Definitions

  • the invention relates to a method and an arrangement for improving the quality of water taken from a conventional water supply network and intended for drinking and / or use in households, companies or the like.
  • the invention provides for the method according to claim 1 to be developed further in accordance with the teaching of the method according to claim 2.
  • a central impregnation of the water directed to the various points of use and removal is sought and achieved in order to ensure an extraordinarily efficient and reliable CO 2 enrichment with the help of commercially available and larger CO 2 containers.
  • This central impregnation ensures that the minerals and trace elements still contained in the water taken from the supply network remain dissolved in the water, so that the risk of solid deposits in the pipes and devices and machines is largely reduced and for the health of the Minerals beneficial to humans for the human organism continue to be available.
  • control can take place according to the teaching of claims 3 to 6.
  • the measures of the invention largely restore the original natural content of CO and H 2 CO 3 in the water taken from the ground after the natural content is reduced to a very low value by the intervention of the waterworks.
  • the minerals still contained in the water taken from the supply network are also kept in solution and their deposition in the form of solid compounds is excluded.
  • the minerals remaining in solution are also available to biological organisms. available to human organisms and are urgently needed by them.
  • the invention can advantageously be further developed in that, at removal points which are provided for drinking or medical treatment purposes, the impregnation device is followed by a metering device for minerals, in particular for magnesium and / or calcium.
  • a metering device for minerals in particular for magnesium and / or calcium.
  • the control can preferably take place as a function of temperature, it being assumed that the water required for medical purposes or for washing and dishwashing purposes is once at temperatures up to about 60 ° C. and also at tem temperatures are used approximately according to the temperature of the water in the supply network. Thanks to the temperature-dependent control, the maximum degree of impregnation in cold water and thus the maximum solubility for minerals and the maximum protection against deposits of solids in machines can be exploited, while on the other hand an extremely economical use of Co 2 is possible at elevated temperatures.
  • the drawing shows a schematic representation, partly in section, of an arrangement for carrying out the new method in one embodiment.
  • the water to be mixed with CO 2 and H 2 C0 3 is taken from the general supply network at 36.
  • This can be, for example, the domestic water connection to the supply network, which is equipped in the usual way with blocking elements, water meters, etc.
  • a separate quantity counter 42 can be provided behind these devices in order to be able to set the total quantity of water removed in relation to partial quantities more easily.
  • a line 35 is branched off behind the quantity counter 42.
  • This can be assigned a shut-off valve 40 and in front of it a partial quantity counter 39 and a controllable throttle device, such as an adjustable pressure reducer 38.
  • the pointer line leads, as shown at 1, via a check valve 2 to the inlet 14 of a device 13 with which the partial water quantity flowing through the branch line 35, 1 is finely impregnated with C0 2 in almost maximum concentration to form H Z C0 3 .
  • the device 13 comprises a system of a plurality of injection nozzles connected in series, which are arranged coaxially or coaxially with the connection 14 of the branch line 35.
  • the nozzles each have injection openings which, in the example shown, are in free flow communication with an annular gas chamber 19.
  • Each nozzle has an abruptly enlarged cross-section at the level of the injection openings, the cross-sectional enlargements increasing in the flow direction from nozzle to nozzle. at the cross-sectional enlargements, the flow rate of the water supplied via the connection 14 is abruptly reduced and an underpressure is currently being generated, which is used as suction pressure. The pressure is equalized up to the next injector nozzle and until then gas and water are mixed.
  • the successive nozzles are divided into two nozzle sets 15 and 16.
  • the nozzle set 15 has three nozzles, the injection suction openings of which are in flow connection with the gas space 19.
  • the nozzle set 16 has two successive nozzles, the injection suction openings of which are connected to an annular chamber 23, which in turn extends downstream of the last cross-section tion with the outflow part 17 of the device 13 are in free flow connection.
  • the gas space 19 is connected via a line 20 to a pressure reducer 21, for example a valve or a slide, which connects the device via a check valve 11 to the pressure reducing valve 9 and the pressure display device 10 of a C0 2 compressed gas bottle 8.
  • a pressure reducer 21 for example a valve or a slide, which connects the device via a check valve 11 to the pressure reducing valve 9 and the pressure display device 10 of a C0 2 compressed gas bottle 8.
  • This is a normal bottle of conventional and commercial size, which can be set up in the garage or in the basement near the water connection 36 of the household or small business. This can be a normal bottle with a capacity of around 6 kg.
  • the device 13 is inserted into the head part of a container 3, which has an upper gas head space 5 and a lower water filling space 4, into which the water via the branch line 35, 1 and the device 13 after the fine impregnation with C0 2 and enrichment of H 2 C0 3 flows.
  • the water level is controlled via water level electrodes 6, 7 or equivalent devices.
  • the mouth of the outlet 17 of the device 13 is below the lowest water level, so that the emerging impregnated water flows into the water reservoir 4. Any larger bubbles that are present can still rise upwards into the head space in the water reservoir 4.
