DEVICE FOR DISINFECTING A LIQUID

Description

Field of the invention

[0001] The present invention relates to a device for disinfecting a liquid having a rotationally symmetrical reaction chamber and the disinfection of a liquid, such as water, as it flows through the device. State of the art

[0002] Liquids intended for human or animal consumption typically require treatment. Such liquids must be disinfected. Water, in particular, must be sufficiently disinfected before consumption or other uses, such as personal hygiene. Among the germs to be combated are, in particular, Legionella. Thermal, chemical, and electrochemical disinfection processes for reducing the number of germs, such as Legionella, are known in the state of the art. However, these processes are costly and / or structurally complex and do not guarantee a sustainable, sufficient reduction of germs in drinking water.

[0011] DE 10 2006 045 773 A1 discloses a water treatment system comprising a reaction tank and a cavitation device connected thereto. Water is fed from the reaction tank into the cavitation device, which is fluidically designed such that relatively large pressure differences occur in the flowing water, forming cavities in the water that are filled with gas components previously dissolved in the fluid, such as oxygen and carbon dioxide. This cavitation thus removes nutrients from the water for the germs. The water treated in this way is returned to the reaction tank, which is designed for a high separation rate of the gas components, thus providing water that is low in nutrients for germs. However, the overall structure of the system is very complex, and it is questionable whether sufficient germ reduction can be achieved through the nutrient deficiency achieved through cavitation alone.

[0012] EP 1 294 474 B1 discloses a device for the physico-chemical treatment of liquids. A downward cyclonic flow of an introduced liquid is generated within the cavity, intensifying chemical reactions and mechanically destroying microorganisms. The flow is redirected upward through a vertical riser tube and discharged from the cavity at the top. The design of the device is relatively complex, and the formation of the cyclonic flow and thus the efficiency of germ reduction can be problematic.

[0013] It is therefore an object of the present invention to provide a device for disinfecting a liquid, in particular for disinfecting water, in which the above-mentioned problems of the prior art are overcome or at least mitigated. Description of the invention

[0014] The above-mentioned object is achieved by providing a device for disinfecting a liquid, for example water, according to patent claim 1. This device comprises a reaction chamber rotationally symmetrical about its longitudinal axis, having a head region (upper region) and an (opposite) bottom region (lower region) and an intermediate region between the head region and the bottom region;

[0015] a first inlet connected in the head region to the reaction chamber for introducing a first component (a first portion) of the liquid into the reaction chamber, and a second inlet connected in the head region to the reaction chamber for introducing a second component (a second portion) of the liquid, different from the first component, into the reaction chamber; and an outlet connected to the reaction chamber in the bottom region for discharging the liquid (downward) from the reaction chamber; wherein the first inlet and the second inlet are arranged and the reaction chamber is designed (geometrically) such that a three-dimensional (turbulent) vortex flow is generated in the liquid within the reaction chamber over a large part of the volume of the reaction chamber, for example at least 50% or 60% of the volume (of the cavity) of the reaction chamber. According to the invention, the radius of the rotationally symmetrical reaction chamber changes in the intermediate region according to a clothoid.

[0016] In such a three-dimensional vortex flow, germs present in the liquid are reliably destroyed by the mechanical forces acting within the flow. Local cavitation can also occur, which can contribute to reducing the number of microorganisms.

[0017] Furthermore, desired chemical reactions, such as oxidation and reduction, can be enhanced by the three-dimensional vortex flow. Chemical reactants can be additionally supplied to the reaction chamber via a suitable supply line or transported along with the introduced liquid. The treatment of the liquid in the device can also lead to a local change in the viscosity and / or surface tension of the liquid.

[0018] The three-dimensional vortex flow has a macroscopic velocity component directed from the top of the reaction chamber to the bottom, i.e., from top to bottom. During operation, the device, and thus the reaction chamber, will generally be oriented perpendicular to an installation floor (although the invention is not limited thereto), and thus, the terms "top" and "bottom" are used here and below to indicate positions that are further or closer to the Earth's center of gravity, respectively. In particular, "top" is closer to the top of the reaction chamber than "bottom."

[0019] The three-dimensional vortex flow can develop very strongly in the device according to the invention, and the liquid can leave the reaction chamber freely and without significant deflection (in particular, without significant deflection toward the head region). No additional circulation pumps or similar devices are required to generate the three-dimensional vortex flow (although pumps can be provided to deliver the liquid to the first and second inlets).

