Definitions

  • the invention relates to a method for changing the swirl movement of a fluid in the swirl chamber of a nozzle and a nozzle system for performing the method.
  • nozzles are used in particular in industrial burners, oil burners and plants used for flue gas washing and spray drying of food.
  • the liquid throughput that is atomized can be kept constant, although the entry speed of the liquid into the swirl chamber can be changed and thus the swirl strength and consequently the drop quality can be adjusted.
  • the disadvantage of this solution is the need to circulate liquid.
  • the control range of the spill-return nozzles is limited. There is a significant change in the beam angle over the desired control range.
  • So-called “duplex nozzles” (DE-PS 893 133 and US-PS 2,628,867) are also known, which are used for atomizing fuels.
  • the nozzles have a swirl chamber into which the fuel is introduced via several tangential feed channels and is set in rotation about an axis.
  • the nozzles can have different cross-sectional areas at the connection point to the swirl chamber and the tangential feed channels are connected to separate feed lines.
  • a valve is integrated into one of the supply lines within the nozzle, which valve is opened as a function of the upstream pressure in the other supply line and enables a larger amount of fuel to be supplied.
  • the disadvantage of the "duplex nozzles" is, above all, that they can only be used to implement a limited regulating or control option depending on the form or throughput.
  • US Pat. No. 4,796,815 describes a shower head for a hand shower, in which the incoming water flow is introduced into a swirl chamber via two tangential and two radial channels, in which there is also a rotatable ball.
  • the water supply in the shower head can be changed by means of an adjustment element that can be operated by hand, either the water entry into the tangential channels or into the radial channels is covered, or the radial and tangential channels are only partially covered. Different spray patterns are obtained through these adjustment options.
  • the disadvantage of this shower head is that the adjusting element is arranged within the swirl chamber in order to produce different spray patterns and through this the entry surfaces of the tangential or radial channels are changed.
  • the application of this shower head is essentially limited to the sanitary area.
  • DE 39 36 080 C2 discloses a method for varying the peripheral speed component of the swirl flow of a fluid at the outlet from a swirl nozzle with a swirl chamber with several tangential feeds.
  • the entire material flow of the fluid is divided by division into at least two partial flows, the size of at least one partial flow being changeable.
  • the partial flows are fed to the longential feed channels of the swirl chamber.
  • the disadvantage is that the control range that can be achieved depends on the number of feed channels, so that the manufacturing effort for the nozzles increases with a high control range. Although a rotational symmetry of the flow is achieved, the control range remains small.
  • the known nozzles for industrial burners have the disadvantage that the burner output must be kept constant, because otherwise undesirable pollutant emissions occur, especially if the throughput is changed. Often you use several nozzles, whereby optimal conditions can only be achieved for one operating case.
  • the invention was based on the object of an improved method for changing the swirl movement of a fluid in the swirl chamber of a nozzle to create the allows to operate a nozzle with a large control range and thereby if possible a comparable drop quality (average drop diameter and Drop distribution), i.e. Ways to create the middle To be able to regulate the drop diameter at a constant volume flow or at Regulation of the volume flow to keep the drop spectrum constant. Furthermore should a suitable nozzle system for performing the method can be created.
  • the term fluid also means mixtures of different fluids with or without solids.
  • the control options for various nozzle applications created by the new procedure lead to improved productivity of the production systems and to a considerable reduction in costs.
  • the cross-sectional areas should differ by more than four times.
  • the liquid throughput is divided into several partial flows which have different cross-sectional areas. The decisive factors are the cross-sectional areas when the liquid enters the swirl chamber (connection point between the feed channel and the swirl chamber), since the peripheral speed at the periphery of the swirl chamber is determined at this point.
  • the partial flow with which the feed channels having the smallest cross-section are applied is to be increased and vice versa.
  • Intermediate values can be set continuously.
  • the simplest way of influencing the throughput of a partial flow is to use a valve.
  • the other aim for which the method can be used is to maintain a certain swirl strength at the exit from the swirl chamber.
