Description

Two way control type water conditioner for ion exchange resin clear washing}

The present invention relates to a water softener of bi-directional water circulation structure which has excellent soft water converting ability and is easy to regenerate ion exchange resin, and more specifically, it is a granular special polymer compound, which is located at the bottom of the soft water tank filled with ion exchange resin. Due to the structural characteristics of the conventional water softener, which converts raw water into soft water by introducing raw water and up-dispersing ion exchange, the channeling phenomenon that flows down only a part of the ion resin or a quadrilateral layer that does not flow the raw water is generated. By solving the problems that the regeneration efficiency is lowered and the service life is reduced, the water tank can be circulated evenly without the dead layer and the water tank is formed with a simple bi-directional water circulation structure to selectively adopt the upward or downward circulation system. Whether the resin contact area can be expanded and evenly distributed The present invention relates to a bidirectional water circulating water softener having an improved structure that can be formed in the form of a zigzag channel to maximize water softening efficiency and regeneration ability.

Water softener is soft water (smooth water), which is pure natural water, contains excessive amounts of harmful minerals such as calcium, magnesium and iron due to air pollution, soil pollution, and aging of water pipes. Sodium (Na) type cations in soft water tanks that are contaminated, hardened groundwater, and tap water by solving problems that threaten daily life and life, such as inadequate and causing skin diseases and promoting skin aging. It is a device that converts minerals such as calcium, magnesium, and iron in raw water into sodium ions (Na ⁺ ) in the resin and converts them into soft water, which is natural water.

If the water softener is used for a certain period of time, the sodium (Na) component is considerably reduced by continuous contact with the raw water of high hardness, and the hardness component is excessively adsorbed to the cation exchange resin, so that the exchange capacity by adsorption removal is improved. The saturation of soft water decreases and the resin is repeatedly made by passing a salt solution (salt, NaCl) and adsorbing sodium (Na) in brine to remove the hardness components adsorbed on the cation exchange resin. It is being used by reproducing.

A typical water softener structure has an ion exchange resin as a medium inside a soft water tank made of a synthetic resin or a stainless steel cylindrical cartridge case as shown in FIGS. 4 and 5, and is generally different according to the inflow direction of raw water. In the furnace, raw water inlet through which water is connected to a connecting pipe or connecting hose is formed, and the raw water (hard water) obtained through the raw water inlet is converted into soft water while moving up and down through the ion exchange resin layer filled in the case. Located on one side of the configuration is to be used as drinking or living water by being discharged to the outlet connected to the shower or water.

However, the water softener is a single type or inlet having a raw water inlet formed in only one of the bottom or the side of the cartridge-type softening tank in which the ion exchange resin is simply embedded (FIG. 4) or an artificial stirring device is installed in the resin layer (FIG. 5). The drainage port is installed at the center of the upper and lower ends of one case, and is formed in various configurations, such as a multi-stage type (FIG. 6) in which individual cartridges of the pre-treatment and main processing functions are sequentially connected in parallel. The channeling phenomenon that flows down only a part of the resin or the quadrilateral layer in which the raw water does not flow, as well as in the latter case (FIG. 6), the water conversion efficiency or the regeneration efficiency due to excessive loss of water pressure through the cartridges sequentially connected There is a problem that this is reduced and the service life is shortened.

That is, the above-mentioned conventional techniques are attached to a regeneration vessel in which salt is connected to the brine inlet at the top of the softening tank, or connected to an external regeneration vessel by a separate connection pipe to the ion exchange resin of the softening tank having a reduced exchange capacity. Repeatedly regenerating the ion exchange resin by injecting brine through the brine inlet, the flow direction is fixed upward or downward, so that only a specific layer of the ion exchange resin, which is a filter material, selectively flows, thus creating a quadrilateral layer. As a result, the contact reaction area is reduced and eventually the feed water is not evenly circulated, which inevitably imposes a structural problem that inevitably leads to low water and regeneration efficiency.

