Title: Continuously working and fluid breathing fluid mixing device and

Process for operating such

The present invention relates in particular to a continuously operating and fluid-breathing fluid mixing device, comprising at least one main mixing chamber with a main mixing chamber, into which a quaternary fluid can be supplied via a quaternary fluid inlet and a tertiary fluid can be supplied via a tertiary fluid inlet such that they mix with one another in the main mixing chamber and leave the main mixing chamber as quintary fluid .

Such fluid mixing devices are known from the prior art. They have different areas of application, and differ among other things in the type of fluids and in which way these fluids are supplied to the fluid mixing device.

For example, it is possible to design such a fluid mixing device in such a way that the fluids are mixed and leave the main mixing chamber as an effectively mixed quaternary fluid, for example a liquid-gas mixture. Such a fluid mixing device can be implemented, for example, as a fumigator in sewage treatment plants. Similar fluid mixing devices are also used in snow cannons and in particular in so-called nucleators. With such nucleators, a mixture of water and (compressed) air is generated, which forms snow cores (nucleides) when it is released into the atmosphere.

From an energetic point of view, known fluid mixing devices have weaknesses in the effectiveness or quality of the mixing of the fluids. In addition, a high pressure is necessary for the artificial acceleration, at least of the quaternary fluid, which must be generated, for example, by means of powerful pumps or compressors. This is ineffective, expensive, and durable - disadvantageous.

The object of the present invention is therefore to offer a fluid mixing device and in particular a continuously operating and fluid-breathing fluid mixing device which allows a more efficient, in particular also more energy-efficient and / or better mixing of fluids.

This object is achieved by a fluid mixing device and by a method for operating such a device according to the independent claims.

This object is achieved in particular by a fluid mixing device and in particular a continuously operating and fluid-breathing fluid mixing device, comprising at least one main mixing chamber with at least one main mixing chamber, the main mixing chamber having a cross section along a main extension direction RX ₂ from an inlet end with a large diameter to one outlet end with a small diameter tapered, wherein at the outlet end a is ₂ direction in its cross section in the main Erstreckungs RX2 expanding nozzle is provided in the main extension direction Rx, and wherein a main mixing chamber, in particular the end face closing off closure part is provided at the inlet end, said closure member comprising: at least one in particular Quaternary fluid inlet opening axially into the main mixing space to supply at least one quaternary fluid to the main mixing space and at least one terti opening tangentially into the main mixing space rfluid inlet to tangentially supply at least one tertiary fluid to the main mixing space, the fluid mixing device being designed such that the tertiary fluid is mixed with the quaternary fluid in the main mixing space, a tertiary fluid-quaternary fluid mixture being formed and being discharged as quintary fluid at the outlet end of the main mixing space Optionally, the tertiary fluid inlet has at least one premixing chamber, in particular a so-called tertiary fluid inlet nozzle, with a premixing space tapering in cross section along a main direction of extension from an inlet end with a large diameter to an outlet end with a small diameter, and the premixing chamber has the following : at least one secondary fluid inlet, which in particular opens axially into the premixing space, around which Supply at least one secondary fluid to the premixing chamber and at least one primary fluid inlet tan potentially opening into the premixing chamber in order to supply at least one primary fluid to the premixing chamber.

This object is also achieved by a method for operating a fluid mixing device as described here, comprising the following steps: supplying a tertiary fluid via the tangential tertiary fluid inlet of the fluid mixing device to the main mixing chamber of the main mixing chamber, so that a vortex flow is formed in the main mixing chamber, whereby a quaternary fluid is conveyed into the main mixing space by a venturi vortex tube effect and / or a particularly external pressurization via the quaternary fluid inlet, a tertiary fluid-quaternary fluid mixture being formed and being output as quaternary fluid at the outlet end of the main mixing space, and optionally also the following is carried out: supplying a primary fluid via a tangential primary fluid inlet into a premixing chamber of a premixing chamber, so that a vortex flow forms in the premixing chamber, where it is acted upon by a venturi vortex tube effect and / or an external pressure in particular A secondary fluid is conveyed into the premixing space via a secondary fluid inlet and the tertiary fluid is formed by a primary fluid / secondary fluid mixture.

The core of the invention is, among other things, the use of mixing spaces or reactor spaces which reduce their cross section along the respective main direction of extension or the main flow direction and which are arranged such that fluids are optionally brought together via the premixing space and the respective inlet in the main mixing space and by the fluid mixing device be performed. The terms “tangential introduction” and “axial introduction” are here optionally understood to mean any type of introduction that is “essentially tangential” or “essentially axial”. In particular, the introduction can deviate by an angle of up to ± 15 degrees, optionally up to ± 10 degrees to complete axiality or tangentiality. The tangential deviation angle is optionally up to ± 15 degrees, optionally up to ± 10 degrees, this positive angle definition defining a deviation of the inlet direction in the direction of the center, that is to say directed away from the wall. A fluid is optionally understood to mean any type of liquid and / or gas, at least one fluid being able to be passed through the fluid mixing device even in different, in particular changing, aggregate states. For example, it is conceivable to pass at least one fluid in a liquid form through the fluid mixing device and then at least partially convert it into a gaseous aggregate state, or vice versa.

In the scope of the invention, a “nozzle” is understood to mean any type of outlet means in order to discharge the fluid guided in the respective space that the nozzle closes at the outlet end.

It should be noted that the scope of the invention speaks of “main directions of extension” and “main directions of flow”. This means that a fluid guided along the main extension direction or main flow direction is guided in this direction when viewed globally. A different local direction can also be taken during this global tour. For example, a fluid in the main direction of extension can also be guided in a spiral meandering manner or in a similar direction, in particular in sections that deviate from the main direction of extension.

