Definitions

  • This invention relates to apparatuses for removing dust and other foreign bodies from dustladen air, flue-gases or the like and is particularly adapted for use 'in power plants, boiler- 5 houses, etc.
  • the invention shows how these usual methods of dust-collecting may be improved by making use of a secondary gas-current, which always pro- 20 ceeds from the main current, when gases (or fluids) are forced to-follow a curved path and which secondary gas-current is known as the double eddy-current (German Doppelwirbel).
  • the primary object of this invention is to provide for utilizing double eddy currents in securing high efliciency 30 in dust removing devices.
  • the influence of the double eddy-current upon the path of the dustparticles is shown in the following drawings and description.
  • Figure 1 is a diagrammatic vertical sectional 35 view of a concentrator illustrating the formation of double eddy currents.
  • Figure 2 is a diagrammatic horizontal view of the construction shown in Figure 1.
  • Figure 3 is a diagram illustrating the path of 40 the dust laden gases in the planes III-III of Figure 1.
  • Figure 4 is a diagram illustrating the path of flow of the gases on the line IVIV of Figure 1.
  • Figure 5 is a vertical sectional view illustrating '45 the application of the principles of the invention to one form of embodiment.
  • Figure 5a is a vertical half-sectional view similar to Figure 5 but showing a modification of the casing.
  • Figure 6 is a horizontal cross-sectional view taken on the line 6-6 of Figure 5.
  • Figure 7 is an elevation, partly in section, showing a construction embodying the invention.
  • Figure 8 is a horizontal sectional View of the 55 construction shown in Figure '7,
  • the double eddy-current in a. curve The Figures 1-4 show the double eddy-current in a hollow annulus l, The main current is indicated by the arrows 2 in Fig. 2.
  • the arrows 3 and 4.in Fig. 1 indicate the two halves of the double eddy-current. 0n the right side of this figure the streamlines of the two halves of the double eddy-current are shown.
  • the dust-particles in the middle of the chan- 10 nel I are carried along to the periphery of the annulus by the gas-current of the double eddy-' current, which has here a rather great velocity, so that the dust particles in the middle of the channel reach the periphery of the annulus in a very short time, even if they are very fine.
  • Their own velocity, due to the centrifugal action is of little importance, compared with the velocity of the double eddy-current (arrow 6 in Figs. 1 and 4).
  • the double eddy-current has nothing to do with the ordinary turbulence in the gases in rapid motion.
  • the turbulence has the tendency to level the differences in the'loading of the gases at the centre and the periphery, but as this turbulent motion is very irregular, it only levels, but
  • Fig. 1 In the left side of Fig. 1 is shown how the double eddy-current sweeps the dust-particles in the edges of the casing, so that the loading of the gases is much higher in these places.
  • the right method of skimming-017 the dust Fig. 5 shows a chimney 8 provided with a circular or volute casing 9 around it.
  • the gas-outlet with vanes new chance of being directed to the periphery.
  • the collectors have vanes 14 in the opening II, which 'are directed opposite to the main current 2 in Fig. 2. These vanes H are very clear to be seen in Fig. 8. By the very sharp curve of the gases the dust particles are thrown outwards and collide with the vanes' H. After that, they are carried along with the current 6 and may reach the slot 10.
  • a diagram shows the loading of the escaping gases as a function of the place of outlet.
  • the linesli-BC-D show the relative loading of the passing gases.
  • the loading in the middle part BC is much less than the loading in the edges.
  • the greater area of the parts ABGH and CDEF,compared with BCFG shows the gain in eflicienoy', forthe cleaner the gas in the outlet, the higher the eillciency. Without vanes, or with vanes in the same direction as the gas current, this result would not have been obtained, for it is necessary that the dust-particles come into collision in the middle part of the collector-outlet.
  • Line KL shows the loading of the gases when the outlet H has no vanes, or vanes in the same
  • the loading depends entirely upon the'angle of the vanes; the more the vanes are directed tangentially, or the sharper the curvature of the annulus and the more the dust collides, the lower is the loading
  • the placing of vanes ll in the opening II is also known, but when directed forwardly to decrease the resistance of the collector they decrease also I the efliciency of the dust-collecting. Even the directing of the vanes opposite the gas-current 2 is known, but what has not been known heretofore is that the greatest advantage is only obtained when the vanes I4 are directed as last'mentioned and placed in that part of the collector where the double eddy-current 3 and I (Fig. 1) has a velocity 6 to the periphery which carries along the particles after collision.
  • the emciency increases with the number of the vanes. It is desirable to make the vanes l4 so that they may be pivoted or turned round their axes. In the collector, shown in the Figs. 7 and -.8. this brings the possibility of adaptation of the angle of the vanes to the boiler-load. At peakload the vanes are opened very wide and then the resistance of the collector is even less than it would be without any vanes. At the same resistance, the collector could be smaller, which is not only cheaper, but has also. the advantage that the velocity of the main current at the lower loads will be suilicient to separate the dust from the gas. With the lower load the vanes are more nearly shut and their separating action increases. This neutralizes the loss of dust-collecting efllciency by the lower velocity of the main current, so that a constant emciency at very diflerent loads may be obtained by the use of pivoted vanes.
  • Dust-collecting gutters In many cases one can make use of the property of the double eddy-current to sweep the dust into .the corners of the casing (Fig. l).
  • Shunt-type collector A dust-collector in which are embodied many of the improved constructions which have been heretofore described is shown in the Figures 7 and 8.
  • the dust-laden gases enter at 41 into the casing 9, shown in Fig. 5, with vanes Id at the outlet.
  • the skimming place I0 is U-shaped and leads to the shunt-current-cyclone 48.
  • This collector has the same efliciency as a very large direct-type cyclone and a lower resistance.
  • the pivoted vanes I4 the quantity of gases escaping to the chimney is regulated. At peak load the vanes are opened widely but at 25% load the vanes are nearly shut off, so that the cyclone 48 gets practically all the gases and is charged constantly, independent of the boiler-load.
  • This shunt-type collector has therefore a constant emciency at all loads, which is as high as that of a very good direct-type cyclone.
