Product Introduction
1. Heatless Regeneration Adsorption Dryer Working Process
BOLY heatless regeneration adsorption dryer utilizes pressure swing adsorption regeneration cycle, allowing compressed air to alternate through two drying towers A and B filled with adsorbent. One tower adsorbs water vapor under high partial pressure (working pressure), while the other tower regenerates under low partial pressure (atmospheric pressure), switching according to a set time program.
Adsorption: Moist air enters drying tower A through valve A1 from the lower pipe diameter, flowing upward through the adsorbent layer. The dried air is discharged from the upper piping system.
Regeneration: A portion of the dried air (about 14%) passes through the upper piping regeneration gas control valve into drying tower B. The depressurized dried air (called regeneration gas) flows downward to desorb and regenerate the adsorbent in tower B, restoring its drying capacity. The regeneration gas is discharged to the atmosphere through valve B2 and a silencer at the lower piping.
Pressure Equalization: After adsorbent regeneration is completed, valve B2 closes, and drying tower B is pressurized to the online working pressure, preparing for switching.
Switching: Valve B1 in the lower piping opens, valve A1 closes, valve A2 opens, completing the switch between drying towers A and B. Tower B enters adsorption, and tower A depressurizes for regeneration. The working sequence and time are automatically controlled by the controller.
2. Micro-heat Regeneration Adsorption Dryer Working Process
BOLY micro-heat regeneration adsorption dryer combines the advantages of pressure swing adsorption and temperature swing adsorption. The moisture adsorbed by the adsorbent during adsorption is thoroughly removed during regeneration by the combined effects of heat diffusion from the regeneration gas (heated dry air) and low pressure.
Adsorption: Moist air enters drying tower A through valve A1 from the lower pipe diameter, flowing upward through the adsorbent layer. The dried air is discharged from the upper piping system.
Regeneration: A small amount of dried air (about 7%) passes through the upper piping regeneration gas control valve, is depressurized, then heated by a heater. This heated air (called regeneration gas) enters drying tower B to desorb and regenerate the adsorbent, restoring its drying capacity. The regeneration gas is discharged to the atmosphere through valve B2 and a silencer at the lower piping.
Pressure Equalization: After adsorbent regeneration is completed, valve B2 closes, and drying tower B is pressurized to the online working pressure, preparing for switching.
Switching: Valve B1 in the lower piping opens, valve A1 closes, valve A2 opens, completing the switch between drying towers A and B. Tower B enters adsorption, and tower A depressurizes for regeneration. The working sequence and time are automatically controlled by the controller.
Product Features
1. Calculated by both thermodynamics and hydraulics, the tower bed resistance is low, and the contact time between compressed air and adsorbent is greater than 5 seconds, ensuring the dew point requirement of the outlet product air.
2. 30% adsorbent reserve to compensate for natural aging of the adsorbent, ensuring drying effectiveness.
3. Large diffuser ensures uniform airflow through the adsorbent layer, eliminating channeling.
4. Fully electronic programmable controller with user-friendly interface, automatically and continuously displays dual tower status, stable performance, and easy operation.
5. Inner wall of the tower is cold galvanized for rust prevention, ensuring no corrosion for 10 years.
6. Long adsorbent service life, generally over five years under normal use.
7. Inlet/regeneration valve system with 4-valve or 3-valve structure, reliable operation, valve life up to 500,000 cycles.
8. Regeneration gas outlet moisture content controlled in sub-saturation state, no condensation concerns in silencer and exhaust passage.
9. Reserved interfaces for low-load regeneration energy-saving control and online dew point detection.
