Definitions

  • the invention relates to an electrostatic precipitator, in particular for an exhaust pipe of an exhaust gas purification system, according to the preamble of claim 1. Further, the invention relates to a heating system for generating heat by burning an energy source with an electrostatic precipitator according to claim 13.
  • emission control systems Due to emissions from heating systems and global efforts to reduce such emissions - see, for example, the Kyoto Protocol or legislation for small wood firing systems - heating systems use appropriate emission control systems. These are in particular to filter out the harmful substances and particles from exhaust gases, so that the remaining, purified exhaust gas can be safely released to the environment. In particular, such emission control systems are used in biomass heating systems, where in addition to otherwise economic and environmental benefits especially the relatively high emissions of particulate matter can pose a problem.
  • An emission control system which is used for biomass heating systems to reduce particulate matter emission.
  • the device described therein can be installed in a flue gas channel and for this purpose has a lid which can be placed gas-tight on an associated opening on a flue gas channel.
  • a so-called spray electrode for example in the form of a tensioned rod, is held over an insulating holder.
  • a high-voltage transformer with rectifier function allows the construction of a high DC voltage between the wire and the lid, which is electrically connected to the exhaust pipe, so that it acts as a so-called collector electrode.
  • Such an electrostatic filter with a spray electrode and a collector electrode is also known as an electrostatic precipitator.
  • This is used for exhaust gas purification in an exhaust pipe of a heating system.
  • the spray electrode extends substantially along the exhaust gas flow direction and approximately centrally through the exhaust pipe, which is why it also serves as the center electrode referred to as. Together with an acting as a collector electrode, the surrounding outer surface of the exhaust pipe, it forms a capacitor which is also referred to as a cylindrical capacitor in a cylindrical tube-shaped design of the exhaust pipe.
  • the spray or center electrode generally has a circular cross section, wherein the diameter of the cross section or the radius of curvature is generally formed relatively small (for example, less than 0.4 mm).
  • an electric field extending transversely to the direction of flow is clamped between the center electrode and the exhaust gas pipe.
  • a high voltage is applied to the center electrode, for example in the range of 15 kV.
  • corona discharge is formed, through which the particles flowing with the exhaust gas through the electric field are charged unipolarly. Due to this charge, most of the particles migrate through the electrostatic Coulomb forces to the inner wall of the exhaust pipe, which serves as a collector electrode.
  • the particles are electrostatically charged by the corona discharge that forms along the surface of the spray electrode. This is done at the molecular level by the following process: If the electrode is e.g. relative to the exhaust pipe to negative high voltage, so a large number of gas molecules is negatively charged. They move in the electric field applied by the electrode and the exhaust pipe in the direction of the exhaust pipe. If these meet on their way through the exhaust pipe to electrically neutral particles, they stick to these and charge the previously neutral particles also negative. The charged particles flow driven by electrostatic deflection forces to the inner wall of the exhaust pipe. Here the particles stick, lose their charge and are safely removed from the exhaust stream. This is the core process of an electrostatic precipitator and, depending on the geometry, height of the corona current, electrode shape, etc., leads to deposition rates of up to more than 90%. This core process can be disturbed by the following effects:
  • Burning produces bipolar charged particles.
  • the distribution is symmetrical, ie, there are the same number of positive and negative charged particles.
  • the number of charged particles is reduced by approx. 10% per second due to coagulation, there are still more than 10% charged particles at the electrostatic precipitator (corresponding to about one to two seconds of particle flying time from the place of combustion).
  • Get the loaded ones Particles now in the vicinity of the lying on negative high voltage electrode of the charger (unit of exhaust pipe and electrode) the negative particles will flow away from the electrode towards the exhaust pipe inside.
  • the positive particles on the other hand, flow towards the electrode.
  • a disadvantage of the electrostatic precipitators according to the prior art is that it comes after a longer period of operation to a continuous degradation (reduction) of the corona current at a constant high voltage. As a result, the charging efficiency of the electrode decreases, which in turn reduces the separation efficiency of the entire system. Remedy is provided by the maintenance and cleaning of the separator, which must be carried out by qualified personnel because of the high-voltage components that are present.
