Abstract

PURPOSE:To remove bleaching powder contained in the water to be purified and to generate sufficient amt. of Ca ion in the water passing through the purifier at a considerably high flow rate by packing cation exchange resin mixed with a necessary amt. of remover for bleaching agent prepd. by solidify ing sodium thiosulfate with gypsum, in a vessel for passing water to be cleaned. CONSTITUTION:Cation exchange resin 3 exchanged in the first stage with NaCl is packed together with a necessary amt. of remove 4 for bleaching agent prepd. by solidifying 5-10wt.% sodium thiosulfate with gypsum in a vessel 1 for passing water. By this constitution, Ca<++> ions are liberated quickly from the cation exchange resin even if water is passed therethrough with a considerably large flow rate, and drinking water of high quality freed of bleaching agent and having 60-100ppm Ca<++> concn. which is believed to be effective for maintaining health is obtd. Further, the cation exchange resin is restored automatically to the state suitable for Ca<++> liberation during it is unused. Therefore, the resin is always held in the condition for liberating Ca<++> when it is used, and durability can be prolonged.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a water purifier that decalcifies drinking water such as tap water, well water, etc. and makes it Ca-enriched mineral drinking water.

[Prior Art] Conventionally, descaling water such as tap water has been commonly practiced. Also, there is no need to drink tap water! Calcium ions, which are said to be good for health, are in short supply, and in order to increase the amount of calcium ions in ξ, stone 981 is immersed in water to generate and quantify calcium ions by dissolving the gypsum.

[Problem that the invention seeks to solve]

In the conventional method of using gypsum, which generates calcium ions, its dissolution rate is slow. However, there was a problem in that only drinking water with a low concentration of calcium ions could be obtained.

[Rounding method to solve problems]

The present invention aims to solve these problems and provide a practical water purifier that is capable of descaling and generating approximately 60 to 1100 pp of calcium ions even in water at a considerable flow rate. The main structure of this water purification system is that a cation exchange resin is filled in the container through which water passes, and a required amount of a bleaching agent made of thorium thiosulfate solidified with gypsum is mixed therein. It is in.

[Effect]

In Jin's invention, if a container is filled with cation-exchanged N (R-8O3Nm) which has been ion-exchanged with basic salt, the dissolved C- It exchanges ions with R(SO3) and becomes Ca. If tap water or the like is poured into this container and used in this state, the cation exchange tree layer instantly exchanges ions with the nine common salts NaCl and K contained in the tap water.

R(So,)2Ca + 2N&CI-, R(-8o3
When the reaction of N+CaCA'z occurs, C1+ is instantly released at a fast reaction rate, and mineral drinking water enriched with C and -H- can be obtained. At the same time, the sodium thiosulfate from which the descaling agent has been eluted performs a descaling action, making it possible to obtain drinking water that is good for health. Furthermore, when no water is used, the gypsum descaling agent is eluted into the water remaining in the container 4, and the cation exchange resin becomes R (-80, Na
), to R(So,)2Cm to return to a state in which KC- is generated the next time water is used. In general, an hour without using water is longer than using water, so cation exchange @ fat can be constantly changed to 80← (SOz)2 Ca, and Cm is ready to be released. It is.

〔Example〕

The embodiment shown in the drawings is a descaling agent in which sodium thiosulfate NM 25203 is contained in gypsum in an amount of 5 to 1 G@li%, solidified into lumps, and mixed into cation-exchanged IIM fat for about 30 minutes. In the real example of C, if tap water is used as KtIL in the container, 60 to 1100 pp (D concentration) Ca+ can be dissolved.In the figure, (1) is the container, (2) is the water pipe, is a granular corner ion exchange resin, (
4) is a descaling agent.

〔Effect of the invention〕

According to the above alK according to the present invention, →←Ca can be rapidly released from the cation exchanger 11AI even when water is passed through at a considerable flow rate, and the human body Ka is lowered 66
G-1100pp Cm 9 degree decalcified high quality drinking water can be obtained. When not in use, the cation-exchanged am can be released by pressing #-, and it can be automatically restored, and when in use, it is always ready to release a high concentration of C++, and when used for long periods of time, it can release m. If you can lengthen the length, you will see better results.
