Description

Technical Field

[0001] This invention relates to the field of water treatment, and more particularly to an active scaling treatment device and method for high-hardness water. Background Technology

[0002] High water hardness has many negative impacts on both domestic and industrial water use. In daily life, high water hardness causes scale buildup when boiling water, resulting in poor sensory qualities. It also reduces detergent lather and washing effectiveness, and may contribute to kidney diseases such as kidney inflammation and kidney stones. In industrial applications, high water hardness easily leads to scale buildup in pipes and equipment, causing blockages. Furthermore, it can cause uneven heating in some heating equipment, and in severe cases, may even lead to explosions, threatening lives and property.

[0003] Existing water softening technologies mainly include: (1) Ion exchange method. It is a method that uses the exchangeable ions on a solid ion exchanger to exchange with the calcium and magnesium hardness ions in the water to remove hardness ions. Ion exchange is a reversible process. When the exchange capacity of the ion exchanger reaches saturation, it needs to be regenerated with regenerant. (2) Reverse osmosis method. It utilizes the selective permeability of a semi-permeable membrane. This membrane can only pass through water and other solutes cannot pass through. An external pressure higher than the osmotic pressure of the solution is applied to the raw water side to remove ions. (3) Electrodialysis method. Electrodialysis is a method in which anions and cations in the water will move in a directional manner under the action of an applied DC electric field. The selective permeability of the anion and cation exchange membranes is then used to achieve the purpose of water softening. (4) Traditional chemical precipitation method. It utilizes the principle of solubility product. Alkaline agents such as lime, sodium hydroxide and sodium carbonate are added to convert calcium and magnesium ions in the water into poorly soluble compounds that precipitate out. After coagulation, sedimentation and filtration, the water is finally softened.

[0004] Ion exchange involves a complex regeneration process for the ion exchange resin; incomplete regeneration affects the softening effect, and the treatment of regeneration wastewater is troublesome. Reverse osmosis is a rapidly developing water treatment method that can remove most dissolved salts, colloidal microorganisms, and organic matter from water. However, when treating high-hardness water, reverse osmosis membranes are prone to scaling, reducing permeability and significantly impacting membrane lifespan. Electrodialysis is a relatively mature water treatment technology, but it consumes a large amount of electricity, is prone to concentration polarization on the membrane surface, and has a relatively low ion removal rate.

[0005] Traditional chemical precipitation methods use reagents including lime, sodium carbonate, and sodium hydroxide. Lime is inexpensive, widely available, and used in large quantities, requiring significant space for storage. Furthermore, the small precipitate particles produced by lime softening can easily clog pipes. Sodium carbonate is suitable for water with hardness greater than alkalinity. Sodium hydroxide is primarily used to remove temporary hardness from water. These reagents require prolonged contact with hard water, resulting in large-scale treatment equipment with inconsistent treatment effectiveness. Summary of the Invention

[0049] "Prepared from" is synonymous with "comprising". The terms "comprising", "including", "having", "containing", or any other variations thereof as used herein are intended to cover non-exclusive inclusion. For example, a composition, step, method, article, or apparatus that includes the listed elements is not necessarily limited to those elements, but may include other elements not expressly listed or elements inherent to such composition, step, method, article, or apparatus.

[0050] The conjunction "composed of..." excludes any unspecified elements, steps, or components. If used in a claim, this phrase makes the claim closed, excluding materials other than those described, except for associated conventional impurities. When the phrase "composed of..." appears in a clause of the body of a claim rather than immediately following it, it limits only the elements described in that clause; other elements are not excluded from the claim as a whole.

[0051] When a quantity, concentration, or other value or parameter is expressed as a range, a preferred range, or a range defined by a series of upper and lower preferred values, this should be understood as specifically disclosing all ranges formed by any pair of any upper or preferred value with any lower or preferred value, regardless of whether the range is disclosed individually. For example, when the range “1–5” is disclosed, the described range should be interpreted as including ranges “1–4”, “1–3”, “1–2”, “1–2 and 4–5”, “1–3 and 5”, etc. When numerical ranges are described herein, unless otherwise stated, the range is intended to include its endpoints and all integers and fractions within that range.

[0052] In these embodiments, unless otherwise specified, the portions and percentages are all by weight.

