Description

Technical Field

[0001] This invention relates to the field of electrodeionized ultrapure water technology, and in particular to an electrodeionized ultrapure water device with a water shortage protection function. Background Technology

[0002] Electrodeionization (EDI) is a pure water preparation method that integrates ion exchange, ion exchange membranes, and ion electromigration. Its core principle is the organic combination of electrodialysis and ion exchange technologies. A DC electric field at both ends of the device drives the directional movement of charged ions in the water. Simultaneously, the selective permeability of anion exchange membranes (anion membranes) and cation exchange membranes (cation membranes) to anions and cations, along with the adsorption and exchange of ions by ion exchange resins, accelerates ion migration and separation, ultimately achieving deep water purification. This technology, with its advanced process design, simple operation, and outstanding environmental advantages, is hailed as a "green innovation" in the field of pure water preparation and is currently widely used in pure and ultrapure water preparation scenarios in numerous industries, including power, semiconductors, chemicals, and shipbuilding.

[0003] Chinese patent CN212504154U discloses an EDI membrane stack with an anode, a cathode, and an electrode water channel. An equal number of cation and anion membranes are alternately arranged between the anode and cathode to form alternating concentrate and desalination chambers. The anode and its adjacent cation membrane constitute the anode water chamber, and the cathode and its adjacent anion membrane constitute the cathode water chamber. The anode and cathode water chambers are located within the anode and cathode partitions, respectively. The electrode water channel guides the electrode water through the cathode and anode water chambers. The ion content in the anode and cathode water chambers of this invention is significantly lower than that in traditional membrane stacks, effectively suppressing chlorine generation. When the electrode water is reused in the reverse osmosis system, its strong oxidizing properties are weakened, thus reducing the amount of chemicals required for reverse osmosis. This invention also discloses the application of the membrane stack in electrode water circulation and concentrate reuse, achieving chlorine-free electrode water generation and improving concentrate reuse efficiency and overall water production rate of the water treatment system.

[0004] Although the above technical solutions can improve the overall water production rate, during use, due to internal blockage, the internal membrane stack or resin layer is prone to water shortage or flow interruption, which leads to a sharp increase in local temperature under the action of electric field, and then causes dry burning failures such as resin carbonization and membrane damage.

[0005] Therefore, it is necessary to invent an electro-deionized ultrapure water device with water shortage protection to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an electro-deionized ultrapure water device with a water shortage protection function to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an electro-deionized ultrapure water device with water shortage protection function, comprising multiple membrane stack units arranged in a linear array between a cathode plate and an anode plate; each membrane stack unit comprises an anion membrane, a concentrate separator, a cation membrane, and a desalination separator arranged sequentially from the cathode to the anode; each concentrate separator and each desalination separator is provided with a through-slot, a raw water inlet, a first concentrate inlet, a first concentrate outlet, a second concentrate inlet, a second concentrate outlet, a first desalination inlet, a first desalination outlet, and a second desalination outlet; the through-slot is provided with ion exchange resin.

The top storage tank inside the freshwater baffle is connected to the first freshwater inlet, and the bottom storage tank inside the freshwater baffle is connected to the second freshwater outlet. The top storage tank inside the concentrated water baffle is connected to the second concentrated water inlet, and the bottom storage tank inside the concentrated water baffle is connected to the second concentrated water outlet.

[0010] Trapezoidal groove, used to connect the storage groove and the through groove;

[0011] An adjusting component, placed inside the receiving groove, is used to adjust the flow between the receiving groove and the trapezoidal groove, and can also prevent resin from flowing back into the receiving groove.

[0012] A clamping component, which is detachably connected to the storage groove, is used to press the adjusting component against the inner wall of the trapezoidal groove;

[0013] The elastic bimetallic temperature sensing element has one end connected to the adjusting component and the other end rotatably connected to a pressure ring threaded to the clamping component. It responds to temperature changes and drives the adjusting component to adjust the opening and closing of the receiving groove and the trapezoidal groove.