[0020] The first and second inlets can be routed through the outer surface of the reaction chamber, which is rotationally symmetrical about its longitudinal axis, or they can be routed through the end face (the lid) in the head region of the reaction chamber, or they can be connected to a common inlet routed through the end face in the head region. In particular, the first and second inlets can be designed as branches of a common inlet.

[0021] The head region of the reaction chamber can have a larger radius than the largest radius of the intermediate region. In particular, the shape of the reaction chamber is not heart-shaped. The head region can have an outwardly concave region (so that it extends into the cavity of the reaction chamber in this region) or a flat region in its upper region. The head region can therefore be flattened in its upper region, opposite the intermediate region of the reaction chamber. According to the invention, the intermediate region of the reaction chamber changes according to a clothoid.This means that the projection of the lateral surface of the reaction chamber onto a plane perpendicular to the cross-sectional area in this intermediate region represents a curve whose curvature K increases with the arc length L (from a fixed starting point of the curve to the respective curve point considered): K = 1 / R = L / A 2< with the radius of curvature R and the clothoid parameter A. The lateral surface therefore has such a curve in the intermediate region, so that the radius of the reaction chamber in this region changes according to a clothoid.

[0022] Furthermore, according to a further development, the radius in the bottom region of the reaction chamber (and possibly in contrast to the intermediate region) does not change according to a clothoid. For example, the radius in the bottom region can asymptotically approach an axis parallel to the longitudinal axis.

[0023] Experiments and numerical calculations have shown that the above-mentioned geometric features of the reaction chamber promote the formation of a strong three-dimensional vortex flow.

[0024] According to a further development of the device, in the examples described above, the first inlet has a first inlet opening within the reaction chamber in a first plane perpendicular to the longitudinal axis of the reaction chamber, and the second inlet has a second inlet opening within the reaction chamber in the first plane or in a second plane different from the first plane perpendicular to the longitudinal axis of the reaction chamber (the first and second planes therefore each encompass a cross-sectional area of ​​the reaction chamber). The liquid enters the reaction chamber from the inlet openings, wherein the inlet openings may have nozzles or may be designed as nozzles.

[0025] The inlet openings are oriented such that the liquid enters the reaction chamber essentially in the direction of the outer surface of the reaction chamber. The inlet openings can be directed by several degrees (e.g., 1 to 10 degrees) out of the horizontal plane (cross-sectional area of ​​the reaction chamber) toward the outlet. According to one example, the above-mentioned first plane and / or second plane is formed in a region of the largest radius of the reaction chamber. Thus, the first or second plane can encompass the cross-sectional area of ​​the reactor chamber at which the radius of the reactor chamber is largest.

[0026] In this case, the first inlet opening can be spaced from the outer surface of the reaction chamber by more than 1 / 20, 1 / 10, or 1 / 5 of the radius of the reaction chamber in the first plane, and the second inlet opening can be spaced from the outer surface of the reaction chamber by more than 1 / 20, 1 / 10, or 1 / 5 of the radius of the reaction chamber in the first or second plane. In particular, the inlet here is not directly tangential to the inner surface of the jacket of the reaction chamber. This allows higher velocities and turbulences to be achieved compared to tangential supply of the liquid. This also intensifies the formation of a three-dimensional vortex flow in the liquid to be treated.Such reinforcement can also be achieved by arranging the second inlet opening in a direction opposite to the direction of the first inlet opening, so that the liquid enters the reaction chamber in two opposite directions, each towards the outer surface of the reaction chamber.

[0027] According to a further development, the reaction chamber comprises a third and a fourth inlet, wherein the third inlet has a third inlet opening within the reaction chamber in a third plane perpendicular to the longitudinal axis of the reaction chamber, and the fourth inlet has a fourth inlet opening within the reaction chamber in the third plane or in a fourth plane different from the third plane perpendicular to the longitudinal axis of the reaction chamber. The third and / or fourth planes can be the same as or different from the aforementioned first or second plane.

[0028] According to this development, the liquid also enters the reaction chamber from the third and fourth inlet openings (in the form of a third and fourth component thereof), wherein the third and fourth inlet openings can also have nozzles or can be designed as nozzles. The third and fourth inlet openings are also aligned such that the liquid enters the reaction chamber essentially in the direction of the lateral surface of the reaction chamber. The third and fourth inlet openings can also be directed by a few degrees (for example 1 to 10 degrees) out of the horizontal plane in the direction of the outlet. According to one example, the above-mentioned third plane and / or fourth plane is formed in a region of the largest radius of the reaction chamber.

