Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a modular ion exchange device for ultrapure water treatment. Background Technology

[0002] Ultrapure water production requires extremely high water purity, typically demanding very low levels of ions, conductivity, particles, and microorganisms. Ion exchange technology, a key component of ultrapure water treatment, primarily removes soluble inorganic ions from the water through cation and anion exchange, ensuring the effluent meets ultrapure water standards.

[0003] Some ion exchange devices commonly have the following problems:

[0004] When water flows into the resin bed, it is easy to form a biased flow along the top or inner wall of the equipment, resulting in low local exchange efficiency of the resin bed and affecting the overall stability of the effluent water quality. If problems such as resin blockage or scaling occur inside the equipment, there is a lack of structural warning mechanism. Monitoring is often required through electrical sensors, which is highly dependent and not conducive to the adaptation of some companies to non-electrical environments.

[0005] Therefore, we propose a modular ion exchange device for ultrapure water treatment to solve the existing problems. Utility Model Content

[0006] The purpose of this invention is to address the problems existing in the background technology by proposing a modular ion exchange device for ultrapure water treatment.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a modular ion exchange device for ultrapure water treatment, comprising a bottom cover, an annular shell, and a top cover. The bottom cover is disposed at the bottom end of the annular shell, and an inner annular seat is fixedly disposed on the bottom cover. A resin bed is filled in the middle layer inside the inner annular seat, and a rain shower plate is movably inserted into the upper layer inside the inner annular seat. Rain shower holes are equidistantly opened on the rain shower plate, and the top opening of the rain shower holes protrudes from the upper surface of the rain shower plate.

[0008] The top cover is fixedly installed at the top of the ring shell. An annular flow channel is opened inside the top cover. A flow guiding annular cavity is fixedly installed at the bottom opening of the annular flow channel. The bottom end of the flow guiding annular cavity is located between the inner ring seat and the ring shell.

[0009] Preferably, an overflow port is provided at the upper end of the ring shell, and an overflow pipe is fixedly provided on the overflow port. The height of the overflow port is higher than the upper surface of the inner ring seat.

[0010] Preferably, the top cover is provided with a water inlet, which is connected to the annular flow channel, and the bottom cover is provided with a water outlet, which is connected to the bottom end of the inner wall of the inner ring seat.

[0011] Preferably, a skirt is fixedly provided on the bottom cover, the skirt is bolted to the bottom end of the ring shell, and a sealing ring is provided at the contact position between the skirt and the ring shell.

[0012] Preferably, the lower inner layer of the inner ring seat is designed in a funnel shape, with the bottom opening of the funnel facing the water outlet.

[0013] Preferably, a flange is fixedly installed on both the inlet and outlet, and mounting holes are equally spaced on the flange.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the process of using the modular ion exchange device for ultrapure water treatment, the flanges of the inlet and outlet are fixedly connected to the designated positions of the ion exchange device for ultrapure water treatment by bolts. The ultrapure water to be treated enters the annular flow channel through the inlet, and then enters the space between the ring shell and the inner ring seat through the guiding effect of the flow guiding ring cavity. The design of the flow guiding ring cavity prevents the ultrapure water from flowing along the lower surface of the top cover.

[0016] After a certain amount of ultrapure water accumulates between the ring shell and the inner ring seat, it overflows from the upper surface of the inner ring seat onto the rain plate, and then falls onto the resin bed below through the rain holes. The design of the raised rain holes on the rain plate ensures that the wastewater is evenly distributed on the entire plate surface.

[0017] Special resin deeply removes ions from the ultrapure water, and the ultrapure water with ions removed finally flows out through the outlet.

[0018] The return water line is connected through the overflow pipe. When ultrapure water flows out through the overflow pipe, it is necessary to control the inlet water flow or to indicate that there is a blockage in the device. Personnel need to disassemble the bottom cover for inspection and repair or replace the resin bed.

[0019] In this invention, ultrapure water enters the annular flow channel through the inlet, and is then evenly guided between the annular shell and the inner annular seat by the guide ring cavity. This avoids the water flow directly impacting the lower surface of the top cover and causing short-circuiting. After passing through the buffer zone of the annular shell and the inner annular seat, the ultrapure water overflows from the inner annular seat onto the rain plate. The even distribution of the rain holes ensures that the water flow falls evenly onto the surface of the resin bed, greatly improving the utilization rate and exchange uniformity of the resin bed. The rain holes on the rain plate are designed with protrusions, which allows the ultrapure water to be fully dispersed on the plate surface, avoiding excessive or insufficient water flow in local areas, improving the overall water flow uniformity, and ensuring the stable working state of the resin bed.

