Abstract

The invention relates to a low-temperature heat accumulating type method for treating VOCs gas in a catalytic oxidation manner. The problems that in the prior art, serious potential safety hazards exist, ignition temperature is high, and energy consumption is large are mainly solved. The low-temperature heat accumulating type method for treating VOCs gas in the catalytic oxidation manner is adopted, VOCs gas passes through a VOCs high-concentration recovery device and then enters a pre-treatment system, and pretreated gas enters a heat exchanger cold stroke through a fan; gas at an outlet of the heat exchanger cold stroke enters a heating chamber, and gas heated by the heating chamber enters a low-temperature catalytic oxidation bed, a high-temperature catalytic oxidation bed and a honeycomb ceramic heat accumulator; and gas at an outlet of the honeycomb ceramic heat accumulator enters a heat exchanger heat stroke, and gas at an outlet of the heat exchanger heat stroke enters a chimney. According to the technical scheme, an online concentration analysis system is connected with an inlet pipeline of the pre-treatment system, a fan outlet pipeline and an outlet pipeline of the heat exchanger hot stroke, so that the problems are solved well, and the method can be used for treating VOCs gas.

Description

technical field [0001] The invention relates to a low-temperature regenerative catalytic oxidation method for treating VOCs gas. Background technique [0002] At present, there are two main types of treatment technologies for volatile organic compounds (VOCs): one is recovery technology, and the other is destruction technology. Recovery technology is a method of enriching and separating organic gas phase pollutants through physical methods, such as changing temperature and pressure or using selective adsorbents and selective permeable membranes, mainly including adsorption technology, absorption technology, condensation technology and membrane separation technology . The destruction technology mainly uses heat, light, catalysts and microorganisms to convert organic compounds into non-toxic or low-toxic inorganic small molecule compounds such as carbon dioxide and water through chemical or biochemical projections. Catalytic oxidation, plasma destruction, etc. [0003] The ...
