizer characterized by comprising a heater and a plurality of heat storage bodies which are housed in the internal space of the partition body and provided with gaps through which water can flow.

[Action]

In the present invention, the material forming the partition is made of pottery or porcelain, and when it becomes time for regular cleaning, the partition removed from the water tank is destroyed and stored inside. It is designed to release a certain heat storage body. Then, the destroyed partition body and heat storage body can be discarded while the residue and sludge are still attached, and the number of cleaning steps can be simplified.

Further, if only the inner wall of the water tank is cleaned, the device can be reused by incorporating new compartments and heat storage bodies in this water tank.

Therefore, maintenance and cleaning after use are extremely simple, and cleaning can be completed in a short time. Further, since the partition body is made of porcelain, it has a high heat insulating ability, does not release wasteful heat from the inside of the partition body to the outside, and is extremely efficient in evaporating water. Further, since the partition body can be easily destroyed by a hammer or the like, it is possible to simply dispose of the partition body or the like after use without requiring special treatment.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

In the present embodiment, the urine processing apparatus 1 for evaporating and diffusing the water of urine excreted from the human body will be described as a specific embodiment.

A cylindrical closed deodorizer 14 is housed in the deodorant section 4, and the deodorizer 14 and the lid 12 are connected to each other by a pipe.
Conducted by 15.

Further, FIG. 3 illustrates in detail the internal configuration of the urine processing apparatus 1 in FIG.

A trap 21 is attached to the inside of the injecting pipe 11, and only the urine injected by the trap 21 flows into the inside to prevent odor and the like from flowing back. And, an upper side is opened on the lower surface of the disk-shaped lid body 12,
An outer case 13 formed of a cylindrical thin steel plate whose inside is sealed is closely attached. A water tank 22 made of metal is housed inside the outer case 13, and the periphery of the upper end of the water tank 22 is airtightly adhered to the lower surface of the lid body 12 by a packing 23. Further, between the bottom of the outer case 13 and the lower surface of the water tank 22, legs 24 for holding the space between the two are installed.

A block 25 is provided on the inner bottom surface of the water tank 22, and a ring-shaped pedestal 26 is fixed to the upper surfaces of the plurality of blocks 25. Then, a cylindrical partition 27 formed of porcelain such as ceramic is fitted to the pedestal 26, and the partition 26 divides the internal space of the water tank 22 into two halves substantially at the center of the water tank 22 by the pedestal 26. Is held. Further, the lower end of the partition 27 is a water tank by the block 25.
It is slightly raised from the bottom of 22 and this block 25
Thus, the water in the water tank 22 maintains a space where it can flow between the lower ends of the partitions 27. Further, a cage 28 formed of a wire mesh or the like is attached to the lower end opening of the partition 27.

A socket 29 is fixed to the center of the lid 12, and a coil-shaped heater 30 is attached to the lower portion of the socket 29.
It is inserted so that it is located in the center of the inside. And
With the heater 30 inserted in the partition 27,
A plurality of small spherical heat storage bodies 31 made of a material such as ceramic, porcelain, and stainless are inserted into the internal space of the partition body 27, and the internal space of the partition body 27 is almost filled with the heat storage bodies 31.

Further, an air pump 32 for inserting air from the outside is attached to the upper surface of the lid body 12.
The water supply pipe 33 for discharging the air from is extended downward and is inverted into a U shape near the bottom surface of the water tank 22, and the inverted water supply pipe 33 is then attached to the inner wall of the water tank 22 and the outer periphery of the partition 27. The space is extended upward, and the discharge port 34 is directed toward the opening in the upper part of the partition 27. In addition, a U-shaped bent bottom end of the water supply pipe 33 has a small inlet 35.
Is opened small. And, of the lid 12,
An input port 36 is opened at a position facing the upper end opening of the partition 27, and the input port 36 is normally closed by a cap 37. The connecting pipe 15 is connected to the lid 12 and communicates with the upper space formed by the water tank 22.

