VOCs exhaust definition
VOCs have a wide range of sources and various emission forms. According to its emission source, it can be easily divided into 5 categories. They are divided into five categories: painting waste gas, plastic and plastic waste gas, stereotyped waste gas, chemical organic waste gas and printing waste gas. Various types of exhaust gas have the characteristics of different types of components. In order to achieve a good treatment effect, and stably meet the exhaust emission standards. Different exhaust gas needs to be treated and possibly recycled through different treatment methods according to their physical and chemical characteristics.

From the perspective of exhaust gas treatment methods, it can be divided into two types: removal methods and recovery methods. From the core analysis of the method and process, the removal process is mainly based on the direct reaction and decomposition of component materials. The recycling process is mainly based on the separation of material components and auxiliary recycling processes. In terms of application, the recovery process can effectively target high value-added and recovery value processes. It can recover and reuse some components in the exhaust gas. Considering the results, it not only reduces the emission concentration and volume of the exhaust gas, but also to a certain extent. This reduces the operating cost of the enterprise.
VOCs product framework
Different exhaust gas treatment processes have been proposed and developed separately for the use goals of exhaust gas recovery and treatment devices, but different technologies have different use effects for different concentrations of exhaust gas. Combining the characteristics of this application, Rankun Technology has divided the VOCs tail gas treatment process into corresponding products according to the treatment scope, concentration and process. Make it play its application efficiency in a reasonable application range.
