Abstract

본 발명은 수세수 배수용 호퍼의 배수구 근방에서 역세척수를 분사시켜 배수구를 폐색하고 있는 먼지 등을 제거함으로써, 운전중의 수세수를 원활하게 배수할 수 있는 회전재생식 열교환기에서의 수세수 배수용 호퍼의 먼지 제거 장치를 제공한다. 열전달 요소를 장전한 로터를 수용하는 하우징(1)의 상하에 유체 출입구용 리듀서덕트(4∼7)를 접속하고, 고온 유체측의 리듀서 덕트(6,7)내에 수세척 장치(8)를 배치하며, 하측의 리듀서 덕트(7)의 아랫쪽에 수세수 배수용 호퍼(15)를 접속하고, 이 호퍼(15)의 최하부에 호퍼 배수구(16)와 배수 밸브(17)를 배치하여, 이들 호퍼 배수구(16)와 배수 밸브(17) 사이에 역세척수용 배관(18)을 접속함과 동시에, 이 역세척수용 배관(18)에 역세척 밸브(17)를 설치한다. 또한, 상기 호퍼(15)의 상부에 오버플로우 배수구(20)와 배수 밸브(21)를 배치하며, 이들 오버플로우 배수구(20)와 배수 밸브(21) 사이에 역세척수용 배관(22)을 접속함과 동시에, 이 역세척수용 배관(22)에 역세척 밸브(23)를 설치한다.The present invention provides a flushing water drain in a rotary regenerative heat exchanger capable of smoothly draining the flushing water during operation by spraying backwash water near a drain hole of a flushing water draining hopper to remove the dust blocking the draining hole. Provide a dust removal device of the receiving hopper. The fluid inlet and outlet reducers ducts 4 to 7 are connected to the upper and lower portions of the housing 1 containing the rotors loaded with the heat transfer elements, and the water washing device 8 is disposed in the reducer ducts 6 and 7 on the high temperature fluid side. The hopper 15 for flushing water drainage is connected to the lower side of the lower reducer duct 7, and the hopper drain port 16 and the drain valve 17 are arranged at the bottom of the hopper 15, and these hopper drain holes are provided. The back washing water pipe 18 is connected between the 16 and the drain valve 17, and a back washing valve 17 is provided in the back washing water pipe 18. In addition, an overflow drain port 20 and a drain valve 21 are disposed above the hopper 15, and a backwash water pipe 22 is connected between the overflow drain port 20 and the drain valve 21. At the same time, a backwash valve 23 is provided in the backwash water piping 22.
