Description

technical field [0001] The invention belongs to the field of experimental equipment and relates to waste gas treatment equipment, in particular to laboratory inorganic and organic waste gas purification treatment equipment. Background technique [0002] During the experiment, the laboratory usually produces a large amount of organic or inorganic gases, most of which are poisonous and harmful gases. Therefore, it is necessary to purify the laboratory exhaust gas before it can be discharged into the atmosphere. [0003] The laboratory exhaust gas treatment methods that exist in the market include activated carbon adsorption treatment, high-voltage photoelectric treatment, etc. However, these methods have certain disadvantages: activated carbon adsorption treatment method, short filler use time, fast adsorption and saturation time for acid waste gas, frequent replacement of filler, easy pulverization and adhesion when encountering water, high operating cost, and incomplete tre...

AI Technical Summary

Problems solved by technology

However, these methods have certain disadvantages: activated carbon adsorption treatment method, the use time of the filler is short, the adsorption saturation time for acid waste gas is fast, the replacement of the filler is frequent, it is easy to pulverize and stick when it meets water, the operating cost is high, and the treatment is not thorough; In the treatment method, the exhaust gas passes through a high-voltage electric discharge area with more than 10,000 volts, so that harmful gas molecules are ionized and decomposed to generate part of ozone, and then discharged into the atmosphere. This method consumes a lot of power and has high operating costs, and only Can handle about 60% of the gas
