Tail gas absorption device

Abstract

The utility model relates to the field of mixed exhaust gas treatment, and in particular to an exhaust gas absorption device, including an inner concave absorption box, an absorption mechanism installed inside the inner concave absorption box, and an air intake mechanism. Through the high-density filter screen of the filter plate, some dust and floating objects can be prevented from being sucked into the device. When the device has been in operation for a long time, the dust and floating objects accumulated on the filter plate affect the suction, the fastening bolts on the double-headed flange pipe are unscrewed to make the double-headed flange pipe unfixed, and the rotating frame is connected to the column by rotation. The rotating frame is rotated to exchange the position of the double-headed flange pipe and the electric push rod. Through the sliding connection between the rotating frame and the inner wall of the double-headed flange pipe, the filter plate is taken out for cleaning. At the same time, the electric push rod can be started to drive the cleaning ring to extend into the intake pipe to clean the inner wall of the intake pipe. In this way, not only can the dust and floating objects be prevented from being affected by the mixed exhaust gas being sucked into the device, but also the cleaning of the filter structure and the inside of the pipe is convenient.

Technical Field

[0001] The utility model relates to the field of mixed tail gas treatment, in particular to a tail gas absorption device. Background Art

[0002] The mixed exhaust gas contains a large amount of carbon dioxide and trace amounts of toluene and hydrogen chloride. After the mixed exhaust gas enters the human body through the respiratory tract and skin, it may have an impact on the human body and cause great harm to the human body. In order to avoid excessive emission of mixed exhaust gas, a mixed exhaust gas absorption and treatment device is generally used.

[0003] When the existing mixed exhaust gas absorption and treatment device absorbs the mixed exhaust gas, the mixed exhaust gas is generally pumped into the device through a pipe by a vacuum device, so as to absorb and treat the mixed exhaust gas. When the mixed exhaust gas is absorbed, it is difficult to avoid some dust and floating objects being sucked into the main body of the device along with the mixed exhaust gas. These dust and floating objects are likely to affect the subsequent treatment of the mixed exhaust gas. Utility Model Content
