Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a membrane separation treatment VOCS device. Background Art

[0002] VOCS refers to volatile organic compounds, and their main sources are: industrial waste gas generated by fuel combustion and transportation, automobile exhaust, photochemical pollution, combustion products such as coal and natural gas, smoke from smoking, heating and cooking, emissions from construction and decorative materials, furniture, household appliances, automobile interior parts production, cleaning agents and the human body, and volatilization of paints, coatings and adhesives, and solvent-based release agents.

[0003] Membrane gas separation technology is a high-tech technology that is being developed in the world today. It uses the gas pressure difference on both sides of the separation membrane as the driving force. VOCs diffuse through the membrane as a fast gas dissolution, thereby reducing the concentration of the VOCs component on the raw material side of the membrane and enriching it on the permeate side of the membrane, thereby removing VOCs in the air. However, there will still be dust, oil smoke and other components in the treated air. During the long-term use of the separation membrane, oil smoke and dust will accumulate on the separation membrane, thereby reducing the permeability of the separation membrane, so the separation membrane needs to be replaced frequently. However, the current separation membrane replacement process is relatively cumbersome and inefficient. Utility Model Content
