Definitions

  • the invention relates to a process for the treatment of irrigation water by enrichment with C0 2 and H 2 C0 3 , in which in the through a line with the pressure and temperature approximately equal to those flowing in a conventional water supply line continuously pressurized CO 2 gas is introduced, as well as an arrangement for carrying out the method, which has an elongated, straight flow channel section which is connected at one end to a pressure source for irrigation water and at the other end to a pouring system or a collecting container and which connects to an impregnation zone with a circumferential connection has a C0 2 pressure gas source.
  • DE-PS 866 341 describes an arrangement for introducing C0 2 into the pressurized water supply line of an irrigation system.
  • An injector is mentioned as a means of introducing C0 2 without this being described in detail.
  • Such an injector system is shown in FR-PS-1 171 059.
  • This has a straight flow section through which one of the two media to be mixed flows.
  • several short pipe sections are arranged consecutively with increasing diameter, the ends of which are overlapped to form an annular gap.
  • the pipe section of the largest diameter is designed with respect to the straight channel so that this also forms an annular gap with the channel.
  • the flow in the channel is thus continuously divided into several partial flows.
  • a device for supplying the second of the media to be mixed is provided centrally on the inlet side of the tube section of smallest diameter, which device introduces this second medium into the flow in a finely distributed manner, e.g. B. sprayed.
  • This is a system in which turbulence that promotes the mixture is generated in a straight flow channel of constant cross-section by a flow control system of several differently dimensioned pipe sections, into which the second medium is injected or sprayed on the inlet side.
  • DE-OS-3 117 797 a device for enriching aquarium water with carbon dioxide is shown and described, in which a C0 2 gas zone is provided in a device through which the aquarium water is passed in a swirled form.
  • the water feed line z. B. a washing machine a metering device to add an additive, for. B. automatically initiate a water softener.
  • the flow velocity of the water is changed by the formation of a nozzle or a gradual change in the flow cross section.
  • a line for the additive opens into a mixing chamber area.
  • several holes are provided which are open to the atmosphere and through which small amounts of air can be drawn in. These vents have the purpose when the water supply to the household machine, e.g. B. washing machine, is switched off to prevent a vacuum in the supply line for the water, through which with the additive, for. B. the softener mixed water from the mixing chamber area is sucked back into the water supply.
  • the line section in front of the mixing chamber area should therefore be ventilated by the air sucked in through the bores, and the vacuum that may be present there should be eliminated.
  • the invention relates to a method for treating irrigation water by enrichment with C0 2 and H 2 C0 3 .
  • irrigation water is often required in large quantities in glasshouses and garden centers as well as in agriculture, which also requires corresponding amounts of CO 2 if impregnation is desired.
  • the impregnated irrigation water is applied to the plant crops, the water, which is usually applied under pressure, is released to atmospheric pressure.
  • C0 2 impregnated water amounts of CO 2 gas, the lost.
  • considerable proportions of the gas in the water are present in relatively large bubbles.
  • the invention has for its object the method specified at the outset and the arrangement used to carry out the method to further develop in such a way that a much more precise metering of the amounts of C0 2 gas and H 2 C0 3 supplied to the plants and the soil with the water is possible and the liquid is so impregnated with C0 2 that disturbances from larger bubbles in the liquid are not to be feared and C0 2 losses when applying the irrigation water are largely avoided, so that the treatment of cultures with C0 2 - impregnated liquid even on a large scale, eg. B. nurseries or farms can be used in an economical manner.
  • the water is impregnated with C0 2
  • the liquid is impregnated very fine, ie free of larger bubbles.
  • the CO 2 gas in the liquid is so small and so finely divided that the expansion of the liquid during the application, e.g. B. when spraying or raining, gas losses occurring are very low. So that the impregnated with C0 2 gas liquid even in large quantities, for. B. economically in horticultural companies or in agriculture.
  • the proportion of CO 2 gas and H 2 CO 3 supplied to the plants or the soil can also be determined much more precisely, since there is no significant risk of impairments due to uncontrollable gas losses during the application.
  • the liquid impregnated in this way is largely free of disruptive bubbles, so that it can be applied reliably and without interference even by capillary delivery systems.
  • Normal CO 2 absorption capacity is understood to mean the absorption capacity of normal, ie not chemically pure, water.
  • the new process enables irrigation water to be treated in a way that approximates the conditions that occur in a particularly optimal form in nature in the areas of the earth close to the roots.
  • the required negative pressure is generated by the root system as such and the C0 2 is partially emitted by the root system itself or made available as soil-based C0 2 , the C0 2 in gaseous form at approximately atmospheric pressure and atmosphere Temperature is present.