Therefore, in order to widen the contact area with the ion exchange resin and to mix salt water well, an artificial means such as a stirrer should be used, and thus, the regeneration work is cumbersome and the efficiency is lowered compared to the work labor, so that its working effect is partial and incomplete.

The present invention has been made to solve the above-mentioned problems, the proper water pressure is maintained so as not to generate the channeling phenomenon and the quadrangular layer of the conventional water softener, and the contact reaction area of the water and the resin without a separate stirring device is Forming a soft water tank in the form of an elongated zigzag inclined at a predetermined angle to maximize the supply water evenly mixed with the ion resin, and the water supply pipe connected to the water supply to the upper and lower sides of the soft water tank and the drain pipe connected to the shower A three-way valve is used to control the flow direction of the up and down streams respectively. As a simple bi-directional water circulation structure, an upward or downward circulation system can be selectively adopted to maximize the water efficiency and regeneration capacity. The water softener of bi-directional circulation structure is easy to recycle the exchange resin. There is a purpose in the blank.

And a bidirectional simple water circulation system for selectively passing water upward or downward when regenerating the resin, and a water softener having a bidirectional circulation structure for maximizing softening efficiency and regeneration ability.

The present invention is designed so that the channeling phenomenon of the conventional cylindrical water softener in the form of one or a plurality of parallel connection cartridges filled with ion exchange resins converting hard water into soft water is eliminated. The first feature is to form a soft water tank to minimize the loss of water pressure and widen the surface area of the contact reaction between the resin and the raw water by the thin and long zig-zag shaped tube, and the upper and lower sides of the zigzag-shaped soft water tank are respectively A second feature is a water circulation structure in which a water supply pipe and a drain pipe which select a water flow direction by a plurality of switching valves are provided in dual and a water flow direction which supplies water to a shower or tap water by selecting a downward or upward water flow direction.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The soft water tank 20 made of a zigzag hollow tube according to the present invention is made of a synthetic blower such as polypropylene or polyethylene as a raw material. blow) It is made of a multi-stage bent tube in a zigzag form by the molding method, and the inside of the tube of the soft water tank 20 is located in a plurality of corners that are converted to the direction of the curved soft water tank, the cap 21a is screwed Open the cap 21a of the support entrance tube 21, fill the cation exchange resin, and contaminate the hardened tap water with sodium (Na) -type cation exchange resin to supply minerals such as calcium, magnesium and iron in raw water. by substitution of the sodium ions (Na ⁺⁾ will be a function of the training is water converted in the nature, as to form a soft water tank 20 to the elongate channel and the enemy via Touch sensitive area and therefore the expansion of the raw water is hard water is passed through as evenly mixed entitled to receive the ion exchange resin is to maximize the training document conversion efficiency because sufficient reaction.

The above-described zigzag soft water tank 20 is inclined at a predetermined angle (an inclination angle of about 5-10 degrees) so that water pressure loss is small so that water flows in and out easily between adjacent pipes, and the contact area between resin and raw water and resin is reduced. The inner diameter is slightly expanded to increase the width, so that the passage of fluid is easily formed. A long, narrow zigzag channel with a diameter of about 10-15 cm is formed, and the raw water reacts sufficiently without artificial agitation. It is embedded in a rectangular box-shaped case 10 which is beautifully designed with a high compact size and has a decent appearance.

The regeneration liquid connecting pipe 22 with the cap 22a is connected to the upper side of the soft water tank 20 of the tubular body formed as described above and is connected to both sides of the upper connecting portion 23 and the lower connecting portion 24 as a seam. The water supply pipes 29a and 29b communicating with the water are branched by a 3 way valve 27 so that the water supply main pipe 29a is directly connected to the lower connection 23, and the water supply branch pipe 29b is upwardly directed. The drain main pipe 30a, which is switched to communicate with the upper connection part 24 and directly connected to the shower 25, is directly connected to the upper connection part 23, and is installed in the middle of the water supply pipe. The drainage branch pipe 29b vertically extended by 28 is connected to the lower connection part 24 to share the drainage passage, and consequently, the upper connection part 23 and the lower connection part 24 of the soft water tank 20. Water pipes 29a, 29b and drain pipes 30a, 30b each formed in plural By controlling the flow of water (supply water) in both directions, it is formed to pass the quantity of water selectively up or down during soft water and regeneration, and the water is represented as one, but the water 26 uses a T-shaped connecting valve to Hot water can also be piped separately.