It has been found that with a fluid mixing device described here, a more effective mixing or a very energy-efficient mixing of the fluids guided through the fluid mixing device can be achieved. Through the use of the tapered mixing space described and the optional introduction of the primary and secondary fluids in the axial and tangential direction according to the invention, energy-efficient guidance and mixing of the guided fluids takes place optionally in the premixing space, which is caused by the inventive introduction of the resulting tertiary fluids into the Main mixing chamber of the main mixing chamber in the tangential direction and the subsequent mixing with the axially introduced quaternary fluid is further improved in terms of energy. The result is an optimally energy-efficient mixed and, depending on the embodiment, accelerated quintary fluid which leaves the fluid mixing device as quintary fluid via the nozzle. It has also emerged provides that such a fluid mixing device can optionally be formed without active acceleration of the quaternary fluid and / or secondary fluid. According to the invention, the quaternary fluid is thus optionally supplied axially via the closure part in the direction of flow of the quaternary fluid. The feed is optionally from outside the fluid mixing device via the closure part in the main mixing chamber. The feed is optionally from a direction opposite the nozzle direction, in particular from a point behind the closure flap. The closure part optionally closes the front of the main mixing chamber, the only access being the quaternary fluid inlet, in particular axially.

Optionally, as mentioned at the beginning, the tertiary fluid inlet has at least one premixing chamber, in particular a so-called tertiary fluid inlet nozzle, with a premixing space tapering in cross section along a main direction of extension from an inlet end with a large diameter to an outlet end with a small diameter , and wherein the premixing chamber has the following: at least one, in particular axially opening into the premixing chamber, the secondary fluid inlet in order to supply the premixing chamber with at least one secondary fluid, and at least one primary fluid inlet opening tangentially into the premixing chamber in order to supply at least one primary fluid to the premixing chamber.

Instead of this design, the tertiary fluid inlet can be designed as a pipe element, a nozzle or any other corresponding type of fluid guide for the tertiary fluid. It is conceivable to design at least one hole or a comparable opening in the closure part as the tertiary fluid inlet, so that the tertiary fluid can be introduced tangentially into the main mixing space. At this hole or comparable opening, a pipe, a fluid guide, etc. can be ruled out. A premix of primary and secondary fluids to a tertiary fluid is optionally omitted in this variant.

At least three tertiary fluid inlets are preferably provided over the circumference of the closure part. The distribution is preferably distributed evenly over the circumference. Optionally, the quaternary fluid inlet and the tertiary fluid inlet and / or the secondary fluid inlet and the primary fluid inlet are arranged in such a complementary manner to one another that a venturi vortex tube effect forms in the main mixing chamber and / or in the premixing chamber. For example, the quaternary fluid inlet and the tertiary fluid inlet can be arranged such that the quaternary fluid is sucked into the main mixing chamber or its main mixing chamber by the tangential introduction of the tertiary fluid. The same applies optionally to the primary fluid inlet, which opens tangentially into the premixing chamber in such a way that the secondary fluid is sucked into the premixing chamber or its premixing chamber by a vortical vortex tube effect. Mixed forms are also conceivable, wherein, for example, a subset of at least one fluid is sucked in via such a Venturi vortex tube effect, another subset is actively introduced and in particular pumped.

Optionally, the quaternary fluid inlet and / or the secondary fluid inlet are in fluid communication with the atmosphere. The quaternary fluid and / or the secondary fluid, air and in particular compressed air, are also optional. It is possible that the quaternary fluid inlet and / or the secondary fluid inlet are in direct fluid communication with the atmosphere. This is particularly advantageous if, as described above, the quaternary fluid inlet and the tertiary fluid inlet and / or the secondary fluid inlet and the primary fluid inlet are arranged such that they complement one another in such a way that a venturi vortex tube effect forms in the main mixing chamber or in the premixing chamber. When the quaternary fluid inlet and / or the secondary fluid inlet is connected directly to the atmosphere, air is drawn from the atmosphere into the fluid mixing device in a simple and reliable manner. The quaternary fluid and / or the secondary fluid can optionally be a compressed gas and in particular compressed air in order to increase / support the inflow. It is conceivable to bring a pressure source, for example a compressor, a pump or a similar pressure-acting arrangement, into fluid communication with the quaternary fluid and / or secondary fluid inlet in order to pressurize the fluid carried there and to feed it to the mixing chamber.

Optionally, the quaternary fluid inlet and / or the secondary fluid inlet are pressurized and / or the quaternary fluid and / or the secondary fluid be artificially accelerated. The same applies optionally accordingly for the primary fluid inlet and / or the tertiary fluid inlet or the primary fluid and / or the tertiary fluid.

The quaternary fluid and / or the secondary fluid are optionally supplied by pressurization, optionally under 0.1-10 bar, further optionally under 0.5-3 bar absolute. The supply of the tertiary fluid and / or the primary fluid is optionally carried out by pressurization, optionally under 1 - 80 bar, further optionally under 3 - 50 bar absolute. The quaternary fluid and / or the secondary fluid are optionally a gas and in particular air.

The main mixing space and / or the premixing space are optionally designed as a body of rotation about their respective main extension axis.

