호퍼(2)에 투입된 음식 쓰레기는 파쇄기(3)에 의해서 작은 조각으로 파쇄되고, 교반조(4)의 내통(4a) 내로 이송된다.The food waste put into the hopper 2 is crushed into small pieces by the crusher 3, and is conveyed into the inner cylinder 4a of the stirring vessel 4.

교반조(4)는 배열회수 보일러(14)에 의해서 가열되고 있고, 상기 내통(4a) 내의 음식 쓰레기는 이 가열과 상기 스크류(4b)에 의한 교반에 의해서 액상화되어, 액화 음식 쓰레기가 된다.The stirring tank 4 is heated by the heat recovery boiler 14, and the food waste in the inner cylinder 4a is liquefied by this heating and stirring by the screw 4b to become a liquefied food waste.

그리고, 그 교반조(4) 내의 액화 음식 쓰레기는 상기 원통(4a)으로부터 그 외주부를 통해서 상승하고, 정량 펌프(5d)에 의해 공급관로(5b)에서 순환관로(5a)로 소정량씩 공급된다.And the liquefied food waste in the stirring tank 4 rises from the said cylinder 4a through the outer peripheral part, and is supplied by the fixed quantity pump 5d from the supply line 5b to the circulation line 5a by predetermined amount. .

제 1 차 메탄 발효조(6a) 내에는 주사위 형상의 SL재가 부착된 메탄 발효균이 개재되어 있고, 그 제 1 차 메탄 발효조(6a) 내의 액화 음식 쓰레기는 순환관로(5a) 내를 순환하면서 가열기(5)에 의해 가온되면서, 상기 메탄 발효균에 의해 유기물을 분해하여 약 10시간의 체류시간으로 메탄발효를 수행한다.The primary methane fermentation tank 6a is interposed with a methane fermentation bacterium with an SL-shaped SL material, and the liquefied food waste in the primary methane fermentation tank 6a is circulated in the circulation conduit 5a while the heater 5 While warming by), the organic matter is decomposed by the methane fermentation bacteria and methane fermentation is performed with a residence time of about 10 hours.

여기서, 상기 순환관로(5a)에서의 순환에 의해 메탄 발효균과 유기물이 강제적으로 접촉하고, 더구나 상기 제 1 차 메탄 발효조(6a) 내에 있어서 SL재의 표면에 메탄 발효균이 부착하게 되므로, 균 농도가 상당히 높아지게 되어, 발효가 현격하게 진행된다.Here, the methane fermentation bacteria and the organic substance are forcibly contacted by circulation in the circulation conduit 5a, and furthermore, the methane fermentation bacteria adhere to the surface of the SL material in the primary methane fermentation tank 6a. As a result, fermentation proceeds significantly.

계속해서, 그 액화 음식 쓰레기는 제 2 차 메탄 발효조(6b)로 이송되고, 그 제 2 차 메탄 발효조(6b) 내의 SL재와 메탄 발효균에 의해, 약 6시간의 체류시간으로 메탄 발효를 수행한다.Subsequently, the liquefied food waste is transferred to the secondary methane fermentation tank 6b, and methane fermentation is carried out with a residence time of about 6 hours by the SL material and the methane fermentation bacteria in the secondary methane fermentation tank 6b. .

그리고, 그 제 2 차 메탄 발효조(6b)에 있어서도, SL재의 표면에 메탄 발효균이 부착하게 되므로, 균 농도가 상당히 높아지게 되어, 발효가 현격하게 진행된다.Also in the secondary methane fermentation tank 6b, since the methane fermentation bacteria adhere to the surface of the SL material, the bacterial concentration becomes considerably high, and the fermentation proceeds significantly.

이들 메탄 발효조(6a, 6b)에서 발생한 메탄가스는 메탄가스 포착수단(10)을 통해서 탈황되고, 가스탱크(11)로 수집된다.Methane gas generated in these methane fermentation tanks 6a and 6b is desulfurized through the methane gas trapping means 10 and collected in the gas tank 11.

