Compressed air dryer operating principle Compressed air dryer features

When choosing a compressed air dryer, we first need to consider the pressure dew point temperature required by the customer to decide which type of compressed air dryer to use. When the dew point temperature of the compressed air requires a temperature above 0°C, a freeze dryer is often used. When the temperature is below 0°C, an adsorption dryer should be used. Next Xiaobian introduced the working principle of the compressed air dryer and the characteristics of the compressed air dryer.

Compressed air dryer works

1. The working principle of freezing dryer

The refrigerated compressed air dryer reduces the temperature by cooling, so that the water vapor in the compressed air condenses into droplets, thereby achieving the purpose of reducing the moisture content. The condensed droplets exit the dryer through an automatic drainage system.

2, micro heat regeneration adsorption dryer works

The micro-thermal regeneration adsorption dryer adopts the alternate operation of the twin towers. The compressed air enters the tower of the dryer A through the valve 1A (1B closed), and the gas is dehydrated and dried under the unique adsorption effect of the adsorbent. The finished gas passes through the valve 5A (5B). Closed) to the point of use, while about 5% of the dry gas source is heated by the heater and then passed through the valve 4B (4A closed) into the tower B. After heating for a certain period of time, the adsorbent is regenerated and stopped. After heating, it enters the cold blowing stage to cool down the adsorbent bed of the desiccator tower B (to prepare for the next cycle), and then discharges it into the atmosphere through the silencer, closes the valve 2B before switching in the second half of the cycle, and opens the valve 1B to make the two tower bodies. After the pressure is equalized, the switching is completed (guaranteing the stable use of the gas pressure and avoiding the impact shock of the dryer). At the same time, the work is started in the second half of the cycle (operation of the dryer B tower and regeneration of the dryer A tower), and the flow is similar to the first half cycle.

3, combination dryer working principle

The combination dryer is reasonable to combine the freeze dryer and the adsorption dryer together. The air treated by the dryer does not pass through the pre-cooler, and directly enters the adsorption dryer after draining from the separator of the dryer. At this time, the temperature of the drying air is about 2°C-5°C, and the dew point is about 5°C. At this time, the adsorption dryer continues to perform deep adsorption, and the lower the temperature of the adsorption dryer is, the better the dew point is. Therefore, the combined dryer can achieve a more stable pressure dew point. Before entering the adsorption dryer, a part of the water has been removed by the cold dryer, which reduces the workload of the adsorption dryer. Therefore, the adsorption dryer can be switched for a longer time, thereby reducing the air consumption.

2, adsorption dryer

(1) Strictly comply with ISO9001, GB standards, QS, and pressure vessel inspection specifications to ensure the safe and reliable operation of products. The demanding perfect design leads to long-term, high-efficiency and stable operation of the product; the use of an excellent heating element increases the temperature of the regeneration gas, while the regeneration air volume requires only 6% of the treatment volume.

(2) E-CTRL series microcomputer control panel is a real-time operating system based on advanced microprocessors. It performs comprehensive control and monitoring through a simple and clear user interface. The user can identify any condition of the dryer during operation to ensure that it is used in sensitive applications. At the same time E-CTRL is also equipped with remote control port, joint control port to meet the special needs of users.

(3) Pneumatic valves and control valves adopt international high-quality brands, as well as specially designed refueling systems and oil recovery systems, which are in line with the environmental protection philosophy advocated by Sievers while improving the service life and stability.

(4) The valve switching is controlled by a microcomputer program controller, and the performance is stable. This ensures that there is no air-breaking phenomenon when the adsorption tower is switched, and the impact of the gas flow on the adsorbent is avoided, so that the adsorbent has a longer life.

(5) The product can accept a variety of special customization (processing capacity greater than 110Nm/min, special materials, -70 °C dew point temperature, high pressure above 0.98MPa, special control methods, etc.).
