Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

Referring to Figures 1-2, a polymer cylinder dehumidification wheel includes: a sealed housing 2. A first through hole and a second through hole are respectively provided on an opposite end surface of the sealed housing 2. The first through hole It is arranged opposite to the second through hole, and the first through hole and the second through hole are both provided with end plates 8 for sealing;

A rotating drum is provided between the two end plates 8. A circular hole is provided in the middle of one end plate 8. The circular hole is connected to an adsorption inlet pipe 1. A desorption outlet pipe 9 is provided in the adsorption inlet pipe 1. The desorption outlet pipe 9 is installed in the adsorption inlet pipe 1. The outlet pipe 9 extends from the surface of the adsorption inlet pipe 1; one end of the drum is provided with a driving member 5, which is used to drive the drum to rotate. The drum is surrounded by a plurality of adsorption bed units 6, and each The adsorption bed units 6 are fixedly connected through partitions 4. The adsorption bed units 6 are composed of polymer hydrogel materials, and the polymer hydrogel materials are evenly filled in a honeycomb porous form. The air to be treated is drawn from the honeycomb porous structure. By this, the area ratio of the regeneration zone and the adsorption zone in the adsorption bed unit 6 is 1:2.

During operation, the driving part 5 is turned on to cause the drum to start rotating, and the fan introduces the treatment air. After the treatment air is cooled and humidified, the temperature and humidity of the treatment air are 18°C & 95%, and enters the adsorption area of the drum through the adsorption inlet pipe 1. Dehumidification is carried out, and the temperature and humidity of the treated air become dry air of 25°C & 45%, and then discharged from the adsorption outlet 3. The regeneration fan generates hot air of 55°C & 10%, which enters the regeneration area of the drum through the desorption inlet pipe 7 for desorption. , the temperature and humidity of the processed air changes to 37°C & 43% and enters the desorption outlet pipe 9. The processed air exchanges heat with the heat exchanger, so that the air reaches the dew point temperature of 22°C, liquid water is directly condensed from the desorbed air, and the condensed water is discharge to complete the entire dehumidification process. After working for a long time, the adsorption capacity of the adsorption bed unit 6 decreases or is damaged. The sealed housing 2 can be opened to perform maintenance and replace the basic adsorption unit to continue working.

A desorption inlet pipe 7 is provided in the sealed housing 2, and the desorption inlet pipe 7 and the desorption outlet pipe 9 are located on the same side; an adsorption outlet 3 is provided on the side of the sealed housing 2 opposite to the desorption inlet pipe 7.

Furthermore, the wind in the adsorption inlet pipe 1 and the wind in the desorption inlet pipe 7 are drawn out by the same fan. The desorption outlet pipe 9 is fixedly connected with a heat exchanger 10. The heat exchanger 10 is used to improve the air flow in the desorption outlet pipe 9. The dew point temperature of the desorbed gas achieves the effect of directly generating condensed water. Regeneration air is generated by connecting the heat exchanger 10 between the desorption inlet pipe 7 and the fan.

In this example, the adsorption/desorption performance of the obtained polymer hydrogel was tested. The test results were: the adsorption capacity reached 2.32g/g under the working conditions of 25°C & 75% RH, and the polymer composite adsorbent achieved low temperature Driven desorption, dynamic desorption experiments show that the polymer hydrogel can release more than 74% of the adsorbed water at 45°C, up to 1.72g/g, and the desorption degree can reach more than 83% at 60°C, up to 1.96g/g, and Most are released in the first 170 minutes.

The adsorption performance of the polymer hydrogel can still maintain more than 90% of the initial value after 10 adsorption-desorption cycles, has good stability, and has excellent resistance to liquid decomposition.