또, 상기 제 2 차 메탄 발효조(6b)에서 남은 발효된 액화 음식 쓰레기(탈리액)는 약 3000ppm 정도의 BOD 부하를 가지고 있고, 이것을 다음 소화 처리조(7)로 이송하여, 잔류 유기물을 미생물에 의해 소화처리한다.The fermented liquefied food waste (desorption liquid) remaining in the secondary methane fermentation tank 6b has a BOD load of about 3000 ppm, which is transferred to the next digestion tank 7 to transfer the remaining organic matter by microorganisms. Extinguish.

소화 처리조(7)는 제 1 처리조(7a)와 제 2 처리조(7b)로 이루어지고, 상기 탈리액을 제 1 처리조(7a)에 보내어 처리하고 있는 동안은 제 2 처리조(7b)는 휴지해 둔다.The fire extinguishing tank 7 consists of the 1st processing tank 7a and the 2nd processing tank 7b, The 2nd processing tank 7b while sending the said desorption liquid to the 1st processing tank 7a for processing. Leave at rest.

제 1 처리조(7a)에 이송된 탈리액 중의 유기물은 그 처리조 내의 SL판(b)에 밀집하여 기생하고 있는 미생물에 의해서 소화되고, 탈리액이 정화된다.The organic matter in the desorption liquid transferred to the first treatment tank 7a is digested by the microorganisms that are concentrated on the SL plate b in the treatment tank and the desorption liquid is purified.

그러나, SL 원판(b)은 기생한 미생물이 너무 증식하게 되면, 미생물의 콜로니가 SL 원판에서 벗겨져서 유실되고, 하류측을 오염시킬 염려가 있으므로, 그 때는 소화 처리조(7)의 작동을 상기 제 1 처리조(7a)에서 제 2 처리조(7b)로 전환하여, 처리를 계속해서 실행할 수 있다.However, the SL disc (b) may cause the colonies of the microorganisms to peel off from the SL disc and be lost if the parasitic microorganisms grow too much, thus contaminating the downstream side. The processing can be continued by switching from the first processing tank 7a to the second processing tank 7b.

또한, 휴지 중의 처리조에서는 기생하고 있는 미생물이 서로 잡아먹어, 그 수를 줄여, 재차 처리가동이 가능한 상태가 된다.In addition, in the treatment tank at rest, parasitic microorganisms eat each other, reduce the number, and come to a state where the treatment operation can be performed again.

이렇게 해서, 정화된 탈리액은 보조 처리조(8)로 이송되고, SL재로 만들어진 매트(8a) 에 의해 추가로 유기물의 잔존이 없는 것으로 한 후, 침전조(9)로 이송된다.In this way, the clarified desorption liquid is conveyed to the auxiliary treatment tank 8, and it is conveyed to the settling tank 9 after making the mat | matte 8a made from SL material no further remain | survive of organic substance.

또한, 상기 메탄가스 탱크(11)의 메탄가스는 가스엔진(12)의 연료가 될 뿐만 아니라, 추가로 가스 정제재(15)에 의해서 정제하여, 이것을 봄베(16) 등에 충전하여 구내 차량(17)의 연료로서 사용할 수도 있다.In addition, the methane gas of the methane gas tank 11 is not only a fuel of the gas engine 12, but is further purified by the gas refining material 15, and filled into the cylinder 16 or the like, and the premises vehicle 17 Can also be used as fuel.

이와 같이, 본 발명의 음식 쓰레기 처리장치는 음식 쓰레기로부터 메탄가스를 고효율로 발생시켜서 이것을 이용할 수 있는 동시에, 오니나 잔사 등의 배출량이 적고, 더구나 연속해서 운전이 가능한 음식 쓰레기 처리장치이다.As described above, the food waste treatment apparatus of the present invention is a food waste treatment apparatus capable of generating methane gas from the food waste with high efficiency and utilizing it, and having low emissions of sludge and residues, and further being able to operate continuously.

또한, 본 실시예에서는 소화 처리조(7)를 제 1 처리조(7a)와 제 2 처리조(7b)로 이루어지는 것으로 하였지만, 이것은 더 많은 다수의 처리조로 이루어지는 것으로 하여, 이것들을 순차 전환하여 사용할 수도 있다.In the present embodiment, the digestion treatment tank 7 is composed of the first treatment tank 7a and the second treatment tank 7b. However, the digestion treatment tank 7 is composed of a larger number of treatment tanks. It may be.
