Abstract

The invention discloses a system for treating organic exhaust gas by adsorptive-catalytic combustion. The system comprises a pretreatment filter which communicates with and sucks the organic exhaust gas, a main adsorption fan which exhausts the adsorbed exhaust gas and a main fixed adsorbent bed which is connected between the pretreatment filter and the main adsorption fan through a pipe and usedfor adsorbing the exhaust gas; the exhaust pipe of the main adsorption fan is connected with a gas monitoring apparatus which is electrically connected with a control device; the entrance of the mainfixed adsorbent bed is connected with a catalytic bed through a main desorption fan via a pipe; the exit of the catalytic bed is connected with the exit of the main fixed adsorbent bed through a pipe; a temperature sensor in electric connection with a control device is arranged in the catalytic bed; and the main fixed adsorbent bed is connected in parallel with an auxiliary fixed adsorbent bed which conducts an alternative adsorptive or catalytic process with the main fixed adsorbent bed. The invention has the advantages of effectively guaranteeing the treatment efficiency of the organic exhaust gas, replacing manual operation with automatic control and effectively improving the production safety degree, the equipment operation reliability and the economy.

Description

technical field [0001] The invention relates to a waste gas treatment technology, in particular to an adsorption-catalytic combustion system for treating organic waste gas by using controlled adsorption and catalysis to make the organic waste gas treatment system more efficient and operate with low energy consumption. Background technique [0002] With the development of the national economy and the increasing industrialization, the environmental pollution caused by industrial production has attracted more and more attention from governments all over the world. In many industrial fields such as machinery manufacturing, electronics, petroleum, chemical, rubber, paint, coating, printing, etc., the production and processing of industrial products produce a large amount of waste gas containing volatile organic compounds (VOC S exhaust gas). These exhaust gases are discharged into the atmosphere without treatment, and under certain conditions, they will form photochemical pollut...