[0053] "Parts by mass" refers to the basic unit of measurement that expresses the mass ratio of multiple components. One part can represent any unit mass, such as 1g or 2.689g. If we say that component A has "a" parts by mass and component B has "b" parts by mass, it means the ratio of the mass of component A to the mass of component B is a:b. Alternatively, it can mean that the mass of component A is aK and the mass of component B is bK (K is any number representing a multiplier). It is important to understand that, unlike the number of parts by mass, the sum of the mass parts of all components is not limited to 100 parts.

[0054] "And / or" is used to indicate that one or both of the described situations may occur, for example, A and / or B includes (A and B) and (A or B).

[0055] The embodiments of the present invention will be described in detail below with reference to specific examples. However, those skilled in the art will understand that the following examples are for illustrative purposes only and should not be considered as limiting the scope of the invention. Unless otherwise specified in the examples, conventional conditions or conditions recommended by the manufacturer are followed. Reagents or instruments whose manufacturers are not specified are all commercially available products.

[0056] Example 1

[0057] like Figure 1 As shown, this embodiment provides a high-hardness water active scaling treatment device, including: a treatment device body 1 with a accommodating space, the treatment device body 1 is provided with an inlet 10 for inputting hard water, a reagent inlet 11 for inputting reagents, a seed inlet 12 for inputting seed crystals, an outlet 13 for outputting soft water, and a seed outlet 14 for outputting seed crystals; the inner wall of the treatment device body 1 is provided with a baffle ring 2 for blocking water flow along the circumferential direction, the baffle ring 2 is arranged between the inlet 10 and the outlet 13 along the water flow direction.

[0058] In one alternative embodiment, the processing device body 1 can be configured as a cylindrical container with a dome. Additionally, the processing device body 1 can be equipped with auxiliary devices such as supports.

[0059] In use, reagents and seed crystals are added to the treatment device body 1 beforehand. The reagents include, for example, sodium carbonate, sodium hydroxide, or a mixture of both. The seed crystals can be garnet, calcium carbonate, or quartz sand particles with a particle size between 0.1 and 0.25 mm. Then, hard water to be treated is introduced into the treatment device body 1 through the inlet 10. The hard water flow carries the seed crystals to react with the reagents. The crystals produced by the reaction actively crystallize and grow on the surface of the seed crystals. As the particles increase in size, the resulting scale deposits are discharged from the seed crystal outlet.

[0060] Specifically, the following reaction occurs:

[0061] (1) When the alkalinity of the raw water is greater than its hardness, add sodium hydroxide solution.

[0062] NaOH→OH - +Na +

[0063] OH - +Mg 2+ →Mg(OH)2↓

[0064] OH - +HCO3 - →CO3 2- +H2O, CO3 2- +Ca 2+ →CaCO3↓

[0065] (2) When the hardness of the raw water is greater than its alkalinity, a mixed solution of sodium hydroxide and sodium carbonate is added. In addition to the reaction in (1), the following reaction also occurs in the solution:

[0066] Na₂CO₃→₂Na⁺ + CO₃²⁻ 2-

[0067] Ca 2+ +CO3 2- →CaCO3↓

[0068] Mg 2+ +CO3 2- →MgCO3↓

[0069] MgCO3 + 2H2O → Mg(OH)2↓ + H+ + +CO3 2-

[0070] In order to facilitate the optimization of the flow of hard water in the treatment device body 1, in a preferred embodiment, the inlet 10 and the seed outlet 14 are located below one side of the treatment device body 1 along the height direction, the outlet 13 is located above one side of the treatment device body 1 along the height direction, and the reagent inlet 11 is located between the baffle ring 2 and the inlet 10.

[0071] The administration of the reagent is preferably continuous during the treatment process or intermittent as needed.

[0072] Hard water is input from a lower position in the treatment device body 1. Under the action of water flow, it moves upward. After reaching the baffle ring 2, part of the water continues to move upward from the center of the baffle ring 2 and reaches the outlet 13 to exit the treatment device body 1. Most of the water moves downward, forming a circulation flow between the baffle ring 2 and the inlet 10, and interacts with the reagents and seed crystals. Figure 1(As shown in the middle circle) to fully react, so as to improve the processing effect without increasing the height of the processing device body 1.

