Description

Technical Field

[0001] The utility model belongs to the technical field of safe storage of hazardous wastes, and in particular relates to a mobile safe storage device for hazardous wastes. Background Art

[0002] Hazardous waste refers to waste that is listed in the "National Hazardous Waste List" or is identified as having hazardous characteristics according to the national hazardous waste identification standards and identification methods. Hazardous waste has various toxic, corrosive, flammable, explosive, reactive and infectious properties, which will cause serious harm to the ecological environment and human health. Hazardous waste safety storage equipment is a place for receiving and temporarily storing hazardous waste to be processed. The temporarily stored hazardous waste is of many types, with complex chemical composition, and contains a large number of flammable, explosive, toxic and harmful substances.

[0003] At present, most of the existing safe storage equipment for hazardous waste utilizes closed spaces to store hazardous waste. Since they do not have the function of exhaust gas treatment, the harmful gases emitted by hazardous waste accumulate in the space, which is dangerous and may cause gas leakage or explosion risk due to excessive air pressure. Moreover, most hazardous waste storage equipment directly places hazardous waste in it. Since they do not have a barrier function, during multiple storage processes, the inside of the equipment will be in direct contact with the outside world, which may also cause gas leakage. For this reason, we propose a mobile safe storage equipment for hazardous waste. Utility Model Content
