TY series waste heat regenerative dryer is a new type of adsorption dryer. It neither belongs to thermal regenerative nor to no regenerative regenerative. It belongs to variable temperature sorption. It uses the heat of high temperature exhaust of air compressor to directly heat regenerating desiccant. The sorbent is completely regenerated, even if it is used in a low pressure condition of 0.35 MPa. As long as the load rate of the compressor is not less than 70%, the drying device can work reliably and the dew point of the product gas can reach below -42°C. Therefore, it can make full use of its own energy and have energy-saving effects. The electric heater of the micro heat regenerative dryer has been eliminated, and since there is no gas consumption during heating and regeneration, the waste heat regenerative compressed air dryer is a new type of energy-saving compressed air drying equipment.

The TY series waste heat regenerative adsorption dryer manufactured by our company is controlled by PLC automatic control. The standard cycle is 8 hours.

The final exhaust gas of the 110°C high-temperature compressor enters the dryer A tower through the V2 valve, performs desorption of the adsorbent in the A tower, cools to 42°C through the V8 valve into the cooler, and the gas enters the gas-water separator, separating the water Drain valve. The separated gas enters the B tower through the V11 valve. Under the effect of desiccant adsorption, the gas is further dewatered and dried. Then, the gas is output through the V7 valve and passes through the dust filter to get the finished product gas.

After desorption of Tower B, it enters the cooling and dry regeneration stage. At this time, the process switching valve V1 is opened, and the waste heat recovery valve V3 is closed. The gas is directly sent to the cooler and cooled to 42°C. Then it enters the gas-water separator and the water is separated. Drain valve discharge. The separated gas enters the A tower through the V10 valve and is output through the V6 valve. At the same time, the dry regeneration valve V5 and the regenerative discharge valve V13 are opened, allowing about 1.5% of the gas dried in the A tower to pass through the manual adjustment valve V4. After depressurization and expansion, it flows through the B tower to cool down the B tower adsorption bed and further dry it for use in the next half cycle, and then exhausted to the atmosphere through the muffler. When the tower B has cooled down, the regenerative exhaust valve V13 is closed, and pressure is increased through the dry regenerative valve V5 to double-column pressure balance to prevent dew point and peak pressure during switching. At this time, the first half cycle of the drying device is completed, and the double towers are switched into the second half cycle.

After the desorption of Tower A's residual heat, it enters the cooling and drying regeneration stage. At this time, the process switching valve V1 is opened, and the waste heat recovery valve V2 is closed. The gas directly enters the cooler and is cooled to 42°C. Then it enters the gas-water separator and separates the water. Drain valve discharge. The separated gas enters the B tower through the V11 valve and is output through the V7 valve. At the same time, the dry regeneration valve V5 and the regenerative exhaust valve V12 are opened so that approximately 1.5% of the gas after the B tower is dried passes through the manual adjustment valve V4. After depressurization and expansion, it flows through A tower, cools down the adsorbent bed of A tower, and is further dried and regenerated for use in the next half cycle, and then discharged into the atmosphere through the muffler. When the tower A is cooled down, the regeneration discharge valve V12 is closed, and pressure is increased through the dry regeneration valve V5 to double tower pressure balance to prevent dew point and peak pressure during switching. At this time, the first half cycle of the drying device is completed, and the double towers are switched into the second half cycle.

1.Continuous air supply: Unique measures are taken to ensure that there is no air-breaking phenomenon when the adsorption tower is switched, and at the same time, the impact of instantaneous airflow on the adsorbent during switching is avoided.

2.The special design of the adsorption tower: The special diffusion structure at the bottom of the adsorption tower and the special filling method to fill the adsorbent can eliminate the tunneling effect and the mutual friction between the adsorbents.

3.Adopt the world famous brand products to ensure the stability of operation: The use of internationally famous brands of control valves and shut-off valves, so there is a major guarantee in the use of quality and safety and reliability.

4.The use of high-performance sorbents: the use of custom sorbents, its performance is recognized by the industry.

5.The use of high-performance degreasing dust filter: the use of imported filter material made of efficient water removal, degreasing dust filter to ensure that the adsorbent is not liquid water, oil pollution failure.

6.High-performance rear cooler: The efficient rear cooler can stably reduce the high-temperature compressed air to the designed temperature to ensure the efficient and reliable operation of the whole machine.