[0073] In a preferred embodiment, to further optimize the function of the baffle ring 2 and ensure sufficient circulation of water between the baffle ring 2 and the inlet 10, the side of the baffle ring 2 facing the water flow ( Figure 1 The lower surface of the baffle ring 2 is configured as an arc shape (concave surface) recessed towards the inner wall of the processing device body 1, and the upper surface of the baffle ring 2 is configured as an inclined surface sloping from the inside out.

[0074] Example 2

[0075] like Figure 2 As shown, this embodiment provides a high-hardness water active scaling treatment device. In order to better optimize the reaction between hard water and the reagent and seed crystal, unlike Embodiment 1, a baffle plate 3 is horizontally arranged between the water inlet 10 and the seed crystal outlet 14 along the diameter direction of the treatment device body 1, dividing the treatment device body 1 into a water inlet zone I and a fluidization zone II. A water distributor 4 is uniformly arranged on the baffle plate 3, which is used to distribute the hard water in the water inlet zone I below the baffle plate 3 to the fluidization zone II above the baffle plate 3.

[0076] like Figure 3 and Figure 4 As shown, in order to optimize the hard water distribution effect and prevent seed crystals from leaking from the water distributor 4 into the water inlet area I, in a preferred embodiment, the water distributor 4 includes a water passage pipe 40 and a water distribution pipe 41, the water distribution pipe 41 being radially distributed with the water passage pipe 40 as the central axis; one end of the water passage pipe 40 is located below the isolation plate 3, and the other end is connected to the water distribution pipe 41; the pipe wall of the water distribution pipe 41 is hollowed out and the included angle between the water distribution pipe 41 and the water passage pipe 40 is an acute angle.

[0077] During treatment, hard water enters the inlet zone I through inlet 10, and then passes through the water distributor 4 on the isolation plate 3 to be evenly distributed into the fluidization zone II. It reacts with the seed crystals and reagents deposited on the isolation plate 3 and moves upward with the water flow. After reaching the baffle plate 2, part of the water flows downward to form a circulation and continue to react, improving the hard water softening efficiency. Part of the water continues to rise to the separation zone III. In this zone, the scale crystals sink to the bottom, the water and scale crystals are separated, and the water enters the clear water zone IV and is output as soft water through outlet 13.

[0078] Example 3

[0079] like Figure 5As shown, this embodiment provides an active scaling treatment device for high-hardness water. To further optimize the distribution of the agent and enhance the interaction between the agent and hard water and seed crystals, based on Embodiment 2, the agent inlet 11 is provided with a agent nozzle 15, and a guide tube 16 is provided below the agent nozzle 15 to restrict the flow direction of the agent from the agent nozzle 15. Below the guide tube 16 and in the center of the isolation plate 3, a conical dispersant 17 is provided for dispersing the agent from the agent nozzle 15.

[0080] like Figure 6 , Figure 7 and Figure 8 As shown, in an optional embodiment, the guide tube 16 is a hollow cylinder, including a guide tube inlet 160 with a conical surface, an intermediate hole 161 communicating with the guide tube inlet 160, and a dispersion hole 163 communicating with the guide tube outlet 162. The intermediate hole 161 and the dispersion hole 163 are both cylindrical, and the diameter of the intermediate hole 161 is smaller than the diameter of the dispersion hole 163.

[0081] A side view of the conical dispensing device 17 is shown below. Figure 9 As shown, the bottom view is as follows Figure 10 As shown.

[0082] In use, the agent is fed into the treatment device body 1 from the agent inlet 11 through the agent nozzle 15, and after being guided by the guide tube 16 and dispersed by the conical dispersant 17, it works together with the hard water from the water distributor 4 and the seed crystals deposited on the isolation plate 3 to soften the water.

[0083] Example 4

[0084] like Figure 11 As shown, this embodiment provides an active scaling treatment device for high-hardness water. To improve the automation level of the device, based on embodiment 3, an online alkalinity tester 5, an online hardness monitor 6, and a flow meter 7 are installed on the water inlet pipe connected to the water inlet 10; the chemical inlet 11 is connected to the chemical pipeline, and a metering pump 8 is installed on the chemical pipeline; the metering pump 8, the online alkalinity tester 5, the online hardness monitor 6, and the flow meter 7 are all electrically connected to the dosing control cabinet 9.

