Embodiment 1

[0028] As shown in the figure, the present invention includes a reactor 1, a reactor discharge device 2, a vent waste gas bypass device 3, solenoid valves 4, 7, 9, a vent waste gas bypass device 5, a check valve 6, and an air bag collection chamber 8. , Workshop exhaust gas collecting hood 10, large rate exhaust gas dilution device 11, photo cracking oxidation device 12, fan 13. The top of the reactor 1 is provided with a venting waste gas bypass device 3, the bottom of the reactor is provided with a reactor discharge device 2, and the venting waste gas check device 5 is provided with a check valve 6 in it. The reactor 1 is connected to the airbag collection chamber 8 through the solenoid valve 4, the venting exhaust gas check device 5, and the solenoid valve 7. The airbag collection chamber 8 is connected to the large-rate exhaust gas dilution device through the solenoid valve 9 and the exhaust pipe of the workshop exhaust gas collecting hood 10 11. The air outlet of the large...

Embodiment 2

[0031] Since the photo-cracking oxidation device 12 can be replaced with one or more of a plasma cracking oxidation device, an ozone oxidation deodorizing device, a wet curtain exhaust gas absorption and purification device, and other purification devices, the rest are the same as in Embodiment 1, and will not be omitted here. Elaborate.

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 and treatment device and method for exhaust gas from a reactor vent. Background technique [0002] In the production process of latex synthesis, resin synthesis, pharmaceutical intermediate synthesis, dye synthesis, waste rubber desulfurization, perfume synthesis, etc., reactors are often used for esterification, nitration, polymerization, condensation and other reactions under high temperature and high pressure conditions. After the reaction process is over, the high-temperature, high-pressure waste gas in the reactor needs to be discharged. This waste gas is the exhaust gas from the reactor vent. The exhaust gas discharged from the reactor is discontinuously and unorganized, and the exhaust volume is small, but the emission concentration is high and the fluctuation range is large. The main pollutants come from volatile reactants and volatile substances produced d...