The main mixing space and / or the premixing space are optionally in their respective main extension directions Rx2; Rx _{302 leads} at least in sections in the form of a continuously tapering and in particular tapering hyperbolic funnel. In a simplified design, radii, polynomial pieces or comparable geometries can also be used here. The hyperbolic funnel is optionally designed as a hyperboloid funnel, namely as a so-called Torricelli trumpet and in particular as a rotating body of a graph with the form y = l / x, with the definition range X> 1, rotating about the X axis. Solid bodies with a deviation of ± 10% from this geometric shape also apply within the scope of the invention. It has been found that a fluid guided in such a solid is guided in a particularly effective manner and is optionally guided in an accelerable manner.

Optionally, the Quartärfluideinlass and / or tertiary fluid inlet and / or Se are kundärfluideinlass and / or the primary fluid inlet in their respective cross-section along their heads _S treckungsrichtung Rx4oo; Rx3oo; Rx2oo; Rxioo tapering from an inlet end with a large diameter to an outlet end with a small diameter and in particular in the form of a tapering hyperbolic funnel. Also for such a hyperbolic funnel the above apply. This means that such a hyperbolic funnel is optionally designed as a radius, polynomial or hyperboloid funnel, namely as a so-called Torricelli trumpet and in particular as a rotational body of a graph with the form y = l / x, with the definition range X> 1, rotating around the X- Axis. Solid bodies with a deviation of ± 10% from this geometric shape also apply within the scope of the invention.

Optionally, a nozzle is provided on the main mixing chamber and / or on the premixing chamber and in particular in the outlet area or an outlet end of the mixing chamber. This nozzle can be designed as a Laval nozzle. It can be designed as an expanding nozzle. Such a nozzle can have the shape of a hyperbolar and in particular hyperboloid funnel. It can be formed as a diffuser. Optionally, the nozzle is designed in such a way that it rectifies the vortex flow of the fluid which is conducted in the main mixing chamber or the premixing chamber and / or generates the highest possible outflow speed. Analogously to the geometry of the main mixing chamber or the premixing chamber, the nozzle can in particular be designed in opposite directions.

It is possible to provide such a nozzle with a spiral flow guide in order to force the guided fluid into a spiral flow path, in particular with a gradient that decreases in the direction of flow. Such a Spiralströmungsfüh tion can be internals and in particular projections that force the fluid guided in the nozzle into a spiral flow. It is also possible to form the nozzle in a twisted shape, so that such a spiral flow guide and / or a spiral flow path result. Optionally, the spiral shape is chosen so that there is a hyperbolic and in particular hyperboic decreasing slope.

Optionally, at least one fluid inlet, in particular the primary fluid inlet and / or the tertiary fluid inlet, has at least one fluid line means and in particular primary fluid line means or tertiary fluid line means. Optionally, the fluid inlet is at least one fluid line with at least one fluid reservoir, for example a water reservoir, or a fluid pump, for example a water pump, in fluid communication. Optionally, the fluid reservoir is a pressure reservoir in which the fluid to be guided is under pressure and is thus optionally supplied to the inlet under pressure.

Optionally, at least a portion of the primary fluid line means and / or the tertiary fluid line means and / or at least one of the fluid inlets and / or at least one of the chambers has at least one fluid temperature control means. Such a fluid temperature control means can be, for example, a heat exchanger assigned to the main mixing chamber and / or the premixing chamber. This can in particular have at least one fluid line running in and / or on the wall of the chamber. The advantage of such a fluid temperature control means is the possibility of heating and / or cooling a fluid guided in the respective fluid conduit and / or the respective chamber and / or the respective fluid inlet. For example, a primary fluid introduced into the premixing chamber can be preheated or cooled via a heat exchanger assigned to the main mixing chamber, so that it is introduced into the premixing chamber in a heated / cooled state and mixed there with the secondary fluid. The (pre) heating or cooling can optionally take place in such a way that the state of aggregation of the guided fluid changes, i.e. the fluid temperature control means can be designed such that the fluid that comes into contact with it changes its physical state. For example, a previously liquid fluid can be converted into an essentially partially gaseous fluid by contact with the fluid temperature control agent, or vice versa. The fluid temperature control means is optionally designed as a fluid preheating means. It is possible to design the fluid temperature control agent as a fluid coolant. This is also covered by the invention and everything that has been said regarding the training for heating applies accordingly to the training for cooling. In this way, for example, cooling of the at least one guided fluid can be achieved. A fluid temperature control means can optionally be connected to an external cooling line means, for example a line system connected to a water reservoir, via which water or a similar coolant can be supplied.

The fluid temperature control means optionally has at least one fluid conduction means, which is arranged in a spiral or the like in a meandering manner in and / or on the wall of the main mixing chamber and / or premixing chamber and / or at least in sections in and / or at least in sections on the wall of the main mixing chamber and / or premixing chamber from the nozzle to the inlet, in particular the tertiary fluid inlet or primary fluid inlet is formed. An effective heat transfer can be achieved by guiding the fluid conduction means in the respective wall. In addition, it is possible to design the fluid conduction means or the fluid temperature control means in such a way that it cools or heats the nozzle and / or the chamber wall. Optionally, the fluid is supplied as a cooled fluid to the fluid mixing device and in particular to the fluid temperature control means in order to be heated via the fluid temperature control means. It is also conceivable to design the fluid temperature control means in such a way that at least one guided fluid is cooled.

Optionally, the fluid conduit is arranged in a spiral and / or meandering manner. Furthermore, it is optionally designed in such a way that it serves to temper the fluid and / or to change the pressure of the guided fluid and / or to bring the nozzles and / or chamber wall to temperature. Optionally, it is conceivable that the fluid conduit has a round, and in particular circular cross section. A round cross-section is optionally viewed as a cross-section with a constant development of the wall. It is also optionally possible to provide guide devices in the fluid line means, in particular in order to bring about a turning of the flow of the guided fluid. These guide devices are preferably designed such that they force the guided fluid into a spiral flow along the main direction of flow in the fluid conduit.

