Air Dryer Desiccator

Design Feture

A new generation of absorbing type desiccator, integrate the advanages of change pressure absorbing and change temperature absorbing. It absorbs under the normal atmospheric temperatureand high evaporation partial pressure (working); resolve under relatively high temperature and lowevaporation partial pressure (regenerating); that is the moisture content which the desiccant absorbedduring the absorbing process is thoroughly get rid of in the regenerate process by the joint effect of the heat diffusion and low partial pressure of the high quality regenerated air (heated and dried air).

Absorb: the humid air enters A drier via the down pipe system a1, flow through the desiccant bedfrom bottom to top, the dried air is discharged from the up pipe.

Regenerate/blast: a few dried air (about 7%) enters the heater to be heated after being decompressed while flowing through the regenerated air regulation valve of the up pipe system. This portion of hot air (refered as regeneratd air) enters B drier, resolves and regenerated air is discharged into the armosphere after flowing through the B2 valve of the down pip system and silence.

Pressure equalizing: after the regenerating of desiccant, the B2 valve will shut. B drier gradually riseto the online work pressure, shift accurately.

Shift: B1 valve of the down pipe system will open, A1 valve shut, A2 valve open, the shifting processof the A,B drier is compleated. B drier begins absorbing, A drier relieve pressure and regenerate. The working sequence, working period and heating temperature are all automatically controlled by the controller.

Changing pressure absorbing

Short-term absorbing circulation, isothermal manipulation, 100%  preserve the absorbingheat, good heat desorption effect.

The cycle can be edited at the scene, and is set 10 (or4) min when leaving the factory

Through double accounts of heat and water, bed resistace is low, the touching period of airflow and the desiccant is more than 5 seconds.

The desiccant fill capacity is abundant, guarantee that the dew point of the outlet air is the lowest

Full electronic programmable controller, the Human-Computer Connector is very friendly, showthe working status of the double tower automatically and continuously

Accurate movement, stable performance, convenient manipulation

The inner wall of the pipe body has boon cool galvanized, so it can not be rusted in ten years

Inlet air/regenerate valve is 4-value or 3-valve structure, reliable performance, the service lifespan of the valve is as long as 500 thousand motions

Optimized valve form, which ensures the feasibility and convenience of repair and replace at the scene

High precision two-way regenerated air regulation valve, which guarantee a stable regenerated air flow and a regenerated pressure as low as critical pressure

The humidity content of the regenerated outlet air is hold at sub-saturation, so there will be bodew fall at the silencer and exhaust passage.

Low load regenerated energy-saving control and dew point online testing connector are setaside in advance
