                    Micro hot dryer

                    Micro hot dryer

                    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.
                    1. working principle
                    The TR micro-thermal regeneration adsorption dryer adopts the principle of variable pressure variable temperature adsorption to achieve the purpose of drying compressed air.
                    2. Process flow (see figure)
                    TR micro-thermal regeneration adsorption dryer, schematic diagram of the process (Figure A tower as a tower B tower as a desorption tower).
                    ① Adsorption process
                    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.
                    ② Desorption process
                    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.
                    ③ Recycling process
                    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.
                    3. The main components of superiority
                    TR digital electronic intelligent controller

                    Adsorption cartridge
                    ▲ A large capacity adsorption tower reduces the gas flow rate and ensures the stability of the outlet dew point.
                    ▲ The refueling port is flanged to replace the adsorbent and is equipped with a washable stainless steel diffuser to prevent "tunneling" from making the adsorption more uniform and effective.
                    ▲ The interior of the adsorption tower is treated with dry powder epoxy resin.
                    ▲ 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.
