The role of air compressor cold dryer
The cold dryer is the core post-processing equipment used to remove moisture in the compressed air in the air compressor system. Its core function and value to the entire air compressor system can be divided into the following parts:
core function: remove excess moisture in compressed air
after the air is compressed by the air compressor, the gaseous water vapor originally contained will become supersaturated due to changes in temperature and pressure, and it is easy to condense into liquid water. The cold dryer relies on refrigeration technology to cool the high-temperature compressed air, so that the original gaseous water vapor becomes liquid water droplets, and then the liquid water is collected by the separation device and discharged from the system, and finally the dry compressed air is output.
Compared with the adsorption drying method, the operating cost of the cold dryer is lower, which can fully meet the drying needs of most conventional production scenarios.
Protective effect on air compressor system and production
protection of piping and terminal equipment
if the moisture in the compressed air is not treated, it will slowly corrode the air conveying pipes, and will also make the terminal air equipment such as pneumatic valves and pneumatic motors rust and jam, aging and damage in advance, thus increasing the maintenance cost of the equipment.
Ensure the quality of end products
compressed air with moisture if direct contact with the production of products, will affect the production process, such as spraying will appear bubble paint, food and pharmaceutical production will be affected with moisture deterioration, to the production of irreparable losses, cold dryer after drying can avoid such problems.
Ensure stable operation of production
excess water will block the air passage and even cause unexpected shutdown. The continuous and stable water removal of the cold dryer can make the whole air pressure system run smoothly and reduce the possibility of sudden production accidents.
Advantages of collocation with water lubricated air compressor
the water lubricated air compressor does not need additional lubricating oil to participate in the compression process, and the compressed air itself has no oil impurities, which reduces the pollutants from the source and reduces the processing burden on the cold dryer. When the two work together, the low energy consumption characteristics of the water lubricated air compressor itself, coupled with the simple operation principle of the cold dryer, the overall system can not only stably output dry and clean compressed air, but also control the overall energy consumption, and the cost of long-term operation is lower.
