Embodiment Construction

[0018] refer to figure 1 and figure 2 , the present invention is an environmental waste gas-zero emission cycle treatment system, including a waste gas collection system, a VOC-sulfide adsorption system, a VOC-sulfide desorption system, a spray desulfurization system, a VOC secondary adsorption system, and a VOC secondary desorption system. system, molecular breaking system, catalytic incineration system, tail gas on-line monitoring system, electronic control system and safety system. The tail gas on-line monitoring system is used to judge the concentration of VOC and sulfide in the gas film. It is used to control the air volume of the circulating fan in the waste gas collection system. The VOC-sulfide adsorption system is used to absorb and concentrate harmful substances in the waste gas collection system. The spray desulfurization system and molecular breaking system are used to remove toxic and harmful gases. It is desorbed from the saturated VOC-sulfide adsorbent, and th...

Abstract

An environment exhaust gas zero emission cyclic treatment system is disclosed. The system includes an exhaust gas collection system, a VOC-sulfide adsorption system, a VOC-sulfide desorption system, a spraying desulphurization system, a VOC secondary adsorption system, a VOC secondary desorption system, a molecule breaking system, a catalytic combustion system, a tail gas on-line monitoring system, an electronic control system and a safety system. The tail gas on-line monitoring system is used for controlling air volumes of circulating fans in the exhaust gas collection system. The VOC-sulfide desorption system is used for adsorbing and concentrating harmful compounds in the exhaust gas collection system. The spraying desulphurization system and the molecule breaking system are used for desorbing toxic and harmful gas from a VOC-sulfide adsorbent saturated in adsorption. The catalytic combustion system is used for completely converting desorbed VOCs and foul gas into CO2 and water. Exhaust gas is treated in a cyclic manner until reaching a zero-emission standard. The cyclic treatment system has characteristics of capabilities of being automatic, continuous, reliable and real-time, zero emission and cyclic absorption.

Description

【Technical field】 [0001] The invention relates to the field of waste gas treatment equipment, in particular to an environmental waste gas-zero emission cycle treatment system. 【Background technique】 [0002] Environmental waste gas, especially malodorous gas emission, will bring great pollution to the environment, cause smog, and endanger public health. There are many kinds of environmental waste gas treatment systems, and waste gas treatment can be mainly divided into four categories: [0003] Physical method: The physical method does not change the chemical properties of the odorous substance, but uses a substance to mask and dilute its odor, or transfers the odorous substance from the gas phase to the liquid or solid phase. Common methods include masking, dilution, condensation and adsorption. [0004] Chemical method: The chemical method is to use another substance to chemically react with the malodorous substance, change the chemical structure of the malodorous substan...
