Description

  The present invention relates to a garbage disposal apparatus. More specifically, the present invention relates to a garbage disposal apparatus that can efficiently heat a treatment tank with reduced energy loss. Furthermore, the present invention relates to a garbage disposal apparatus capable of efficiently separating water from a fermentation gas containing a large amount of water and more effectively deodorizing the discharged fermentation gas.

  In a general garbage processing apparatus, garbage (or straw) is processed by decomposing into water and carbon dioxide using microorganisms. In such a processing machine, in order to reduce the amount of processed material, the heat of fermentation generated when the garbage is decomposed into water and carbon dioxide by microorganisms is used, and moisture that accounts for about 80% by weight of the garbage is collected. Try to evaporate. However, in order to sufficiently evaporate the water, the heat of fermentation is usually insufficient, so that the treatment tank (stirring tank) is heated using the heater as a heat source.

  Moreover, although the processed material fermented in the processing tank is suppressed from generating malodor, some odor components remain. For this reason, fermentation gas containing moisture (humidity) and odor components is forcibly circulated using a vacuum fan or the like, and deodorized by passing through a catalyst or adsorbent when discharged to the outside.

However, the conventional garbage processing apparatus as described above has the following problems.
The conventional garbage processing apparatus uses a heater as a heat source for heating the treatment tank, but it is well known that when an electric heater or a gas heater is used as the heater, the heat efficiency is not good. So much of the energy is wasted.

  In other words, conventional garbage processing equipment is originally intended to contribute to the conservation of the global environment by reducing the amount of garbage that is incinerated or landfilled, but on the other hand, energy is wasted in this way. However, it is not preferable as a garbage disposal apparatus.

  Moreover, in the conventional garbage processing apparatus, as described above, when the fermentation gas containing moisture (humidity) and odor components is discharged to the outside, it passes through the catalyst and the adsorbent as it is, so that the moisture contained in the fermentation gas is It easily adheres to the catalyst and adsorbent and hinders the deodorizing function of them. Therefore, it has been difficult to effectively deodorize the discharged fermentation gas.

(Purpose of the invention)
An object of the present invention is to provide a garbage disposal apparatus that can efficiently heat a treatment tank with reduced energy loss.
Another object of the present invention is to more effectively deodorize the fermentation gas released to the atmosphere by removing moisture from the fermentation gas containing a lot of moisture and then sending it to the deodorizer. It is to provide a garbage disposal device that can be used.

(Function)
The operation of the garbage disposal apparatus according to the present invention will be described. Here, the constituent elements used in the description are assigned in correspondence with the reference numerals given to the respective parts in the embodiments described later, and these reference numerals are described in the claims of the utility model registration claims. As in the case of the reference numerals, it is only for easy understanding of the contents, and the meaning of each constituent element is not limited to the above-described parts.

(Operation of the first device)
The garbage put into the treatment tank (2) is stirred by the stirring device (3), and gradually decomposed and fermented by microorganisms (fermenting bacteria). The treatment tank (2) is heated to an appropriate temperature by the heat pipe (4), and the heat from each heat pipe (4) is used for evaporation of moisture contained in the fermented processed product. In addition, the heat pipe (4) can perform a large amount of heat transport between the heat supply side and the discharge side with a small temperature difference, so that the processing tank (2) can be used by efficiently utilizing the amount of heat supplied. Can be heated. The fermentation gas generated in the treatment tank (2) is sent to the deodorizer (74) by the fan device (72), deodorized by this, and then released to the atmosphere.

(Operation of the second device)
The garbage put into the treatment tank (2) is stirred by the stirring device (3), and gradually decomposed and fermented by microorganisms (fermenting bacteria). The treatment tank (2) is heated to an appropriate temperature by the heat pipe (4), and the heat from the heat pipe (4) is used for evaporation of moisture contained in the fermented processed product. In addition, the heat pipe (4) can perform a large amount of heat transport between the heat supply side and the discharge side with a small temperature difference, so that the processing tank (2) can be used by efficiently utilizing the amount of heat supplied. Can be heated.
The fermentation gas generated in the treatment tank (2) is first sent to the moisture removing device (73) by the fan device (72) to remove moisture. The fermentation gas from which moisture has been removed is then sent to the deodorizer (74), where it is deodorized and then released to the atmosphere. Since the moisture is removed by the moisture removal device (73) before the fermentation gas is sent to the deodorizer (74) in this way, the moisture contained in the fermentation gas adheres to the catalyst and the adsorbent as in the past. Thus, the deodorizing function of them can be prevented from being inhibited, and the deodorized fermentation gas discharged can be effectively deodorized.

(Operation of the third device)
Garbage that is crushed by the crusher (6) and put into the treatment tank (2) is stirred by the stirring device (3), and gradually decomposed and fermented by microorganisms (fermenting bacteria). The liquid produced in the crusher (6) is purified by the water purifier (64) and discharged. The treatment tank (2) is heated to an appropriate temperature by the heat pipe (4), and the heat from the heat pipe (4) is used for evaporation of moisture contained in the fermented processed product. In addition, the heat pipe (4) can perform a large amount of heat transport between the heat supply side and the discharge side with a small temperature difference, so that the processing tank (2) can be used by efficiently utilizing the amount of heat supplied. Can be heated.
The fermentation gas generated in the treatment tank (2) is first sent to the moisture removing device (73) by the fan device (72) to remove moisture. The fermentation gas from which moisture has been removed is then sent to the deodorizer (74), where it is deodorized and then released to the atmosphere. Since moisture is removed by the moisture removal device (73) before the fermentation gas is sent to the deodorizer (74), moisture contained in the fermentation gas adheres to the catalyst and adsorbent as in the past. Can inhibit the deodorizing function of the fermentation gas, and can effectively deodorize the fermentation gas discharged.

The present invention has the following effects.
(A) According to the garbage processing apparatus according to the present invention, a heat pipe is used as a heat source for heating the treatment tank, and the heat pipe has a small amount of heat transport between the heat supply side and the discharge side. Since it can carry out by a temperature difference, the amount of heat supplied can be used efficiently and a processing tank can be heated. Thereby, when heating a processing tank, the efficient garbage processing apparatus with little energy consumed wastefully can be provided.

(B) According to the garbage processing apparatus provided with the moisture removing device for removing moisture before deodorizing the fermentation gas, the fermentation gas generated in the treatment tank is first sent to the moisture removing device by the fan device. Moisture is removed and the fermentation gas from which moisture has been removed is then sent to a deodorizer, where it is deodorized and then released to the atmosphere. In other words, since the moisture is removed by the moisture removal device before the fermentation gas is sent to the deodorizer, the moisture contained in the fermentation gas adheres to the catalyst and the adsorbent as in the past, and the deodorizing function they have. Can be prevented, and the exhausted fermentation gas can be effectively deodorized.

The present invention will be described in detail based on the embodiments shown in the drawings.
