Biographie Original Title: Introduction to Air Dryer of Air Conditioning System in Rail Train Chengdu Jinniu Refrigeration Network The basic principle of the air dryer is that the adsorption process is an equilibrium reaction, that is, the humidity between the adsorbent (desiccant) and the compressed air in contact with it tends to be balanced, and when the compressed air with high relative humidity contacts with the surface of the adsorbent, because the adsorbent has a large number of micropores, the contact area with the air is large. The adsorbent can adsorb a large amount of water vapor molecules of the compressed air quickly to achieve the purpose of drying the compressed air; The regeneration process is also an equilibrium reaction. The purge gas used for adsorbent regeneration is obtained by expanding the compressed air with higher pressure. During expansion, the air volume increases and the pressure decreases, and the relative humidity of the purge gas obtained is lower, so it is easy to "take away" the adsorbed water vapor molecules on the adsorbent, so that the adsorbent can be restored to a dry state to achieve the purpose of regeneration. It is characterized by adsorption under pressure and regeneration under atmosphere or negative pressure. Therefore, for any kind of adsorbent,50l rotovap, the relationship between it and the adsorbed water vapor is that the lower the temperature and the higher the pressure, the more water will be adsorbed per unit of adsorbent, and vice versa. Its principle is simply called "pressure adsorption and heatless regeneration". Commonly used adsorbents are: silica gel, alumina, activated carbon and molecular sieves. Chengdu Jinniu Refrigeration Network The basic principle of the air dryer is that the adsorption process is an equilibrium reaction,jacketed glass reactor, that is, the humidity between the adsorbent (desiccant) and the compressed air in contact with it tends to be balanced, and when the compressed air with high relative humidity contacts with the surface of the adsorbent, because the adsorbent has a large number of micropores, the contact area with the air is large.

Single tower air dryer 1. Structural composition Single-tower (also called single-cylinder) air dryer is a kind of dryer without heat regeneration, and its structure is shown in Figure 2-11. It is characterized in that the adsorption and regeneration of the adsorbent are carried out in the same drying cylinder. It is composed of oil-water separator, drying cylinder, drain valve, electro-pneumatic valve, regeneration air cylinder and silencer. In the oil-water separator, there are many "Raschig" rings (a small cylinder with seams made of aluminum or copper sheets), and the dryer is a large mesh-like cylinder filled with granular adsorbent.

Twin-tower air dryer Compared with the DC drive vehicle, the air compressor selected for the AC drive vehicle has a smaller displacement, and the gap between its stops cannot meet the time required for the regeneration of the single-tower dryer, so the double-tower air dryer is selected. The dehumidification principle of double-tower (also known as double-drum) air dryer is exactly the same as that of single-tower, except that it is equipped with two drying towers that take turns to dehumidify, which can continuously output dry compressed air. Three. Membrane Dryer (I) Function, structure and working principle of dryer system The dryer system comprises a membrane dryer and a front three-stage filter. Pre-filter: The dryer system is provided with a three-stage pre-filter which is a mechanical steam-water separator in turn; A precision filter with a filtration precision of 1 μm; Ultrafine filter with a filtration precision of 0.01 μm. Working Principle of Dewatering Membrane of Membrane Dryer Drying process of film Factors Affecting the Drying Effect of Membrane Dryer Air flow rate: fast air flow rate, high flow rate, high air pressure.
Air pressure: the higher the pressure is, the drier the blowback air is. Inlet temperature: the lower the dew point of the inlet pressure, the drier the outlet air. Blowback amount: the larger the blowback amount is, the drier the outlet air is. Thank you for reading this message.
