Definitions

  • the invention relates to an electrostatic dust separator with one or more electrical fields in a housing which is provided at one end with a raw gas hood and at the other end with a cross-sectionally reduced clean gas hood with subsequent clean gas line, the lower part of the clean gas hood having an additional exhaust nozzle , which is assigned an opening in the floor of the clean gas hood.
  • Such separators are used to remove dust particles from gases, especially industrial gases.
  • the electrical fields forming the deposition zone consist of alley-shaped precipitation electrodes with high-voltage electrodes in between. If the gases are passed through the separation zone, the gases are divided into a low-dust and a partial flow enriched with dust particles. The gas velocities within the dust separator lead to the partial stream enriched with dust particles settling in the lower region of the gas stream and being transported there to the outlet.
  • the invention has for its object to collect the dust in the clean gas stream without turbulence and to pass it on together with the gas portion.
  • This object is achieved in that the opening in the bottom of the clean gas hood is covered with a peeling plate covering this, which forms a gas-tight cavity with an inlet opening with the side walls and the bottom.
  • a targeted suction of a small but relatively high dust-laden gas stream can be made possible.
  • This targeted suction is particularly effective if the opening is provided immediately before the clean gas line is connected. This means that the opening is in the upper area of the floor panel.
  • the dust particles located in the area of the base plate within the gas flow migrate undisturbed, ie without swirling, into the cavity formed by the peeling plate. From here, the partial flow of the gas can be brought to a desired degree of purity in a known manner via a more or less intensive partial flow dedusting and into the pure gas can be discharged. A recycling of the non-dedusted portion into the raw gas is also conceivable.
  • the amount of partial electricity to be extracted can be chosen to be relatively small due to the arrangement of the peeling plate according to the invention. For example, do not correspond to the average speed which would correspond to the opening below the edge of the peeling plate, because the inertial forces of the dust particles to be captured can also be used in this area.
  • the peeling plate is movably arranged to change the inlet opening.
  • the peeling plate In order for an almost gas-tight cavity to form, the peeling plate must be connected to the side walls by suitable means and held in detents. The quantity to be extracted can thus be varied.
  • An electrostatic dust separator 1 consists of a housing 2 with hoods arranged on the side, which are designed as raw gas hood 4 on the gas inlet side and as clean gas hood 5 on the gas outlet side.
  • a raw gas line 3 is connected to the raw gas hood 4 and a clean gas line 6 is connected to the clean gas hood 5.
  • Below the housing 2 there are dust collection bunkers 7 from which the separated dust is drawn off.
  • a plurality of electrical fields 8-10 are provided within the housing 2, each of which is formed from precipitation and high-voltage electrodes, which are not described in greater detail.
  • the reinhaha hood 5 is formed from the floor 11, the two side walls 12 and 13 and the ceiling 14.
  • a rectangular clean gas line 6 connects to the hood 5 at.
  • the opening 15 is covered by a peeling plate 17, whereby a cavity 19 is formed in connection with the side walls 12 and 13 and the bottom plate 11, which only leaves an opening 20 for the entry of the partial gas flow.
  • the peeling plate 17 can be arranged adjustable in height. Hinges 23 and detents 18 are provided for this purpose. So that a largely tight seal with the side walls 12 and 13 is ensured even when the peeling plate 17 is movable, the side surfaces of the peeling plate can be provided with elastic means, for example sealing strips.
  • elastic means for example sealing strips.
  • FIGS. 8 and 9 show two further configurations, the clean gas hood according to FIG. 8 being arranged conically and merging into a round clean gas line 6.
  • the peeling plate 17 is provided in the region of the lower edge 6a of the channel 6.
  • the peeling plate 17 is pulled up to approximately the middle 6b of the tube 6 and adapted to the duct cross section.
  • the clean gas hood 5 a rectangular inlet cross-section and a round outlet cross-section.
  • a segment-shaped peeling plate 17 is also provided here. With the dashed areas 24, the inlet area for the partial gas flow is shown. By adjusting the peeling plate 17, these areas can: be adapted to the respective flow or dust distribution requirements.
  • control can be designed, for example, in such a way that the lower gas stream laden with dust particles is measured and the position of the peeling plate is adjusted on the basis of the dust loading.