  • the ratio of the sum of the cross-sectional areas of the supply channels that are acted upon under full load and the sum of the cross-sectional areas of the supply channels that are acted upon under partial load is to be selected at least as large as the desired ratio of the volume flows under full load and under partial load.
  • the principle of the drain control according to the invention can be used when atomizing liquids in single-substance and two-substance nozzles, in which either the liquid or the gas or both are provided with a peripheral speed in the nozzle.
  • the application is such that the method is applied to both the liquid or the gas or both. It is thus possible to influence the drop quality in two-component nozzles without changing the ratio of liquid throughput / gas throughput. It is irrelevant for what purpose the liquid is atomized. This can be done, for example, for the subsequent drying of a suspension in the drying tower. Oil can also be atomized, which is burned at the nozzle outlet, as is usual with burners.
  • the fluid can also be a gas.
  • the new system makes it possible to adapt it during operation and even regulate it by continuously measuring the product parameters. Changes in product parameters caused by nozzle wear can be compensated for over a certain period of time, thus extending the period of use of the spray tower.
  • the invention in the field of oil combustion, it is possible to drive a wide load range without a return line without changing the jet angle with a practically constant drop size. This affects the effectiveness of the entire heating system and the service life of the boiler, since the burner does not have to be started and shut down frequently when the heat requirements fluctuate.
  • the method according to the invention can also be successfully used in gas and coal dust burners, above all to influence the flame shape of the burner. When the invention is applied to fuel atomization in turbines, a reaction to different operating requirements becomes possible.
  • the nozzle shown in Figure 1 consists of the nozzle body 1 and the cover or nozzle plate 2 arranged on the outlet side of the nozzle.
  • two feed lines 5a and 5b are arranged above the swirl chamber 3, which are spaced apart in the axial direction and whose inlet openings are offset by 90 °.
  • the feed lines 5a and 5b run horizontally spaced from the nozzle plate 2.
  • the openings of the feed lines 5a and 5b are connected via separate lines 8, 9 to a central line 10 for supplying the total fluid flow F G (FIG. 5).
  • a feed pump 11 is integrated in line 10.
  • a valve 7 is integrated in the line 8 branching off from the line 10, which is connected to the supply line 5b, as a control element.
  • the nozzle outlet opening 6 which is located on the central axis of the nozzle and is connected to the swirl chamber 3 located above the cover plate 2, is incorporated (FIGS. 2 and 3).
  • the swirl chamber 3 has a constant height and has a diameter which is five times the diameter of the nozzle outlet opening 6 in the cover plate 2.
  • Four tangential feed channels 4a, 4b, 4c and 4d open into the swirl chamber 3 and each have the same height at the connection point to the swirl chamber 3.
  • the respective opposite channels 4a and 4c or 4b and 4d are connected to the feed lines 5a and 5b via vertically arranged channels 4a ', 4b', 4c 'and 4d'.
  • the feed channels 4a and 4c which have the same cross section at the connection point to the swirl chamber, are connected to the feed line 5a via the vertical channels 4a 'and 4c'.
  • the definition of the "cross-sectional area" is discussed in more detail below.
  • the feed line 5b is connected via the vertical channels 4b 'and 4d' to the tangential feed channels 4b and 4d, which likewise have the same cross section at the connection point to the swirl chamber 3.
  • the feed channels 4a or 4c and 4b or 4d differ in their cross-section at the connection point to the swirl chamber 3, the feed channels 4a and 4c have a smaller width than the feed channels 4b and 4d.
  • the offset radial arrangement of the individual feed channels, with respect to their central axis, by 90 ° in each case, was chosen because of the symmetry of the flow of the fluid into the swirl chamber 3. The method and the device are explained together with regard to reaching the control range. First of all, the case is considered that the droplet quality should remain largely uniform with a variable total throughput. This is a requirement for oil burners, for example.