In general, the regeneration of water softener is repeated for a long time, so that the sodium (Na) component decreases considerably due to continuous contact with raw water of high hardness, and the hardness component is excessively adsorbed on the cation exchange resin, so that the exchange capacity by adsorption removal The brine is injected into the deionized soft water tank through the brine inlet, and the brine adsorbs sodium (Na) and regenerates and restores the function of the ion exchange resin. Backwashing process to prevent turbidity by countercurrent flow to remove turbidity, rinse process to wash resin, and regeneration injection to regenerate ion exchange resin by injecting regenerator (salt water). The process is repeated with the flow of water upward or downward, and in the present invention, the water supply direction switching valve 27 and the draining direction before The valve 28 is used to adjust the water supply and drainage direction up and down, and connect the branch pipes in the middle of the drainage and water supply main lines to simplify the pipe structure and to selectively switch the flow of water, thereby restoring the function of the ion exchange resin. Regeneration was easy.

Hereinafter, the operation of the present invention of the present invention will be described in detail.

First, the water flow is upwardly or downwardly selected and adjusted by the water supply direction switching valve 27 (three-way valve) formed to be connected to the water supply pipes 28a and 28b on the outside of the case 10, and to adjust calcium, magnesium, iron, and the like. When a certain amount of raw water containing the mineral hardness component of is continuously supplied to the soft water tank 20, it passes through a sodium (Na) type cation exchange resin, so that minerals such as calcium, magnesium and iron in the raw water are added to sodium ions in the resin ( Na ⁺ ) is replaced with soft water, and at this time, a predetermined amount of raw water is predetermined in the zigzag conduit-shaped soft water tank 20 having an appropriate width by selecting the water supply direction switching valve 27 and the drain direction switching valve 28. The water softening process is continuously carried out through the cation exchange resin layer without any gap while maintaining the water pressure, and the treated soft water flows to the drain pipes 30a and 30b and is discharged to the shawigi 25. (For example, if the raw water from the water supply flows directly into the water supply main pipe 29a, it is immediately discharged into the drainage main pipe 30a, and when it flows into the water supply branch pipe 29b, it turns around the water softening tank (downward). Will be discharged via)

In addition, when regenerating the soft water tank 20 whose exchange capacity is reduced by adsorption removal due to the long-term repeated use of the ion exchange resin, the water flow is increased by using a switching valve by using the same softening operation as described above. Selective downward adjustment is used to switch the flow of fluid, backwashing process to make the raw water flow in the opposite direction of water flow, rinse process to wash the resin, and regeneration agent (salt) The water supply pipe 29 and the drain pipe 30 are supplied by adjusting the water supply direction switching valve 27 and the drain direction switching valve 28 by a simple operation in accordance with the process characteristics such as regeneration injection to regenerate the ion exchange resin. Ion-exchange resin of soft water tank 20, which is the same channel by repeating the opening or closing of main pipe 29a or water supply pipe 29b or drain main pipe 30a, drain pipe 30b. Regeneration operation to circulate alternately in the upward or downward direction is performed in parallel, and the regeneration solution injection pipe 22 having the cap 22a is in communication with the upper end of the soft water tank 20, so that the salt water is injected more smoothly. The brine replenishment is performed by opening the cap 22a from time to time as necessary, thereby completely eliminating the channeling phenomenon and the formation of the quadrature layer flowing only a specific portion of the ion exchange resin as a medium.

The present invention described above is not limited to the above-described embodiment as various substitutions and changes can be made by those skilled in the art without departing from the technical idea of the present invention. .

In this way, the present invention has a thin, long, zigzag-shaped tube that converts the idea to avoid the channeling phenomenon and the drift layer occurring in the conventional water softener, thereby minimizing the loss of water pressure and the contact reaction between the resin and the raw water.