Optionally, the tertiary fluid inlet and / or the primary fluid inlet each have at least one valve means in order to stop and / or enable the supply of the fluid carried therein and / or to regulate the supply quantity. Optionally, the valve means is designed in such a way that it allows the inflow of the tertiary fluid and / or the primary fluid when a sufficient tertiary fluid or primary fluid pressure and / or a sufficient tertiary fluid temperature or primary fluid temperature has been reached in order to be in the respective main mixing chamber or Premixed chamber to form a venturi vortex tube effect and in particular to suck in quaternary fluid or secondary fluid and / or to allow it to flow in under pressure.

The valve means is optionally designed such that it only opens when the primary fluid supplied via the primary fluid inlet and the primary fluid pressure source, for example a fluid reservoir or a fluid pump, has the sufficient temperature or the sufficient pressure for the Venturi vortex tube effect (low pressure in the center ) reached in the premixing chamber. The same applies optionally to a valve means optionally assigned to the tertiary fluid.

Optionally, at least one flow guide for the fluid flow is provided in the quaternary fluid inlet and / or tertiary fluid inlet and / or secondary fluid inlet and / or primary fluid inlet and / or main mixing space and / or pre-mixing space. It is conceivable that the quaternary fluid inlet and / or the tertiary fluid inlet and / or the secondary fluid inlet and / or the primary fluid inlet and / or the main mixing chamber and / or the main mixing chamber and / or the premixing chamber are at least partially rotated in one another, in particular by for the therein, in order to form the electrical conduction guided fluid to define a twisted flow path. It is also conceivable that they are designed in such a way that they force the fluid guided therein into a flow path that is twisted in itself. It is conceivable to design at least one current guide, in particular a spiral flow guide, for example in the form of a hyperbolic-like, in particular hyperbolic spiral, in order to force the fluid carried into a spiral flow and, in particular, a logarithmically decreasing hyperbolic spiral path. Optionally, at least one current guide, in particular a spiral flow guide, is provided, for example as an installation means with at least one guide plate or a similar guide element. It is also possible to carry out such a current conduction guide integrally with the wall and in particular by means of appropriately designed elevations in the wall, which correspondingly reduce the cross section in cross section in the flow path, so that the fluid guided therein is forced into a change in direction. In the case of a spiral arrangement of the current conduction, this results in a spiral flow path of the guided fluid. Optionally, it is conceivable for the respective inlet or the chamber and in particular the walls of the respective inlet or chamber to be twisted around the respective main axis of extension, thereby forming a spiral Flow guidance in the flow path results. It is conceivable to design the current conduction in such a way that there are decreasing and / or increasing slopes in the flow path and in particular in a spiral helical path. The current conduction is optionally designed in such a way that the slope along the main direction of extension is reduced spirally. The current conduction is optionally designed for flow rectification in order to rectify or laminarize a flow carried there.

Optionally, the cross section of the quaternary fluid inlet and / or the tertiary fluid inlet and / or the secondary fluid inlet and / or the primary fluid inlet and / or the main mixing space and / or the premixing space are round and in particular circular. There are also elliptical and the like continuously developed cross-sectional shapes applicable.

Optionally, the tertiary fluid inlet and / or the primary fluid inlet are pivotable about a swivel axis orthogonal to the respective main flow direction in the opening chamber in a swivel direction opposite to the main flow direction RX2; RX _{302 designed} to be pivotable in a range from 90 degrees to 150 degrees. In this way, for example, a fluid guided via the respective inlet can be accelerated tangentially and, moreover, already in the main flow direction. In particular when the fluid mixing device is started, the respective inlet is optionally pivoted at an angle of 90 degrees, that is to say tangentially orthogonally to the main axis of extension. During operation, this swivel angle can then be increased up to 150 degrees, so that the direction of introduction increasingly points in the main flow direction.

Optionally, the premixing chamber has a closure part closing the premixing space at an inlet end, on which optionally at least one secondary fluid inlet and at least one primary fluid inlet are provided. In addition, the premixing chamber optionally has, at an outlet end of the mixing space, a nozzle which widens in cross section in the main direction of extension, as has already been described above. It is conceivable that the closure parts described here on the premixing space or

To form the main mixing room integral with the respective wall of the room. It is also conceivable to provide them as an independent component. In this context, in particular, the respective inlets for the fluids can then be provided on the closure part at very low cost.

It is conceivable to provide a plurality of primary fluid inlets and / or tertiary fluid inlets on the premixing chamber or the main mixing chamber. In particular, the respective inlets are optionally in particular evenly distributed over the circumference of the respective chamber or the respective closure part.

The main mixing chamber and the premixing chamber optionally form a recursive or fractal vortex tube arrangement. This means in particular that the main mixing chamber and the premixing chamber are identical in their basic geometry, but are of different sizes. For example, the main mixing chamber or the main mixing chamber can have a hyperbolic cross section, while the premixing chamber has an identical hyperbolic cross section, but with a reduced size.

