Code 110 The invention pertains to the technique of gas cleaning and dust collecting in can be used to collect tea particles and dust from industrial gases in electrostatic precipitators. A device for fastening and tensioning elements of frame-type corona-conducting electrodes is known, which contains elements of discharge electrodes attached to the frames of discharge electrodes made of tubes and on the clamp screw tl 3. The disadvantages of the known device are the laboriousness of manufacturing the elements, the unreliability of the connection of the elements with the frame, because in the places of their connection there is an effect of electric power, as well as the difficulty of adjustment during tension of elements. This goal is achieved by the fact that both ends of the elements are made in the form of semi-cylinders, covering pipes, and welded to the last torques of the electric amps, and the pressure screw is installed with an emphasis in the middle of one of the semi-cylinders. FIG. 1 shows the frame-type corona electrode} in FIG. 2, section A-A in FIG. Ij in FIG. 3 is a view B in FIG. 2, The device consists of a pressure screw 1 screwed into a frame 2 made of pipes, and both ends of the e-mails of the enclosing electrodes 3 are made in the form of semi-cylinders covering pipes 2 and welded to the last along the ends of the elements, the middle of one of the semi-cylinders ,. The device works as follows. The elements 3 of the corona electrodes are tightened with a pressure screw 1, which is screwed into the pipe 2, pressing and pulling the element. The technical advantages of the invention are to increase the reliability of the connection of the elements of the discharge electrodes with the frame and to reduce the labor intensity of their manufacture. In the device, both ends of the element are fed to the frame by welding, eliminating electrical erosion at the joints of the element and the frame. The absence of electro-erosion in the places of replenishing the elements to the frame significantly increases the reliability of the device operation.
