Air compression post-processing is a key process to ensure the quality and purity of compressed air. it is mainly through a series of equipment for air compression cooling, remove water, filter, dry and other treatments. The following are the main equipment and functions of air compression post-processing, as well as the importance of air compression post-processing:
I. Main equipment and functions of air compression post-processing.
- Air tank: The air tank plays the role of buffering, cooling, dehydration and oil removal in the air compression system. It can absorb the fluctuation of compressor exhaust volume and stabilize the output pressure, while condensing and setting the water vapor in the compressed air and discharging it through the drain valve. In addition, the air tank can further separate and precipitate impurities in the compressed air to improve air quality.
- Filter: The filter is the main equipment for removing solid particles and liquid water in compressed air. It usually consists of a filter element can be selected with different filtering precision as needed. The filter can remove impurities such as dust, oil mist and microorganisms in the compressed air to ensure the cleanliness of the compressed air.
- Dryer: Dryers are used to remove moisture from compressed air to prevent moisture from causing corrosion and contamination in pipes and equipment. Common types of dryers include refrigerated dryers and adsorption dryers. Refrigerated dryers condense moisture and discharge it by lowering the temperature of compressed air. On the other hand, adsorption dryers use adsorbent (such as molecular sieves) to adsorb water in compressed air.
- Oil-water separator: Oil-water separators are mainly used to remove oil in compressed air. It separates the oil from the air by physical or chemical methods to ensure the purity of air compression. Oil-water separators are particularly important in industries such as food processing and pharmaceuticals that have high requirements for air quality.
- Cooler: Coolers are used to reduce the temperature of compressed air to improve the effect of subsequent processing equipment and extend the life of the equipment. When the exhaust temperature of the compressor is very high, the compressed air will contain a large amount of moisture and oil, which exceeds the operating conditions of the subsequent purification equipment. Therefore, it is necessary to use a cooler to cool down and remove water.
II. Importance of air compression post-processing.
- Improve product quality: The post-processed compressed air has reached a very low level in terms of residual oil content, dust particle size and dust concentration, which can avoid pollution to the product and improve product quality.
- Extend equipment life: Impurities and contaminants can cause corrosion and wear to pipes, valves and equipment in the air compression system, shortening the life of the equipment. These impurities and pollutants can be effectively removed through post-processing to protect system equipment.
- Reduce maintenance costs: Since post-processing equipment can reduce the accumulation of impurities and pollutants in the system, the maintenance cost of the system can be reduced. At the same time, high quality air compression can also improve the working efficiency and stability of the system.
- Ensure production safety: In some industries with extremely high requirements for air quality (such as food processing, pharmaceuticals, etc.), untreated compressed air may introduce harmful substances or microorganisms to contaminate produces, posing a threat to consumer health. Therefore, air compression post-processing is crucial to ensuring production safety and product quality.
In summary, air compression post-processing is a necessary process to ensure the quality and purity of air compression, it uses a series of equipment to compress air for cooling, water removal, filtration, drying and other processing to improve product quality, extend equipment life, reduce maintenance costs and ensure production safety.
