Technical background
Utilize the imagination of electrostatic precipitation, form in 19th century, the Huo Feierde (M.hohefelod) of Germany made and had demonstrated the device of electrostatic precipitation before and after 1820, and he has proved that electric spark can make smog dissipation in the vial that fills with smog.Britain physicist Lodge in 1883 at first proposes with the static clarification by air that smog polluted, British Wales one tame lead refinery in 1885 has built in the world, and first electric cleaner reclaims the not success of lead powder dirt, because lead oxide dust particle is superfine, very higher again than resistance, be difficult to capture, end in failure.California, United States university chemistry in 1907 is taught Cotterell (Cottrell) and made electric cleaner in the smog that captures sulfuric acid plant, obtained success, this is first electric cleaner that is successfully used to industrial gas purifying in the world, one of key that Cotterell is achieved success is exactly that sulfuric acid mist is lower than resistance, just in time is suitable for cottrell capture flue dust and compares resistance range.Hereafter, cottrell is applied in other industrial smoke pollutes rapidly.Over 100 years, electrostatic precipitation technology is that the human atmospheric environment of depending on for existence of Air Pollution Control, protection has been made significant contribution.But still point out in one's early years as White: " electrostatic precipitation technology is not fully realized far away, also has many phenomenons unintelligible ... ".
Cottrell is to utilize electric field action to pounce on the equipment of collection dusty gas.When two electrodes add the HVDC electric charge, just produce powerful non-uniform electric field, near corona plate, form a gas ionization zone, be called the corona zone.Electronics, anion and cation abrim in this zone.The radius of corona zone has only 2～3mm usually.The outside of corona is dizzy outskirt.Electronics in the corona current and anion (cation is because its zone of action is very little, and most dust are by electronics and anion absorption) will be adsorbed onto on the dust, make dust charged.Charged dust moves to dust collector pole under the effect of electric field force, is deposited on the dust collecting pole plate and with electric charge at last to discharge.When dust deposit arrives certain thickness, by rapping apparatus dust is gone into ash bucket clearly and discharge, finished separation process.Air behind the removing grit is discharged through dust-precipitator top exhaust outlet.
The cottrell main working parts is positive plate and cathode line.Cathode line is used for discharge, structures such as the different thorns with the homotype prickle of the different prickles of main employing are long, the design of positive plate is varied, the design of various battery lead plate forms mainly is that requirement secondary fly-up of dust when the pole plate rapping will lack, the distribution that vibrations that the pole plate each point is produced when guaranteeing rapping and acceleration help electric field will be considered processing, rigidity and the weight etc. of pole plate in addition.
The fishbone line is simple because of making, and the discharging efficiency height adopts the fishbone line many as the cottrell of cathode line, such as, the spacing of common cottrell two-plate is 23-28cm, and the negative electrode prickle is as shown below, and the needle-like prickle is welded on the utmost point pipe of metal circular tube.
The cathode line of this structure, a utmost point pipe length overall have 200 above prickles more than 5 meters on the utmost point pipe, the cottrell that long period uses, the thorn point of the every prickle spherical caking that all has been wrapped.These cakings are directly to influence electric field one of the principal element of operational effect of gathering dust, and in order to remove these cakings, unique way is the electric field that stops at present, treat that nature cooling back crawls into electric field inside by the operative employee, take manually to beat when opening mechanical vibrator.Factors such as however, many electric fields are still because of polar plate spacing is little, and hand labor intensity is big cause cleaning effect not good.
Summary of the invention
The object of the present invention is to provide a kind of cleaning rake that lumps on the cottrell negative electrode prickle of handling, to solve labor cleaning's drawbacks such as labour intensity is big, efficient is low of luming.
For achieving the above object, technical solution of the present invention is: a kind of cleaning rake that lumps on the cottrell negative electrode prickle of handling, comprise drag head, and it is characterized in that: a side of described drag head 1 is provided with rake teeth 2, and opposite side flexibly connects with rake arm 3.
Described rake teeth 2 is the open circles ring-type.
Described rake arm 3 is telescopes of being made by light material.
The invention has the beneficial effects as follows:
The clearance time of cottrell cathode line prickle thorn point shortens, and can effectively reduce the overhaul of the equipments time, improves equipment operating efficiency, increases the production capacity of whole system.
