Description

Technical Field

[0001] The present invention relates to the technical field of water treatment devices, in particular to a resin adsorption tank for water treatment. Background Art

[0002] Ion exchange resin water purification is a traditional water purification technology. The raw water is pumped into anion and cation exchange resin columns or resin adsorption tanks through a water supply pump. After the impurities are adsorbed by the anion and cation exchange resins, the water is purified.

[0003] A Chinese patent with authorization announcement number CN211733904U discloses a resin adsorption tank for water treatment, including a cylinder, one end of which is detachably connected to an upper head and the other end of which is detachably connected to a lower head, the upper head having a water outlet and the lower head having a water inlet; the connection between the upper head and the cylinder, and the connection between the lower head and the cylinder are both provided with a flower plate assembly located inside the cylinder; a resin filling area for filling with adsorption resin is formed between the two flower plate assemblies, a resin filling port and a resin discharge port are provided at both ends of the cylinder, and valves are provided, so that the resin can be easily replaced without disassembling the tube body.

[0004] In existing resin adsorption tanks, the sterilization function of water is achieved through ion exchange within the resin. However, as the total amount of water treated increases, the effective sterilization ions in the resin gradually decrease. However, to achieve a better sterilization effect, a certain concentration of sterilization ions is required in the water. When the iodine ions in the resin do not meet this requirement, it often needs to be replaced, resulting in a certain amount of resource waste.

[0005] Secondly, the concentration of effective ions released from the resin is insufficient, which may be due to dust and bacterial film adhering to the surface, making it difficult to release the effective ions in the resin. In the existing technology, water backwashing is used to remove dust from the resin surface, but the efficiency of this method is often relatively low.

[0006] To this end, the present invention proposes a resin adsorption tank for water treatment to solve the above problems. Summary of the Invention

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0058] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0059] like Figures 1-14 As shown;

[0060] A resin adsorption tank for water treatment, comprising:

[0061] like Figure 1-Figure 3 As shown, the tank body 1 has a split structure. The tank body 1 includes an upper tank body 11 and a lower tank body. A positioning member 2 is stretched at the connection between the upper tank body 11 and the lower tank body. The positioning member 2 includes two L-shaped plates 21 and a telescopic plate 23 fixed between the two L-shaped plates 21. The two L-shaped plates 21 are pressed against the connection between the upper tank body 11 and the lower tank body through the telescopic plate 23.

[0062] Among them, a lower extension plate 18 and an upper extension plate 19 are respectively provided at the connection between the upper tank body 11 and the lower tank body. The lower extension plate 18 is welded to the end of the lower tank body, and a plurality of positioning rods are extended from the upper and lower end faces of the lower extension plate 18. The upper extension plate 19 is welded to the end of the upper tank body 11, and a plurality of circular holes for the positioning rods to pass through are opened on the surface of the upper extension plate 19. The positioning of the upper tank body 11 and the lower tank body is achieved by the plug-in connection of the lower extension plate 18 and the upper extension plate 19.

[0063] Among them, the positioning member 2 includes two L-shaped plates 21 and a telescopic plate 23 fixed between the two L-shaped plates 21. Positioning holes 22 for the positioning rod to pass through are provided on the surfaces of the two L-shaped plates 21. By stretching the positioning member 2, it is sleeved on the surfaces of the lower extension plate 18 and the upper extension plate 19. The positioning member 2 is squeezed by the lower extension plate 18 and the upper extension plate 19, causing the telescopic plate 23 to be stretched. The elastic force generated by the stretching of the telescopic plate 23 causes the two L-shaped plates 21 to be pressed on the surfaces of the lower extension plate 18 and the upper extension plate 19, thereby realizing a tight connection between the lower extension plate 18 and the upper extension plate 19, the upper tank body 11 and the lower tank body. The detachable connection method facilitates the cleaning of the tank body 1, and also facilitates the removal of the components in the inner cavity of the tank body 1, which facilitates a series of tasks such as maintenance, replacement and cleaning.