  • the total liquid throughput F G is divided over all tangential feed channels 4a, 4b, 4c and 4d by forming the tangential partial flows T t1 , T t2 , T t3 and T t4 .
  • This is done by dividing the total fluid flow F G into two partial flows T 1 and T 2 , with which the feed lines 5a and 5b are acted upon.
  • the partial flow T 2 with which the tangential feed channels 4b and 4d are acted upon, that is to say the tangential partial flows T t2 and T t4 (FIG.
  • the valve 7 can be influenced by a control of the valve 7, ie the throughput of the tangential partial flows T t2 and T t4 can thus be controlled.
  • the liquid flow T 1 is divided into the tangential feed channels T t1 and T t3 .
  • the total throughput drops in the partial load case.
  • the partial flow T 2 in the partial line 8 which supplies the tangential supply channels 4b and 4d via the supply line 5b, is throttled by means of the valve 7.
  • a larger throughput T t1 and T t3 thus reaches the tangential feed channels 4a and 4c.
  • the entry speed in these feed channels increases there despite the decreasing total throughput and thus leads to a constant swirl movement at the outlet opening 6 of the nozzle.
  • the lowest limit of constant droplet quality is reached when the total throughput is only passed through the feed channels 4a and 4c and the feed channels 4b and 4d are no longer acted upon. If the total throughput drops even more, an increase in the average drop diameter can be expected.
  • the second case which can be treated with the method according to the invention is the control of the drop size with a constant throughput. The sub-streams are divided in the same way as in the first case. If the droplet size is to be reduced at the same throughput, the partial flow which supplies the feed line 5a is to be increased. The total throughput is to be kept constant by means of an appropriate circuit. If a larger drop size is required, the opposite procedure must be followed. FIG.
  • FIG. 6 shows another variant of a nozzle in an exploded view, with three tangential feed channels.
  • the nozzle is shown in two views, view a as a vertical arrangement of the nozzle and view b as an arrangement inclined around the central axis.
  • the nozzle consists of the base or nozzle body 1, the swirl body 12, the cover or nozzle plate 2 and the cap 13 which is screwed onto the nozzle body 1.
  • the feed lines 5a and 5b are not arranged horizontally but vertically in the nozzle body 1.
  • FIGS. 7 and 8 show two different design variants of the swirl body 12, each as a top view a and a bottom view b.
  • the swirl body 12 according to FIG. 7 is identical to the swirl body shown in FIG. 6.
  • the swirl body 12 according to FIG. 8 is only equipped with two tangential feed channels 4a, 4b.
  • View a shows the top view and view b the bottom view.
  • FIG. 7 shows the variant shown in FIG.
  • the partial fluid flow T 1 flowing through the supply line 5b is divided into two tangential partial flows T t2 and T t4 and the other partial flow T 2 reaches the tangential supply channel 4a without further division.
  • the partial streams T 1 and T 2 are not further divided and fed to the swirl chamber 3 via the respective associated tangential feed channel 4a or 4b.
  • FIG. 9 shows an enlarged top view of a swirl chamber 3, into which two tangential feed channels 4a and 4b open. At the connection point to the swirl chamber 3, the two feed channels 4a and 4b have different cross-sectional areas.
  • the tangential feed channels of a nozzle have the same height at the connection point to the swirl chamber 3 and, if necessary, can have different widths, as illustrated in FIG. 9 by the width dimensions B 1 and B 2 .
  • the respective width dimension is the distance between two on a parallel line lying on the center axis M intersection points S 1 and S 2, wherein the intersection point S 1 is the intersection between the lateral surface of the swirl chamber and adjacent to this wall of the tangential feed channel and the point of intersection S 2 the intersection of the parallel line with the opposite wall of the tangential feed channel.
  • the connection point of the tangential feed channels to the swirl chamber can also be designed as a circular cross-section, in which case different cross-sectional areas can be achieved in an analogous manner at this point through different diameters of the respective bores. It is also clear from FIG. 9 that the tangential feed channels 4a and 4b can be designed differently outside the connection point to the swirl chamber, e.g.
