Description

TECHNICAL FIELD

[0001] The present application relates to a water treatment device, in particular to a hydrogen water production device. BACKGROUND

[0002] Hydrogen-rich water, also known as Hydrogen Water, is a kind of drinking water obtained by dissolving hydrogen into water. Hydrogen itself is a natural antioxidant, and water with hydrogen has strong reducing function.

[0003] However, as a non-polar molecule, hydrogen is not easy to dissolve in water, and the solubility of hydrogen in water is very low and difficult to preserve. How to dissolve as much hydrogen as possible in water and preserve it for a long time becomes an important indicator to measure the quality of hydrogen-rich water. In order to solve the technical problem of low mixing efficiency of gas and liquid, the industry has proposed various hydrogen-rich water preparation systems. For example, Chinese invention patent CN104016471B records a method for preparing long-acting hydrogen-rich water at low cost, which specifically proposes that water runs from top to bottom, hydrogen runs from bottom to top, and gas and liquid two-phase countercurrent mixing, sufficient contact and absorption balance effect are formed. However, the mixing degree of gas and liquid in the above hydrogen-rich water preparation system is low, and the contact degree of gas and liquid limits the solubility of gas in liquid. In order to further improve the gas-liquid mixing degree and thus improve the solubility of hydrogen in hydrogen-rich water, the present application proposes a high-concentration hydrogen-rich water preparation system.

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings of the present application. Obviously, the described embodiments are only some non-restrictive embodiments of the present application, and are only used to explain the present application but not to limit the present application.

The hydrogen-rich water collecting unit 60 is provided with a hydrogen-rich water collecting port 66 at the bottom thereof, and the hydrogen-rich water collecting port 66 is provided with a switch valve 68.

[0029] As shown in Figure 1 and Figure 2 , the jetting element 100 vertically extends from the top of the hydrogen-rich water collecting unit 60 to the inside of the hydrogen-rich water collecting unit 60, and comprises a columnar tube body 110 fixedly connected to the top wall of the hydrogen-rich water collecting unit 60, and a horn-shaped tube body 120 integrally formed with the columnar tube body 110. The gas-liquid mixing unit 10 comprises at least one liquid inlet 15 connected to the water purification unit 20, and at least one gas inlet 16 connected to the hydrogen gas pressurizing device 30. After being purified by the water purification unit 20, the water source enters the gas-liquid mixing unit 10 through the liquid inlet 15. The gas, such as hydrogen gas, is produced by the hydrogen production unit 50 and stored in the hydrogen storage unit 40. The hydrogen gas from the hydrogen storage unit 40 is pressurized by the hydrogen gas pressurizing unit 30 and then enters the gas-liquid mixing unit 10 through the gas inlet 16.

[0030] As shown in Figure 2 , the jetting element 100 has a fluid inlet end A (front end) and a fluid outlet end B (rear end), and the liquid and the gas are mixed at the fluid outlet end B of the jetting element 100. A cover 200 is combined with the outlet end B of the jetting element 100.

[0031] The jetting element 100 has the columnar tube body 110 at the front section and the horn-shaped tube body 120 at the rear section, and is provided with a plurality of independent flow guide cavities inside. Each of the independent flow guide cavities comprises an independent fluid inlet and a fluid outlet, and the fluid outlets of the flow guide cavities are located at the end face of the horn-shaped tube body 120 of the jetting element 100.

[0032] A tubular fluid cavity 130 is arranged in the center of the jet element 100, a first annular fluid cavity 140 is arranged inside the jet element 100 and surrounds the outside of the tubular fluid cavity 130, the first annular fluid cavity 140 includes a cylindrical portion at the front section and a horn-shaped portion at the rear section; a second annular fluid cavity 150 is arranged outside the first annular fluid cavity 140, the second annular fluid cavity 150 only includes a horn-shaped portion at the rear section; a third annular fluid cavity 160 is arranged outside the cylindrical portion at the front section of the first annular fluid cavity 140 and the second annular fluid cavity 150, the third annular fluid cavity 160 includes a cylindrical portion at the front section and a horn-shaped portion at the rear section. The cross sections of the first annular fluid cavity 140, the second annular fluid cavity 150 and the third annular fluid cavity 160 are all annular.

[0033] In this way, a plurality of annular fluid cavities with annular cross sections are formed inside the jet element 100, and the cross section of the Nth annular fluid cavity is surrounded by the (N+1)th annular fluid cavity. The tubular fluid cavity and the plurality of annular fluid cavities are respectively in communication with the corresponding fluid inlets and fluid outlets at both ends. The fluid outlets of the tubular fluid cavity 130 and the annular fluid cavities 140, 150 and 160 are all located on the end face of the fluid outlet end B of the jet element 100.

