    专利说明:

    The invention relates to a heating boiler having an electrostatic precipitator provided in an exhaust gas flow passage and comprising a discharge electrode disposed in the exhaust flow passage and a collector electrode formed by the passage walls.
    For cleaning the exhaust gases of a boiler, it is known (DE 20 2010 016 019 U) to provide an electrostatic precipitator within a boiler in the exhaust gas flow channel. This electrostatic precipitator is formed by a discharge electrode disposed in the exhaust gas discharge electrode and a collector electrode formed by the channel walls. The disadvantage of this, however, that according to the arrangement in the boiler cleaning of the collector electrode formed channel walls and within the exhaust gas flow channel extending spray difficult or only with great effort is possible. In addition, in such an arrangement of the two electrodes of the electrostatic precipitator is generally expected with a relatively low degree of deposition.
    The invention is therefore based on the object, a boiler of the type described above in such a way that the degree of separation of the electrostatic precipitator can be improved.
    The invention achieves the stated object by providing flow plates distributed within the exhaust gas flow channel over the channel length, which flow inclined to the channel axis over the channel cross section and have the spray electrode receiving flow openings for the exhaust gases.
    As a result of these measures, the flow plates distributed over the channel length cause turbulence in the exhaust gas flow, increase the relative residence time of the exhaust gases in the electrostatic precipitator and thus also improve the degree of separation. Moreover, when the flow sheets are arranged to contact the channel walls, the flow sheets themselves form a collector electrode, thereby increasing the effective electrode area for the electrostatic precipitator.
    In order to enable the cleaning of the electrostatic precipitator, the loose against the exhaust gas flow channel flow plates can be applied to the channel walls Abstreifkanten and connected to a running in the direction of the channel axis actuator. On the one hand, the scraping edges abutting the channel walls ensure electrical contact between the flow plates and the channel walls, and on the other hand, the channel walls are cleaned by relative movement of the scraping edges with respect to the channel walls when the actuating drive is actuated. Particularly advantageous conditions for the cleaning of the channel walls arise when the actuator comprises an actuating linkage, which is connected to the flow plates in the region of the opposite, with respect to the exhaust flow upper and lower scraping edges and engages at least in the region of a scraping edge with play on the flow plates. Accordingly, it comes with an actuation of the actuating linkage to a tilting of the flow plates and attached thereto Abstreifkanten, so that the latter are pressed against the channel walls. This effect can be enhanced by the fact that the actuating linkage of the actuating drive acts at least in the region of a scraping edge both with play in the direction of the actuating linkage and with play transversely to the actuating linkage and to the channel walls on the flow plates.
    As a prerequisite that together with the collector electrodes formed by the channel walls and the spray electrode can be cleaned, the spray electrode can be attached to a, outside the exhaust gas flow channel and attached to the actuator connected electrode holder.
    In this connection, the part of the spray electrode adjoining the electrode holder may be surrounded by a dust-repellent insulator and a cleaning device may be provided for the insulator, which is provided in the region of the actuating travel of the insulator caused by the actuating drive. For example, this cleaning device may be arranged in the region of the passage of the spray electrode through the frontal wall portion of the exhaust gas flow channel. Upon actuation of the actuating drive of the actuating linkage, therefore, not only the collector electrode formed by the channel walls will be cleaned via the scraping edges of the flow plates, but also the part of the insulator of the spray electrode which slides through the cleaning device.
    For example, for this purpose, the cleaning device for the insulator from one or more fins may be formed, which surround the insulator in the region of its implementation by a channel wall.
    In order to clean off the spray electrode extending in the exhaust gas flow channel in addition to the insulator of the spray electrode, a mechanical vibration unit may be provided for the spray electrode. This vibrating unit can comprise, for example, an actuating arm provided in the region of the cleaning device for the insulator and an, for example, electromagnetic control for this actuating arm. The control for the actuating arm is designed so that the actuating arm abuts with its one end portion of the spray electrode, which can be cleaned by this shaking.
    In order to further increase the degree of separation of an electrostatic precipitator, a spray electrode, as may be used, for example, in a heating boiler according to the invention, be formed by an electrically conductive, wound with a wire round or threaded rod, which at one end of an insulator is surrounded and wherein the wire in the region of the insulator with the round or threaded rod is electrically connected and wound around the non-insulating part of the lower round or threaded rod at a distance. The fact that the wound around the round or threaded rod wire is not directly applied to this, but surrounds it due to its own mechanical stability at a distance, the effective surface of the spray is increased and thus improves the Abreinigungsleistung.
