Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incinerator for incinerating waste such as household food waste and excrement.

[0002]

2. Description of the Related Art As a device of this type, a special table 2-50
There is a so-called "incinerator with catalyst container" described in No. 0820. In this device, an annular electric heating coil is arranged above the ash pan that collects waste, and when excrement is dropped into the ash pan through the center of the annular electric heating coil,
The annular electric heating coil is caused to generate heat, and this heat incinerates the excrement in the ash pan. The vaporized gas generated by this incineration is sucked into a catalyst provided along the outer periphery of the annular electric heating coil, and the odor is removed by this catalyst before being discharged.

[0003]

By the way, in the above-mentioned conventional apparatus, the catalyst is provided along the outer periphery of the annular electric heating coil, and the catalyst is arranged in parallel with the incinerator comprising the annular electric heating coil and the ash pan. It is configured to. However, in the case of adopting such a configuration in which the catalyst and the incinerator are arranged side by side, if a large catalyst is provided, the installation space will be expanded. Further, when the catalyst is downsized, it is not possible to expect an effect in terms of deodorization.

Therefore, an object of the present invention is to improve the deodorizing ability of vaporized gas generated from waste without expanding the installation space of the apparatus.

[0005]

In order to solve the above-mentioned problems, in the present invention, an incinerator for accumulating waste and incinerating the waste, and a vaporized gas generated in the incinerator are introduced,
An odor absorbing means for deodorizing the vaporized gas and then exhausting the odor is disposed on the upper side of the incinerator.
A path is formed for guiding the vaporized gas in the incinerator from the incinerator to the odor absorbing means.

Further, in the present invention, the odor absorbing means includes a chamber for introducing the vaporized gas from the incinerator,
At least a catalyst that absorbs the odor of the vaporized gas is provided in parallel, and the vaporized gas is discharged toward the inner wall of the chamber of the odor absorbing means and then guided to the catalyst.

[0007]

According to the present invention, since the odor absorbing means is arranged above the incinerator and the odor absorbing means and the incinerator are stacked, the installation space can be reduced. Further, since it is not necessary to downsize the odor absorbing means, the deodorizing ability can be improved.

Further, according to the present invention, the vaporized gas is once discharged toward the inner wall of the odor absorbing means and then guided to the catalyst. Therefore, the vaporized gas is not concentrated and absorbed in a part of the catalyst, and the vaporized gas is absorbed in the entire intake surface of the catalyst. This makes it possible to efficiently deodorize the vaporized gas and prevent the catalyst from being partially consumed.

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

FIG. 1 is a sectional view showing an embodiment of an incinerator according to the present invention, which comprises an incinerator 1 and an odor absorbing unit 2.

The incinerator 1 comprises a pot 3 and a lid 4 for closing the pot 3. As shown in FIG. 2, the pot 3 and the lid 4 have a cylindrical shape and a disc shape, and are assembled by being fitted to each other. Furthermore, a flat plate-shaped mounting plate 5 is provided on the upper surface of the lid 4.
Is placed and the two screws 6 and 6 are screwed into the periphery of the pot 3 via both ends of the mounting plate 5, so that the lid 4 is pressed against the pot 3 and the pot 3 and the lid 4 are sealed.

The shuttle 3 has a narrower inner diameter on the upper side and a wider inner diameter on the lower side. In addition, the side wall of the pot 3 has a filth suction pipe 7
Is inserted, and the filth introduced through the filth suction pipe 7 is collected in the pot 3.

As shown in FIG. 3, a reflector 8 is attached to the lower side of the lid 4, and a ring-shaped heater 9 is attached to the lower side of the reflector 8. The pair of terminals of the heater 9 are projected above the lid 4 via the lid 4 and the reflection plate 8. Further, the thermocouple 10 reaches the inside of the incinerator 1 via the lid 4 and the reflection plate 8, and its terminal projects above the lid 4.

The reflection plate 8 is attached so as to be slightly separated from the lower surface of the lid 4 so that the discharge hole 11 formed on the lower side of the lid 4 is not closed. The discharge hole 11 has a lid 4
It is connected to the discharge chamber 12 formed inside. Further, the sleeve 21 of the odor absorbing unit 2 is inserted into the discharge chamber 12, whereby the odor absorbing unit 2 is connected to the lid 4 as shown in FIG. 4, and the incinerator 1 and the odor absorbing unit 2 are connected. Unify.

On the other hand, in the odor absorbing unit 2, the stainless steel yarn binding portion 22, which is a bundle of stainless steel yarns, the first honeycomb catalyst 23, the heater 24, and the second honeycomb catalyst 25.
Are sequentially arranged. This odor absorbing unit 2 is shown in FIG.
The housing 26 is open at the upper side and the left side as shown in FIG. In this case 26, a pair of U-shaped metal fittings 27,
A pair of L-shaped metal fittings 28, a pair of U-shaped metal fittings 29, and a pair of L-shaped metal fittings 30 are attached to a pair of opposing inner wall surfaces. Here, the stainless thread binding portion 22 is inserted into the groove of each U-shaped metal fitting 27, the first honeycomb catalyst 23 is inserted between each U-shaped metal fitting 27 and each L-shaped metal fitting 28, and each U-shaped metal fitting 29 is inserted. Insert the second honeycomb catalyst 25 between each L-shaped metal fitting 30,
Further, a ring-shaped heater 24 is arranged between the first and second honeycomb catalysts 23 and 25, and a pair of terminals of this heater 24 is externally exposed through a pair of holes 31 provided in the side wall of the housing 26. Make it protrude. Then, the L-shaped metal fitting 32 is attached to the position shown by the arrow A, the flat plate 33 is attached to the upper open portion of the housing 26, and the exhaust fan 34 (see FIG. 1) is attached to the left open portion.
(Shown in FIG. 3) is attached, and thereby the odor absorbing unit 2 is assembled.

