다음은 상기와 같이 구성된 본 발명의 작동과정을 설명한다.The following describes the operation process of the present invention configured as described above.
먼저, 분뇨를 저장하고 발효하는 탱크(310)는 진공상태를 유지함이 바람직하며, 도 2 내지 도 4에 도시된 바와 같이, 분뇨 투입부(100)로 투입되는 분뇨는 예열부(200)에서 52~55℃의 온도로 예열된 후에 하나 이상의 투입관(110)을 통해 탱크(310)의 하부로 공급되면서 투입되는 분뇨 량에 따라 격벽(320)에 의해 분실한 제1실(311), 제2실(312) 및 제3실(313)의 상부로 분뇨 수위가 상승한다.First, the tank 310 for storing and fermenting the manure is preferably maintained in a vacuum state, as shown in Figures 2 to 4, the manure that is introduced into the manure inlet 100 is 52 in the preheater 200 After being preheated to a temperature of ˜55 ° C., the first chamber 311 and the second lost by the partition wall 320 according to the amount of manure supplied while being supplied to the lower portion of the tank 310 through one or more input pipes 110. The manure level rises above the chamber 312 and the third chamber 313.
이때, 상기 분뇨는 고온 발효부(300)의 하나 이상의 격벽(320) 상단부나 상부에 위치한 상태에서 제어부(미도시)의 제어에 따라 열원 공급부(340)에서 발생한 열원이 열원 공급라인(341)을 순환하는데, 상기 열원 공급라인(341)을 순환하는 열원은 고온의 유체나 스팀 중 어느 하나이나, 여기서는 고온의 유체가 바람직하다.At this time, the manure is a heat source generated from the heat source supply unit 340 under the control of a control unit (not shown) in the state located at the top or the top of one or more partitions 320 of the high temperature fermentation unit 300, the heat source supply line 341 The heat source for circulating the heat source supply line 341 is either hot fluid or steam, but hot fluid is preferable here.
상기 격벽(320)에는 열원 공급라인(341)이 내장되고, 고온의 유체인 열원에 의해 격벽(320)의 온도가 상승하여 분뇨와 열교환되는 과정을 반복하면서 분뇨의 온도를 상승시키며, 온도가 상승된 분뇨는 대류현상에 의해 탱크(310)내부에서 순환하면서 혼합된다.The partition 320 has a heat source supply line 341 embedded therein, the temperature of the partition 320 is increased by a heat source that is a high-temperature fluid to increase the temperature of the manure while repeating the process of heat exchange with the manure, the temperature rises The collected manure is mixed while circulating inside the tank 310 by convection.
이러한 상태에서 분뇨 이동부(330)의 작동으로 제2실(312)에 위치한 분뇨를 흡입하여 제1실(311)과 제3실(313)로 공급한다. 이때, 상기 제2실(312)에 위치한 분뇨가 제1실(311)과 제3실(313)로 공급되어 혼합됨과 동시에 공급되는 분뇨의 속도에 의해 제1실(311)과 제3실(313)의 내부로 이동하여 각 실의 하부에 위치한 분뇨와도 열교환이 이루어져 분뇨는 균일한 온도를 유지할 수 있게 된다.In this state, the manure moving part 330 sucks the manure located in the second chamber 312 and supplies it to the first chamber 311 and the third chamber 313. At this time, the manure located in the second chamber 312 is supplied to and mixed with the first chamber 311 and the third chamber 313 and at the same time the first chamber 311 and the third chamber ( 313) is moved inside the heat exchange with the manure located in the lower portion of each chamber so that the manure can maintain a uniform temperature.
또한, 상기 제2실(312)의 분뇨가 제1실(311)과 제3실(313)로 공급될 때, 제1실(311)과 제3실(313)에 위치한 분뇨를 이동시켜야 하며, 상기 각 실에 위치한 분뇨는 격벽(320)의 경사진 관통공(321)을 경유하여 제2실(312)로 이동함과 동시에 경사진 관통공(321) 주위에 위치한 제2실(312)의 분뇨는 상기 제2실(312)로 이동하는 제1실(311) 및 제3실(313)의 분뇨에 의해 제2실(312)의 상부로 이동하는 과정을 반복한다.In addition, when the manure of the second room 312 is supplied to the first room 311 and the third room 313, the manure located in the first room 311 and the third room 313 must be moved. The manure located in each chamber moves to the second chamber 312 via the inclined through hole 321 of the partition 320 and at the same time, the second chamber 312 located around the inclined through hole 321. Manure is repeated to move to the upper portion of the second chamber 312 by the manure of the first chamber 311 and the third chamber 313 to move to the second chamber (312).
여기서 상기 관통공(321)은 분뇨의 원활한 흐름을 위치하여 경사지게 관통하는 것이 바람직하다.Here, the through hole 321 preferably penetrates obliquely by positioning a smooth flow of manure.
한편, 상기 제1실(311)과 제3실(313)에 위치한 분뇨를 흡입하여 제2실(312)로 공급할 경우는, 상기 제2실(312)의 분뇨를 제1실(311)과 제3실(313)로 공급하는 경우와 반대이므로 설명을 생략한다.On the other hand, when the manure inhaled in the first chamber 311 and the third chamber 313 is supplied to the second chamber 312, the manure of the second chamber 312 is supplied to the first chamber 311. Since it is the opposite of the case of supplying to the 3rd chamber 313, description is abbreviate | omitted.

상기 생성된 가스에 의해 탱크(310) 내부의 압력이 높아져 일정기압 이상이면 압력개폐부재(510)가 개방되고, 일정기압 이하이면 압력개폐부재(510)를 폐쇄시키는 과정을 반복한다. When the pressure inside the tank 310 is increased due to the generated gas, the pressure opening and closing member 510 is opened when the pressure is higher than or equal to a predetermined pressure, and the pressure closing member 510 is closed when the pressure is lower than or equal to the predetermined pressure.
압력개폐부재(510)를 통해 배출된 상기 가스 중 수증기와 황화수소는 수분제거 및 탈황부(400)를 통해 수증기는 냉각하여 액상으로 변화시켜서 제거하고, 황화수소는 수산화나트륨(NaOH)을 이용한 습식탈황법으로 가성소다와 반응시켜 제거한다.Water vapor and hydrogen sulfide in the gas discharged through the pressure opening and closing member 510 is removed through the water removal and desulfurization unit 400 by cooling the water vapor and changing it into a liquid phase, and hydrogen sulfide is wetted by using sodium hydroxide (NaOH). React with caustic soda to remove.
