The vaporized gas generated by this incineration is sucked into the catalyst provided along the outer circumference of the annular electric heating coil, and the odor is removed by this catalyst before being discharged.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional device, although the catalyst is provided along the outer circumference of the annular electrothermal coil and the heat of the coil is considered to activate the catalyst, in reality, the catalyst is Only a small part of the heat of the coil was received and it was not heated sufficiently. For this reason, the removal of odor by this catalyst was insufficient, and the odor was extremely felt from the vaporized gas discharged.

Therefore, an object of the present invention is to sufficiently remove the odor of vaporized gas generated from waste.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present invention, an annular electric heating coil disposed in the incinerator and a path for inhaling and exhausting the vaporized gas generated in the incinerator are provided. It is composed of a vaporized gas exhaust pipe whose mouth is guided to the inside of the electric heating coil, and an odor removing means which is inserted into an inlet of the vaporized gas exhaust pipe and removes the odor of the vaporized gas.

[0006]

[Action]

 According to this invention, the odor removing means is inserted into the suction port of the vaporized gas exhaust pipe, and the suction port is guided inside the annular electric heating coil. Therefore, the odor removing means is located inside the annular electric heating coil. Here, since the annular electric heating coil heats the inside most, the odor removing means located inside this is efficiently heated and fully activated. Therefore, the odor removing means sufficiently removes the odor of the vaporized gas sucked through the suction port.

【Example】

 Hereinafter, embodiments according to the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view showing an embodiment of an incineration treatment apparatus according to the present invention. The apparatus of this embodiment incinerates urine, which is waste.

In the figure, the incinerator 1 comprises an outer pot 2 and a lid 3 of the outer pot 2, and an inner pot 4 is arranged at the bottom of the outer pot 2. An annular electric heating coil 5 is provided on the inner wall surface of the outer pot 2.

The vaporized gas exhaust pipe 6 penetrates through the lid 3 and is introduced into the incinerator 1, and its suction port 6 a is located inside the annular electric heating coil 5. Three catalysts 7 are inserted in the suction port 6a. The vaporized gas exhaust pipe 6 is externally connected to the bellows pipe 8, and an exhaust fan 9 is attached to the end of the bellows pipe 8.

The waste introduction pipe 11 is introduced into the incinerator 1 through the lid 3, and is connected to the hole 12 a of the upper spray tank 12. A pipe 13 that guides urine is connected to the hole 12b on the right side of the spray tank 12, and the urine guided through the pipe 13 once enters the spray tank 12 and from there, the waste introduction pipe 11 is introduced. It is introduced into the incinerator 1 through the and is stored in the inner pot 4.

An exhaust adjusting plate 14 is fixed to the lower side of the waste introducing pipe 11, and the exhaust adjusting plate 14 has a slight gap with respect to the intake port 6 a of the vaporized gas exhaust pipe 6. It is vacant.

A coil thermocouple 15 and an atmosphere thermocouple 16 penetrate through the side wall of the outer pot 2. The coil thermocouple 15 measures the temperature of the annular electric heating coil 5, and the atmosphere thermocouple 16 measures the temperature of the atmosphere in the incinerator 1.

The outer pot 2 and the lid 3 are cylindrical bodies as shown in FIG. 2, and a flat plate-shaped mounting plate 17 is placed on the upper side of the lid 3 and two screws 18, 18 are attached to the mounting plate 17. The outer pot 2 is pressed against the lid 3 by screwing it into the peripheral edge of the outer pot 2 through both ends of the outer pot 2 and the outer pot 2 and the lid 3 are sealed.

Further, as shown in FIG. 2, an opening 2a is formed in the side wall of the outer pot 2, and the inner pot 4 is put in and taken out through the opening 2a. Further, there is provided a door (not shown) that hermetically closes the opening 2a, and after the inner pot 4 is placed at the bottom of the incinerator 1, the door is closed to hermetically close the opening 2a.

The process for incinerating urine, which is waste, in such a configuration will be described below.

First, while measuring the temperature of the annular electrothermal coil 5 and the temperature of the atmosphere in the incinerator 1 by the coil thermocouple 15 and the atmosphere thermocouple 16, respectively, the annular electrothermal coil 5 is caused to generate heat to be burned. The atmosphere in the furnace 1 is set to a preset preheating temperature. Along with this, each catalyst 7 in the suction port 6a of the vaporized gas exhaust pipe 6 is also heated and activated. That is, the inside of the incinerator 1 and each catalyst 7 are preheated.

After that, urine pumped up by a pump (not shown) is guided to the spray tank 12 through the pipe 13. The urine discharged from the tank 12 reaches the inner pan 4 in the incinerator 1 from the spray tank 12 through the waste introduction pipe 11 and is stored in the inner pan 4. Further, the exhaust fan 9 is operated.

Next, while gradually measuring the temperature of the annular electric heating coil 5 and the temperature of the atmosphere inside the incinerator 1, the heating temperature by the annular electric heating coil 5 is gradually increased to determine the temperature of the atmosphere inside the incinerator 1. When the temperature reaches a preset maximum temperature, heating by the annular electric heating coil 5 is stopped here. At this time, the urine collected in the inner pot 4 is boiled and dried, and further burned to ash.