[0029] In this case, the third inlet opening can be spaced from the outer surface of the reaction chamber by more than 1 / 20, 1 / 10, or 1 / 5 of the radius of the reaction chamber in the third plane, and the fourth inlet opening can be spaced from the outer surface of the reaction chamber by more than 1 / 20, 1 / 10, or 1 / 5 of the radius of the reaction chamber in the fourth plane. This also intensifies the formation of a three-dimensional vortex flow in the liquid to be treated. Such an enhancement can also be achieved by arranging the fourth inlet opening in a direction opposite to the direction of the third inlet opening, so that the liquid enters the reaction chamber in two opposite directions towards the outer surface of the reaction chamber.

[0030] The third inlet can be arranged in the circumferential direction of the reaction chamber between the first and second inlets, and the fourth inlet can be arranged in the circumferential direction of the reaction chamber between the first and second inlets. In particular, in this development, which comprises the four inlets arranged in this way, the respective directions of adjacent inlet openings can be offset by 90° from one another. Furthermore, the third and fourth inlets can be designed as further branches of an inlet common to the first and second inlets. The first and second inlets can be connected to the common inlet, which can be guided through the end face of the reaction chamber in the head region, and the third and fourth inlets can be guided through the lateral surface of the reaction chamber.

[0031] The first, second, third and fourth inlets can be guided through the outer surface of the reaction chamber.

[0032] At least some of the inlets mentioned in the examples described above and below can be designed as openings / bores ("intakes") through the shell of the reaction chamber. The profile of the openings / bores can be designed such that the liquid enters the reaction chamber through them non-tangentially to the shell surface. For example, the profile can be designed to be asymmetrical (not rotationally symmetrical) with respect to the longitudinal axis of the openings / bores.

[0033] According to a further development, for example, the first, second, third and fourth inlets are guided through the outer surface of the reaction chamber, and the reaction chamber has a fifth and sixth inlet, wherein the fifth and sixth inlets are connected to an inlet which is guided through the end surface of the reaction chamber in the head region.

[0034] The fifth inlet has a fifth inlet opening within the reaction chamber in a fifth plane perpendicular to the longitudinal axis of the reaction chamber, and the sixth inlet has a sixth inlet opening within the reaction chamber in the fifth plane or in a sixth plane different from the fifth plane perpendicular to the longitudinal axis of the reaction chamber. The fifth and / or sixth planes may be different from the above-mentioned first and / or second planes and, in particular, may be closer to the bottom region of the reaction chamber than the first and / or second planes.

[0035] According to this development, the liquid also enters the reaction chamber from the fifth and sixth inlet openings, whereby the fifth and sixth inlet openings can also have nozzles or be designed as nozzles. The fifth and sixth inlet openings are also aligned such that the liquid enters the reaction chamber essentially in the direction of the lateral surface of the reaction chamber. The fifth and sixth inlet openings can also be directed by a few degrees out of the horizontal plane in the direction of the outlet. According to one example, the aforementioned fifth plane and / or sixth plane is also formed in a region of the largest radius of the reaction chamber.

[0036] In this case, the fifth inlet opening can be spaced from the outer surface of the reaction chamber by more than 1 / 20, 1 / 10, or 1 / 5 of the radius of the reaction chamber in the fifth plane, and the sixth inlet opening can be spaced from the outer surface of the reaction chamber by more than 1 / 20, 1 / 10, or 1 / 5 of the radius of the reaction chamber in the sixth plane. This also intensifies the formation of a three-dimensional vortex flow in the liquid to be treated. Such an enhancement can also be achieved by arranging the sixth inlet opening in a direction opposite to the direction of the fifth inlet opening, so that the liquid enters the reaction chamber in two opposite directions towards the outer surface of the reaction chamber.

[0037] At least some of the inlets mentioned in the examples described above, in particular the inlets leading through the jacket of the reaction chamber, can be equipped with valves by means of which the flow of liquid into the reaction chamber can be regulated or controlled.

[0038] Furthermore, in all of the above-described examples of the device according to the invention, it is not necessary to provide any additional deflection means (internal components) for deflecting the liquid within the reaction chamber, in particular devices for deflecting the liquid from the bottom region of the reaction chamber toward the head region of the reaction chamber. Rather, a relatively free outflow of the liquid from the reaction chamber through the drain downwards is permitted. This allows for a lower back pressure to build up within the reaction chamber to achieve the desired flow characteristics than if such deflection means and a discharge of the liquid from the head region of the reaction chamber were provided.

