이와같이 구성된 본 발명에 따른 건식 석탄가스화기의 슬랙 냉각장치는 다음과 같이 동작한다.The slack cooling device of the dry coal gasifier according to the present invention configured as described above operates as follows.

먼저 석탄가스화기(1)로부터 흘러내린 슬랙이 슬랙 냉각용 물탱크(2)로 떨어져 지니고 있는 열을 물탱크(2)내의 물로 전달함으로써 냉각되게 된다. 그리고 물탱크(2)내의 물로 열을 전달한 슬랙은 응고된 상태로 물탱크(2)의 하부에 형상된 배출구(3)를 통해 연속적으로 또는 간헐적으로 배출되게 되고, 이때 소량의 물이 배출구(3)를 통해 응고된 슬랙과 함께 배출되므로 보충수 공급펌프(5)가 동작하여 배출된 물만큼 물탱크(2) 내부로 물을 보충하게 된다.First, the slag flowing down from the coal gasifier 1 is cooled by transferring the heat that is dropped into the water tank 2 for cooling the slack to the water in the water tank 2. And the slack which transfers heat to the water in the water tank (2) is discharged continuously or intermittently through the outlet (3) formed in the bottom of the water tank (2) in a solidified state, wherein a small amount of water is discharged (3) Since it is discharged along with the solidified slack through) the replenishment water supply pump 5 is operated to replenish the water into the water tank (2) as much as the discharged water.

그리고 물탱크(2)의 온도가 설정치 이상으로 상승되는 경우에도 보충수 공급펌프(5)가 작동하여 물탱크(2) 내의 물(고온의)을 물탱크(2) 상측에 형성된 배출구(4)를 통해 오버플로우 시킴으로써 물탱크의 온도를 낯추게 된다.In addition, even when the temperature of the water tank 2 rises above the set value, the replenishment water supply pump 5 operates to discharge water (high temperature) in the water tank 2 above the water tank 2. By overflowing through the water tank, the temperature is reduced.

그리고 본 발명의 특징에 따라 물탱크(2)의 상측에 형성된 배출구(4)를 통해 배출된 물은 저장탱크(6)에 저장되게 되고, 저장탱크(6)에 저장된 물의 수위가 일정선을 넘게되면 레벨 트랜스미터(10)가 이를 감지하여 콘트롤러(11)로 신호를 보내게되며, 이에 따라 콘트롤러(11)가 콘트롤 밸브(9)를 열어 물을 공급관(7)을 통해 보충수 공급펌프(5)로 보내게 된다. 이때 저장탱크(6)내의 물이 공급관(7)을 통과하는 과정에서 공급관(7)에 설치된 필터(8)에 의해 물에 혼합된 미세한 슬랙입자가 필터링된 상태로 콘트롤 밸브(9)를 거쳐 보충수 공급펌프(5)로 공급되게 된다.And the water discharged through the discharge port 4 formed on the upper side of the water tank 2 in accordance with a feature of the present invention is stored in the storage tank 6, the water level of the water stored in the storage tank 6 exceeds a certain line When the level transmitter 10 detects this and sends a signal to the controller 11, the controller 11 opens the control valve 9 to supply the water to the supplemental water supply pump 5 through the supply pipe 7. Will be sent to. At this time, while the water in the storage tank 6 passes through the supply pipe 7, the fine slack particles mixed with the water by the filter 8 installed in the supply pipe 7 are filtered through the control valve 9. It is supplied to the water supply pump (5).

이상에서 설명한 바와같이 본 발명 건식 석탄가스화기의 슬랙 냉각장치에 의하면, 오버플로우된 물을 종래방식에서와 같이 버리지 않고 물에 혼합된 미세한 슬랙입자를 필터링하여 재사용하도록 되어 있으므로, 공업용수를 절감할 수 있게 되고, 슬랙입자로 인한 환경오염을 방지할 수 있게 된다.As described above, according to the slack cooling device of the dry coal gasifier of the present invention, it is possible to filter and reuse fine slack particles mixed in the water without discarding the overflowed water as in the conventional method, thereby reducing industrial water. It is possible to prevent the environmental pollution caused by the slack particles.
