Abstract

The invention discloses a dehumidification rotating wheel and a preparation method thereof. Specifically, the dehumidification rotating wheel comprises a honeycomb-shaped rotating wheel body, wherein the honeycomb-shaped rotating wheel body comprises inorganic fiber paper and a silica gel layer and a molecular sieve layer which are sequentially compounded on the outer layer of the inorganic fiber paper; the silica gel layer is prepared by dipping the honeycomb-shaped rotating wheel body in a sodium silicate solution to form a gel layer and then enabling the gel layer to react with metal salt. The preparation method of the dehumidification rotating wheel comprises the following steps: (1) preparing the honeycomb-shaped rotating wheel body; (2) preparing the gel layer by using the sodium silicate; (3) dipping the gel layer into a metal salt solution to prepare the silica gel layer; (4) preparing the molecular sieve layer, thus obtaining the rotary dehumidification wheel. The dehumidification rotating wheel provided by the invention is light in weight, high in strength and durable in use; the molecular sieve layer and the silica gel layer are sequentially formed on the surface of the inorganic fiber paper in situ by adopting a dipping method, the technological operation is simple, the adsorption between the molecular sieve layer and the silica gel layer is firm, and higher stability is obtained.

Description

Technical field [0001] The invention relates to the field of dehumidification equipment, in particular to a dehumidification runner and a preparation method thereof. Background technique [0002] In the wet weather represented by the rainy season, it is usually necessary to dehumidify the room to reduce discomfort. In addition to the traditional use of desiccants such as calcium chloride for adsorption, the method of dehumidification can also be dehumidified by a dehumidifier. The effect of household refrigeration dehumidifier is not ideal, and it is large in size and consumes a lot of power. [0003] Household rotary dehumidifiers such as figure 1 As shown, it includes a heat exchanger 2, a runner body 3, a heater 4, a dehumidification fan 5, and a regeneration fan 6. The moisture 1 is converted into droplets 7 under the operation of the dehumidifier. Although the dehumidification effect is relatively good, the size of the runner is also limited by the product volume. In order ...
