Problems solved by technology

[0009] The main advantages of the fixed rotary dehumidification include: the only moving part is the rotary motor 6, the wheel core is made of silica gel and molecular sieve, and the dew point of the air after treatment can reach below -60°C; the biggest disadvantage is: if required to pass through The dew point temperature of the air treated by the runner is about 0°C, and the regeneration temperature when the runner is working needs to be at 110-180°C
The biggest disadvantage of liquid spray dehumidification is: the air is very likely to carry the absorption liquid during the process of air dehumidification and absorption liquid regeneration, causing various adverse effects
Although the lithium chloride produced by these methods can work under regeneration conditions at about 100°C, it has a fatal flaw: when the runner is stored under high humidity conditions, after the lithium chloride on the runner absorbs moisture in the air , the amount of liquid lithium chloride solution will increase, and the ability of the runner substrate to absorb water is limited, and eventually the water will flow away from the runner, resulting in the loss of lithium chloride, and even the failure of the runner

Abstract

The invention discloses a manufacturing method of the wheel center of a dehumidification rotating wheel. The method comprises the following steps of: firstly, mixing powdered materials capable of adsorbing liquid water with binder, suspending agent solid and water to form a sizing agent; secondly, coating the sizing agent obtained on a carrier; thirdly, thermally pressing the carrier coated with the sizing agent to a corrugated shape; rolling or folding the obtained corrugated carrier into a wheel center and baking; and finally placing the obtained wheel center into a LiCL solution for soaking to obtain the final wheel center. The wheel center obtained by adopting the method has stronger moisture absorption performance, and practice proves that the air processing effect is very obvious by adopting the wheel center of the dehumidification rotating wheel. The moisture content and the dew-point temperature of output air of damp air processed by the wheel center are both very low, therefore, the invention can be widely applied to the field of air dehumidification and replace the traditional fixed rotating wheel dehumidification and liquid spraying dehumidification.

Description

technical field [0001] The invention relates to a method for manufacturing a wheel core of a dehumidification wheel. Background technique [0002] In the field of air dehumidification, commonly used drying dehumidification methods (desiccant airdryer) mainly include fixed wheel dehumidification and liquid spray dehumidification. At present, the mainstream companies producing this product in the world are Munters of Sweden and Kathabar of the United States. [0003] Fixed wheel dehumidification and liquid spray dehumidification each have their unique advantages, but also have their inherent defects. [0004] Among them, the fixed wheel dehumidification structure is simple, combined with figure 1 , which works like this: [0005] On both sides of the rotor, the entire surface is divided into two sectors by highly airtight partitions or similar structures: treatment sector 1 and regeneration sector 2. [0006] The humid air that needs to be dehumidified (called treatment air...
