Description

TECHNICAL FIELD The present invention relates to an incinerator for kitchen garbage, waste paper, etc. generated at home or in business.

2. Description of the Related Art Conventional food waste disposers include mechanical disposers called mechanical disposers and incinerators that use gas fuel or liquid fuel.

The former is a method of mechanically chopping raw garbage with a blade such as that used in a mixer and treating it by flowing it into sewage.The latter burns the fuel in a burner and incinerates the garbage by the heat of combustion. It is something that will end up.

In addition, as a new proposal, there is also a device in which food waste is put in a food waste processing cabinet equipped with a magnetron and heated by microwave to incinerate.

Problems to be Solved by the Invention However, the conventional food waste processing apparatuses having the above-described configurations have the following problems, respectively.

Although the disposer mechanically finely disposes of garbage, the wastewater still contains a large amount of solids, which causes clogging of the sewer system, which has become a major social problem.

The method of incinerating food waste with fuel has a drawback that the inside of the incinerator is heated to a high temperature and needs to be insulated from the outside, and the size of the device is increased to ensure combustion stability. Moreover, since fire power is used, there is a high risk of fire.

Further, the conventional garbage disposal device equipped with a magnetron has the characteristics of solving the problems of other conventional methods such as sewerage problems, downsizing, and safety, but its structure is still insufficient. In particular, it has a drawback that the odor of exhaust gas is extremely bad.

The present invention has been made to solve the above-mentioned conventional problems, and provides a food waste treatment device that has no sewage problem, is small in size, has excellent safety, and has significantly reduced exhaust gas odor. is there.

Means for Solving the Problems The present invention includes at least a magnetron, an air supply port,
And a garbage disposal having an exhaust gas outlet, a garbage container installed in the garbage disposal, and a catalyst body provided in an exhaust gas passage connected to the exhaust outlet of the garbage disposal. A heat exchanger for exchanging heat between the exhaust gas from the food waste processing warehouse and the supply air, comprising a gas supply device for supplying air into the food waste processing warehouse. This is the configuration of the food waste treatment device installed in the exhaust gas flow path leading to.

Action In the food waste treating apparatus having the above structure, exhaust gas containing a large amount of unburned hydrocarbon compounds generated from food waste during the garbage processing and odor components of incomplete combustion products thereof is discharged from the inside of the warehouse. This exhaust gas is passed through a catalyst body that has been heated and activated in advance by a heater to purify the odorous components. Since a heat exchanger is installed between the food waste treatment cabinet and the catalyst, a large amount of water contained in the exhaust gas is condensed and removed by this heat exchanger and supplied for the food waste treatment. It heats air to smoothly combust food waste. Further, since the exhaust gas given to the catalyst has no water content, the catalytic activity is maintained and the exhaust gas odor can be remarkably reduced.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. In the figure, reference numeral 16 is a garbage disposal, which has the door 13 and in which the garbage container 4 can be freely inserted and taken out. This food waste container 4 has a through hole 12 in its side wall and a microwave absorbing ceramic 5 in its inner bottom, and stores food waste 17. A magnetron 1 is placed on the upper part of the garbage disposal 16.
The microwave is transmitted through the microwave transmitting partition wall 15 to be radiated into the garbage disposal 16 and the microwave diffusing device 14 is installed in the garbage disposal 16. A magnetron cooling fan 18 is provided nearby.

The food waste processing cabinet 16 has an exhaust gas outlet 2 at its upper portion and an air supply port 3 at its lower portion. An exhaust passage passing through the heat exchanger 7 and the catalyst 8 is formed from the exhaust gas outlet 2, and an air supply passage from the blower 6 passing through the heat exchanger 7 is connected to the air supply inlet 3. Then, the drain pipe 10 is led out from the heat exchanger 7, and the drain pot 11
I try to receive water at. A catalyst heater 9 is attached to the catalyst 8.

