Description
【０００１】
【産業上の利用分野】
本発明はイオン交換樹脂を使用する軟水器に関するものであり、詳しくは軟水器の樹脂層への通水が停止することによって軟水器内の水に硬度分が流出し、硬度分を含んだ水が軟水タンクへ供給されることを防止することのできる軟水器システムに関するものである。
【０００２】
【従来の技術】
ボイラー用給水など水の軟化処理を行う必要がある場合、軟化処理にはイオン交換樹脂の間を通水させることで硬度成分を除去する軟水器が広く使用されている。ところが、この軟水器の場合、樹脂層に通水が行われていないと、樹脂が取り込んでいた硬度分が軟水器内の水に流出してしまい、軟水供給再開時には硬度分を含んだ水が軟水使用機器へ送られることになっていた。
【０００３】
【発明が解決しようとする課題】
本発明が解決しようとする課題は、硬度分を含んだ水が軟水として給水されることを防止することのできる軟水器システムを提供することにある。
【０００４】
【課題を解決するための手段】
イオン交換によって原水を軟水とする軟水器、軟水器へ原水を供給する原水配管、軟水器で処理を行った軟水を軟水タンクへ送る軟水配管を持ち、軟水器へは断続的に通水を行う軟水器システムであって、軟水配管途中に分岐配管を接続し、軟水タンクと分岐配管のそれぞれへの通水を制御する通水制御装置を設けることで、軟水器から取り出された水が軟水タンクへ達しないように分岐配管によって水を排水または軟水器の上流側へ循環させることができるようにした軟水器システムにおいて、軟水器への通水を行っていない時間の計時を行うタイマー装置を設けておき、通水を停止してからの時間が設定時間に達すると、軟水器内の水を分岐配管を通して排水または軟水器上流へ循環させる。
【０００５】
【作用】
通水を停止していることによって軟水器内で硬度分が流出しても、軟水器内の通水が停止してからの時間が設定時間に達するごとに、軟水器内の水を排水または軟水器上流へ循環させて再度軟化処理を行うため、通水を停止していても軟水器内の水に含まれる硬度分は一定度以上となることはなく、通水時に硬度成分が軟水使用機器へ送られることを防止できる。
【０００６】
【実施例】
本発明の一実施例を図面を用いて説明する。図１は請求項１に関する一実施例のフロー図であり、図２はそのタイムチャートである。軟水器(3)へ原水を供給する原水配管(1)と、軟水器(3)から取り出した軟水を軟水タンク(9)へ送る軟水配管(2)を設けており、軟水配管(2)途中に通水制御弁(4)を設ける。軟水器(3)と通水制御弁(4)の間の軟水配管(2)に分岐配管(5)を接続し、分岐配管の他端は軟水器(3)の上流である原水配管(1)に接続しておき、分岐配管(5)には循環ポンプ(6)と逆止弁(7)を設けている。通水の制御はタイマー装置を持った制御装置(8)にて行っており、制御装置(8)は通水制御弁(4)、循環ポンプ(6)、および軟水タンク(9)に設けた水位検出装置(10)と接続している。
【０００７】
軟水タンク(9)に設けた水位検出装置(10)は、水位Ｅ１での水の有無を検出しており、水位が水位Ｅより高い場合には軟水の採水を停止し、水位が水位Ｅ１より低い場合には軟水の採水を行う。軟水を採水する場合、制御装置(8)は通水制御弁(4)を開き、循環ポンプ(6)は停止させた状態で軟水器(3)に原水を供給する。軟水器内へ供給した原水は、軟水器(3)内のイオン交換樹脂と接触することで硬度成分が取り除かれて軟水となる。軟水器(3)から取り出された軟水は、軟水配管(2)を通って軟水タンク(9)に溜められ、軟水使用機器(図示せず)は軟水タンク(9)の軟水を使用する。
【０００８】
軟水タンク(9)の水位が上昇し、水位Ｅ１で水有りが検出されると、軟水器(3)への通水を停止して、軟水の生成は中断する。制御装置(8)は通水制御弁(4)を閉じ、内部に設けているタイマー装置の稼働を開始する。通水を停止している時間があらかじめ入力されていた設定時間(Ｔ)に達すると、制御装置(8)は、通水制御弁(4)を閉じたままで一定時間循環ポンプ(6)を作動させる。循環ポンプ(6)を作動させると、軟水器(3)内にたまっていた水は軟水配管(2)・分岐配管(5)を通って原水配管(1)へ戻される。循環ポンプ(6)を停止し、通水が停止すると、制御装置(8)は再びタイマー装置による計時を行い、その後も設定時間(Ｔ)が経過するごとに循環ポンプ(6)を作動させる。通水が停止することによって軟水器(3)内で硬度分が流出しても、硬度分を含んだ水は再び軟水器(3)へ通水することで軟化処理を行うため、軟水の採水を長時間停止していても、軟水器(3)内で硬度分が流出して硬度の高い水が軟水器内にたまっているということはなく、軟水タンク(9)への軟水供給を再開したときには、軟化された軟水のみが送られるので、硬度漏れを起こした水が軟水タンク(9)へ送られることは無くなる。
【０００９】
【発明の効果】
本発明を実施することによって、通水停止中に発生した硬度分は通水停止中に除去するので、通水再開時に硬度分の含まれた硬水が給水されることを防ぐことができる。

[Industrial applications]
The present invention relates to a water softener using an ion-exchange resin, and more specifically, water in the water softener flows out of water in the water softener by stopping water flow to the resin layer of the water softener, and water containing the hardness is used. Water softener system capable of preventing the supply of water to a soft water tank.
