BACKGROUND OF THE INVENTION
The present invention relates to a garbage processing apparatus that performs decomposition processing of garbage using the force of microorganisms, and more particularly to a structure of intake and exhaust air in the garbage processing apparatus.
[0002]
[Prior art]
In recent years, garbage containing organic matter and moisture has been decomposed and fermented to the extent that it does not affect the environment using the power of microorganisms, and a garbage treatment apparatus for performing this garbage treatment is known. ing. In this garbage disposal apparatus, a garbage disposal tank is filled with a carrier such as a wood chip called a biochip as a garbage disposal material. Garbage is introduced into the garbage treatment tank from the garbage input port provided in the garbage treatment tank, and the garbage is fermented and decomposed by the action of microorganisms that inhabit the garbage treatment material.
[0003]
In this type of garbage processing equipment, the exhaust from the garbage processing tank contains odors generated by the decomposition of organic matter inside the garbage processing tank, and if this is exhausted as it is, the odors drift around. , May cause deterioration of the surrounding environment. Therefore, conventionally, a heating deodorization unit is arranged in the middle of an exhaust passage through which exhaust from the garbage treatment tank is guided, and is deodorized by the heating deodorization unit and then released to the outside air.
[0004]
[Problems to be solved by the invention]
However, in the conventional method of heating and deodorizing the exhaust from the garbage treatment tank, the temperature of the exhaust discharged to the outside air becomes high. For example, in the case of a catalytic combustion type heating and deodorizing apparatus, it is necessary to set the catalyst outlet temperature to 200 ° C. to 400 ° C. Therefore, there is a problem that the installation place of the garbage disposal apparatus is restricted.
[0005]
The present invention was invented in view of the problems of the above-described conventional example, and the object of the present invention is to reduce the temperature of the exhaust gas released to the outside air while maintaining the deodorizing performance. Exhaust can be performed without restriction on the installation location, and the operating cost can be reduced. Furthermore, the heat radiation of the exhaust discharged to the outside air can be effectively used to reduce the heating load in the heating deodorization section. It is in providing the garbage processing apparatus which can.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention includes a garbage treatment tank 1 that contains a garbage treatment material inhabited by microorganisms and that is stirred together with the garbage to perform a fermentation decomposition treatment. In the garbage processing apparatus that discharges the exhaust gas from the exhaust port 9 of the processing machine body to the outside air after being heated and deodorized by the heating and deodorizing unit 22, the upstream flow path 22a and the downstream flow path 22b are disposed inside the garbage processing tank 1.

Can be appropriately changed, for example, in a case where the liquid crystal is disposed on the entire low temperature side flow path 70b or a part of the outside. Thereby, it becomes possible to control the amount of heat recovered from the high-temperature side flow path 70a recovered in the garbage treatment tank 1, and can easily cope with a state suitable for the temperature of the circulating air.
[0024]
FIG. 9 shows a case where the second heat exchange unit 70 and the entire deodorizing device 24 are accommodated inside the garbage treatment tank 1. Other configurations are the same as those in FIG. 1, and only different points will be described.
