The invention discloses a deodorization device for industrial waste gas treatment. The device comprises a treatment box body, the inner wall of the treatment box body is fixedly connected with a first baffle plate, a second baffle plate and a mounting groove, the first baffle plate and the second baffle plate are respectively located at two sides of the mounting groove, the inner wall of the mounting groove is fixedly connected with a rotating motor, an output shaft of the rotating motor is fixedly connected with a reciprocating lead screw, the reciprocating lead screw is sleeved with a movable block matched with the reciprocating lead screw, and the end, away from the rotating motor, of the reciprocating lead screw is fixedly connected with a rotating rod. According to the invention, the flowing path of industrial waste gas is changed, the industrial waste gas can be in full contact with the sprayed treatment liquid, the industrial waste gas is prevented from being directly discharged without being treated, the deodorization effect is improved, large-particle dust in the industrial waste gas can be cleaned in advance, the large dust is prevented from being attached to the inner wall of the device to form difficult-to-clean substances after being in contact with the treatment liquid, and sufficient treatment on the industrial waste gas is ensured.
