Non-thermal adsorption dryer

Non-thermal adsorption dryer

The non-thermal regeneration adsorption dryer is a kind of dehumidification purification device that uses the non-thermal regeneration method (no external heat source) to adsorb and dry compressed air based on the principle of pressure swing adsorption.

The non-heat drying machine is a high-quality model developed by our company on the basis of digesting and absorbing advanced technology of similar foreign products in recent years, considering the actual situation of domestic users, and carefully designed and developed. Under normal operating conditions, it can remove air The dew point pressure will be below -40°C, and as low as -70°C, it can provide oil-free and water-free high-quality compressed air for a few applications that have high requirements on air quality, especially suitable for cold northern regions and Other gas-using occasions where the ambient temperature is lower than 0°C.

The heatless absorption dryer adopts a double tower structure. One tower absorbs moisture in the air under a certain pressure, and the other tower uses a part of dry air slightly higher than atmospheric pressure to regenerate the desiccant in the adsorption tower. After a certain period of time, the two towers switch To ensure continuous supply of dry compressed air.

Unique computer control system, visually displays the running status of the dryer, and has multiple alarm protection functions and a DCS remote control interface to ensure trouble-free use.

The actuator adopts pneumatic angle seat valve and pneumatic butterfly valve, and the pneumatic control system adopts deep dry air source and then filtered to ensure reliable action and avoid valve leakage.

Accurately calculated the height and diameter of the adsorption tower and the results of the experiment, and really grasp the important parameters such as flow velocity, heat and mass transfer, and avoid excessive wear of the adsorbent and tunnel effect.

Professional program-controlled design, small air pulse and air pressure fluctuation, effectively reduce the outlet air dust and the noise of the regeneration air flow.

Convenient and practical cycle time mode and energy-saving economic mode. Regenerative air volume and time program can be adjusted to adapt to various actual use conditions and outlet dew point requirements.

The support base is stable and beautiful in appearance, easy to install, use and maintain.
