Corona wire has astroid, twistedwire, fish-bone needlework, helix etc., and each discharge tip of existing corona wire is relative in corona wire
Heart line is equidistant, but the electric field of rectangular tube is opposite to four side central points by the distance on four vertex of tube hub to rectangle
Distance is remote, so that the discharge tip zone of action of corona wire is extended four vertex less than rectangle, forms charged blind area, cause small
Thus region passes through escape to part smoke exhaust, meanwhile, dust charged chance reduces, and the time of Charged migration so far prolongs
It is long, occur to neutralize and will increase with air-flow escape machine；In addition, existing corona wire carries out corona discharge on the same horizontal plane
Tip is one, every side, lazy weight, etc. under voltage strengths corona discharge intensity be short of, current density is small, is unevenly distributed, effectively
Operating distance is limited, so the dust-collecting efficiency relative drop under constant power situation, although increasing electric field length or improving work electricity
Compressive Strength can solve the above problems, but will increase construction cost, and fluctuation of service.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of asterism shape prickle coronas for box-section tubular electric field
