SU679167A3 - Device for leading- in bus-bar through the closure of electric filter used at phosphorus production - Google Patents

Description

The torus 6 is mounted above the cover 2 of the 3JTeKt filter 3. The insulator 6 can be made cylindrical (Fig. 1 and 2) or in the form of a washer (Fig. 3).

On the lid 2 of the electrostatic precipitator 3, a submersible tank 7 is located concentrically with the busbar 1, which serves to prevent the release of combustible gas consisting of phosphorus and carbon monoxide into the atmosphere with pressure fluctuations caused by the flow of the phosphorus furnace. Above the submersible tank 7 in the insulator 6 there is a cavity 8 filled with gas, which counteracts the excessive pressure that constantly exists in the electrostatic precipitator 3. This cavity is limited below the insulating sleeve 9 installed on the busbar 1, surrounded by Washer 10 fixed on the immersion bell in such a way that there is a nanor - 20 gap 11 in the annular form between the insulating sleeve and the rigid washer .The walls of the cavity 8 are insulator 6, if it is made of axle. made in the form of a washer, it is installed on the conductive housing 12, thus 25 that the insulator with the conductive housing forms a cavity 8. The cavity 8 through the supply of the tube 13 is filled with an inert gas opposing the excessive pressure in the electrostatic precipitator 3. Inert gas t even in the direction of the arrow A through the existing between the insulating sleeve 9 and the washer W a gap of annular shape inside the electrostatic precipitator 3 and further with other beds and gases is removed from the electrostatic precipitator 3. Due to the constant flow of an inert gas through the annular gap of the annular form, inside the electrostatic precipitator 3 the possibility of contaminated gases or vapors from the inside of the filter in the cavity bounded by the insulator is excluded, as a result of which contamination of the insulator 6 is practically excluded and, therefore, it is electrically firm not be reduced.

The insulator 6, the insulating sleeve 9 and the washer 10 are made of polytetrafluoroethylene. 45 The inlet pipe 5 passes from the inside of the electrostatic precipitator 3 through its lid 2 approximately i to the upper third of the submersible tank 7. And the tank 14 of the submersible tank 7 is fixed to the immersion bell 15, which lowers §0 to approximately the lower quarter of the tank. The submersible tank 7 is half filled with water and the flow-through tube 16 is located approximately in the middle of the height of the tank 16. The tank 7 is filled with cold water through the feed 17, and through 55 the water pipe 18 is emptied. In order to avoid evaporation or small particles of water on the insulator 6, oil floats on the surface of the water inside the immersion bell 15.

film 19. D / g - removal of gases and vapors, which occur when the pressure inside the filter is accidentally spilled or after the accidental breakdown of the submersible tank 7, in the upper part of the tank there is a pipe 20 leading to the chimney.

The crash of the corona electrodes system from those that settle on it during the operation of the sticking filter, is performed by constantly shaking it. For this, a metal bellows 21 is provided, reinforced with the lower part on the insulator 6, and the upper part on the busbar 1.

In the electrostatic precipitator 3, a device for introducing a current-carrying busbar 1 of which is made according to the invention. The gas mixture of the electrostatic precipitator is held outside the insulator and does not reduce its insulating properties. The busbar 1, and with it the system of discharge electrodes can continuously shake without mechanically loading the insulator 6.

This contributes to reliable operation of the electrostatic precipitator with an overpressure varying widely.
