Description of the invention: [Technical field to which the invention pertains] „ The invention relates to the citation of the first item of the patent application scope----------------------------------------------------------------------------------------------------------------------------- a filter, in the form of an electrostatic dust separator, in the case of such an electric filter, a gas stream carrying particles or dust is placed between parallel deposition plates in a substantially cylindrical housing portion Guided in the segment. There is a longitudinally extending passage between the parallel-aligned deposition plates (G job). These channels are provided with "squeezing electrodes" (S_helektrod) in the frame. The spray electrode in the frame is designed in a metal form and subjected to relevant mechanical stresses when the temperature changes, except that the electrode wire may be torn off (this situation may cause a short circuit), and additionally due to mechanical stress in the electrode frame The stretching is caused in such a way that the distance between the high-voltage electrode frame and the adjacent deposition plate is improperly changed, and in the case where the electrode wire is broken, in the actual operation of the electric filter of this configuration, based on the maintenance cost Rational by. Often only the broken electrode wire is removed, so the electric filter - until the complete repair of the road - the efficiency is reduced. SUMMARY OF THE INVENTION An object of the present invention is to provide an electric filter which can be easily manufactured' while having high operational safety and high efficiency. For this purpose, the above-described type of electric filter is achieved by the present invention in accordance with the feature points of the first item of the patent application. By fixing the electrode in a fixed position on a carrying beam of the electrode implant in the manner claimed by the patent application 201102168, it is not necessary to sandwich the electrode, even if the temperature fluctuates greatly and the mechanical properties of the electrode frame are When the stretching is also correspondingly large, it is also possible to avoid electrode damage or stretching of the electrode frame. Here, a preferred detail of the invention is designed (but not absolutely necessary). The φ electrode protrudes downwards and upwards from the carrying beam, so that the housing configuration with a nearly circular cross section can be fitted in a simple manner. The main field of application is to remove dust from the converter gas. Since the operation mode of the converter is discontinuous, the gas purifying device is alternately flown by the flammable converter gas carrying dust and the ambient gas containing only a small amount of dust. In the blow phase of the converter, the combustible converter gas produced is collected in a gas container after the dust is separated. A switching station installed behind the filter allows the unburnable waste air to be diverted to the atmosphere via a cigarette. If the converter gas is mixed with the oxygen-containing waste air of the Blaspause, an explosive gas mixture is produced, which can ignite in the electric filter and cause a gas explosion (Verpuffungp gas explosion can cause dust particles to rebound In addition, it affects the separation efficiency of the electric filter. In addition, they interfere with the operation of the converter because they cause interruption of the blowing process. Therefore, the electric filter of the present invention having all of these features is particularly suitable for this application field, and The circular housing shape is particularly advantageous for flow through while providing good mechanical strength throughout the electrical filter. In a particularly preferred embodiment of the invention, the electrode is again self-supported along at least a vertical direction a (selbsttragend '英: self_supp〇rting' and form-formed form, so the necessity of electrode clamping 4 201102168 can be eliminated in a simple way, in a better way (not 纟帛n,,#, , not absolutely necessary) In the detailed design, for example, they can be designed as conventional s spray electrodes, or electrodes with a quadrangular cross-face, or with a cross-shaped cross The electrode of the surface is generally advantageous in that the electrode is fixed in a fixed position only on a carrying beam of the electrode frame. This prevents the electrode from being excessively vibrated or mechanically stretched without The electrode is fixed in a certain position in a plurality of positions in its length range. 丕丨^ 疋 Otherwise, each fixing causes mechanical stress when the temperature changes greatly. In a generally preferred implementation, it is necessary to make full use of it. Between the constructions*, at least some of the electrode frames have a mutually independent dimension relative to their position in the nearly circular cross section of the housing. In order to utilize the width of the housing in a simple manner, the carrying Candle ice Λ 豕 榡 榡 〇 〇 〇 〇 具有 具有 具有 具有 具有 具有 具有 具有 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少 至少The distance between the upper end and the lower end. The generally advantageous way is to design the carrying beam into the electrode frame of the crossbar (Kl〇Pf_ge), so the electrode can be blown in a simple manner (AnSChlagen) for dust removal. according to The support method of the invention is generally sufficient as long as the hammer rod is struck by one side. In a simple and effective structure of the electric filter of the present invention, the carrying beam of the plurality of electrode frames is at least two horizontal carriers, in particular A transverse carrier arranged along the longitudinal direction extends between and is held by the transverse carrier. In a preferred further feature t, the transverse carrier is fixed in the housing via an electrical insulator. Each of the reinforcing rings, which are suspended from the casing, has a configuration of an electric cross-over device having a cross-section of a pattern, and in the case of 201102168, each of the two reinforcing