Problems solved by technology

However, during the collection process, it is not easy to control the collection situation, and when the collection device is replaced, the device needs to be suspended, which increases the probability of air pollution and reduces work efficiency
At the same time, due to the large amount of solid impurities in the exhaust gas, such impurities are easy to adhere to the inner cavity of the collection device, which increases the cleaning burden

Abstract

The invention relates to the technical field of chemical processing and discloses a chemical processing exhaust gas collecting device for controlling an inflation condition by means of air pressure change. The device comprises a shell, wherein a compression chamber is fixedly connected to the outer side of the shell. According to an actual using condition, a filter tool is transferred to the compression chamber automatically, so that the filter tool filters exhaust gas in the compression chamber to reduce solid impurities in gas, and therefore, a condition that the cleaning difficulty of a storage device is increased as a result of adsorption effect of the solid impurities is avoided. After treatment, the filter tool is moved out of the compression chamber automatically, so that it is convenient to clean the filter tool. As the filter tool moves, exhaust gas absorbing operation is triggered to absorb exhaust gas automatically. The compressed exhaust gas is filled and collected. By means of air pressure change in the compression chamber, circulating conditions of the exhaust gas in two gas pipes of a collecting chamber are controlled, so that the exhaust gas is added selectively. Moreover, the inflation condition is judged according to a moving condition of a piston, so that it is convenient to treat the inflated collecting chamber.

Description

technical field [0001] The invention relates to the technical field of chemical processing, in particular to a chemical processing waste gas collection device which utilizes changes in air pressure to control inflation. Background technique [0002] Chemical processing refers to the method of corroding metal, glass and other workpieces with chemical reagents in the material industry, or combining corrosion and grinding to obtain a certain shape, size and surface finish. During the production or chemical processing of these chemical reagents, a large amount of waste gas will be generated. In order to avoid the direct discharge of waste gas to pollute the air and reduce the air quality, it is usually necessary to collect and treat these waste gases. When the common collection device is in use, it is necessary to compress the exhaust gas to convert it into a high-pressure gas, reduce the space occupied by the exhaust gas, and increase the convenience of its treatment. However,...
