[0088] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0089] The existing liquid purification system has poor liquid purification effect during the purification process. Figure 1 , taking the production of ultrapure water as an example, the reasons for the poor liquid purification effect are analyzed.

[0090] In order to better obtain ultra-pure water, Figure 1The liquid purification system shown in the figure is used to purify water to produce ultrapure water. The liquid purification system includes: a decationization device 100 and a deanionization device 101. The decationization device 100 includes a decationization chamber 102, a first liquid inlet 103 and a first liquid outlet 104 located on the decationization chamber 102, and a cation exchanger 105 distributed in the decationization chamber 102.

[0091] The water 110 to be purified enters the decationization chamber 102 through the first liquid inlet 103 of the decationization device 100, and is purified and removed from the impurity cations in the water 110 by the cation exchanger 105. The water after the impurity cations are removed enters the deionization chamber 106 through the first liquid outlet 104 and the second liquid inlet 107 in sequence, and is purified and removed from the impurity anions in the water by the anion exchanger 109, and the purified liquid flows out from the second liquid outlet 108.

[0092] In the actual process of making the cation exchanger 105, an acid such as hydrochloric acid is used, and the hydrochloric acid will remain in the cation exchanger 105. When the water is purified, the residual hydrochloric acid will enter the water, making the water after passing through the decationization chamber 102 acidic, and the bicarbonate ions mixed in the water will contact with the hydrogen ions under acidic conditions to generate carbon dioxide gas, and the generated carbon dioxide gas will mix in the water. Figure 1 The liquid purification system shown cannot remove the carbon dioxide gas mixed in the water, and thus cannot obtain ultrapure water. Therefore, the aforementioned liquid purification system has a poor purification effect.

The liquid purification system using the embodiment of the present invention has the following beneficial effects: the output end of the decationization device is directly or indirectly connected to the input end of the degassing device, that is, the liquid after passing through the decationization device will directly or indirectly flow into the degassing device, and the gas in the liquid after the decationization device is removed by the degassing device to further purify the liquid, thereby improving the liquid purification effect.

[0094] It should be noted that the decationizing device, the degassing device and the deanionizing device are connected in series, and the output end of the decationizing device is directly or indirectly connected to the input end of the degassing device.

[0125] In this embodiment, the dispersion unit 219 adopts the cone 220, and the tip 221 of the cone 220 faces the bottom surface of the degassing chamber, which is conducive to the liquid being dispersed on the cone 220, so that the gas in the liquid is separated into the degassing chamber 215. The principle is as follows: Figure 4 As shown in FIG. 1 , when the liquid flows to the edge 222 of the cone 220, the liquid will flow downward along the side 223 of the cone 220. Since the liquid has gravity, the liquid will be dispersed on the side 223. The dispersed liquid is conducive to the separation of the gas from the liquid. Figure 4 The gas is dispersed toward f1, f2, f3 and f4 in the middle direction, which further separates the gas from the liquid and improves the liquid purification effect.

[0126] It should be noted that, for the sake of simplicity and clarity of the drawings, the liquid purification system of the embodiment of the present invention is illustrated by taking three rows of dispersion units and seven vertebrae as an example, but the present invention is not limited thereto.

[0127] refer to Figure 3 , the three rows of dispersed units include: a first row of dispersed units 2191, a second row of dispersed units 2192, and a third row of dispersed units 2193; the first row of dispersed units 2191 includes four cones 220, the second row of dispersed units 2192 includes two cones 220, and the third row of dispersed units 2193 includes one cone 220. In other embodiments, the number of rows of dispersed units and cones can also be other numbers, and are selected according to actual needs.

[0128] Continue to refer Figure 2 , combined with Figure 3There is a gap between adjacent vertebrae 220 in each row of vertebrae. For example, the gap between adjacent vertebrae 220 in the first row of dispersed units 2191 is d1, and the gap between adjacent vertebrae in the second row of dispersed units 2192 is d2.

