Description
Technical field
The present invention relates to a kind ofly utilize high voltage electric field to separate and capture the graded efficient electric precipitator that is suspended in dust in the gas.
Background technology
With the dust in high-voltage dc separation and the captured gas, be in an airtight equipment, spaced negative electrode and anode to be installed, apply dc high-voltage to negative electrode, form high-voltage dc with the anode of ground connection, when dusty gas flows through, produce corona discharge between the two poles of the earth, make dust charged, charged dust is under the effect of electric field force, be attracted on negative electrode and the anode to two polar motions, go into the ash bucket discharge by the dust exfoliation that rapping will be adsorbed on the electrode, the gas that flows out electric precipitation is the clean gas after the dedusting.During the electric cleaner transmission operation, stable corona discharge need be arranged, send then efficiency of dust collection height of piezoelectric voltage height, the corona current that produces between the two poles of the earth is big, and electric field is many to the grit acting, and efficiency of dust collection is also high.Send electric situation except the influence that is subjected to process gas, also depend on negative electrode and the structure of anode and the coupling of different cathode line and positive plate.Suitable coupling, the starting voltage that produces corona discharge is lower, and spark discharge voltage and breakdown voltage are higher, the adjustable range of operating voltage is big, plate electric current on the positive plate is big and be evenly distributed, and electric cleaner can reach the running status of the best like this, obtains the highest efficiency of dust collection.Polar curve commonly used at present is a tubular barbed wire, pole plate is dull and stereotyped, the configuration of a this plate one line, the spine of cathode line is relatively large over against dull and stereotyped positive electric current, but depart from spine right plate face portion fail to make full use of, the current unevenness of pole plate is even, electric current is very little, and spine is shorter over against the vertical range of flat plate, has limited working voltage, influences dust collection efficiency and improves.
Existing up-to-date at present electric cleaner adopts shaped form or broken line shape positive plate to improve efficiency of dust collection, the patent No. is 92237767.7 disclosed electrostatic precipitator, it is the sinusoidal configuration at center that positive plate adopts with the cathode line, though increased specific collection area, but cathode line is a traditional structure, bloom, discharge effect are undesirable, and the cathode line arcing distance is non-adjustable, has greatly limited the practicality and the applicability of electrostatic precipitator.
Summary of the invention
For deficiency such as solve cathode line bloom in the prior art, discharge effect is undesirable, arcing distance is non-adjustable, efficiency of dust collection is low, the object of the invention provides a kind of simple in structure, convenient for production, the cathode line arcing distance is adjustable, the graded efficient electric precipitator that efficiency of dust collection is high.
In order to achieve the above object, the technical solution used in the present invention is: a kind of graded efficient electric precipitator comprises cathode line, be with the baffle plate type positive plate of the ditch that gathers dust, cathode line is the body with symmetrical two seamed edges, every positive plate cross section is converted into four foldings, form two embossed areas, the recessed district of adjacent two row's positive plates is to recessed district, the convex region is to the convex region, 2 recessed district symmetrical centre points of adjacent two row's positive plates are vertically arranged cathode line respectively, symmetry two seamed edges of cathode line face the recessed district of adjacent two row's positive plates respectively, its technical characterstic is on symmetry two seamed edges of described cathode line evenly the curved splinter of welding " Y " shape at interval, the curved splinter of " Y " shape on two seamed edges shifts to install, and two curved cusps of the curved splinter head of " Y " shape are respectively over against the two plate faces in the recessed district of positive plate; Be equidistant discharge between two curved cusps of the curved splinter of " Y " shape that cathode line is provided with and the pad-face, arcing distance is a little longer than the theoretical between the heteropole, a corona current and the breakdown voltage of cathode line are improved, efficiency of dust collection also improves thereupon, and the height of the curved splinter two curved cusps of available adjustment " Y " shape adapt to different same die openings from, make different model electric cleaner design and make more easy.
Further, the curved splinter of described " Y " shape is from top to bottom evenly fitted with the seamed edge of cathode line at interval, and seamed edge does not discharge, play shielding action, guarantee that the curved cusp discharge of the curved splinter of " Y " shape is strong, can form powerful electric wind, keep the good electricity condition that send, and do not influence mechanism's rapping dedusting.
Again further, be concatenated into anode arranged plate, can be equipped with corresponding cathode line group, be disposed in the electric cleaner of different capacity by the different demands of client by many positive plates.
The present invention adopts the curved cusp discharge of seamed edge shielding corona wire to cooperate the ditch baffle plate type positive plate that gathers dust, a plate is joined two lines, on the cross section of positive plate, be converted into four foldings and form two embossed areas, adjacent two row positive plates recessed district to recessed district, convex region to the convex region, in recess, arrange cathode line, two curved cusps of the curved splinter of " Y " shape are respectively over against the positive plate face, a corona current and a breakdown voltage of cathode line have been improved, thereby raising efficiency of dust collection, and can adjust the height of the curved splinter two curved cusps of " Y " shape, satisfy different capacity dedusting requirement, applied widely.
