Technical Field

[0002] In various industrial and scientific fields, many liquids need to be purified, and ion exchange particles are used to remove impurity cations and impurity anions in the liquid to meet specific application requirements. For example, in the ultrapure water manufacturing process: in order to obtain water with the required purity, it is necessary to purify and remove impurity cations and impurity anions in the water. For example, in the semiconductor industry: etching liquid is often used in the production process of semiconductor devices.

[0030] 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.

[0031] As known from the background technology, in the actual ion exchange particle regeneration process, there is a problem of poor regeneration effect. The reasons for the poor regeneration effect are analyzed below.

[0032] like Figure 1 FIG. 1 is a schematic cross-sectional structure diagram of an ion exchange particle regeneration device, comprising:

[0033] The regeneration chamber 100 is used to accommodate the first ion exchange particles 101 and the second ion exchange particles 102 .

[0034] The regeneration chamber 100 includes a liquid inlet 103 and a liquid outlet 104 .

[0035] A first filter screen 105 is located at the liquid inlet 103 , and a second filter screen 106 is located at the liquid outlet 104 .

[0036] During the regeneration process, the first ion exchange particles 101 and the second ion exchange particles 102 are randomly mixed in the regeneration chamber 100, and the same regeneration liquid is introduced into the regeneration chamber 100. The regeneration liquid flows into the regeneration chamber 100 from the liquid inlet 103 and flows out of the regeneration chamber 100 from the liquid outlet 104. The first ion exchange particles 101 and the second ion exchange particles 102 are regenerated to restore their purification functions. There are the following problems:

[0037] For the sake of brevity and convenience of description, the first ion exchange particles 101 and the second ion exchange particles 102 are collectively referred to as particles.

[0038] First, the stack of first ion exchange particles 101 and second ion exchange particles 102 aggregates and / or agglomerates into a mass.

[0039] Since the first ion exchange particles 101 and the second ion exchange particles 102 are mixed together in a disorderly manner, the pressure on the particles at the bottom of the regeneration chamber 100 increases, and the probability of the particles in the bottom area 107 of the regeneration chamber 100 stacking, agglomerating and / or condensing into a mass increases, so that the regeneration liquid cannot fully contact with the particles at the bottom of the regeneration chamber 100, thereby reducing the regeneration effect of the particles. In addition:

[0040] (1) The particles that are stacked, aggregated and / or agglomerated increase the flow resistance of the regeneration liquid in the regeneration chamber 100, thereby reducing the regeneration effect and efficiency of the particles.

[0041] (2) The particles that are stacked, aggregated and / or agglomerated into agglomerates may clog the second filter screen 106, increase the flow resistance of the regeneration liquid in the regeneration chamber 100, and reduce the regeneration effect and efficiency of the particles.

[0042] Second, the first ion exchange particles 101 and the second ion exchange particles 102 cannot be regenerated independently.

[0043] Since the first ion exchange particles 101 and the second ion exchange particles 102 are randomly mixed together, the first ion exchange particles 101 and the second ion exchange particles 102 can only be regenerated using the same regeneration liquid. It is impossible to independently regenerate the first ion exchange particles 101 and the second ion exchange particles 102 corresponding to the impurity ions to be removed according to different impurity ions to be removed, thereby reducing the regeneration effect.

[0044] In view of the above technical problems, an embodiment of the present invention provides an ion exchange particle regeneration device, which can improve the regeneration effect and thus improve the purification effect.

[0045] An ion exchange particle regeneration device provided in an embodiment of the present invention includes: a cation exchange chamber, including a first area for accommodating first cation exchange particles, and a second area for accommodating second cation exchange particles; a first support plate, located in the second area, for supporting the second cation exchange particles, the second cation exchange particles are located above the first cation exchange particles; a vibration component, coupled to the cation exchange chamber, for driving the first cation exchange particles and the second cation exchange particles to vibrate when the ion exchange particles are regenerated.

[0046] In the ion exchange particle regeneration device shown in the present application, the first support plate is used to support the second cation exchange particles, and is also used to isolate the first cation exchange particles and the second cation exchange particles, preventing the second cation exchange particles from stacking on the first cation exchange particles, reducing the probability of aggregation and / or accumulation of lumps between the first cation exchange particles, thereby improving the regeneration effect of the first cation exchange particles and the second cation exchange particles; the vibration component is coupled to the cation exchange chamber, and drives the first cation exchange particles and the second cation exchange particles to vibrate when the ion exchange particles are regenerated, reducing the probability of aggregation and / or accumulation of lumps between the particles of the first cation exchange particles and between the particles of the second cation exchange particles, and also improving the regeneration effect of the first cation exchange particles and the second cation exchange particles.

[0167] In this embodiment, the first support plate 400 is located in the second area 204 . In other embodiments, the first support plate 400 may be located in the first connection area 205 .

[0168] In order to make the drawings concise and clear, and to more clearly show the structure of the first support plate 400, the cation exchange chamber 200 and the first support plate 400 are drawn separately, corresponding to Figure 2 and Figure 3 The area 400a within the second zone 204 is used to place the first support plate 400.

The side wall of the first support plate protrusion has a plurality of first support plate side wall protrusions. A first interval is provided between adjacent first support plate side wall protrusions, and the first interval is also provided on the first support plate between adjacent first support plate protrusions.

[0171] In this embodiment, the first support plate protrusions are evenly distributed on the first support plate. In other embodiments, they may be unevenly distributed, but this does not limit the present application.

