Problems solved by technology

For example, in the papermaking industry, there will be a lot of dust in the working environment, as well as fiber rot and various polluting gases produced by the papermaking process. However, the gas masks used only have the function of filtering, and do not have the function of filtering and eliminating harmful gases. , will damage the health of workers

Embodiment 1

[0022] A poison canister with a purification function, which comprises a first adsorption part, a catalytic part and a second adsorption part stacked one after the other.

[0023] The first adsorption component is provided with a fiber filter layer, and the fiber filter layer is sequentially superimposed with a paper fiber filter layer and an ultrafine glass fiber filter layer.

[0024] The catalytic component is provided with a catalyst layer, and the catalyst is prepared by an impregnation method, including the following components,

[0025] A) 10% Al 2 o 3 The supported Ce / Zr composite oxide has a molar ratio of each component Ti:Ce:Zr of 1:0.08:0.08;

[0026] B) 5% of V 2 o 5 / (MoO 3 ) 0.4 (WO 3 ) 0.6 / TiO 2 Composite oxide, wherein the molar ratio of V:Mo:W:Ti is 2:0.4:0.6:1;

[0027] C) the ZSM-5 molecular sieve of balance.

[0028] The second adsorption layer is composed of activated carbon and silver-loaded nano-titanium dioxide with a mixing mass ratio of 3...

Abstract

The invention relates to a canister for a gas mask, and discloses a canister with a purification function. The canister comprises a first adsorption part, a catalysis part and a second adsorption part, wherein the first adsorption part, the catalysis part and the second adsorption part are stacked front and back. By means of a catalyst, after removing is carried out, the concentrations of benzene, methylbenzene, dimethylbenzene, ethylbenzene, styrene, formaldehyde, acetaldehyde and acrolein in the air in a building can be smaller than 0.01 milligram per cubic meter, and meanwhile the content of microorganisms in circulating air is remarkably reduced.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a canister for a gas mask. Background technique [0002] As personal protective equipment, gas masks are used to provide effective protection for personnel's respiratory organs, eyes and facial skin. The mask is composed of a mask, an airway and a canister. The mask can be directly connected to the canister or the canister, which is called a direct connection; or the airway is connected to the canister and the canister, which is called a catheter. Mode. 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] A common gas mask consists of a face shield and a canister (or filter element). The mask includes parts such as a cover body, an eye window, a communicator, a breathing valve, and a headband (or helmet). The cani...
