Abstract

PURPOSE:To prevent leakage of soot, odor, and smoke, by a method wherein, in an incineration volume reduction disposing device for home refuse, a disposing container provided at its bottom with a heater and a protrusion part communicated to a feed port is mounted in an incinerator, and s cleaning catalyst is situated in an exhaust passage between the incinerator and the disposing container. CONSTITUTION:Refuse 6 charged in a refuse disposing container 5 in an incinerator is heated by a heater 3, and is burnt by means of air fed through a feed port 7, a protrusion part 11, and an opening part 12 with the aid of a feed blower 8. In this case, generated odor, steam, and smoke passes a cleaning catalyst 14 located between the outer wall of the container 5 and the inner wall of an incinerator 1 and enters a cleaner 10 through an exhaust port 9. Heating by a cleaning heater 13 and the action of a catalyst 2 are exerted thereon. Since, as noted above, catalyst reaction is applied thereon by the catalyst 14 the temperature of which is increased by means of the heat of the heater 3 and a combustion heat and reheating is applied and the action of a catalyst 2 is exerted thereon, odor, smoke, and steam can be completely prevented from leakage, and the size of a device can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a waste disposal device for incinerating household waste to reduce the amount of waste generated at home.

Conventional technology Conventional garbage processing devices include those that burn garbage with gas, those that crush garbage and dispose of it into the sewer, and those that ferment garbage, but all of them have problems such as odor, degree of weight loss, ease of installation, etc. Therefore, it was unsuitable for general household use.

Therefore, the inventor has devised a garbage disposal device using an electric heater, as shown in FIG. In other words, a processing container 6 having a constricted bottom having a protrusion 11 on the bottom surface is disposed so as to enclose the heater 3 protruding and fixed at the bottom of the combustion furnace 1, and the outer circumferential surface of the protrusion 11 is is provided with a large number of openings 12 for thank you notes.

The 6 pieces of garbage put into the processing container 6 are heated by the heater 3, and as they are dried and incinerated, they slide down the inclined wall surface of the processing container 6 toward the heater 3, and are gradually incinerated and reduced in weight. At times, the necessary air is supplied from the supply air lower at the bottom of the combustion furnace 1 to the opening 1 by a supply air blower 8.
Exhaust gas generated by combustion flows into the processing vessel S through the exhaust port 9, enters the purifier 1o through the exhaust port 9, is heated by the purification heater 13, is purified by the purification catalyst 2 in the purifier 1o, and is discharged. When the treatment was completed, the upper lid 4 of the combustion furnace 1 was opened, the treatment container 6 was taken out, and the ash was discarded.

Problems to be Solved by the Invention In such a conventional configuration, combustion progresses and the oil in the garbage 6 ignites, or the entire body reaches an ignition temperature, resulting in a lack of oxygen and a large amount of soot. occurs in In this case, the soot obstructs the purification of smoke and odor, and the purification catalyst 2 in the purifier 1o cannot completely purify the soot and odor.
The problem was that it was emitted as smoke. In order to prevent this, there is a problem that the purifier 10 inevitably becomes large-scale.

The present invention solves all of these problems, and provides a garbage processing device that can prevent soot, odor, and smoke from leaking outside the machine using a small purifier even if a large amount of soot is generated inside the processing container. The purpose is to

Means for Solving the Problem In order to solve this problem, the present invention provides an exhaust port connected to a purifier on the side of a combustion furnace for reducing waste by incineration, and an air supply port on the bottom. A garbage processing container is installed in the combustion furnace, and has a protrusion formed on the inside of the bottom surface to cover and envelop the heater that protrudes inside, and an opening is provided in the wall of the protrusion, and the protrusion is opened from the air supply port. An air flow path is formed through the opening to the exhaust port, and a purification catalyst for exhaust gas generated during garbage processing is provided between the outer wall of the processing container and the inner wall of the combustion furnace on the upstream side of the exhaust port. It is composed of

For production With this configuration, soot generated inside the processing container.

Smoke and odors are purified by the purification catalyst, which is heated above its functional temperature using heat from the combustion furnace heater and heat from combustion of garbage, but smoke and odors that cannot be completely purified due to soot obstruction are removed inside the purifier. It is decomposed and discharged outside in a smokeless and odorless state.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 3. Note that parts that are the same as those in the conventional configuration are given the same numbers, and detailed explanation thereof will be omitted.

In the figure, a heater 3 is projected from the inner bottom of a combustion furnace 1 having a lid 4 on the top. A processing container 6 that encloses the heater 3 and has a tapered bottom and has a protrusion 11 having an opening 12 on the side surface formed on the bottom is disposed in the combustion furnace 1 . As shown in FIGS. 1 and 2, a purification catalyst 14 is provided in the gap between both sides of the processing container 6 and the inner wall of the combustion furnace 1 above the sloped part of the processing container 6.

The configuration other than the above is the same as the conventional one.

In the above configuration, the garbage 6 is placed in the processing container 1i5 with the lid 4 opened.
When the waste e is put into the container, the lid 4 is closed, and the heater 3 is energized, the waste e is heated through the protrusion 11.

When heated, combustion gradually progresses from the vicinity of the heater 3, but at this time, the air necessary for combustion flows from the air supply blower 8 into the processing volume 2g6 through the opening 12 from the air supply blower 8, and the air generated from the waste 6 is As shown in FIG. 3, the foul odor, steam, and smoke pass through the purification catalyst 14, pass between the lower slope of the processing container 5 and the inner wall of the combustion furnace 1, enter the purifier 1o through the exhaust port 9, and enter the purification heater. 13, and the purifying catalyst 2 in the purifier purifies odor and smoke other than steam.

However, as the combustion progresses, the oil contained in the garbage 6, such as fish and meat, ignites, and when the combustion occurs, an oxygen-deficient state occurs instantaneously. At this time, the processing container 6 has already received heat from the heater 3 and has reached a high temperature, and the purification catalyst 14 between the processing container 6 wall and the inner wall of the combustion furnace 1 has also reached the functional temperature of 300° C. or higher. This soot, smoke, and odor are mainly purified, and the remaining smoke and odor that cannot be purified due to obstruction by the soot enters the purifier 10 through the exhaust gas ci9 through between the lower part of the processing container 5 and the inner wall of the combustion furnace 1. It will be completely purified and discharged outside.

Effects of the Invention As described above, according to the present invention, since the purification catalyst is provided between the outer wall of the processing container and the inner wall of the combustion furnace, the soot generated in the processing container can be purified without being brought into the purifier. This has the effect of reducing the burden on the purifier, making the purifier more compact, and realizing a garbage treatment device that does not leak soot, smoke, or odor.