Optionally, the quaternary fluid inlet and / or the secondary fluid inlet each have at least one fluid guiding element which at least partially protrudes into the respective main mixing space or premixing space, which is optionally designed, inter alia, as a hyperbolic funnel. All forms can be used here, which are also mentioned here in relation to the shape of the main mixing space or the premixing space. This fluid guide element is optionally a tube or a similar fluid channel. Optionally, the fluid guide element continuously connects to the quaternary fluid inlet or the secondary fluid inlet. Optionally, the transition of the wall of the quaternary fluid inlet or the secondary fluid inlet to the respective fluid guiding element is continuous. Optionally, the wall geometry of the quaternary fluid inlet or the secondary fluid inlet in the fluid guiding element continues continuously. If, for example, the inner geometry of the quaternary fluid inlet and / or the secondary fluid inlet is designed as a funnel and in particular as a hyperbole-like, in particular hyperbolic funnel, this geometry can optionally also be continued in the fluid guide element. It is also conceivable that the fluid line telement with parallel inner wall parts, for example as a pipe section. Other interior geometries are also conceivable. The above from this paragraph can optionally be identical or correspondingly also apply to the primary fluid inlet and / or the tertiary fluid inlet.

The fluid guide element is optionally guided along and in particular coaxially to the respective main directions of extent R _X 2 and / or R _X302 . Optionally, the fluid guide element extends at least 1/2 times the length of the main mixing space or the premixing space, optionally 2/3 the length of the main mixing space or the premixing space in the direction of the outlet end of the respective main mixing space or the premixing space, and further optionally to the area of the outlet end of the respective main mixing room or the premixing room. The above from this paragraph can optionally apply identically or correspondingly also for the primary fluid inlet and / or the tertiary fluid inlet

Optionally, the closure part and / or the inner wall of the main mixing space or premixing space are rounded off to one another. Optionally, the closure part and / or the fluid guiding element are rounded to one another. Optionally, the outer geometry of the fluid guide element in the main mixing space or in front of the mixing space in the form of a clothoid, a parabola, a radius or the like is continuously curved into the inner wall of the closure part. Optionally, the fluid guiding element is designed as an elevation on the inner wall of the respective closure part of the main mixing space or the premixing space. Optionally, the closure part is at least on its inner wall facing the main mixing space or the premixing space continuously or multiply curved, and in particular has a wavy cross section, in particular with an elevated edge region in the wall area of the main mixing space or the premixing space, followed by a wave trough and optionally a subsequent wave crest in the area of the main extension axis of the main mixing space or the premixing space or the introduction area of the quaternary fluid inlet or the tertiary fluid inlet. The above from this paragraph can optionally be identical or correspondingly also apply to the primary fluid inlet and / or the tertiary fluid inlet Optionally, the quaternary fluid inlet and / or secondary fluid inlet is guided from the closure parts from the direction of the main extension directions R _X 2 and / or R _X302 by means of such a fluid guide element and in particular a pipe section into the main mixing space and / or premixing space. Optionally, this fluid line extends and in particular the pipe section to the outlet ends of the main mixing chambers and / or premixing chambers. The above from this paragraph can optionally apply identically or correspondingly also for the primary fluid inlet and / or the tertiary fluid inlet

It should be noted that this fluid guiding element can be used in any fluid mixing device which has at least one main mixing chamber with at least one main mixing space which, in its cross section along a main extension direction (R _X 2), extends from an inlet end with a large diameter to an outlet end tapered to a small diameter, and wherein at the inlet end there is provided a closure part which closes the main mixing space, in particular on the end face, the closure part having the following:

At least one quaternary fluid inlet, which in particular axially opens into the main mixing space, in order to supply at least one quaternary fluid to the main mixing space, and at least one tertiary fluid inlet opening tangentially into the main mixing space, in order to feed at least one tertiary fluid tangentially to the main mixing space, the fluid mixing device being designed such that a Ver mixing of the tertiary fluid with the quaternary fluid takes place, a tertiary fluid-quaternary fluid mixture being formed and being discharged as quaternary fluid at the outlet end of the main mixing space.

As mentioned, the invention also relates to a corresponding method for operating such a fluid mixing device. All of the characteristics and embodiments mentioned with regard to the fluid mixing device also apply to the method, although for redundancy reasons it is not explicitly dealt with, but only reference is made to what is mentioned here. Conversely, all that applies to the process also applies to the fluid mixing device.

So it is optionally conceivable that in addition to conveying via a Venturi vortex tube Effect especially the quaternary fluid and / or the secondary fluid active in the

Main mixing space or the premixing space are conveyed, for example by means of a fluid pressure reservoir and / or a fluid pump.

It is also conceivable that the tertiary fluid-quaternary fluid mixture leaves the main mixing chamber as a quintary fluid and is fed to a downstream turbine. In this way, electrical and / or kinetic energy can be obtained, for example, via the fluid mixing device.

The field of application of the fluid mixing device described here extends from mixing devices for mixing different fluids, through the use as fumigants, to use in snow cannons and similar snow-making devices. All of these application forms are encompassed by the invention.

1 and 2 show a possible embodiment of the fluid mixing device according to the invention in an isometric view (FIG. 1) and a sectional view (FIG. 2).

In this embodiment, the fluid mixing device 1 according to the invention comprises at least one main mixing chamber 2 which has a main mixing chamber 4, which tapers in cross-section along a main extension direction Rx2 from an inlet end 6 with a large diameter D6 to an outlet end 8 with a small diameter Ds.

At the outlet end 8 there is optionally provided in this embodiment a nozzle 10 which widens in the main direction of extension RX2 in its cross section in the main direction of extension Rx2.

