Special organic waste gas purification device for pipeline of laboratory ventilation cabinet

Abstract

The invention discloses a special organic waste gas purification device for a pipeline of a laboratory ventilation cabinet. The special organic waste gas purification device comprises a waste gas collection system, a waste gas treatment system and a waste gas emission system which are connected sequentially; the waste gas treatment system consists of an air inlet, a purification cabinet and an air outlet; the air inlet is formed in the left lower side of the purification cabinet and connected with the waste gas collection system, the air outlet is arranged on the right side of the purification cabinet and is connected with the waste gas emission system, the purification cabinet is cuboid and has a hollow interior; a deflector plate, a photocatalytic oxidization module and a honeycomb activated carbon adsorption module are arranged in the purification cabinet; the deflector plate is a one-fourth circularly arc-shaped steel plate with the radius of 130mm, the length of the deflector plate is equal to the depth of the purification cabinet and is fixedly arranged on the inner side of the purification cabinet. The device has a simple and reasonable structure, is easy to process and convenient to use, and can effectively purify various waste gases in a laboratory, thus being wide in application range and low in adsorption cost.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment devices, in particular to a special organic waste gas purification device for laboratory fume hood pipelines. Background technique [0002] With the rapid development of my country's economy and the continuous advancement of science and technology, the scale and number of teaching laboratories and scientific research laboratories are increasing. At the same time, the problem of laboratory pollution is becoming increasingly prominent. Laboratory organic waste gas pollution and industrial and mining enterprise pollution It is different. In the past, due to the loose distribution, small and discontinuous emissions, it did not attract enough attention. In fact, there are various types of laboratory exhaust gas pollution, high concentration, strong toxicity, small emission and great harm, and most laboratories are located in residential and office gathering areas, which are closer to us. Or...
