Product Detail
- The DC series self-activating, heatless dryers, DC 121-134 remove moisture from compressed air. They contain two pressure vessels or towers, each containing a quantity of desiccant. One tower dries the air, while the other is being reactivated.
- The 'heatless' principle of regeneration is based on the physical property of the desiccant, given as Delsorb as one of its kind in Asia and approved by all major consultants, which liberates the adsorbed water vapour, if air with a low water vapour pressure is passed through it.
- For this, a percentage of dried compressed air is expanded, as a result of which it contains little water vapour per volume. This purge air flowing through the adsorber helps liberate water vapour from the desiccant.
- The heat of adsorption during drying period causes a temperature rise of the desiccant which stimulates the liberating of water vapour and so the regeneration.
- The vapour adsorbed during the drying cycle will be desorbed and discharged to the atmosphere during the reactivating cycle.
Heat of Compression Dryers
The wet hot air enters the dryer through 3 way valve (V-1), where it change the direction diret towards 4 way ball valve V-2 in heating cycle and towards 4 way ball valve thru pre cooler in cooling cycle.
Regeneration
Heating
The regeneration of desiccant is carried out by hot air. This air passes through port (1-2) of 3 way valve (V-1) enters the 4-way valve (V-2) wherefrom it is directioned to the adsorber tower (ADS-1), which is in regeneration mode, through the port (3-4). The hot air heats the desiccant bed and expels the moisture present in desiccant. The air after passing through the ports (4-1) of 4-way valve (V-3) enters into the regeneration cooler (RC-1). The air gets cooled to inlet air temperature in the cooler and enters the moisture separator for moisture separation. After moisture separation, it enters into adsorber tower (ADS-2) via ports (1-2) of 4 way valve (V-1) for adsorption (Drying).
Cooling
When the desiccant gets heated up by hot air it is to be cooled upto drying inlet air temperature for effective drying. For cooling, air passes through port (1-3) of 3 way valve (V-1) get cooled upto 40°C and moisture separated, while passing through pre cooler and moisture separator and enters the 4-way valve (V-2) wherefrom it is directioned to the adsorber tower (ADS-1), which is in regeneration mode, through the port (3-4). The air cools the desiccant bed and expels the moisture and heat present in desiccant. The air after passing through the ports (4-1) of 4-way valve (V-3) enters into the regeneration cooler (RC-1). The air gets cooled to inlet air temperature in the cooler and enters the moisture separator for moisture separation. After moisture separation, it enters into adsorber tower (ADS-2) via ports (1-2) of 4-way valve (V-1) for adsorption tower (ADS-2) via ports (1-2) of 4 way valve (V-1) for adsorption (Drying).
Adsorption
The full air flow passes through the 4-way valve (V-2) through the port (1-2) and enters the adsorber tower (ADS-2) wherein it is dried while passing through the desiccant bed. This dried air enters the after filter (AF-1) after passing through the port (2-3) of 4-way valve (V-3). The after filter removes the desiccant dust and after cooler maintain desired outlet air temperature and supplies dry, filtered air at the outlet of dryer.
This way when one desiccant bed dried the air. Other bed gets reactivated and vice-versa this change over is achieved by the help of PLC.