[0014] A sealing component, threadedly connected to a pressure ring, is used to seal the pressure ring.

[0015] Preferably, the adjusting member includes two symmetrically arranged vertical parts, the tops of which abut against the pressing member; a first flat plate part, the two ends of which are respectively connected to the bottom of the two vertical parts through hook-shaped connecting parts, and a first flow channel is formed on its surface;

[0016] Two elastic deformation parts are arranged symmetrically, and one end is connected to the top side wall of the vertical part. Their elastic force is less than that of the elastic bimetallic temperature sensing element.

[0017] The second flat plate portion is connected to the other end of the elastically deformable portion through the first connecting portion, and its surface is provided with a second flow channel that is offset from the first flow channel;

[0018] The through tube passes through the first plate portion and the second plate portion. It is fixedly connected to the second plate portion and slidably connected to the first plate portion. Its top is slidably placed in the clamping member and connected to the elastic bimetallic temperature sensing element. Its bottom extends into the through groove, which can sample the resin.

[0019] Preferably, it also includes an alarm system for sounding an alarm; and a temperature monitoring system for real-time monitoring of the equipment temperature;

[0020] A flow detection system is used to monitor the flow rate in the freshwater pipe connected to the first freshwater inlet and the flow rate in the concentrate pipe connected to the second concentrate inlet.

[0021] When the flow rate in the freshwater pipe connected to the first freshwater inlet and the flow rate in the concentrated water pipe connected to the second concentrated water inlet are both greater than zero, and the temperature monitoring system detects that the equipment temperature is greater than the preset value, the control equipment stops working, the alarm system issues an alarm for "the water shortage protection component is working normally, but the equipment temperature is still too high".

[0022] Preferably, when the flow rate in the freshwater pipe connected to the first freshwater inlet and the flow rate in the concentrated water pipe connected to the second concentrated water inlet are both zero, and the temperature monitoring system detects that the equipment temperature is greater than the preset value, the control equipment stops working, and the alarm system issues an alarm for "the equipment temperature is too high due to the failure of the water shortage protection component".

[0023] Preferably, the clamping member is T-shaped and is detachably connected to the storage groove. One end of the member near the trapezoidal groove is provided with a pushing part of the pushing adjustment member.

[0024] Preferably, the top and bottom of the through groove are provided with water distribution component receiving grooves; a water distribution component is snapped into the water distribution component receiving groove.

This invention, through the cooperation of the raw water inlet, the first concentrated water inlet, the first concentrated water outlet, the second concentrated water inlet, the second concentrated water outlet, the first fresh water inlet, the first fresh water outlet, the second fresh water outlet, and the water shortage protection component, can replenish water to the interior through the first fresh water inlet and the second concentrated water inlet, thereby preventing the water distribution component from being blocked and causing dry burning.

[0029] 2. This invention utilizes the cooperation between the raw water inlet, the first concentrated water inlet, the first concentrated water outlet, the second concentrated water inlet, the second concentrated water outlet, the first fresh water inlet, the first fresh water outlet, the second fresh water outlet, and the water shortage protection component. When it is necessary to sample and test the resin, the equipment is first stopped, then the sealing parts are removed, and the sampling tube is inserted into the through-tube to sample the resin in the through-groove, thus facilitating the sampling of the internal resin.

[0030] 3. The present invention achieves the interception of fluid between the raw water inlet, the first concentrated water inlet, the first concentrated water outlet, the second concentrated water inlet, the second concentrated water outlet, the first fresh water inlet, the first fresh water outlet, the second fresh water outlet, and the water shortage protection component through the mutual cooperation between the raw water inlet, the first concentrated water inlet, the first fresh water outlet, the second fresh water outlet, and the water shortage protection component.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] This invention provides, for example Figures 1 to 11 The illustrated electro-deionized ultrapure water device with water shortage protection function includes multiple membrane stack units arranged in a linear array between cathode plate 1 and anode plate 2.