[0064] In one embodiment, a plurality of openings are provided on the surface of the tank body 1, which are respectively a water inlet 14, a water outlet 15, an inlet 16 and a outlet 17. Sewage enters the inner cavity of the tank body 1 from the water inlet 14, forming an upward water flow and flowing out through the water outlet 15. Clean water or regeneration liquid enters the inner cavity of the tank body 1 from the inlet 16, forming a downward water flow and flowing out to the outlet 17. A ball valve for throttling is configured at each opening position. By blocking different openings with the ball valve, intermittent alternation of the sewage treatment mode and the cleaning and regeneration mode is achieved, so as to achieve regular regeneration of the iodine resin and improve the sterilization efficiency of the sewage.

[0065] Among them, the lower tank body includes a middle ring body 12 and a bottom tank body 13 connected in an integral manner, the water inlet 14 is arranged on the cylindrical wall of the middle ring body 12, the water outlet 15 and the inlet 16 are both arranged on the upper tank body 11, and the outlet 17 is opened at the bottom end of the bottom tank body 13 for discharging liquid, and the inlet 16 and the outlet 17 are opposite to each other, and the water inlet 14, the water outlet 15, the inlet 16 and the outlet 17 are all connected to the inner cavity of the tank body 1.

[0066] Reference Figure 6 、 Figure 7 as well as Figure 8 As shown, the resin adsorption tank for water treatment also includes a sterilization module 4, which is arranged in the middle of the inner cavity of the tank body 1. The sterilization module 4 includes a cylinder 41 with multiple coaxial annular chambers. The multiple coaxial annular chambers do not interfere with each other and form independent chambers. The multiple annular chambers are respectively named as the primary cavity, the secondary cavity, the tertiary cavity and the quaternary cavity. The cylinder 41 includes multiple coaxial annular sheets 411 with different diameters and multiple arc-shaped blocks 42. The arc-shaped blocks 42 are welded to the inner wall of the annular sheet 411. The annular sheet 411 is a split structure. Figure 7 As shown, the entire cylinder 41 is spliced ​​together by two left and right parts, and the left and right parts are symmetrical. A connecting plate is provided at the bottom end of the multiple annular sheets 411, and the multiple annular sheets 411 are connected by the connecting plate. A plurality of sets of parallel tight hoops 46 are fixed to the outer surface of an outer annular sheet 411. The tight hoops 46 are squeezed and connected as a whole by the middle ring body 12. After being tightened by the tight hoops 46, the components of the split annular sheets 411 are more tightly connected. The outer diameter of the tight hoop 46 is consistent with the inner diameter of the middle ring body 12, and the inner diameter of the tight hoop 46 is consistent with the outer diameter of the cylinder 41.

[0067] The interior of the cylinder 41 is provided with multiple groups of parallel baffle groups 44, and the slits between multiple coaxial annular plates 411 with different diameters are sealed by multiple groups of baffle groups 44. Each group of baffle groups 44 includes multiple coaxial annular baffles located in the annular chamber. The multiple annular baffles are located in the same horizontal plane. An annular baffle is spliced ​​by a left plate baffle and a right plate baffle. The left plate baffle or the right plate baffle is extended into the clamping gap of the arc-shaped block 42 and rotated to the inside of the cylinder 41, and then another right plate baffle or left plate baffle is installed. Finally, the other annular baffles are installed in sequence according to the above method to realize the assembly of the baffle group 44.

[0068] Reference Figure 7 and Figure 8 As shown, multiple annular baffles in a baffle group 44 are located on the same horizontal plane and are clamped by an arc-shaped baffle 42 fixed to the annular sheet 411. Each annular chamber is divided into multiple chambers by the annular baffles, wherein the annular baffles in the several baffle groups 44 located at the bottom are arranged as screens, and there are five baffle groups 44. The annular baffles in the baffle group 44 located at the top are composed of annular plates, forming five small chambers from bottom to top. Water flows into each annular chamber through the pipe of the bottom tank body 13, passes through the five small chambers in turn, and is then discharged through the annular baffles at the top. Iodine resin is placed in the three small chambers in the middle of each annular chamber, and the annular baffles arranged in the form of a screen block the iodine resin to prevent it from flowing out through the water body.

