Product Description

ZH30 mining Isolated chemical oxygen self-rescuer

Product Description

The self-rescuer is an isolated regenerative self-rescuer with chemical oxygen as the gas source. The human respiratory system is isolated from the outside world, which can prevent various toxic and harmful gases from entering, and can be used when people in distress escape.
The self-rescuer has the advantages of small size, light weight, simple operation, reliable performance, and convenient carrying.
This self-rescuer is mainly used in coal mines or in various toxic gas and oxygen-deficient environments, coal dust and gas outbursts, explosions in mines and places with CO2 outbursts, for individuals to wear for self-rescue, and protect people from breathing normally to escape the disaster area.
This self-rescuer can also be used in modern high-rise buildings and in toxic and harmful gas or oxygen-deficient environments. When a catastrophic fire occurs, it can be worn by the victims to escape and use when waiting for rescue.

Product Parameters

The breathing gas path of the self-rescuer is reciprocating advanced exhaust, the self-rescuer is isolated from the outside world, and its use is not restricted by the harmful gases in the surrounding environment. It uses potassium superoxide flake rapid oxygen generating agent (oxygen generating agent should meet the MT427-1995 standard requirements ), when the wearer exhales, the exhaled water vapor and CO 2 react with the oxygen generating agent in the medicine tank through the oral appliance, cooling net, central tube, lower plate, etc.:


2KO₂+H₂O   →   2KOH+1.5O₂+Calories↑


2KOH+CO₂      →    K₂CO₃+H₂O+Calories↑
The water vapor reacts with CO2 and the oxygen generating agent to remove most of the carbon dioxide to generate oxygen with higher oxygen content, which enters the airbag through the upper plate group. When inhaling, the oxygen stored in the air bag passes through the upper plate group, the oxygen generating agent, In the lower plate group, the central tube and mouthpiece enter the human lungs to complete the entire breathing cycle.
When the oxygen generated by the oxygen generating agent exceeds the oxygen consumed by the human body, the more oxygen enters the airbag, and the pressure in the airbag gradually increases. When the exhaust pressure is reached, the exhaust valve on the airbag opens automatically, and the person exhales the gas It is directly discharged from the central hose of the airbag to avoid waste of oxygen. When the pressure in the airbag decreases, the exhaust valve is automatically closed to resume reciprocating breathing.