  • a further measure, which substantially supports the fine impregnation and promotes the homogeneous mixing of the liquid, is that the gas impregnation zones are followed by further flow channel sections with shoulder-like extensions and underlying bores, which are used for the back-mixing of already completely impregnated liquid with the liquid flowing through the flow channel.
  • the new arrangement can be used to feed the impregnated liquid directly to a tapping point or consumer point so that the impregnated liquid can be dispensed directly.
  • a supply pressure container in which a supply of finely impregnated liquid is kept ready, the inflow of the liquid taking place through the arrangement according to the invention and the outflow from the liquid supply on the other hand, it is shielded or offset so that any relatively large bubbles present have sufficient time to rise upwards into the gas space in the liquid supply.
  • the pressure vessel 1 consists of a pressure jacket 2 and cover 3 and bottom 4.
  • a liquid quantity 8 between the minimum fluid level 26 and the maximum fluid level 27 is maintained in the pressure vessel by the sensors shown.
  • a head space 7 remains above the liquid, which through line 5 with the carbon dioxide gas, under a predetermined pressure of z. B. is kept filled up to 6 bar.
  • the gas is supplied, for. B. via a pressure sensor. a pressure reducer.
  • a drain 6 for the impregnated liquid from the liquid supply 8 is provided in the bottom of the container 4.
  • An impregnation system 9, which is built into the cover 3, is arranged offset in the horizontal direction with respect to the outlet 6.
  • the system 9 has a central throughflow channel, which is connected on the inlet side to a source of pressurized water via a connector 10.
  • the system 9 can e.g. B. sealed by means of flange 11 in the cover 3.
  • the impregnation system 9 has impregnation zones 12a, 12b, 12c lying one behind the other in the flow direction. Before each impregnation zone, the clear width of the liquid flow channel is widened in steps, as shown at 13a, 13b, 13c. As a result, the flow velocity of the liquid changes suddenly as it enters an impregnation zone.
  • the impregnation system 9 is followed by a further channel section 15 axially.
  • this has two backmixing zones 16a, 16b.
  • the clear width of the liquid flow channel is changed abruptly before entering a backmixing area to promote mixing.
  • These backmixing areas 16a, 16b serve to promote mixing and homogenization and to reduce the proportion of larger bubbles.
  • the system 15 has an outer jacket 18, closed off from the gas space 7, the lower open edge of which ends below the lowest liquid level 26 in the amount of liquid 8.
  • the lateral displacement of the outlet 25 of the system 15 relative to the outlet 6 of the liquid supply ensures that any larger bubbles in the liquid have enough time to rise through the liquid supply 8 into the head space 7, so that they do not pass through the liquid withdrawal and thus through the line 6 can be carried away.
  • the liquid takes up gas from the head space 7 in the manner described.
  • the liquid keitador 26 rises due to the liquid supplied.
  • the head space 7 is reduced in volume. If this reduction in volume is greater than the gas absorption of the liquid, the pressure in the head space 7 increases at the same time, so that the gas supply via the supply line 5 is switched off. If the gas absorption by the liquid is greater, gas continues to be fed into the head space 7 during the impregnation, so that the pressure is maintained in this space.
  • the pressure in the gas space can, for example, on the line pressure of the irrigation network, z. B. at a pressure up to 6 bar or above.
  • the pressure vessel 1 is omitted.
  • the impregnation system 9 is surrounded by a jacket, the annular space of which is connected to the pressurized gas source, while the jacket 18 of the backmixing system 15 at the lower end, as indicated at 22, remains closed. In this case, the flow channel for the liquid continues, as indicated at 6a, to the point of withdrawal.
  • the difference between the smallest and the largest liquid level 26 or 27 is such that when liquid is removed individually from the pressure vessel 1, the supply of liquid through the systems 9 and 15 is not too frequent, so that a pump supplying the liquid to the inlet 10 is not constantly on - and needs to be switched off.
  • the flow cross-section for systems 9 and 15 is significantly increased.
  • a displacement body 30 in the systems 9 and 15, which displaces the liquid in an annular flow through the system.
  • the displacement body 30 could be gradually or stepwise enlarged in diameter or could also be designed as a smooth cylinder body in the direction of flow.
  • the cross-sectional shape and cross-sectional change of the body 30 depends on the volume to be enforced and must ensure that the desired abrupt change in speed of the liquid is achieved from the impregnation zone to the impregnation zone.
  • the arrangement described works reliably both for direct dispensing and for the depicted indirect dispensing of impregnated liquid, namely in a pressure range of approximately 1 bar upwards.
  • the arrangement is therefore particularly suitable for use in horticultural businesses, agriculture and forestry since it can be used for all pressure conditions which occur there, since any compression of the gas in water which is disadvantageous in practice is avoided because of the reduced impregnation pressure.
  • the C0 2 gas pressure is the same as the output pressure.