[0069] The sterilization module 4 also includes a pipeline. Three groups of circular plates are provided at the center of the cylinder 41. The three groups of circular plates are respectively a sieve plate 47, a circular sealing plate 48 and a positioning plate 49 from bottom to top. The sieve plate 47 and the circular sealing plate 48 form a liquid storage cavity. The liquid storage cavity is connected to the annular cavity through a pipeline and extends into the annular cavity. There are multiple pipelines, which are inserted from the inside to the outside of different annular cavities, so that each annular cavity is separately connected to the center of the cylinder 41. The annular cavity passes through the top of the cylinder 41 to form a plurality of diversion holes. The diversion holes are opened on a group of annular baffles at the top. The port where the pipeline passes through the annular cavity is sealed with a magnetic suction valve 43.

[0070] A support module 6 is welded to the inner wall of the tank body 1. The support module 6 includes a baffle 61 for supporting the cylinder body 41 and a plurality of scrapers 62 inserted into the baffle 61.

[0071] The sieve plate 47, the circular sealing plate 48, and the positioning plate 49 also have a left-right split structure, and the left and right parts are symmetrical. A plurality of sieve holes are provided on the surface of the sieve plate 47. When the sieve plate 47 is rotated by an external force, the scraper 62 scrapes the surface of the sieve plate 47 to clean the sieve plate 47. A plurality of positioning holes 22 are provided on the surface of the positioning plate 49. The sieve plate 47, the circular sealing plate 48, and the positioning plate 49 are all integrally connected to the cylinder 41. Multiple pipes are clamped in the area clamped by the sieve plate 47 and the circular sealing plate 48, so that a water inlet area is formed between the sieve plate 47 and the circular sealing plate 48. The water entering from the bottom of the tank body 1 is initially sieved through the sieve plate 47 and enters the water inlet area, and then enters different annular chambers through the pipes. A sealed area is formed between the circular sealing plate 48 and the positioning plate 49 to prevent water from the water inlet area from seeping upward.

[0072] The magnetic valve 43 includes a left sealing member 431 and a right sealing member 432. The left sealing member 431 includes a left sealing plate and a plurality of round rods. The left sealing plate is fixed to the surface wall of the annular piece 411 through the plurality of round rods. The right sealing member 432 includes a right sealing plate and a telescopic thin rod. The right sealing plate is fixed to the surface wall of the annular piece 411 through the telescopic thin rod and pressed on the left sealing member. The left sealing member 431 and the right sealing member 432 are respectively located on both sides of the annular piece 411; an electromagnet is provided inside the left sealing member, and the right sealing member is set as a magnet stone. The same magnetism as the right sealing plate is generated, so that the telescopic thin rod is extended. When the pipe from the water inlet area to the primary cavity is not blocked, when the iodine ions inside the primary cavity are exhausted, or the remaining iodine ions are not enough to kill the iodine ions in the sewage, it is necessary to open the diversion hole to the secondary cavity. In order to prevent the sewage from flowing out directly from the primary cavity, not flowing out from the secondary cavity or less water flowing through the secondary cavity, a pipe is provided from the water inlet area directly to the secondary cavity, the tertiary cavity and the quaternary cavity, and the magnetic suction valve 43 is provided at the pipe mouth.

[0073] The surface of the right sealing plate is concave to form a circular cavity 433, which is used to increase the area where sewage acts.

[0074] If the iodine ions released by the iodine resin in the primary cavity are small, the diversion holes leading to the primary cavity, the tertiary cavity and the quaternary cavity are all blocked, and the diversion hole leading to the secondary cavity is opened;

[0075] If the iodine ions released by the iodine resin in the secondary cavity are small, the diversion holes leading to the primary cavity, the secondary cavity and the quaternary cavity are all blocked, and the diversion hole leading to the tertiary cavity is opened;

[0076] If the iodine ions released by the iodine resin inside the tertiary cavity are small, the diversion holes leading to the primary cavity, the secondary cavity and the tertiary cavity are all blocked, and the diversion hole leading to the quaternary cavity is opened;

[0077] If the iodine ions released by the iodine resin inside the quaternary cavity are small, the diversion holes leading to the primary cavity, the secondary cavity, the tertiary cavity and the quaternary cavity are all blocked, and the sewage cannot flow.

