The board-like electrostatic cleaner of coaxial sleeve control of dustTechnical field
The invention belongs to electrostatic precipitator field, particularly relate to the electrostatic cleaner being realized purification of air by coaxial sleeve cartridge type collecting plate.
Background technology
Electrostatic precipitator technology is widely applied in industrial production, and its principle is also constantly obtaining new development and application.Usual industrial electrostatic cleaner, the dust of its Electrostatic Absorption on fixing collecting electrode, generally adopt the mode of rapping to remove, not only complex structure, power consumption is large, also also exist insufficient on the vibration dust-cleaning of dust collecting electrode and affect the problem of efficiency of dust collection, being only applicable to industrial production dust removal field.Along with atmosphere pollution in recent years especially fog is more and more serious, people also more and more pay attention to air quality, in the process of attempting various air cleaning and cleaning principle and technology, find traditional filtering technique energy consumption and maintenance cost too high, and traditional electrostatic dust collection equipment is also because the limitation of self structure and efficiency is also difficult to the indoor air purification aspect being applied directly to non-field of industrial production.More the purifier of air cleaner used in everyday and air-conditioning, then belong to dust removal by filtration, need manually to pull down screen pack and carry out periodic cleaning, waste time and energy, also affect ventilation effect.From energy consumption and be maintained as originally, electrostatic precipitation philosophy and technique has huge advantage, if design rationally ingenious, can realize low energy consumption and low maintenance cost, be worth carrying out degree of depth innovation and technological development.
For solving the problem, people have invented crawler-type mobile dedusting plate and the board-like electrostatic cleaner of flexible fabric control of dust.Movable dust removal plate, developed by HIT at first, for improving the dust catching efficiency of high resistivity dust, it is the hinged annular tank band structure of rigid metal plate, a dust arrester forms by organizing tank band more, often organize tank band and all have independently rotation and deashing device, complex structure is applicable to large-scale electrostatic precipitator.On this basis, change rigidity tank band into flexible fabric, the collecting polar plate structure of flexible fabric has been invented by Ohio State Univ-Columbus USA, and overall structure still maintains the design of Hitachi, Ltd, the flexible fabric often organizing annular all has independently driving and deashing device, is applicable to large-scale dust collect plant.Recently, China technical specialist has invented again continuous winding and has moved control of dust plate type electrostatic dust removal machine (Chinese invention patent publication number: CN103008107A), other than ring type continuous winding structure taked by movable dust removal plate, only need one group to drive and deashing device, greatly simplify structure, reduce cost, be applicable to small-sized dust pelletizing system, and debris collection area and deashing region disconnecting, eliminate the problem etc. of reentrainment of dust during deashing.
Coaxial sleeve cartridge type collecting plate structure of the present invention adopts multiple telescopic nested form, and the automatic rotation removing dust and clearing ash device matched, optimize structure, reduce cost, add stability and the reliability of system, be specially adapted to middle-size and small-size dust pelletizing system, be applicable to producing in enormous quantities, be expected to obtain large-scale application in indoor fresh air dust removal field.

In such scheme, described sparking electrode is the frame structure of hollow, is also provided with the projection of pointed tooth shape outside the edge of sparking electrode.
In such scheme, described collecting plate and the material of sparking electrode are the conductive plate material of rigidity, can be stainless steel, iron or other conductive material.
In such scheme, described rotating ash removal device also can be a pair scraper plate with collecting plate close contact, utilizes scraper plate to wipe dust on collecting plate off.
In such scheme, described dust arrester also can be and liquid spraying device, adopts shower nozzle ejection cleaning fluid washing collecting plate.
Principle of the present invention is the collecting electrode adopted is the coaxial cylindrical conductive plate of rigidity, internal diameter is descending is nested to form tubular collecting plate array from level to level, increase the dust-collecting area of the collecting plate in unit volume, driving shaft is positioned at coaxial sleeve axle center and is driven by motor and rotates, transmit power to drive rod, drive the rotation brush roll that contacts with collecting plate or deashing scraper plate or liquid to spray movement and rotate, sweep dust.
The invention has the beneficial effects as follows:
Because its collecting plate is coaxial cylindrical, form nested array and maintain static, increase the dust-collecting area in unit volume, transmitting power by the driving shaft of driven by motor drives rotation brush roll or deashing scraper plate or liquid to spray to drive rod, the dust that collecting polar plate traps is swept completely, high resistivity dust can be trapped efficiently like this, simultaneously do not need to pull down carry out manual cleaning, can realize non-maintaining.This system architecture is simple, reliable and stable.Owing to taking unique coaxial sleeve tubular multi-dust collecting plate design and rotating ash removal apparatus design, greatly optimize structure, enhance function and stability, reduce cost, be applicable to producing in enormous quantities.
