Abstract

The invention relates to an integrated treatment system suitable for high-concentration and low-concentration VOCs gas. The integrated treatment system comprises a first pretreatment system, a second retreatment system, an RTO system and a TNV system. A gas inlet of the first pretreatment system is connected with a low-concentration VOCs waste gas inlet pipe, and a gas outlet of the first pretreatment system is communicated with the RTO system. A gas inlet of the second pretreatment system is connected with a low-concentration VOCs waste gas inlet pipe for gas containing polymers and high-concentration AN substances, and a gas outlet of the second pretreatment system is communicated with the TNV system. The TNV system comprises a combustor and a heat exchanger, a gas inlet of the combustor is connected with a high-concentration VOCs waste gas inlet pipe, an outlet of the combustor is communicated with the heat exchanger, and a gas outlet of the heat exchanger is communicated with the RTO system. According to the integrated treatment system, by adopting a multi-thread TNV&RTO integration mode for treatment, the explosion risk of high-concentration VOCs gas treated by traditional RTO is effectively reduced, and the emission cleanliness is improved; and mixed air preheating is performed after TNV, so that the energy loss is systematically reduced.

Description

technical field [0001] The invention relates to the field of exhaust gas treatment systems, in particular to an integrated treatment system suitable for high- and low-concentration VOCs gases. Background technique [0002] Volatile organic compounds (VOC) are an important part of air pollutants, which mainly come from petrochemical, pharmaceutical production, paint decoration, transportation, garbage storage and other processes. VOCs, together with sulfates and nitrates generated by SO2, NOX, etc., will generate haze mainly PM2.5 fine particles under the action of light, which will seriously affect human health. At present, there are mainly absorption methods, direct adsorption methods, adsorption+combustion methods, low-temperature plasma methods, biological methods, etc. for VOCs treatment processes, among which the most widely used is the adsorption+combustion method, which mainly includes catalytic combustion (CO), heat storage Combustion (RTO) and Regenerative Catalyti...
