The original heatless adsorption dryer works like this

According to the method of adsorbent regeneration, it can be divided into two types: heatless adsorption dryer and thermal adsorption dryer. Since the heatless adsorption dryer works by isothermal adsorption, it is also called "pressure swing adsorption". The thermal adsorption dryer works by isobaric adsorption, also known as "temperature swing adsorption". In actual use, there is also a kind of micro-heat dryer. From a formal point of view, the micro-heat regeneration dryer also heats the regeneration gas, but because it uses the regeneration gas from its own low water content drying Air, so it is also a "pressure swing adsorption" dryer.

The heatless adsorption dryer utilizes the characteristic of adsorbent to selectively adsorb certain components and adsorb the moisture in the compressed air to achieve the purpose of drying. Since the adsorbent will reach saturation equilibrium after being adsorbed for a certain period of time, it needs to be regenerated with dry gas to restore the adsorption and drying capacity.

A large amount of air discharged from the air compressor flows in from the compressed air inlet pipe and enters the operating towers of the two towers through the air valve. The moisture in it will be absorbed by the adsorbent and dried. When the air circulates to the top of the tower, all the moisture in the air is absorbed, and the dew point temperature can reach -40℃, so as to achieve the purpose of drying. The entire cycle standard takes 10 minutes, and each tower runs for 5 minutes. One tower is in the process of working (operation tower), and the other tower is in regeneration state (non-operation tower). The regeneration time is 4.5 minutes. During the regeneration process, operation A part of the dry air in the tower enters the non-operating tower through the regeneration air volume regulating valve, and the water in the tower is brought to the atmosphere through the silencer. The air consumption during operation is 12% of the equipment processing capacity.
　　

Reasonably set up the equipment pipeline structure and connect the pipes with flanges to ensure that all equipment components can be easily disassembled and repaired; the equipment bottom skid and overall structure are optimized to make the equipment simple and generous. The bottom of the adsorption tower is filled with load-bearing ceramic balls, and the reverse air supply is adopted, which can make the air flow distribution more uniform, avoid the bottom layer of adsorbent from soaking, and ensure the use effect and life of the adsorbent.
