Description

Technical Field

[0001] The present invention relates to the technical field of electrodeionization, and more specifically, to an electrodeionization ultrapure water device and a control method thereof. Background Art

[0002] Ultrapure water is water that has undergone a series of physical and chemical treatments to reduce impurities such as ions, organic matter, particles, microorganisms, dissolved gases, etc. to extremely low levels. Ultrapure water is used in many fields, such as: semiconductor manufacturing (used in key links such as cleaning, etching, and doping to ensure the yield and reliability of semiconductor products), biotechnology and medicine (as a component of solvents or culture media to ensure that no impurities that may interfere with biological activity or experimental results are introduced), the power industry (especially in nuclear power plants, used as coolants and chemical reagents to maintain the safe and efficient operation of nuclear reactors), etc. At the same time, with the development and technological progress of the pharmaceutical, electronic, semiconductor, chemical and other industries, the demand for high-purity water is also increasing. Therefore, the equipment used to produce ultrapure water has also been improved with the development of science and technology.

[0003] Among them, EDI is an indispensable device for producing ultrapure water. However, when the EDI device performs electro-deionization on water, scaling of the resin often occurs, especially when the concentration of calcium and magnesium ions in the water is high. They are easy to exchange with the anions and cations in the resin, and form insoluble salts such as calcium carbonate and magnesium carbonate on the surface of the resin, causing the resin to scale and form lumps. Resin scaling will block the water production channel, increase the resistance of water flow through the resin layer, and thus cause a significant decrease in water production. The scaled resin will reduce its ion exchange capacity, increase the ion content in the effluent water, and the water quality will not meet the standards. Especially for applications that require high-purity water, such as semiconductor manufacturing, pharmaceutical production, etc., the decline in effluent water quality will directly affect the quality and performance of the product.

[0004] For example, the Chinese patent with application number CN202322347300.4 is an improvement on the resin scaling problem, but it only cleans the surface of the resin plate, and does not solve the resin scaling inside it at all. Therefore, the EDI device will still experience a significant decrease in water production, an increase in the ion content in the effluent, and substandard water quality.

The sealing plate and the auxiliary movable plate close to the scaling block will be separated due to the water pressure (because in the initial setting, the tension of the second tension spring is equal to the normal water pressure, so when the local water pressure increases, the water will enter the broken block, thereby causing the broken block to separate from the auxiliary movable plate). Therefore, when the two broken blocks are close to each other, the resin that has scaled into blocks will be broken apart, thereby causing the water to flow normally.

[0018] 2. In the electric deionization ultrapure water equipment, when the water pressure acts on the sealing driving hemispherical cover, it will cause its broken block to move in the direction away from the auxiliary moving plate, and at the same time, it will cause its sealing plate to tilt. Therefore, when the sealing plate tilts, it will tilt with the auxiliary sealing cylinder. At the same time, when one end of the auxiliary sealing cylinder tilts, the other end will tilt. Therefore, the auxiliary sealing cylinder will close the two first connecting grooves near the tilted end (when the auxiliary sealing cylinder is in the initial position, the auxiliary sealing cylinder has closed half of the first connecting groove). Therefore, when the driving groove is subjected to water pressure When it continues to increase, the inclination angle of the sealing plate will become larger and larger, and finally the driving groove will be connected with the limit card channel, so that the liquid will pass through the auxiliary driving cylinder into the pressure groove on the side of the sealing plate away from the auxiliary movable plate, and finally will pass through the annular channel, the first connecting groove, the first connecting channel and the second connecting channel in sequence into the crushing barrel, so that when the two crushing barrels at the upper end away from the sealing plate are subjected to water pressure, the two crushing blocks can be prompted to move relative to each other and move closer to each other at the same time, so that the scaling blocks can be crushed more accurately and delicately, so that the water flow can be promoted to flow better.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1 When the EDI device performs electro-deionization on water, scaling of the resin often occurs. Especially when the concentration of calcium and magnesium ions in the water is high, they are easy to exchange with the anions and cations in the resin and form insoluble salts such as calcium carbonate and magnesium carbonate on the surface of the resin, causing the resin to scale and form lumps. The resin scaling will block the water production channel, increase the resistance of water flow through the resin layer, and thus cause a significant decrease in water production. The scaled resin will reduce its ion exchange capacity, increase the ion content in the outlet water, and the water quality will not meet the standards. This embodiment is specially invented to solve the above problems.

