Description
Technical Field
The invention relates to a water mineralization material, in particular to a mineral filter material applied to a water purifier, and also relates to a filter element manufactured by the mineral filter material and a water mineralization method.
Background
With the continuous improvement of the living quality of people, the cognition on the drinking water is continuous and deep. The beverage is changed from convenient drinking in the morning to safe drinking. Correspondingly, related water purification technologies are continuously updated, and traditional municipal tap water is used as a water purifier taking reverse osmosis technology as a core.
However, the reverse osmosis solves the problem of drinking water safety, and simultaneously reduces the health attribute of water produced by the water purifier due to the characteristic of removing beneficial minerals in water. To remedy this drawback, mineralized filter elements have been developed. It increases the mineral content of water by releasing minerals into the water. The related documents refer to the disclosure of Chinese patent application with application number 201510496466.X of filter element material proportioning and combination mode of water purifier (application publication number CN 105481134A); reference may also be made to the chinese invention patent application publication "five-membered mineral matter purification energy material" (application publication No. CN106986435A) with application No. 201610170022.1.
When raw water enters the mineralization filter element, trace elements contained in the mineralization materials are released into the water, so that the aim of increasing the content of mineral substances in the water is fulfilled. There are several problems, however: first, the rate of mineral dissolution is slow. During the time that the influent water is in contact with the mineralized filter elements, the mineral content in the water cannot be effectively increased. There are patents that increase the rate of mineral precipitation by lowering the pH of the influent water through the use of carbon dioxide. However, the pH value of the acidic water is limited, the defect of slow dissolution rate cannot be completely solved by single use, and the release of mineral substances is promoted by blending active oxygen molecules into the filter element. However, the active oxygen molecules have extremely strong oxidizability, and the whole process is an oxidation process, so that potential safety hazards exist. The related documents refer to the Chinese patent application publication No. 201880048943.8, entitled "method and household utensil for producing mineral water from tap water" (application publication No. CN 111108068A).
Secondly, the dissolution rate of minerals is not controllable: in CN111108068A, the mineralized material is processed into micron-sized powder, so as to achieve the purpose of rapid dissolution. This process, although accelerating dissolution, also carries the risk of uncontrollable dissolution rates.
