Abstract
The utility model relates to a multi-pin discharging electrode electrostatic oil fume (dust) removing device which is composed of an air inlet, an assembly of a high voltage electrostatic field of an off-in type blower, a high voltage generator for negative ions, an air exhausting pipe, etc. The high voltage electrostatic field comprises an upper electric field and a lower electric field which are respectively composed of a plurality of unit pin rod shapes, and the upper electric field and the lower electric field have the same structure. The utility model is characterized in that a pin rod-shaped discharging electrode has a multi-pin structure; the top end of the rod-shaped discharging electrode is provided with a pin-shaped discharging electrode; the upper part and the lower part of the circumference of a rod are respectively provided with two layers or more than two layers of pin-shaped discharging electrodes at a definite interval; the pin-shaped electrodes which are adjacent from top to bottom are arranged in a crossed mode in a space; a distance between pins and a distance between a pin at the edge and the edge of a dust collecting plate are equal; the two distances (h) satisfy an equation that h is equal to (1.5-2) d, d is equal to a distance between the center of a unit discharging electrode and a dust collecting polar plate, and the length of the pin is within the range of 5-9 mm.
Description
The utility model discloses a kind of spininess discharge electrode static flue gas removing (dirt) equipment, belong to the isolation technics class.
As everyone knows, utilize the high-pressure electrostatic absorption, the device category that airborne dust is separated is a lot of.The electrostatic air cleaner of patent 93226519.7 for example, its primary structure are that the thin space honeycomb needle bar by two same structures is in series, and apply long-acting bactericidal agent in the electric field on the collecting plate, will sterilize after the airborne dust absorption.Also be provided with active carbon filtering device in the clarifier, can filter out toxic gas in the air, but because the discharge electrode of single needle structure, the absorption efficiency of dust collection is not high.The oil smoke gas equipment kind of utilizing the static absorption to remove in the kitchen is also many, but that produced at present and use kitchen static flue gas removing machine, its cell discharge utmost point also is the single needle structure, promptly only place a needle-shaped discharging electrode in bar-shaped discharge electrode end, its absorption ability is very restricted, and influence removes the oil smoke effect.
The purpose of this utility model is to improve the efficiency of dust collection of static flue gas removing (dirt) equipment, discloses a kind of spininess discharge electrode static flue gas removing (dirt) equipment.
The utility model is achieved like this, adopt the air inlet in the existing electrostatic precipitator, centrifugal fan, high-pressure electrostatic field assembly, anion high pressure generator and exhaust duct etc., said high voltage electric field also can be series connection up and down, several cellular constructions that structure is identical, dust collecting electrode cross section, unit can be square or are honeycomb (hexagon), also can be circle or ellipse, but pole plate punch die moulding welding location constitutes the collecting plate assembly, is connected to the positive pole of high pressure generator by lead; It is fixing by the supporting of the frame of screen work more than that the needle bar shape discharge electrode is in each cell electrode of dust collecting electrode center, unit, constitutes the discharge electrode assembly, and be connected to the negative pole of high pressure generator with lead.It is characterized in that the needle bar shape very spininess structure of discharging, the bar-shaped discharge electrode in unit is except a needle-shaped discharging electrode is settled in the end, on around the rod, each fixed interval is mounted with two layers or more needle-shaped discharging electrode down, neighbouring needle electrode space is intersection and distributes, if following pin distributes to about excellent axis, then going up pin distributes at the fore-and-aft direction of axis, pin spacing and edge pins equate with the distance at collecting plate edge up and down, this two spacing (h) should satisfy h=(15～2) d, d is the distance of cell discharge utmost point center to pole plate, and pin long (being that needle point is to excellent discharge electrode centre distance) should be at 5～9mm.The theory and practice of electrostatic precipitation is told us, by the dust catching efficiency of deduster be and discharge electrode and dust collecting electrode between the space charge density (ρ) that forms of corona discharge and the scope (V) or the direct ratio of charge cloud, if grit more can obtain to level off to saturated charge and space electric field (E) is big more, the grit electric charge is subjected to electric field action power then more so, and the absorption effect is high more.The electrode of spininess structure can make under the equal voltage, and making corona current is one pole space charge be improved largely (about 50～120%).Compare with prior art constructions, charge cloud becomes charge cloud by limited part (around the stick end pin) and is full of whole electric field, thereby, grit can more likely be charged to saturated charge, and under the synergy of the electric field (F2) that Electrode Field (E1) and one pole space charge form, more may arrive dust collecting electrode, thereby improve efficiency of dust collection.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is unit in the utility model high-pressure electrostatic field structure.
Fig. 2 is the cross section structure of some unit of the present utility model dust collecting electrode.
Embodiment: with reference to the accompanying drawings 1,1 is the bar-shaped discharge electrode in unit among the figure, and 2 is needle-shaped discharging electrode, and they are in the center of unit electric field structure, and needle-shaped discharging electrode has two pins except pin of stick end on each determining deviation of the side of rod, and it is perpendicular to excellent axis.Last pin becomes square crossing to distribute with following pin, pin spacing and edge pins (the superiors or orlop pin) equate with the distance at dust collecting electrode edge, 3 is the unit collecting plate, and 4 is dust collecting electrode space, unit unipolar charge cloud scope, and Fig. 2 is a square for unit dust collecting electrode cross sectional shape.Typical utilization scope get the length of side (40～60mm), get length of side 55mm among the embodiment, pin spacing can be chosen at 30～45mm, gets 40mm among the embodiment, pin long (needle point is to the distance of excellent axis) is selected in 8mm.
The utility model fabrication and installation are convenient, and compared with prior art oil removing (dirt) efficient is significantly increased, and are that oil smoke (dirt) equipment is removed in the desirable kitchen of office, enterprises and institutions dining room and hotel.
