Description

[0001] Technical field: [0002] The invention mainly relates to the technical field of waste gas from a tempered, tempered and viscosity-adjusted steam jet pump, and in particular to a treatment device and a treatment method for waste gas from a tempered, viscosity-adjusted steam jet pump. [0003] Background technique: [0004] In the chemical fiber production industry, for example, the tempering and viscosity-adjusting technology of waste plastic raw materials used in polyester staple fiber production is mainly: sending the melted liquid waste plastic raw materials into its special vacuum separation tower, which has multiple layers of porous Plate, the liquid raw material passes through the porous plate layer by layer to increase the surface area, gasify and separate low-molecular impurities, improve the purity and viscosity of the raw material, and greatly improve the quality of the finished product. A vacuum generator is needed in the tempering and viscosity adjustment pro...

AI Technical Summary

Problems solved by technology

A vacuum generator is needed in the tempering and viscosity adjustment process, which is connected to the liquid waste plastic raw material container through the suction pipe. At present, steam jet pumps that are relatively insensitive to dust are mostly used to provide a reaction environment for the increase of raw material viscosity. ; During the working process of the jet pump, due to the volatilization and heat dissipation of the raw materials, a large amount of waste gas will be produced. The temperature of the waste gas can generally reach 80-90 ° C, and the water content of the waste gas is as high as 70-80%. VOC (volatile organic compound , refers to a class of active volatile organic compounds, that is, the class of volatile organic compounds that will cause harm) with a content of up to 1000mg / m 3 , with obvious foul smell, if it is directly discharged into the environment without treatment, it will cause serious pollution to the environment