[0045] The membrane stack unit includes an anion membrane 3, a concentrate baffle 4, a cation membrane 5, and a desalination baffle 6 arranged sequentially from the cathode to the anode. Both the concentrate baffle 4 and the desalination baffle 6 are provided with a through-slot 7, a raw water inlet 8, a first concentrate inlet 9, a first concentrate outlet 10, a second concentrate inlet 11, a second concentrate outlet 12, a first desalination inlet 13, a first desalination outlet 14, and a second desalination outlet 15. The through-slot 7 is provided with ion exchange resin.

[0046] The through groove 7 of the concentrate baffle 4 forms a concentrate chamber between the anion membrane 3 and the cation membrane 5, and the through groove 7 of the desalination baffle 6 forms a desalination chamber between the anion membrane 3 and the cation membrane 5.

[0047] It also includes a water shortage protection component 17, which is disposed at the top and bottom of the concentrate baffle 4 and the desalination baffle 6.

[0048] The water shortage protection component 17 includes a receiving groove 171. The top receiving groove 171 inside the freshwater baffle 6 is connected to the first freshwater inlet 13, the bottom receiving groove 171 inside the freshwater baffle 6 is connected to the second freshwater outlet 15, the top receiving groove 171 inside the concentrated water baffle 4 is connected to the second concentrated water inlet 11, and the bottom receiving groove 171 inside the concentrated water baffle 4 is connected to the second concentrated water outlet 12. This invention can replenish water to the inside through the first freshwater inlet 13 and the second concentrated water inlet 11 after the water distribution component 19 is blocked, thereby preventing the water distribution component 19 from being blocked and causing dry burning.

[0049] The trapezoidal groove 172 is used to connect the receiving groove 171 and the through groove 7. By setting the trapezoidal groove 172, the present invention can, on the one hand, guide the water in the first fresh water inlet 13 and the second concentrated water inlet 11 into the receiving groove 171, and on the other hand, support the adjusting member 173 to prevent the adjusting member 173 from entering the through groove 7.

[0050] Adjusting element 173, which is placed in the receiving groove 171, is used to adjust the flow between the receiving groove 171 and the trapezoidal groove 172, and can also prevent resin from flowing back into the receiving groove 171.

[0051] The clamping member 174 is detachably connected to the storage groove 171 and is used to press the adjusting member 173 against the inner wall of the trapezoidal groove 172. By setting the clamping member 174, the present invention avoids the situation where resin enters the storage groove 171 due to the overall movement of the adjusting member 173 during the adjustment process.

[0052] The elastic bimetallic temperature sensing element 175 has one end connected to the adjusting member 173 and the other end rotatably connected to a pressure ring 176 threadedly connected to the clamping member 174. It deforms in response to temperature changes and moves the adjusting member 173 to adjust the opening and closing of the receiving groove 171 and the trapezoidal groove 172. By setting the elastic bimetallic temperature sensing element 175, when the equipment temperature rises, the elastic bimetallic temperature sensing element 175 deforms, which will move the adjusting member 173 to connect the receiving groove 171 and the trapezoidal groove 172, thereby replenishing liquid into the through groove 7 and cooling it down, thus avoiding dry burning.

[0053] Specifically, the elastic bimetallic temperature sensing element 175 is an elastic bimetallic spring, which is existing technology and will not be described in detail here.

[0054] The sealing element 177 is threadedly connected to the pressure ring 176 and is used to seal the pressure ring 176. By setting the sealing element 177, the present invention makes it easy to sample the internal resin using the clamping element 174 after the sealing element 177 is removed.

[0055] Furthermore, the adjusting member 173 includes two symmetrically arranged vertical portions 1731, the tops of which abut against the clamping member 174; the present invention achieves the fixation of the adjusting member 173 by providing the vertical portions 1731, which cooperate with the clamping member 174.

[0056] The first flat plate portion 1732 has two ends connected to the bottom of two vertical portions 1731 via hook-shaped connecting portions 1733, and a first flow channel 1734 is provided on its surface.

