Blow hot zero gas consumption adsorption dryer - Windwick fan

I have sorted out the main functions, selection points, and precautions of using high-pressure blowers in drying machines and zero gas consumption adsorption drying machines with wind vic cast aluminum high-pressure blowers, and provided recommended tips for you.

1、 The main function of high-pressure blower

In the hot air zero gas consumption adsorption dryer, the high-pressure blower is the core power source of its regeneration system, playing the role of the "hot air heart". Its main functions are as follows:

1. Provide regeneration airflow: Generate a continuous, high-pressure airflow to blow and remove moisture from desiccants (such as alumina and molecular sieves) that have already been adsorbed, achieving the regeneration of desiccants.

2. Blast heating: The high-pressure air flow output from it is heated by a heater (usually electric heating or steam heating) and transformed into high-temperature and low humidity regeneration gas. Hot air can significantly reduce the adsorption force of desiccants on moisture, greatly improving regeneration efficiency and depth.

3. Establish pressure and flow rate: Ensure that the regeneration gas has sufficient pressure to penetrate the desiccant bed and maintain flow rate, so that moisture can effectively desorb and be carried out of the drying tower, while avoiding uneven airflow distribution or the formation of "channeling".

4. Achieving "zero gas consumption": Unlike traditional compression heat or vacuum regeneration, blast heat regeneration uses ambient air as the gas source, which is pressurized and heated by a blower before being used for regeneration. The regenerated humid air is cooled and separated before being discharged, and the entire process does not consume finished compressed air, hence it is called "zero gas consumption".

2、 Key points for selection (air volume, pressure, power)

The selection should be based on the specific design parameters of the dryer and matched with the desiccant filling amount, regeneration cycle, heating power, etc.

Parameter Key Points Explanation Estimation Reference/Range

1. The most critical parameter of air volume (Q). Refers to the volumetric flow rate output by the blower under standard conditions. The air volume determines the "flushing" ability of the regeneration gas, directly affecting the regeneration time and effect. Usually 5% -15% of the rated processing capacity of the dryer. For example, processing a 100 m ³/min dryer requires a regeneration air volume of approximately 5-15 m ³/min. The specific needs to be determined based on the type of desiccant, regeneration temperature, and cycle calculation.

2. Key parameters of pressure (P). The total system pressure that the blower needs to overcome includes heater resistance, desiccant bed resistance, pipeline valve resistance, and cooler resistance. Insufficient pressure can cause the regeneration airflow to be unable to effectively penetrate the bed layer. The range is usually between 15-50 kPa (approximately 0.15-0.5 bar, or 2.2-7.3 PSI). Among them, the resistance of the desiccant bed is the main part, which will slightly increase with the use time (dust accumulation). It is necessary to confirm the system design resistance curve with the dryer manufacturer.

3. Power (kW) derived parameters. After determining the required air volume and pressure, calculate or have the supplier determine the motor power based on the efficiency curve of the blower. Power=(air volume x pressure)/(efficiency x safety factor). For the above wind pressure range, the power ranges from several kilowatts to tens of kilowatts. For example, a blower with an air volume of 10 m ³/min and a pressure of 35 kPa may have a motor power of around 7.5-11 kW.
