The utility model discloses an acid
tail gas collecting device which comprises a collecting box, the upper surface of the collecting box is movably connected with a top cover, the side surface of the collecting box is fixedly connected with a motor, the output end of the motor is fixedly connected with a rotating shaft, and the side surface of the rotating shaft is fixedly connected with an eccentric roller. A transverse plate is fixedly connected to the side inner wall of the collecting box, a mounting plate is fixedly connected to the side inner wall of the collecting box, through cooperation of a filter screen, a motor, an eccentric roller, a
waste material box, an inserting plate and an
activated carbon plate, the device can block dust in
waste gas, the blocked dust can shift towards one side, and the dust can be prevented from entering the
waste gas through the filter screen, the motor, the eccentric roller, the
waste material box, the inserting plate and the
activated carbon plate. And after being accumulated for a period of time, the
waste gas is discharged into the waste box under the action of the eccentric roller for centralized collection, so that the dust can be cleaned without stopping waste gas conveying and opening the device for operation, the influence on the working progress is avoided, the filter screen can be replaced after being damaged, and the replacement is more convenient under the action of a bolt and a nut.
