Normal Temperature Water-Cooled Freezing Dryer

The condenser of the refrigeration system is cooled by cooling water. It is mainly used in the occasion of good water supply conditions, high inlet temperature and large air treatment brightness, because it is less affected by ambient temperature factors, so the outlet air dew point is more stable, mainly suitable for users who require stable air dew point and high ambient temperature. The compressed air enters the air precooler to precool and remove part of the water, and then enters the air cooler to reduce the temperature to 2 °C (dew point temperature), the water in the air precipitates at this temperature, separates by the air-water separator and discharges the water by the automatic drain valve, while the dry low-temperature air enters the air precooler, and then heats up with the untreated compressed air and heats up and output, that is, the treated dry air.

The compressed air first enters the precooler (20, 21) for preliminary cooling, and then introduces the air-to-air heat exchanger (recuperator) (1), which is further cooled by the cooled exhaust air and discharges the condensed water out of the machine. It then flows into the gas-to-refrigerant heat exchanger (evaporator) (2) and is further cooled by the refrigeration system. After the compressed air is gradually cooled by the precooler (20, 21), reheater (1) and evaporator (2), the water vapor in the air condenses into liquid water beads, and the liquid water is separated by the gas-liquid separator (3). The drying cooling air passing through the gas-liquid separator (3) is heated up as it leaves the dryer through another process of the gas-to-air heat exchanger (recuperator) (1).

1.Use industrial circulating water as the cooling medium of the refrigeration system, suitable for use in high-temperature environments; 

2. The heat exchanger adopts counter-flow design, which has high heat exchange efficiency and small volume; 

3. The refrigeration compressor adopts fully enclosed or semi-enclosed refrigeration compressors from Panasonic, Boyang and other companies, with stable operation, low noise, high COP, reliable performance, and long power saving life; 

4. The refrigeration control components are all made of the world's most advanced Danfoss from Denmark, Emerson and Poland 

5. The steam and water separator adopts a three-stage separation method: direct collision separation + low-speed centrifugal separation + stainless steel wire mesh defogging separator, which separates 99.9% of the liquid water from the cooled compressed air, the secondary evaporation of textile moisture, and the low dew point quality of the finished packaging gas.



Refrigeration system is fully equipped:The key components of the machine are imported brand products, which ensure the reliable operation and life of the system while ensuring the processing effect. The refrigeration and air systems are accurately calculated by experts, and the design parameters retain more than 20% of the margin.

Electronic drainer:The electronic timed drainer is adopted, imported technology brand, and the enlarged electronic automatic drainer is selected to eliminate the hidden dangers caused by blockage.


3


The gas-liquid separation is fast:The use of filtered gas-liquid separator, equipped with foreign HANKISON filter element, the gas-liquid separation effect is fast, avoiding the secondary evaporation of moisture, ensuring the important role of the drying effect of the cold dryer, it is higher than the cyclone separator separation efficiency, the separation efficiency reaches 99.99%.
