Definitions

  • the invention relates to a device for separating the electrically charged particles present in a fluid from the fluid and for separating the particles by means of an electrical and by means of a magnetic field, through which the fluid with the electrically charged particles is moved.
  • a device for separating the electrically charged particles present in a fluid from the fluid and for separating the particles by means of an electrical and by means of a magnetic field, through which the fluid with the electrically charged particles is moved.
  • a device for separating the electrically charged particles present in a fluid from the fluid and for separating the particles by means of an electrical and by means of a magnetic field, through which the fluid with the electrically charged particles is moved.
  • the electrically charged particles are attracted to either the positive or the negatively charged electrode depending on their polarity.
  • the attraction of the electrically charged particles is not only dependent on the field strength of the electric field, but also on the flow velocity of the fluid and thus of the electrically charged particles transported with the fluid.
  • the negatively charged particles are not separated from one another or the positively charged particles are not separated from one another, so that separate recovery of the individual elements of the electrically charged particles is hardly possible.
  • GB-PS 13 49 995 describes a particle separation device in which also a electric field and a magnetic field are combined.
  • the electrodes for generating the electrostatic field are designed as concentric rings, which are provided concentrically on the bottom of a housing to an inlet opening of the device.
  • the magnetic device for generating the magnetic field has two cores which are surrounded by an excitation coil. The cores with the excitation coils are provided outside the housing of this device.
  • This device is not intended to separate particles conveyed by a fluid from the fluid and separate them in the device, but rather to load a particle stream into the device and to separate the different particles from one another in the device.
  • the particle mixture entering the device forms an electrically conductive gas there, as described on page 2, lines 114 and 116 of GB-PS 13 49 995.
  • the invention has for its object to provide a device with which a selective separation of the charged particles present in a fluid is possible, the various particles in the device being separated from the fluid at separate locations and being recoverable.
  • the electrodes can be arranged outside the throughflow device so that they are not attacked by the fluid.
  • the throughflow device is made of a material by which the electric field is not shielded. If the gaseous or preferably liquid fluid has no aggressive components, it is possible to arrange the electrodes in the interior of the throughflow device.
  • the flow-through device can be tubular, cylindrical, prismatic or any other design.
  • the magnetic device is designed as a coil which is arranged coaxially with the throughflow device.
  • a coil can be arranged in a simple and space-saving manner on the throughflow device.
  • the magnet device has two coils which are arranged one inside the other.
  • the outer coil is preferably arranged on an outer tube which has recesses in its outer surface
  • the inner coil is preferably arranged on an inner tube which is arranged concentrically with the outer tube
  • the outer tube and the inner tube are preferably arranged upright in a housing, wherein that forming an overflow Inner tube is connected to a drain line and the outer tube is connected to an inlet line.
  • the recesses in the outer tube of a device of the type according to the invention can be covered with a filter element.
  • This filter element can, for example, be a filter cloth.
  • the electrodes for generating an electrical field are preferably arranged radially outside the outer tube. In this way, the individual turns of the coil, which are preferably at a certain distance from one another, only slightly impair the electrical field present between the electrodes.
  • a plurality of throughflow devices can be arranged standing next to one another, the outflow line of an inner tube being connected to the inflow line of the adjacent throughflow device.
  • a diaphragm wall can be provided between adjacent flow devices. With such an arrangement of the device it is possible that certain chemical elements bypassing the normal flow path, i.e. bypassing the inflow and outflow line of adjacent flow devices can be transported directly through the diaphragm wall.
  • the outer coil has a material cross section that is different from the material cross section for the inner coil. In this way it is possible to set the magnetic field strength as desired depending on the wire cross section of the coils, as a result of which the migration of the electrically charged particles is either accelerated or slowed down as desired. This also makes it possible to further improve the selection of the various electrically charged chemical elements.
  • the traveling speed of the electrically charged particles caused by the electric field can be increased or optionally reduced by the magnetic field that is effective in addition to the electric field, so that the individual particles of different chemical elements or compositions can be used as desired Fluid can be directed through and separated from the fluid at a desired location.
  • the fluid is in particular a liquid, for example a wastewater loaded with particles to be separated out.
  • FIGS 1 and 2 show a housing 10 through which two flow devices 12 and 14 are determined.
  • a wall 16 with a diaphragm 18 is arranged between the two throughflow devices 12 and 14.
  • the throughflow device 12 has an inner tube 20 and an outer tube 22 coaxially surrounding the inner tube 20.
  • the outer tube 22 is arranged tightly between the bottom 24 and the cover 26 of the throughflow device 12.
  • the outer tube 22 has recesses 28 in its central region, through which the inner space 30 between the inner tube 20 and the outer tube 22 with a collecting space 32 surrounding the outer tube 22 is fluid connected is.
  • a filter element 38 is arranged on the outside of the outer tube 22 and covers the recesses 28 of the outer tube 22.
  • This filter element 38 is designed as a filter cloth.
  • Reference numeral 40 designates an outer coil which surrounds the filter device and thus the outer tube 22. The individual turns of the outer coil 40 are at a certain distance from one another, so that the electrical field present between the electrodes 42 and 44 of the flow-through device 12 is hardly affected by the outer coil 40.
  • the electrodes 42 and 44 are in the collecting space surrounding the outer tube 22 32 arranged and electrically conductively connected to connections (not shown).
  • An inner coil 46 surrounds the inner tube 20.
  • the inner and outer tubes 20 and 22 are preferably made of a plastic material.
  • the inner tube 20 is designed as a standing overflow. It is kept at a distance from the outer tube 22 by means of a spacer 48, which is designed, for example, as a perforated plate made of a plastic material.
  • Reference numeral 50 denotes a cover flange which is designed with a degassing valve 52. Another degassing valve 52 is arranged in the cover 26 of the throughflow device 12.
  • Reference numeral 54 denotes a supply line for the fluid, which opens through the floor 24 into the interior 30 of the throughflow device 12.
  • the inner tube 20 is connected to a drain line 56, which forms the feed line for the adjacent flow device 14.
  • the flow-through device 14 is constructed exactly the same as the flow-through device 12, so that it is not necessary to go into the individual parts of this flow-through device 14 again in detail.
  • an anion concentrate is formed in the collecting space 32 of the throughflow device 12 at the top and a cation concentrate is deposited at the bottom, while an anion concentrate is deposited at the bottom in the outer space 32 of the throughflow device 14 and a cation concentrate is deposited at the top.
