Definitions

  • the invention relates to a device for generating accelerated electrons.
  • inner walls of hollow bodies as well as bulk material and fluids with accelerated electrons can be charged with a device according to the invention.
  • Electron beam technology has been used for several decades on an industrial scale for the chemical modification of materials as well as for the disinfection and sterilization of surfaces.
  • the treatment of products can be economically advantageous at atmospheric pressure, for which the electrons first released in a vacuum, then accelerated and finally by a beam exit window, usually a thin metal foil, must be coupled into the treatment zone.
  • a beam exit window usually a thin metal foil
  • Electron beam sources based on thermionic emitters are also mechanically complicated, difficult to scale and require expensive high voltage power supplies and high vacuum systems. In case of damage to the jet exit window with it As a result of the resulting collapse of the vacuum irreversible damage to the cathode system and thus a high repair effort.
  • DE 199 42 142 A1 discloses a device in which bulk material is passed in multiple free fall on an electron beam device and charged with accelerated electrons. Due to the multiple pass, combined with an intermediate mixing of the bulk material, the probability in this embodiment is very high that the particles of the bulk material are charged on all sides with accelerated electrons. The multiple pass, however, requires a lot of time in carrying out the treatment process. The disadvantage here is also that the device is unsuitable for the treatment of larger moldings.
  • DE 10 2006 012 666 A1 which comprises three axial radiators with associated deflection control and three likewise associated electron exit windows.
  • the three electron exit windows are arranged in such a way that they completely surround a triangular free space. If a substrate is guided through this free space, it can be charged in its entirety with accelerated electrons in a treatment passage in its cross section. However, if the substrate does not have the same triangular cross-section as the space enclosed by the three electron exit windows, the dose distribution of the accelerated electron impingement on the surface of the substrate will be inhomogeneous. The expenditure on equipment in this embodiment is also very high, whereby this solution is also very expensive.
  • WO 2007/107331 A1 a device is known in which only two area jet generators are needed, between which a molded part for the purpose of sterilizing its surface moves through and can be acted upon while accelerated electrons.
  • This device also has a plurality of gold reflectors, which are used to reflect marginal rays emitted by the area beam generators onto surface areas of the molded part which are not in the direct area of action of the area beam generators. Since the reflectors known from this document are made of pure gold, such devices are also very expensive and thus affect their cost-effectiveness. Since reflected electrons have lower energy than non-reflected electrons, only inhomogeneous energy input into a substrate is possible with this device.
  • FIG DE 10 2013 111 650 B3 discloses in which all the essential components, such as cathode, anode and electron exit window, are annular, so that by means of such an apparatus, an annular electron beam can be formed, in which the accelerated electrons move towards the ring inside.
  • an annular electron beam can be formed, in which the accelerated electrons move towards the ring inside.
  • US 2008/0267354 A1 also describes annular devices with which a high dose of X-rays and, incidentally, electron beams can be generated. Due to the generation of a high dose of X-rays, such devices are not suitable for irradiating products entering the food chain of humans or livestock.
  • the invention is therefore based on the technical problem of providing a device for generating accelerated electrons, by means of which the disadvantages of the prior art can be overcome.
  • a device is to be created with a compact design, with which, for example, hollow body from the inside but also bulk material with accelerated electrons can be applied.
  • FIG. 1 a cross section of a device 1 according to the invention is shown schematically.
  • Device 1 initially comprises an electron exit window 2 in the form of a hollow cylinder.
  • the cylindrical electron exit window 2 is part of a housing, which has the shape of the lateral surfaces of a cylinder and which is therefore likewise cylindrical in shape as the electron exit window 2.
  • the cylindrical housing encloses an evacuable space. 3
  • the cylindrical electron emission window of a device according to the invention also comprises a mechanical support grid to which a metal foil is attached.
  • the electron exit window 2 comprises an in Fig. 1 not shown mechanical support grid made of copper, to which a titanium foil is attached.
  • a device which has the shape of a rod or a hollow cylinder and which is thus rod-shaped or cylindrical.
  • a rod-shaped electrode In the embodiment of Fig. 1 extends along the cylinder axis of the cylindrical electron exit window 2, a rod-shaped electrode 4.
  • wire-shaped electrodes 5 On a circular path around the cylinder axis of the cylindrical electron exit window 2 around, wire-shaped electrodes 5 are arranged at the same distance from each other.
  • the wire-shaped electrodes 5 extend completely or partially along the cylinder length of the cylindrical electron exit window through the evacuable space 3 and are connected as an anode.
  • the device 1 has a total of eight wire-shaped electrodes 5.
  • the number of wire-shaped electrodes of a device according to the invention is not set to eight, but in other embodiments may alternatively be less than or greater than eight.
  • the anode-connected wire-shaped electrodes of a device according to the invention preferably have a slightly positive voltage potential in the range of +0.25 kV to 5 kV with respect to the electrical ground of the device 1, whereas the cylindrical housing of a device according to the invention, including the cylindrical electron exit window and the support grid , preferably having electronic ground potential.
