Description

Description: TECHNICAL FIELD The present invention relates to a urine evaporating apparatus capable of facilitating the treatment of excrement by evaporating water from urine excreted by the human body.

[Conventional technology]

Human waste that is physiologically excreted from the human body is provided with a toilet, which is an independent room in a house or a company, and is treated by either discharging it into sewage by washing it or storing it in a septic tank and then collecting it. It was The installation of such toilets isolated from the surrounding area is indispensable in places where humans live, and is indispensable for maintaining a cultural and hygienic life.

However, when performing entertainment or working outdoors, for example, at a sports day, trade show, gathering, construction site, or other places where a large number of personnel are dispatched, or where there is no house nearby, sanitary sewage should be sanitized. It had to be processed.

In such a case, conventionally, a movable toilet is installed, and most of them have a built-in tank for storing excreted human waste. The human waste excreted from the human body is stored in this tank, and after a certain period of time, the human waste collected is collected and processed by a vacuum car or the like.

The collection of human waste by such a tank method is unsanitary because it produces a foul odor and a source of pathogens, and chemicals were put into the tank to prevent foul odors and pests. However, the effect was not so remarkable and it was unsanitary. Further, the work of collecting the stored human waste has a drawback that it is troublesome due to its characteristics and that the person doing the work is uncomfortable. In the treatment of human waste in such conventional temporary toilets, modernization and hygiene of the treatment system have been demanded.

For this purpose, various methods of treating excrement have been proposed.

As one of them, there is also proposed an evaporative toilet that heats excreted excrement with heat to evaporate only water, which is a major component of the excrement, and eliminates the work of recovering excrement by a vacuum car or the like. (For example, Japanese Patent Application Sho 63 63113269
(See Japanese Patent Laid-Open No. 01-284383) and the like).

In this newly proposed urine treatment device, urine can be heated by the heat of a heater or the like, and vaporized water vapor can be diffused into the atmosphere. It has high thermal efficiency and is discharged at a high temperature. It is extremely hygienic because it contains only water vapor.

Such a urine evaporator can be installed anywhere as long as a heat source is secured, so it can be freely installed, for example, in the mountains, moving transportation, or the rooftop of a building without sewerage facilities. . For this reason, this new evaporation-type urine disposal system can disperse unsanitary human waste in or around high-rise building sites in high-rise buildings, nuclear power plants, and inside or around dust-sensitive semiconductor factories. It has been used extensively in the park.

〔Example〕

 Hereinafter, the present invention will be described based on an embodiment of the drawings.

FIG. 1 shows the appearance of an embodiment of the present invention, which is a flat and horizontally elongated rectangular parallelepiped main body 1,
The main body 1 is composed of a mast portion 2 that is upright in the shape of a triangular pyramid on the upper surface of the rear portion.

Inside the main body 1, a tank 3 and an evaporator 4 connected to the tank 3 are inserted and arranged so as to be divided into right and left. On the front surface of the mast portion 2, a urinal 5 having an elliptical shape and a large opening is fixed at a position slightly higher than the upper surface of the main body 1. A discharge pipe 6 is connected to the lower portion of the urinal 5, and the drain pipe 6 is connected to the tank 3. Further, a joint pipe 7 for guiding the evaporated water is connected to the evaporator 4, and an exhaust fan 8 having a built-in fan is connected to the upper end of the joint pipe 7. A diffusion pipe 9 extending vertically upward is connected to the upper end of the air exhaust device 8, and the diffusion pipe 9 is extended above the upper end of the mast portion 2.

Next, FIG. 2 illustrates the internal structure of the tank 3 and the evaporator 4 in detail.

The tank 3 has a flat shape, and has a rectangular parallelepiped shape whose depth is longer than the height above and below, and the inside is hollow and is sealed from the outside. Also the evaporator 4
Like the tank 3, it also has a rectangular shape with a greater depth than its height, and is sealed from the outside. The lower side surface of the tank 3 and the lower side surface of the evaporator 4 are connected by a communication pipe 11 so that the urine in the tank 3 can flow into the evaporator 4.

Inside the evaporator 4, a rectangular heating element 12 having a smaller volume than the internal space of the evaporator 4 is housed. The heating element 12 is made of a heat-resistant material such as a thin steel plate or stainless steel, and has a hollow inside. In the space between the inner wall of the evaporator 4 and the heating element 12, a large number of small spherical shapes made of a ceramic material such as alumina (aluminum dioxide), pumice stone, unglazed porcelain, or a metal material such as stainless steel are provided. The heat storage bulb 13 is filled without any gap. By filling the inside of the evaporator 4 with the heat storage balls 13, the heating element 12 is held in the center of the inside of the evaporator 4.