[0129] There is a gap between adjacent vertebrae 220 in each row of vertebrae, which has the following beneficial effects: first, it is conducive to the liquid flowing to the bottom of the degassing chamber 215; second, the liquid collides with the dispersion unit multiple times, which facilitates the gas in the liquid to separate from the liquid, thereby improving the liquid purification effect. Third, it is conducive to the subsequent fan to remove the gas separated from the liquid into the degassing chamber 215.

[0130] Continue to refer Figure 2 , combined with Figure 3 , the number of vertebrae in each row of vertebrae decreases downward along the normal direction of the bottom surface of the degassing chamber 215, and the angle between the vertical line from the vertex 221 (that is, the tip 221 of the vertebrae) to the bottom surface 224 of the vertebrae and the side 223 of the vertebrae increases between each row, so that the liquid flowing through the vertebrae in the previous row can flow to the vertebrae of the subsequent dispersion unit and collide with the vertebrae, thereby improving the liquid purification effect. Figure 3 As shown, the liquid flowing through the first row of dispersion units 2191 can flow through the second row of dispersion units 2192 and / or the third row of dispersion units 2193 .

[0131] The projections of the vertices of at least two vertebrae in the upper row of each of two adjacent rows on the bottom surface of the vertebrae in the lower row are located within the bottom surface of the vertebrae in the lower row, so that all the liquid flowing through the vertebrae in the upper row flows to the vertebrae in the lower row and collides with the vertebrae in the lower row, further allowing the gas in the liquid to escape into the degassing chamber 215, thereby improving the liquid purification effect.

[0132] Continue to refer Figure 2 , combined with Figure 3 In this embodiment, the projections of the vertices 221 of the two vertebrae in the upper row of each two adjacent rows on the bottom surface of the vertebrae in the next row are located within the bottom surface of the vertebrae in the next row. For example, the projections of the vertices 221 of the two vertebrae 2201 and vertebrae 2202 in the first row of dispersed units 2191 on the bottom surface 224 of the vertebrae 2203 in the second row of dispersed units 2192 are located within the bottom surface 224 of the vertebrae 2203 in the second row of dispersed units 2192.

[0133] The shape of the cone includes a cone or a pyramid. The shape of the bottom of the cone includes a plane or a convex surface; the shape of the side of the cone includes: an inclined plane or a concave surface; the shape of the top of the cone includes a tip or a table structure. The shape of the bottom of the pyramid includes a plane or a convex surface; the shape of the side of the pyramid includes: an inclined plane or a concave surface; the shape of the top of the pyramid includes a tip or a table structure.

[0134] In this embodiment, the shape of the vertebral body 220 is a cone; Figure 5 , Figure 5 include Figure 5 a and Figure 5 b, where Figure 5 a is a schematic diagram of the three-dimensional structure of the cone, Figure 5 b is a cross-sectional view of the three-dimensional structure of the cone along the normal direction perpendicular to the bottom surface of the degassing chamber 215. The cone includes a bottom surface 224 and a cone body 225. The bottom surface 224 of the cone 220 is a convex surface; the side 223 of the cone body 225 is a concave surface; and the cone body 225 is a table structure without a tip.

[0135] Continue to refer Figure 5 , along the normal direction perpendicular to the bottom surface of the degassing chamber 215, the conical cross section is composed of a convex surface ABC and a trapezoid CDEA located below the convex surface and connected to the convex surface. The waist of the trapezoid CDEA is a concave surface.

[0136] The bottom surface 224 of the cone is a convex surface, which is conducive to the liquid flowing toward the bottom of the degassing chamber 215 and is convenient for collecting the degassed liquid.

[0137] The side edge 223 of the cone is a concave surface, which is conducive to the dispersion of liquid at the side edge 223 of the cone, so that the gas in the liquid can escape to the degassing chamber 215.

[0138] The platform structure without a tip can control the flow speed of the liquid on the side 223 of the cone 220, which is conducive to the dispersion of the liquid on the side of the cone 220, and further allows the gas in the liquid to escape to the degassing chamber 215. The principle is explained as follows: the sharper the tip of the cone with a tip, the smaller the radius of curvature of the tip, the faster the liquid at the side gathers at the tip, and small droplets will gather large droplets, which is not conducive to the dispersion of the liquid on the side of the cone.

