The degree of clogging can be determined.

상기 용수공급기구는, 외부에서 용수를 공급받아 일정량을 저장하는 용수저장조(21)와, 그 용수저장조(21)에서 상기 분사기(14)로 물을 공급하는 용수공급펌프(23)를 포함하고 있다.The water supply mechanism includes a water storage tank 21 for receiving water from the outside and storing a predetermined amount, and a water supply pump 23 for supplying water from the water storage tank 21 to the injector 14. .

상기 용수저장조(21)는 외부의 용수공급라인(22)을 통해 물을 공급받는 한편, 상기 담체저장조(10)에 분사된 물을 배출시켜 저장하며, 수위를 감지하여 일정량 이상의 물은 외부로 배출시키게 된다.The water storage tank 21 receives water through an external water supply line 22, and discharges and stores water injected into the carrier storage tank 10, and detects a water level to discharge water above a predetermined amount. Let's go.

상기 용수공급펌프(23)는 상기 용수저장조(21)의 물을 상기 담체저장조(10)의 분사기(14)로 공급하여 담체(11)에 수분을 공급하고, 분사된 물은 상기 담체저장조(10)의 배수구(15)를 통해 배출되어 상기 용수저장조(21)로 다시 유입된다.The water supply pump 23 supplies the water of the water storage tank 21 to the injector 14 of the carrier storage tank 10 to supply water to the carrier 11, and the injected water is the carrier storage tank 10. Discharged through the drain port 15 of the) is introduced into the water storage tank 21 again.

상기 폭기관(30)은 봉형 산기관으로 상기 담체저장조(10) 내부에 구비되되, 담체(11)의 아래쪽에 구비되어 기포를 발생시킴으로써 담체(11)에 달라붙어 있는 미생물의 일부를 탈리시키게 된다.The width pipe 30 is a rod-shaped diffuser, which is provided inside the carrier storage tank 10, and is provided below the carrier 11 to generate bubbles to desorb some of the microorganisms attached to the carrier 11. .

즉, 상기 담체저장조(10)의 배수구(15)를 닫고 분사기(14)를 통해 물을 분사시켜 담체(11)가 완전히 물에 잠긴 상태에서 폭기관(30)을 통해 기포를 발생시킴으로써 기포에 의해 미생물이 탈리될 수 있게 된다.That is, by closing the drain port 15 of the carrier storage tank 10 and spraying water through the injector 14 to generate bubbles through the explosion pipe 30 in the state in which the carrier 11 is completely submerged in water by the bubble Microorganisms can be detached.

상기 차압계(50)에서 송출된 전기신호를 제어부(60)에서 판단하여 압력차가 일정치(P0) 이상일 경우에는 상기 담체저장조(10)의 배수구(15)를 닫음으로써 담체저장조(10)의 내부에 물이 채워지게 된다.The control unit 60 determines the electric signal transmitted from the differential pressure gauge 50, and when the pressure difference is greater than a predetermined value P0, by closing the drain port 15 of the carrier storage tank 10, the inside of the carrier storage tank 10 is closed. The water will be filled.

상기 폭기팬(40)은 상기 담체저장조(10)에 일정량의 물이 채워진 상태에서 상기 폭기관(30)에 공기를 공급하게 된다.The aeration fan 40 supplies air to the aeration pipe 30 in a state where a predetermined amount of water is filled in the carrier storage tank 10.

상기 담체저장조(10)의 아래측에 탈리배출구(16)가 형성되어 탈리된 미생물을 외부로 배출시키게 된다.Desorption outlet 16 is formed on the lower side of the carrier storage tank 10 to discharge the desorption microorganisms to the outside.

상기 담체저장조(10) 내부에 폭기로 인해 일정량의 미생물이 탈리되면 폭기운전을 정지하고 탈리된 미생물과 물을 외부로 배출한다.When a certain amount of microorganisms are detached due to aeration inside the carrier storage tank 10, the aeration operation is stopped and the detached microorganisms and water are discharged to the outside.

정상운전 상태로 재가동하여 차압 상태를 확인후 정상 차압이면 담체저장조(10) 내부로 수분을 순환시켜 미생물을 증식시키게 된다.After restarting to the normal operating state and checking the differential pressure state, if the normal differential pressure, the water is circulated in the carrier storage tank 10 to multiply the microorganisms.