At the inlet end, the main mixing chamber 2 is provided, in particular closing the end of the closure part 12, which has the following: at least one quaternary fluid inlet opening axially into the main mixing chamber 4, around which

Main mixing space 4 to supply at least one quaternary fluid, and at least one tertiary fluid inlet 300 opening tangentially into the main mixing space 4 in order to tangentially feed the main mixing space 4 to at least one tertiary fluid. The tertiary fluid inlet 300 optionally has at least one premixing chamber 302, with a premixing chamber 304 tapering in its cross section along a main extension direction Rx3oo from an inlet end 306 with a large diameter to an outlet end 308 with a small diameter. The premixing chamber 302 in turn optionally has the following: optionally at least one secondary fluid inlet 200, in particular axially opening into the premixing chamber 304, in order to supply at least one secondary fluid to the premixing chamber 304, and at least one primary fluid inlet 100 tangentially opening into the premixing chamber 304, around the premixing chamber 304 supply at least one primary fluid.

The core of the invention is, inter alia, the formation of the main mixing chamber 4 and the premixing chamber 304 in its cross-section tapering in the respective main direction of extension RX2 or RX ₃₀₂ and the introduction of the fluids supplying the respective chamber 4 or 304 in the axial or tangential direction. It has been found that in this way an optimal mixing and / or a very energy-efficient mixing of the guided fluids can be achieved. In addition, this arrangement favors the generation of a spray with a very fine droplet distribution. The starting behavior of such a Fluidmischeinrich device has improved compared to devices known from the prior art.

In the embodiment shown here, the quaternary fluid inlet 400 and the tertiary fluid inlet 300 and / or the secondary fluid inlet 200 and the primary fluid inlet 100 can optionally be arranged complementarily to one another such that a venturi vortex tube effect occurs in the main mixing chamber 2 or the premixing chamber 302 trains. In this way, for example, in the area of the tertiary fluid inlet 300 or the premixing chamber 302, the secondary fluid is drawn in via the secondary fluid inlet 200 without the mechanical fluid being particularly accelerated or pressurized. The same is possible in the area of the quaternary fluid inlet 400, a venturi flow sucking the quaternary fluid 400 through the quaternary fluid inlet 400 into the main mixing chamber 2 or the main mixing chamber 4 due to the resulting venturi vortex tube effect. However, active delivery could optionally be arranged at least in part at the quaternary fluid inlet 400 as well as at the secondary fluid inlet 200. A fluid mixing device designed in this way has, in particular, an optimized starting behavior, which means in particular that there is optionally no need for active delivery of the quaternary fluid into the main mixing chamber 4. Optionally, no special mechanical components such as compressor groups, compressors, pumps or similar devices are required to start the device 1. In the version with active acceleration of secondary and / or quaternary fluid, the acceleration is favored by the low pressure in the center of the primary and main mixing chambers.

As shown in FIGS. 1 to 4, it is conceivable that the main mixing space 4 and / or the premixing space 304 in their respective main extension direction Rx2; RX _{302 are performed} at least in sections in the form of a continuously tapering and in particular special tapering hyperbolic, in particular hyperboloid funnel. In this way, the fluid contained therein is optimally flow-guided or can be accelerated in an energy-efficient manner.

In particular, it is conceivable that the quaternary fluid inlet 400 and / or the tertiary fluid inlet 300 and / or the secondary fluid inlet 200 and / or the primary fluid inlet 100 and / or the main mixing space and / or the premixing space in their respective cross section along their main extension direction Rx4oo ; Rx3oo; Rx2oo; Rxioo tapering from an inlet end with a large diameter to an outlet end with a small diameter and in particular in the form of a tapering hyperbolic, in particular hyperboloid funnel.

Furthermore, it is conceivable that at least one of the inlets 400; 300; 200; 100 or rooms 4, 304 is designed to be rotated in itself and / or to define a flow path that is rotated in itself for the fluid guided therein. It is conceivable to provide at least one current conduction, in particular a current conduction for the fluid flow, for example in the form of a hyperbolic installation and in particular a hyperbolic spiral, in order to urge the guided fluid into a spiral flow and in particular into a logarithmically decreasing hyperbolic spiral path. Such an embodiment is shown, for example, in FIG. 6. In addition, a spiral current conduction in the form of an insert in the inlets 400; 300; 200; 100 possible. The current-conducting guides 16 are designed here in the form of projections of the wall 14, which extend at least in sections spirally along the wall 14 of the main mixing chamber 4. Such flow guides 16 can also be seen in the premixing chamber 302 and / or in fluid line means 110. In addition, it is conceivable to also provide such current conduction guides 16 in the nozzles 10 and 310. It is also possible to design at least one chamber and / or at least one inlet, for example the main mixing chamber 2 or the premixing chamber 302, to be twisted and, in particular, to twist around the axis Ax, i.e. the main extension axis, so that a spiral flow path is in Form of a current conduction results. This flow path is preferably designed to decrease logarithmically in its slope. The current conduction is optionally designed in such a way that it forces the guided fluid into a spiral flow and in particular into a logarithmically decreasing, hyperbolic spiral path.

The main direction of extension Rx4oo; Rx3oo; Rx2oo; Rxioo optionally form the main flow directions of the fluids carried there.

As mentioned, there is a nozzle 10 at the outlet end 8 of the main mixing chamber 2. A similar nozzle 310 can optionally be located at the outlet end 308 of the premixing chamber 302. This nozzle can have the form of a hyperbolic and in particular hyperboloidal diffuser. In addition, it is conceivable to nozzle 10, 310 or the area at the outlet end 8; 308 of the respective chamber as a Laval nozzle. The nozzle 8 is optional; 308 designed such that it rectifies the vortex flow of the fluid, which is guided in the main mixing chamber 2 or the premixing chamber 302, and / or generates the highest possible outflow rate. Analogously to the geometry of the main mixing chamber 2 or the pre-mixing chamber 302, however, the nozzle can in particular be designed in opposite directions. If necessary, it can also be twisted and / or contain corresponding guide elements for guiding the flow. The current conduction is optionally designed to rectify the flow in order to rectify a flow carried there. In particular, it is conceivable to design the nozzle in such a way that the vortex flow emerging from the main mixing chamber is laminarized and accelerated. As shown in particular in FIGS. 1, 3 and 4, the premixing chamber 302 optionally has a closure part 312 which closes the premixing chamber 304 at an inlet end 306. At least one of the secondary fluid inlet 200 and / or the at least one primary fluid inlet 100 can be provided on this closure part 312. In addition, the nozzle 310, which _widens in cross section in the main _{direction of extension} R _X302 , is optionally provided at the outlet end of the mixing chamber 304.