As the urine is boiled and burned, vaporized gas is generated in the incinerator 1. The vaporized gas is deodorized and exhausted. That is, the vaporized gas is gradually sucked into the suction port 6a through a slight gap between the suction port 6a of the vaporization gas exhaust pipe 6 and the exhaust adjustment plate 14, and the odor is removed by each catalyst 7, and thereafter the odor is removed. It is guided to the exhaust fan 9 through the bellows pipe 8 and is exhausted from the exhaust port 9 a of the exhaust fan 9.

Here, the three catalysts 7 inserted into the suction port 6 a of the vaporized gas exhaust pipe 6 are located inside the annular electric heating coil 5 that is most efficiently heated. Therefore, these catalysts 7 are efficiently heated and activated, and the odor of the vaporized gas can be satisfactorily removed.

Further, since the vaporized gas in the incinerator 1 has to pass through a slight gap between the suction port 6 a of the vaporized gas exhaust pipe 6 and the exhaust adjustment plate 14 before reaching each catalyst 7, a large amount of vaporized gas is required. The vaporized gas is not sent to each catalyst 7 at once, but is gradually introduced to each catalyst 7. Therefore, each catalyst 7 can accept the vaporized gas little by little and reliably remove the odor of the vaporized gas.

Further, the vaporized gas generated in the incinerator 1 is gradually sucked through the slight gap between the suction port 6a of the vaporized gas exhaust pipe 6 and the exhaust adjustment plate 14, so that it is sucked after being generated. Spend time until. During this period, the vaporized gas continues to convect in the incinerator 1 and is heated inside the annular electric heating coil 5 to promote vaporization. When the vaporization of the vaporized gas is promoted in this way, the removal of odor by each catalyst 7 is performed more reliably.

In the above embodiment, in order to gradually guide the vaporized gas in the incinerator 1 to each catalyst 7, a slight gap is provided between the intake port 6 a of the vaporized gas exhaust pipe 6 and the exhaust adjustment plate 14. However, instead of this gap, a disc having a large number of small holes may be covered on the suction inlet 6a of the vaporized gas exhaust pipe 6. In short, the flow rate of vaporized gas may be limited so that a large amount of vaporized gas is not sent to each catalyst 7 at once.

By the way, the incinerator according to the above-mentioned embodiment is used by being housed in a movable urine toilet as shown in FIG. In the figure, four casters 32 are fixed to the square at the bottom of the toilet 31, and the casters 32 enable the toilet 31 to move. A toilet bowl 33 for urination is attached to the front wall of the toilet 31. Further, a shutter (not shown) is housed inside the upper side of the toilet 31, and when the end 34 of the shutter is pulled out, the shutter is moved along a pair of rails 35 provided on both sides of the toilet 31. It is extended, and the front of the toilet 33 is closed.

FIG. 4 shows the internal structure of the toilet 31 shown in FIG. 3 when viewed from the left side. In the figure, a pipe 36 is connected to the lower side of the toilet 33, and the pipe 36 is introduced into a urine storage tank 37 arranged inside the toilet 31. When the urine is discharged to the toilet bowl 33, the urine is guided from the toilet bowl 33 to the urine storage tank 37 through the pipe 36 and is stored there.

The incinerator 1 is placed on a shelf 38 provided inside the toilet 31. The pipe 13 connected to the spray tank 12 of the incinerator 1 is introduced into the urine storage tank 37 and connected to the pump 39 in the urine storage tank 37. When the pump 39 is operated, the urine in the urine tank 37 is pumped up and sent to the spray tank 12 via the pipe 13. The urine discharged from the spray tank 37 is introduced into the incinerator 1 and stored in the inner pot 4 as described above.

FIG. 5 shows the internal structure of the toilet 31 shown in FIG. 3 when viewed from the right side. In the figure, a discharge hole 41 is formed in the right wall of the toilet 31, and the discharge port of the exhaust fan 9 is connected to the discharge hole 41. Therefore, the vaporized gas generated in the incinerator reaches the exhaust fan 9 via the bellows tube 8 and is discharged from the discharge hole 41 on the right side wall of the toilet 31.

A casing 42 is attached to the outer pot 2 of the incinerator 1. Inside the casing 42, a power supply terminal of the annular electric heating coil 5 and a terminal of the coil thermocouple 15 are installed. The terminals of the atmosphere thermocouple 16 are housed. Respective lines are connected to these terminals, and these lines are led out from the housing 42 and connected to the control device 43. The power supply terminal of the pump 39 in the urine storage tank 37 is also connected to the control device 43 via a line. The control device 43 operates the pump 39 and causes the annular electrothermal coil 5 to generate heat on the basis of the respective temperatures detected by the coil thermocouple 15 and the atmosphere thermocouple 16. That is, the control device 43 performs the preheating as described above, sends the urine into the incinerator 1 and stores it in the inner pot 4, and boiles and burns the urine stored in the inner pot 4. Perform a series of processing.

Further, a maintenance management door 44 is provided on the right wall of the toilet 31, and the maintenance management door 44 is opened to perform maintenance management of the control device 43. A heat exhaust fan 45 is attached to the rear wall of the toilet 31. The heat exhaust fan 45 discharges the heat in the toilet 31.

In the above embodiment, the device for incinerating urine is illustrated, but the device is not limited to this, and the device of the present invention is suitable for incinerating various other waste materials. It goes without saying that it can be used.
