Definitions
- the invention relates to a pressure exchanger for transferring pressure energy from a first liquid of a first liquid system to a second liquid of a second liquid system, comprising a housing with connection openings in the form of inlet and outlet openings for each liquid and one inside the housing Its rotor has a plurality of through-going rotor channels with openings arranged around its longitudinal axis on each rotor end side, whereby the rotor channels communicate with the ports of the housing via housing-side flow openings The rotation of the rotor alternately lead liquid at high pressure and liquid at low pressure of the respective systems.
- Such a generic pressure exchanger is known from US Pat. No. 6,540,487 B2.
- This type of pressure exchanger is equipped without an external drive. To commission it, a complex process is required to cause such a pressure exchanger to put the rotor in rotation.
- the fluid flow is primarily responsible for the rotational movement of the rotor, which impinges on the end faces of the rotor and the openings located therein through the housing-side flow openings from an oblique direction.
- an equilibrium state will set in the pressure exchanger, due to which the rotor rotates at an approximately constant speed.
- a disadvantage is its ein ⁇ limited operating range and the resulting during operation in the Rotorka ⁇ resulting mixing of alternately located there two liquids.
- the invention is based on the problem of developing a Druckaustauseher in which arise in a pressure exchange reduced mixing losses.
- the solution to this problem provides that in the rotor channels and starting from or after the openings, a flow-shaping is arranged as a channel contour which deflects the rotor channel flow.
- the risk of mixing in the rotor channels is further reduced if the shaping arranged in the inlet region of the rotor channels is designed as a channel contour which is equal to the channel flow. This causes ner speed of 20 - 30% of the total length of a pipe channel after a diffusbe ⁇ rich within a rotor channel a velocity profile is formed with an approximately homogeneous velocity field.
- the inlet openings and / or their downstream channel starts have a design which makes the flows in the rotor channels more uniform. This also results in a uniform velocity profile in the rotor channels, whereby a mixing of the two different and in the rotor channels a pressure-exchanging fluids is minimized.
- the rotor entry edges formed therebetween are designed with the wall surfaces following in the direction of flow in such a way that the adjusting rotor relative flow is absorbed bumplessly by the rotor channels and deflected in the direction of the rotor channel length.
- the velocity triangle at the entrance of the rotor channels changes affinely, that is, the peripheral component c u changes to the same extent as the inflow velocity c of the liquid.
- This also increases the drive torque which acts on the rotor, which leads to an increase in the rotor speed.
- the friction torque acting on the rotor As the rotor speed increases, so does the friction torque acting on the rotor and having a braking effect.
- the peripheral speed of the rotor Because of the linear relationship between the drive torque Mi rising with increasing peripheral component c u and the friction torque M R increasing in proportion to the rotational speed, the peripheral speed of the rotor always adjusts itself so that there are similar speed triangles at the rotor inlet for all volume flows.
- self-regulation occurs which guarantees the state of the bumpless flow for each set volume flow.
- Lumenströme the main currents a readjustment of the rotor speed due to the congruent speed triangles and a bumpless ⁇ nströmung the Rotorka ⁇ channels.
- a rotor is designed in several parts, wherein a rotor part with rectilinear rotor channels is provided at its end faces with one or two inflow and in the inflow the channel flows are comparatively inlet openings and / or downstream channel beginnings
- Fig. 1 is a perspective view of a rotor according to the prior art in the form of US 6 540 487 B2, the
- Fig. 2 of Fig. 1 is a Rotorabwicklung with a speed triangle at the beginnings of the rotor channels
- Fig. 3 shows a new shape of an inlet opening of a rotor channel
- Fig. 4 shows a rotor analogous to FIG. 3 in a multi-part design.
- Figure 1 shows a perspective view of a cylindrical rotor 1 according to the prior art in the form of US 6 540 487 B2.
- rotor channels 2 with a trapezoidal cross-section, extending between the rotor channels 2 radially verlau ⁇ fende and formed as webs wall surfaces 3.
- openings 5 of the rotor channels 2 have at their radially outer corners additional rounding in the manner of diagonally outwardly widening inclined surfaces, whereby each opening is slightly increased.
- FIG. 2 On the representation of a housing surrounding the rotor and its connections for the lines and the representation of the flow-passing transitions from the housing to the rotor has been omitted.
- FIG. 2 the development of the rotor 1 of the pressure exchanger according to the prior art shown in FIG. 1 is shown.
- the speed triangle consisting of the velocity vectors U, w and c is drawn for a liquid flowing into the rotor 1, the arrows indicating the directions and the magnitudes of the different speeds.
- the flow to the rotor 1 is guided by a housing part, which is not shown here, opposite the rotor, so that the flow hits the rotor 1 in the stationary reference system as an absolute flow c at the angle a.
- the rotor 1 rotates at the peripheral speed U and, accordingly, the relative flow w arrives at it at the angle .beta.
- the circumferential component c u of the abso ⁇ lutströmung c is greater by ⁇ c u than the peripheral speed U of the rotor and thus ensures the necessary drive torque of the rotor first
- FIG. 3 shows, as development of a new rotor shape, the shaping 8 of the rotor channels 2 at their entry area and starting from the front side 4.
- the hearing speed triangle corresponds in size and direction to that according to the prior art of FIG. 2; All corresponding representations of the Geschwin ⁇ dtechniksdreiecke in the figures assume the same operating conditions.
- the shape of the rotor channels 2 in the inlet region 9 of the rotor 1 is designed by means of a shaping 8 such that the rotor inlet edges 11 with their following wall surfaces 3 do not run perpendicular to the front side 4 but under an angle and analogous to the flow angle ß of the relative inflow w.
- the relative inflow w is tangential to the rotor entry edges 11.
- the subsequent deflection of the flow in the shaping 8 and in the direction of the channel axes or in the direction of the channel length L takes place on the first 20-30% of the total channel length L.
- a transition 9 takes place in the subsequent normally formed, axially extending channel shape and is designed so that a uniform, homogeneous velocity profile 13 is ensured in the rotor channel 2.
- the rotor speed in this design of the entry of a rotor channel shape depending on the volume flow always sets so that the state of the bumpless flow is ensured for each operating point.
- FIG. 4 shows a design of the openings 5 of the rotor 1 that is simplified in comparison with FIG. 3 in terms of manufacturing technology.
- the end face 4 of the rotor 1 is included the openings 5 as a component of a separate component in the form of a Ein ⁇ strömplatte 14 is formed.
- the inflow plate 14 with the shapes 8 for a bumpless entry of the relative flow into the rotor channels 2 is applied to the rotor core 1.1 provided with axially running rotor channels 2.
- These inflow plates 14 can be mounted on one or both sides of a rotor with axially extending rotor channels. This is done according to the structure of the pressure exchanger.
- known connection techniques can be used depending on the materials used.