rings of the casing is provided. a field of a deposition plate and an electrode frame. In a generally advantageous embodiment, at least two electrode frames are connected to each other in a transverse direction via a freely floating fixed cross frame, in particular in the longitudinal direction before a field of the deposition plate and / or after. These fixed cross members can reduce the relative vibration of the individual electrode frames by a simple means without significantly increasing the weight or construction cost. Other features and advantages of the present invention are found in the embodiments described below and in the scope of the Shenqing patent scope. [Embodiment] A filter of the present invention comprises a casing (5 not shown), a cylindrical section of the casing having a substantially constant and substantially circular cross-sectional view, wherein the longitudinal direction of the electrical transition Extending in the direction of the axis of the cylinder, gas carrying particles or dust also flows through the electric filter in this direction. In the cylindrical casing section, two or a plurality of reinforcing rings (not shown) are provided, which are spaced apart from each other in the longitudinal direction L. The reinforcing ring is used to support the casing on the one hand and the other on the other hand. The field of the deposition plate is kept. Furthermore, a plurality of electrode frames (1) are fixed on the reinforcing ring. They are fixed parallel to each other on the transverse carrier (2). The transverse carrier extends in the lateral direction through the casing and is fixed to the transverse carrier (2). Each end region of a carrying beam (2) of each electrode frame is achieved. Here, the end regions of the carrying beam (2) rest on one of the two transverse carriers (2) and are held there by other means. An electrode frame (1), in addition to the carrying beam (3) (which extends along the longitudinal direction l of the casing), also includes a vertical weir (4) extending along the vertical or height direction to 6 201102168 and several other reinforcing beams. (5) The reinforcing beam extends longitudinally parallel to the carrying beam (3) between the vertical beams (4). Here, the reinforcing beam (5), the vertical beam (4) and the carrying beam (3) are fixed to each other in a certain position, thereby forming a wire-type frame (see Fig. 丨). The wire-shaped electrode frame (1) is fixed to the transverse carrier (2) via the end region of the carrying beam (3), and the transverse carrier itself is suspended in the reinforcing garment of the housing via the insulator (7) (not shown) Vertical lock on the upper part. The entire electrode frame (!) is applied with a voltage during operation, in which adjacent deposition plates (not shown) are grounded. The electrode frame shown in Fig. 1 is for explanation, so the electrode is not mounted. To mount the electrode 'the corresponding protrusion (3a) on the carrying beam (3). As shown in the cross-sectional view of Fig. 2, the electrodes (8) [which are fixed in a fixed position on the projection (3a) of the carrying beam (3)] vertically protrude upward and downward from the carrying beam (3). The extension 0 electrode (8) is guided on the reinforcing beam (5), for example by means of a hole or a longitudinal slot provided in the reinforcing element (7). It is not fixed to the reinforcing beam (5) in a fixed position here. In the illustrated embodiment, the electrode (8) protrudes in the height direction beyond the end of the electrode frame (1), wherein the space through which the cylindrical body passes is particularly well utilized. Fig. 2 is a top end side view of the assembly of the transverse carrier (2) and the electrode frame (1), the assembly being suspended in a casing (not shown) of the electric filter. Thus, the free-floating "solid money rack" (9) can be seen, which each connect the electrode frames (1) to each other to prevent the electrode frames from vibrating relative to each other when the electric transition device is operated. Electrical over-expansion, a deposition plate extending between the electrode frames (1), is not shown. There is a free path between the deposition plates (which are aligned parallel to each other), and the 201102168 pole frame (i) is placed in the path where the electrode (8) is designed as a "tube spray electrode". They have a particularly large cross-section®, which maintains the vertical orientation of the circle with its own support (selbsttragend 'self: self_supp〇rting) and a stable shape. The electrodes do not have to be clipped along their length, and the electrodes (8) extending downward from the carrying beam (3) are not required to be provided with heavy snakes, since these electrodes are designed in the form of a shape 敎 on the one hand and Guided on the beam. In order to knock off the particles deposited on the electrode frame (1) and the electrode (8), the respective carrying beams (3) are struck by a conventional technique using hammering waves and hammering. Here, due to such a structure, the carrying beam (3) is sufficient as long as it is hit by the side. But it can also be used for both sides. As shown in the correct scale diagram of Fig. 2, the beam (7) is disposed at a large distance from the upper end of the casing (not shown) in the height direction η such that the distance is at least equivalent to at least the entire diameter of the substantially circular casing. One-twentieth. For example, the lateral carrier (7) is sufficiently long in the lateral direction Q to accommodate a plurality of mutually parallel electrode frames (1)' and to optimize the width of the casing. As can be seen directly from Fig. 2, the electrode frames (1) each have a different height depending on the arrangement in the lateral direction Q, wherein the electrode frames have a total of three different structural widths, and the lengths of the electrodes (8) used are each branched. Depending on the position of the direction, it is designed to be thinner than the segment of the frame height '俾 optimally utilizing the structural shape of the electric filter to separate the particles.