  • the invention has for its object to provide an electrostatic precipitator, which overcomes this disadvantage and in particular provides improved operation and extended cleaning intervals. Further, the invention has for its object to provide a heating system with a separator according to the invention, which guarantees reliable exhaust gas purification.
  • the electrostatic precipitator according to the invention is characterized in that in the electrostatic precipitator, in particular for an exhaust pipe of an exhaust gas purification system, with a channel wall and a flow channel through which a particle-containing exhaust gas flows in a flow direction and an electrode extending in the flow channel substantially in the flow direction , for forming an electric field between the electrode and the channel wall, is provided that further comprises an electrode holding device and at least one Pumbleabweisesch are included, and that the spray electrode is at least partially formed integrally with the electrode holding device.
  • the at least one particle-repelling agent prevents or reduces the fact that particles of the exhaust gas are deposited on the electrode, in particular permanently deposited.
  • the particle repelling agent can effectively reduce the deposition of particulates on other components of the electrostatic precipitator.
  • the electrode holding device is expediently arranged approximately centrally in the exhaust gas line and extending in a substantially rod-shaped manner along the exhaust gas flow direction. To fix the electrode holding device on the separator or on the exhaust pipe, it can be made in one piece with the high-voltage supply or separated from it on a separate suspension.
  • a heatable particle repelling agent protects the electrode holding device against particle adhesion.
  • the particle-repelling agent may be formed as a heating ceramic, which heats the electrode holding device. By heating the electrode holding device, a process called thermophoresis is initiated which rejects particles from the surface of the electrode holding device and thus also from the electrode surface, whereby a deposition of fine dust particles on the electrode is reduced or at least avoided.
  • the electrode holding device and the particle repelling agent may be made in one piece, i. the electrode holding device is heated directly.
  • the spray electrode is formed at least partially integrated with the heatable electrode holding device.
  • the electrode may be at least partially along a surface of the electrode holding device run, especially in close contact with the surface.
  • the electrode is adjacent, preferably adjacent and / or formed on the electrode holding device.
  • An embodiment of the electrostatic precipitator provides that the spray electrode is non-linearly extending to provide a larger active area of action in the flow channel.
  • Nonlinear in this case does not mean in a straight line, but rather curved, bent, coiled, kinked or the like.
  • a larger amount of electrode is provided in the effective deposition area.
  • the surface of the electrode is the surface of action, as it forms the responsible for the deposition of corona. Due to the enlarged surface of the electrode, the effective area is also increased. If the spray electrode is wound (wound) around a rod-shaped electrode holding device, for example, then the corona passes around the entire separation cross-section and thus reaches the entire particle-containing exhaust gas flow.
  • the electrode is at least partially formed spirally with a suitable pitch, so that adjacent areas, in particular corresponding winding areas of the electrode do not influence each other negatively.
  • the electrode has, at least in sections, current-flowable lugs, such as projections, in order to provide a larger active area of action.
  • the electrode may be formed, for example, barbed wire or with projections such as knobs.
  • Another embodiment provides a plurality of Prismabweisesch before, so for example on the electrode holding device and / or on the high voltage supply.
  • a plurality of heatable Prismabweisesch be provided, wherein the heating separately or integrated with each other can be realized.
  • the different heatable Prismabweisestoff be controlled separately.
  • the separate heating is not operated with high voltage, which may need to be transformed into low voltage.
  • a separate heating can be different Set temperatures.
  • the heatable Prismabweisestoff are preferably formed as a ceramic heater, for example as an insulator to the high voltage supply and to the electrode holding device.
  • the two Prismabweisestoff can be formed as a unit.
  • At least one particle-repelling agent can be designed as a mechanical particle-repelling agent, comprising a vibrating device, in order to at least mechanically reduce the permanent adhesion of particles to the separator or its components by vibration generated by vibration. As a result of the vibrations, adhering particles simply fall off or do not adhere at all.
  • the at least one particle-repelling agent can be arranged externally on the separator and can thus be retrofitted or removed from the separator, for example for maintenance purposes.