[0034] Specifically, the fluid outlets of each flow guide cavity are arranged in a layer-by-layer manner from the center to the periphery of the fluid outlet end face B of the jet element 100, and the fluid outlets in the center are surrounded by the fluid outlets in the periphery, and the fluid outlets of each flow guide cavity are arranged alternately as gas outlets and liquid outlets on the cross section of the fluid outlet end B of the jet element.

[0035] The fluid inlet end of the tubular fluid cavity 130 can be arranged on the front end face of the columnar pipe body 110 or on the tubular outer wall of the columnar pipe body 110; the fluid inlet ends of the annular fluid cavities 140, 150 and 160 can be arranged on the front end face of the columnar pipe body 110 or on multiple positions of the outer wall of the jet element 100, such as the front end face of the columnar pipe body 110, the side wall of the columnar pipe body 110, and the side wall of the horn-shaped pipe body 120. These fluid inlets are respectively in communication with the liquid inlet 15 or the gas inlet 16 through pipelines according to the requirements.

[0036] As a non-limiting embodiment, as Figure 2As shown, the fluid inlet 141 of the first annular fluid chamber 140 is located on the front end surface of the cylindrical tube body 110, the fluid inlet 131 of the tubular fluid chamber 130 and the fluid inlet 161 of the third annular fluid chamber 160 are both located on the side wall of the cylindrical tube body 110, and the fluid inlet 151 of the second annular fluid chamber 150 is located on the side wall of the horn-shaped tube body 120. Meanwhile, a turbofan pressurizer 170 is arranged inside the fluid inlet of the first annular fluid chamber 140, so as to ensure that the jet fluid entering the chamber 140 has proper fluid pressure.

[0037] Specifically, the second annular fluid chamber 150 is located only inside the horn-shaped tube body 120, that is, the second annular fluid chamber 150 only includes a horn-shaped space gradually expanding towards the fluid outlet end B, and the fluid inlet 151 of the second annular fluid chamber 150 is arranged along the tangential direction of the outer ring of the annular cross section of the second annular fluid chamber 150, so that the fluid medium such as hydrogen gas entering the second annular fluid chamber 150 presents a spiral flow. As a non-limiting embodiment, at least three fluid inlets 151 can be arranged at equal intervals on the side wall of the second annular fluid chamber 150.

[0038] As a non-limiting embodiment, the third annular fluid chamber 160 longitudinally penetrates the entire jet element 100. The fluid inlet 161 of the third annular fluid chamber 160 is arranged along the tangential direction of the outer ring of the annular cross section of the third annular fluid chamber 160, so that the fluid medium such as water entering the third annular fluid chamber 160 presents a spiral flow. When the gas and the liquid contact at the fluid outlet end B, the above-mentioned gas and liquid with spiral motion both have higher rotational flow characteristics, so that the gas-liquid mixing is more violent and uniform, and the hydrogen bubbles can be broken into smaller bubbles, thereby improving the hydrogen dissolution rate.

[0039] As a non-limiting embodiment, as shown in the drawings, Figure 3 As shown, the first annular fluid chamber 140 is provided with a tapered narrowing portion 142 on the inner wall of the horn-shaped portion in the rear section, which reduces the inner diameter of the chamber. The tapered narrowing portion 142 reduces the liquid cross section when the fluid (such as water) flows through it. Preferably, the third annular fluid chamber 160 is also provided with a tapered narrowing portion 162 which reduces the inner diameter of the chamber, and preferably, the tapered narrowing portion 162 is located at the connection between the cylindrical portion in the front section and the horn-shaped portion in the rear section. The tapered narrowing portion 162 reduces the liquid cross section when the fluid (such as water) flows through it. The existence of the above-mentioned tapered narrowing portions 142 and 162 further improves the liquid flow rate and pressure, and can effectively improve the atomization effect of the liquid.

[0040] As shown in the drawings, Figure 4 The cover 200 of the jet element 100 includes an outer edge portion 210 and a central portion 220.

[0041] The cover 200 is provided with an array of holes 211 and 222 corresponding to the liquid outlet, and a slit-shaped annular through-hole 231 corresponding to the gas outlet.

[0042] Specifically, the array of holes 211 on the outer edge portion 210 is arranged in a circular ring, which can be a single circular ring array or a multi-circular ring array. The position of the outer edge portion 210 corresponds to the fluid outlet of the third annular fluid chamber 160. In the Figure 4 In one non-limiting embodiment shown, the array of holes 211 includes three layers of ring arrays arranged at equal intervals, and each hole has a diameter of about 0.1-1 mm, such as about 0.5 mm.

