Problems solved by technology

The VOC in the industrial production process is generally a single volatile organic compound. If it is discharged over a long period of time, it will cause serious air pollution and cause a lot of waste.
At present, the treatment of VOC is generally by solvent absorption, but it has the disadvantages that the absorption solvent cannot be reused, produces secondary pollutants, the device cannot be operated continuously, and the cost of environmental protection treatment is high.

Abstract

The invention relates to a device used for absorbing VOC with a high boiling point solvent and recycling. The device comprises a cooling blending tank, a cooler I, a cooler II, and a venturi mixer which are connected through pipelines; the top end of the cooling blending tank is provided with a wire mesh demister; the external part of a tank body of the cooling blending tank is provided with a refrigerant jacket; the lower part of the refrigerant jacket is provided with a refrigerant inlet, and the upper part is provided with a refrigerant outlet; the refrigerant inlet is provided with a compressed gas source inlet; and the refrigerant outlet is provided with a steam inlet. The high boiling point solvent used for absorbing can be recycled; entire continuous operation is realized; operationis smooth and reliable; and cost is reduced.

Description

technical field [0001] The invention relates to a waste gas recycling device, in particular to a VOC recycling device. Background technique [0002] As a volatile organic compound, VOC easily forms PM2.5 aerosols with water vapor and microparticles in the air after volatilization into the atmosphere, forming smog, causing great damage to the atmospheric environment and affecting human health. VOC in the industrial production process is generally a single volatile organic compound. If it is discharged over a long period of time, it will cause serious air pollution and cause a lot of waste. At present, the treatment of VOC is generally by solvent absorption, but it has the disadvantages that the absorption solvent cannot be reused, produces secondary pollutants, the device cannot be operated continuously, and the cost of environmental protection treatment is high. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to overcom...