[0172] The plurality of first support plate protrusions have the following beneficial effects: providing space for setting the first interval, reducing the flow resistance of the second cation regeneration liquid flowing through the second zone, thereby improving the regeneration effect.

[0173] The plurality of first support plate sidewall protrusions have the following beneficial effects: preventing the second cationic regeneration particles from moving to the first interval, thereby reducing the probability of the second cationic regeneration particles blocking the first interval.

[0174] The first partition has the following beneficial effect: it provides a flow channel for the second cation regeneration liquid to flow through the second zone 204.

[0175] In this embodiment, the first support plate 400 has two first support plate protrusions, namely a first support plate protrusion 401 and a first support plate protrusion 402. The first support plate protrusion 401 is oriented away from the cationic valve 208, and the first support plate protrusion 402 is oriented away from the cationic valve 208.

[0176] In this embodiment, the side wall of the first support plate protrusion 401 has four first support plate side wall protrusions, namely, the first support plate side wall protrusion 401a, the first support plate side wall protrusion 401b, the first support plate side wall protrusion 401c and the first support plate side wall protrusion 401d; the side wall of the first support plate protrusion 402 has four first support plate side wall protrusions, namely, the first support plate side wall protrusion 402a, the first support plate side wall protrusion 402b, the first support plate side wall protrusion 402c and the first support plate side wall protrusion 402d.

[0177] A first spacer is provided between adjacent protrusions on the side walls of the first support plate, and the first spacer is also provided on the first support plate between adjacent protrusions on the first support plate. For the convenience of description, the first spacer provided between adjacent protrusions on the side walls of the first support plate is a first spacer 403a, and the first spacer provided on the first support plate 400 between adjacent protrusions on the first support plate is a first spacer 403b.

[0178] The shape of the first interval includes: a square, a triangle, a polygon, a circle, and an ellipse. In this embodiment, the shape of the first interval is a square.

[0179] In this embodiment, a first spacer 403a is provided between the first support plate side wall protrusion 401a and the first support plate side wall protrusion 401b, a first spacer 403a is provided between the first support plate side wall protrusion 401c and the first support plate side wall protrusion 401d, a first spacer 403a is provided between the first support plate side wall protrusion 402a and the first support plate side wall protrusion 402b, and a first spacer 403a is provided between the first support plate side wall protrusion 402c and the first support plate side wall protrusion 402d; the first spacer 403b is provided on the first support plate 400 between the adjacent first support plate protrusions 401 and 402.

[0180] In this embodiment, the first support plate protrusion has a first support plate cavity 401e, and the first interval connects the second area 204 and the first connecting area 205, that is, the second area 204 is connected to the first interval 403a, the first interval 403a is connected to the first support plate cavity 401e, the first support plate cavity 401e is connected to the first connecting area 205, and the second area 204 is connected to the first interval 403b, and the first interval 403b is connected to the first connecting area 205.

[0181] In this embodiment, the first support plate 400 is detachably connected to the cation exchange chamber 200. The shape of the protrusion of the first support plate includes: one or more of a cylinder, a square cylinder and a truncated cone; in this embodiment, the shape of the protrusion of the first support plate is a truncated cone, and the bottom (large bottom) of the truncated cone with a larger bottom area is connected to the first support plate 400, which has the following beneficial effects:

[0182] First, it is convenient to take out the second cation exchange particles 203 between the adjacent protrusions of the first support plate. In the direction away from the cation valve 208 toward the second area 204, the space between the adjacent protrusions of the first support plate increases.

[0183] Second, the truncated cone provides more space for the first intervals, so that more first intervals can be designed on the raised side wall of the first support plate.

[0184] For example, the cylinder and the truncated cone share the same base with the largest bottom area, and the side area provided by the truncated cone is larger than the side area provided by the cylinder.

[0185] The shape of the protrusion on the side wall of the first support plate includes: an outwardly convex sphere, or a part of a sphere. In this embodiment, the shape of the protrusion on the side wall of the first support plate is a part of a sphere, that is, an outwardly convex curved surface.

[0186] In some embodiments, the side wall of the first support plate may include multiple layers of first support plate side wall protrusions, and the number of first support plate side wall protrusions of each layer increases layer by layer from the top (small bottom of the cone) to the bottom (large bottom of the cone), thereby providing more position space for the setting of the first interval, reducing the flow resistance of the second cation regeneration liquid flowing through the second zone, and further improving the regeneration effect.

[0187] refer to Figure 7 , Figure 7 It is a side wall expansion diagram of a first support plate protrusion in an embodiment of the present invention. In this embodiment, the first support plate protrusion 800 is in the shape of a truncated cone, and the side wall expansion diagram of the truncated cone is an annular sector SX. On the annular sector SX, the first support plate protrusion 800 may include 18 first support plate side wall protrusions 801, and first intervals 801a are provided between adjacent first support plate side wall protrusions 801. Adjacent first support plate side wall protrusions 801 are connected by side wall blocks CBK on the first support plate side wall.

[0188] Although in Figure 7 In the example, a support plate protrusion 800 includes four layers of first support plate side wall protrusions 801, and the number of first support plate side wall protrusions 801 in each layer is increased by one. However, in the specific implementation, the specific number and distribution of the first support plate side wall protrusions 801 are not limited. Figure 3 The illustrated case is that the protrusions of the first support plate include two layers of protrusions on the side walls of the first support plate.

[0189] In a specific implementation, for the first support plate, its base, the first support plate protrusion, and the first support plate side wall protrusion can be integrally formed.
