Low-concentration high-air-volume organic waste gas treatment system and treatment process thereof

Abstract

The invention discloses a low-concentration high-air-volume organic waste gas treatment system and a treatment process thereof, and belongs to the technical field of organic waste gas treatment. The treatment system comprises a fan, a pretreatment system, a concentrating rotary wheel, a heater, a cooler, a membrane separator, a vacuum pump, a condenser and a product tank; and a rotary wheel adsorption concentrating technique, a membrane separation technique and a condensation technique is combined into an integrated process, and low-concentration organic waste gases exhausted during the production of industries such as coating, printing, automobile spray-coating and furniture making are subjected to recovering treatment, so that air pollution is reduced, the energy utilization ratio is increased, and the enterprise cost is reduced.

Description

technical field [0001] The invention relates to the technical field of organic waste gas treatment, in particular to a low-concentration, high-volume organic waste gas treatment system and a treatment process thereof. Background technique [0002] Organic waste gas is the most common type of pollutant emitted by coating, printing, automobile spraying, furniture manufacturing and other industries. With the development of industry and the improvement of productivity, the emission of VOCs is increasing day by day, and has a wide range and large emission. features. At present, organic waste gas has become one of the four major air pollutants, among which the emission of organic waste gas accounts for a large proportion of the four air pollutants, causing serious pollution to the environment. In addition, organic waste gas contains a large amount of organic matter, directly Emissions also result in a waste of resources. With the gradual improvement of people's living standards ...

Problems solved by technology

The currently developed "adsorption + membrane separation + condensation" process generally adopts activated carbon adsorption and desorption technology, which is an intermittent operation and has high requirements for valves and operations, which leads to many problems such as valve stuck in the actual application process. , which also leads to the inability of the membrane to exert its optimal performance. Therefore, coupling continuous adsorption and desorption processes with membrane separation technology, reducing equipment and operation requirements, and giving full play to membrane performance are of great significance for realizing the recovery and reuse of volatile organic compounds. important meaning
