Abstract
The invention discloses a chemical waste gas treatment system which comprises a condensation separator, a catalytic absorber, acid and alkali washing equipment, a cyclone demister, microwave photoelectric catalytic oxidation equipment, fan equipment and an activated carbon adsorber which are sequentially communicated through a waste gas pipeline; the condensation separator, the catalytic absorber, the acid and alkali washing equipment, the cyclone demister, the microwave photoelectric catalytic oxidation equipment and the fan equipment are jointly connected with a controller. The waste gas is sequentially subjected to condensation separation, catalytic absorption, acid washing and alkali washing, cyclone demisting, microwave photoelectric catalytic oxidation, activated carbon adsorption and other procedures, it is guaranteed that the waste gas meets the environmental protection requirement when exhausted, and the waste gas treatment system also has the advantages of being small in equipment size, low in operation cost and long in service cycle; the system is high in adaptability to the temperature, humidity and pollutant components of waste gas, simple and reliable in operation management, high in practicability and convenient to popularize and popularize.
Description
technical field [0001] The invention relates to the technical field of chemical waste gas treatment, in particular to a chemical waste gas treatment system. Background technique [0002] Chemical waste gas refers to the poisonous and harmful gas discharged from chemical plants in chemical production. Chemical waste gas often contains many types of pollutants, complex physical and chemical properties, and different toxicity, which seriously pollutes the environment and affects human health. [0003] The choice of exhaust gas treatment process is directly related to whether the exhaust gas treatment emission indicators can meet the treatment requirements and its stability, whether the operation management is convenient and reliable, the construction cost, operation cost, floor area size and energy consumption. [0004] Several methods are currently used and their disadvantages, as follows: [0005] 1. Activated carbon adsorption process. The process has the advantages of le...
