Working principle: When using the self-cleaning adsorption fiber filter structure for gas treatment, as shown in Figure 1-2, the left and right ends of the filter box 1 can be normally connected to the gas treatment ventilation pipeline, and placed in a suitable working place. Under the action of the external fan, the body passes through the coarse filter screen plate 2, the secondary filter plate 3, the activated carbon adsorption layer 4, the nanofiber filter membrane 5 and the wet curtain 6 for multiple filtration and impurity removal. It can be combined with spraying to improve the gas humidity to a certain extent while processing the gas.

After the device is used for filtration for a period of time, as shown in Figures 1-3, impurities are likely to accumulate outside the multi-layer filter structure, especially the coarse filter screen plate 2 affected by the outermost layer and the nanofiber filter membrane 5 that is easily affected. At this time, the driving process can be performed by starting the driving motor 25, or the external control circuit can set the driving motor 25 to perform the timing start processing.
