Heatless Core Dryer

Introduction to the heatless module series adsorption dryer:
1. The adsorption chamber is composed of multiple groups of cylinders with a large aspect ratio, which can reach 12:1 (the traditional one is only 5:1)
2. The multi-cavity directional diversion ensures sufficient adsorption. The pressure drop is small, and the pressure loss is less than 0.03Mpa.
3. The regeneration gas is directionally diverted, the regeneration efficiency is improved, and the regeneration gas consumption and adsorbent filling amount are reduced.
4. The adsorption chamber has multiple groups of modular design, the fuselage structure becomes 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 chambers are made of aluminum alloy, and the gas has no secondary pollution.
6. The single volume of the adsorption chamber is less than 25L, which does not belong to the special inspection category of pressure vessels.
7. The adsorbent uses a molecular sieve to ensure the stability of the outlet's compressed air dew point.
8. The valve adopts a combined valve body with an independent patent design, and the seal is made of imported materials.
9. The micro-heat type uses insulation materials, integral insulation, low energy consumption, and high adsorbent dehydration efficiency.
10. The controller has a variety of selection modes to meet various working conditions. At the same time, the controller has remote control and communication functions.
11. Installation (can be installed without foundation), maintenance, and maintenance are very convenient, and maintenance costs are reduced.
The MD series modular 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 a double tower type, one adsorbs and the other regenerates.
Cycle period:
The heatless type is 10 to 30 minutes, and the heatless type switches every 5 to 15 minutes. The working cycle consists of a drying process with rising airflow and a regeneration process with falling airflow. During regeneration, a part (about 4 to 8%) of the dried compressed air (the micro-heat type is heated by a heater) is drawn out through the orifice plate throttling expansion and pressure reduction and enters the tower to desorb and blow out the moisture adsorbed in the desiccant. When the regeneration is switched to drying, the moisture in the compressed air is adsorbed on the desiccant again, and the cycle works in this way to achieve the purpose of drying.
The double towers of modular adsorption dryers all use multiple groups of adsorption chambers with large aspect ratios and adsorption module splitting, which improves the adsorption and regeneration efficiency and makes the equipment smaller.
This series of products uses novel and reliable advanced technologies such as pneumatic cut-off and electronic program control and has the characteristics of automatic switching. It can provide dry and clean compressed air sources for industries such as petroleum, chemical, pharmaceutical, food, textile, telecommunications, metallurgy, painting, cigarettes, transportation, and machinery manufacturing.