Next, the connection pipe 15 communicates with the center of the inside of the deodorizer 14, and the connection pipe 15 is connected to the heating pipe 41 installed in the deodorizer 14. This heating pipe 41
The deodorizer 14 has a shape that hangs vertically downward from the inner ceiling in the center of the deodorizer 14, and has a cylindrical pipe shape in cross section. A reheating heater 42 for reheating the saturated steam is inserted inside the heating pipe 41, and the reheating heater 42 is held by a socket 43 on the ceiling of the deodorizer 14.

The deodorizer 14 has a shape in which the inside is divided into two parts by a heating pipe 41. The inside of the deodorizer 14 is separated from the heating pipe.
A catalyst body 44 formed of platinum, a metal mesh of platinum or the like is inserted between the outer sides of 41. Further, the diffusion pipe 6 is communicated with the ceiling of the deodorizer 14, and a motor 45 and a fan 46 driven by the motor 45 are installed in the dust device 7 provided in the middle of the diffusion pipe 6. ing.

Next, the operation of the urine handling apparatus 1 will be described.

First, by discharging the small water discharged from the human body to the water receiving body 5, the urine collected by the water receiving body 5 passes through the injection pipe 11 and the trap 21 and is stored in the water tank 22. The urine A stored in the water tank 22 is stored until it reaches a predetermined capacity.

When the urine A is stored in a predetermined amount or more, the heater 30 is energized to heat the urine and the heat storage body 31 in the partition 27. When the urine is stored in the water tank 22, the urine A starts to collect from the bottom of the water tank 22 and also penetrates into the internal space of the partition 27 through the slender 28, so that the urine A enters the gap of the heat storage body 31. ing. In this state, the heater 30 is energized to heat the urine A. First, the heat is applied to the urine A of the partition 27.
And the heat storage body 31 will be heated. In this way, the urine A and the heat storage body 31 are heated by the heater 30,
Since it is insulated from the outside by the partition 27, the water tank 22
Only the small volume of the urine A in the compartment 27 is heated and evaporated without heating the other urine A therein.

Further, since the heat storage body 31 is formed of a material that retains heat such as ceramics, the heat storage body 31 absorbs the heat of the heater 30, and the heat storage body 31 itself also radiates the heat from the surface thereof. Since the surface areas of these heat storage bodies 31 are large in total, the heat generated from each heat storage body 31 heats the urine A around the heat storage body 31, so that the heating speed becomes extremely high.

Further, since the space inside the compartment 27 is filled with the heat storage body 31, the storage volume of the urine A retained inside the compartment 27 is small, and the urine of this small volume is heated and evaporated sequentially, so that Due to the large surface area of the heat storage body 31, the evaporation rate of the urine A is extremely high.

At the same time as heating with this heater 30, an air pump
32 is operated and air is supplied to the water supply pipe 33. Then, this air propagates through the water supply pipe 33, is inverted into a U shape in the water tank 22, and is ejected from the discharge port 34 located at the upper opening of the partition 27. When the air passes through the water supply pipe 33, the water suction port 35 is in contact with the urine A stored in the water tank 22, so that the urine A is sucked into the water supply pipe 33 from the suction port 35 and the urine A And air flow intermittently in the water supply pipe 33, and the urine A and air are discharged to the upper space of the partition 27.

FIG. 4 shows a state in which the urine A is sucked up by the water supply pipe 33. Air B on the water supply pipe 33
When urine flows in and passes through the water inlet 35, the urine A in the water tank 22 is in contact with the water inlet 35, so that the urine A is intermittently sucked, and the urine A and the air B are alternately sent. Therefore, the urine A is transported in the form of dumpling like C, D, E, and F in the water supply pipe 33 and sandwiched by the air. Then, the urine A sucked from the water inlet 35 is jetted together with air at the outlet 34 at the upper end of the water supply pipe 33, and the jetted urine A flows downward from the upper portion of the heat storage body 31 to reach each heat storage body. It will contact the surface of 31. Of the heat storage bodies 31 heated by the heater 30, the water tank 22
Since the water surface of the urine A in the inside is lowered and the heat storage body 31 in the upper part which is not in contact with the urine A is already heated by the heater 30, the urine A ejected from the water supply pipe 33 is in the upper heat storage body 31. The surface of the heat storage body 31 is quickly wetted by the heat of the heat storage body 31.