[0043] Specifically, the central portion of the central portion 220 is provided with a fluid outlet 221 corresponding to the tubular fluid chamber 130. The fluid outlet 221 is circular, and can also be other shapes such as oval, triangular, quadrilateral, or polygonal, etc. On the central portion 220, the portion corresponding to the outlet of the first annular fluid chamber 140 is provided with an array of holes 222, which is arranged in a circular ring around the fluid outlet 221, which can be a single circular ring array or a multi-circular ring array. In the Figure 4 In one non-limiting embodiment shown, the array of holes 222 includes twelve layers of ring arrays arranged at equal intervals, and each hole has a diameter of about 0.1-1 mm, such as about 0.5 mm.

[0044] The slit-shaped annular through-hole 231 arranged between the outer edge portion 210 and the central portion 220 corresponds to the fluid outlet of the second annular fluid chamber 150.

[0045] In one non-limiting embodiment, the fluid inlet 141 of the first annular fluid chamber 140 and the fluid inlet 161 of the third annular fluid chamber 160 are respectively communicated with the liquid inlet 15 through pipelines to supply liquid (drinking water) into the first annular fluid chamber 140 and the third annular fluid chamber 160. The fluid inlet 131 of the tubular fluid chamber 130 and the fluid inlet 151 of the second annular fluid chamber 150 are respectively communicated with the gas inlet 16 through pipelines to supply gas (hydrogen) into the tubular fluid chamber 130 and the second annular fluid chamber 150.

[0046] During use, when the liquid fluid is pressurized, it will pass through the small hole array 222 and 211 at the fluid outlet end of the first annular fluid cavity 140 and the third annular fluid cavity 160, and then hit the plate body near the small holes at high speed. The liquid will be broken into atomized water droplets and discharged from the small holes, forming an atomized water atmosphere near the fluid outlet B and mixing with the gas spirally ejected from the gas outlets 221 and 231, achieving a better water-gas coupling state. At the same time, due to the interval arrangement of the gas outlet and the liquid outlet, the gas and the liquid are multi-layered coated near the outlet B, increasing the contact between the gas and the liquid, better improving the gas-liquid mixing degree, and the violent collision of the gas and the liquid can make the hydrogen bubbles break into smaller bubbles, thereby improving the solubility of hydrogen in water.

[0047] As shown in Figure 5 As another non-limiting embodiment, the cover body 200 includes an outer edge portion 210 at the outer periphery, a central portion 220 at the center, and optionally includes a connecting portion 230 connecting the outer edge portion 210 and the central portion 220. In order to realize the connection between the outer edge portion 210 and the central portion 220, one or more connecting portions 230 in the form of a narrow strip are arranged between the two, and the one or more connecting portions 230 divide the slit through hole 231 between 210 and 220 into two or more openings.

[0048] The outer edge of the cover body 200 corresponds to the outer edge of the outlet portion of the horn-shaped tube body 120. As another non-limiting embodiment, as shown in Figure 6 A horn-shaped cover 240 surrounding the cover body 200 is also provided to further improve the water-gas coupling degree of the fluid spirally ejected, and the outer wall of the horn-shaped cover 240 surrounding the cover body 200 can be arranged as an extension of the outer wall of the horn-shaped tube body 120.

[0049] The following will be described in detail Figures 1-6The non-limiting embodiments shown introduce the working principle of the present application. Liquid such as water enters the fluid chambers 140 and 160 from the fluid inlets 141 and 161, the water entering the fluid inlet 141 is accelerated by the turbine fan pressurizer 170, and then hits the cover central portion 220 near the fluid outlet end B via the chamber 140, the water is impacted to form mist liquid beads which are sprayed from the small hole array 222 on the cover; the water entering the fluid inlet 161 hits the cover peripheral portion 210 near the fluid outlet end B via the chamber 160, and the water is impacted to form mist liquid beads which are sprayed from the small hole array 211 on the cover. Pressurized gas such as hydrogen enters the fluid chambers 130 and 150 from the fluid inlets 131 and 151, the pressurized hydrogen entering the fluid inlet 131 is sprayed from the fluid outlet 221 of the fluid outlet end B, and meets the mist liquid beads sprayed from the peripheral small hole array 222, in addition, the pressurized hydrogen entering the fluid inlet 151 enters the second annular fluid chamber 150, and then the hydrogen forms a spiral fluid flow in the trumpet-shaped annular chamber, the hydrogen flow is spirally sprayed from the slit-shaped circular ring through-hole 231, and the spiral hydrogen flow impacts the mist liquid beads; at the same time, the mist water beads and the hydrogen flow are sequentially sprayed from the fluid outlets of the cover 200 which are arranged at intervals, and the multi-layer coating and uniform mixing of the gas and the liquid are realized.