In this exemplary embodiment, the main mixing chamber 2 and optionally the premixing chamber 302 are optionally formed as a recursive or fractal vortex tube arrangement. The geometry of the main mixing chamber optionally corresponds in particular to that of the premixing chamber and vice versa, with different dimensions being realized. Theoretically, it is conceivable to provide at least one further appropriately designed premixing chamber (not shown) as primary fluid inlet 100, which, however, is designed with smaller dimensions corresponding to premixing chamber 302. This recursive or fractal formation of mutually conductive chambers can in principle be continued in multiple stages, the upstream vortex tube or the upstream chamber being selected in its geometry smaller than the chamber following in the flow direction in the flow direction.

In particular, to enable the Venturi vortex tube effect, the quaternary fluid inlet and / or the secondary fluid inlet are optionally designed to be in fluid communication with the atmosphere. In addition, it is conceivable that the quaternary fluid and / or the secondary fluid are air or gas and are actively accelerated. Here, reference is optionally made to the corresponding previous passages on pressurization.

The embodiments of the fluid mixing device shown here pass through the following optional steps during operation and in particular when mixing and / or accelerating fluids. In an optional first step, a primary fluid 100 is fed via the optional tangential primary fluid inlet 100 into the optional premixing chamber 304 of the premixing chamber 302, so that in the optional premixing chamber chamber 304 forms a vortex flow, a secondary fluid optionally being conveyed into the premixing chamber 304 by a Venturi vortex tube effect and / or by in particular external pressurization via the optional secondary fluid inlet 200. With this promotion, a primary fluid-secondary fluid mixture is formed, which can be referred to as tertiary fluid. The primary fluid can optionally be supplied via a primary fluid pressure reservoir 104 and / or a primary fluid pump.

The tertiary fluid optionally formed in the premixing chamber 302 is fed via the tangentially arranged tertiary fluid inlet 300 to the main mixing chamber 4 of the main mixing chamber 2, so that a vortex flow is again formed in the main mixing chamber 4. Among other things the quaternary fluid is conveyed into the main mixing chamber 4 via the quaternary fluid inlet 400 by means of a venturi vortex tube effect which arises and / or by in particular external pressurization, so that a tertiary fluid / quaternary fluid mixture forms which forms the main mixing chamber 4 at the outlet end 8 as quaternary fluid , especially towards Rxsoo. The quaternary fluid inlet 400 is formed in the closure part.

As shown in Fig. 1, the introduced into the main mixing chamber 4 ter tiärfluid and mixed with this quaternary fluid through the main mixing chamber 4 ent along the main flow direction Rx2 in a spiral path, here by the dashed arrow

is shown. Optionally, this spiral path is changed by means of appropriate flow guidance in the nozzle and, in particular, is increasingly changed logarithmically, so that a changed spiral path R "x5oo results. This results in a particularly effective acceleration of the vortex flow emerging from the main mixing chamber 2.

The fluid supply of the primary fluid and / or tertiary fluid of the Fluidmischeinrich device optionally takes place via a pressure fluid reservoir. Instead of or in addition to a pressure fluid reservoir, a pressureless fluid reservoir for gaseous or liquid fluids can also be used, in which case an additional compressor and, in particular, a fluid pump are optionally provided. This fluid pump optionally creates one higher fluid pressure than that prevailing in the fluid supply line for the respective fluid inlet. The same applies optionally to the pressure in the fluid reservoir.

As shown in particular in FIGS. 1 and 2, it is conceivable that at least one inlet and / or at least one chamber 2; 302 and in particular the primary fluid inlet 100 and / or the tertiary fluid inlet 300 have at least one fluid line means 102 and in particular at least one primary fluid line means 102 or tertiary fluid line means, via which they are in fluid communication with a fluid reservoir 104 or a fluid pump.

In a particular embodiment, at least a portion of the primary fluid line means 102 and / or tertiary fluid line means has at least one fluid temperature control means 106. In the embodiment shown here in FIG. 2, the fluid temperature control means 106 is designed, for example, as a heat exchanger 106 assigned to the main mixing chamber 2. This includes in particular at least one fluid line 110 running in the wall 14 of the main mixing chamber 2. This fluid line 110 is optionally routed at least in sections in the wall 14 of the main mixing chamber 2 from the nozzle 10 to the inlet end 6, with it being in thermal coupling with the main mixing chamber 4 stands. As soon as the main mixing chamber 4 has a higher temperature than the guided primary fluid, the primary fluid heats up, which at the same time leads to cooling of the wall 14 or the nozzle 10. As soon as the main mixing chamber 4 has a lower temperature than the guided primary fluid, the primary fluid cools down, which at the same time leads to heating of the wall 14 or the nozzle 10. It is conceivable to design the fluid temperature means 106 and in particular the heat exchanger 106 described here in such a way that the fluid carried therein changes its state of matter and in particular a liquid state of matter to a gaseous state of matter.

