Filtering device for industrial waste gas

The invention provides a filtering device for industrial waste gas, and relates to the technical field of waste gas treatment equipment. The filtering device for the industrial waste gas comprises a connecting rack; a plurality of filtration stands are communicated with the connecting rack; the left and right sides of the inner walls of the filtration stands are fixedly connected with a pluralityof second gas purification devices by means of a plurality of first gas purification devices; a waste gas through pipe is arranged on the side face of the connecting rack. According to the filtering device for the industrial waste gas, the waste gas is introduced from the venting end of one of vent pipes, impurities are attached on a gas filtering net, and the filtered gas is discharged outside from the venting end of the other one of the vent pipes, so that the high efficiency filtration of the waste gas is completed; the waste gas passes through the gas purifying device arranged at the bottommost part, and is sequen
