Definitions
- the invention relates to an electrostatic dust separator according to the preamble of claim 1 .
- Another prior art dust separator is known from CN 205903986 U, for example.
- this dust separator also comprises a scraper device which is pivotably suspended within the housing, with associated drive elements for this scraper device, namely in the form of a pinion and a toothed rack cooperating therewith, being arranged directly inside the housing.
- the resulting disadvantages are the same as those already explained above for DE 1900526A.
- the object of the invention is to optimize the drive technology for an associated scraper device for an electrostatic dust separator.
- An electrostatic dust separator is intended for a horizontal gas passage, and for this purpose comprises a cylindrical housing which is arranged horizontally and can be flowed through by flue gas along its length.
- the housing has openings on each of its two end faces for this purpose, through which the smoke gas can flow into and out of the housing.
- At least one precipitation field with precipitation electrodes and discharge electrodes arranged between them is provided within the housing.
- the collecting electrodes can, in particular, be designed in the form of plates and each be arranged vertically within the housing.
- At least one dust discharge opening is formed in a bottom area of the cylindrical housing.
- the dust separator according to the invention comprises at least one scraping device, which is arranged in the lower half-cylinder of the housing and adjacent to the inner peripheral surface of the housing, the scraping device being rotatably mounted about a pivot axis running in the longitudinal direction of the housing.
- the dust separator according to the invention also includes drive means, by means of which the scraper device can be pivoted back and forth about the pivot axis, namely in such a way that when the scraper device is pivoted about the pivot axis, dust particles that have settled in the bottom area of the housing are removed from the Scratch device are solved and thereby successively in the dust discharge can be introduced.
- the drive means are arranged outside of the housing and are operatively connected to the scratching device via at least one associated connecting element.
- the drive means are designed in such a way that a linear actuating force that can be transmitted to the scratching device can be generated, with the direction of this linear actuating force running tangentially to the circumference of the housing.
- a separate scraper device is provided for each of its electrical precipitation fields, which is rotatably mounted about the pivot axis running in the longitudinal direction of the housing and is attached by means of associated struts to a pivot bearing, through which this pivot axis runs.
- the lower edge of the scratching device is designed in such a way that it is arranged hanging on the pivot bearing in such a way that it is adapted to the round bottom area of the housing and is only at a small distance therefrom.
- the present invention is based on the essential finding that the drive means, with which an associated scratching device can be driven to move back and forth about the pivot axis within the housing, are exposed to a lower thermal load because these drive means are arranged outside the housing.
- Such an arrangement of the drive means can be achieved with the aid of at least one associated connecting element which is guided through an opening in the housing and in this respect ensures an operative connection between the drive means arranged outside the housing and the scratching device located inside the housing.
- the above-described attachment of the drive means outside the housing of the dust separator can be implemented in a simple manner by providing a fastening plate or the like on an outer peripheral surface of the housing, to which the drive means are attached.
- a further advantage of the present invention is that an independent or separate drive can be implemented in a simple manner for a plurality of scratching devices which are assigned to the individual electrical precipitation fields within the housing and thus also for these scratching devices, if necessary different drive parameters (e.g. amplitude, frequency) can be set, with which these scratching devices are moved back and forth around the pivot axis according to a “rocking movement”.
- different drive parameters e.g. amplitude, frequency
- a scratching device of a respective precipitation field - in a plane orthogonal to the longitudinal extent of the housing - extend along the bottom portion of the housing by an angle having a value between 110° and 130°.
- This angle can preferably assume a value of 120°. This ensures that dust particles that have settled in the bottom area of the housing in its lower half-cylinder are caught over a large area or in a wide area by the scratching device during its “rocking movement” around the pivot axis.
- the drive means with which in the dust separator according to the invention a scraping device of a respective electrical precipitation field is set in a "rocking motion" about the pivot axis, can be designed as: linearly actuable actuating cylinder, for example in the form of a pneumatic cylinder or a hydraulic cylinder, or electric linear drive, or electric spindle drive, or
- Cable winch or the like preferably motor-driven, namely in the event that a connecting element for realizing an operative connection with the scratching device is designed in the form of a cable.
