Column-shaped device for the production of partially desalinated and softened water.

The innovation concerns a device for the production of partially desalinated and also softened water using solid regenerants such as citric acid and table salt.

For household purposes it is often advantageous to use a partially desalinated and to have hardness-free water available. It has been shown in practice that such water has the usual disadvantages of the ealz-rich, but hardness-free water (e.g. turbidity, Staining) on the item to be treated.

Through the partial desalination - complete removal of the carbonate hardness the formation of the sodium bicarbonate produced during softening is prevented. The waters containing carbonate cause namely, unpleasant changes in taste when the water is heated in hot beverages and they also cause coffee and tea to bake in hot beverage makers through the formation of alkalinity.

Water containing bicarbonate is also a disadvantage for hydroponics, floriculture and aquaristics.

The production of partially desalinated and softened water with weakly and strongly acidic cation exchangers is known, however, the regeneration has so far been carried out in two successive regeneration processes with two regeneration agents.

It has now been found that this disadvantage can be avoided by using a columnar device in which the room the column 1 is divided into three parts by sieve inserts 9a, 9b, of which the two lower rooms with strong and weak acid

Cation exchangers are filled and the space above the sieve insert 9a serves as a release space for the periodic uptake of the solid regeneration agent mixture.

Furthermore, in the column of the room 1, there is a pipe 10 passing through the sieve inserts 9a and 9b which via «» in valve 7 the water to be treated from the tap into the lower part of the column with the weakly acidic cation exchanger flows out and flows through both cation exchangers in an ascending direction and leaves the column through the outlet 5.

In the cover 4 is a closable filler opening 8 for the solid Regeneration mixture and a screw cap 2 attached to the bottom. The latter is expediently in the regeneration by a Nozzle 3 replaced.

Appropriately, the valve 7 is designed as a switching valve, so that when regenerating the water flow is led directly into the release space to the device through the regeneration nozzle used to leave again.

With this innovation, the regeneration process and the washing out of the ion exchangers take place after the regeneration agent has been filled automatically without special maintenance under pressure by simple Switching over the two-way switch valve 7 and screwing in the regeneration nozzle 3.

For regeneration, substances such as those in the German patent 1 257 692 are described, can be used. Here, for the first time, there is a way for something that is reasonable for the household Regeneration with partial desalination and softening shown.

The innovation is explained in more detail with the aid of the accompanying drawing. The drawing shows the innovation in longitudinal section.

The device consists of a transparent and pressure-resistant plastic column 1 with a hemispherical bottom, which is either a screw cap 2 or a replaceable regeneration nozzle 3 carries and from a screw cap 4 on which a Drain valve 5 with a variable flow restriction nozzle 6, a two-way switch valve 7 and one that can be closed with a screw Filling opening 8 are located.

In the lower part there are two adjustable ones, with one Sealing tape sealed sieve plates 9a and 9b, which divide the column space into 3 variable spaces.

A plastic pipe 10 closed with a sieve 11 is possible from the switching valve 7, the two sieve plate penetrates * 9a and 9b and ends shortly before the calotte bottom of the lower part.

The upper sieve plate is fixed in its position with respect to the cover by a short piece of pipe 12 and so always same release space guaranteed.

The larger space under the second sieve plate 9b is filled with a weakly acidic cation exchange resin, the space above with a strongly acidic cation exchange resin. The space above the first sieve plate 9a - release space - is in operation with water, filled with regeneration salt or regeneration solution when regenerating.

In the case of the water treatment, the water flows through the resin via the plastic ear 10 from bottom to top,

a good distribution of the water flow is achieved through the dome base and the resin filling. The water flows first through the weakly acidic, then through the strongly acidic Cation exchanger and occurs over the drain valve 5 on screw cap 4 of the device.

For pressure regeneration, the two-way switch valve 7 is after Closing the hater supply switched to generating, the filler screw 8 as the lid is opened and the screw plug 2 at the bottom is removed. The water level in the loosening space drops down to the first sieve plate 9a. Now the Regenerating nozzle 3 screwed into the floor and the Regenerlersalzgemlsch, e.g. table salt and citric acid »are poured into the dissolving chamber. Then the filling opening 8 on the lid is closed and the water flow for regeneration via 7 and 3, by opening the water supply, released. The regeneration solution is now forced through the resin under pressure and under the Regeneration nozzle 3 caught in a vessel. After flow of 8 to 10 1, the regeneration and washing-out are complete. The pressure regeneration enables a steady and accelerated Regeneration and rinsing of the resins when using solid regenerants

The water supply via 7 is closed and the regeneration nozzle is again exchanged for the screw cap 2 and the switching valve 7 is then switched back to normal operation. The device is ready to work again.

The device can also be designed for certain purposes be that it is without a central tube, but in the order schwaeasauxez Cation exchanger, followed by the strongly acidic cation exchanger, is operated from top to bottom, whereby the

! Switching valve 7 of the cover 4 reversed at the bottom of the device and enables the two switching paths for operation and regeneration to the outside. But there is a water inlet valve attached to the lid.

It is also possible to operate the device both from top to bottom and from bottom to top »if the two resins mixed. However, with this procedure, the yield of partially demineralized water is based on the amount of water used Generating agent lower.