[0020] With its overflow pipe structure, when there is excessive accumulation of ultrapure water or downstream blockage, the water flows out through the overflow pipe, creating a visual alert. Users can promptly control the inlet water flow or schedule maintenance. This eliminates the need for electrical sensors, simplifying the equipment structure, enhancing reliability, and making it suitable for environments with high humidity, corrosion, or no power supply.

[0021] The inlet and outlet are mechanically connected by flanges and bolts. The main body of the equipment adopts a detachable modular structure, which makes it easy to replace or repair components such as resin bed and flow guiding components individually without disassembling the entire equipment, thus reducing maintenance costs and workload.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] like Figures 1-5As shown, the present invention proposes a modular ion exchange device for ultrapure water treatment, including a bottom cover 1, an annular shell 2 and a top cover 3. The bottom cover 1 is installed at the bottom end of the annular shell 2 and is connected to the annular shell 2 by a skirt 4. The skirt 4 is fixed by bolts, and a sealing ring is provided at the contact position to ensure the airtightness of the device.

[0032] The top cover 3 is fixed to the top of the ring shell 2. The top cover 3 is provided with a water inlet 6, which is connected to the annular flow channel 10 inside the top cover 3. Ultrapure water enters from the water inlet 6 and first flows around the annular flow channel 10. A flow guiding annular cavity 11 is fixedly installed at the bottom opening of the annular flow channel 10. The flow guiding annular cavity 11 is arranged around the annular shell 2 and the inner ring seat 14. The ultrapure water is uniformly distributed by the flow guiding annular cavity 11 to prevent the ultrapure water from flowing along the lower surface of the top cover 3. Finally, the ultrapure water flows downward along the space between the annular shell 2 and the inner ring seat 14, forming an annular water flow buffer.

[0033] The inner ring seat 14 is fixed to the bottom cover 1. The interior of the inner ring seat 14 is divided into three layers: the lower layer is funnel-shaped, the middle layer is filled with a resin bed 13, and the upper layer is movably connected to the rain shower plate 12. Rain shower holes 15 are evenly spaced on the rain shower plate 12. The top opening of each rain shower hole 15 protrudes upward from the upper surface of the rain shower plate 12 to ensure uniform distribution of ultrapure water on the rain shower plate 12.

[0034] After the ultrapure water accumulates to a certain level between the ring shell 2 and the inner ring seat 14, it overflows along the upper surface of the inner ring seat 14 to the rain shower plate 12, and falls evenly into the resin bed 13 below through the rain shower holes 15, so as to achieve full contact between the ultrapure water and the resin bed 13, remove residual ions in the ultrapure water, and complete the deep treatment.

[0035] The ultrapure water treated by the resin bed 13 is concentrated and drawn from the lower funnel-shaped inner ring seat 14, with the bottom opening facing the outlet 9, and the water flows out smoothly.

[0036] Example 2

[0037] like Figures 1-5 As shown, the modular ion exchange device for ultrapure water treatment proposed in this utility model, compared with Embodiment 1, further includes: an overflow port is provided at the upper end of the ring shell 2, the overflow port is connected to the overflow pipe 5, and the height of the overflow port is higher than the upper surface of the inner ring seat 14. When water flow abnormally accumulates or the downstream pipeline is blocked, ultrapure water is discharged from the overflow pipe 5, forming a visual prompt to remind the user to check the inlet water flow or perform equipment maintenance in time.

[0038] Flanges 8 are fixedly installed on both the inlet 6 and the outlet 9. Mounting holes 7 are equally spaced on the flanges 8 to facilitate the secure connection of the inlet 6 and the outlet 9 to the external pipeline by bolts.

[0039] With the above structure, ultrapure water achieves a reasonable flow direction, uniform distribution, and sufficient exchange within the equipment, significantly improving the utilization rate and exchange efficiency of the resin bed 13. At the same time, the modular disassembly structure allows for quick replacement of components such as the resin bed 13 and the rain shower plate 12, facilitating daily maintenance and repair, and reducing operating costs and maintenance intensity.

[0040] The above specific embodiments are merely several preferred embodiments of this utility model.
