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 11.
- 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.
- WO 89/12731 describes an electrostatic precipitator for purifying fossil fuel effluents with a duct wall and with a flow passage through which particulate containing exhaust flows in a flow direction. An electric field is formed between a central electrode and the grounded channel wall. An isolated high-voltage supply feeds the central electrode.
- Such electrostatic filters with a spray electrode and collector electrode are also known as electrostatic precipitators.
- 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 is also referred to as the center electrode.
- the center electrode Together with an acting as a collector electrode, the surrounding lateral surface of the exhaust pipe, it forms a capacitor, which in a cylindrical tube Design of the exhaust pipe is also referred to as a cylinder capacitor.
- 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.
- 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.

- a heatable particle-repelling agent protects the electrode holding device from 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 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 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.

- an eccentric is mounted in the immediate vicinity of Hochwoods knock- or feeding the spray electrode so that it can put 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 of an implementation of an automated cleaning is given: By detecting the current-voltage characteristic of the discharge electrode, it is possible to determine the degree of soiling. 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.
