A kind of poison canister of fire-fighting self-rescue respirator

Abstract

The invention provides a canister for a fire-fighting self-rescue respirator, which includes a shell; a hollow layer is embedded in the inner side of the shell, a fixed block is fixedly connected to the inner wall of the hollow layer, and a heat insulation layer is fixedly connected to one side of the fixed block. The top of the body is provided with an air outlet, and the bottom of the housing is provided with an air inlet. The bottom of the inner wall of the housing is fixedly connected with a poison filter layer, and the surface of the poison filter layer is connected with air holes. When the smoke passes through the deodorizing layer , because the deodorizing layer is corrugated, so when the smoke comes into contact with the deodorizing layer, it first contacts with the trough of the deodorizing layer, and because the trough is convex, the smoke moves to both sides of the trough and moves toward the deodorizing layer. The flue gas moves at the crest of the deodorization layer, and then guides the flue gas through the diversion groove at the bottom of the deodorization layer, so that the flue gas is discharged through the through hole. When the flue gas moves to both sides of the trough, it can not only improve the flue gas and deodorization The contact area of ​​the layers can reduce the odor molecules in the smoke, and facilitate the drainage and discharge of the smoke.

Description

technical field [0001] The invention belongs to the technical field of fire fighting equipment, and more specifically relates to a poison canister of a self-rescue respirator. Background technique [0002] Fire-fighting filter self-rescue respirator is a special respirator that protects human respiratory organs from external toxic gases. filter, which filters out carbon monoxide, hydrogen cyanide, dense smoke, poisonous fog and other toxic gases in the air of the fire scene, making it into harmless air for the escapees to breathe. The core component of the fire-fighting filter self-rescue respirator is the filter However, when the existing canister is in contact with the smoke, it cannot quickly and effectively remove the harmful gas and smoke molecules in the smoke, so that the human body will still inhale the harmful gas and damage the human body, and in the event of a fire, due to The canister is made of metal, and when breathing self-rescue, the canister itself is affec...

Problems solved by technology

[0004] A poison canister for a fire-fighting self-rescue respirator to solve the problem that the existing smoke cannot quickly and effectively remove harmful gases and smoke molecules in the smoke when it is in contact with the smoke, causing the human body to still inhale harmful The gas damages the human body, and in the event of a fire, since the canister is made of metal, the canister itself is affected by the temperature of the fire while breathing and self-rescue, so that the human body inhales high-temperature air, causing discomfort to the human body, which has certain limitations sexual problems
