[0002] Benzene is highly toxic and is also a carcinogen. When workers are working in an open-air toxic environment containing benzene, they need to take personal protection measures to prevent poisoning and occupational diseases. At present, during the loading and unloading of toxic materials containing benzene, although the oil and gas recovery device is enabled, there are still some toxic gases in the operating range, and workers need to wear gas masks to work. The gas masks currently used are mostly 3M3200 half masks. This type of gas mask uses a 3301CN filter box and 3N11CN filter cotton. The filter box has a short service life and needs to be frequently replaced during the operation. Not only is the cost of use high, but it also prolongs the loading and unloading time. It may also cause poisoning and occupational diseases due to untimely replacement of the filter box. Therefore, it is necessary to take measures to reduce or avoid the frequency of replacing the filter box, reduce costs, and improve work efficiency. Utility Model Content
