Description

Ion magnetizing water softener

Technical Field

The present invention relates to an ion magnetization water softener, and more particularly, to an ion magnetization water softener capable of removing various heavy metals and impurities contained in water and supplying soft water.

Background

Generally, water softeners are used to convert raw water, such as water from a water pipe, into soft water by ion exchange. The water softeners of the prior art are directly connected to the water pipe when in use, and therefore are constructed such that the inside of the water softener cartridge is normally subjected to the normal water pressure in the water pipe.

Korean utility model laid-open publication No. 1993-2693 discloses a water softener in which an ion exchange resin is contained in the upper part of a filter net of a cylindrical container, water is supplied from the upper part, and water is taken out from the lower part. The disclosed water softener is also provided with a brine inlet, and a regenerated water discharge tap at the bottom surface. However, the water softener of the prior art has a problem that it is difficult to perform internal cleaning, and the regenerated water remains on the bottom surface after cleaning, so that the regenerated water cannot be continuously discharged and the re-contaminated water may be used.

Further, korean utility model laid-open publication No. 1996 + 27157 discloses a water softener which can be used as a water purifier by removing impurities without using a power source and by exchanging only a part of ion exchange resin.

Detailed Description

The following describes the preferred embodiment of the present invention in detail with reference to fig. 1 to 5. In fig. 1 to 5, components having the same functions are denoted by the same reference numerals.

See fig. 1 and 2. The ion magnetization water softener 10 receives raw water such as tap water, and converts the raw water into soft water by ion exchange action for use by a user. A pipe for supplying raw water to the ion magnetization water softener 10 is connected to a lower portion of the soft water cylinder 20. A machine (typically a faucet or shower) 100 using treated soft water is attached near the underside of the soft water cartridge 20. The water exiting the machine 100 is soft water treated with ion exchange resin 200 (see fig. 4) in the soft water cartridge 20.

The ion magnetization water softener 10 is composed of a soft water cylinder 20, a water pipe 30, a lower end cover 50, an upper end cover 80, a flow rate adjusting member 60, and the like. The cartridge 20 has a lower opening 22 and an upper opening 24, and is provided at the inside thereof with an ion exchange resin 200 in the longitudinal direction. A coupling port 26 connected to the machine 100 is provided at a lower side of the soft water cartridge 20. The water pipe 30 is hollow 32, and is inserted into the center of the ion exchange resin 200 through the lower opening 22 of the cartridge 20.

The lower end cap 50 supports the water pipe 30, is connected to the lower side of the soft water cylinder 20, and supplies raw water from the outside to the soft water cylinder 20. The upper end cover 80 is connected to the upper side of the soft water cartridge 20, and provides awater path for discharging water in the soft water cartridge 20 from the upper region of the soft water cartridge 20 to the outside.

The water path adjusting device 60 adjusts the raw water supplied through the lower end cap 50 and supplies the adjusted raw water to the water pipe 30 or the ion exchange resin 200. The waterway adjusting means 60 is constituted by a flange 40 provided on the lower side of the water pipe 30 and an adjusting member.

The flange 40 seals the lower opening 22 when the water passage pipe 30 is inserted into the soft water tube 20, and forms a first water path 34 communicating with the hollow portion 32 of the water passage pipe 30 and a second water path 70 communicating with the ion exchange resin 200.

The adjusting member is connected to the lower end cover 50, and adjusts the flow of the raw water by closing one of the first water path 34 and the second water path 70 and opening the other. The adjustment member is composed of a ball 68, a spring 66, and switches 62, 64. Ball 68 moves along the surface of flange 40, blocking either first waterway 34 or second waterway 70. The spring 66 resiliently urges the ball 68 against the surface of the flange 40. Switches 62, 64 are provided on the lower end cap 50, supporting a spring 66 and moving a ball 68.

On the other hand, the upper end of the water pipe 30, the upper end of the second water path 70, and the lower end of the upper end cover 80 are provided with the filters 36, 44, and 84, respectively, and the upper end cover 80 is provided with the cock 82.

Fig. 3 is a diagram illustrating a water path switching operation of the ion water magnetizing and softening machine of the present invention, fig. 4 is a diagram illustrating a process in which the ion water magnetizing and softening machine of the preferred embodiment of the present invention purifies water, and fig.5 is a diagram illustrating a process in which the ion water magnetizing and softening machine of the preferred embodiment of the present invention removes internal contaminants.

