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

[0089] The existing liquid purification system has a 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 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 within the decationization chamber 102. The deanionization device 101 includes a deanionization chamber 106, a second liquid inlet 107 and a second liquid outlet 108 located on the deanionization chamber 106, and an anion exchanger 109 distributed within the deanionization chamber 106.

[0091] The water 110 to be purified enters the decationization chamber 102 through the first liquid inlet 103 of the decationization device 100, and passes through the cation exchanger 105 to purify and remove the impurity cations in the water 110. 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 passes through the anion exchanger 109 to purify and remove the impurity anions in the water. The purified liquid flows out from the second liquid outlet 108. Figure 1 The direction of the arrow shown is the flow direction of the water 110 .

[0092] In the actual process of making the cation exchanger 105, 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 the decationization chamber 102 acidic. The bicarbonate ions mixed in the water, under acidic conditions, come into contact with hydrogen ions to generate carbon dioxide gas, and the generated carbon dioxide gas is mixed in the water. Figure 1 The liquid purification system shown cannot remove carbon dioxide gas mixed in water, and thus cannot produce ultrapure water. Therefore, the purification effect of the liquid purification system is poor.

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 decationized liquid will be 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. In other words, the decationizing device, the degassing device, and the deanionizing device are connected in series, and the output end of the decationizing device is directly connected to the input end of the degassing device, or the output end of the decationizing device is connected to the input end of the deanionizing device, and the output end of the deanionizing device is 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, when the liquid flows through the edge 222 of the cone 220, the liquid will flow down along the side 223 of the cone 220. Due to the gravity of the liquid, the liquid will be dispersed on the side 223. The dispersed liquid is conducive to the separation of gas from the liquid. Figure 4 The gas is dispersed toward f1, f2, f3 and f4, 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 cones 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 vertebrae 220, the second row of dispersed units 2192 includes two vertebrae 220, and the third row of dispersed units 2193 includes one vertebrae 220. In other embodiments, the number of rows of dispersed units and the number of vertebrae can also be other, and can be 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] The gaps between adjacent vertebrae 220 in each row of vertebrae have the following beneficial effects: first, it facilitates the flow of liquid toward the bottom of the degassing chamber 215; second, it allows the liquid to collide with the dispersion unit multiple times, facilitating the separation of gas from the liquid and improving the liquid purification effect; and third, it facilitates the subsequent removal of gas from the liquid into the degassing chamber 215 by the fan.

[0130] Continue to refer Figure 2 , combined with Figure 3 , along the normal direction of the bottom surface of the degassing chamber 215 downward, the number of vertebrae in each row of vertebrae decreases, and between each row, the angle between the vertical line from the apex 221 (i.e., the tip 221) of the vertebrae to the bottom surface 224 of the vertebrae and the side 223 of the vertebrae increases, 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 two adjacent rows onto the bottom surface of the vertebrae in the lower row are located within the bottom surface of the vertebrae in the lower row. For example, the projections of the vertices 221 of the two vertebrae 2201 and 2202 in the first row of dispersed units 2191 onto 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 cone may be a cone or a pyramid. The base of the cone may be flat or convex. The sides of the cone may be inclined or concave. The top of the cone may be a pointed tip or a table. The base of the pyramid may be flat or convex. The sides of the pyramid may be inclined or concave. The top of the pyramid may be a pointed tip or a table.

[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 Figure b shows the three-dimensional structure of the cone, a cross-sectional view taken along a line 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 convex; the side 223 of the cone body 225 is concave; and the cone body 225 is a platform 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 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 convex, which is conducive to the flow of liquid toward the bottom of the degassing chamber 215 and facilitates the collection of the degassed liquid.

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

[0138] The platform structure without a pointed tip can control the flow rate of the liquid on the side 223 of the cone 220, facilitating the dispersion of the liquid along the side of the cone 220 and further allowing the gas in the liquid to escape into the degassing chamber 215. The principle is explained as follows: the sharper the tip of the cone and the smaller the radius of curvature, the faster the liquid on the side will converge at the tip. Small droplets will aggregate with larger droplets, hindering the dispersion of the liquid along the side of the cone.

