The following basic requirements shall be met: the gas and liquid in the waste gas treatment equipment of the granulator shall have the contact area and contact time to be satisfied. Both gas and liquid have strong perturbation, reducing mass transfer resistance and increasing absorption power.
1. The selection of exhaust gas treatment equipment shall be suitable and reliable to lay the foundation for compliance with emissions. Because of the composition of exhaust gas, the quality of processing equipment directly affects the safety of production operations and equipment purification. Therefore, environmental compliance is an important criterion.
2. All the waste gas treatment equipment has different functions, and the waste gas treatment is very targeted. As a result, some exhaust gases contain particulate halogens, heavy metals and other compounds that disrupt and even destroy the treatment equipment. Therefore, these compounds must be thoroughly removed and removed before entering the exhaust gas treatment facility.

3. Electronic control and automatic control are the command center of the exhaust gas treatment engineering system, so the electronic control principle planning should be simple and reliable. Electrical components are safe and reliable should have a good working environment.
4. The exhaust gas is generally flammable, explosive, toxic and harmful gas, and the safety factor is an important criterion in the planning. Therefore, the safety index of volatile organic compounds with high concentration must be lower than 1/4 of the blasting limit. Experienced planners will consider sudden concentration evaporation. If the manufacturer's process formula failure, production line temperature or pressure parameters abnormal, it is necessary to have emergency control and methods.
