Description

Exhaust gas treatment device Technical Field The utility model relates to the technical field of waste gas treatment, in particular to waste gas treatment of greasy dirt-containing water vapor, and specifically relates to a waste gas treatment device. Background When the existing exhaust gas processor processes a scene that some water vapor has more oil mist, the oil mist is accumulated in the host machine, so that the service time of the host machine is short, and frequent maintenance and cleaning are needed. Disclosure of utility model The object of the present utility model is to provide an exhaust gas treatment device which aims at the problems existing in the prior art. The utility model aims at solving the problems through the following technical scheme: An exhaust gas treatment device comprises a treatment host and an air inlet pipe and is characterized in that a preposed filter box is arranged at an air inlet of the air inlet pipe, and the preposed filter box can filter particles with a size of more than 5 mu m in exhaust gas. The filter screen plate is arranged in the front filter box, and the filter screen plate adopts a stainless steel wire net. The wire diameter of the stainless steel wire mesh is phi 0.2-0.3 mm. The inner cavity of the front filter box is internally provided with a caulking groove embedded with the filter screen plate, and the opening side of the caulking groove is sealed by a cover plate. The caulking groove is of a structure with a lateral opening, and the filter screen plate is horizontally inserted into the caulking groove from the lateral direction of the front filter box. 2-4 Caulking grooves are arranged in the inner cavity of the front-mounted filter box, and each caulking groove can be correspondingly embedded with a filter screen plate. The cover plate is fixed on the box body of the front filter box, and the cover plate can compress and fix the filter screen plate from the lateral direction. The front filter box is fixedly connected with an air inlet of the air inlet pipe in a sealing way through a connecting flange. Compared with the prior art, the utility model has the following advantages: According to the utility model, the front part of the air inlet of the existing exhaust gas processor is additionally provided with the front filter box, and the front filter box is internally provided with at least one layer of filter screen plate made of the stainless steel wire mesh, so that a plurality of layers can be selectively installed according to actual conditions to preliminarily filter water vapor and oil mist in the exhaust gas, reduce the processing load of a processing host, prolong the service time of the processing host and reduce the maintenance times. Drawings FIG. 1 is a schematic diagram of an exhaust gas treatment device according to the present utility model; fig. 2 is a structural cross-sectional view of the pre-filter box provided by the utility model. Wherein, the device comprises a 1-treatment main machine, a 2-air inlet pipe, a 3-prepositive filter box, a 4-filter screen plate, a 5-connecting flange, a 6-caulking groove and a 7-cover plate.