[0139] refer to Figure 6 , is another embodiment of the vertebral structure of the present invention. The vertebral body 220 is in the shape of a cone; the cone includes a bottom surface 224 and a vertebral body 225, the bottom surface 224 of the cone is a convex surface; the side 223 of the vertebral body 225 is a concave surface; the vertebral body 225 is a table structure without a tip. A cylinder 226 is arranged between the bottom surface 224 and the vertebral body 225.

[0140] A cylinder 226 is arranged between the bottom surface 224 and the cone portion 225, which has the following beneficial effects: downward along the normal direction perpendicular to the bottom surface of the degassing chamber 215, the angle between the vertical line of the bottom surface 224 of the cone and the side 223 of the cone increases, and the probability of liquid flowing to the side of the cone decreases. The cylinder 226 can be used to control the flow direction of the liquid so that the liquid flows to the side of the cone.

[0141] The cylinder 226 is used to form a buffer between the bottom surface 224 of the cone and the side 223 of the cone. That is, the cylinder 226 can control the flow direction of the liquid so that the liquid flows to the side 223 of the cone 220, disperses the liquid, and allows the gas in the liquid to escape to the degassing chamber 215.

[0142] It should be noted that, according to actual needs, a cylinder 226 can be provided between the top surface of part or all of the vertebrae and the vertebrae.

[0143] Continue to refer Figure 6 , along the normal direction perpendicular to the bottom surface of the degassing chamber 215, the cross section of the cone 233 is composed of a convex surface ABC, a square ACFG and a trapezoid GFDE. The square ACFG connects the convex surface ABC and the trapezoid GFDE.

[0144] Continue to refer Figure 2 The degassing device includes: a fan device, used to discharge the gas separated from the degassing device 202 out of the shell, wherein the fan device includes: a fan 301; a concentration monitor 302, a controller 303, a first pipeline 304, a second pipeline 305, a first filter 312, and a second filter 313.

[0145] Continue to refer Figure 2 The fan 301 is connected to the degassing device 202 and is used to blow gas into the degassing device 202, so that the gas separated from the liquid can be discharged out of the degassing chamber 215.

[0146] It should be noted that the fan 301 blows gas into the degassing device 202. The gas comes from the gas in the chamber 200 or the gas outside the shell 201. In order to simplify the process and reduce the process cost, in this embodiment, the gas is air.

[0147] The concentration monitor 302 is connected to the controller 303 and is used to detect the concentration of organic matter in the chamber 200 .

[0148] It should be noted that the concentration monitor 302 monitors the concentration of organic matter in the chamber 200 in order to prevent the organic matter from entering the degassing device 202 through the fan 301 and adhering to the inner wall of the degassing chamber 215 and / or the dispersion unit 219, thereby contaminating the liquid to be purified, thereby improving the liquid purification effect. For example, when purifying water to make pure water, organic matter such as acetaldehyde and benzene in the chamber 200 enters the degassing device 202 through the fan 301 and adheres to the inner wall of the degassing chamber 215 and / or the dispersion unit 219. When the water enters the degassing device 202, the acetaldehyde and benzene dissolve in the water, contaminating the water to be purified, thereby reducing the purification effect.

[0149] Continue to refer Figure 2 One end 308 of the first pipe 304 and one end 309 of the second pipe 305 are connected to the fan 301 via the controller 303, and the other end 310 of the first pipe 304 is connected to the outside of the shell 201; the other end 311 of the second pipe 305 is placed in the chamber 200; the gas outside the shell 201 flows to the fan 301 via the first pipe 304; the gas in the chamber 200 flows to the fan 301 via the second pipe 305.

[0150] Continue to refer Figure 2 The controller 303 is used to control the connection between the first pipeline 304 and the second pipeline 305 and the fan 301.