When the switch 62 of the water passage adjusting device 60 is turned on to cause the raw water to flow into the water passage pipe 30 as shown in fig. 3 (a), the raw water passes through the first water passage 34 of the flange 40 and flows into the hollow portion 32 of the water passage pipe 30 as shown in fig. 4. The raw water is ionized by the ion exchange resin 200, converted into soft water, and discharged to the machine 100 for use.

When the switch 62 of the water passage adjusting device 60 is turned on to flow the raw water to the ion exchange resin 200 (B) shown in fig. 3, the raw water flows from the lower portion to the upper portion of the ion exchange resin 200 through the second water passage 70 of the flange 40 as shown in fig. 5. At this time, suspended matter on the upper portion of the ion exchange resin 200 floats to the upper portion of the water softening tank 20. In this state, when the cock 82 of the upper end cover 80 is opened, the suspended matter in the soft water pipe 20 is discharged to the outside. At this time, the filtering nets 36, 44 and 84 respectively provided at the upper end of the water passing pipe 30, the upper end of the second water passage 70 and the center portion of the lower end of the upper end cap 80 serve to prevent the ion exchange resin 200 from flowing into the hollow portion 32 or being discharged to the outside through the cock 82 during the above-mentioned process.

As can be seen from tables 1 and 2, representative ion exchange resins used in the ion magnetization water softener of the present invention are strongly acidic cation exchange resins. As the ion exchange resin, styrene-based resins, phenol sulfonic acid-based resins, and the like are used.

Styrenic resins are the most widely known strong acid cation exchange resins having a sulfo group (-SO) as an exchange group₃H) The skeleton of the copolymer is composed of a copolymer of styrene and benzene (divinyl benzene). Sulfonic acid copolymer (sulfonic acid polystyrene-DVB) is generally stable to strong acids and bases, is not attacked by oxidizing agents, and can be ion exchanged over the entire pH range due to the sulfonic acid exchange group. The ion exchange resin is brown to blackish brown, translucent, and generally, the color tends to be darker as the degree of crosslinking is higher. Further, its apparent specific gravity in water was about 1.3.

With respect to the stability of the sulfonic acid copolymer resin, the exchange capacity of the resin does not change below about 100 ℃ in the form of a free acid, and the resin is stable even at a high temperature of up to 120 ℃ in the form of a salt. When decomposed by heat, the exchange capacity, density and water absorption of the resin composition are reduced. For example, after heating at 186 ℃ for 24 hours, the exchange capacity decreases by 15-40%. Increasing the degree of crosslinking improves its stability to heat. The fundamental properties of the resin are determined by the type and nature of the exchange groups, the number of exchange groups (exchange capacity) and the degree of crosslinking. Here, the degree of crosslinking refers to a property related to a bridge (bridge) that functions to link a one-dimensional polymer into three dimensions, specifically, corresponds to a molecular mesh size in a resin, and generally indicates a DVB content. Sulfonic acid copolymer resins are one of the most widely used cation exchange materials and are commercially available as Diaion SK, Zeorex SA, Dowex 50, AmberliteIR-120, 112, and the like.

The phenol sulfonic acid resin is obtained by combining formaldehyde and phenol. Its exchange groups have both strongly acidic sulfonic acid radicals and weakly acidic phenol radicals. Thus, the exchange can be performed over the entire pH range. In the region where the pH is low, the sulfonic acid group itself undergoes an exchange reaction, and in the region where the pH exceeds 8, the phenol group also undergoes an exchange reaction. Thus, the exchange capacity varies with pH. Which has a smaller exchange capacity at low pH than the sulfonic acid copolymer resin. The phenol sulfonic acid resin is black spherical or granular, the expansion and contraction conditions are not obvious, and the mesh structure is not compact. Commercially available are Diaion K, Dowex 30, Duolite C-1, and the like.

An example of a method for testing the ion exchange performance of the ion magnetization water softener will be described below.

First, Ca is removed from hard water²⁺Or Mg²⁺And the like, have been currently used in the related industrial fields. The method for manufacturing the desalted water and the deionized water comprises the following steps: the water to be purified is continuously passed through a cation exchange resin layer or an anion exchange resin layer, or through a mixed ion exchange resin layer, while removing cations and anions.

