Introduction of micro heat regeneration adsorption dryer

The non-thermal regeneration suction dryer uses the compressed air pressure change, adsorption under high moisture pressure, and desorption under low moisture pressure to regenerate the adsorbent. On the basis that the regeneration gas discharge temperature is equal to the compressed air temperature, it is obtained The conclusion that the regeneration gas consumption is equal to "one part of the pressure" into the tower. So can heating the regeneration gas temperature reduce the consumption of regeneration gas?

　　 In compressed air purification equipment, there is a micro-heat regeneration adsorption dryer that uses this principle to work.

Introduction of micro heat regeneration adsorption dryer

　　 Micro-heat regeneration dryer uses the low dew point compressed air provided by the heating machine to desorb and regenerate the adsorbent. It has no exact requirements for the gas temperature, but it is generally far lower than the low z* desorption temperature required for the adsorbent "temperature swing adsorption", so in essence, the "microthermal" regeneration still belongs to the range of pressure swing adsorption. The purpose of heating regeneration gas is to reduce the consumption of regeneration gas.

Since the low dew point regeneration gas has provided the necessary environmental conditions for adsorbent desorption, it is not important to the dryer to how much a limited increase in the regeneration gas temperature can accelerate the desorption rate, but the exhaust temperature of the regeneration exhaust gas is directly related When it comes to the consumption of regeneration gas; the regeneration tail gas with higher temperature can absorb more water vapor, and the regeneration gas volume can be reduced under certain conditions of water volume; otherwise, the regeneration gas volume will increase.

　　 Because the "micro-heat" regeneration dryer uses an external heat source to heat up the regeneration gas, and after desorption, it must be cooled with compressed air at room temperature and low dew point, so the "micro-heat regeneration" also consumes part of the air.
