1.Working principle
Adsorption principle: The use of adsorbents (such as activated alumina, silica gel, molecular sieve, etc.) on the adsorption of water, when the humid compressed air through the adsorbent adsorption tower, water is adsorbent, so that the outflow of air becomes dry.

Regeneration principle: After the adsorbent absorbs water to saturation, it needs to be regenerated to restore its adsorption capacity. There are two common forms of regeneration. One is heating regeneration, by heating the adsorbent, so that the adsorbed water evaporates out and is discharged with the air flow; The other is non-thermal regeneration, using the low-temperature air flow formed after the partial drying compressed air depressurization expansion, to purge the adsorbent and take away water.

2.Structural composition
Adsorption tower: is the core part of the dryer, the interior is filled with adsorbent, usually there are two adsorption towers, one is used for adsorption drying, the other is used for regeneration, by switching valves to achieve alternate work.

Control system: used to control the switching of the adsorption tower, regeneration time and other parameters to ensure the stable operation of the dryer. There are two common control systems: time control and dew point control. Time control can switch and regenerate the adsorption tower according to the set time period. The dew point control automatically adjusts the regeneration cycle according to the dew point temperature of the compressed air, which is more energy efficient and accurate.

Valve: including air intake valve, air outlet valve, regeneration valve, etc., used to control the flow of compressed air and on and off, to achieve the adsorption and regeneration process switch.

Muffler: Installed in the regenerative exhaust port, used to reduce the noise of the exhaust gas during the regeneration process.

1. Plastic particle transport: In the production and processing of plastic particles, compressed air is usually used to transport plastic particles. The dry compressed air can prevent the plastic particles from being damp and caking, ensuring the fluidity of the particles and the smoothness of transportation. The adsorption dryer can remove the moisture in the compressed air to avoid the subsequent processing performance of plastic particles due to moisture during transportation, such as the fluidity of injection molding and the mechanical properties of products.

2. Plastic mold cooling: In the cooling process of plastic molds, compressed air is sometimes used to assist cooling. Dry compressed air can avoid the formation of condensed water on the mold surface, prevent mold rust and plastic products surface water stains, deformation and other problems. By using adsorption dryers to provide dry compressed air, it is possible to improve the service life of molds and the molding quality of plastic products.

3. Purging of electrical equipment: During the maintenance and overhaul of electrical equipment, compressed air needs to be used to purge the interior of electrical equipment to remove dust and debris. Dry compressed air can prevent moisture inside the device, avoid the deterioration of insulation performance and short-circuit faults. The adsorption dryer provides dry and clean compressed air for electrical equipment purging, ensuring the safe operation of power equipment.

4. Pneumatic control system: Some pneumatic control systems in power plants, such as the speed control system of steam turbines, the control of pneumatic valves, etc., rely on dry compressed air. Moisture will affect the sensitivity and reliability of the pneumatic control system, resulting in inaccurate control signals, slow valve action and other problems. The compressed air adsorption dryer can ensure the air source drying of the pneumatic control system, improve the stability and control accuracy of the system, and ensure the normal progress of the power production process.

5. Parts painting: In the painting process of automobile body and parts, the dryness of compressed air is very high. If the compressed air contains moisture, it will cause pinholes and bubbles in the paint coating, affecting the appearance quality and anti-corrosion performance of the car. The adsorption dryer can ensure the supply of dry and clean compressed air, ensure the painting effect, make the surface of the car smooth, uniform color, and improve the overall quality of the car.

6. Use of pneumatic tools: a large number of pneumatic tools such as pneumatic wrenches and pneumatic screwdrivers are used on automobile production lines, which require dry compressed air to ensure their normal operation and service life. Moisture will cause rust and wear of the internal parts of the pneumatic tool, reducing the accuracy and efficiency of the tool. Compressed air adsorption dryer can effectively remove water, so that pneumatic tools to maintain good working condition, improve production efficiency and assembly quality.

1. What is the reason for the pressure reduction in the operation of the adsorption dryer?
The pipe may be blocked, causing the intake and outlet pressure to drop. Check and clean the pipe or replace the pipe. It may also be compressed air leakage, affecting pressure and efficiency, to check the system connection part, repair or replace damaged seals and connection parts.

2. How often does the adsorbent need to be replaced?
Depends on the quality of adsorbent, intake water content, use environment and other factors. It is found that the adsorption performance of the adsorbent is significantly reduced, such as the dew point of the compressed air after drying is not up to standard, or the adsorbent is polluted, broken, etc., it needs to be replaced. Under normal circumstances, high-quality adsorbents may be used for 2 to 5 years, but may need to be replaced more frequently under harsh conditions.

3. What is the pressure dew point? How does it affect dryer performance?
The pressure dew point is the temperature at which compressed air cools to saturation at a certain pressure, at which point water vapor in the air begins to condense into water droplets. The lower the pressure dew point, the higher the degree of drying of compressed air, the better the performance of the dryer, and the better to meet the industrial applications with high air drying requirements.

4. What should we do if the treatment gas volume of the dryer does not reach the design value?
Check whether there is blockage in the intake pipe and whether the valve is fully open to ensure smooth intake; Check whether the switching of the adsorption tower is normal. If the switching failure occurs, the processing gas volume may decrease. Check whether the adsorbent is invalid or polluted, if there is a problem, replace or regenerate the adsorbent in time; It is also necessary to check whether the system has leaks, if there are leaks, it should be repaired in time.
