Absorption Air Dryers
- Absorption Air Dryers
Absorption Air Dryer
These types of dryers have two towers, and in some cases 3 towers or pressure vessels.
Both of these are filled with absorbent materials such as activated alumina, silica gel, molecular mesh or other adsorbent materials.
In these drives, compressed air, by passing through the moisture absorbing materials contained in these tanks, has largely lost its moisture.
After absorbing water by these materials, Dyer uses the compressed air produced in the system to immerse the absorbent material in the substrate and repel moisture.
The dew point pressure absorber reduces compressed air to prevent water distillation.
In these dryers, the dew point is about -40 ?C.
In some industries, the dew point needed for work is -70 ?C, which means that due to lower temperatures, the amount of water distillation is also lower.
Absorbent dryers use a variety of methods to filter compressed air.
Types of absorbent dryers:
Absorbent dry heaters
Blow-dry heat exchangers
In these devices, some of the compressed air is driven into one of the resting towers. This dry air passes through saturated adsorbent materials and releases moisture through an exhaust to air. This The cycle is called the absorbing material recovery cycle
Thermal absorption dryers:
In this type of dryer, the dry air first passes through a high performance external heater, then returns to the resting tower and recovers the absorbent material using hot air. As this method Hot air is used to dry the saturated absorbent material, half of the dry compressed air is needed in this regard compared to non-heated absorption dryers.
Blower Heat Exchanger:
In this technology, the machine is equipped with a centrifugal blower. The blower is designed to suck the air and transfer it from a sweatshield and then pass it through the tower at rest. Thus, the moisture content of The adsorbent material is driven. In other words, the centrifuge sweeps the air into the heater and then drains it into the resting tower where the absorbent material is saturated with moisture and blurs the absorbent material. Comparing this type of dryer with Two other types should be added that they are more expensive than the two dryers in terms of price, but instead, maintenance costs and operating costs are lower due to the lack of use or very little use of compressed air for the recovery of adsorbent materials.
The compressor is available as a supplier of absorbent dryers with a dew point of -70 ° C and environmental conditions with a relative humidity of 100% and an incoming temperature of +35 ° C and other facilities such as dew point change, steam regeneration, limiting keys, Pressure control devices, measuring instruments, adaptability for outdoor operation, and the possibility of outlet for periodic services and maintenance operations, are for use in various industries. The adsorption circuits provided by Behsan Company, the company's construction Valid European and American Certificates are provided with valid warranties and warranties.