[0085] During treatment, the device can automatically add chemicals according to the raw water quality. Specifically, the dosing control cabinet 9 adjusts the dosage of sodium hydroxide and sodium carbonate by the metering pump 8 based on the raw water quality information collected from the online alkalinity tester 5, the online hardness monitor 6, and the flow meter 7. The chemicals added in the treatment device body 1 flow downward from the chemical nozzle 15 into the cylindrical guide tube 16. The conical dispersant 17 below the guide tube 16 disperses the chemicals to the upper part of the surrounding water distributors 4. While distributing water, the water distributors 4 carry the chemicals upward. The hard water, chemicals, and seed crystals interact to soften the water.

[0086] Example 5

[0087] like Figure 12 As shown, in order to better collect the treated soft water, an annular overflow trough 18 for collecting soft water is provided inside the upper part of the treatment device body 1. The annular overflow trough 18 is connected to the water outlet 13.

[0088] The active scaling treatment of high-hardness water using the treatment device provided in Example 5 is carried out in the following specific steps:

[0089] Hard water is introduced into the inlet zone I through the inlet 10, and then evenly distributed into the fluidization zone II through the water distributor 4 on the isolation plate 3;

[0090] Based on the raw water quality information collected from the online alkalinity tester 5 (monitoring frequency 30 min / time), the online hardness tester 6 (monitoring frequency 30 min / time), and the flow meter 7 (preferably an electromagnetic flow meter), the dosing control cabinet 9 adjusts the dosage of sodium hydroxide and sodium carbonate added by the metering pump 8. The dosage of sodium carbonate and sodium hydroxide in the dosing control cabinet 9 is 1.5 times the theoretical value. Specifically, when the total hardness (as CaCO3) of the raw water is 800 mg / L and the total alkalinity (as CaCO3) is 400 mg / L, the dosage of sodium carbonate solution is approximately 500 mg / L, and the dosage of sodium hydroxide is approximately 240 mg / L. For example, if the total hardness of a certain groundwater is 501.8 mg / L (as CaCO3), and the HCO3... - The alkalinity is 506.7 mg / L (calculated as CaCO3), and the total hardness exceeds the "Standards for Drinking Water Quality" (GB5749-2006). The upward flow velocity of the water in fluidization zone II is 60 m / h, which drives the upper seed crystals to flow upward. The seed crystals are garnet particles with a particle size of 0.1-0.25 mm, and the net bed height is 50 cm. The dosing control cabinet 9 adds approximately 300 mg / L of sodium hydroxide solution downward from the dosing nozzle 15 into the cylindrical guide tube 16. The dosing agent is dispersed to the upper part of the surrounding water distributor 4 through the conical dispersant 17 at the bottom of the guide tube 16. The water distributor 4 carries the agent upward while distributing water. The hard water, the agent, and the seed crystals interact to soften the water.

[0091] The seed crystals and reagents move upwards with the water flow. After reaching the baffle plate 2, part of the water flows downwards to form a circulation and continue the reaction, improving the hard water softening efficiency. Part of the water continues to rise to the separation zone III, where the scale settles to the bottom, separating the water from the scale. The water then enters the clear water zone IV and overflows into the annular overflow tank 18, from which soft water is output through the outlet 13. When the scale adhering to the seed crystals reaches more than 90% of the total particle mass, it is discharged from the seed crystal outlet 14, and new seed crystals are added through the seed crystal inlet 12. Both the discharge and addition of seed crystals utilize pressure control, adjusting the discharge and addition amounts according to the inlet water pressure. The measured total hardness of the water (calculated as CaCO3) is 90–110 mg / L, with a hardness removal rate of 78–82%.

[0092] This application solves the problem of poor hardness ion removal effect caused by the inability of existing chemical crystallization hardness removal devices to achieve rapid and uniform contact between the reagent and the seed crystals by setting a baffle ring 2 inside the treatment device body 1. Under the upward flow velocity of the raw water, the reagent and seed crystals flow upward together and circulate. This allows the water and reagent to come into uniform contact with each other. When the rising liquid comes into contact with the inwardly expanding baffle ring 2 set in the middle of the device tank wall, the water flow at the reagent nozzle 15 in the middle of the device drives it to flow downward and circulate for granulation.
