These three factors affect the drying effect of the adsorption dryer

Both compressed air refrigeration dryers (hereinafter referred to as cold dryers) or compressed air adsorption dryers (hereinafter referred to as suction dryers) are compressed air post-processing equipment, and their main function is to remove moisture in the compressed air to make Compressed air meets the standard.

　　 However, the suction dryer (such as the twin tower crane) has certain technical deficiencies, which makes the drying effect of the dryer poor. So what factors affect the drying effect of the dryer?

　　Influencing factors

　　 1. The adsorbent is broken

　　 1. The collision and friction between the adsorbents increase, the pulverization of the adsorbent is serious, and the water absorption performance is reduced;

　　2. The adsorbent dust is easy to block the muffler of the dryer and the post-pipe filter, resulting in a decrease in the adsorption of the filter.

　　 2. Uneven air distribution

　　Under normal circumstances, the intake pipe of the suction dryer is much smaller than the adsorption cylinder. Under the combined action of the initial pressure and speed of the compressed air, the airflow tends to pass through the packing in the container in a concentrated manner, and the gas distribution is uneven.

　　 At this time, a considerable part of the filler cannot be fully utilized, and the dead angle of adsorption is formed, which greatly reduces the utilization rate of the adsorbent and the adsorption efficiency.

　　 3. The adsorbent is not packed tightly

　　 In the adsorption tower with large capacity and deep, and the molecular sieve and alumina have different structure sizes, it is very difficult to achieve uniform and compact packing.

　　 If the filling is uneven and not tight, the "tunneling effect" will be serious and the drying effect will be affected.

　　 Once the tunnel is formed, the passing speed of compressed air will increase, and the water will be completely absorbed before the compressed air has passed, resulting in a significant decrease in the adsorption effect and an increase in dew point.
