ZH Series Isolated Chemical Oxygen Self Rescuer

Introduction of ZH Series Isolated Chemical Oxygen Self Rescuer

ZH Series Isolated Chemical Oxygen Self Rescuer is an isolated closed circuit breathing apparatus. 
Mainly used in coal mines or ambient air pollution and toxic gases occurring hypoxic choking hazard, the site quickly worn to protect people fleeing the disaster area normal breathing.
chemical oxygen self-rescuer respiratory protection for the respiratory gas reciprocating, 
using KO2 flaky oxygen oxygen enerating agent, candles starter. Breath by mouth with oxygen bottles of medicine into the raw produce oxygen absorb carbon dioxide, oxygen-containing gas into the airbag. Inhale, airbag gas purification by re-entering the mouth with bottles of medicine, oral inhalation, 
because oxygen generating agent in oxygen uptake than raw speed of the body consumes oxygen, respiratory protection when the gas is greater than the exhaust valve opening pressure, exhaust automatically open the exhaust valve, lower than the exhaust pressure, exhaust valve automatically shut down to protect the respiratory isolation with the outside atmosphere. 
Oxygen generating process main reaction equation is: 
          2KO2+H2O→2KOH+1.5 O2+heat
          2KOH+CO2→K2CO3+H2O+heat