[0002]
[Prior art]
When it is necessary to perform water softening treatment such as water supply for a boiler, a water softener that removes a hardness component by passing water between ion exchange resins is widely used in the softening treatment. However, in the case of this water softener, if water is not passed through the resin layer, the amount of hardness taken up by the resin will flow out into the water in the water softener, and when the soft water supply is resumed, water containing the hardness will be lost. It was to be sent to equipment using soft water.
[0003]
[Problems to be solved by the invention]
The problem to be solved by the present invention is to provide a water softener system that can prevent water containing hardness from being supplied as soft water.
[0004]
[Means for Solving the Problems]
It has a water softener that makes the raw water soft by ion exchange, a raw water pipe that supplies the raw water to the water softener, and a soft water pipe that sends the soft water that has been processed by the water softener to the soft water tank, and intermittently flows through the water softener. A water softener system, in which a branch pipe is connected in the middle of a soft water pipe and a water flow control device that controls water flow to each of a soft water tank and a branch pipe is provided, so that water taken out of the water softener is supplied to the soft water tank. In a water softener system in which water can be drained or circulated to the upstream side of the water softener by a branch pipe so as not to reach the water, a timer device that measures the time when water is not passed to the water softener is provided. In advance, when the time after the passage of water reaches the set time, the water in the water softener is drained through the branch pipe or circulated upstream of the water softener.
[0005]
[Action]
Even if the water content is stopped, the water in the water softener is drained or the water in the water softener is discharged every time the set time elapses after the water flow in the water softener is stopped Since the water is circulated upstream of the water softener and re-softened, the hardness contained in the water in the water softener does not exceed a certain level even when the water flow is stopped, and the hardness component is soft water when water is passed. It can be prevented from being sent to the device.
[0006]
【Example】
An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a flowchart of an embodiment according to
[0007]
A water level detecting device (10) provided in the soft water tank (9) detects the presence or absence of water at the water level E1, and when the water level is higher than the water level E, stops sampling of the soft water and stops the water level at the water level E1. If it is lower, take soft water. When water is softened, the control device (8) opens the water flow control valve (4) and supplies the raw water to the water softener (3) with the circulation pump (6) stopped. The raw water supplied into the water softener is removed from the hardness component by coming into contact with the ion exchange resin in the water softener (3) to become soft water. The soft water taken out of the water softener (3) is stored in a soft water tank (9) through a soft water pipe (2), and equipment using soft water (not shown) uses the soft water in the soft water tank (9).
[0008]
When the water level in the soft water tank (9) rises and the presence of water is detected at the water level E1, the flow of water to the water softener (3) is stopped, and the generation of soft water is interrupted. The control device (8) closes the water flow control valve (4) and starts operation of the timer device provided inside. When the time during which the water flow is stopped reaches the preset time (T) input in advance, the control device (8) operates the circulation pump (6) for a certain period of time with the water flow control valve (4) closed. Let it. When the circulation pump (6) is operated, the water accumulated in the water softener (3) is returned to the raw water pipe (1) through the soft water pipe (2) and the branch pipe (5). When the circulation pump (6) is stopped and the flow of water is stopped, the control device (8) again counts the time by the timer device and thereafter operates the circulation pump (6) every time the set time (T) elapses. Even if hardness stops flowing in the water softener (3) due to the stoppage of water flow, water containing the hardness is again passed through the water softener (3) to be softened. Even if the water is stopped for a long time, there is no possibility that the hard water flows out in the water softener (3) and the water with high hardness is accumulated in the water softener. When the operation is restarted, only the softened soft water is sent, so that the water that has caused the hardness leak is not sent to the soft water tank (9).
[0009]
【The invention's effect】
By carrying out the present invention, the hardness generated during the stoppage of the water flow is removed during the stoppage of the water flow, so that it is possible to prevent the supply of the hard water containing the hardness during the restart of the water flow.
