Method for improving compressed air quality of air compression station

Abstract

The invention provides a method for improving the quality of compressed air of an air compression station, which comprises the following steps of: filtering air by an air filter, removing dust and mechanical impurities in the air, compressing the air by an air compressor, and pre-washing and cooling the air in an air cooling tower in an air pre-cooling system; then the air is adsorbed and purified by a molecular sieve in the molecular sieve adsorber, and then enters a buffer tank for pressure stabilization and storage; the air pre-cooling system is used for washing and cooling, a molecular sieve adsorber in the purification system is used for adsorbing and removing moisture, carbon dioxide and hydrocarbon in air, the quality of a compressed air product reaches the first-grade standard, the air cooling tower is used for replacing an original freezing dryer, and the energy consumption is reduced. The molecular sieve and the activated aluminum oxide are activated and regenerated by using the waste nitrogen produced by the oxygen production system, so that the energy consumption is obviously reduced, the production cost is reduced, the production efficiency and the economic benefit are improved, and the environmental protection is facilitated.

Description

technical field [0001] The invention relates to the technical field of air compressor station equipment, in particular to a method for improving the compressed air quality of an air compressor station. Background technique [0002] The air compressor station is a compressed air station. The compressed air generated by the air compressor is stored in the air storage tank. It must undergo a series of treatments such as cooling, purification, decompression, and pressure stabilization before it can be supplied to the control components (various valves, logic, etc.) Components, etc.) and actuators (cylinders, motors, etc.). The air compressor station usually includes an air compressor, an air storage tank, a dryer (including two types of freeze dryer and adsorption dryer) and a filter for dust and oil removal. [0003] In the prior art, alumina is used to absorb moisture in the air compressor station, and the finished compressed air is used to activate the regeneration process, ...

AI Technical Summary

Problems solved by technology

The air compressor station in the prior art has the following problems and defects: the production process consumes a lot of energy; post-processing uses self-produced finished product compressed air to activate regenerated alumina, resulting in increased energy consumption; the service life of alumina is short, generally within 2 It needs to be replaced every year; the quality of compressed air can only be controlled to Grade 3 standard, resulting in high dew point of compressed air and low air cleanliness, resulting in high failure rate of equipment for various users in the steel plant and increasing control costs

[0004] In the prior art, the energy consumption of the air compressor station is high, and the raw material of the air compressor station is air, which mainly consumes energy, which accounts for the vast majority of production costs
