Description

Technical Field

[0001] This utility model relates to the technical field of boron removal devices, and specifically to a boron removal device. Background Technology

[0002] Using resin columns for boron removal from fluid products is a highly efficient and economical method, particularly suitable for applications with extremely high boron content requirements, such as the semiconductor, photovoltaic, and pharmaceutical industries. This boron removal process can consistently reduce boron levels in product fluids to extremely low levels, meeting the demands of high-end manufacturing and environmental protection.

[0003] After the boron removal resin column is used, it needs to be rinsed to remove residual impurities. In the existing technology, the boron removal resin column is rinsed in a forward direction until the effluent meets the requirements, and then it can be put back into use. However, simply rinsing the boron removal resin column in a forward direction will not leave some residual impurities inside, resulting in poor cleaning effect and affecting the next use of the boron removal resin column. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a boron removal device that solves the problem of poor removal effect of residual impurities in the boron removal resin column in the prior art.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a boron removal device, comprising: A deboronizing resin column, used for deboronizing fluid products; An input pipeline, wherein a first control valve, a second control valve, and a third control valve are sequentially connected from the front end to the rear end of the input pipeline, and the rear end of the input pipeline is connected to the feed end of the boron removal resin column; and, The output pipeline is connected in sequence from the front end to the end of the pipeline to a fourth control valve, a fifth control valve, and a sixth control valve. The front end of the output pipeline is connected to the discharge end of the deboronized resin column.

[0006] In some embodiments, a filter is also included, which is connected to the output line and is located downstream of the sixth control valve.

[0007] In some embodiments, a seventh control valve is also included, which is connected to the output line and is located downstream of the filter.

[0008] In some embodiments, the deboronized resin column includes a shell and an adsorbent resin. A cavity is provided inside the shell. The top and bottom of the shell are respectively provided with an inlet end and an outlet end communicating with the cavity. The adsorbent resin fills the cavity.

[0009] In some embodiments, the adsorbent resin is Tulsimer® CH-99, DuPont AmberTec UP7530, LS-6000, or D870.

[0010] In some embodiments, a perforated plate is fixed to the bottom of the housing, the perforated plate being used to support the adsorbent resin inside the cavity.

[0011] In some embodiments, an aluminum oxide layer is provided on the inner wall of the housing and the mesh plate.

[0012] In some embodiments, a heat insulation mechanism is also included, which is fitted onto the outside of the housing.

[0014] In some embodiments, the first control valve, the second control valve, the third control valve, the fourth control valve, the fifth control valve, the sixth control valve, and the seventh control valve are all manual valves or solenoid valves.

[0016] Figure 1 This is a schematic diagram of the structure of a boron removal device provided by this utility model; Figure 2 This is a schematic diagram of the internal structure of the deboronized resin column provided by this utility model. Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] To address the technical problem of ineffective removal of residual impurities from boron-removing resin columns in existing technologies, this solution provides a boron removal device capable of performing both forward and backwashing on the boron-removing resin column, effectively removing residual impurities from within the column.

[0019] Please see Figures 1-2 , Figures 1-2 A boron removal device according to one embodiment of the present invention includes a boron removal resin column 1 and an input pipeline 2. The boron removal resin column 1 is used to remove boron from fluid products. A first control valve 21, a second control valve 22, and a third control valve 23 are sequentially connected from the front end to the end of the input pipeline 2, and the end of the input pipeline 2 is connected to the feed end of the boron removal resin column 1. A fourth control valve 31, a fifth control valve 32, and a sixth control valve 33 are sequentially connected from the front end to the end of the output pipeline 3, and the front end of the output pipeline 3 is connected to the discharge end of the boron removal resin column 1.

[0020] In actual use, when it is necessary to perform forward washing on the boron-removing resin column 1, the first control valve 21, the third control valve 23, the fifth control valve 32, and the sixth control valve 33 can be closed, and the second control valve 22 and the fourth control valve 31 can be opened. Pure water is then supplied to the input pipeline through the second control valve 22, and the boron-removing resin column is forward-washed for 30 minutes at a flow rate of 0.8-1.6 m³ / h. When backwashing the boron-removing resin column 1, the fourth control valve 31, the sixth control valve 33, the second control valve 22, and the first control valve 21 can be closed, and the fifth control valve 32 and the third control valve 23 can be opened. Pure water is then supplied to the output pipeline through the fifth control valve 32, and the boron-removing resin column is backwashed for 30 minutes at a flow rate of 1.6-2 m³ / h.

