Plate Heat Exchange Type Air Dryers

The refrigerated dryer is based on the principle of freezing and dehumidifying, forcing the compressed air containing a large amount of saturated water vapor to cool down, and keeping the pressure of the compressed air basically unchanged, lowering the temperature of the compressed air, so that a large amount of water vapor in the compressed air can be in a supersaturated state, and in the saturated state, water vapor condenses into liquid droplets, entrains dust, and separates moisture and dust through a vapor-water separation device and discharges it through an automatic drain, thereby achieving the purpose of freezing and dehumidification.

MAIN FEATURE

Good heat exchange performance, saving cooling power consumption

The pre-cooling and evaporation system adopts aluminum plate-fin heat exchanger design, the heat exchange performance is far greater than the conventional shell and tube heat exchanger, and the limit temperature difference between the air inlet and outlet can reach 2 X), reducing The required cooling capacity can better

ensure the treatment effect and reduce the energy consumption of the refrigeration dryer.

Large heat exchange area, small air flow gap

The aluminum plate-fin heat exchanger is constructed by overlapping multiple corrugated fins and baffles. The

fin spacing is very small and the number of layers is large, so the heat exchange area is large. The heat

exchanger has a compact structure, but the fins airflow gap between is very small. Therefore, its application

method is different from the shell and tube heat exchanger, and it is necessary to consider avoiding the risk of

“ice blocking”.