- a mechanically simple and at the same time robust design of a connecting element, through which the drive means are operatively connected to a scratching device can be implemented, for example, by a coupling rod.
- a coupling rod is used to exert a linear actuating force, ie alternating tensile and compressive forces tangential to the housing circumference, on a scratching device, thereby achieving a desired “rocking movement” of the scratching device about the pivot axis running in the longitudinal direction of the housing.
- a linear actuating force ie alternating tensile and compressive forces tangential to the housing circumference
- the opposite end of the coupling rod, which faces the drive means is also connected in an articulated manner to these drive means.
- these articulated connections provided for the coupling rod effectively avoid possible tensions, inclined positions or the like, which could otherwise be generated for the coupling rod when the drive means is actuated and the linear actuating force generated thereby.
- the coupling rod is designed in multiple parts and these parts of the coupling rod are connected to one another in a pivoted manner. This also ensures that when the drive means is actuated, possible stresses on the coupling rod do not occur or cannot arise in the first place.
- a connecting element is designed in the form of a coupling rod
- the drive means are movably connected to the fastening plate provided on an outside of the housing.
- This mobility can be achieved by a rotary joint and/or by rubber elements that are designed to be flexible and elastic.
- a movable mounting of the drive means on the fastening plate has the advantage that when the drive means is actuated, it is possible to compensate for possible tension or the like for the coupling rod.
- a connecting element if it is in the form of a coupling rod, can also be part of a joint mechanism by which the scratching device is operatively connected to the drive means.
- a joint mechanism can expediently comprise a pivoted lever and/or a toggle lever, for example in the form of those mentioned connecting rod.
- the advantage is achieved by such a joint mechanism that the required stroke or travel of the drive means can be reduced.
- the drive means are designed as hydraulic or pneumatic cylinders, according to an advantageous development of the invention, it can be provided that with a sufficiently long piston rod of such an actuating cylinder, such a piston rod simultaneously fulfills the function of a connecting element with which an operative connection with an associated scratching device is realized .
- a piston rod with a sufficiently large length, is then connected with its free end directly to an edge region of an associated scratching device, preferably in an articulated manner.
- the connecting element can also be designed in the form of a pulling cable, with which a pulling force is then exerted on the scratching device from one side.
- drive means for example in the form of a motor-driven cable winch or the like, are provided on both sides of the housing, viewed in the direction of the longitudinal extent of the housing, i.e. on its longitudinal sides and each associated with a scratch device.
- a scratching device is controlled from both sides by means of pull cables in order to achieve a desired “rocking movement” around the pivot axis for the scratching device.

Two of these carriers T are each arranged adjacent to the end faces of the housing 12 (i.e. adjacent to the inlet area 30 or the outlet area 40), with the remaining three carriers each separating the total of four electrical precipitation fields 13 from one another.
- a pivot bearing 19 is preferably attached in a central area thereof.
- these rotary bearings 19 in the individual carriers T it goes without saying that these are preferably aligned exactly with one another and thus jointly define a pivot axis Ai (cf. FIG. 3). This pivot axis Ai runs parallel to the longitudinal axis L of the housing 12.
- Two struts 18 are attached to a side strut S of the scratching device 17, preferably to the two end sections thereof, which are attached to the pivot bearing 19 of an associated carrier T with their opposite ends.

- a torque about the pivot axis Ai is transmitted from the drive means 20 to an associated scratching device 17, which is thus set in a rocking motion about the pivot axis Ai.
- a connecting element 22, with which an operative connection between the drive means 20 and a scratching device 17 is realized, can be designed in the form of a coupling rod.
- an opening 24 is formed in the wall of the housing 12, through which the coupling rod 22 (or also a piston rod of a hydraulic or pneumatic cylinder) extends.
