Product Introduction

The blast heat adsorption dryer belongs to the heating regeneration dryer. Its working principle is to use a blower to extract ambient air, and then regenerate the desiccant in the adsorption tower after heating, avoiding the gas loss of the micro-heat regeneration adsorption dryer during the heating stage. Compressed air enters the fixed adsorption bed of the adsorber, and the porous surface of the adsorbent can selectively adsorb certain components to adsorb the moisture in the air into the adsorbent cavities to achieve the purpose of drying the air. After the adsorbent has worked for a certain period of time, the adsorption reaches saturation equilibrium, and hot air is needed to regenerate the adsorbent to restore the adsorption capacity of the adsorbent. Since the adsorbent can be adsorbed and regenerated for recycling, the blast regeneration dryer can operate safely and reliably for a long time.

How it works

The process flow of the blower regeneration dryer is that the compressed air from the compressor system passes through the pre-precision filter (oil removal) to initially remove the trace oil, liquid water and other media carried in the gas, and then enters the machine system. First, the compressed air passes through the air inlet valve to enter one of the adsorbers for adsorption and drying to remove moisture, and then passes through the air outlet valve to the post-precision filter to filter out the very small amount of adsorbent dust that may be brought out by the adsorber, and obtain dry air to leave the system for subsequent processes. At the same time, the other adsorber enters the regeneration state. The regeneration process mainly consists of heating and cooling. During the heating period, the regeneration gas source uses ambient air. Its flow path is after being pressurized by the blower, and then enters the electric heater through the gas check valve to heat the air to 190℃. Then the heated regeneration gas enters the adsorber through the regeneration gas inlet valve to heat and desorb the saturated adsorbent. The water desorbed by the heated adsorbent is brought out of the system by the regeneration gas. After the regeneration treatment, the adsorbent regains the re-adsorption capacity. After the regeneration gas comes out of the adsorber, it passes through the regeneration gas outlet valve, the venting muffler, eliminates the noise, and is discharged into the atmosphere. When the regeneration heating is over, before the adsorber is switched, dry air is needed to cool the adsorption bed to obtain a stable dew point. The regeneration gas source during the cooling period is also ambient air, and the PLC control is notified to switch automatically. The flow path is from the blower through the post-cooling cooling water, through the regeneration gas cut-off valve, the regeneration gas regulating valve, and the throttling orifice plate to reduce the pressure to a very low regeneration pressure, and then enters the adsorber to cool the adsorption bed.
