air compressor after treatment dryer knowledge:

what is adsorption? How does adsorption occur?

Adsorption is the phenomenon that the concentration of a substance changes automatically at the interface of two phases.

All solids have varying degrees of the ability to adsorb molecules, atoms, or ions of the surrounding medium to their own surfaces. From a thermodynamic point of view,

the reason why the solid surface can adsorb other media is that the energy that the solid surface has had-physically called "surface free enthalpy"-has the tendency to adsorb other substances to reduce its own surface energy.

What is an adsorbent? What is an adsorbate?

Substances that have a significant adsorption effect on a particular medium are called "adsorbents". The adsorbed material is called "adsorbate". Under certain conditions, the larger the surface area of the adsorbent, the stronger its adsorption capacity. Therefore, in order to increase the adsorption capacity of the adsorbent, it is necessary to increase the adsorption as much as possible.

③ What is a compressed air adsorption dryer? What are its characteristics?

Compressed air dryer is the use of adsorbent at room temperature on the water vapor in the air has a large adsorption capacity made of compressed air drying equipment. The characteristic is that the compressed air treated by the adsorption dryer has lower dew point, less water content, but more energy consumption.

What are the commonly used adsorbents for adsorption dryers?

Commonly used adsorbents are: silica gel, activated alumina, molecular sieve.
