The suction dryer integrates the advantages of pressure swing adsorption and temperature swing adsorption. It adsorbs (works) at normal temperature and high steam partial pressure; decomposes (produces) at higher temperature and low steam partial pressure, that is, the water adsorbed by the adsorbent during the adsorption process. In the regeneration process, it is completely removed by the combined action of the two mechanisms of thermal diffusion and low partial pressure of high-quality reproduction (dry air heating). The adsorbed wet air enters the drying tank A through the A1 valve from the lower pipe system, flows through the adsorbent bed from bottom to top, and the dried air is discharged from the upper pipe system.   System Configuration   1) Humanized design: scientific and reasonable structure design, novel appearance, elegant appearance, long-term high efficiency, stable performance, convenient operation, maintenance and maintenance, and easy installation (no foundation). 2) Using the working principle of pressure swing adsorption, the cycle period can be programmed according to the working conditions, and the factory standard setting is 10min. A variety of control modes can be reasonably selected according to customer needs, such as: PLC control, remote monitoring, dew point display and signal transmission functions. 3) The simplified inner wall is professionally treated to prevent rust, and it will not rust for 10 years. 4) Flexible and stable pneumatic valve, reliable operation and long service life. 5) The filling amount of the adsorbent is extremely abundant, and the large-capacity desiccant bed ensures sufficient contact time between the air and the desiccant, so that the desiccant can fully absorb water and achieve a stable outlet dew point. Ensure the stability of the dew point of the outlet air and the effect of removing water. 6) High-quality mufflers can effectively reduce product noise, have pressure protection function, and improve product safety. 7) Maintaining a proper flow rate of the air in the adsorption cylinder can not only ensure that the compressed air is fully contacted with the adsorbent, but also prevent the adsorbent from moving and pulverizing. 8) The product is uniquely designed, the airflow pulse is small, the air pressure is stable without fluctuation, the crushing of the adsorbent is greatly reduced, and the outlet gas contains less dust. main feature 1. The working cycle can be arbitrarily set as required 2. The regeneration gas can be precisely controlled 3. Reliable control system, strong anti-interference ability, long service life, using SSR non-contact relay, can realize precise temperature control 4. Small gas consumption, high heating efficiency and low energy consumption 5. The advanced monitoring and control system can be added as required 6. Multiple safety protection devices and multi-circulation micro-heating devices strengthen desorption regeneration with good effect. Precautions The oil content of the air entering the tower should be controlled below 0.01mg/m3, and it is necessary to install an oil remover at the air inlet of the dryer; The micro-heat regeneration suction dryer should be used under the rated temperature and pressure conditions. When the intake air temperature is higher than the intake air pressure or the intake air pressure is lower than the rated value, the capacity correction should be carried out; When the micro-heat regeneration suction dryer is used in conjunction with a piston air compressor, a pressure-stabilized air storage tank should be installed in front to eliminate the high-speed impact of the pulsating airflow on the adsorbent; Do not deliberately "energy saving" to reduce regeneration gas consumption (including regeneration gas volume and heating power); When there is a "cold dryer front", the connection between the micro-heat regeneration suction dryer and the cold dryer should be installed separately as long as the site permits, so as to reduce the air pressure drop, improve the ventilation conditions of the cold dryer and facilitate the daily operation of the dryer. maintenance and overhaul; When the air supply is sufficient, the heatless regeneration dryer should be listed as the first choice. Its comprehensive energy consumption will not be higher than that of heating regeneration, and its dew point is lower and more stable.
