Description

Small device for the extraction of fully demineralized water.

The invention relates to a small device for the extraction of fully desaizted Two different versions of water. Once carried out in such a way that 1.) the regeneration of the used ion exchange material, as if pale, happens that one the used ion exchange material is removed from the device and stored in separate Send containers to a regeneration station or the complete device for regeneration sends to this regeneration station.

2.) On the other hand, carried out in such a way that this regeneration takes place on the spot can be carried out in the device.

Devices of the first design are known.

The innovation in this version concerns that the device accordingly the water hardness and the required amount of desalinated water, make it variable can by placing (see Fig. 1) pipes between a bottom piece (3) and a head piece (4) Add in any amount (loaf) to accommodate the ion exchange material can. These pipes are firmly welded into the head and pieces of sod.

The bottom piece (3) has threaded connection pieces (7a + 7b) on which Martwasser inlet (5) and soft water outlet (11) are screwed on. in the threaded fittings (7a + 7b) are plug-in screens (8a + 8b), which are used to empty the cation and anion exchange material can be removed.

A sieve (9) is housed in the head piece (4), which allows over-flushing of the ion exchange material from the container (la) into the container (lb) prevented.

A corresponding hole (lo) in the head piece (4) enables the passage the water to be treated from the container (la) and the container (1b).

An adjustable cy-pass is incorporated in the base piece (@), which it enables different purposes (e.g. @.

e.g. for aquariums) to obtain appropriately blended water.

This version works on the well-known principle: in two separate ones Chambers (1a + 1b) are two different ion exchange resins e.g. cation and Anion exchanger housed.

The device can be made in a transparent design and ~ the Cation exchangers can be provided with a color indicator, so you can recognize from the discoloration of the cation exchange material to what extent this is in its capacity is exhausted. When completely exhausted, the material will run out The two chambers are removed separately and must be regenerated with acid or alkali.

It must be sent to a regeneration station for this purpose.

The costs for shipping and regeneration as well as returning to the consumer, are disproportionately high, especially for small devices, compared to the achievable amount of money.

This is a well-known disadvantage of local desalination units.

In order to avoid the above disadvantage, the present invention developed the second version.

Here, especially in the case of small-scale systems, the consumer can use the least Taste the regeneration lotion in a simple way with the necessary regeneration agents do it yourself.

Compared to version 1, the device then has the following change Open: The head piece (4) (see Fig. 2) is like the bottom piece (3) with two threaded connectors (14a + 14b) carried out.

Both threaded connection pieces come with screw caps (1 5a + 1 5b) as well Cover plate (16as16b) closed.

The head piece (4) has the same by-pass device as the bottom piece (3).

Soft water is obtained in the usual way.

The regeneration can now be carried out as follows: 1.) The by-pass (17) in the head piece (4) and the by-pass (12) in the sod piece (3) is closed.

2.) The caps (15a + 15b) are unscrewed.

o.) on the threaded connection above the chamber (la) is a funnel put on and the necessary for the regeneration of the cation exchange material Regenerating agent (e.g. appropriately diluted hydrochloric acid) through from top to bottom sent the ion exchange material.

4.) - The chamber (ib) is correspondingly with the one for the regeneration necessary regenerating agent (diluted sodium hydroxide solution) is regenerated.

The flow of the two regenerants must be extremely slow, so that a correspondingly intensive regeneration takes place.

This can be achieved in that the two connecting pieces (5 + 11) have a corresponding aperture so that the required pass is achieved will.

5.) Rinsing out (clear rinsing) of the two ion exchange materials can then be done from below via the connections (5 or 11) in the known way.

6.) The caps (15a- + 15b) with the cover plates (16a + 16b) are unscrewed, the by-pass (17) and, if desired, the oy-pass (12) opened again Uas device is regenerated and ready for use again.

Claims (3)

Patent claim Baltzer 6 Kleingertit for the production of fully demineralized water. 1.) Small red for the production of fully demineralized water made of a weldable, transparent plastic, characterized in that between a suitably constructed oodenstijck and a head piece of pipes to accommodate the various ion exchange materials (cation exchangers and anion exchange material) are welded according to the required Amount of desalinated water can be of any length and that in its head piece, those for carrying out the regeneration at the installation site of the device Devices such as screw connection and sealing caps have integrated, which also provided with a by-pass that may be requested for certain purposes are. 2.) Small device for the extraction of fully demineralized water according to claim 1 characterized in that any other ion exchange material in the tubes can be filled to obtain a certain water quality. 3.) Small device for the extraction of fully demineralized water according to claim 1 and 2 characterized in that the normally located in the top and bottom pieces Passages for the water for carrying out the regeneration with a device are provided, which enables this passage to be closed. Small device for obtaining fully demineralized water according to claim 1 characterized in that instead of a weldable and transparent plastic any other materials can also be used. 308834/0720 L. e e r e i t e
