Definitions

  • the invention relates to a self-supporting spray electrode in an electrostatic dust separator with plate-shaped precipitation electrodes which direct the gas flow and which consists of a one-piece, symmetrically folded metal sheet which is symmetrical to the precipitation electrodes and which is attached to a spray tab and which is attached to a carrying strap has at least two rows of spray arms arranged along the central plane between the precipitation electrodes with spray tips running in the plane of the spray arms or directed towards the adjacent precipitation electrodes on both sides.
  • the invention further relates to a method for producing the spray electrode.
  • the gas to be cleaned is passed through many parallel lanes in a housing.
  • the alleys are formed by several precipitation electrodes arranged in a row, which can reach linear dimensions of 15 m and more.
  • the spray or emission electrodes are arranged longitudinally between the precipitation electrodes.
  • the spray electrodes While the precipitation electrodes of a dust collector are usually grounded, the spray electrodes are connected to a high negative DC voltage, which can be in the range of 100 kV. An electrical force field is created between the two electrodes.
  • the electrical force concentration at the spray electrode must be large enough to generate a glow or corona discharge, which is noticeable as a strong, bluish glow.
  • the emerging electrons ionize the air and other gases that form the atmosphere.
  • the negative resulting from ionization and positive ions migrate to the electrodes of opposite polarity.
  • the migrating ions in turn collide with dust particles suspended in the gas stream, adhere to them and thereby impart an electrical charge.
  • the charged dust particles are attracted by the electrodes of the opposite polarity under the influence of the electric field.
  • the overwhelming majority of the dust particles are negatively charged; they are deposited on the positive precipitation electrode. Only 1 - 3% of the dust particles are positively charged and are deposited on the spray electrode with a negative potential.
  • the gas volume flowing through, the physical nature of the carrier gas, its moisture and temperature, the electrical resistance and the behavior of the dust in the electrical field are important for the efficiency of electrostatic precipitators.
  • the grain composition and chemical analysis of the dust, the characteristics of the effective electric field, the gas velocity, the re-whirling up of the dust when knocking, the gas composition, the current and the voltage curve also determine the traveling speed of the electrically charged particles.
  • EP-A2 0 287 137 describes two variants of spray electrodes made of sheet metal strips of the same width throughout.
  • the spray electrode is shaped into an approximately elliptical tube cross section, with longitudinal edges connected to one another in an overlapping manner. Triangular tabs are bent individually from the pipe cross-section. The tabs form on both sides of the elliptical tube cross-section, in the extension of its main axis, outward-pointing flags with alternately bent spray tips.
  • a second variant instead of an elliptical tube cross section, two wide edge strips are angled in opposite directions by a narrow center strip. The longitudinal edges of the edge strips are flanged in the same direction with the respective bend in such a way that an essentially elongated Z-shaped cross section is produced.
  • approximately triangular tabs are individually bent out of the edge strips, which are not on the central plane between the two parallel legs.
  • This embodiment of a spray electrode has the disadvantage in terms of its design that the bent tabs are limited to a length lying below the main axis of the ellipse or the width of an edge strip. Furthermore, the production seems to be relatively complex.
  • a spray electrode for electrostatic deposition which consists of a long, suspended support and cantilevered elements connected to the support to form a corona.
  • the carrier consists of a metal strip and has a stiffening extending centrally in the longitudinal direction.
  • the longitudinally stiffening has open, channel-shaped parts on both sides, for example in the form of a longitudinal wave folding.
  • This embodiment has the disadvantage that it cannot give the rigidity of a conventional tubular support.
  • only one-piece embodiments are shown which have sawtooth-like cantilevered spray tips which are arranged near the carrier.
  • the spray tips from several spray electrodes are not optimally distributed since they are arranged in the region of the carrier. Since the sheets cannot be of any desired width, a two-part embodiment of the spray electrode, with spray arms individually attached to a base body, is formed to achieve better distribution of the spray tips (FIGS. 7 and 8).
  • the present invention has for its object to provide a apart from suspension and connecting elements one-piece spray electrode of the type mentioned, which can at least give the rigidity of a conventional tubular support, has no geometric barriers for optimal design and both simple and material-saving can be produced.