[0036] See also Figures 1 to 14 The present invention provides a technical solution: an electrodeionized ultrapure water device, comprising an EDI body 1 and a concentrated water partition 3 and a fresh water partition 2 alternately arranged in the EDI body 1, and diaphragms are arranged on the fresh water partition 2 and the concentrated water partition 3, wherein the diaphragms are a negative membrane 4 and a positive membrane 6, and are also alternately arranged, and at the same time, the working principles of the fresh water partition 2, the concentrated water partition 3, the positive membrane 6 and the negative membrane 4 are all existing technologies, so they are not described in detail, and the rear side of each concentrated water partition 3 and the fresh water partition 2 is provided with a hollow crushing layer with a moving direction backward, and the inner wall of the concentrated water partition 3 and the fresh water partition 2 is provided with a hollow crushing layer with a moving direction forward, and the hollow crushing layer includes a plurality of crushing blocks 9 that can move forward and backward independently, and each adjacent two crushing blocks 9 are spherically jointed with a retractable connecting component, and the crushing blocks 9 with a moving direction forward and the crushing blocks 9 with a moving direction backward are staggered.

[0037] The hollow crushing layer moving in the forward direction also includes a mounting plate 5 arranged on the inner side walls of the fresh water baffle 2 and the concentrated water baffle 3, wherein the mounting plate 5 is clamped on the fresh water baffle 2 and the concentrated water baffle 3, and the clamping position is to avoid the water inlet and the water outlet, and the anion membrane 4 or the cation membrane 6 can be stabilized on the corresponding baffle through the mounting plate 5, and the side of each crushing block 9 close to the diaphragm is connected to the auxiliary moving plate 7 for sliding forward and backward, wherein the side of the auxiliary moving plate 7 close to the crushing block 9 is in contact with the crushing block 9, and the auxiliary moving plate 7 is away from the crushing A first auxiliary fixed circular plate 32 is slidably connected to one side of the block 9, and a first fixed rod 8 is fixedly connected between two adjacent first auxiliary fixed circular plates 32, and the first auxiliary fixed circular plate 32 closest to the inner wall of the fresh water partition 2 and the inner wall of the concentrated water partition 3 is also fixedly connected to the fresh water partition 2 and the concentrated water partition 3 through the first fixed rod 8, and the first auxiliary fixed circular plate 32 closest to the inner wall of the mounting plate 5 is also fixedly connected to the mounting plate 5 through the first fixed rod 8, so the first auxiliary fixed circular plate 32 on each hollow crushing layer is fixed.

[0038] The auxiliary movable plate 7 is fixedly connected to the center of one side of the first auxiliary fixed circular plate 32 with an auxiliary limiting plate 16, and the auxiliary limiting plate 16 is slidably connected in the first auxiliary fixed circular plate 32, wherein the auxiliary limiting plate 16 is in the shape of a circular plate, and the shape of the groove in the first auxiliary fixed circular plate 32 is also in the shape of a circular plate, except that the auxiliary limiting plate 16 can slide in any direction in the groove, so when the crushing block 9 is subjected to external force, it will move with the auxiliary movable plate 7.

[0039] A first cross partition plate 15 is fixedly connected to the center of the auxiliary movable plate 7 close to the crushing block 9, and a second cross partition plate 17 is slidably connected to the end of the first cross partition plate 15 away from the auxiliary movable plate 7, and a sealing plate 19 is provided at the end of the second cross partition plate 17 away from the first cross partition plate 15.

[0040] An auxiliary connecting cylinder 34 is fixedly connected to one end of the first cross dividing plate 15 close to the second cross dividing plate 17, and a second auxiliary fixed circular plate 35 capable of sliding in the second cross dividing plate 17 is fixedly connected to one end of the auxiliary connecting cylinder 34 away from the first cross dividing plate 15, wherein the auxiliary connecting cylinder 34 and the second cross dividing plate 17 are slidably connected, and a second tension spring 36 with one end arranged on the inner side surface of the second cross dividing plate 17 is fixedly connected to one side of the second auxiliary fixed circular plate 35 away from the auxiliary connecting cylinder 34.

[0041] Therefore, when scaling occurs in a certain part of the resin layer, the water pressure around the scaling block will increase, so the sealing plate 19 and the auxiliary movable plate 7 close to the scaling block will be separated due to the water pressure (because in the initial setting, the tension of the second tension spring 36 is equal to the normal water pressure, so when the local water pressure increases, water will enter the crushing block 9, thereby causing the crushing block 9 to separate from the auxiliary movable plate 7). Therefore, when the two crushing blocks 9 are close to each other, the resin scaling blocks will be broken up, thereby allowing the water to flow normally.