At the same time, the air pump 32 is used to supply water.
Since air from the outside is released from 33, the air in the water tank 22 is connected to the connecting pipe by the pressure of the released air.
Extruded from 15. In the upper space of the sealed water tank 22, saturated water vapor is evaporated by the heat of the heater 30 and is accumulated. The saturated water vapor is discharged to the outside by the air supplied from the water supply pipe 33. For this reason, the saturated steam does not remain in the water tank 22, and the humidity is always kept at the saturated pressure or lower, so that the evaporation of the saturated steam ejected from the inside of the partition 27 can be promoted.

Thus, the saturated steam evaporated by the heater 30 is transferred from the connecting pipe 15 toward the heating pipe 41. Then, when the saturated steam passes through the heating pipe 41, the reheating heater 42 is already energized, and the reheating heater 42 is always heated. Then the aquarium
The saturated steam containing the bad odor from 22 comes into contact with the reheating heater 42, is heated again, and is discharged from below the heating pipe 41. Since the moisture of the urine A evaporated in the water tank 22 contains elements that constitute a bad odor such as ammonia and bromine, the steam containing the bad odor reheats the heater.
It is heated again by 42 and comes into contact with the catalyst body 44. Then, the vapor that has contacted the catalyst body 44 is redox-reduced, whereby the malodor is removed. Since the fan 46 in the dust suction device 7 is rotated by the motor 45,
Since the air inside the deodorizer 14 is constantly sucked by the fan 46, the vapor whose odor is absorbed by the catalyst body 44 is discharged into the air from the diffusion pipe 6.

By this series of operations, only the water content of the urine discharged to the water receiver 5 is evaporated, and the components constituting the malodor are promoted to be oxidized and reduced by the catalyst to be discharged as odorless, thus constituting urine. Most of the water that is released will be diffused into the atmosphere.

By repeating such a cycle, the urine A in the water tank 22 is evaporated many times. While this cycle is repeated, the non-volatile components and residues in the urine A are sequentially accumulated and adhere to the inner wall of the water tank 22, both side surfaces of the partition 27 and the surface of the heat storage body 31. For this reason, the inside of the water tank 22 must be regularly cleaned,
In that case, first, the lid 12 is removed from the outer case 13, the partition 27 is exposed to the outside, and then the partition 27 is divided by a hammer or the like to finely divide the partition 27 and stored inside. The heat storage body 31 is released. The divided division body 27 and the heat storage body 31 are directly discarded as non-combustible waste. Then, only the inner wall of the water tank 22 is cleaned with a jet jet of water or the like to remove the attached residue. By this cleaning work, it is possible to wait for the next evaporation process.

The procedure for assembling the evaporator after the cleaning work will be described with reference to FIG.

First, in FIG. 5, the outer case 13 is placed in a state of being opened upward, and the water tank 22 after cleaning is inserted into the outer case 13 from above. Then, the bottom of the water tank 22 is brought into contact with the leg 24, and the water tank 22 is held by the leg 24.

Then, a new partition 27 is inserted through the upper opening of the water tank 22. FIG. 6 shows immediately before inserting the partition 27, and by fitting the lower surface of this partition 27 to the pedestal 26, the partition 27 is held so as not to move in the water tank 22.

Next, as shown in FIG. 7, the lid 12 with the heater 30 and the water supply pipe 33 suspended is gently inserted from above the opening of the water tank 22. Since the heater 30 and the water supply pipe 33 are already attached to the lid body 12, they are integrated into a water tank.
It can be inserted into 22. And the outer case 13,
After contacting the periphery of the upper end opening in the water tank 22 with the lower surface of the lid body 12, the both are firmly joined by a bolt or the like, and the outer case 1
3, Stand up the water tank 22 and the lid 12 as one body.

