Abstract
The utility model disclose a corona electrode concentricity adjustment device for a coking electric tar precipitator, which comprises a horizontal plate, wherein a through hole with a diameter of 3mm is arranged at the center of the horizontal plate, and handles are respectively arranged on the top surface of the horizontal plate at the two sides of the through hole; a tapered cylinder with a large upper opening and a small lower opening is arranged below the bottom surface of the horizontal plate, and the tapered cylinder and the through hole are axially arranged; the external diameter of the upper end of the tapered cylinder is the same as the internal diameter of the port of an anode tube of the tar precipitator, and vertically communicated notches are arranged on the surface of the horizontal plate and the wall of the tapered cylinder; the width of the opening end of the notch positioned at the periphery of the horizontal plate is 15mm, and the inner side end of the notch is communicated with the through hole; and the width of the opening of the inner side end of the notch is 3mm. The corona electrode concentricity adjustment device is adopted, so that the concentricity check work and adjustment alignment work can be completed by one action without recording data, and thus the overhaul procedure is simplified, the time is shortened, and the manpower and tool investment are reduced.
Description
Technical field
The utility model relates to a kind of coking electrical tar precipitator corona discharge electrode adjusting device, particularly coking electrical tar precipitator corona discharge electrode concentricity adjusting device.
Background technology
Coke-oven plant's 42 hole coke ovens use electrical tar precipitator to purify coke-stove gas, and the coke oven electrical tar precipitator adopts the cellular structure form.Its operation principle is to apply high voltage direct current between plain conductor and honeycomb metal tube wall, is enough to make gas to produce the electric field of ionization to keep, and makes and forms the corona zone between the anode and cathode.Press electric field theory, cation is adsorbed in electronegative corona discharge electrode, and anion is adsorbed in the receiving electrode of positively charged; All negative ions that are ionized all are full of the whole space between corona discharge electrode and the receiving electrode.When the coal gas that contains impurity such as tar droplet during by this electric field, the impurity that has adsorbed anion and electronics moves to that to discharge institute behind the receiving electrode electrically charged under the effect of electric field Coulomb force, and is adsorbed on the receiving electrode, thereby reach the purpose of Purge gas, be commonly referred to charged phenomenon.When the impurity level on being adsorbed in receiving electrode is increased to greater than its adhesive force, can discharge from the electrical tar precipitator bottom automatically to dirty time, the pure qi (oxygen) body then leaves and enters next procedure from electrical tar precipitator top.
The coking electrical tar precipitator is welded on the tube sheet of two ends by several steel pipes of 159 and forms honeycomb, is the center of circle with same vertical axis, and equidistant placement is formed receiving electrode together.Because the same sex between the corona discharge electrode is repelled each other. can make electric field little cavity, room occur, promptly the field intensity cave easily causes gas short circuit in the cave to run off, and reduces capturing effect.Because high, very strictness of Installation and Debugging that the accuracy of manufacture of concentric circles electrical tar precipitator requires, in making, install and transporting, concentricity, levelness and perpendicularity are changed, all can cause between the anode and cathode or between other parts and produce electric discharge phenomena, be difficult to meet the requirements of voltage, directly influence the arresting efficiency of tar, porcelain bobbin insulator is punctured damage.Because of the voltage change of field intensity is 400V/mm, so even occur the deviation of 1mm between anode and cathode, the changing value of its field intensity voltage can be up to 400V.So in use need constantly centering is checked and adjusted to the axiality of corona discharge electrode and receiving electrode.
Originally adjust corona discharge electrode and adopt backguy and look for the center of circle with Steel Ruler, adjust action and measure action mutual interference mutually, need constantly to repeat, efficient is very low.Because of the electric fishing maintenance downtime can not be of a specified duration excessively, and shutdown all needs to do complicated safety and cleaning preparation at every turn, just highlights so improve the importance of the efficient of corona discharge electrode adjustment centering.
Summary of the invention
The purpose of this utility model is to provide a kind of coking electrical tar precipitator corona discharge electrode concentricity adjusting device, it is simple in structure, can make axiality inspection work and action of adjustment centering work just can finish, need not record data, simplified overhaul procedure, shorten the time, reduced manpower and instrument input.
The purpose of this utility model is to realize like this, a kind of coking electrical tar precipitator corona discharge electrode concentricity adjusting device, this device comprises a level board, it is 3 millimeters through hole that the center of level board is being provided with a diameter, a handle is being set respectively on the level board end face of through hole both sides, the up big and down small circular cone tube of one opening is being set under the bottom surface of level board, circular cone tube and said through hole coaxial line are arranged, circular cone tube upper end external diameter is identical with tar device anode tube port internal diameter size, one gap that is communicated with up and down all is being set on the plate face of level board and on the cones wall, the open end width that gap is positioned at level board outer rim place is 15mm, the medial extremity of gap is connected with said through hole, and the A/F of gap medial extremity is 3mm.
When adjusting centering, the utility model is installed on the anode tube port from corona discharge electrode hanger downside, firm back is a benchmark with the anode tube, the mode of regulating the corona discharge electrode hook by spanner makes corona discharge electrode enter said lead to the hole site, when corona discharge electrode reaches through hole central authorities, promptly accuse and adjust successfully, with adjusting next root corona discharge electrode.
Adopt the utility model to make axiality inspection work and adjust action of centering work and just can finish, need not record data, simplified overhaul procedure, shortened the time, reduced manpower and instrument input.
