Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention cannot be limited by this.

[0022] The VOCs automatic processing system used for painting operations according to the present invention automatically measures and records the VOCs concentration values ​​in the painting operation area and the front-end and rear-end exhaust gases of the pipelines of the VOCs automatic processing system in real time, and processes and calculates the measured VOCs concentration value data , and by controlling the on-off of the valve in the VOCs automatic treatment system, the control of the exhaust gas treatment cycle is realized.

[0023] When the concentration of VOCs in the exhaust gas in the painting operation area or the VOCs automatic treatment system changes, the VOCs automatic treatment system automatically adjusts and controls the valve to ensure the reliabil...

Abstract

The invention discloses a VOC automatic processing system used for spray painting operation and an optimized adjustment method of VOC processing. The system includes an inlet, a front concentration sensor, a regulating valve, a first switching valve, an adsorbent bed agent catalytic bed, a second switching valve, a back concentration sensor, an outlet and a control module; the VOC automatic processing system automatically measures and records concentration values of VOCs of waste gases in the spray painting operation area and the front end and rear end of a system pipeline in real time, processes and calculates measured VOC concentration value data, and controls opening and closing of the valves in the system to realize control of a waste-gas processing cycle; and when the concentration ofthe VOCs in the waste gases in the spray painting operation area or the VOC automatic processing system changes, the system automatically adjusts and controls the valves to ensure reliability of operation of the VOC automatic processing system. The VOC automatic processing system disclosed in the invention can accurately monitor and control the concentration of the VOCs of the waste gases in realtime, the stability of operation of the VOC processing system is improved, and real-time capability and accuracy of monitoring and rapidity, accuracy and stability of control are realized.

Description

technical field [0001] The invention relates to a waste gas treatment system, in particular to a VOCs automatic treatment system for painting operations and an optimization adjustment method thereof, belonging to the technical field of environmental protection. Background technique [0002] In recent years, with the development of society, a large number of chemical companies have sprung up, but insufficient investment in environmental protection has led to the discharge of a large amount of industrial organic waste gas, which has degraded the quality of the atmospheric environment and brought serious harm to human health. Therefore, it is necessary to strengthen the treatment of organic waste gas . At present, government agencies, local governments and various industries have successively issued a number of policies and standards to help the governance of VOCs, and the requirements for the control of pipeline fluids are also getting higher and higher. Among them, the conce...
