A freeze-drying machine first freezes water containing substances into a solid state, and then sublimates the solid water into a gaseous state, thereby removing water and preserving the substance. In the process of compressed air drying, its freeze-drying is to reduce the temperature of the compressed air and separate the moisture in the compressed air.The working principle of a refrigerated dryer is to use a refrigerant to cool compressed air to a certain dew point, separate supersaturated wate

Even if oil-free air compressor is used, compressed air pollution will not disappear during air compression! The air in the atmosphere is naturally polluted. These include water vapor, oil vapor, liquid oil, liquid water, pipe stain/rust, water aerosol, natural gas aerosol, microorganism and air pollution. The existence of these pollutants requires air purifiers (also known as air treatment products or compressed air auxiliary products), and means reducing or completely removing pollutants in compressed air. How to handle compressed air? Many compressed air filters can be used to process compressed air to the purity level required by your application, and depending on the end use, installation of compressed air may require some or all parts or all. To control pollutants and condensate, treat compressed air according to the following three basic steps

In many chemical enterprises, food industry, medicine, electronic industry and other industries using compressed air energy, unclean compressed air will damage the whole process of other processing processes. Therefore, in order to better improve the service life and reliability of pneumatic mechanical equipment and systems, and ensure the quality of manufactured goods, compressed air should be dried and purified as much as possible.

1 What is adsorption? How does the adsorption effect occur?
Adsorption is a condition in which the content of substances is automatically changed at the two-phase page. All solids have the ability to adsorb the molecular structure, molecules or positive ions in the surrounding materials to its surface. From the perspective of thermodynamics, what the solid surface can absorb from other substances is actually the kinetic energy appearing on the solid surface, which is called "surface random enthalpy" in physics, and it can digest and absorb other components to digest and absorb its own surface energy. This is because it tends to decrease.
