Abstract

The invention relates to the technical field of waste gas treatment, in particular to a polyimide production waste gas exhaust device which comprises a top cabinet and a lower exhaust pipe. A pipe hole is formed in the top of the top cabinet, and the upper exhaust pipe is in sliding connection with the pipe hole; the side blocks are arranged on the two sides of the rotating plate, and filter holes are formed in the side blocks; the inner cylinder is in sliding connection with the filter holes; the filter element is mounted in the inner cylinder; the driving part is arranged in the side block; the first motor is fixed in the top cabinet, an output shaft of the first motor is connected with the bottom end of the rotating rod, a limiting ring groove is formed in the side surface of the rotating rod, a rotating hole is formed in the center of the rotating plate, and the limiting ring groove is rotationally connected with the rotating hole; the top plate is fixed to the upper exhaust pipe, an end face hole is formed in the top end face of the rotating rod, the screw is rotationally connected with the end face hole, a threaded hole is formed in the top plate, and the screw is in threaded connection with the threaded hole; and the switching part is arranged in the rotating rod. By means of the device, the filter element saturated in adsorption can be rapidly replaced, and production is greatly facilitated.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a waste gas exhaust device for polyimide production. Background technique [0002] Polyimide is one of the organic polymer materials with the best comprehensive performance. Its high temperature resistance is above 400 degrees Celsius, and it is extremely resistant to low temperature and difficult to dissolve into organic solvents. It is finally used in films, coatings, advanced composite materials, etc. , whose reference fields include aviation, aerospace, microelectronics, nanometers, liquid crystals, separation membranes, and laser lights, which belong to polymer materials. In the patent with the application number CN202022253878.X and the patent name of a smelting furnace for polyimide production, it is disclosed that the exhaust gas generated during the melting of polyimide materials is purified by using an air filter module, so that the exhaust gas is discharged...
