Exhaust gas treatment is also called exhaust gas purification. Exhaust gas treatment refers to the work of pre-treatment of the exhaust gas generated by the needle glass steel purification tower for industrial sites and factory workshops before external discharge to meet the national emission standards. General waste gas treatment includes organic waste gas treatment, dust exhaust gas treatment, acid and alkali waste gas treatment, odor exhaust gas treatment and air sterilization and purification. First, it can effectively remove the organic waste gas such as benzene, toluene, xylene, ethyl acetate, acetone, methyl ethyl ketone, ethanol, acrylic acid, formaldehyde, etc. produced by the factory workshop, hydrogen sulfide, sulfur dioxide, ammonia and other acid and alkali waste gas treatment. Second, it depends on how the industry authorities recommend it. As a recommendation of the industry authorities, the credibility of the recommendation is relatively high. Third, we must look at the principle of waste gas treatment. At present, more exhaust gas treatment methods include activated carbon adsorption, high temperature catalytic combustion, condensation, wet recovery, biological methods, and the like. Fourth, we must look at the success stories. Most companies in the market have many success stories. Fifth, we must look at the brand. Look at the company's reputation and effect matching in the company, whether it is the local government waste gas treatment environmental protection company and other titles. Industrial waste gas treatment equipment is widely used in chemical plants, electronics factories, printing plants, painting workshops, painting plants, food factories, rubber factories, paint factories, petrochemical industries and other places that produce dust, odor and smoke.
