Drying and purification of general-purpose compressed air and sterile compressed air in breweries
The general power air and sterile compressed air drying and purification requirements for breweries are as follows: 1. Dew point -23℃; 2. Dust particle size less than 0.1μm; 3. Oil-free; 4. Sterile. According to the above requirements 1-4, the general power air of the brewery only needs to be equipped with a refrigeration dryer and a primary filter to meet the requirements. However, the requirement for sterility greatly increases the workload and difficulty of purification.

Examples of automotive manufacturing plant electrostatic spraying and painting lines
The quality of car paint repair, in terms of both color and durability, is inferior to the original. More seriously, after a period of use, the repaired paint will wrinkle and become orange peel-like. The main reason is that the oil and water in the compressed air are not effectively removed, affecting the adhesion and gloss of the paint. When the car is parked outdoors and under direct sunlight, the oil and paint will slowly undergo a chemical reaction under high temperatures, causing the paint surface to shrink and wrinkle. Currently, many factories have made a commitment to paint that remains unchanged for ten years. The question of how to achieve this commitment becomes a question of how to ensure that the compressed air purification level meets the requirements.

Problems caused by compressed air contamination
All compressed air in compressed air systems comes from the atmosphere, which contains a large amount of dust, water vapor, incompletely combusted hydrocarbons, and bacteria. In addition, the lubrication system of the air compressor will also produce pollutants such as wear particles and oil. This oil is acidic and is a poor quality oil that does not provide any lubrication. Corrosion of the pipelines in the compressed air distribution system will also pollute the compressed air.

Application examples of compressed air in LCD production
Mobile phone displays, various touch screens, and LCD TVs all use LCD displays. Their production process also requires a large amount of clean compressed air. Compared to general compressed air applications, the requirements for compressed gas are: 1. Low pressure dew point (-70~-100℃); 2. Small dew point fluctuation (2%-3%); 3. The system cannot contain copper.

Layout of compressed air station
The placement of compressed air stations within plants (mines) should be determined based on the following factors after technical and economic comparisons: 1. Proximity to the air consumption load center; 2. Reasonable power and water supply; 3. Possibility of expansion; 4. Avoid proximity to places emitting explosive, corrosive, and toxic gases, as well as harmful substances such as dust, and be located on the leeward side of such places with the lowest annual wind frequency; 5. The distance between the compressed air station and places with noise and vibration protection requirements should comply with the provisions of current national standards and regulations.

Heating and ventilation of compressed air station
The heating temperature in the compressed air station machinery room should not be lower than 15℃, and the temperature in the machinery room during non-working hours should not be lower than 5℃. The summer air temperature within 2m above the ground of the entire machinery room should comply with the requirements for workplaces in workshops in the current national standard GBZ1 "Industrial Enterprise Design Hygiene Standard".