[0039] Also provided herein is a method for disinfecting a liquid (e.g., water) according to claim 12. The method comprises the steps: Providing a device according to one of the preceding claims; introducing the liquid into the provided device; passing the liquid through the provided device and forming a three-dimensional vortex flow in the liquid within the reaction chamber; and discharging the liquid from the provided device.

[0040] Disinfection can be achieved by destroying microorganisms, such as Legionella, in the three-dimensional vortex flow. The treatment of the liquid in the device can also lead to a local change in the viscosity and / or surface tension of the liquid and to the enhancement of chemical activities (e.g., after the addition of additional chemical reactants). The treatment of the liquid can be repeated in the reaction chamber. Thus, the method can further comprise repeatedly introducing the liquid discharged from the provided device into the provided device.

[0041] The method mentioned can be used, in particular, to kill Legionella bacteria in water (e.g., drinking water or domestic water). Thus, the method of one of the examples described above can further comprise connecting the provided device to a drinking water or domestic water network for introducing the liquid into the provided device, wherein the disinfection can, in particular, comprise reducing the number of Legionella bacteria contained in the water. The water can be supplied to the device via pumps connected to the drinking water or domestic water network. In particular, the device can be integrated into the hot water circulation system of a building.

[0042] Embodiments of a device according to the invention are described below with reference to the drawings. The described embodiments are to be considered in all respects merely illustrative and not restrictive, and various combinations of the stated features are included in the invention. Figure 1 illustrates in longitudinal section a device for treating a liquid with a rotationally symmetric reaction chamber according to an embodiment of the present invention. Figure 2 shows a cross section of the Figure 1 device shown. Figure 3 illustrates in longitudinal section a device for treating a liquid with a rotationally symmetric reaction chamber according to another embodiment of the present invention. Figure 4 shows a cross section of a device according to an embodiment of the present invention.

[0043] A device for disinfecting a liquid is provided herein. The liquid, in particular water, is disinfected in the device. Disinfection occurs by destroying microorganisms, in particular Legionella, in the three-dimensional vortex flow occurring in the reaction chamber of the device, which can in particular have a finite vortex strength ω = rot v with the velocity field v of the liquid. The vortex flow has velocity components in all three directions of the Cartesian coordinate system. In general, the vortex flow will have highly turbulent components. In this vortex flow, the microorganisms are destroyed, for example, due to the resulting thrust and shear forces / stresses and pressure differences. For example, turbulent boundary layers with large velocity gradients can form, in which microorganisms can be destroyed.Cavitation can also occur locally in the reaction chamber, which can contribute to reducing the number of microorganisms.

[0044] An embodiment of the present invention is described in the Figures 1 and 2illustrated. The device 100 shown for disinfecting a liquid comprises a reaction chamber 101 that is rotationally symmetrical about its longitudinal axis 116 and has a lateral surface 102. In the example shown, the reaction chamber 101 is formed as a hollow space using an upper component 103 and a lower component 104. The upper and lower components (103, 104) can have an outer cylindrical shape and can, for example, be milled stainless steel components. Between the upper component 103 and the lower component 104, an inner sealing groove 111, for example with a sealing ring, and an outer sealing groove 112, also for example with a sealing ring, are provided. The upper component 103 and the lower component 104 can be joined and held together using clamping screws 113.

[0045] An inlet 106 with a pipe connection 114 is connected to the head region KB of the reaction chamber 101 and is guided axially into the reaction chamber 101. An outlet 107 with a pipe connection 115 is provided in the bottom region BB of the reaction chamber 101. A liquid to be treated flows through a splitter 108 of the inlet 106 into a first inlet 117 and a second inlet 118. The first inlet 117 has a first inlet opening 109, and the second inlet 118 has a second inlet opening 110. The first and second inlet openings 109, 110 can be designed as nozzles or comprise nozzles.

[0046] How it turns out Figure 2 , which shows a cross-section of Figure 1As can be seen from the configuration shown, the inlets 117 and 118 are oriented such that they discharge the liquid to be treated radially spaced from the outer surface 102 of the reaction chamber 101 in opposite directions toward the outer surface 102. The inlets 117 and 118 or their inlet openings 109, 110 can be arranged in the same horizontal plane perpendicular to the longitudinal axis 116 or on different horizontal planes. Furthermore, the inlet openings 109, 110 can be inclined downwards by a few degrees toward the bottom region BB.