[0057] Two elastic deformation parts 1735 are symmetrically arranged, with one end connected to the top sidewall of the vertical part 1731. Their elastic force is less than that of the elastic bimetallic temperature sensing element 175. The elastic bimetallic temperature sensing element 175 is specifically an elastic bimetallic temperature sensing spring.

[0058] The second flat plate portion 1736 is connected to the other end of the elastic deformation portion 1735 via the first connecting portion 1737, and its surface is provided with a second flow channel 1738 that is misaligned with the first flow channel 1734. This invention, by setting a first flat plate portion 1732 and a second flat plate portion 1736, allows the first flat plate portion 1732 to be pressed onto the second flat plate portion 1736 under the elastic force of the elastic deformation portion 1735. Due to the staggered distribution of the first flow channel 1734 and the second flow channel 1738, the fluid between the receiving tank 171 and the trapezoidal tank 172 is intercepted, while preventing resin backflow. When the temperature rises due to water shortage inside the equipment, the elastic bimetallic temperature sensing element 175 will deform under the influence of temperature. Under the deformation of the elastic bimetallic temperature sensing element 175, the through pipe 1739 and the first flat plate portion 1732 will be pulled upward, restoring the fluid from the receiving tank 171 into the trapezoidal tank 172, thereby replenishing the liquid, preventing dry burning, and achieving water shortage protection.

[0059] The through-tube 1739 passes through the first flat plate portion 1732 and the second flat plate portion 1736. It is fixedly connected to the second flat plate portion 1736 and slidably connected to the first flat plate portion 1732. Its top is slidably placed in the clamping member 174 and connected to the elastic bimetallic temperature sensing element 175. Its bottom extends into the through-groove 7, which can sample the resin. By setting the through-tube 1739, the present invention can, on the one hand, cooperate with the elastic bimetallic temperature sensing element 175 to adjust the opening and closing of the receiving groove 171 and the trapezoidal groove 172. On the other hand, by removing the sealing member 177 and inserting the sampling tube into the through-tube 1739, the internal resin can be sampled.

[0060] It also includes an alarm system for sounding an alarm.

[0061] A temperature monitoring system is used to monitor the temperature of equipment in real time.

[0062] The flow detection system is used to monitor the flow rate in the freshwater pipe connected to the first freshwater inlet 13 and the flow rate in the concentrate pipe connected to the second concentrate inlet 11.

[0063] Specifically, the flow detection system includes a first flow sensor, which is placed inside a freshwater pipe connected to the first freshwater inlet 13, and is used to monitor the flow rate inside the freshwater pipe connected to the first freshwater inlet 13.

[0064] The second flow sensor is placed inside the concentrate pipe connected to the second concentrate inlet 11, and is used to monitor the flow rate inside the concentrate pipe connected to the second concentrate inlet 11.

[0065] The control system is electrically connected to the alarm system, temperature monitoring system, and flow detection system.

[0066] Specifically, the clamping member 174 is T-shaped and is detachably connected to the storage groove 171. One end of it near the trapezoidal groove 172 is provided with a pushing part 1741 of the pushing adjustment member 173. The inside of the pushing member 1741 is provided with a through groove that matches the through tube 1739. The end of the pushing member 1741 away from the trapezoidal groove 172 is provided with a threaded groove that matches the pressure ring 176.

[0067] The top and bottom of the through groove 7 are provided with water distribution component receiving grooves 18; water distribution component 19 is snapped into the water distribution component receiving groove 18; by setting the water distribution component 19, the present invention is used to guide the water flow evenly into the through groove 7 to prevent local water shortage and dry burning.

[0068] The water distribution container 18 at the top of the concentrate baffle 4 is connected to the first concentrate inlet 9; when the equipment is working normally, the concentrate enters the concentrate chamber through the first concentrate inlet 9 and the water distribution container 18.

[0069] The water distribution container 18 at the bottom of the concentrate baffle 4 is connected to the first concentrate outlet 10. When the equipment is working normally, the concentrate flows out through the concentrate chamber, the water distribution container 18 and the first concentrate outlet 10.

