Description
Technical Field
The invention relates to the technical field of respirators for fire protection, in particular to a novel self-oxygen-generating fire-fighting respirator.
Background
Currently, two types of firefighter respirators widely used by national firefighting rescue teams are mainly a positive pressure type firefighting air respirator and a positive pressure type firefighting oxygen respirator.
The positive pressure fire-fighting air respirator is a self-contained open air respirator, and is widely applied to departments such as fire protection, chemical industry, ships, petroleum, smelting, warehouses, laboratories, mines and the like for firefighters or rescue workers to safely and effectively extinguish fire, rescue and rescue under various environments such as dense smoke, toxic gas, steam or oxygen deficiency and the like. The mask is tightly sealed with the periphery of the face of the wearer, so that the respiratory organs, eyes and the face of the wearer are completely isolated from outside polluted air or anoxic environment, clean air used for breathing of the wearer is supplied from a compressed air source, the expired air is directly discharged into the atmosphere, and the pressure in the mask is higher than the ambient pressure in any respiratory cycle process.
The positive pressure type oxygen respirator for fire fighters and rescue workers is used for rescuing and disaster relief or working in disaster treatment in severe environments such as poisonous, anoxic, smog, harmful pollutants suspended in air and the like. The high-pressure oxygen bottle is filled with compressed oxygen as an air source, the oxygen in the oxygen bottle is used during breathing, the breathing cabin (or the air bag) is used as an air storage device, and the air pressure in the mask is greater than the respirator of the external atmospheric pressure.
Both respirators have great limitations in normal use by firefighters. The air respirator is limited by the capacity and the pressure of the steel bottle, the common protection time is not more than 45 minutes, and under the conditions of work tension and high-strength working conditions such as fire-extinguishing rescue, the common protection time is less than half an hour, so that the problem that the actual fire-extinguishing rescue combat needs cannot be met in time is more and more prominent; the oxygen respirator adopts the oxygen steel bottle, so that the oxygen respirator is not recommended to be used in fire fighter fire rescue, and the problem of serious limitation in the use field is more remarkable.
Therefore, we propose a novel self-generating oxygen fire-fighting breathing machine.
