Pipe network system and method for increasing oxygen yield by using surplus compressed air

Abstract

The invention discloses a pipe network system for increasing oxygen yield by using surplus compressed air, and relates to the technical field of oxygen generators. The pipe network system comprises a compressed air supply end, a constant-pressure conveying pipeline, an air cooling device, an air molecular sieve removal purification system and an oxygen generation device, wherein the inlet end of the constant-pressure conveying pipeline is connected with the compressed air supply end, the constant-pressure conveying pipeline comprises a conveying pipeline, and a first stop valve, a flow meter, a check valve, a pressure transmitter, an adjusting valve and a second stop valve are sequentially arranged on the conveying pipeline from the inlet end to the outlet end of the conveying pipeline; the inlet end of the air cooling device is communicated with the outlet end of the constant-pressure conveying pipeline; the inlet end of the air molecular sieve removal purification system is communicated with the outlet end of the air cooling device; and the inlet end of the oxygen generation device is communicated with the outlet end of the air molecular sieve removal purification system. According to the pipe network system and method, surplus compressed air resources of an air compression station are integrated, and the defects of an air compressor of the oxygen generator are overcome, so that the diffusion rate of compressed air of the air compression station can be reduced, the oxygen yield can be increased, and the supply cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of oxygen generators, in particular to a pipe network system and method for increasing oxygen production by using surplus compressed air. Background technique [0002] In summer, it is hot and rainy, and the air contains a lot of humidity. The air capacity of the air compressor system designed for the oxygen generator in the oxygen plant is seriously insufficient, resulting in a serious drop in the oxygen output of the oxygen generator, and there is a gap in the supply of oxygen. The oxygen plant has to High-priced purchased liquid oxygen is oxidized to meet the oxygen demand, which greatly increases the cost of supply guarantee. At the same time, the air compressor station daily guarantees the supply of equipment, and the average release rate of compressed air in the company is about 2%. In order to control the release loss, some equipment operates with reduced load and low efficiency, resulting in a lot of...

[0002] In summer, it is hot and rainy, and the air contains a lot of humidity. The air capacity of the air compressor system designed for the oxygen generator in the oxygen plant is seriously insufficient, resulting in a serious drop in the oxygen output of the oxygen generator, and there is a gap in the supply of oxygen. The oxygen plant has to Purchasing high-priced liquid oxygen to oxidize to meet oxygen demand, which greatly increases the cost of supply guarantee

At the same time, the air compressor station maintains the daily supply of equipment, and the average release rate of compressed air in the company is about 2%. In order to control the release loss, some equipment operates with reduced load and low efficiency, resulting in a lot of energy waste
