Abstract

The invention relates to breathing equipment for mine rescue, in particular to a carbon dioxide absorbing device for an isolation-type positive-pressure oxygen respirator. The carbon dioxide absorbing device comprises a box body provided with a cover and used for accommodating a carbon dioxide absorbent; an air inlet and an air outlet which are provided with threads are formed at opposite positions on the side wall of the box body; the cover is arranged on the upper part of the box body and is in sealed fit with the side wall of the box body; and the carbon dioxide absorbent is arranged in the box body. By the technical scheme, in the carbon dioxide absorbing device for the isolation-type positive-pressure oxygen respirator, the carbon dioxide absorbent is easy and convenient to change, and installation errors hardly occur.

Description

technical field [0001] The invention relates to a breathing device for mine rescue, in particular to a carbon dioxide absorbing device of an isolated positive pressure oxygen respirator. Background technique [0002] The isolated positive pressure oxygen respirator is a device used by mine rescuers or fire fighters in rescue and relief work in suffocating or toxic and harmful gas environments. It can also be used in national defense, nuclear industry, aerospace, petrochemical, metallurgy, urban construction, It is used by specially trained personnel in industries such as tunnels to prevent or deal with accidents in life-threatening and health-threatening environments. Its working principle is: the human respiratory system and the respirator form a positive pressure human-machine respiratory system isolated from the outside world. The gas then passes through the exhalation hose, flows through the carbon dioxide absorber equipped with carbon dioxide absorber, and then re-ente...
