The micro-thermal regeneration adsorption dryer is an adsorption dryer which is developed by absorbing the advantages of a heat adsorption regeneration dryer and a non-thermal regeneration adsorption dryer. It avoids the disadvantages of short switching time and large regeneration gas consumption of the no-heat regenerative adsorption dryer, and also overcomes the disadvantage of the large power consumption of the thermal regenerative adsorption dryer. The regeneration gas of the micro-thermal regeneration dryer regenerates the desiccant after the temperature is increased, which can not only improve the regeneration effect, but also reduce the regeneration gas consumption and the like.

The TR micro-thermal regeneration adsorption dryer adopts the principle of variable pressure variable temperature adsorption to achieve the purpose of drying compressed air.

TR micro-thermal regeneration adsorption dryer, schematic diagram of the process (Figure A tower as a tower B tower as a desorption tower).

When using Tower A as an adsorption (drying) tower, the intake valve Z2 and the exhaust valve Z3 should be closed first, and the valve Z1 should be opened. Undried compressed air entering from the gas inlet flows through Z1 to Tower A. In the lower part, the moisture in the moist air is adsorbed and the dry compressed air flows out of the upper part of the A tower. About 97% of the dry air passes through the check valve H and flows out of the gas outlet.

When desorption (regeneration) of the tower B, about 3% from the A tower, the dry air passes through the regulating valve J and enters the heater Q to warm up and then flows through the tower B, blowing away the adsorbed water. The regeneration gas is discharged through the muffler S through the opened exhaust valve Z4.

In the second half of the cycle, Tower A is converted to the desorption process, Tower B is converted to the adsorption process, and the switching period is 120 to 240 minutes (can be designed as required). The action of each valve is displayed on the front panel of the controller.

After many years of research and development, the controller has been carefully designed, and has drawn on advanced technology from both home and abroad. The new generation of intelligent control instrument developed has reached the international advanced level.

▲ Meet GB150-1998 specifications and attach safety valve.

At present, there are three types of adsorbents used for compressed air drying: silica gel, activated alumina, and molecular sieves. Silicone is used less often because it will break in liquid water. Molecular sieves have a high cost, but below 20% of the relative humidity, they have a good adsorption capacity for trace moisture. Activated alumina has the advantages of fast adsorption speed, but it has poor adsorption capacity under trace moisture adsorption. The adsorbents in the TR series adsorption towers use molecular sieves.
