Background

The heatless regeneration adsorption dryer is an advanced device which dries compressed air by filling alumina or molecular sieve with high water absorbability by utilizing the pressure swing adsorption principle, and can usually dry the compressed air to the dew point of-40 to-70 ℃; the heatless regeneration dryer is designed based on the pressure swing adsorption principle, that is, the adsorbent which is saturated with adsorbed moisture under the pressure state is rapidly depressurized to the atmospheric pressure, at the moment, the adsorbed moisture is automatically desorbed to realize the regeneration of the adsorbent, and the desorbed moisture is diffused outside the machine; the method of regenerating by using the above principle is called as a pressure drop method, and the pressure drop method is also called as a heatless regeneration method because the adsorbent is regenerated by using the heat generated by the adsorbent in the adsorption process and introducing a small part of dry air into the adsorbent to be regenerated.

The heatless regeneration dryer adopts the technology of double-tower pressure swing adsorption and heatless regeneration, and the working principle is that one adsorption tower carries out adsorption drying under the working pressure, and simultaneously, the other adsorption tower utilizes partial self-drying gas and reduces the pressure to be close to the atmospheric pressure to regenerate the adsorption tower as the regeneration gas, and double-tower switching is carried out at fixed switching time, so that the drying gas is continuously provided.

2. Minimum regeneration gas consumption: the tower body can store 98% of adsorption heat, keep the high temperature of the regeneration gas and improve the regeneration capacity; drying and regeneration flow in opposite directions, so that energy is not wasted when wet air flows through the dry adsorbent.

3. The adsorbent has long service life: the detachable stainless steel diffuser with unique design uniformly distributes gas in the tower, and avoids the abrasion of the adsorbent after channeling; the slow and effective re-pressurization does not cause the adsorption bed to move to generate abrasion, and the fluctuation of the downstream pressure is eliminated; the high-quality adsorbent is selected, the automatic pressurizing function, the advanced filling technology and the airflow distribution technology can ensure that the drying agent has long service life.

4. The operation is easy: the advanced microcomputer control system has the functions of automatic timing, automatic switching, working time setting, fault alarming and the like; and dynamically displaying the operation state. RS485/RS232 and a linkage interface can be provided, and remote communication, centralized control and air compressor joint control can be carried out.

5. Easy maintenance: the adsorbent filling hole and the discharge port are independent, so that the replacement is easy; the detachable stainless steel diffuser is convenient to clean; the dryer can be provided with a bypass pipeline, and the dryer can be maintained without stopping the air compressor or influencing production.

6. Safety: each tower is provided with a safety valve; a heavy-duty exhaust muffler to minimize noise; design and manufacture to meet pressure vessel specifications.

7. Reliable: the high-quality cut-off valve and the high-quality electromagnetic valve are selected, so that the action is accurate and the performance is reliable; the pipeline flanges are butted, no leakage exists, and the assembly and disassembly are easy.

8. The regeneration air consumption is adjustable, and the energy-saving and dew point adjusting functions are achieved.

9. A dew point monitoring control system can be optionally installed according to requirements.
