Heatless modular dryer

Introduction to the heatless module series adsorption dryer:

1. The adsorption chamber is composed of several groups of cylinders with large length diameter ratio, which can reach 12:1 (only 5:1 for traditional ones)

2. Multi chamber directional shunt, sufficient adsorption. The pressure drop is small and the pressure loss is lower than 0.03Mpa.

3. The regeneration efficiency is improved by directional diversion of regeneration gas, reducing the consumption of regeneration gas and the filling amount of adsorbent.

4. Multi group modular design of adsorption chamber makes the fuselage structure compact and reasonable, and the volume is small.

5. The adsorption chamber is made of aluminum alloy (or stainless steel, carbon steel),

The upper and lower gas collecting cavities are made of aluminum alloy, and the gas is free of secondary pollution.

6. The single volume of adsorption chamber is less than 25L, which does not belong to the special inspection scope of pressure vessel.

7. Molecular sieve is used as adsorbent to ensure the stability of dew point of compressed air at the outlet.

8. The valve is a combination valve body designed by independent patent, and the sealing element is made of imported materials.

9. The micro heat type adopts thermal insulation materials, and the overall thermal insulation has low energy consumption and high adsorbent dehydration efficiency.

10. The controller has a variety of selection modes to adapt to various operating conditions. At the same time, the controller has remote control and communication functions.

11. The installation (can be installed without foundation), maintenance and repair are very convenient, and the maintenance cost is reduced.

MD series module type heatless regeneration compressed air dryer produced by our company uses the principle of pressure swing adsorption and adopts countercurrent heatless regeneration to dry the compressed air. The structure is of double tower type. When one is adsorbed, the other is regenerated.

Cycle:

The non thermal type is 10~30 minutes, and the non thermal type is switched once every 5~15 minutes. The working cycle consists of a drying process with rising air flow and a regeneration process with falling air flow. During regeneration, a part (about 4~8%) of dried compressed air (heated by a heater) is introduced through orifice throttling, expansion and pressure reduction, and then enters the tower to desorb and blow out the moisture adsorbed in the desiccant. When the regeneration is switched to drying, the water in the compressed air is adsorbed on the desiccant again, so that the drying purpose can be achieved through circulating work.

The double towers of the modular adsorption dryer adopt multiple groups of large length diameter ratio adsorption chambers, adsorption module shunting and other ways to improve the adsorption and regeneration efficiency and miniaturize the equipment volume.

This series of products uses new and reliable advanced technologies such as pneumatic cut-off and electronic program control, and has the characteristics of automatic switching work. It can provide dry and clean compressed air for petroleum, chemical industry, medicine, food, textile, telecommunications, metallurgy, painting, cigarette, transportation, machinery manufacturing and other industries.
