Background
The multistage treatment can effectively improve the efficiency and stability of the exhaust gas purification and can adapt to the exhaust gas purification requirements of different types, concentrations and components. Typically, the multi-stage process includes three stages, pre-processing, main processing, and post-processing.
The pretreatment stage mainly carries out coarse treatment on the waste gas, such as removing large particles, solid matters, liquid drops and the like, so as to prevent the impurities from blocking or damaging subsequent treatment equipment. The pretreatment can also provide better working conditions for subsequent treatment equipment by adjusting parameters such as the temperature, the flow rate, the humidity and the like of the waste gas.
The main treatment stage is the core part of the exhaust gas purification, and mainly adopts various physical, chemical or biological methods to convert harmful substances in the exhaust gas into harmless substances or reduce the concentration of the harmful substances to an acceptable level. For example, common primary treatment devices include activated carbon adsorbers, wet electric precipitators, catalytic oxidizers, and the like.
The post-treatment stage is to carry out final treatment and cleaning on the waste gas so as to ensure that the waste gas emission accords with the relevant environmental protection standard. Post-treatment typically employs physical or chemical stabilization techniques such as cooling, drying, acid-base neutralization, and the like.
Overall, multistage treatment can effectively improve waste gas purification's efficiency and stability, prolongs treatment facility's life, reduces maintenance cost. In addition, the multi-stage treatment is also helpful to realize the goal of zero emission of the waste gas and promote the sustainable development of enterprises, but in the actual waste gas pretreatment stage, large particles, solid matters and liquid drops in the waste gas are complex in the treatment process and complex in operation, and for the technical field of waste gas treatment, the simpler structure means lower cost, so that a multi-stage waste gas purification device is needed to solve the problems.