[0042] Embodiment 2 Although the resin scaling blocks can be crushed in the above embodiment, the structural blocks may not appear directly opposite the crushing block 9. Therefore, when the scaling blocks are crushed, the connecting components often play a role. Therefore, the crushing effect is relatively poor and the scaling blocks cannot be accurately squeezed. Therefore, in order to be able to crush the resin scaling blocks better and more accurately, this embodiment is specially invented.

[0043] See also Figures 1 to 14On the basis of the above embodiment, the adopted technical solution includes a connecting component, which includes a first limiting ball head 12 uniformly fixedly connected to the outer peripheral surface of the crushing block 9, the outer peripheral surface of the crushing block 9 is spherically hinged with a crushing barrel 10 through the first limiting ball head 12, and the opposite ends of two adjacent crushing barrels 10 are slidably connected with a crushing column 11, and both ends of the crushing column 11 are provided with a first tension spring 13 fixedly connected to the corresponding crushing barrel 10, wherein when the crushing block 9 moves toward the resin that has been scaled and agglomerated, the crushing barrel 10 will rotate on the first limiting ball head 12, and the crushing barrel 10 and the crushing column 11 will slide.

[0044] A pressure groove is opened at the center of the crushing block 9 near the auxiliary movable plate 7, the first cross partition plate 15 and the second cross partition plate 17 are both arranged in the pressure groove, and the four end faces of the first cross partition plate 15 and the second cross partition plate 17 are all in contact with the inner circumferential surface of the pressure groove, and a sealing plate 19 that can be tilted toward the angle between two adjacent connecting parts is provided on the side of the second cross partition plate 17 away from the first cross partition plate 15, and the outer circumferential surface of the sealing plate 19 is in contact with the inner circumferential surface of the pressure groove.

[0045] The second cross partition plate 17 is fixedly connected with a second limiting ball head 18 at the center away from one side of the first cross partition plate 15, and the sealing plate 19 is hinged on the second cross partition plate 17 through the second limiting ball head 18, so that the sealing plate 19 can be tilted in the directions of four angles, and the inner circumference of the pressure groove is provided with an annular limiting groove adapted to the sealing plate 19, and the shape of the outer circumference of the sealing plate 19 is a spherical surface with the second limiting ball head 18 as the center, and the inner circumference of the annular limiting groove is evenly provided with four limiting channels, each of which is arranged on the angle line of two adjacent connecting parts, and the outer circumference of the sealing plate 19 is evenly fixedly connected with a plurality of auxiliary driving cylinders 21, and each auxiliary driving cylinder 21 is respectively slidably connected to the opposite side. In the corresponding limiting card track, a cross channel 25 is opened in the middle of the auxiliary driving cylinder 21, and the four auxiliary driving cylinders 21 are rotatably connected at one end away from the sealing plate 19 to an auxiliary sealing cylinder 20 with the second limiting ball head 18 as the sphere center, and the auxiliary sealing cylinder 20 is slidably connected in the crushing block 9, wherein the setting of the limiting card track and the auxiliary driving cylinder 21 can make the sealing plate 19 only tilt in the direction of the angle line between the two connecting parts, and the auxiliary driving cylinder 21 can make the auxiliary sealing cylinder 20 tilt along with the sealing plate 19 when it tilts (the sealing plate 19 takes the second limiting ball head 18 as the sphere center, and the auxiliary sealing cylinder 20 also takes the second limiting ball head 18 as the sphere center).

[0046] An annular channel 26 is provided at one end of the inner circumference of the pressure groove away from the auxiliary movable plate 7, a first connecting channel 14 is provided on the outer circumference of the first limiting ball head 12, and a second connecting channel 22 connected to the first connecting channel 14 is provided on the inner side wall of the crushing barrel 10, and a first connecting groove 31 connected to the first connecting channel 14 is provided on the outer circumference of the crushing block 9, and the first connecting groove 31 is also connected to the annular channel 26.

