[0002] Silicon (Si) is one of the essential trace elements for the human body as defined by the World Health Organization. Silicon rarely exists alone in nature. It is generally widely present in rocks, gravel and water bodies in the form of complex silicates (such as aluminosilicates) or silicon dioxide. In water, the solubility of silicon dioxide itself is extremely low, but under certain conditions it can form water-soluble metasilicic acid, orthosilicic acid, etc., which are the most basic forms of silica in water.

In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0038] The various specific technical features and embodiments described in the specific implementation methods can be combined in any suitable manner unless there is any contradiction. For example, different implementation methods can be formed by combining different specific technical features / embodiments. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features / embodiments in the present invention will not be described separately.

[0039] The embodiment of the present invention provides a filter element design method, comprising the following steps: designing a metasilicic acid filter material 200 and a promoting filter material 100 that can form hydroxide ions in a water body, designing a water flow to flow through the promoting filter material 100 and the metasilicic acid filter material 200 successively or simultaneously, and the corresponding basic waterway system can refer to Figure 1 , so that the hydroxide ions formed by the filter material 100 act on the metasilicic acid filter material 200, and the metasilicic acid filter material 200 is promoted to form metasilicic acid in the water body. Metasilicic acid (H2SiO3) is generated by the hydrolysis reaction of silicate ores in water. Taking sodium silicate (Na2SiO3) as an example, However, there is a dynamic equilibrium between metasilicic acid and orthosilicic acid (H4SiO4). Orthosilicic acid has strong acidity and can exist stably in an acidic environment. Therefore, in an alkaline environment (water containing a certain concentration of hydroxide ions), it will The balance of the filter material 100 moves to the left, that is, the content of orthosilicic acid decreases and the concentration of metasilicic acid increases. In the present invention, the promoting filter material 100 is arranged upstream of the metasilicic acid filter material 200, so that the water flow can flow through the promoting filter material 100 and the metasilicic acid filter material 200 in sequence during the flow. Alternatively, the promoting filter material 100 and the metasilicic acid filter material 200 are arranged in the same filter cavity, and the water flow can flow through the promoting filter material 100 and the metasilicic acid filter material 200 at the same time during the flow. The hydroxide ions formed by the promoting filter material 100 are used to The water containing hydroxide ions acts on the metasilicic acid filter material 200, thereby promoting the dissolution rate of the silicon element in the metasilicic acid filter material 200. The concentration of metasilicic acid formed in the water is relatively high, especially in the scenario of large flow rate. By promoting the filter material 100 to the metasilicic acid filter material 200, the metasilicic acid content in the water prepared by the water purifier can meet the set requirements. When the metasilicic acid content is higher, the drinking water tastes better and has more benefits to the user's health, and the user experience is good.

[0040] Optionally, the filter material 100 is designed to be an alkaline filter material and is used to adjust the pH value of the water flow to 7.0 to 9.0. Too high alkalinity in the water body will inhibit the hydrolysis of silicate ions, thereby reducing the generation of metasilicic acid, so an appropriate alkalinity value can promote the formation of metasilicic acid, and too high alkalinity or acidity will reduce the formation of metasilicic acid.

[0041] The promoting filter material 100 may be an alkaline ore, and the mass proportion of the promoting filter material 100 refers to the mass of the promoting filter material 100 / (the mass of the promoting filter material 100+the mass of the metasilicic acid filter material 200). Table 1 shows the influence of different pH values ​​of the water (corresponding to different proportions of the promoting filter material 100) on the content of metasilicic acid in the filter element. The concentration of metasilicic acid in the flowing water and after soaking for 1 hour when the mass proportion of the promoting filter material 100 (alkaline ore) is 20%-40% (corresponding to different pH values ​​of the water) is shown in Table 1.

[0042] Table 1

[0043]

[0044] From the data in Table 1, it can be seen that in alkaline ore and metasilicic acid ore, when the mass proportion of alkaline ore is 0%, the flow water is weakly acidic water (pH value 6.2), and the metasilicic acid concentration is very low, only 0.2 mg / L. When the proportion of alkaline ore increases to 10%, the flow water is weakly alkaline water (pH value 7.1) and the metasilicic acid concentration increases. When the proportion of alkaline ore is between 20% and 40%, the metasilicic acid concentration of the flow water is above 2 mg / L. When the proportion of alkaline ore is 30%, the metasilicic acid concentration of the soaking water can reach up to 10 mg / L; when the proportion of alkaline ore is 50%, the pH of the flow water is too high (pH value 9.3), and the effect of promoting the generation of metasilicic acid begins to decrease. In specific applications, the concentration of metasilicic acid can be further increased by increasing the surface area of ​​the metasilicic acid filter material 200.

[0045] It can be seen that by adjusting the pH value of the flowing water to 7.0 to 9.0, the generation of metasilicic acid can be promoted well, and the pH value in the water body can be avoided to be too high. In specific applications, the pH value of the water body (flowing water) can be adjusted to 7.9 to 8.8 by waterway design and control. Preferably, the pH value of the water body (flowing water) is adjusted to about 8.5. In specific applications, two or more alkaline filters can be connected in parallel, wherein one alkaline filter is a strongly alkaline filter, and the other alkaline filter is a weakly alkaline filter. By controlling the mixing of the two alkaline waterways, the pH value of the water body (flowing water) can be adjusted to 8.5, and the flow water flowing through the promoting filter body can be adjusted to a stable range, which promotes the long service life of the filter body and avoids the influence of the alkalinity reduction after a single alkaline filter body is used for a long time. In specific applications, the proportion of alkaline ore can be adaptively adjusted according to the quality of the ore and other materials, so that the pH value of the flowing water is adjusted to a set range.