  • the object is achieved according to the invention in that the metal sheet has punched, symmetrically cantilevered spray arms on both long sides and on the inside of the spray arms is bent more than at right angles out of the plane of the spray arms to form a region which is essentially continuously folded in the form of a double loop .
  • Special embodiments and further training are the subject of dependent claims.
  • the electrical conductivity of the material used to produce the spray electrodes is not of primary importance.
  • the carrier consisting of the folded metal sheet should have a mechanical strength comparable to that of a carrier tube.
  • the requirements with regard to electrical conductivity, mechanical strength and machinability are met in the case of folding according to the invention, in particular of strip steel, brass and high-strength aluminum alloys.
  • the spray electrodes must neither be caused to vibrate too much by the gas flow nor be unevenly designed due to imprecise processing. In the event of twisting or imprecise configuration, arcing can occur, which can lead to a voltage collapse. Thanks to its simplicity, the spray electrode according to the invention allows the necessary manufacturing precision without problems.
  • the double loops according to the invention in particular double triangles, bring more external mass, which results in a higher moment of inertia.
  • the simpler manufacture results from the folding with an axis of symmetry and a quasi-symmetry axis.
  • the production of the fold is not only easier, but also more precise, which has a particularly advantageous effect on the optimal position of the spray tips.
  • the suspended beam must survive the periodic knock without damage in the long term.
  • the metal sheet is preferably bent by more than 100 °, in particular by more than 120 ° from the plane of the spray arms to form the double loop.
  • the length of the spray arms running vertically to the carrier is preferably above the extent of the folded carrier in this direction. In practice, the length of the spray arms is more than twice the extent of the folded carrier.
  • the folded support of the spray electrode is symmetrical, but also the spray arms and, according to the most common variant, spray tips.
  • the folded carrier can be in the range of a quarter to three quarters, based on the distance between two adjacent spray tips projected onto a vertical to the longitudinal axis.
  • the entire spray electrode is designed in such a way that spray arms of different lengths are arranged alternately on each side of the folded carrier, so that no curvatures can occur in the longitudinal direction.
  • a spray electrode is composed of two partial spray electrodes, preferably of the same length, by screwing together two connecting lugs attached to the folded carrier. These connecting straps can simultaneously be used to arrange connecting webs running parallel to the precipitation electrodes in the horizontal direction, which prevent or at least severely restrict the suspended, very long spray electrodes.
  • the object is achieved according to the invention in that spray arms formed "in-line" from a sheet metal and slotted on the end crowns, cold-formed in the longitudinal direction on the inside of the spray arms to form the folded carrier, and in the same operation the spray tips are spread.
  • the materials used are preferably solidified. As a result, the mechanical strength of the folded carrier is increased to a desired extent.
  • FIG. 1 The partial top view of an electrostatic filter shown in FIG. 1 shows two parallel, plate-shaped precipitation electrodes 10 and hanging spray electrodes 12 arranged in a central plane E.
  • the spray electrodes 12 are suspended at regular intervals.
  • the gas flow G directed by the precipitation electrodes 10 flows in the direction of the arrows, depending on the concept of the electrostatic filter, also upwards or downwards, which is not shown visibly.
  • the spray electrodes 12 essentially consist of a folded carrier 16, spray arms 18 extending on both sides parallel to the precipitation electrodes 10, each with two terminal spray tips 20 bent in the opposite direction. These can also lie on the plane of the spray arms 18.
  • a connecting web 22 is indicated between two spray electrodes 12. This connecting web 22 connects all spray electrodes 12 at the level of connecting tabs (FIGS. 8-10), expediently halfway up, in the direction of the precipitation electrodes 10.
  • each show the upper part of a hanging spray electrode 12, which shows the principle of the arrangement of the spray arms 18.
  • the spray arms 18 are staggered on both sides of the folded carrier 16.
  • the spray arms 18 are of equal length on both sides, the spray tips 20 form two vertical rows at a distance s / 2.
  • long and short spray arms 18 are arranged alternately on each side.