[0047] How it turns out Figure 1As can be seen, the reaction chamber 101 has a radius that varies along the longitudinal axis 116. In the head region KB, the radius is larger than in the base region BB and in an intermediate region ZB arranged between the head region KB and the base region BB. Towards the top, i.e., towards the inlet 106, the head region KB is flattened. The inlets 117 and 118 or their inlet openings 109, 110 can be arranged in a region or plane of the maximum radius. In the base region BB, the radius can asymptotically approximate a straight line parallel to the longitudinal axis 116.

[0048] In the intermediate region ZB, the lateral surface 102 comprises at least in some regions a curve which satisfies the clothoid equation (ie its curvature K increases with the arc length L from a fixed starting point of the curve to the respective curve point considered according to K = 1 / R = L / A 2< with the radius of curvature R and the clothoid parameter A), so that the radius here changes decreasingly in the direction of the outlet 107 according to a clothoid.

[0049] By combining the arrangement of the inlets 117 and 118, or their inlet openings 109, 110 in the head region KB, and the geometric design of the reaction chamber 101, a three-dimensional vortex flow can be created in a large part of the volume of the reaction chamber 101, in which microorganisms, such as Legionella, can be reliably destroyed. The vortex flow can freely exit the reaction chamber 101 through the outlet 107.

[0050] Further embodiments are shown in the Figures 3 and 4 The constructions of the Figures 3 and 4 The device 200 shown for disinfecting a liquid are, in comparison to the device shown in the Figures 1 and 2 shown configuration are more complex, but they can enable an even more efficient formation of a three-dimensional vortex flow with even stronger forces acting on microorganisms.

[0051] Also the Figure 3 The embodiment shown has an inlet 210 in a head region KB of a reaction chamber 201, which inlet branches into two inlets 202 and 203. Of course, the geometric shape of the head region KB can be different from that shown in the Figures 1 and 3The outer surface of the reaction chamber 201 is designated 207. The radii of the intermediate region ZB and the adjoining bottom region BB are smaller than all radii of the head region KB.

[0052] The incoming liquid is in Figure 3 indicated by arrows. Dots mark areas within the reaction chamber where (intensified) cavitation can occur, which can destroy microorganisms. Also shown are vortex lines that can form in the fluid within the reaction chamber.

[0053] According to different variants, two additional inlets 204, 205 or four additional inlets 204, 205, 208, 209 (see Figure 4 ; in Figure 3only the inlets 204 and 205 are shown) are guided through the jacket surface 207 of the reaction chamber 201. These inlets 204, 205, 208, 209 can be designed as openings / bores with a profile that causes the liquid to enter at a point that is not tangential to the jacket 207. In a further example, the inlets 204, 205 and 204, 205, 208, 209 can be arranged and designed such that they extend over a certain distance into the reaction chamber 201 (i.e., do not terminate at the inner jacket surface), so that here too there is no tangential inflow of the liquid to be treated, but rather an inflow closer to the center. All inlets can be arranged at least partially on one and the same horizontal plane or at least partially on different horizontal planes. The inlets 204, 205 and 204, 205, 208, 209 can be supplied with the liquid to be treated in the device 200 via hoses.

[0054] Both in the variant with four inlets 204, 205, 208, 209, which are guided through the outer surface 207 of the reaction chamber 201, and in the variant with two inlets 204, 205, which are guided through the outer surface 207 of the reaction chamber 201, according to an alternative, the inlet 210, which is guided through the upper end face of the reaction chamber 201, and the inner inlets 202 and 203 can in principle be omitted (which is why these in Figure 4 indicated by dashed lines). This provides a simplified configuration, but in which a three-dimensional vortex flow for destroying microorganisms can generally be achieved less efficiently.

[0055] The embodiments of the device according to the invention illustrated in the figures can be cylindrical and can, for example, have a longitudinal extent of 20 to 100 cm and a diameter of 20 cm to 50 cm. The reaction chamber is formed as a hollow space therein. The shell of the reaction chamber can be a few centimeters in size and, for example, can be made of stainless steel or comprise stainless steel. For example, in all embodiments, the extent of the head region of the reaction chamber along the longitudinal axis of the reaction chamber can be in the upper 30 or 40% of the longitudinal axis, and the extent of the bottom region of the reaction chamber along the longitudinal axis of the reaction chamber can be in the lower (directed towards the drain) 30% or 40% of the longitudinal axis. The intermediate region extends accordingly in between.

[0056] The embodiments of the device according to the invention illustrated in the figures can be installed, in particular, in a building's hot water circulation line and, for example, attached to a wall. Water can then be supplied to the device for disinfection via pumps.