Then, as shown in FIG. 8, in the state where the evaporator is assembled, a new heat storage body 31 is dropped from the charging port 36, and the heat storage body 31 is sequentially stacked in the partition body 27 located therebelow.
If a predetermined number of heat storage bodies 31 are inserted, the charging port 36
Is tightly closed with a cap 37, whereby the inside of the water tank 22 is hermetically closed from the outside.

Further, in the above-mentioned embodiment, the partition 27 is formed of a porcelain having a cylindrical shape, but FIG. 9 shows an example of the partition 51 having another shape.

In this partition 51, there is a peripheral wall portion 52 having a cylindrical outer circumference, and a mesh-shaped mesh-shaped cage portion intersecting with the lower opening of the peripheral wall portion 52.
53 are connected. Then, the peripheral wall portion 52 and the babysail portion 53
Means that clay is used as a raw material, is integrally formed by a punching die, etc., and is integrally formed by sintering in a sintering pot.
Therefore, it is not necessary to combine the metallic cage 28 separately from the partition 27 as in the above-described embodiment, and if the partition 51 is used, the cage 53 can be destroyed at the same time with a hammer or the like. The process at the time is extremely simple.

Further, FIG. 10 shows another embodiment of the partition body according to the present invention.

The partition 55 has a peripheral wall portion 56 having a cylindrical shape, and a U-shaped communication groove 57 as a conductive portion is formed at a plurality of locations around the lower portion of the peripheral wall portion 56. And
A mesh-shaped cage portion 58 is fixed to the inside slightly above the lower end of the peripheral wall portion 56. The peripheral wall portion 56, the communication groove 57, and the dam portion 58 are integrally formed by using clay as a raw material, integrally formed by a punching die or the like, and sintered by a sintering pot. Since the communication groove 57 is cut in the lower part of this partition 55, it can be directly placed on the bottom of the water tank 22 without using the block 25 and the pedestal 26 as in the first embodiment, and the partition 55 Piss, water, etc. can flow into the inside. Therefore, the bottom of the water tank 22 does not need to be processed, and the inside of the water tank 22 can be cleaned very easily.

Further, FIG. 11 shows still another embodiment of the present invention.

In this embodiment, an integrated evaporation container 61 is shown. The outer shape of this evaporation container 61 is substantially the same as that of the water tank 22, the lower surface thereof is curved, and a water tank portion 62 that opens upward is formed. The leg 63 is projected downward,
A partition section 64 having a cylindrical shape is connected to the upper portion of 63. And, in the lower part of this partition 64, a net-shaped sushi
65 are formed. Then, the entire evaporation container 61 is formed integrally by, for example, punching out ceramic particles mixed with water by a punching die, drying in the shade, and sintering in a sintering furnace. That is, the water tank 62 and the supporting legs
The partition 63, the partition 64, and the dam portion 65 are integrally formed of porcelain.

When this embodiment is used in a water vaporizer to evaporate urine several times, impurities, sludge and the like adhere to the inner circumference of the water tank portion 62 and the inner and outer circumferences of the partition portion 64. Then, when cleaning, the evaporation container 61 with these non-volatile solid components still attached is pulled out from the outer case 13, and the water tank portion 62 and the partition portion 64 are divided by a hammer or the like to subdivide the entire evaporation container 61. It can be disposable.

〔effect〕

Since the present invention is configured as described above, household waste, urine,
Only the water content of waste water containing water such as industrial waste can be evaporated very easily. Further, in this evaporation process, the water in the compartment is evaporated first, so that the evaporation efficiency is high and the processing time can be extremely shortened. Further, after being used in several cycles, the partition body, the water tank, etc. to which impurities and sludge adhere are made of porcelain, so that it can be disposable and the cleaning operation becomes extremely easy. In addition, since the cleaning work which the worker dislikes can be simplified, the work of the worker can be reduced.
