In the treatment of waste gas from rubber production, some effective treatment methods have been formed, but due to different treatment methods, the treatment effects are different from the advantages and disadvantages. These methods have certain advantages compared with the catalytic oxidation methods. insufficient.
The thermal combustion method has high processing efficiency and can treat the exhaust gas with a large concentration at one time, but the treatment process also requires a large amount of fuel consumption, and must be continuously performed, accompanied by the emission of nitrogen oxides, so the cost is high.
The biological treatment method can treat the lower concentration of exhaust gas, and has the advantage of low cost, but the treatment effect of the high concentration exhaust gas is not good, and it takes a lot of space, and the biological environment is difficult to obtain, so it is also inconvenient.
Catalytic oxidation is a treatment process in which a metal material is used as a catalyst to oxidize a substance in a rubber exhaust gas with an oxidant substance such as air or oxygen under a specific pressure and temperature condition, and the method has the above two methods. The obvious advantage is that it has high treatment efficiency, can process higher concentration of exhaust gas at one time, and does not require higher temperature conditions, and the cost is relatively low. The only drawback is that as the treatment progresses, the exhaust gas will contain more The granules poison the catalyst, thereby reducing the efficiency of the treatment.
The treatment of catalytic oxidation technology in rubber waste gas is not a single use. In the actual treatment process, it is necessary to use a variety of treatment methods in combination with the way to effectively treat the exhaust gas.
In the treatment process based on catalytic oxidation technology, the total gas treatment process is to collect and pretreat the exhaust gas first, then condense it, then carry out catalytic oxidation, and finally discharge the exhaust gas in compliance with the standard.
