In the treatment of waste gas generated during the production of rubber products, some effective treatment methods have been developed. However, due to different treatment methods, the treatment effects and advantages and disadvantages are also different.
Combustion method has a high treatment efficiency and can handle waste gas with high concentration at one time. However, the process also requires a large amount of fuel consumption and must be continuously carried out, accompanied by the emission of nitrogen oxides, which results in higher costs.
Bio-treatment can handle waste gas with low concentration and has the advantage of low cost. However, its treatment effect is not good for high-concentration waste gas, and it requires a lot of space and a suitable biological environment, which is inconvenient.
Activated carbon adsorption device is economical and widely used, but with the increasing environmental protection inspections in various regions, the equipment is becoming increasingly unable to achieve standard emissions.
Photocatalytic oxidation technology is a treatment process that uses ultraviolet light as a catalyst to oxidize substances in rubber waste gas with air, oxygen, and other oxidants under specific pressure and temperature conditions. Compared with the above two methods, this method has significant advantages. Its treatment efficiency is high, and it does not require higher temperature conditions, and the cost is relatively low. Its disadvantage is that although it has a clear deodorizing effect, it cannot purify the volatile organic waste gas components in rubber waste gas.
Plasma decomposition method, after years of engineering practice experience, has significant effects in controlling volatile organic waste gas. It has significant advantages in terms of space occupation, fuel consumption, and secondary pollutant production. It has strong adaptability to the composition and concentration of waste gas and can efficiently purify smoke, waste gas, and odorous gases generated in the rubber product industry. It has strong applicability to waste gas generated in the rubber product industry.
From the above analysis, it can be seen that in the treatment of waste gas from rubber products, it is not wise to use a single purification technology alone. It is necessary to use multiple treatment methods in combination to most effectively treat waste gas.
