In the treatment of waste gas from rubber production, effective treatment methods have been formed. However, due to different treatment methods, the effects and advantages and disadvantages of the treatment are different. These methods have certain disadvantages compared with the catalytic oxidation method.
The thermal combustion method has high processing efficiency and can treat the exhaust gas with a large concentration at one time. However, the process also requires a large amount of fuel consumption, and must be carried out continuously, accompanied by the emission of nitrogen oxides, and thus the cost is high.
The biological treatment method can treat the lower concentration of the exhaust gas, and has the advantage of low cost, but is not good in the treatment effect of the high concentration exhaust gas, which requires a large amount of space, and is difficult to obtain in the biological environment, and thus is 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 such as air or oxygen under a specific pressure and temperature condition. Compared with the above two methods, the method has obvious advantages, and the treatment efficiency is high, and the high-concentration exhaust gas can be processed at one time, and high temperature conditions are not required, and the cost is relatively low. The only drawback is that as the process progresses, the exhaust gas contains a variety of particulates that poison the catalyst, reducing the efficiency of the process.
The treatment of catalytic oxidation technology in rubber waste gas is not a single use. In the actual 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.
