High-temperature-resisting compressed oxygen self-rescuer for fire prevention and protection and rescue

Abstract

The invention relates to a high-temperature-resisting compressed oxygen self-rescuer for fire prevention and protection and rescue. A protective jacket is arranged outside the self-rescuer and consists of an aluminum foil radiation-resisting and temperature-resisting layer, a flame-retardant and heat-insulating layer and an inner protecting layer which are arranged from outside to inside; a compressed oxygen bottle, a rebreathing bag, a CO2 absorbent and a proportioning valve are arranged inside the projective jacket; a breathing mask connected with the proportioning valve is arranged outside the protective jacket; the compressed oxygen bottle is tapped with a pressure gauge, a silencer II and an opening valve through a silencer I; the opening valve is connected with the proportioning valve through a silencer III; the proportioning valve is connected with the rebreathing bag; the rebreathing bag is connected with a breathing valve and the CO2 absorbent through a pipeline Y. According to the high-temperature-resisting compressed oxygen self-rescuer disclosed by the invention, fire resistance, fire prevention, radiation resistance and heat insulation can be effectively realized; the high-temperature-resisting compressed oxygen self-rescuer is necessary for users to breath in toxic or harmful environment, a dense smoke environment and an extreme oxygen-deprivation environment of a fire scene, and provides a chance for the users to quickly escape from disaster scenes and be rescued.

Description

technical field [0001] The patent of the invention relates to the field of emergency equipment, in particular to a compressed oxygen self-rescuer for high temperature resistance, fire prevention and fire rescue. Background technique [0002] my country has a vast territory, a large population, and many high-rise buildings. Various production enterprises with potential fire hazards are spread all over the country. Fires occur frequently every year. Every autumn and winter, large and small forest fires also emerge in endlessly. Due to the complexity of various fire scenes, the fire is difficult It is expected that there will even be explosive deflagration, which will bring great danger to the firefighters involved in the rescue work, and cause firefighters to be injured or even disabled. These are all caused by inhalation of toxic smoke and carbon monoxide gas after the fire and explosion. [0003] At present, the fire departments of some large cities are equipped with a small ...