[0078] The purpose of this design is to utilize a narrower flow channel so that fewer iodine ions can produce a longer action length, thereby increasing the effectiveness of the iodine ion action time.

[0079] Secondly, the device divides the annular chamber into multiple small chambers. Since water flows directly into the upper and lower chambers, resins are placed in the three small chambers in the middle of the annular chamber to avoid dispersing the iodine resin and reduce the area of ​​iodine resin acting on the sewage. Different resins can be selected according to the source of the sewage. For example, strong acid cation exchange resins are mainly used to soften hard water, that is, to remove divalent cations such as calcium and magnesium, and are suitable for water softening, such as industrial cooling water systems and boiler feed water treatment. For example, weak acid cation exchange resins are generally used to remove weaker cations in water, such as ammonia ions, and are suitable for deammoniation and wastewater treatment. For example, strong basic anion exchange resins can remove various anions in water, especially chloride ions and sulfate ions, and are widely used in pure water preparation, wastewater treatment and other fields. For example, weak basic anion exchange resins are mainly used to remove weak acid anions such as bicarbonate ions, and are suitable for removing carbon dioxide from water or performing fine treatment after softening water. There are also various types of resins, such as adsorption resins, which mainly use iodine ions as an example.

[0080] By placing different types of resins in different chambers, targeted treatment of different types of sewage pollution can be achieved;

[0081] Resins of different contents can also be placed in the three small chambers in the middle of the annular chamber. For example, the iodine resin used before, but the iodine ion concentration contained in the iodine resin is not enough for sterilization, the iodine ions can be used as supplementary resin and re-entered into the sewage to achieve the reuse of the resin on the sewage, saving resources while improving the utilization efficiency of the iodine resin.

[0082] In one embodiment, the cleaning and regeneration module 3 is arranged at the top of the inner cavity of the tank body 1. The cleaning and regeneration module 3 includes a liquid storage tank 31 and a plurality of steel pipes 32. The surface of the liquid storage tank 31 is provided with a liquid inlet and a liquid outlet. The liquid inlet on the surface of the liquid storage tank 31 is connected to an external pipeline, and a pressure pump is configured on the pipeline. The pressure pump is used to pressurize the external fluid to impact the liquid storage tank 31 to form high-pressure water. The plurality of steel pipes 32 are connected to the liquid outlet on the surface of the liquid storage tank 31. The plurality of steel pipes 32 are inserted into the annular chamber, and a circular plate pressure ring 33 is fixed on the surface of the steel pipe 32. The circular plate pressure ring 33 is press-fitted onto the cylinder 41 so that the cylinder 41 does not move upward due to the upward water flow, and the top surface of the circular plate pressure ring 33 is convex downward, which reduces the contact area between the circular plate pressure ring 33 and the cylinder 41. A plurality of closely arranged small openings are opened on the surface of the steel pipe 32, so that the high-pressure water in the liquid storage tank 31 passes through the steel pipe 32 into the annular chamber and is ejected at high pressure through the tight small openings on the surface of the steel pipe 32. The high-pressure water impacts and cleans the resin, so that the resin recovers its sterilization ability. A plurality of supporting annular plates are installed at the liquid inlet end of the liquid storage tank 31;

[0083] A plurality of rotating plates 162 and supporting plates 161 are provided at the top opening of the tank body 1. The rotating plates 162 rotate and fit onto the upper surface of the supporting plates 161, and the supporting plates 161 support the liquid storage tank 31 through the rotating plates 162. A plurality of supporting annular plates are pressed on the rotating plates 162 to realize the lifting of the liquid storage tank 31. The rotating setting of the rotating plates 162 facilitates the end of the liquid storage tank 31 to pass upward from the upper tank body 11.

[0084] When the concentration of ions released by the resin is low, it may be that the ion concentration in the resin gradually decreases with the release, or it may be due to impurities and microbial films on the surface of the iodine resin. The adsorption capacity of the resin is improved, and the resin is treated to avoid adhering impurities and microbial films. The regeneration liquid is then sent into the annular chamber through the steel pipe 32, so that the resin receives the regeneration liquid to achieve regeneration, and the intermittent alternation of the sewage treatment mode and the cleaning and regeneration module 3 is achieved to improve the sterilization efficiency of the sewage.