Further, an L-shaped bent sleeve 21 is projectingly provided on the lower bottom portion of the casing 26 of the odor unit 2 so as to penetrate the lower bottom portion. The sleeve 21 is located in the chamber 35 between the stainless steel yarn binding portion 22 and the right side wall of the housing 26, and the hole thereof faces the right side wall.

The kettle 3 and the lid 4 are formed, for example, by covering the inner and outer wall surfaces with a stainless plate and filling a heat resistant heat insulating material inside. Further, the odor absorbing unit 2 has, for example, each wall formed of a stainless plate.

A process for incinerating the waste in such a structure will be described.

First, As waste, for example, excrement is introduced into the pot 3 through the waste suction pipe 7 and stored therein.

On the other hand, in the odor absorbing unit 2, the heater 24 is caused to generate heat to heat the stainless yarn binding portion 22, the first and second honeycomb catalysts 23 and 25 until they reach a high temperature. Further, the exhaust fan 34 is operated.

Thereafter, while the temperature inside the incinerator 1 is measured by the thermocouple 10, the heater 9 is caused to generate heat and the temperature inside the incinerator 1 is raised. As a result, the excrement in the pot 3 is boiled and incinerated, and vaporized gas containing water, odor, etc. is generated. This vaporized gas continues to be generated until the excrement in the kettle 3 is completely incinerated, and when completely incinerated, ash remains in the kettle 3.

In this incineration process, the vaporized gas in the incinerator 1 is sucked by the exhaust fan 34 so that the gap between the lid 4 and the reflecting plate 8 → the discharge hole 11 below the lid 4 → the discharge chamber 12 → the odor absorption The chamber 35 of the unit 2 → the stainless yarn binding portion 22 → the first
And the second honeycomb catalysts 23 and 25. Then, this vaporized gas is deodorized by passing through the first and second honeycomb catalysts 23 and 25, and the exhaust gas is exhausted from the exhaust hole 34a of the exhaust fan 34.

Here, the space between the pot 3 and the lid 4 is sealed as described above. Further, since a pump, a valve or the like is interposed in the waste suction pipe 7, the waste suction pipe 7 can be closed. In this case, the incinerator 1 is hermetically closed except for the above-described exhaust path of the vaporized gas, so that the exhaust fan 34 exhausts the gas efficiently. In addition, vaporized gas that has not been deodorized does not leak to cause odor.

Since the heater 9 in the incinerator 1 is arranged immediately above the excrement, the excrement can be efficiently heated. Also, on the upper side of the heater 9,
Reflector 8 that reflects downward radiant heat from the heater 9
Is provided, the excrement is heated more efficiently.

Further, when the vaporized gas in the incinerator 1 passes through the gap between the lid 4 and the reflection plate 8, it is further heated by the heat from the reflection plate 8 to promote vaporization. Therefore, the heat radiated from the heater 9 is used without waste.

On the other hand, in the odor absorbing unit 2, since the stainless steel yarn binding portion 22 is heated to a high temperature, the vaporization of the vaporized gas is promoted again here. In addition, the stainless steel yarn binding portion 22 serves as a filter for removing fine-particle inorganic components contained in the vaporized gas, thereby preventing the first and second honeycomb catalysts 23 and 25 in the subsequent stage from being clogged. .. The first and second honeycomb catalysts 23 and 25 are
Since it is heated to high heat and is sufficiently activated, the odor contained in the vaporized gas is effectively removed, and the exhaust gas is exhausted from the exhaust hole 34a of the exhaust fan 34.

The vaporized gas is guided by the sleeve 21 and discharged from the hole of the sleeve 21 toward the right side wall of the chamber 35. Therefore, the vaporized gas is temporarily stored in the chamber 35, and thereafter, the vaporized gas is guided uniformly over the entire surfaces of the stainless yarn binding portion 22, the first and second honeycomb catalysts 23 and 25. In this case, since the performances of the stainless yarn binding portion 22, the first and second honeycomb catalysts 23 and 25 can be sufficiently exhibited, the deodorizing effect is high. Further, since the entire surfaces of the stainless yarn binding portion 22 and the first and second honeycomb catalysts 23 and 25 are uniformly consumed, the durability as a whole is enhanced.

If, for example, vaporized gas is directly discharged from the hole of the sleeve 21 toward the stainless yarn binding portion 22, the vaporized gas will be discharged from the stainless yarn binding portion 22, the first and second portions.
Since they partially pass through the honeycomb catalysts 23 and 25, these parts are partially consumed, the overall durability is reduced, and the deodorizing effect is also reduced.

As described above, in the apparatus of the above-mentioned embodiment, since the odor absorbing unit 2 is provided on the upper side of the incinerator 1, the installation space of this apparatus is small. That is, as compared with the case where the odor absorbing unit 2 is installed side by side in the incinerator 1, the installation space of the device is small. Further, since it is not necessary to downsize the odor absorbing unit 2 and two honeycomb catalysts can be provided, the deodorizing ability can be improved.

[0030]

As described above, according to the incinerator according to the present invention, since the odor absorbing means and the incinerator are stacked, the number of catalysts and the size of the catalyst are increased in order to improve the deodorizing ability. Even if it is set, the installation space does not expand.

Further, since the vaporized gas is once discharged toward the inner wall of the odor absorbing means and then guided to the catalyst, the vaporized gas is absorbed by the entire intake surface of the catalyst. This makes it possible to efficiently deodorize the vaporized gas and prevent the catalyst from being partially consumed.