  • the spray tips 20 which are at a distance s with respect to the projection onto a vertical to the longitudinal direction L of the carrier 16 are therefore on four vertical rows. According to the embodiment of FIG. 3, the spray tips 20 are distributed more regularly over a larger area.
  • the gas flow G essentially flows in the direction of the arrow, that is to say in the direction of the spray arms 18, components ascending and / or descending not being shown.
  • the spray electrodes 12 are suspended from a carrying strap 24.
  • FIG. 4 shows a top view of a metal sheet with spray arms 18 that has been folded out to form a spray electrode 12 and has been punched out beforehand.
  • a slot 28 is punched out of the front parting 19 of the molded spray arms 18, which allows the spray tips 20 to be spread mechanically.
  • the length l of the spray arms 18 is slightly more than twice the width b of the folded carrier in the same direction.
  • the approach of the spray arms 18 lies at a distance a outside of the fold. This spray approach is never bent, which significantly simplifies machine production.
  • FIG. 5 shows an enlarged side view of FIG. 4.
  • the metal sheet forming the carrier 16 is bent six times through 135 ° to form two right-angled triangles with right angles lying on the plane E.
  • the base 30, 32 of the triangles which are rectangular in cross section and have a width b, runs parallel to the plane E.
  • the metal sheet bent over three times passes through the plane E at an angle of 45 °, between the first and the last bend. Due to the cold deformation, the folded carrier 16 gains mechanical strength.
  • the spray arms 18 lie on the plane E, which is the central plane between the precipitation electrodes 10 but also between the base surfaces 30, 32 when the spray electrode 12 is mounted.
  • the spray tips 20 are spread apart, they are at a distance l from the metal sheet not punched out and at a distance l + a from the vertical projection of the carrier 16.
  • Fig. 6 shows an essentially 8-shaped fold, which merges into the spray arms 18. These in turn lie on a plane which is at the same time the tangential plane of the two folds shown in cross section as loops 34, 36. When the spray electrode 12 is installed, the tangential plane lies in the mentioned center plane E.
  • FIG. 7 shows a particularly preferred variant of the present invention.
  • the metal sheet is initially bent twice in the opposite direction by 135 ° to produce the folded region 16. Then the metal sheet is bent through 90 °, it thus runs vertically to plane E. When this level is pierced, the sheet is bent outwards by 45 °, then it is bent twice in parallel by 135 °, but in the opposite direction to the 45 ° turn mentioned, and forms the upper base surface 30.
  • the bent sheet now runs at an angle of 45 ° with respect to plane E.
  • the metal sheet On the intersection of the two levels, the metal sheet is bent outwards by 45 °, so that it runs vertically to level E.
  • the metal sheet At the level of the base line 32 of the lower right triangle formed, the metal sheet is bent by 90 ° and now runs in the plane of the base surface 32 of the lower right triangle. Finally, the metal sheet is bent twice in opposite directions by 135 °, the second time in such a way that the metal sheet is again in plane E.
  • each loop being designed as an essentially right-angled triangle.
  • the loops are in the form of right-angled triangles, with the tip in the area of plane E.
  • FIG. 7 has the disadvantage of less simple manufacture for forming the fold in a base surface, for example 32. However, this is offset by the advantage of a substantial increase in the torsional strength.
  • FIG. 8 and 9 show the principle of attaching a connecting tab 44 to the front end 46 of a spray electrode 12 according to FIG. 5.
  • the two forks 48, 50 of the connecting bracket 44 are offset from one another, as can be seen from FIG. 9.
  • a Z-shaped folded carrier 16 is inserted into a longitudinal slot 52 between the forks 48, 50. Outside the folding area, the forks 48, 50 are connected to the metal sheet of the spray electrode 12 by means of a spot weld 54.
  • the connecting link 44 On the side facing away from the forks 48, 50, the connecting link 44 is of flat design with a plane rotated through 90 °. This part shown in more detail in FIG. 10 the connecting lug 44 has a screw hole 56 and a round cam 58, 60 on the longitudinal axis of the connecting lug each at the same distance. A blind hole 62, 64, which have the same diameter as the cams 58, 60, is cut out below the cantilevered cams 58, 60.