본 발명에 따른 바이오필터식 탈취기의 미생물 탈리방법은, 미생물을 증식시키는 담체저장조(10)로 유입되는 가스와 배출되는 가스의 압력차를 측정하는 단계, 측정된 압력차가 일정치(P0) 이상일 경우 담체(11)가 완전히 잠기도록 담체저장조(10)에 물을 채우는 단계, 물에 잠긴 담체(11)의 아래쪽에 공기를 공급하여 담체(11)에서 미생물을 탈리시키는 폭기단계, 폭기에 의해 탈리된 미생물을 담체저장조(10)의 외부로 배출시키는 단계를 포함한다.Microbial desorption method of the biofilter type deodorizer according to the present invention, measuring the pressure difference between the gas flowing into the carrier storage tank 10 for discharging the microorganisms and the discharged gas, the measured pressure difference is a certain value (P0) or more In this case, filling the carrier storage tank 10 so that the carrier 11 is completely submerged, aeration step of desorbing microorganisms from the carrier 11 by supplying air to the bottom of the submerged carrier 11, desorption by aeration Discharging the microorganisms to the outside of the carrier storage tank (10).

상기 압력측정단계는 담체저장조(10)에 연결된 가스유입라인(12)과 가스배출라인(13)의 압력차를 측정하여 담체(11) 기공의 눈막힘 정도를 간접적으로 측정하게 된다.The pressure measuring step indirectly measures the degree of clogging of the pores of the carrier 11 by measuring the pressure difference between the gas inlet line 12 and the gas discharge line 13 connected to the carrier storage tank 10.

측정된 압력차가 일정치(P0) 이상일 경우 담체저장조(10)의 내부에 담체(11)가 완전히 잠기도록 물을 채운 다음, 담체(11)의 아래쪽에서 기포를 발생시켜 담체(11)가 증식하고 있는 미생물의 일부를 탈리시키게 된다.If the measured pressure difference is more than a predetermined value (P0), water is filled in the inside of the carrier storage tank 10 so that the carrier 11 is completely submerged. Then, bubbles are generated under the carrier 11 to propagate the carrier 11. Some of the microorganisms present are desorbed.

일정량의 미생물이 탈리되어 담체(11)의 기공이 확보되면 폭기작용을 정지시킨 후 탈리되어 담체저장조(10)의 바닥에 가라 앉은 미생물을 물과 함께 외부로 배출시킨다.When a certain amount of microorganisms are detached and the pores of the carrier 11 are secured, the aeration is stopped and then detached to discharge the microorganisms that have settled on the bottom of the carrier storage tank 10 together with water.

여기서, 일정량의 미생물을 탈리시켜 담체(11)의 기공이 확보되면 가스유입라인(12)의 압력이 하강하고 가스배출라인(13)의 압력이 상승함으로 인해 줄어든 차압의 폭을 차압계(50)에서 감지하여 제어부(60)에 전기신호를 전달함으로써 의 압력차가 일정치(P0) 이하가 되면 폭기작용을 자동으로 멈추게 하는 것도 가능하다.Here, when a certain amount of microorganisms are removed to secure the pores of the carrier 11, the pressure difference of the gas inlet line 12 decreases and the pressure of the gas discharge line 13 increases, thereby reducing the width of the differential pressure in the differential pressure gauge 50. By detecting and transmitting an electrical signal to the control unit 60, it is also possible to automatically stop the aeration when the pressure difference is less than a certain value (P0).

폭기작용을 정지시킨 후 탈리되어 담체저장조(10)의 바닥에 가라 앉은 미생물을 물과 함께 외부로 배출시킨다.After the aeration is stopped, the microorganisms detached and settled to the bottom of the carrier storage tank 10 are discharged to the outside together with water.

탈리된 미생물을 배출시키는 동안 담체(11)의 상부로 물을 분사하여 탈리된 미생물이 용이하게 배출될 수 있도록 하는 것이 바람직하다.While discharging the desorbed microorganisms, it is preferable to spray water to the upper portion of the carrier 11 so that the desorbed microorganisms can be easily discharged.

이상에서 설명한 바와 같이 본 발명에 따른 바이오필터식 탈취기의 미생물 탈리장치 및 탈리방법에 의하면, 과다 증식된 미생물을 탈리시켜 탈취효율을 정상화시킬 수 있고, 탈취기의 담체에 손상을 주지 않고 미생물을 간편하게 탈리시킬 수 있으며, 탈리작업에 소요되는 시간과 인력을 절감할 수 있는 효과가 있다.As described above, according to the microorganism desorption apparatus and desorption method of the biofilter type deodorizer according to the present invention, the deodorizing efficiency can be normalized by desorption of the overgrown microorganisms, and microorganisms can be removed without damaging the carrier of the deodorizer. Desorption can be easily done, and the time and manpower required for the desorption work can be reduced.