In addition, a heater 14 that generates heat by passing electricity is inserted in a coil shape in the center of the inside of the heating element 12, and platinum, a catalyst such as platinum, etc. is made into particles around the heater 14. The catalyst body 15 is filled with the air flow. Further, on the upper surface of the heating element 12, an introducing pipe 16 having a slightly L-shape is provided close to the inner ceiling of the evaporator 4.
Are connected to each other, and the inside of the evaporator 4 and the inside of the heating element 12 are connected by the introduction pipe 16.

A joint pipe 7 is communicated with the upper surface of the heating element 12 at a position opposite to the introduction pipe 16 and the like, and the joint pipe 7 extends upward and penetrates through the upper surface of the evaporator 4 and its upper portion. Is connected to the exhaust fan 8.

Furthermore, FIG. 3 is a sectional view showing the internal structure of the tank 3 and the evaporator 4 in FIG. A urine A is stored in the tank 3, and a fan 18 rotated by a motor 17 is housed in the exhaust fan 8.

Next, the operation of this embodiment will be described.

First, the urine evaporation device is installed, for example, in a place where there is no sewer such as a plaza, a riverbed, or in the mountains, or a work site at a high place of a high-rise building, an inside of a nuclear plant, or the like.

When installed, the lower surface of the main body 1 is brought into contact with the ground or floor so that the mast portion 2 stands up. Then, indoors, power is supplied to this device from the power line. However, in a place where power cannot be supplied, such as a riverbed, for example, a private power generator is installed in the vicinity and the power line of this power generator is connected.

Once installed and ready, wait for processing.
First, a person who intends to use the stool stands on a flat portion at the center of the upper surface of the main body 1 and excretes toward the urinal 5. Urinal 5
The urine excreted in is collected and introduced into the tank 3 through the drainage pipe 6 from the lower part. The urine A is sequentially stored in the tank 3, and is stored up to a certain amount or more. When the urine A is stored in the tank 3, the urine A also flows into the inside of the evaporator 4 through the communication pipe 11, and the water levels of the urine in the tank 3 and the inside of the evaporator 4 are the same. . When a certain amount or more of urine is stored in the tank 3, electricity is supplied from the power source to the heater 14 to cause the heater 14 to generate heat. At the same time, the motor 17 is operated and the fan 18 is rotated, so that air is sucked from the heating element 12 toward the diffusion pipe 9.

First, when the heater 14 generates heat, the heat heats the particulate catalyst bodies 14 and 15 which are filled in the surroundings, and then the heating element 12 as a whole. Then, the heating element 12
The urine A that is in contact with the outer circumference of the boil boils into water vapor,
The upper space inside the upper part of the evaporator 4 will be filled.

Although the urine A is guided into the evaporator 4 through the communication pipe 11, the evaporator 4 is filled with a large number of heat storage bodies 13, and the actual volume of the space surrounded by the evaporator 4 and the heating element 12 is It is getting smaller. Therefore, the amount of urine A that has flowed in is extremely small. Since the small volume of urine A flowing into the gap of the heat storage bulb 13 is heated by the heat from the heating element 12, the heat from the heating element 12 first heats only the small volume of urine A, The rate of heating and evaporation increases.

The heat from the heating element 12 is also transmitted to the heat storage bulb 13,
Since the heat storage sphere 13 retains heat and has a very large surface area as a total area, the urine A around the sphere 13 is heated by the large surface area, so that the heating speed is increased.

At the same time, since the fan 18 is rotating,
The air in 12 is constantly sucked, and the saturated steam filling the inside of the evaporator 4 is sucked into the heating element 12 through the introduction pipe 16 by the flow of this air. As described above, the catalyst body 15 is filled in the heating element 12 in the form of particles, and since the catalyst body 15 has already been heated by the heater 14, saturated steam is generated in the heating element 12. It is heated again. Since the reheated saturated steam comes into contact with the catalyst body 12, components having a bad odor such as ammonia and urea contained in the saturated steam are oxidized by coming into contact with the surface of the catalyst body 15, and the bad smell is removed. It

Then, the saturated steam from which the bad odor has been removed is sucked through the joint pipe 7 and diffused through the exhaust pipe 8 into the diffusion pipe 9
And finally discharged into the atmosphere through the upper opening of the diffusion pipe 9.

When the urine A in the evaporator 4 is sequentially heated and evaporated, the evaporated amount of urine A is sequentially supplied from the tank 3 into the evaporator 4 through the communication pipe 11. When this continuous evaporation continues, the water level of the urine in the tank 3 sequentially drops.

A certain amount or more of urine A evaporates and the water surface falls, and the tank 3
When the urine A in the inside becomes empty or when the remaining amount becomes small, the power supply to the heater 14 is stopped, the operation of the motor 7 is stopped, and the operation of evaporation is completed.

Next, when the urine A is stored in the tank 3 by a predetermined amount or more, the evaporation operation is performed as described above.
By repeating this cycle, the urine evaporator can be continuously used without performing maintenance such as pumping.
