Definitions
- the present invention relates to a device for treating drinking water.
- PCT application WO 99/48822 describes that a weakly acidic ion exchange resin in the Ca form triggers catalytic lime precipitation from a calcareous solution on its surface.
- This process can be used for physical water treatment: the lime crystal nuclei formed on the surface of the catalytically active granules easily detach from the surface and are themselves crystallization centers in the supersaturated water. The growth of these crystallization centers binds the excess calcium and carbonate ions to themselves and failure processes on pipe and boiler walls are suppressed in this way.
- PCT application WO 99/48822 also contains technical descriptions of how preferably water treatment devices are designed with this catalyst material and are used in drinking water installations. Essentially, these water treatment devices are made up of a pressure-resistant container, a nozzle base and a granulate-retaining filter element. The original idea was to install this catalyst technology in the cold water line of the drinking water system.
- the process water has a significantly longer average residence time in the system. This dwell time allows a longer treatment time for the water. This enables efficient water treatment even with small, compact catalysts.
- the catalyst granulate can be ideally disinfected with warm or hot water; disinfection makes sense for safe operation in the drinking water area due to the large surface of the material from a hygienic point of view.
- the catalyst granulate is preferably used in the hot water area.
- FIG. 2 shows a device for disinfecting a water treatment unit, which is introduced as an independent device in the cold water or hot water part of a drinking water installation.
- the installation of such an additional device creates additional effort and space.
- this additional device requires an energy supply for heating the water to be treated. This results in additional energy consumption, which cannot be fully recovered in the drinking water installation due to the heat losses that occur.
- the circulation via the catalyst granulate in a wall-mounted electric boiler by means of a circulation line is known.
- Circulation line with a circulation pump increases the investment and the
- the object of the invention is therefore to integrate a water treatment unit into the drinking water installation in such a way that it does not create any additional space and energy requirement and enables optimal water treatment.
- the water-treating substance preferably the catalyst granulate
- a technical liquid-filled system directly into the area where, for example, the lime problems occur.
- adapted technical designs are required for the container of the water-treating substance, preferably the granulate.
- the technical system itself is not intended to receive the water-treating substance, preferably the catalyst granulate, and fulfills another technically necessary purpose. This can be, for example, the storage (storage, buffering) of a liquid, in particular storage of hot water (energy storage) for later consumption. Alternatively, however, the technical system can also be used to heat the liquid, to transfer the liquid, or to combine these functions.
- Limestone formation can be prevented, for example, by installing a water treatment unit according to the invention which contains the water-treating substance, preferably the catalyst granules.
- Essential features of this device are that it itself is not suitable to provide the function of water heating and storage and that it can accommodate the water-treating substance, preferably the catalyst granules, is used. In addition, it has an easy flow, so that due to the
- the water-treating substance preferably the catalyst granules
- the protective lime crystals can be distributed throughout the storage.
- a preferred embodiment provides that the water heater, a boiler and the treatment unit are arranged such that water, preferably heated to at least 50 ° C., flows through them, which has been heated by the heating element.
- the treatment unit is arranged in the immediate vicinity - preferably above - the heating element.
- the device according to the invention can also be designed in such a way that it can be used in water heaters, e.g. Water boilers or coffee machines can be used and there e.g. prevents calcification of the water heater efficiently.
- water heaters e.g. Water boilers or coffee machines can be used and there e.g. prevents calcification of the water heater efficiently.
- Another embodiment of the invention provides that the water-treating substance, preferably the catalyst granulate, in a suitable ⁇ W 1 * M ⁇ ⁇
- the washing water flows through the granules several times and in the case of
- Lime treatment can be well enriched with lime crystals.
- the lime crystals also have the effect of reducing the
- a particularly preferred embodiment of the device according to the invention provides that the treatment unit is a unit for reducing limestone formation.
- a variant provides that nuclei are released into the surrounding water by the device according to the invention.
- the water-treating substance of the treatment device - preferably the catalyst granulate - is not consumed.
- a preferred embodiment variant provides that the water-treating substance of the treatment device, preferably the catalyst granulate, can be regenerated.
- the water-treating substance preferably in granular form
- a weakly acidic ion exchange material as well as a method and a device for converting a preferably weakly acidic ion exchange material from the H form to the Ca form is known from the Austrian patent AT 407 843 B.
- Fig. 6 an inventive integration of a treatment unit in a
- Fig. 1 shows the integration of a water treatment unit in a wall-mounted
- the catalyst granulate 5 is preferably enclosed in an annular cylindrical container 6, the walls of which are formed from a filter fabric or a slit or perforated mask.
- the thickness of the ring cylinder 6 should not exceed 1 cm in order not to hinder the water transport through the catalyst granules.
- the ring cylinder 6 is best attached to the heating flange 9 in such a way that the radiators 4 are enclosed by the ring cylinder. Alternatively, the ring cylinder 6 can be clamped to the one in the boiler 8
- Hot water supply line 3 (surrounding the radiator or immediately above the radiator).
- FIG. 2 shows a variant in which the water treatment unit 11 is designed as a flow tube above the electric heating element 4.
- cold water enters through the inlet openings 10 at the lower end of the flow tube 11 and is heated on the heating elements 4 and then rises upwards over the granulate bed.
- the water is mixed by the convection roller and pressed down again, so that the water to be treated flows several times past the catalyst granulate 5.
- 3 and 4 show analogous exemplary embodiments for commercially available free-standing boiler variants with internal heat exchangers.
- Fig. 5 shows the use of catalyst granules 5 in a memory with a spiral heat exchanger. For this situation it is advisable to hang a special filter basket 12 with catalyst granulate 5 in the area between the heating lines.
- the filter basket 12 can, for example, again be designed as a ring cylinder.
- FIGS. 1 to 5 show different designs of containers for holding the water-treating substance, preferably the Catalyst granules, which are installed in the storage water heater.
- the actual purpose of the technical system is to heat and store the
- Catalyst technology shown. Here the catalyst granulate 5 is integrated directly into the heating. In most coffee machines, the heating is in the form of an externally heated (bent) tube 14. For most common coffee machines, about 10 ml of catalyst granules 5 are sufficient.
- Heating pipe 14 The granules 5 is 13.3 by means of a filter piece
- Industrial water side can be filled with the catalyst granulate.
- the actual purpose of the instantaneous water heater is to heat the liquid and to transfer it.
- the continuous-flow heater or the plate heat exchanger must have sufficient heating power to provide the required hot water in the required time.
- the purpose of the heating output is therefore not like e.g. in the Fig.
- the technical design requires certain necessary adaptation to the continuous flow heater or plate heat exchanger in order to keep the water-treating substance, preferably the catalyst granulate, in the area provided for this.
- the treatment unit can also treat the drinking water in another way, in particular in order to avoid or reduce the formation of limestone.
- suitable water-treating substances are regenerable ion exchangers or catalytically active polymers.
