The utility model relates to a protection filter equipment of explosive specifically is an explosive acid -proof spatters protection filter equipment of row acid fume. The problem of the security environment that acid filtrating is splashed and the acid fume volatilizees and brings is solved. An explosive acid -proof spatters protection filter equipment of row acid fume, including protection casing and filter two parts, the protection casing top is equipped with acid feed liquid inlet line and acid fume export pipeline, the protection casing below hides port on the filter and just leaves the interval between the two, filter upper portion is the cylinder, the lower part is the cone, place with the joint portion of cone at the cylinder and strain the comb, strain the top of combing and placeacidproof filter bag, to carry out the press seal fixed by lieing in on the filter buckle at port border on acidproof filter bag top, the filter passes through the fixed bolster to be supported, thefixed bolster below is equipped with the wheel, filtrating is derived by cone bottom export pipeline. The utility model has the advantages of reasonable design reliably, can effectively prevent splashing of acid feed liquid and filling of acid fume, simple structure, the convenient just low cost of processing.
