Air curtain spraying system of novel escape capsule

Abstract

The invention relates to an air curtain spraying system of a novel escape capsule. The air curtain spraying system comprises an air curtain spraying chamber, a compressed air connector is arranged at the inlet side of the air curtain spraying chamber and is connected with a ball valve through a pipeline, the ball valve is connected with the first way of a three-way ball valve through a first pipeline, the second way of the three-way ball valve is connected with an air curtain valve, a mechanical control valve and an air curtain block through a pipeline to form a path, the second way of the three-way ball valve is connected with a spraying valve and a spraying box through a pipeline to form the other path, the third way of the three-way ball valve is connected with a cylinder manifold through a pipeline, the cylinder manifold is connected with pressure reducing valves through pipelines, and the pressure reducing valves are connected with air bottles through pipelines. The air curtain spraying system is compact in structure and reasonable in layout, plays a primary prevention and purification role, and is good in use effect.

Description

technical field [0001] The invention relates to an air curtain spraying system, in particular to an air curtain spraying system in a rescue cabin. Background technique [0002] According to the surveys of mine accidents in various countries in the world, the miners who were injured and died instantly at the scene of fires, explosions and other accidents accounted for only a small part of the total number of accident casualties. High-concentration toxic and harmful gas scene, resulting in suffocation or poisoning death. Therefore, how to provide a confined space for those trapped underground after a mine disaster to avoid the toxic and harmful gas environment and other injuries, and provide them with the necessary survival time until the arrival of rescuers has become a very important topic for mine emergency rescue. [0003] This kind of confined space equipment for protecting trapped miners is called an emergency shelter abroad, and the Chinese security industry calls it a...

AI Technical Summary

Problems solved by technology

[0004] The natural conditions of my country's coal mines are quite different from foreign coal mines and metal mines. They are mainly underground mines, with deep coal seams, narrow mining ground fissures, and high gas content; There are uncertain factors such as gas explosion, water seepage and subsidence, and ordinary foreign emergency shelters cannot meet the needs of domestic mines. At the same time, the cost of foreign related equipment is relatively high, making it difficult to popularize and apply
