Energy Saving Technology of Thermal Regenerative Compressed Air Dryer by Regenerates Adsorbent with Residual Heat

According to the characteristic of the compressed air dryer located at the same place with the air compressor, for the large capacity thermal regenerative compressed air dryer that the absorbent is regenerated by an electric heater, this thesis puts forward an energy saving method, which use the residual heat of compressed air from the grade II outlet of air compressor to preheat the regeneration airflow. The regenerate process is described and the power of electric heater is calculated. The energy can be saved about 40% by using this method and the complexity of the equipment doesn´t increase.
