Abstract

백필터장치에 있어서, 유인통풍기의 부담을 경감함과 동시에 벤튜리관이 위치하는 여과포 상부의 부착더스트의 없애버림을 용이하게 하는 벤튜리관 부착구조 및 운전상항의 변화에 기인하는 여과포의 부상에 의한 미처리가스의 누출을 방지하는 여과포 부착구조를 제공한다.In the bag filter device, untreated due to the change of operation conditions due to the change of the operating conditions and changes in operation conditions of the venturi tube attaching structure, which reduces the burden on the manned blower and facilitates the removal of the attachment dust on the upper side of the filter cloth in which the venturi tube is located. Provide a filter cloth attachment structure to prevent the leakage of gas.

여과실(1)과 청정가스실(4)이 칸막이판(3)으로 칸막이되고 그 칸막이판(3)에 부착된 복수의 여과포(2)가 여과실(1)내에 배치된 백필터장치에 있어서, 여과포내 상부에 설치된 벤튜리관(7)은 그 주변부분에 공극(8)을 갖고 칸막이판(3)에 설치되고 여과포(2)내와 청정가스실(4)이 공극(8) 및 벤튜리관(7) 내를 통하여 연통되어 있고 또 칸막이판(3)의 여과포부착용 개구부(31)를 형성하는 둘레가장자리에 원통형상의 칼러(25)의 상단가장자리부가 부착되고 칼러(25)에는 상하에 소정간격을 사이에 두고 낙하방지용의 돌기체(25a)와 부상방지용의 돌기체(25b)가 안쪽으로 돌기되고 이들 돌기체간에 형성된 오목부(25c)에 여과포(2)의 상단부가 장착되어 이루어진다.In the bag filter apparatus in which the filtration chamber 1 and the clean gas chamber 4 are partitioned by the partition plate 3, and a plurality of filter cloths 2 attached to the partition plate 3 are arranged in the filtration chamber 1, The venturi tube 7 installed in the upper part of the filter cloth has a void 8 at its periphery and is installed in the partition plate 3. The filter gas 2 and the clean gas chamber 4 are provided with the void 8 and the venturi pipe 7. The upper edge portion of the cylindrical collar 25 is attached to the circumferential edge that communicates through the inside and forms the opening 31 for attaching the filter cloth of the partition plate 3, and the collar 25 has a predetermined interval therebetween. The upper end of the filter cloth 2 is attached to the projection 25a for preventing the fall and the projection 25b for preventing the injury from being protruded inward and formed in the recess 25c formed between the projections.