As shown in FIG. 2, it is optionally possible to conduct the fluid line 110 spirally in or on the wall of the main mixing chamber or on the wall of the main mixing chamber, preferably from the nozzle to the area of the main mixing chamber, in particular with the closure means. A guide in or on the closure means is also conceivable. This is optional for fluid temperature control Fluid reservoir 104 is supplied via the fluid line 102 to the nozzle 10 or in the inlet region 8 of the main mixing chamber 2, where the fluid and in particular the primary fluid spirally extends around the main mixing chamber 4 and is guided up to the closure part 12. From there, the fluid is supplied to the primary fluid inlet 100 via a further fluid conduit 102. In addition to the fluid temperature control, temperature control of the nozzle or of the main mixing chamber wall 14 is thus optionally achieved.

Optionally, it is conceivable that the tertiary fluid inlet 300 and / or the primary fluid inlet 100 have at least one valve means 108 in order to stop and / or enable the supply of the fluid conveyed therein and / or to regulate the supply quantity. As already mentioned, in this way, primary fluid can optionally be supplied to the premixing chamber 304 via the valve means 108 only when sufficient primary fluid pressure has built up. In this way it is ensured that a Venturi vortex tube effect and in particular the suction of the secondary fluid take place via the secondary fluid inlet 200 without the secondary fluid having to be actively promoted. The same applies to a valve means in front of the main mixing chamber 2.

Active delivery of the quaternary fluid and / or the secondary fluid via the respective inlet 400 is of course also optional; 200 realizable, for example by using appropriate pressure reservoirs or feed pumps.

5 shows an embodiment in which the tertiary fluid inlet 300 can optionally be pivoted in a range of 90 to 150 degrees in a pivoting direction counter to the main flow direction Rx2 by a pivot axis As3oo running orthogonally to the main flow direction Rx2 in the opening chamber 4, here the main mixing chamber 4 is trained. This pivotability is represented here by the premixing chamber 2 shown in full lines and the premixing chamber 302 pivoted by the angle a and shown in broken lines. In the pivoted state, the tertiary fluid is introduced tangentially but further in the direction of the main flow direction RX2 of the main mixing chamber 2, and in this respect the fluid flow is accelerated in particular in the outlet region of the chamber. The pivot angle a is represented here by the pivot angle cu of 90 degrees and the further pivot angle of <12 with 150 degrees, always starting from the main axis of extension Ax. The Venturi vortex tube effect and the flow velocity in the axial direction, in particular in the direction Rxsoo of the fluid mixing device, can be influenced via the size of the swivel angle. The axial swivel angle a can be varied for variable feed control.

As already mentioned, the inlets 400 are optional; 300; 200; 100 and / or the chambers are provided in the form of hyperbolic funnels, as a result of which improved fluid guidance and in particular in the case of the quaternary and secondary inlets 400; 200 an improved fluid suction compared to a simple aperture opening is achieved. This applies in particular to the case in which the quaternary fluid inlet 400 or the secondary fluid inlet 200 is connected to the atmosphere.

Fig. 7 shows an embodiment of the fluid mixing device, which may correspond in its basic structure to the previously described embodiment. In this respect, reference is made here to all that is described in relation to this previous embodiment. As described in the general part, it is possible to provide specially shaped quaternary fluid inlets 400 and / or secondary fluid inlets 200. At least one of these optionally has at least one fluid guiding element 600 and optionally a fluid guiding element 600, in particular in the form of a hyperbolic funnel, in particular a hyperbolic tapering fluid guiding element and in particular a pipe section 600 which projects into the main mixing chamber 4 or the premixing chamber 304. At the mouth 608 of the fluid guide element 600 there is a stronger Venturi vortex tube effect due to the higher rotational speed of the fluid mixture, in particular the tertiary-quaternary mixture, and consequently a lower pressure than directly at the inlet 400 or 200 at the closure parts 12 or 312. With regard to the embodiment of the fluid guiding element, we refer to everything mentioned in the introductory part as an optional embodiment.

As also shown in FIG. 7, the fluid guide element 600 optionally adjoins the quaternary fluid inlet 400 or the tertiary fluid inlet 200, and in particular the transition of the wall of the quaternary fluid inlet or the tertiary fluid inlet is optional. let steadily trained for the respective fluid guide element. Here, too, everything mentioned above still applies. Further optionally, the closure part 12 and / or closure part 312 and / or the inner wall of the main mixing space 4 or premixing space 304 are rounded off to one another. This is shown here by the fillet 604 shown in dashed lines. Optionally, the closure part 12 and / or 312 and / or the fluid guide element 600 are rounded off to one another. This is shown in FIG. 7 by the fillet 602.

The fluid guide element protrudes here optionally by the length 1 into the main mixing chamber 4 and / or the premixing chamber 304. This length can optionally be up to 1/2 times the

Length L of the main mixing space or premixing space, optionally up to 2/3 of the length L of the main mixing space or premixing space in the direction of the outlet end of the respective main mixing space or premixing space accordingly. Further optionally, the fluid guide element 600 can protrude with its length 1 to the area of the outlet end 8 or 308 of the respective main mixing space or the premixing space. The length L can optionally be considered as length Li without nozzle or as length Li plus length L2 of the nozzle.

5 is exemplarily shown in Fig., That the direction in the main mixing chamber 2 befindli- che tertiary fluid mixture as Quartärfluid Quintärfluid along the main flow RX _east OO a turbine 500 can be supplied.

5 also shows an embodiment in which, as an example, the closure part 12 is designed as an independent component and in the region of a joining edge 18 adjoins the one end wall 14 of the main mixing chamber 2. 1 shows, by way of example, an integrally formed closure part 12.
