Description
Technical field
The utility model relates to a kind of improved corona wire in the electric cleaner, belongs to flue dedusting technology field.
Background technology
In large industrial enterprises such as power plant, the flue dedusting work that is absolutely necessary.In numerous flue cleaners, the application of electric cleaner is comparatively extensive.The space primary structure that gathers dust of electric cleaner is dust collecting pole plate and corona wire.Corona wire connects the negative pole of DC high-voltage power supply, dust collecting pole plate connect positive pole ().Between corona wire and dust collecting pole plate, apply sufficiently high negative dc voltage, produce electric field between corona wire and the dust collecting pole plate, gas ionization around the corona wire, produce corona discharge, generate a large amount of positive and negative ion, anion moves to dust collecting pole plate, cation moves to corona wire, negative ions meets with ash-laden gas by the space of gathering dust in motion process and combines, and becomes charged dust, drops at last on dust collecting pole plate and the corona wire.When dust deposit behind certain thickness, take methods such as mechanical vibrator that it is removed, fall into the bottom ash bucket.In technical process in the past, the focal point of collecting dust only is placed on the dust collecting pole plate, and people constantly improve its structure and shape preventing reentrainment of dust, and for the cathode rapping of corona wire, people's understanding only limits to keep its good discharge performance.But find in actual applications, laying dust on the corona wire becomes reentrainment of dust dispersing again through the overwhelming majority behind the cathode rapping in the space of gathering dust, this is actually a kind of huge waste and destruction, a large amount of electric energy that cation gathers dust had both been wasted, make a large amount of cations and positively charged dust be dispersed into the space of gathering dust again, thereby destroyed the environment that normally gathers dust of negative electrical charge.
In addition, from the corona wire structure type of present use, serve as at most with the RS tubular barbed wire, secondly be fish-bone needlework, helix, jaggies etc., these corona wires respectively have its characteristics, are adapted to various electric cleaner.But its common shortcoming then is the positive charge dust to be caught collect poor-performing, and the laying dust when vibration dust-cleaning on the corona wire almost all becomes reentrainment of dust, has only low amounts of dust to fall into the bottom ash bucket; In addition, above-mentioned corona wire is in case after typing installs and put into operation, if when finding that its electric property does not meet operating mode and needs, also can't adjust the discharge parameter of corona wire.And in actual applications, institute's smoke discharging, dust also can cause some to change owing to the difference of fuel quality, burning condition etc., thereby corona wire is also had different requirements.Therefore, design and fully to collect dust, the elimination reentrainment of dust that deposits on the corona wire, and require to raising efficiency of dust collection, energy savings great effect to be arranged with the discharge of regulating corona wire according to difference.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the shortcoming of existing corona wire and a kind of laying dust of can effectively collecting is provided, and discharge adjustable electric hachure conveniently adjusted, that be used for electric cleaner.
The technical scheme that addresses the above problem is:

Another kind of organization plan of the present utility model is:
A kind of discharge adjustable electric hachure that is used for electric cleaner, it is made up of wide gripper shoe, prickle, adjustable plate, wide gripper shoe is the rectangle metallic plate, at it adjustable plate is set each side, adjustable plate also is a strip metal plate, and its length is identical with wide gripper shoe, at the outward flange horizontal interval, long limit of adjustable plate configuration prickle, at least be provided with two lateral adjustments slotted holes on each adjustable plate, fix at this and wide gripper shoe by fastening bolt.
For ease of gathering dust, the above-mentioned discharge adjustable electric hachure that is used for electric cleaner respectively is provided with windproof ditch plate in former and later two sides of corona wire, and windproof ditch plate also is a stripe board, and its cross section is imitative " L " shape, is vertically fixed on the adjustable plate near the prickle place.
The above-mentioned discharge adjustable electric hachure that is used for electric cleaner, the cross sectional shape of its wide gripper shoe be plate shaped, waveform, corrugation shape or middle for the pipe both sides be a kind of in plate shaped, waveform, the corrugation shape.
The above-mentioned discharge adjustable electric hachure that is used for electric cleaner, the shape of prickle can be triangle, rectangle, trapezoidal, knife-edge or aciculiform.
The above-mentioned discharge adjustable electric hachure that is used for electric cleaner, the width of its wide gripper shoe is more than 40mm; The width of prickle is 20-30mm, and length is 20-60mm; Be spaced apart 20-100mm between the prickle.
Corona wire according to the utility model making, owing on gripper shoe, be provided with adjustable plate, regulate relative position between the two, can change the equivalence discharge length of prickle, or the electrostatic screen effect is changed, the strength of discharge of corona wire is also changed thereupon, to adapt to different flue gases, dust needs to electric dust collector.Wide gripper shoe and windproof ditch plate can also play the good effect of gathering dust, and this will improve the efficiency of dust collection of cathodic electricity hachure in the electric cleaner greatly.The utility model is simple in structure, and only the structure of corona wire itself can realize the multiple function in the conventional cathode device.