  • a glow discharge plasma is formed in the evacuable space 3.
  • an electric voltage of 1 kV is used to ignite the glow discharge between the wire-shaped electrodes 5 and the first cathode acting housing of the device 1, which drops to 0.3 kV after the ignition of the glow discharge to maintain the glow discharge.
  • an electrical voltage in a range of -60 kV to -300 kV can be applied to the central, rod-shaped or cylindrical electrode 4 of a device according to the invention.
  • an electrical voltage in the range of -80 kV to -200 kV is applied to the electrode 4.
  • the electrode 4 thus acts as the second cathode of a device according to the invention.
  • a device further comprises a first grid-shaped electrode 6 in the form of a hollow cylinder, which encloses the at least one second cathode 4, wherein the first grid-shaped and cylindrical electrode 6 is spaced to a smaller extent from the second cathode 4 than the wire-shaped electrodes 5.
  • Die The first grid-shaped and cylindrical electrode 6 likewise has the electrical ground potential of the device 1, shields the second cathode 4 from the plasma and thus limits the space for spreading the glow discharge plasma to the volume between the first grid-shaped and cylindrical electrode 6 and the electron exit window 2 This volume in which the glow discharge plasma propagates is also referred to below as the plasma space 7.
  • ions from the glow discharge plasma are accelerated in the direction of the cathode 4, which dissolve secondary electrons from the second cathode 4 when they impinge on the surface of the second cathode 4.
  • the secondary electrons are in turn accelerated along the field lines of the electric field perpendicularly from the surface of the second cathode 4 in the direction of the first grid-shaped and cylindrical wire-shaped electrodes 5 and finally to the electron exit window 2.
  • the surface perpendiculars of the surface region of the cathode from which electrons are emitted are aligned with the cylindrical electron exit window. Electrons which penetrate the electron exit window of a device according to the invention are thus emitted to the external environment of a device according to the invention.
  • electrons can be radiated completely outward starting from the centrally arranged second emitter acting as emitter.
  • the cylinder axis of a cylindrical device according to the invention for example, be aligned vertically and be passed around the cylinder cross-section around an annular curtain of bulk material in free fall.
  • the disadvantage here is that the bulk material can not be fully loaded with accelerated electrons in one pass.
  • this deficit can be compensated for by a multiple pass and represents an economic procedure for applying bulk material with accelerated electrons, especially in the case of small quantities of bulk material.
  • a cylindrical electron reflector is arranged around a cylindrical device according to the invention, which delimits an annular clearance between the device according to the invention and the cylindrical electron reflector.
  • an annular curtain of bulk material at the electron exit window of the device according to the invention can be passed in free fall, wherein the bulk material curtain can be at least partially also applied from the back with accelerated electrons with the electrons reflected at the electron reflector.
  • the glow discharge plasma within the device 1 is adjacent to the electron exit window 2, which is accompanied by ion bombardment of the electron exit window 2.
  • the resulting sputtering effects can cause damage to the electron exit window 2 over time and the This makes device 1 dysfunctional. Keeping the plasma ions away from the electron exit window is therefore advantageous.
  • Fig. 2 is a cross-section of an embodiment of a device 8 according to the invention shown schematically.
  • Device 8 comprises first of all all components of the device 1 from Fig. 1 with the same functionality.
  • device 8 has a second grid-shaped and cylindrical electrode 9, which encloses the at least one second cathode 4, wherein the second grid-shaped and cylindrical electrode 9 is spaced from the second cathode 4 to a greater extent than the wire-shaped electrodes 5.
  • the second grid-shaped and cylindrical electrode 9 preferably has an electrical voltage in the range of the electrical ground potential to +500 volts.
  • the plasma region 7 of the device 8 is limited to a volume between the first lattice-shaped and cylindrical electrode 6 and the second lattice-shaped and cylindrical electrode 9, through which the wire-shaped electrodes 5 extend partially or completely.
  • the electron exit window 2 of the device 8 is thus shielded from the glow discharge plasma, which prolongs the life of the electron exit window 2.
  • the electrical voltage at the wire-shaped electrodes 5 is pulsed.
  • the glow discharge plasma of a device according to the invention can be maintained at lower pressures in the evacuable space.
  • the at least one electrode 4 acting as the second cathode can also be traversed by at least one channel through which a coolant flows or flows.
  • the rod-shaped second cathode 4 of the Fig. 1 and 2 therefore has an in Fig. 1 and 2 not shown central through hole through which a coolant flows.
  • a device according to the invention can be produced inexpensively and compactly due to its relatively simple and uncomplicated construction. Due to the compact construction with a relatively small volume of vacuum evacuated space of a device according to the invention is evacuated in a further embodiment only in the manufacturing process, a working gas in the evacuated space introduced and the evacuated space then vacuum sealed.
  • a device according to the invention may also have first means for evacuating the evacuable space and second means for supplying a working gas into the evacuable space.
  • first means for evacuating the evacuable space and second means for supplying a working gas into the evacuable space.
  • the evacuation of the evacuable space and the supply of the working gas can take place continuously or with a time interruption.
