Problems solved by technology

[0004] However, today's compressed air supply system has a complex structure and is inconvenient to install and operate. Due to the large number of compressed air bottles required, the entire compressed air supply device occupies a high rate of refuge chamber space, and most systems use low-pressure confluence air supply way, making the cost higher, and most of the gas supply pipelines in the system are stainless steel pipes, which makes the pressure loss rate of the gas larger

Abstract

The invention belongs to the technical field of compressed air supply systems; the technical problem to be solved is that a compressed air supply system with a simple structure and convenient operation is provided. According to the technical scheme, the compressed air supply system comprises a compressed air supply device, an air curtain spraying system and an ice storage air conditioning system, wherein the compressed air supply device is used for supplying air for the ice storage air conditioning system through a first pipeline and supplying air for the air curtain spraying system through a second pipeline; the compressed air supply device comprises a confluence pipeline and at least one bypass pipeline, an air outlet of each bypass pipeline is communicated with the confluence pipeline, an air inlet of each bypass pipeline is connected with a compressed air bottle, a control valve is arranged on each bypass pipeline, and the two ends of the confluence pipeline are respectively communicated with the first pipeline and the second pipeline. The compressed air supply system is suitable for the field of coal mines.

Description

technical field [0001] The invention belongs to the technical field of compressed air supply system. Background technique [0002] As an important part of the underground emergency avoidance system, the refuge chamber can withstand the impact of gas explosions and isolate toxic gases. Especially when a mining disaster occurs underground, the refuge chamber can provide safe and airtight survival for those who cannot evacuate in time Space, and provide oxygen, food and water and other survival necessities for the escape personnel, so as to buy precious rescue time for people. [0003] The compressed air supply system is an important part of the refuge chamber. It can provide air source for the air curtain sprinkler system and the passive ice storage air conditioning system when the mine compressed air system is damaged, so as to ensure the orderly operation of each functional module in the refuge chamber. Normal work, so as to provide a more comfortable living environment for...
