How to save energy in the dryer in the compressed air purification system

In many industrial occasions, compressed air systems have very high requirements for the water content of compressed air, such as: chemical, pharmaceutical, spraying, power electronics and other industries; therefore, companies usually use cold dryers or suction dryers to dry compressed air. At the same time, it also produces a lot of energy loss, usually referring to electricity and regeneration gas consumption.

The energy consumption of the refrigerated dryer mainly refers to electric energy, but due to the working principle and structure, the pressure dew point of the refrigerated dryer can generally only reach 10°C. To obtain a lower pressure dew point, the power of the refrigerant compressor must be increased, thereby also increasing The loss of electrical energy.

Investigations show that most industries and pneumatic equipment require compressed air pressure dew point to be between -20°C and -40°C. However, most users in the market currently use refrigerated dryers to measure dew point between 20°C and 35°C, with inclusions A large amount of liquid water greatly shortens the service life of the equipment and increases the failure rate of the equipment.

The general adsorption dryer has two kinds of energy consumption: 1. The loss of compressed air; 2. The power consumption of regenerative heating; choosing a suitable suction dryer can greatly reduce air consumption and power consumption, and eliminate unnecessary Loss and energy saving