[0151] The working principle of the controller 303 is as follows: when the concentration monitor 302 detects that the concentration of organic matter in the chamber 200 is not exceeded, the controller 303 controls the first pipe 304 to be disconnected from the fan 301, and controls the second pipe 305 to be connected to the fan 301, so that the fan 301 draws air from the chamber 200 into the degassing chamber 215. When the concentration monitor 302 detects that the concentration of organic matter in the chamber 200 is exceeded, the controller 303 controls the second pipe 305 to be disconnected from the fan 301, and controls the first pipe 304 to be connected to the fan 301, so that the fan 301 draws air from the outside of the housing 201 into the degassing chamber 215.

[0152] Continue to refer Figure 2 The first filter 312 disposed on the first pipe 304 at the housing 201 is used to filter the gas entering the first pipe 304. That is, the first filter 312 is used to filter and remove dust, mosquitoes, fluff and other debris in the gas.

[0154] The filter (not shown) is used to filter and remove dust, mosquitoes, and fluff in the gas.

[0155] Continue to refer Figure 2 The second filter 313 disposed on the first pipe between the controller 303 and the first filter 312 is used to filter the gas entering the fan 301 through the first pipe 304. The second filter 313 mainly filters organic matter in the gas after passing through the first filter 312. The second filter 313 contains an organic matter filtering component, which mainly includes:

[0156] A filter medium (not shown), the filter medium comprising: one or more of activated carbon, coral sand and zeolite. In this embodiment, the filter medium is activated carbon.

[0157] A filter container (not shown) is used to hold the filter medium.

[0158] The support frame (not shown) is used to fix the filter container and maintain the stability of the structure of the organic matter filter assembly.

[0159] A control system (not shown) is used to control the filtration process and monitor the filtration results.

[0160] Continue to refer Figure 2 The degassing device 202 includes a liquid collecting box 314. The liquid collecting box 314 is coupled to the second port 315 of the degassing chamber 215, and is used to collect the liquid separated by the dispersion unit.

[0161] Continue to refer Figure 2 The degassing device 202 includes an exhaust port 316 and a third pipe 318. The exhaust port 316 is coupled to the third port 317 of the degassing chamber 215, and is used to discharge the gas separated by the dispersion unit out of the housing 201 through the third pipe 318. The exhaust port 316 is located on the housing 201.

[0162] Continue to refer Figure 2 The degassing device 202 includes a liquid level meter 319. The liquid level meter 319 is disposed on the liquid collecting tank 314 and is used to monitor the liquid level in the liquid collecting tank 314.

[0163] The fan 301 can be arranged below all the dispersion units 219, and the dispersion units 219 are all located below the spraying part 217, which has the following beneficial effects: it can remove the gas with a large molecular weight separated from the liquid body, and compared with air, the gas with a large molecular weight is easy to gather at the bottom of the degassing chamber 215. The fan 301 can also be arranged between the dispersion unit 219 and the spraying part 217, which has the following beneficial effects: it can remove the gas with a small molecular weight separated from the liquid body, because the gas with a small molecular weight is easy to gather at the top of the degassing chamber 215.

[0164] Continue to refer Figure 2 In this embodiment, the fan 301 can be arranged under all the dispersion units 219, and the dispersion units 219 are all located under the spraying part 217, which can not only bring out the gas with a larger molecular weight but also bring out the gas with a smaller molecular weight, thereby simplifying the process and improving the liquid purification effect.

[0165] In this embodiment, after the liquid is purified, the fan 301 blows air into the degassing chamber 215 to remove the gas separated from the liquid in the degassing chamber 215. In other embodiments, during the liquid purification process, the process of purifying the liquid and the process of blowing air into the degassing chamber 215 by the fan 301 are carried out simultaneously, which saves the process production cycle. It should be noted that before the air enters the degassing device 202, it first removes water-soluble gases such as carbon dioxide and sulfur dioxide in the air to prevent contamination of the liquid to be purified. In other embodiments, the fan 301 can blow an inert gas that is not easily soluble in liquid into the degassing chamber 215, which can further improve the liquid purification effect.
