Multifunctional filter tank for gas mask

Abstract

The invention belongs to the technical field of personal filter protecting apparatuses, in particular to a multifunctional filter tank for a gas mask. The multifunctional filter tank comprises a top cover, a tank body and a sealing cover. The top cover and the upper edge of the tank body are compacted and sealed and glued integrally, a notch is formed in the bottom of the tank body, the sealing cover is embedded into the notch, air outlet sieve pores are formed in the bottom of the tank body, and a mounting thread is processed on the outer wall of the bottom of the tank body, so that the multifunctional filter tank for the gas mask is connected to the gas mask; air inlet sieve pores are formed in the top cover; and a smoke filter layer, a radioactive adsorption layer, an activated carbon layer, a biomass adsorption layer, a macromolecular adsorption layer and a smoke filter layer are arranged in the tank body from top to bottom. Filling materials in the radioactive adsorption layer, the biomass adsorption layer and the macromolecular adsorption layer in the multifunctional filter tank for the gas mask are rare earth-based metal oxide-loading materials. The materials are good in stability and high in selectivity and can be used for absorption, catalytic oxidization or deactivation and the like of special substances.

Description

technical field [0001] The invention belongs to the technical field of personal filter protective equipment, in particular to a multifunctional filter tank for a gas mask. Background technique [0002] Gas masks, a kind of protective equipment to protect the respiratory tract, are widely used in petroleum, chemical, mining, metallurgy, military, firefighting, emergency rescue, health and epidemic prevention, technology and environmental protection, machinery manufacturing and other fields, mainly to protect the personal respiratory system. Gas masks are mainly divided into two parts, one is the mask, and the other is the filter tank. In terms of function, the main function of the gas mask is the "filter tank". Filter tanks with different fillings have targeted protection for different environments. . [0003] For general commercial gas masks, the filter tank is mainly filled with activated carbon materials, and the filtering of harmful substances mainly depends on the physi...

AI Technical Summary

Problems solved by technology

Therefore, the protection efficiency for relatively small toxic molecules is not high, and the protection time is very short.

At the same time, there are various types of external dangers, such as chemical pollution, smog, biological threats, and the recent new crown virus, etc. General gas masks have a single protective performance and only target one type of pollutants

For complex pollution environments, the protection efficiency is greatly reduced
