Safety treatment device for filtering chemical waste gas

According to the technical scheme, the chemical waste gas filtering safety treatment device comprises a treatment cylinder, a filter cylinder, an ash removal mechanism, an ash discharge mechanism and a purification mechanism, an air blower and an exhaust fan are fixedly connected to the outer wall of the treatment cylinder, the ash removal mechanism is used for removing dust on the filter cylinder, the ash discharge mechanism is used for discharging the dust in the treatment cylinder, and the purification mechanism is used for purifying the filter cylinder. The waste gas treatment device has the beneficial effects that waste gas is input into the treatment cylinder through the air blower, the waste gas in the treatment cylinder is conveyed to the purification mechanism through the exhaust fan, solid granular impurities of the waste gas in the treatment cylinder are filtered through the filter cylinder, and in the process, the dust on the filter cylinder is removed through the dust removal mechanism; and the a