[0046] The present invention also provides a filter element, which can be designed by the above-mentioned design method. The filter element includes a metasilicic acid filter material 200 that can form metasilicic acid in a water body and a promoting filter material 100 that can form hydroxide ions in a water body. The promoting filter material 100 is used to form hydroxide ions in a water body. Hydroxyl ions can be used to promote the formation rate of metasilicic acid in the metasilicic acid filter material 200 in the water body. The water body containing hydroxide ions (alkaline water body) acts on the metasilicic acid filter material 200, thereby promoting the dissolution rate of silicon element in the metasilicic acid filter material 200. The concentration of metasilicic acid formed in the water body is relatively high. Especially in the scenario of large flow, through the promoting effect of the promoting filter material 100 on the metasilicic acid filter material 200, the metasilicic acid content in the water body can meet the set requirements.

[0047] In a specific application, the promoting filter material 100 is an alkaline filter material. When water flows through, the pH value of the water flowing through the promoting filter material 100 can be between 7.1 and 9.0. The promoting filter material 100 can include at least one of brucite, periclase, calcite, and dolomite; the metasilicic acid filter material 200 includes at least one of diopside, serpentine, and medical stone.

[0048] Specifically, the material of the filter material 100 and the material of the metasilicic acid filter material 200 are mixed and solidified, that is, the filter element is an integrated structure, which is convenient for assembly. In specific applications, the filter element can be in the shape of an integral carbon rod. Alternatively, the filter material 100 and the metasilicic acid filter material 200 are connected as a whole along a set direction. For example, the filter material 100 and the metasilicic acid filter material 200 are arranged up and down along the axial direction of the filter cartridge, or the filter material 100 and the metasilicic acid filter material 200 can also be arranged inside and outside along the radial direction of the filter cartridge. Specifically, the filter material 100 is relatively arranged upstream of the metasilicic acid filter material 200, so that the flowing water (water body) flowing through the metasilicic acid filter material 200 is alkaline.

[0049] Specifically, the filter material 100 and the metasilicic acid filter material 200 can also be separately formed and connected by assembly. Specifically, the filter material 100 and the metasilicic acid filter material 200 can be fixedly connected along a set direction by bonding, end cap connection, central tube connection, etc. The carriers of the filter material 100 and the metasilicic acid filter material 200 can be the same or different. The filter material 100 and the metasilicic acid filter material 200 are separately arranged along a set direction, that is, the filter material 100 and the metasilicic acid filter material 200 can also be separately arranged in different filter cartridges, and the filter material 100 and the metasilicic acid filter material 200 are connected in series in the waterway.

[0050] Specifically, the filter element has a matrix, which is made of carbon material in the shape of a carbon rod, and the material of the promoting filter material 100 and the material of the metasilicic acid filter material 200 are mixed with the carbon material and sintered to form a monolithic structure of the filter element. The carbon material can be carbon powder or rubber powder. After the filter element is formed, it can be in the shape of a columnar carbon rod, and water can flow through the filter element along the axial direction or radial direction of the columnar filter element. After the filter element is formed, it can also be in the shape of a cylindrical carbon rod, and water can flow through it along its radial direction.

[0051] Alternatively, the filter element has an integral substrate, the substrate is a carbon rod filter material, a carbon fiber filter material, a carbon particle filter material or a ceramic filter material, and the material of the filter material 100 and the material of the metasilicic acid filter material 200 can be attached to the substrate; for example, when the substrate is a carbon rod filter material, the filter material 100 and the metasilicic acid filter material 200 are respectively attached or dispersedly arranged on the upper part and the lower part of the carbon rod filter material (refer to Figure 3 Alternatively, the filter material 100 and the metasilicic acid filter material 200 may also be arranged radially inwardly or outwardly inwardly along the carbon rod filter material (see Figure 4When the substrate is a carbon fiber filter material, the promoting filter material 100 and the metasilicic acid filter material 200 are respectively arranged on the same surface of the carbon fiber filter material, and the promoting filter material 100 and the metasilicic acid filter material 200 can be arranged in layers along the length direction or width direction of the carbon fiber filter material. Of course, the promoting filter material 100 and the metasilicic acid filter material 200 can also be arranged on the front and back of the carbon fiber filter material respectively. The carbon fiber filter material can be wound into a columnar or cylindrical shape.

[0053] Optionally, the mass proportion of the promoting filter material 100 and the metasilicic acid filter material 200 is 20% to 40%, so as to adjust the pH value of the flowing water to a set range. In specific applications, a pH sensor can be provided in the waterway, and the pH sensor is downstream of the promoting filter material 100 and upstream of the metasilicic acid filter material 200. Through flow control, the pH value of the water discharged from the promoting filter material 100 can be adjusted to be within a set range, which is conducive to promoting the metasilicic acid filter material 200 to form metasilicic acid in the water body.
