CGD compressed air blast regeneration dryer

CGD compressed air blast regeneration dryer 

The blower regeneration dryer is a kind of energy-saving compressed air drying device. Its function is to remove the moisture in the air through the adsorption purification principle, so as to achieve the purpose of drying the air.

The blower regeneration dryer is composed of two alternately used adsorbers, an electric heater, a closed blower, a set of switching valve and a set of control system.

Technical Indicators

Air handling capacity: 20-500n ㎥ / min

Working pressure: 0.6-1.0mpa (1.0-3.0mpa products can be provided according to user requirements)

Air inlet temperature: ≤ 40 ℃

Dew point of product gas: ≤ - 30 ℃ -- 60 ℃ (atmospheric dew point)

Control mode: microcomputer automatic control

Working cycle: 4-6h

Regeneration gas consumption: ≤ 1-3%

Working Principles

The basic principle of the air blast regeneration dryer is that when the compressed air passes through the fixed adsorption bed layer of the adsorber, the porous surface of the adsorbent can selectively adsorb some components, and the water in the air is adsorbed in the adsorbent hole to achieve the purpose of drying the air. When the adsorbent works for a certain period of time, the adsorption reaches the saturation equilibrium, and it needs to regenerate the adsorbent with hot air to restore the adsorption capacity of the adsorbent. Because the adsorbent can be adsorbed and recycled, the blower regeneration dryer can operate safely and reliably for a long time.

Technical Features

Fixed bed arrangement is adopted. The bed layer is equipped with activated alumina with excellent draught and special for air drying.

The w gate is automatically switched by PLC, the working state is displayed by liquid ft text, and the whole process is monitored in real time.

Adopt 4-hour long-term switching.

Ring block air is used in heating period of regeneration gas source and self dry air is used in cooling period to save regeneration gas consumption.

This is a low pressure dry weight.

The regeneration heat source is electrically heated.