Ion exchange materials for carrying out ion exchange performance experiments were prepared and ion exchange tubes were manufactured. That is, first, the ion exchange resin in a dry state is washed several times with fresh distilled water, and then soaked in distilled water for 2 to 3 days to swell it. In order not to dry the resin, it is preferable to store the resin in a bottle with a stopper filled with distilled water.

The size of the ion exchange tube or column depends on the amount of material to be separated and the ease of separation. In a simple experiment, a tube having a length of 20 to 80cm and a diameter of about 1 to 1.5cm is preferably used. When filling the ion exchange tube with the resin, it is necessary to fill the ion exchange tube with water so that the resin reaches the central portion and then fill the ion exchange tube with the resin slowly, taking care not to generate bubbles, furrows, and the like in the ion exchange column. If bubbles and grooves are generated in the column, the raw water is connected to the lower part of the exchange tube, and the water is slowly refluxed to suspend the resin, and then the resin is settled.

After the resin is filled, a plurality of glass fibers are coated on the upper surface of the resin in the tube, so that the resin is prevented from being scattered due to the solution flowing out of the separating funnel. After the ion exchange tube was prepared, for resin activation, the H-type cation exchange resin was treated with hydrochloric acid, the Na-type cation exchange resin was treated with NaCl, the OH-type anion exchange resin was treated with NaOH, and the Cl-type anion exchange resin was treated with HCl and NaCl, and these were reactivated.

In the reactivation, about 50ml of a reagent solution having an appropriate concentration of 2 to 6F was added to a resin to be used in a 50 to 100ml separatory funnel, and after the reagent solution was attached to the exchange tube, the cock of the separatory funnel was completely opened in advance, and the solution was discharged by using the cock at the lower portion of the exchange tube without paying attention to drying the resin in the tube.

In the cation exchange resin and anion exchange resin tubes, the hydrogen-form or hydroxyl-form activated resin reacts with NaCl solution, respectively, and HCl and NaOH are collected as effluent. Fully washing the activated exchange tube by distilled water until the effluent liquid is neutral. Then, the solution to be subjected to the experiment was put into a funnel, and an ion exchange reaction test was performed while allowing the solution to flow out at 1 to 2 drops per second, and the effluent was collected. After all the test solutions were discharged, the resin was washed with an appropriate solvent to discharge the ions and the solvent adsorbed in the resin.

Ni anion exchange resin pair in the following method²⁺And Zn²⁺Separation is carried out. If Ni is contained by treatment with strong HCl²⁺And Zn²⁺Mixed solution of (2), then Zn²⁺Will form ZnCl₃ ^-And ZnCl₄ ^2-A complex of the same, and Ni²⁺No complex is formed.

Thus, Zn is utilized²⁺The property of being able to form an anionic complex, Ni can be converted using an anion exchange resin²⁺And (5) separating. Namely, the acidic mixed solution is passed through an anion exchange resin column to form Zn in an anionic form^-The complex will absorbAttached to a resin, and Ni²⁺It passes straight through the resin tower. After the nickel ions are separated, distilled water is injected into the resin tube to wash the resin tube, thereby destroying Zn adsorbed on the anion exchange resin^-Complexing it with Zn²⁺Is discharged in the form of (1).

On the other hand, in order to separate Ni with a strong acid solution²⁺Using cation exchange resins with ions, then H⁺Will react with Ni in the resin²⁺The reaction is competitive at the active site, the ion exchange is incomplete, and Ni cannot be exchanged²⁺Completely separated out.

The present invention may be embodied in other various forms without departing from the technical spirit of the present invention. The above-described embodiments are merely illustrative of the technical contents of the present invention, and the present invention should not be limited to these specific examples. Various modifications may be made without departing from the spirit of the invention and the scope of the claims.

As described above, according to the present invention, it is possible to wash the inside of the soft water cylinder as long as the switching valve and the discharge valve are operated. That is, even a female user can easily operate, thereby increasing the convenience of use. Furthermore, the soft water supply path is isolated from impurities in the soft water cartridge when the soft water cartridge is cleaned, so that secondary contamination after cleaning can be maximally prevented.
