These harmful substances cause serious pollution to the environment and also have adverse effects on human health. Therefore, the development and application of the gas purifying filter have important significance.
At present, a few technical schemes of coke oven gas purifying filters exist on the market. One common technical scheme is to use an activated carbon adsorption method. According to the method, coke oven gas passes through an active carbon layer, and harmful substances are adsorbed and purified by utilizing the adsorption of active carbon. However, since the activated carbon needs to be regenerated after being saturated, the harmful substances adsorbed on the activated carbon need to be removed at a high temperature during the regeneration process, which consumes a great deal of energy and resources.
Another technical proposal is to adopt a membrane separation method. The method realizes the separation of harmful substances by using special membrane materials in coke oven gas. The membrane separation method has the advantages of simple operation, low energy consumption and the like, but the selection and design of the membrane are very critical due to the complex components of the coke oven gas.
In addition, there are some technical schemes using a chemical absorbent method and an electrochemical oxidation method, but these methods have problems of slow reaction rate, complicated equipment and the like.
