Abstract
The characteristic lies in that the insulation device connected between the grounding electrode and corona discharge electrode and high-voltage lead-in wire are all installed on the flue gas baffle above the upper port of the electric field cylinder body, under the actions of labyrinth seal of the large and small sheathings and the backward blowing implemented by the backward blowing pipe in the small sheathing and the induced draught fan, the dust exhausted from the upper port of the dust collecting electric field cylinder body is given no way to contact the high voltage insulating device and high voltage lead-in wire, thus the discharging due to getting fog on the high voltage insulating device and high voltage lead-in wire is completely avoided, and the reliable operation of electric dust collecting appliance is ensured.
Description
The present invention relates between corona discharge electrode that electricity gathers dust and the electric field cylindrical shell seal dewfall and climb the arc discharge problem.
To up to a hundred kilovolts, conventional insulating method utilizes high-voltage insulating system to implement in the electric field cylindrical shell to voltage between corona discharge electrode that electricity gathers dust and the electric field cylindrical shell up to tens kilovolts.Because temperature, the humidity of dust flue gas change very greatly, be easy at the seal surface sweating, cause that high pressure climbs arc discharge, this is for many years a big general character difficult problem in the industry, in order to address this problem, and the baking measure of once around seal, taking to heat of some producer, but because air velocity is very fast in the electric field cylindrical shell, most of temperature has been pulled away, so, still can not fundamentally avoid the dewfall on seal surface to climb the arc discharge problem.
The object of the present invention is achieved like this, and this dust collection electric field cylindrical shell can be processed into the structure of monotubular shape, MULTILAYER COMPOSITE tubular, square tube shape according to the size of handling air quantity.Monotubular shape---be provided with corona polar line (claiming corona discharge electrode among the figure) in the centre of electric field cylindrical shell earthing pole.The MULTILAYER COMPOSITE tubular---be provided with corona discharge electrode tube (claiming corona discharge electrode among the figure) in electric field cylindrical shell (claiming electric field cylindrical shell earthing pole among the figure) lining, also be provided with the little cylindrical shell (claiming electric field cylindrical shell earthing pole among the figure) that is connected with the electric field cylindrical shell again toward the inside, the middle corona polar line (claiming corona discharge electrode among the figure) of establishing.Square tube shape---be provided with pole plate (claiming electric field cylindrical shell earthing pole among the figure) and corona discharge electrode frame (claiming corona discharge electrode among the figure) in electric field cylindrical shell (claiming electric field cylindrical shell earthing pole among the figure) the inside.The rapping that it is characterized in that insulation between corona discharge electrode and the electric field cylindrical shell and high pressure inlet wire and corona discharge electrode is not implemented in electric field cylindrical shell the inside, but more than suitable for reading away from the electric field cylindrical shell of dust flue gas environment, implement the upper end of pressure gas baffle, flue gas can only pass through cylindrical shell place suitable for reading, presses the gas baffle lower end to discharge.Seal and high pressure inlet wire and corona discharge electrode rapping are all hung on press gas baffle and are connected enforcement.If smoke moisture is big especially, also the big sheath of seal that can establish on every side on press gas baffle is established the little sheath of seal in the seal upper end, establishes the reverse-blow pipe road in the upper end of little sheath, by air-introduced machine blowback wind is implemented on the seal surface.Owing to be provided with big sheath and little sheath around the seal, just formed labyrinth sealing between the flue gas for seal and cylindrical shell discharge suitable for reading like this, add the blowback wind of little sheath upper end, make the flue gas of cylindrical shell discharge suitable for reading can't touch high-voltage insulating system and high pressure inlet wire, thereby, thoroughly improve the Insulation Problems that electricity gathers dust, guaranteed the operation reliably and with long-term of electric dust collection device.
According to this principle, can also fix seal, support, hang in the natural environment in the dust collection electric field cylindrical shell outside, the crossbeam that supports or hang by seal is hung corona discharge electrode in the dust collection electric field cylindrical shell again, high pressure inlet wire and corona discharge electrode rapping all can be implemented in the natural environment of cylindrical shell outside, not influenced by dust flue gas, can play identical insulation effect equally.