[0047] A sealing driving hemispherical cover 23 with the second limiting ball head 18 as the sphere center is fixedly connected to the side of the sealing plate 19 close to the second cross partition plate 17, and the end of the sealing driving hemispherical cover 23 away from the sealing plate 19 is slidably connected in the second cross partition plate 17 (such as Figure 5 As shown, no matter when the sealing driving hemispherical cover 23 moves in any direction along with the sealing plate 19, the end of the sealing driving hemispherical cover 23 that is slidably connected to the second cross partition plate 17 will not come out of the second cross partition plate 17, thereby preventing liquid from entering the sealing driving hemispherical cover 23). The outer surface of the sealing driving hemispherical cover 23 is evenly provided with a plurality of driving grooves 24 that can be connected to the limit card channel. Through the setting of the driving grooves 24, when the liquid enters the crushing block 9, the water pressure can act on the sealing driving hemispherical cover 23. The outer peripheral surface of the second cross partition plate 17 is evenly fixedly connected to one end away from the first cross partition plate 15 with a plurality of auxiliary support plates 29. One side of the auxiliary support plate 29 is fixedly connected to a first spring 30 with one end arranged on the sealing plate 19. The second auxiliary fixing circle A second fixed rod 28 is fixedly connected to one side of the plate 35 near the second limiting ball head 18, one end of which passes through the second cross dividing plate 17 and the second limiting ball head 18 in sequence and extends to the crushing block 9, wherein the second fixed rod 28 and the second limiting ball head 18 are slidably connected, and the second fixed rod 28 and the second cross dividing plate 17 are also slidably connected, and the end of the second fixed rod 28 away from the second limiting ball head 18 is fixedly connected to a blocking block 27, and the crushing block 9 is provided with a plurality of pressure relief ports on the side away from the auxiliary movable plate 7, wherein the number of the pressure relief ports is two and they are relatively opened, and an auxiliary pressure relief groove connected to the pressure relief port is provided at the center of the inner side surface of the pressure groove, and the blocking block 27 is slidably connected in the auxiliary pressure relief groove, wherein a one-way valve is provided at the end of the pressure relief port away from the second limiting ball head 18, so that the liquid can only flow out from the crushing block 9.

[0048] When the water pressure acts on the sealing driving hemispherical cover 23, the crushing block 9 will be moved away from the auxiliary movable plate 7, and the sealing plate 19 will be tilted. Therefore, when the sealing plate 19 tilts, the auxiliary sealing cylinder 20 will be tilted together. At the same time, when one end of the auxiliary sealing cylinder 20 tilts, the other end will tilt. Therefore, the auxiliary sealing cylinder 20 will close the two first connecting grooves 31 near the tilted end (when the auxiliary sealing cylinder 20 is in the initial position, the auxiliary sealing cylinder 20 has closed half of the first connecting grooves 31). Therefore, when the water pressure on the driving groove 24 continues to increase, the sealing plate 19 will tilt with the auxiliary sealing cylinder 20. The inclination angle of 9 will become larger and larger, and finally the driving groove 24 will be connected with the limit card channel, so that the liquid will pass through the auxiliary driving cylinder 21 into the pressure groove on the side of the sealing plate 19 away from the auxiliary movable plate 7, and finally enter the crushing barrel 10 through the annular channel 26, the first connecting groove 31, the first connecting channel 14 and the second connecting channel 22 in sequence, so that the two crushing barrels 10 at the upper end away from the sealing plate 19 can cause the two crushing blocks 9 to move relative to each other and move closer to each other when subjected to water pressure. Therefore, the scaling blocks can be crushed more accurately and delicately, so that the water flow can be promoted to flow better.

[0049] Embodiment 3 Although the above embodiment can accurately break up the scaling blocks, some scaling debris will remain in the resin layer after breaking up. When these debris exist in the water layer for a long time, the risk of causing scaling will be greatly increased. Therefore, in order to discharge the broken scaling particles, this embodiment is specially invented.

[0050] See also Figures 1 to 14 On the basis of the above embodiment, the technical solution adopted includes that when personnel need to discharge the broken scaling particles, personnel need to connect the water inlet on the EDI body 1 to a device that can emit pulse water, wherein the device that can emit pulse water is a commonly used model on the market, and it is also a prior art, so it will not be described in detail. When the pulse water enters the EDI body 1, the hollow crushing layer will shake as a whole, and when the pulse water acts on the resin particles, the whole will also vibrate, so through the nut effect principle, the broken small scaling will go down. Move, and at the same time, because the pulse water is high-pressure water, the sealing plate 19 on the hollow crushing layer will also move when it is subjected to high-pressure water. Therefore, when the relative sealing plates 19 move relatively, the resin is shaken while the scaling resin is continuously destroyed, so that the scaling can be better broken up, and the broken scaling can be better discharged from the liquid outlet. At the same time, the liquid outlet is also connected to the wastewater pipe at this time, so when the scaling is discharged, the resin layer can be promoted to better carry out ion transfer without affecting the normal circulation of water.

[0051] Embodiment 4 On the basis of the above embodiment, this embodiment further provides a control method for an electrodeionized ultrapure water device, comprising the following specific steps: S1. Open the water inlet valve to allow the water to be ionized to enter the EDI body 1; S2. When the EDI body 1 continues to work, ultrapure water will be continuously discharged, and concentrated brine will also be continuously discharged; S3. When a scaling block appears locally in the resin layer of the EDI body 1, the crushing block 9 will move and then crush the agglomerate; S4. Finally, when the personnel need to discharge the broken scaling debris, the personnel need to connect the water inlet to the pulse water pipe, thereby injecting pulse water into the EDI body 1, so that the scaling debris will be discharged from the EDI body 1 together with the water.