[0085] When cleaning the regeneration module 3 , the magnetic valves 43 on all pipelines are closed, so that the regeneration liquid exists only in each annular chamber, which reduces the required amount of regeneration liquid and prevents excessive waste of the regeneration liquid.

[0086] In one embodiment, a rotating module 5 is provided at the bottom end of the inner cavity of the tank body 1 and inserted into the center of the cylinder 41 to drive the cylinder 41 to rotate in the inner cavity of the tank body 1; the rotating module 5 includes an annular inner frame, a driving motor 51, a connecting rod 52 and a positioning frame 53. The annular inner frame is fixed to the inner wall of the bottom tank body 13 and is used to support and limit the driving motor 51. The driving motor 51 drives the positioning plate 49 to rotate through the connecting rod 52 and the positioning frame 53. The connecting rod 52 is fixed to the output shaft end of the driving motor 51. The positioning frame 53 is fixed to one end of the connecting rod 52 passing through the three groups of circular plates. A plurality of positioning short rods are fixed on the side of the positioning frame 53 facing the sieve plate 47. The positioning short rods are adapted to the positioning holes 22 on the positioning plate 49. The connecting rod 52 is positioned on the positioning plate 49 through the positioning frame 53 and the positioning short rods, and the positioning plate 49 is fixed to the cylinder 41, that is, the driving motor 51 rotates the positioning frame 53, the positioning plate 49 and the cylinder 41 by driving the connecting rod 52.

[0087] When the driving motor 51 drives the positioning frame 53 to rotate through the connecting rod 52, the rotating positioning frame 53 causes the sieve plate 47, the circular sealing plate 48 and the positioning plate 49 to rotate synchronously through the positioning short rod, and the cylinder 41 fixed with the sieve plate 47, the circular sealing plate 48 and the positioning plate 49 rotates synchronously, wherein the baffle group 44 is limited by the steel pipe 32, so that the cylinder 41 rotates relative to the baffle group 44, the steel pipe 32 and the tank body 1, that is, the steel pipe 32 rotates relative to the cylinder 41. When the steel pipe 32 rotates in the cylinder 41, the resin inside the annular chamber is stirred, the microbial film adhering to the resin surface is removed, and the resin surface is cleaned so that the resin can accept the regeneration liquid to achieve regeneration. Secondly, the high-pressure water and regeneration liquid sprinkled from the steel pipe 32 are fully sprayed on all resin surfaces to prevent the existence of spraying dead corners in the annular chamber, resulting in incomplete resin cleaning or poor regeneration efficiency.

[0088] The annular chamber passes through the top of the cylinder 41 to form multiple diversion holes, and a pressure valve 45 is sealed at the diversion holes. The pressure valve 45 moves upward due to the water pressure inside the annular chamber, opening the diversion holes, which only allows water to flow in one direction. Its shape and principle are the same as those of the right seal 432. If the right seal 432 is to form a double-sided movement, the pressure on the other side is the pressure given by the left seal 431.

[0089] A resin adsorption tank for water treatment further includes: a processor, wherein a regulating system for regulating a water path in the resin adsorption tank for water treatment is configured in the processor, the regulating system including a monitoring unit, a data processing unit, a control unit, and an execution unit;

[0090] The monitoring unit includes a parameter sensor, which detects the iodine ion concentration β at the water outlet 15 in real time through the parameter sensor;

[0091] The data processing unit is configured with a concentration threshold value, and the data processing unit is used to obtain the iodine ion concentration β at the water outlet 15 in real time, compare it with the concentration threshold value, and generate an adjustment signal;

[0092] The control unit receives the adjustment signal, updates and analyzes the adjustment signal to generate an execution signal;

[0093] The execution unit is used to receive the execution signal and control the magnetic valve 43 to adjust the opening and closing of the pipeline based on the execution signal to adjust the water flow path.