    Particularly advantageous Abreinigungsbedingungen arise in this context, when the wound around the round or threaded rod wire is a square wire, because it comes in the region of the edges of the square wire to increase the electric field strength. This effect also results when using a threaded rod as the basic element of the spray electrode, because the edges of the thread of the rod also lead to a maximization of the electric field strength in their area.
    In the drawing, the subject invention is shown, for example. Show it
    1 shows a section of a boiler according to the invention in a schematic representation,
    2 shows the passage region of the spray electrode through the end-side channel wall of the exhaust gas flow channel on a larger scale and FIG. 3 shows a section along the line III-III of FIG. 1, also on a larger scale.
    A boiler according to the invention comprises a Feuerungsretorte 1, an adjoining combustion zone 2 and a burn-out zone 3, which opens into a heat exchanger 4 and an exhaust gas flow channel 5. The exhaust gas flow channel 5 is formed by a leading to a flue gas fan 6 riser. Within the exhaust gas flow passage 5, there is provided an electrostatic precipitator comprising a discharge electrode 7 arranged in the exhaust gas flow passage 5 and a collector electrode formed by the passage walls 8 of the exhaust flow passage 5. Within the exhaust gas flow channel 5 are distributed over the channel length in the longitudinal direction flow plates 9 are provided, which are inclined to the longitudinal axis of the exhaust gas flow channel 5, extending over the cross section of the exhaust gas flow channel 5 and flow openings 10 for receiving the spray electrode 7. The flow plates 9 are loose against the exhaust gas flow channel 5 and form abutting the channel walls 8 stripping edges 11, 12. For cleaning the channel walls 8, the flow plates 9 are connected to a running in the direction of the channel axis and an actuating linkage 13 having actuator. By actuation of the actuating drive and thus of the actuating linkage 12, therefore, the flow plates 9 can be moved with the scraping edges 11,12 relative to the channel walls 8 of the exhaust gas flow channel 5, so that with the help of the scraping edges 11, the channel walls 8 can be cleaned. In order to press the scraping edges 11 of the flow plates 9 to the channel walls 8, so that the actuating linkage 13 may be connected to the flow plates 9 in the region of the opposite, with respect to the exhaust gas flow upper scraping edges 12 and lower scraping edges 11, wherein the actuating linkage 13 at least in the region of a scraping edge 11, 12, for example, in the lower region of the scraping edge 11 with play on the flow plates 9 attacks. According to this measure, the flow plates 9 are tilted transversely to the longitudinal axis of the exhaust gas flow channel 5 upon actuation of the actuating drive, so that the scraping edges 11 and 12 are pressed against the channel walls 8 of the exhaust gas flow channel 5.
    The spray electrode 7 extending within the flow openings 10 for the exhaust gases may be fastened to an electrode holder 14 arranged outside the exhaust gas flow channel 5 and connected to the actuating linkage 13 of the adjustment drive. The adjoining the electrode holder 14 part of the spray electrode 7 may be surrounded by a dust-repellent insulator 15, wherein the insulator 15 with its end facing away from the spray electrode 7 forms a connection for a high-voltage connection 16. For the insulator 15, a cleaning device 19 may be provided in the region of the adjustment path of the insulator 15, preferably in a passage opening 18 provided in the end face 17 of the exhaust gas flow channel 5, in the region of the adjustment path. This cleaning device 19 may advantageously be formed from one or more lamellae 20, which surround the insulator 15 in the region of the passage opening 18 of the end face 17 of the exhaust gas flow channel 5. The cleaning device 19 may be provided with a shaker unit 21, which is constructed from an electromagnetic drive 22 and from an actuating arm 23. The actuating arm 23 strikes with its one end portion of the spray electrode 7, which can be cleaned by this shaking.
    In order to increase the cleaning performance of the electrostatic precipitator according to the invention, the spray electrode 7 may be formed by an electrically conductive, wound with a wire 24 round or threaded rod. The round or threaded rod 24 spirally and at a distance surrounding wire 25 is conductively connected in the region of the insulator 15 with the round or threaded rod 24 via a connecting sleeve 26. In addition, one or more spacers 27 may be provided for the wire 25 on the threaded rod. To increase the degree of separation of the electrostatic precipitator, the wire 25 may be formed as a square wire, wherein the edges of the square wire cause a local maximization of the electric field strength.