[0052] To sum up, when the electrodeionization ultrapure water equipment is in use, the water that needs to be deionized enters the EDI body 1 from the water inlet, and then after deionization, the ultrapure water is discharged from the pure water outlet, and the concentrated brine is discharged from the concentrated water opening. However, when the resin layer is partially scaled and lumped, the water pressure around the scaling block will increase, so the sealing plate 19 and the auxiliary movable plate 7 close to the scaling block will be separated due to the water pressure (because in the initial setting, the tension of the second tension spring 36 is equal to the normal water pressure, so when the local water pressure increases, water will enter the crushing block 9, thereby causing the crushing block 9 to separate from the auxiliary movable plate 7, and at the same time, the water pressure when the water enters the crushing block 9 acts on the sealing drive hemispherical cover 23), so when the two crushing blocks 9 are close to each other, the scaled resin will be broken apart, thereby enabling the water to flow normally.

[0053] When the water pressure acts on the sealing driving hemispherical cover 23, it will cause the crushing block 9 to move away from the auxiliary movable plate 7, and at the same time, it will cause the sealing plate 19 to tilt (because the first cross partition plate 15, the second cross partition plate 17 and the sealing driving hemispherical cover 23 can evenly divide the space of the pressure groove near the auxiliary movable plate 7 into four separate closed spaces, so the water entering the four separate closed spaces also enters from four different directions, so when the water enters the crushing block 9, there must be a separate closed space closest to the scaling block, so this separate closed space is the most closed space of the scale block. The water pressure in the enclosed space must be the greatest, so when the water pressure causes the crushing block 9 to separate from the auxiliary movable plate 7, it will also cause the sealing driving hemispherical cover 23 to tilt with the sealing plate 19, and the positions of the four separate enclosed spaces are exactly at the angle between each two adjacent connecting parts. Therefore, when the sealing plate 19 tilts, it will tilt with the auxiliary sealing cylinder 20. At the same time, when one end of the auxiliary sealing cylinder 20 tilts, the other end will tilt up. Therefore, the auxiliary sealing cylinder 20 will cut off the two first connecting grooves 31 on the tilted end (in the auxiliary sealing cylinder 20). When the auxiliary sealing cylinder 20 is in the initial position, the auxiliary sealing cylinder 20 has cut off half of the first connecting groove 31, so when the driving groove 24 is not yet connected to the limit card channel, the auxiliary sealing cylinder 20 has cut off the first connecting groove 31, and when the sealing plate 19 continues to tilt, the auxiliary sealing cylinder 20 will continue to rotate in the crushing block 9), so when the water pressure on the driving groove 24 continues to increase, the tilt angle of the sealing plate 19 will become larger and larger, and finally the driving groove 24 will be connected to the limit card channel, so that the liquid will pass through the auxiliary driving cylinder 21 and enter the sealing plate 19 is in the pressure groove on the side away from the auxiliary movable plate 7 (wherein the liquid passes through the auxiliary driving cylinder 21 from the cross channel 25), and finally enters the crushing barrel 10 through the annular channel 26, the first connecting groove 31, the first connecting channel 14 and the second connecting channel 22 in sequence, so that when the two crushing barrels 10 at the upper end away from the sealing plate 19 are subjected to water pressure, the two crushing blocks 9 can be caused to move relative to each other and move in a direction close to each other, so that the scaling blocks can be crushed more accurately and delicately, so that the water flow can be caused to flow better.

[0054] After the scaling block is broken, the water pressure around it will be restored. Therefore, through the setting of the first spring 30, the sealing plate 19 can be pulled back to the initial position. At the same time, through the setting of the second tension spring 36, the second cross partition plate 17 can be pulled back to the initial position. At this time, the water pressure in the crushing barrel 10 will flow out of the crushing block 9 from the pressure relief port, thereby prompting the crushing block 9 to completely restore to the initial position with the auxiliary movable plate 7. When the crushing block 9 and the auxiliary movable plate 7 are in conflict with each other, the blocking block 27 will not block the pressure relief port. At this time, the pressure relief port is connected to the crushing block 9, but when the crushing block 9 moves in a direction away from the auxiliary movable plate 7, the blocking block 27 will block the pressure relief port. Therefore, the liquid entering the pressure tank will not flow out from its pressure relief port.
