Positive-pressure fire-fighting air breathing apparatus

Abstract

The invention discloses a positive-pressure fire-fighting air breathing apparatus. The air breathing apparatus comprises a flame-retardant garment, air bottles and a mask; gas cylinder fixing frameworks are arranged on the front side and the rear side of the flame-retardant garment; filler is arranged in the flame-retardant garment, a detachable heating and refrigerating inner container is arranged on the inner side of the flame-retardant garment, and a high-brightness guide lamp is arranged at the chest position; the air bottles are quick-change carbon fiber composite bottles and are fixed tothe flame-retardant garment in a sticking manner; and an air supply valve is arranged on the mask, a pipeline is arranged between the air bottles, a control panel is arranged at one end of the pipeline, and a pressure alarm device is arranged in the pipeline. The air breathing apparatus has the beneficial effects that the flame-retardant garment which is filled with high-strength fibers and the composite-material smash-proof and stab-proof filler and is provided with the detachable heating and refrigerating inner container is adopted, so that the danger to the safety of rescuers and rescued persons due to sudden falling of sundries in the rescue process and over-high or over-low temperature is effectively avoided; and the firefighter safety is guaranteed through the light design and intelligent utilization, practicability and convenience are achieved, operation is easy, and large-area application and popularization can be achieved.

Description

technical field [0001] The invention relates to the technical field of safety protection, in particular to a positive pressure fire-fighting air respirator. Background technique [0002] The air respirator is a kind of self-protection device used by firefighters. It uses the mask and the air supply valve on the mask to seal with the periphery of the wearer's face, so that the respiratory organs, eyes and face are completely isolated from the external poisonous air or hypoxic environment. Isolation, with its own compressed air source for the wearer to use clean air through the air supply valve. The pressure inside the mask is greater than the ambient pressure. The pressure of the self-contained air source is tracked by the pressure gauge as the working time increases. The temperature during the actual rescue process is too high or If it is too low, the firefighters will be abnormal, and during the rescue process, the sudden falling debris, hot fire radiation, and the previous...
