Abstract

The invention relates to a reactor vented waste gas purification device and method. The purification device mainly comprises a vented waste gas check device, a gas bag collecting chamber, a high-rate waste gas dilution device and an optical pyrolysis oxidation device, wherein a reactor is connected to the gas bag collecting chamber through the vented waste gas check device, an outlet of the gas bag collecting chamber is connected to the high-rate waste gas dilution device; an outlet of the dilution device is connected to the optical pyrolysis oxidation device; an outlet of the oxidation device is connected to a gas emission outlet. The purification method comprises following steps: reactor vented waste gas is collected to the gas bag collecting chamber; waste gas concentration is reduced by the high-rate waste gas dilution device; gas with low concentration is subjected to optical pyrolysis purification. The reactor vented waste gas purification device and method have the advantages of being high in safety, good in stability, low in cost, high in purification efficiency and free of secondary pollution.

Description

technical field [0001] The invention relates to a purification device and a method, in particular to a purification treatment device and method for exhaust gas from a reaction kettle. Background technique [0002] In the production process of latex synthesis, resin synthesis, pharmaceutical intermediate synthesis, dye synthesis, waste rubber desulfurization, spice synthesis and other industries, reaction kettles are often used to carry out esterification, nitration, polymerization, condensation and other reactions under high temperature and high pressure conditions. , when the reaction process is over, the high-temperature and high-pressure exhaust gas in the reactor needs to be discharged, which is the exhaust gas from the reactor. The waste gas from the venting of the reactor is discontinuous and unorganized, and the exhaust air volume is small, but the emission concentration is high and the fluctuation range is large. The main pollutants come from volatile reactants and ...