  • a nozzle is designed with a plurality of tangential feed channels, it is expedient if these are distributed uniformly over the circumference or the inner lateral surface of the swirl chamber. It has proven to be advantageous if the swirl chamber and the cross sections of the tangential feed channels at the connection point to the swirl chamber are dimensioned according to a certain ratio, as follows: 2 B D 2 - D 1 ⁇ 0.5 where B is either the width or the diameter of the channel at the point of connection to the swirl chamber and D 1 or D 2 are the diameters of the outlet nozzle or swirl chamber, as explained above. In a manner known per se, the swirl chamber has a smaller dimension than the diameter.
  • 11 to 13 show different circuit arrangements for different design variants of the nozzles.
  • the control intervention in the throughput of the fluid flow outside the nozzle is carried out either via a valve or separate pumps.
  • Control means all intervention options that affect the throughput of the fluid flow, such as throttling by valves, influencing the pump characteristic of a pump by changing the speed of the pump or the like.
  • the further division of the total fluid flow F G into further partial flows T 1 , T 2 etc. can be anticipated either inside or outside the nozzle.
  • the partial flows T t1 to T t4 are always fed into the swirl chamber tangentially. In the embodiment shown in FIG.
  • the total fluid flow F G conveyed by a pump 11 is divided into two partial flows T 1 and T 2 , and each via a tangential feed channel T t1 and T t2 , which differ at the connection point to the swirl chamber 3 of the nozzle 14 Have cross-sectional areas supplied to the swirl chamber.
  • a valve 7 is integrated in the line for the partial flow T 2 , which is connected to the tangential feed channel with the larger cross-sectional area at the connection point to the swirl chamber.
  • This basic variant causes the least effort in terms of production.
  • the case with constant fluid flow is discussed.
  • the liquid is supplied via a line and two sub-streams are formed by branching.
  • the size of one partial flow can be limited by a valve. After the valve, it is fed to the feed channel with the larger cross-sectional area.
  • the two limit cases exist when the valve is fully open or closed. When the valve is fully open, the liquid throughput is distributed over both supply channels.
  • the peripheral speed at the inner surface of the swirl chamber has its lowest value and thus the peripheral speed at the nozzle outlet is also the lowest.
  • the circumferential speed at the nozzle outlet takes on the greatest value when the valve is closed.
  • the ratio of the smallest cross-sectional area to the total cross-sectional area of both feed channels determines the ratio of partial load to full load that can be achieved and at which the atomization properties do not change essentially.
  • the circuit variant shown in FIG. 11 corresponds to the nozzle shown in FIG. 6 with a swirl body 12 according to FIG. 8.
  • the circuit variant shown in FIG. 12 differs from the circuit variant shown in FIG. 11 only in that the partial stream T 2 is not divided into a tangential partial stream but into three tangential partial streams T t2 , T t3 and T t4 , the sum of which consists of the cross-sectional areas of the tangential feed channels at the connection point is larger than the analog cross-sectional area for the tangential partial flow T t1 .
  • the configuration of the nozzle is analogous to that in the embodiment according to FIG. 12.
  • the difference is that there is no branching off of a total fluid flow, but two separate partial flows T 1 and T 2, independently of one another, via lines integrated in the lines Eccentric screw pumps 11, 11 'are influenced by a change in the speed of the pumps.
  • eccentric screw pumps 11, 11 ' are used in each partial flow, the throughput of which is adjusted via a change in speed.
  • the present invention can also be used in cases where it is necessary to keep the jet angle of the fluid emerging from the nozzle constant at different throughputs, that is to say to influence the control of the jet angle.
  • a larger jet angle is achieved with increasing throughput.
  • the beam angle is also increased with increasing total throughput. The following situation arises when using the circuit variant according to FIG. 11.
  • the total throughput can be increased by opening the valve. This increases the beam angle slightly. So if you lower the delivery pressure when the valve is closed, you get a constant jet angle.