[0139] refer to Figure 6 , another embodiment of the vertebral structure of the present invention. The vertebral body 220 is in the shape of a cone; the cone comprises a bottom surface 224 and a vertebral body 225. The bottom surface 224 of the cone is convex; the side edges 223 of the vertebral body 225 are concave; the vertebral body 225 is a platform structure without a sharp point. A cylindrical body 226 is disposed between the bottom surface 224 and the vertebral body 225.

[0140] A cylinder 226 is provided between the bottom surface 224 and the conical body 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 conical body and the side 223 of the conical body increases, and the probability of liquid flowing to the side of the conical body 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 conical body.

[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 toward 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 and the vertebral body of part or all of the vertebral bodies.

[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 trapezoidal GFDE. The square ACFG connects the convex surface ABC and the trapezoidal 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 as to discharge the gas separated from the liquid 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 within the chamber 200 to prevent organic matter from entering the degassing device 202 via the fan 301 and adhering to the inner walls of the degassing chamber 215 and / or the dispersion unit 219, thereby contaminating the liquid to be purified. This improves the purification effect of the liquid. For example, when purifying water to produce pure water, organic matter such as acetaldehyde and benzene within the chamber 200 may enter the degassing device 202 via the fan 301 and adhere to the inner walls of the degassing chamber 215 and / or the dispersion unit 219. Upon entering the degassing device 202, the acetaldehyde and benzene dissolve in the water, contaminating the water to be purified and 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 through 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 through the first pipe 304; the gas in the chamber 200 flows to the fan 301 through 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 operating principle of the controller 303 is as follows: when the concentration monitor 302 detects that the organic matter concentration in the chamber 200 is within the specified range, the controller 303 disconnects the first pipe 304 from the fan 301 and connects the second pipe 305 to the fan 301, causing the fan 301 to draw air from the chamber 200 into the degassing chamber 215. When the concentration monitor 302 detects that the organic matter concentration in the chamber 200 exceeds the specified range, the controller 303 disconnects the second pipe 305 from the fan 301 and connects the first pipe 304 to the fan 301, causing the fan 301 to draw air from outside the housing 201 into the degassing chamber 215.

[0152] Continue to refer Figure 2 The first filter 312 provided 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.

[0153] The first filter 312 mainly includes:

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

[0155] Continue to refer Figure 2 The second filter 313 is provided on the first pipe between the controller 303 and the first filter 312, and 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) includes 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 organic matter filter assembly structure.

[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 provided on the liquid collecting tank 314 and is used to monitor the liquid level in the liquid collecting tank 314. When the liquid level reaches a certain value, the liquid in the liquid collecting tank 314 is discharged into the de-anionization device 204.

[0163] The fan 301 can be disposed below all the dispersion units 219, with each dispersion unit 219 being located below the spraying portion 217. This has the following beneficial effect: it can remove gases with larger molecular weights that have escaped from the liquid. Compared to air, gases with larger molecular weights tend to accumulate at the bottom of the degassing chamber 215. The fan 301 can also be disposed between the dispersion units 219 and the spraying portion 217. This has the following beneficial effect: it can remove gases with smaller molecular weights that have escaped from the liquid. Gases with smaller molecular weights tend to accumulate 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. It can not only bring out the gas with a larger molecular weight out of the degassing chamber, but also bring out the gas with a smaller molecular weight out of the degassing chamber, which simplifies the process and improves 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 gases released from the liquid within the degassing chamber 215. In other embodiments, during the liquid purification process, the liquid purification and the blowing of air into the degassing chamber 215 by the fan 301 are performed simultaneously, thereby reducing the production cycle. It should be noted that before the air enters the degassing device 202, water-soluble gases such as carbon dioxide and sulfur dioxide are first removed from 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 the liquid into the degassing chamber 215 to further enhance the liquid purification effect.

[0167] The second embodiment of the liquid purification system has the following beneficial effects: First, the present invention's liquid purification system not only removes cations and anions from the liquid, but also removes gases from the liquid, thereby ensuring that the liquid meets the purification requirements and improving the liquid purification effect. Second, compared to the first embodiment of the liquid purification system, this embodiment's liquid purification system also removes gases from the anion removal device, further enhancing the liquid purification effect.

Second, compared to the first embodiment of the liquid purification system, this embodiment's liquid purification system also removes gases from the anion removal device, further enhancing the liquid purification effect.