[0094] The control unit is configured with a processing strategy for generating an execution signal, the processing strategy is used to obtain the iodine ion concentration β at the water outlet 15, and the data processing unit is used to obtain the real-time iodine ion concentration β at the water outlet 15, and compare it with the concentration threshold, and generate an adjustment signal to determine whether the iodine ion concentration in the resin is sufficient;

[0095] The steps for determining whether the iodine ion concentration in the resin is sufficient are as follows:

[0096] Obtain the iodine ion concentration β at the water outlet 15;

[0097] Based on the real-time iodine ion concentration β at the water outlet 15, the concentration is compared with the concentration threshold;

[0098] The iodine ion concentration β is compared with the concentration threshold. If the iodine ion concentration β is less than the concentration threshold, it indicates that the iodine ion concentration in the resin is insufficient, and an adjustment signal is generated. The adjustment signal is analyzed and updated based on the adjustment signal to generate an execution signal for controlling the adjustment of the magnetic valve 43.

[0099] The above iodine ion concentration β is compared with the concentration threshold. If the iodine ion concentration β is greater than or equal to the concentration threshold, it indicates that the iodine ion concentration in the resin is sufficient and no adjustment signal is generated.

[0100] Treatment strategies include:

[0101] Monitor the iodine ion concentration β of the liquid after entering the primary chamber as it flows through the water outlet 15, compare the currently acquired iodine ion concentration β at the water outlet 15 with the concentration threshold, generate a regulation signal if the iodine ion concentration β is less than the concentration threshold, refresh and analyze the regulation signal to generate an execution signal, and control the execution unit based on the execution signal to adjust the magnetic valve 43, thereby closing the magnetic valve 43 leading to the primary chamber and opening the magnetic valve 43 on the pipe leading to the secondary chamber, so that the liquid enters the secondary chamber;

[0102] Monitor the iodine ion concentration β of the liquid after entering the secondary chamber as it flows through the water outlet 15, compare the currently acquired iodine ion concentration β at the water outlet 15 with the concentration threshold, generate a regulation signal if the iodine ion concentration β is less than the concentration threshold, refresh and analyze the regulation signal to generate an execution signal, and control the execution unit based on the execution signal to adjust the magnetic valve 43, close the magnetic valve 43 leading to the secondary chamber, and open the magnetic valve 43 on the pipe leading to the tertiary chamber, so that the liquid enters the tertiary chamber;

[0103] Monitor the iodine ion concentration β of the liquid after entering the tertiary chamber as it flows through the water outlet 15, compare the currently acquired iodine ion concentration β at the water outlet 15 with the concentration threshold, and generate a regulation signal if the iodine ion concentration β is less than the concentration threshold. This signal is refreshed and analyzed to generate an execution signal, and the magnetic valve 43 is controlled based on the execution signal to close the magnetic valve 43 leading to the tertiary chamber and open the magnetic valve 43 on the pipe leading to the quaternary chamber, allowing the liquid to enter the quaternary chamber.

[0104] Monitor the iodine ion concentration β of the liquid after entering the four-stage cavity and flowing through the water outlet 15, compare the currently obtained iodine ion concentration β at the water outlet 15 with the concentration threshold, and generate an adjustment signal if the iodine ion concentration β is less than the concentration threshold. Refresh and analyze the adjustment signal to generate an execution signal, and control the execution unit based on the execution signal to adjust the magnetic valve 43 and close the magnetic valve 43 leading to the four-stage cavity.

[0105] The sewage from the primary, secondary, tertiary and quaternary chambers impacts the pressure valve 45, causing the pressure valve 45 to open and the sewage to flow out through the outlet 15. When the magnetic valves 43 on the pipes leading to the primary, secondary, tertiary and quaternary chambers are all closed, the pressure pump and the drive motor 51 are turned on, and the pressure pump is used to pressurize the external fluid to impact the liquid storage tank 31 to form high-pressure water, and the water is sprayed out at high pressure through the steel pipe 32 to flush all the resins and stir the resin to make it clean. After the resin is flushed, the regeneration liquid is extracted by the pressure pump and sprayed on the surface of the resin to regenerate the resin.

[0106] After cleaning and regenerating the resin, the wastewater is continued to be treated to achieve the overlap of sterilization mode and cleaning and regeneration mode.
