Abstract

The invention relates to a chemical oxygenemergency self-rescue breathing device, which comprises a mask (1), a rebreathing bag (11), an air regeneration tank (5), and an air loop sequentially passing through the mask (1), a one-wayair outlet (4), the air regeneration tank (5), the rebreathing bag (11), one-way air inlets (2,3) and the mask (1). A plurality of supports (7) are arranged in the air regeneration tank (5) and are horizontally fixed on the inner wall of the air regeneration tank (5) to divide the air regeneration tank (5) into a plurality of interconnected subspaces with approximatevolumes; the subspaces are filled with air regenerants (8). The device is provided with a plurality of supports, so that chemical reaction can be quickly conducted to the outer wall of the air regeneration tank in a heating manner so as to improve the heat balance of a circulation air circuit, the reliability of the air regeneration process is controlled, the temperature of fresh air is reduced, and the use comfort of personnel is improved.

Description

Technical field [0001] The invention relates to the technical field of emergency self-rescue devices, in particular to a chemical oxygen emergency self-rescue breathing device. Background technique [0002] The chemical oxygen emergency self-rescue breathing device can chemically react the carbon dioxide and water exhaled by the human body to generate oxygen to form fresh air and be absorbed by the human body. Therefore, in the event of a fire accident, the victims and firefighters trapped in the scene can use chemical oxygen Emergency self-rescue breathing device for on-site evacuation and escape self-rescue. [0003] The chemical oxygen emergency self-rescue breathing device has KO 2 It is the main component of the air regenerating agent. The chemical substances in the air regenerating agent react with the carbon dioxide and water exhaled by the human body to produce fresh air for breathing. It is not restricted by the gas composition of the surrounding atmosphere when used. The...
