Definitions

  • the invention relates to a method in which using the electrostatic Charging and separation of difficult to separate particles within or several areas or fields are removed from a gas fluid and only one only high voltage supply source is used for this high voltage field. This applies in particular to those particles that are due to their physical / chemical Condition of the otherwise highly efficient deposition in a usual Some or most of the electrostatic filters that work on the Cottrell principle revoke.
  • the electrostatic filters are used As is known, charging and transport of the particles to be separated and their Accumulation on possibly specially shaped precipitation electrodes simultaneously in an electric field, whereby the particles after sufficient accumulation or Agglomeration either by mechanical vibration (dry cleaning) or be removed from the precipitation electrode by rinsing (wet cleaning). If necessary, several of the electrical fields described above are in series or also connected in parallel to achieve the desired total separation performance.
  • the cause of the problem of particles that are difficult to separate can be attributed to both electrical properties of the particles due to their chemical / physical condition at the precipitation electrodes to a lead insulating layer and / or that due to the electrical Flow turbulence or the so-called electric wind at high current density as a result of gas ionization in the area between the charging and separating electrodes in particular the proportion of particles in the grain size ⁇ 10 ⁇ m is becoming increasingly difficult the precipitation electrodes must be attached. It is known that as a result of physically effective charging mechanisms, namely the so-called shock or Field charging and diffusion charging, a more or less pronounced Minimum particle fraction separation performance occurs.
  • the invention has for its object the disadvantages of the above To avoid electrostatic precipitator procedures and to develop a procedure in which with the help Only one high voltage source in each electrical field can efficiently charge the Particle is carried out and subsequently the transport of the charged particles and their deposition on the oppositely polarized deposition electrodes sufficiently high field strength occurs.
  • This object is achieved in that the fluids to be cleaned within the High-voltage field are ionized and deposited in succession, the Field strength of the ionization area is smaller than the field strength of the deposition area is.
  • the efficient charging of the particles is achieved when high voltage is applied performed, which generates a field strength in the subsequent separation area, which for the transport and separation of the particles is sufficient.
  • the electrical separation method according to the invention is in practically all types of electrostatic precipitators or embodiments applicable.
  • Fig. 2 shows the overview of a single separation lane with a preceding one enlarged ionization lane.
  • the neighboring streets are not shown.
  • a High-voltage power source 1 is connected to a high-voltage system 2, which current-intensive spray electrodes 6 and voltage-intensive or low-current Spray electrodes 7 is provided.
  • the spray electrodes 6 are in one Ionization region 4, which is formed by precipitation electrodes 3.
  • the Spray electrodes 7 are located in a separation area 5, which is grounded Precipitation electrodes 3 is formed.
  • At 11 is the entire high voltage field featured.
  • the ionization region 4 and the deposition region 5 are geometric so designed that the spraying distances in the ionization area are greater than that Spraying distances in the separation area. In the enlarged ionization area 4 sufficient particle charge is achieved, which is then in the following Separation area 5 with reduced turbulence or almost no electrical Wind can be optimally separated.
  • the ionization region 4 and the deposition region 5 can be another Ionization area 4a are connected downstream with a separation area 5a.
  • Fig. 4 shows a schematic representation of a horizontally arranged electrostatic filter.
  • Precipitation electrodes 3 are provided, several in the deposition area 5
  • Form Abscheidegassen 13 In each of these separation lanes are tension-intensive Spray electrodes 7 are provided. Seen in the direction of flow of the fluids to be cleaned, are each an ionizing area 4 with the current-intensive spray electrode 6 with the Spray electrodes 7 two separation lanes 13, connected downstream. Dotted lines 14 indicate that further alleys 13 can follow.
  • FIG. 5 shows a further exemplary embodiment, according to which one ionization region 4 has three Alleys 13 are connected downstream. So here the gas is in an ionization range charged and deposited in three lanes within the separation area 5.
  • this embodiment shows that the ionizing area 4 is another Ionization area 4a is connected downstream with a separation area 5a.
  • FIG. 6 shows an exemplary embodiment with an ionization region 4, in which the grounded precipitation electrodes 9 are shown as a hollow body by a Coolant 10 are flowed through. With this cooling, a re-ionization avoided due to an extreme electrical particle resistance.
  • Fig. 7 shows the embodiment of a vertical single-field tube filter.
  • a plurality of tubes 17 between an inlet housing 15 and an outlet housing 16 provided that have an enlarged cross section 18 in the entrance area.
  • On the high-voltage power supply 1 is an isolator 19 that High voltage system 2 connected.
  • the enlarged pipe cross section 18 also forms the current-intensive spray electrodes 6, the ionization region 4 and the tubes 17 form the deposition area 5 with the voltage-intensive spray electrodes 7 Tubes 17 with the enlarged cross section 18 simultaneously form the grounded ones Precipitation electrodes.
  • the essence of the invention is clearly shown, namely within a high voltage field 11 with only one high voltage current source 1 in in an enlarged ionization area 4 to achieve optimal charging and then in the subsequent smaller individual lanes the particles from the fluid to be cleaned to separate.
