Stable gas supply system

Abstract

The invention relates to the field of special operation air supplying, in particular to a stable air supplying system. The stable air supplying system comprises an air inlet pipe, a respiration separator, at least one air outlet pipe and protective suits, and the air inlet pipe, the respiration separator, the air outlet pipes and the protective suits are connected in sequence. The respiration separator comprises a shell, an air inlet, at least one air outlet, an air filtering device and a gas flow distribution device, and the air filtering device and the gas flow distribution device are arranged in the shell. The air inlet is connected with the air filtering device through an air inlet header pipe. The air filtering device is connected with the gas flow distribution device. The gas flow distribution device is connected with the air outlets. The gas flow distribution device comprises an air outlet header pipe, a distributor connected to the air outlet header pipe, at least one air outlet branch pipe connected to the distributor and flow control valves arranged on the air outlet branch pipes. The air outlet header pipe is connected to the output end of the air filtering device. The air outlet branch pipes are connected to the air outlets. The stable air supplying system is convenient to use and capable of providing continuous and stable gas flow, preventing outside toxic and harmful gases from entering the protective suits and being inhaled by operators, and effectively reducing potential safety hazards.

Description

technical field [0001] The invention relates to the field of gas supply for special operations, in particular to a stable gas supply system. Background technique [0002] With the continuous development and progress of science and technology, the environment that people face is becoming more and more complex, and various sudden accidents occur frequently, such as fires, explosions of combustible materials, collapse of buildings, etc. These special environments have high temperature and high radiation. , high concentration of toxic and harmful substances, how to ensure the normal breathing of the workers when carrying out rescue, provide them with a clean air supply with stable pressure, and prevent the toxic and harmful gases in the environment from being inhaled, etc., are placed in front of the rescue team a difficult problem. [0003] In the prior art, when workers work in these special environments, they usually wear protective clothing, and then carry the gas storage t...

Problems solved by technology

However, this method has the following disadvantages. First, the operator shoulders the gas storage tank, which is heavy and inconvenient to move, which is not conducive to the smooth development of rescue work. Second, the gas storage capacity of the gas storage tank is limited. At this time, the operator needs to suspend the operation and return to a safe place to replace the new gas storage tank, and then return to the site to continue working, which is inconvenient to use and low in work efficiency. supply, cannot form a stable negative pressure system in the protective clothing, the toxic and harmful gases from the outside will enter the protective clothing due to the low pressure in the protective clothing, and be inhaled by the workers, affecting the health of the workers and posing safety hazards