[0021] It is understandable that after rinsing with ultrapure water, the pH value of the ultrapure water can be tested using precision pH test paper.

[0022] In addition, by closing the second control valve 22, the third control valve 23, the fourth control valve 31 and the fifth control valve 32, and opening the first control valve 21 and the sixth control valve 33, the fluid product is transported to the input pipeline 2 via the first control valve 21. The fluid product enters the deboronized resin column 1, where the resin can adsorb and remove the boron molecules in the fluid product. The deboronized fluid product can then be discharged via the output pipeline 3.

[0023] It should be noted that, in one embodiment, a filter 4 is also included, which is connected to the output pipeline 3 and located downstream of the sixth control valve 33. Specifically, after the fluid product has undergone deborization, the boron concentration has decreased, but residual microparticles may still clog the pipeline; installing a filter can significantly reduce this risk.

[0024] In addition, in one embodiment, a seventh control valve 5 is also included, which is connected to the output line 3 and is located downstream of the filter 4.

[0025] It should be noted that the deboronizing resin column 1 is not limited to a specific structure. In one embodiment, the deboronizing resin column 1 includes a shell 11 and an adsorption resin 12. A cavity is provided inside the shell 11. The top and bottom of the shell 11 are respectively provided with an inlet end and an outlet end communicating with the cavity. The adsorption resin 12 fills the cavity, and the fluid product is deboronized by the adsorption resin 12.

[0026] In addition, it should be noted that the adsorption resin 12 is Tulsimer® CH-99. Of course, in other embodiments, the adsorption resin 12 may also be DuPont AmberTec UP7530, LS-6000 or D870.

[0027] Tulsimer® CH-99 is a styrene-divinylbenzene crosslinked resin with unique amine polyhydroxyl functional groups, which can form stable five-membered ring complexes with borate ions in the pH range of 5-9. Its high selectivity ensures efficient adsorption even at low boron concentrations.

[0028] Specifically, AmberTec UP7530 employs a methylglucosamine structure and achieves efficient boron removal by forming a stable five-membered ring chelate with borate ions under pH 5-9 conditions.

[0029] Specifically, the LS-6000 has a high exchange capacity and can efficiently remove boron ions over a wide pH range.

[0030] Specifically, D870 is a general-purpose ion exchange resin with good physical stability and uniform particle size distribution, providing stable boron removal performance. Its structure contains functional groups, enabling it to achieve separation, displacement, purification, concentration, and enrichment of exchanged substances through ion exchange and adsorption.

[0031] It should be noted that, in one embodiment, a perforated plate 111 is fixedly provided at the bottom inside the housing 11, and the perforated plate 111 is used to support the adsorption resin 12 inside the cavity.

[0032] The top of the housing 11 is also equipped with a pressure relief valve connected to the housing 11.

[0033] In addition, based on the above scheme, an aluminum oxide layer is provided on the inner wall of the shell 11 and the mesh plate 111, which can improve the corrosion resistance of the deboronized resin column 1.

[0034] It should be noted that, in order to prevent the adsorbent resin 12 inside the shell 11 from freezing due to low winter temperatures, a heat insulation mechanism 6 is specifically included, which is fitted onto the outside of the shell 11. Preferably, the heat insulation mechanism 6 is a heat insulation cotton layer.

[0035] When the resin is not used for a long time, there needs to be a certain liquid level inside the shell 11 to keep the resin moist. In addition, the physical integrity of the adsorption resin 12 needs to be maintained. The adsorption resin 12 should be protected from violent vibration or collision during storage. At the same time, care should be taken to avoid the adsorption resin 12 being tilted for a long time to avoid uneven resin distribution, which would affect the separation effect when used again.

[0036] In this embodiment, the first control valve 21, the second control valve 22, the third control valve 23, the fourth control valve 31, the fifth control valve 32, the sixth control valve 33, and the seventh control valve 5 are all solenoid valves. In other embodiments, the first control valve 21, the second control valve 22, the third control valve 23, the fourth control valve 31, the fifth control valve 32, the sixth control valve 33, and the seventh control valve can also be manual valves.

[0037] It should be noted that the second control valve 22 and the third control valve 23 are respectively installed on the two first branches of the input pipeline 2; the fourth control valve 31 and the fifth control valve 32 are respectively installed on the two second branches of the output pipeline 3.

[0038] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
