Description

Technical Field

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

[0002] At present, VOC organic waste gas is often produced in industrial production. VOC organic waste gas refers to volatile organic compounds. According to the definition of the World Health Organization, compounds with a boiling point of 50℃-250℃ under normal conditions are volatile organic compounds; but the definition in the environmental sense refers to a class of active volatile organic compounds, that is, the type of volatile organic compounds that can cause harm. In order to treat this type of waste gas, it is necessary to use a permeable membrane for separation and treatment.

[0003] For example, a membrane separation organic waste gas treatment device disclosed in the authorization announcement number CN213101564U is provided with a support plate and a brush. After the device has been used for a long time, the drive motor can be controlled by the control panel to drive the rotating shaft and the threaded shaft to rotate. The support plate can move up or down on the threaded surface of the threaded shaft, so that the support plate drives the brush to continuously clean the surface of the activated carbon filter plate, the flat membrane assembly, and the high-efficiency particulate filter to avoid blockage, thereby eliminating time-consuming and labor-intensive cleaning steps and reducing the workload of staff during maintenance.

[0004] However, since the cleaning is achieved by moving the brush up and down with a support plate, a larger activity space is required, causing the gas to directly pass through the activity space and cannot be filtered and separated by the permeable membrane. For this reason, we propose a VOC organic waste gas permeable membrane separation device. Utility Model Content