  • the head space itself is connected via a branch line 12 to the connection for the gas bottle 8, namely between the check valve 11 and the pressure reducer 21.
  • the gas pressure in the head space 5 can thus differ from the gas pressure in the gas chamber 19, the pressure in the gas space 19 is adapted to the pressure in the branch line 35, 1, while the pressure in the head space 5 can also be used as a delivery pressure for the water.
  • a displacement body 22 can be arranged concentrically in the nozzle sets.
  • an outlet 17 projects downward into the water reservoir 4.
  • An outlet 24 can be provided in the bottom of the container 3 offset from this outlet. The displacement should ensure that any larger bubbles 18 can rise in the impregnated water at rest and are not carried away to the outlet 24.
  • An idle protection 25 is assigned to the outlet 24.
  • the outlet line branches behind this in branch lines 64 and 67.
  • a metering device 65 or 68 is assigned to each branch line. Behind the dosing device, the branch line at 66 or 69 leads into sub-lines 62 or 54 of the water supply of the household or small business. It is assumed that the line 54 is the usual household supply line from which drinking water and process water as well as water for the various household machines and the like are taken.
  • the water for a domestic beverage dispenser 52 can also be removed via a branch line 53, which is either designed as a coffee machine or, as in the example shown, for the production of C0 2 -impregnated drinks and has a carbonator for this purpose.
  • the CO 2 supply to the carbonator takes place via a branch line 50, which is connected to the same compressed gas bottle 8, 9 as the device 13 via a check valve 51.
  • the second line 62 is provided as a irrigation water line, as is provided in many households and for hobby gardeners with an external connection for watering purposes in the garden or household.
  • the lei can also be used if necessary device an additional pump 63 may be provided.
  • Each of the two lines 54, 62 is connected via a check valve 60, a partial quantity counter 59 and adjustable pressure reducers 58 to a branch 56, 57 of the common supply line, from which the branch line 35, 1 branches off to supply the device 13.
  • the amounts of water flowing through the various lines 35, 54 and 62 can be adjusted by setting the appropriate pressure reducers, such as valves or slides. It can also be seen that from the same device 13, 3 the two different lines 54, 62 can be mixed independently of one another to different degrees with C 02 and H 2 C0 3 .
  • the metering devices 65 and 68 are used to control the different concentrations.
  • the different concentration is desirable since only a relatively low concentration of Co 2 and H 2 CO 3 is required for the purposes of use and drinking, while for the supply of plants in the house and Garden as high a concentration as possible is desirable. This high level of concentration contributes significantly to maintaining good health and growth, and to promoting earnings, as detailed studies have shown.
  • the reunited subsets of water require a certain path to complete mixing.
  • Characterized is in the lines 54 and 62 with C0 2 impregnated water without bubbles, so that this water maintains its impregnation state with extremely high stability, the C0 2 and the H 2 CO 3 formed with it to a large extent when poured with the water can penetrate the soil and remains largely in the household until it is immediately consumed or drunk in water. At the same time, the CO 2 consumption to achieve predetermined concentrations in lines 54 and 62 is kept extremely low.
  • the content of CO 2 and H 2 CO 3 significantly increases the solubility of minerals and trace elements in water. Existing minerals in solution water and drinking water remain in solution for a much longer time and can accumulate much less in equipment and machines. The dissolved minerals and trace elements also benefit the human organism almost completely, whereby the content of CO and H 2 CO 3 significantly promotes the body's absorption capacity for such minerals.
  • the concentration of C0 2 and H 2 CO 3 in the drinking and industrial water of a household as well as the concentration in the irrigation water is controlled depending on the nature of the water in the supply network.
  • the water connection 36 or the branch line 35 can be assigned measuring devices 70 which, for example, measure the pH and / or the electrical conductivity of the water.
  • the measured values of the sensor 70 are fed via line 71 to a control unit 72, which controls the two metering devices 65 and 68 individually according to a predetermined program as a function of the measured values via lines 73 and 74. In this way, the optimal concentrations can be reliably set and maintained, even if the nature of the water should change.
  • the maximum impregnation with CO 2 prevents the deposition of solids in the machines and, in conjunction with a metering device for mineral salts downstream of the device, ensures optimal enrichment of the impregnated water with such minerals in the medical or hygienic field.
  • a second impregnation stage provides for impregnation up to the maximum absorption capacity of the water at the increased use temperature in the machines or for medical or hygienic purposes. In most washing machines and dishwashers, only temperatures up to a maximum of about 60 ° C are measured turns. An impregnation taking this temperature into account ensures an increased CO 2 content in the heated water as well as the extremely economical use of CO 2 , since an expulsion of CO 2 is prevented or reduced when the water is heated due to the selected impregnation level.
  • the impregnation levels can be controlled automatically depending on the temperature. However, depending on the switching of e.g. Depending on the program, the washing process follows the rinsing process or the like.
