Summary:The present invention relates to a bag filter and, specifically, to a bag filter capable of maintaining the best filtering efficiency at all times by regularly performing backwashing which is a filter cleaning function while the bag filter is operated, without having to disassemble the filter in order to clean the filter due to a backwashing function. The bag filter in accordance with the present invention comprises: a body (101) having an inlet pipe (107) into which a fluid containing foreign materials is introduced and a drain pipe (122) from which washing water that has cleaned a filter assembly (110) during the backwashing process is discharged; a separator (102) for sealing an upper portion of the body (101); a predetermined number of through holes (103) which are formed on the separator (102) in the shape of a hole; a cylindrical filter net (112) which is fastened to each of the through holes (103) to be projected upward; and a lid (106) which is fastened to an upper portion of the body (101) and protects and seals the filter net (112) by having a discharge pipe (104) from which a fluid having foreign materials filtered out is discharged and a washing water inlet pipe (121) into which washing water for backwashing is introduced. 본 발명은 백 필터에 관한 것으로서 특히 역세기능을 구비함으로써 필터를 세척하기 위하여 분해할 필요 없이 백 필터 운전 중 정기적으로 필터 세척 기능인 역세를 실시함으로써 항상 최상의 필터링 효율을 유지할 수 있는 백 필터에 관한 것이다. 본 발명에 의한 백 필터는 이물질을 포함한 유체가 유입되는 유입관(107)과, 역세과정에서 필터조립체(110)를 세척한 세척수를 배출하는 드레인관(122)이 구비된 몸체(101); 상기 몸체(101)의 상부를 밀폐하는 분리판(102); 상기 분리판(102)에 구멍 형태로 소정 개수 형성된 관통공(103); 상기 각 관통공(103)에 상향 돌출되도록 체결된 통 형태의 필터망(112); 이물질이 걸러진 유체가 배출되는 배출관(104)과, 역세를 위한 세척수가 유입되는 세척수 유입관(121)을 구비하여 상기 몸체(101)의 상부에 체결되어 필터망(112)을 보호하고 밀폐시키는 뚜껑(106);을 포함하여 구성된다.
