生ゴミ処理にかかるコスト上昇の原因となっている。2. Description of the Related Art Generally, garbage disposal methods are roughly classified into incineration treatment methods and mechanical treatment methods. In Japan, garbage disposal is mainly performed by the incineration method. However, in this incineration method, there is a problem that harmful substances such as dioxin are generated depending on incineration conditions. For this reason, the incineration has been improved at a higher incineration temperature than in the prior art so that the thermal decomposition of dioxin is sufficiently performed, but a large amount of incinerated exhaust gas such as carbon dioxide is generated. In addition, the energy consumed for garbage disposal is greatly increased,
It is the cause of the increase in the cost of garbage disposal.

化にしか見出せない。[0003] The mechanical treatment method is classified into three types: carbonization drying treatment, microorganism treatment, and fermentation treatment. Carbonization drying is a method to reduce the volume by heating the garbage to reduce the volume by half-carbonization.However, the equipment can be made compact, but the running cost is high and the exhaust gas is also reduced significantly compared with the incineration method. However, the advantage can be found only in the reduction of the volume of the processed material.

効な生ゴミ処理方法である。[0004] In contrast to these methods, the microbial treatment decomposes garbage with microorganisms, so that the running cost is low, and the products after the decomposition are water, carbon dioxide, residues and the like. be able to. The fermentation treatment is the same as the microorganism treatment in that the treatment is performed using microorganisms, but the products produced after the garbage treatment are different. In particular,
In methane fermentation treatment, methane bacteria generate methane gas,
This is a very effective garbage disposal method because it can be used as fuel.

とが困難であった。However, the conventional garbage disposal apparatus using methane bacteria has a concentration adjusting chamber for adjusting the concentration of a slurry obtained by adding dilution water to finely divided garbage.
Fermentation chambers for methane fermentation by adding methane bacteria to the slurry are arranged side-by-side, and the slurry is transported by a pump and put in from the bottom of the concentration control chamber from above the fermentation chamber. To be limited to a large place with an area where all the components such as concentration adjustment room and fermentation room can be arranged, place where garbage is generated, for example, secure the installation place in the cafeteria in the urban area Was difficult.
【０００６】また、メタン発酵時に悪臭の原因となる硫
化物が発生し、外部へ悪臭が漏れるという虞があった。
このため、この生ゴミ処理装置を住宅地に設置すること
は敬遠されていた。[0006] Further, there is a possibility that sulfides causing malodor are generated during methane fermentation, and the malodor leaks to the outside.
For this reason, installing this garbage disposal apparatus in a residential area has been avoided.

It can be installed even in a small area that was previously difficult to install, and it is easy to prevent stench from leaking out,
It is another object of the present invention to provide a garbage disposal apparatus that can reduce energy consumed during operation of the apparatus.

After the adsorption of methane is completed, the non-adsorbed gas outlet 62 and the valve 39 are closed, the methane gas outlet 61 is opened, and the adsorbent 58 is heated by the heating device 60 attached to the adsorption tank 59. After being desorbed, methane gas is taken out from the methane gas outlet 61.

3. The non-adsorbed gas discharge port 62 opened to the communicating state at 3
When the non-adsorbed gas three-way valve 65 communicates with the adsorption tank 59a, the fermentation gas passes between the adsorbents 58a of the adsorption tank 59a, and methane is adsorbed. Gases other than methane are discharged from the non-adsorbed gas discharge port 62. At the same time, since the other adsorption tank 59b is shut off from the fermentation tank 36 by the three-way valve 63, the adsorbent 58b is heated by the heating device 60b by connecting the adsorption tank 59b and the methane gas outlet 61 with the methane gas three-way valve 64. The methane already adsorbed is desorbed and discharged from the methane gas outlet 61.

ができる。After the amount of methane adsorbed by the adsorbent 58a reaches a saturated state, the three-way valve 63 is switched to shut off the adsorption tank 59a, the fermentation tank 36 and the desulfurizer 38, and the fermentation with the adsorption tank 59b on the desorption operation side. The tank 36 and the desulfurizer 38 are opened. At the same time, the open state between the methane gas outlet 61 and the non-adsorbed gas outlet 62 and each of the adsorption tanks 59a and 59b is switched. By doing so, the adsorbent 58b of the adsorption tank 59b opened to the fermenter 36 starts to adsorb methane,
Adsorption tank 59a isolated from fermentation tank 36 and desulfurizer 38
If the adsorbent 58a is heated, desorption of methane starts.
By repeating this operation intermittently, methane gas can be continuously and efficiently extracted from the methane gas extraction mechanism 40.

According to the first aspect of the present invention, the garbage storage chamber, the concentration adjustment chamber, and the fermentation chamber are formed in order from the top in the processing tower formed in a series in the vertical direction. It is possible to reduce the size of the refuse treatment device, particularly, the size in the front-rear and left-right directions, and to install the methane fermentation treatment type garbage treatment device even in a narrow place where the refuse treatment device could not be disposed conventionally. In addition, since garbage is dropped from above in the processing apparatus to perform the processing, it is not necessary to separately provide a transfer apparatus, so that the structure can be simplified, and the energy required for transfer can be suppressed. it can. And since the upper part of a fermentation room is covered with the bottom of a concentration control room, and a communicating part is closed by an opening-and-closing valve mechanism, it can make it easy to prevent a bad smell generated at the time of methane fermentation from leaking outside. Further, since methane generated in the fermentation chamber can be extracted from the methane gas extraction mechanism, the methane gas can be effectively used as an energy source.
