Abstract

The invention discloses a high-efficiency purifying material for high-toxicity gaseous pollutants. The material comprises a protective layer I, a function layer and a protective layer II, wherein thefunction layer is arranged between the protective layer I and the protective layer II; the protective layer I and the protective layer II are filter plates formed through compounding 1 to 3 materialsof pretreated dustproof filter cotton, activated carbon fiber, activated carbon filter cotton, glass fiber paper and crocidolite; the function layer comprises 1 to 3 functional filter plates which aremanufactured through a polymerization method and can absorb and remove high-toxicity gaseous pollutants. The material can purify various high-toxicity gaseous pollutants at the same time, can be freely matched with a gas mask according to different types of gases, has the advantages of long use time, good reliability, efficiency and convenience, can recycle absorbed high-toxicity gaseous pollutants through modes, such as temperature rise and pressurization, after the pollutants are absorbed and the material is saturated, and filter plate materials can be reused after recycling.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a high-efficiency purification material for highly toxic pollutants and a device for use. Background technique [0002] A gas mask is a special personal labor protection product, which is worn on the head to protect the human respiratory organs, eyes and face. Its function is to filter toxic gases, radioactive dust, bacteria, viruses, etc. Air. Usually a gas mask is mainly composed of three parts: the canister, the airway and the mask. The mask can be directly connected to the canister, which is called the direct connection type; it is used to connect the canister with the airway, which is called the catheter type. Gas masks can choose various types of canisters according to the protection requirements, and are used in chemical, warehouse, scientific research, and various toxic and harmful working environments. [0003] In 1849, Lewis P. Hasright of the United States ...