[0070] The water distribution container 18 at the top of the freshwater baffle 6 is connected to the raw water inlet 8; when the equipment is working normally, the raw water enters the freshwater chamber through the raw water inlet 8 and the water distribution container 18.

[0071] The water distribution container 18 at the bottom of the freshwater baffle 6 is connected to the first freshwater outlet 14; when the equipment is working normally, freshwater flows out through the freshwater chamber, the water distribution container 18 and the first freshwater outlet 14.

[0072] During operation, raw water enters the fresh water chamber through the raw water inlet 8 and the water distribution container 18. The fresh water in the fresh water chamber flows out through the bottom water distribution container 18 and the first fresh water outlet 14. Concentrated water enters the concentrated water chamber through the first concentrated water inlet 9 and the water distribution container 18. The concentrated water in the concentrated water chamber flows out through the bottom water distribution container 18 and the first concentrated water outlet 10.

[0073] When the equipment is short of water, the local temperature rises sharply under the action of the electric field. When the temperature rises, the elastic bimetallic temperature sensing element 175 is affected by the temperature and deforms. Under the action of the deformation of the elastic bimetallic temperature sensing element 175, the through pipe 1739 and the second plate part 1736 are pulled upward. The upward movement of the second plate part 1736 will connect the first flow channel 1734 and the second flow channel 1738. The connection between the first flow channel 1734 and the second flow channel 1738 will allow the fresh water in the first fresh water inlet 13 to enter the fresh water chamber through the receiving tank 171, the first flow channel 1734, the second flow channel 1738 and the trapezoidal groove 172. Similarly, the concentrated water in the second concentrated water inlet 11 will enter the concentrated water chamber through the receiving tank 171, the first flow channel 1734, the second flow channel 1738 and the trapezoidal groove 172, thus ultimately achieving the prevention of dry burning.

[0074] When it is necessary to sample and test the resin, first stop the equipment, then remove the sealing part 177, insert the sampling tube into the through tube 1739, and then insert it into the through groove 7 to sample the resin in the through groove 7. Based on the resin test results, determine whether the resin needs to be replaced.

[0075] During equipment operation, when the flow rate detected by the flow detection system in both the freshwater pipe connected to the first freshwater inlet 13 and the concentrated water pipe connected to the second concentrated water inlet 11 is greater than zero, and the temperature monitoring system detects that the equipment temperature is greater than a preset value (which is greater than the deformation termination temperature of the elastic bimetallic temperature sensing element 175), the equipment will stop operating, and the alarm system will issue a "Water shortage protection component 17 is working normally, but the equipment temperature is still too high" alarm. At this time, since the flow rate is greater than zero, it indicates that the water shortage protection component 17 has started working, replenishing water to the equipment. However, the temperature monitoring system detects that the equipment temperature is still greater than the preset value, indicating that the water shortage protection component 17 cannot regulate the internal temperature of the equipment. Therefore, a shutdown alarm is triggered, and the equipment is shut down for maintenance to prevent further dry burning, thus achieving protection.

[0076] During equipment operation, when the flow rate detected by the flow detection system in the freshwater pipe connected to the first freshwater inlet 13 and the flow rate detected by the second concentrated water inlet 11 in the concentrated water pipe are both zero, and the temperature monitoring system detects that the equipment temperature is higher than the preset value, the equipment is controlled to stop working, and the alarm system issues an alarm for "water shortage protection component 17 failure causing equipment temperature to be too high". At this time, since the flow rate is zero, it indicates that the water shortage protection component 17 has not started working. The temperature monitoring system detects that the equipment temperature is higher than the preset value, indicating that the temperature monitoring system has detected that the equipment temperature is already higher than the preset value, and the water shortage protection component 17 still has not started working, indicating that the water shortage protection component 17 is faulty, requiring an alarm and shutdown for maintenance to prevent further dry burning. Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