  • the at least one Pumbleabweisestoff may be formed integrally with the separator.
  • At least one particle-repelling agent is designed as a mechanical particle-repelling agent, comprising a fluid injection device, in order to mechanically permanently adhere particles to the precipitator or its components by injecting a fluid and the associated action of the fluid on particles to reduce.
  • the heating system according to the invention for generating heat by burning an energy source such as biomass is characterized in that it is provided with a particulate matter emitting heating system such as a biomass heating system for burning the energy carrier, wherein particle-containing exhaust gases, and an inventive electrostatic precipitator is provided.
  • An avoidance or reduction of fine dust deposits on the electrode is realized. Due to the non-linear design of the electrode, which is also called center or spray electrode, possibly also with projections, the active surface or the effective area of the electrode is increased.
  • the system ceramic hot spray spiral whose fine dust contamination can be successfully prevented by thermophoresis. Will a surface in the particle laden exhaust stream a firewood plant or an internal combustion engine or the like heated to about 100 K above the ambient gas temperature, the temperature gradient to the environment, the deposition of especially small, clearly sub-micron particles ( ⁇ 200 nm) reliably prevented.
  • the charging efficiency of the spiral electrode is not reduced in the locally low-particle volume, since the mean free path of the ions, which charge the fine dust particles, is increased by the increase in temperature.
  • the heating ceramic spray spiral system By heating the heating ceramic spray spiral system to over 100 ° C, the condensation of a water film on the spiral is prevented. The water film would make it difficult to form a high enough corona stream.
  • the system can be used immediately at the start of the biomass heating system burner, where experience has shown that most of the particles are emitted.
  • the system can also be used downstream of condensing heat exchangers (calorific value utilization). Here the use of unheated electrodes is hardly possible.
  • the system can also be mechanically freed of particulate matter by a vibrating device as shown in the figure. Also for their activation, the shift of the current / voltage characteristic of the high voltage supply can be used.
  • Electrostatic precipitators are in the exhaust system a minimum flow resistance, which increases only very slowly with increasing load. They have a large absorption capacity for separated fine dust. At slow flow velocities and sufficiently long separation distances, they have a deposition efficiency of 80 to 90% for submicron particles. For the reasons mentioned above, they are therefore a promising option for the purification of waste wood in firewood plants, other biomass heating systems or oil burners.
  • the maintenance of the high voltage of the center electrode is a technical difficulty in the design of the electrostatic precipitator.
  • the spiral electrode of particulate matter contamination can be kept free or cleaned:
  • thermophoresis the keeping of the spray electrode is achieved by merely heating the same. This option is characterized by minimal energy consumption (5 to 10 W electrical heating power), long service lives and quietness (no moving parts). If, after an extremely long service life, contamination of the ceramic insulation nevertheless occurs, it can be burnt free by a second, higher power level.
  • the fraction of the accumulated particulate matter that can not be dissolved by burnout can be removed from the spiral electrode by the application of mechanical energy.
  • the mechanical cleaning by a vibrator is carried out in the following manner.
  • an eccentric is mounted in the immediate vicinity of the high-voltage passage or supply of the spray electrode so that it can set the spray electrode into vibration.
  • the eccentric is activated (rotated) upon reaching a certain degree of contamination for a defined period of time, so that the charger is set in vibration and the inside adhering dust drops.
  • the degree of contamination of the spray electrode can be determined in various ways (eg optically, electrically, etc.).
  • a preferred example for an implementation of an automated cleaning is given: By detecting the current-voltage characteristic of the spray electrode, it is possible to determine their degree of contamination. This effect can be used to control the vibrator. If a previously defined degree of contamination is reached, the control activates the vibrator. Furthermore, this effect can be used to determine the success of the filter cleaning and to control the duration of the activation. If a certain degree of contamination is reached, the control shuts off the vibrator again. If the cleaning fails, ie, the desired degree of cleaning is not achieved, the operator z. B. informed by LED display on the control unit of the electrostatic precipitator on a possible malfunction.