The heat exchanger 7 has a function of cooling the food waste treatment exhaust gas sent from the exhaust gas outlet 2 and condensing and removing a large amount of water contained in the exhaust gas. At the same time, the heat exchanger 7 is sent by the blower 6. It has a function of heating the incoming food waste processing air and supplying it as hot air into the food waste processing cabinet 16. Then, the condensed water condensed in the heat exchanger 7 is adapted to be accumulated in the drain pot 11 via the drain pipe 10.
Therefore, in the drain pot 11, condensed water is drained from the drain pot 11.
It is removable so that it can be easily discarded when it is full.

The food waste container 4 is preferably formed of a microwave permeable material, and is preferably an inorganic sintered body, a combustion body, or a glass body having a microwave penetration depth of 1 m or more, which has poor microwave permeability. This is because when a raw garbage container is made of a substance (microwave absorber), the container itself is heated to a high temperature by microwaves, and the container is likely to be damaged by rapid heating and rapid cooling applied each time the device is used. When using the above-mentioned microwave permeable container, it is desirable to use the microwave absorbing ceramic 5 in the container. This is because if the magnetron was still operating after the garbage was incinerated,
This is because there is a risk of damaging the magnetron itself if there is no substance that absorbs microwaves in the processing chamber. Further, it is desirable to provide a through hole 12 on the wall of the raw garbage processing container for the stability of raw garbage burning.

Next, the operation of this embodiment will be described. First, raw garbage
From the front door 13, put the garbage container 4 containing 17 into the garbage container.
Place in 16 and install as shown. Next, when the operation switch (not shown) is turned on, the catalyst heating heater 9 is first energized to heat the catalyst 8. When the catalyst body is sufficiently heated to the activation temperature, the blower 6, the magnetron 1, the magnetron cooling fan 18, and the microwave diffusion device start operating.
The garbage 17 contained in the garbage container 4 is the magnetron 1
It absorbs the microwaves generated by and is heated rapidly.
In addition, since the microwave transmitting partition wall 15 is provided between the magnetron 1 and the inside of the garbage disposal 16, the magnetron 1 is protected. The garbage 17 that has absorbed microwaves is first dehydrated by releasing water. The water vapor generated from the garbage is sent to the heat exchanger 7 from the exhaust gas outlet 2 together with the supply air entering from the air supply port 3. In the heat exchanger 7, most of the water contained in the exhaust gas is condensed and removed. The exhaust gas from which water has been removed by the heat exchanger 7 is sent to the catalyst 8, where
The odorous components contained in the exhaust gas are purified and released to the outside air. The above-mentioned dehydrated food waste further absorbs microwaves and is rapidly heated to be partially carbonized. As described above, due to the strong electric field generated by the magnetron 1, the carbonized portion of the food waste is intermittently discharged in the warehouse, and the raw food accumulated in the food waste container 4 by that time. The combustible gas that decomposes dust is ignited by this discharge. Due to the heat of combustion of the combustible gas and microwave irradiation, the garbage continues to burn, and this combustion is continued until it is ashed. The end of the garbage processing is performed by a timer (not shown) set in advance according to the amount of garbage processed. The microwave applied after the garbage processing is absorbed by the microwave absorbing ceramic 5.

By providing the heat exchanger 7 as described above, it is possible to remove the water contained in the exhaust gas, prevent the catalyst 8 from being poisoned by water vapor, and prevent the catalyst activity from decreasing, so that it is released to the outside air. The odor of exhaust gas can be reduced, and in particular, the odor of exhaust gas can be significantly reduced at the early stage of treating garbage containing a large amount of water content in the exhaust gas. At the same time, since the supplied air is also heated, the garbage combustion in the garbage disposal 16 was improved, and the odor itself in the exhaust gas from the exhaust gas outlet could be reduced.

In addition, in the present embodiment, the blower 6 is provided before the air supply port 3, but the present invention is not limited to this. For example, an intake fan is installed after the catalyst 8 and air is sucked in the chamber. May be introduced into.

EFFECTS OF THE INVENTION As is clear from the description of the above embodiments, according to the present invention, the air supplied to the garbage disposal and the exhaust gas from the garbage disposal pass through the heat exchanger, so that the moisture in the exhaust gas is efficient. It is possible to obtain a garbage processing device that can be removed efficiently, the odor of exhaust gas is significantly reduced, there is no problem of sewage, and the size and stability are excellent.
