Working Principle Of Desiccant Dehumidifiers

Dehumidification process: Humid air is drawn through the honeycomb matrix of the rotor by process fan,moisture in humid air is absorbed by the desiccant in process area and become dry
Reactivation process: The desiccant desorbs the moisture into the hot air from reverse direction which then is exhausted outside by a reactivation fan.
The desiccant rotor is divided into a process area and a reactivation area. When humid air is drawn through the honeycomb matrix of the rotor by process fan,moisture is removed by the silica gel or molecular sieve desiccant and dried air is supplied to a room or any place that it is needed.
Simultaneously, the 'reactivation air', drawn from from the reverse direction, is heated and passed through the honeycomb matrix in the reactivation area of the rotor. The desiccant desorbs the moisture into the hot air which then is exhausted outside by a reactivation fan. A gear motor drives the desiccant rotor to rotate slowly to repeatedly absorbs moisture and realize continuous dehumidification.

To maximize engery efficiency, outside air is usually cooled down to 13Celcius/95%RH bY water cooled coil or DX coil and then further dehumidified by the revolving desiccant wheel and slightly heated up.

Principle Of VOC Treatment Equipment

What is VOC concentrator?
VOC concentrator can effectively purify and concentrate VOCs laden air stream exhausted from industrial factories. By being combined with incinerator or solvent recovery equipment, both initial and operating costs of the entire VOC abatement system can be drastically reduced.
 VOC concentration rotor is made of honeycomb inorganic paper as a substrate, in which the High-Silica zeolite (Molecular Sieve) is impregnated. The rotor is divided into 3 zones such as process, desorption and cooling zones by the casing structure and heat resistance air sealing. The rotor is constantly rotated at the optimum rotation speed by a geared motor.

Principal of VOC concentrator:

When VOC laden exhaust gas passes through the process zone of the rotor which is continuously rotated, the incombustible zeolite in the rotor absorbs VOCs and purified gas is exhausted to the ambient; VOC absorbed part of the rotor is then rotated to the desorption zone, where the absorbed VOCs can be desorbed with small amount of high temperature desorption air and be concentrated to the high concentration level (1 to 10 times). Then, the high concentrated VOC gas is transferred to appropriate post treatment systems such as incinerators or recovery systems;the desorbed part of the rotor is further rotated to the cooling zone, where the zone is cooled by the cooling gas. A part of VOC laden exhaust gas from the factory passes through the cooling zone and is transferred to a heat exchanger or a heater to be heated and utilized as desorption air.
