Industrial staticelectricity twin-core vertical oil mist clarifier
The utility model relates to a kind of static oil mist purifier, relates in particular to a kind of industrial staticelectricity twin-core vertical oil mist clarifier.
At present, at turnning and milling, bore in process of metal working such as mill grade, because the use meeting of metalworking fluid forms a large amount of oil mist particles in air.Research shows, in workshop, airborne maximum oil droplet footpath can reach 1 μ m.Pellet below 10 μ m can go directly and be deposited on lung, thereby causes bad health reaction.Particulate is less, and contained polycyclic aromatic hydrocarbon and heterocyclic compound are more, endangers also greatlyr, even can cause the illness such as lung cancer.Used cleaning equipment purification efficiency is low, and energy consumption is high, easily produce secondary pollution, and floor space is large.
Utility model content
The utility model provides a kind of industrial staticelectricity twin-core vertical oil mist clarifier, has solved the problems such as existing oil mist eliminator purification efficiency is low, clean-up effect is poor; It has purification efficiency high, do not need to change filter element, running resistance is low and facilitate clean and maintenance, save floor space, the advantage such as compact conformation.
The technical scheme that the utility model adopts is: industrial staticelectricity twin-core vertical oil mist clarifier, comprise: with the casing of access door, described casing is provided with air inlet and air outlet, in casing, by air inlet to air outlet, sets gradually oil mist separator, fore filter, electrostatic filter, the post-filter being connected, the blower fan chamber that is provided with blower fan; On oil mist separator, fore filter, electrostatic filter and post-filter, be equipped with slideway, between each filter and casing and access door, seal; Electrostatic filter comprises battery lead plate and wire electrode, between battery lead plate and wire electrode both positive and negative polarity, adopts oil resistant insulating ceramics to insulate, and battery lead plate and wire electrode intersect equidistantly to be arranged; On casing, be also provided with electric control unit, the position parallel with electric control unit is also provided with speed governing knob;
Described electrostatic filter is two, is communicated with and distributes up and down;
Described casing is the casing that carbon steel sheet is made;
The filter that described fore filter and post-filter are made by stainless steel wire braiding stack;
The top of post-filter is provided with safety switch;
Described blower fan adopts hypsokinesis centrifugal fan, and the impeller in blower fan adopts the steel plate after corrosion-resistance treatment;
The beneficial effects of the utility model are: adopt the level Four treatment facilities such as mist of oil separation, preposition filtration, electro static filtering, rearmounted filtration, purification efficiency is high, minimum purification to diameter 0.01 μ m oil mist particles; In use procedure, do not need to change filter material, compact equipment and every grade of filtration adopt drawer-type structure, and installation and maintenance are extremely convenient.Because electro static filtering section resistance is very little, and saved high efficiency filter material, so fan operation energy consumption is very little, noise is also low.
The design of employing vertical structure, has saved oil return apparatus, and oil return can directly be flowed back to lathe workspace through air inlet and be recycled, and has reduced floor space greatly, is applicable to supporting the use with various device.
This equipment increases speed-regulating function, and applicable different air quantity requirements, regulate rotation speed of fan to guarantee suitable air quantity demand.
The setting of safety switch has avoided high-tension electricity to hurt operating personnel.

The specific embodiment
Below in conjunction with accompanying drawing, 1-4 further illustrates the utility model: industrial staticelectricity twin-core vertical oil mist clarifier, comprise: with the casing of access door, described casing is provided with air inlet and air outlet, in described casing 13, by air inlet 5 to air outlet 6, sets gradually oil mist separator 1, fore filter 2, electrostatic filter 3, the post-filter 4 being connected, the blower fan chamber that is provided with blower fan 7; On oil mist separator 1, fore filter 2, electrostatic filter 3 and post-filter 4, be equipped with slideway, maintenance for convenience detach, sealing between each filter and casing 13 and access door 14, guarantees without leaking; Electrostatic filter 3 comprises battery lead plate 9 and wire electrode 10, between battery lead plate 9 and wire electrode 10 both positive and negative polarities, adopts oil resistant insulating ceramics to insulate, and battery lead plate 9 and wire electrode 10 intersect equidistantly to be arranged; On casing 13, be also provided with electric control unit 11, the position parallel with electric control unit 11 is also provided with speed governing knob 15; Electrostatic filter 3 comprises: battery lead plate 9 and wire electrode 10, and between battery lead plate 9 and wire electrode 10 both positive and negative polarities, adopt oil resistant insulating ceramics to insulate, battery lead plate 9 and wire electrode 10 intersect equidistantly to be arranged.
In order to improve clean-up effect, guarantee equipment dependability, adopt two electrostatic filters 3, cascade filtration unit further purifies; Blower fan 7 is set in blower fan chamber, and blower fan 7 adopts backswept centrifugal fan, and impeller blade adopts steel plate, and preservative treatment is carried out on surface.Electric control unit 11, comprising: the high pressure generator of 7KV and indicator lamp 8, there is the functions such as high voltage protective and operation indication, and this equipment increases speed-regulating function, and applicable different air quantity requirements regulate rotation speed of fan to guarantee suitable air quantity demand.The switch of safety switch and access door links, and appliance doors maloperation has been opened, and equipment autostop, in order to avoid high-tension electricity hurts operating personnel.
During equipment operation, open the gauge tap in electric control unit, blower fan 7 runnings, electrostatic filter 3 is charged, containing mist of oil air, from air inlet 5, enters, and by the centrifugation of oil mist separator 1, in mist of oil, bulky grain oil droplet is separated, and through air inlet 5, discharges; Less oil droplet enters after fore filter 2, aggregating into oil droplet discharges through air inlet 5, electrostatic filter 3 filters molecule in mist of oil, first oil mist particles is ionized, make its positively charged, the oil mist particles of positively charged is adsorbed on battery lead plate 9 while flowing through battery lead plate 9, is polymerized to oil droplet and discharges by air inlet 5, and post-filter 4 filters mainly for omitting mist of oil.Pure air is discharged from air outlet 6 through blower fan 7.This device increases electrostatic filter, before being arranged on post-filter, by not completely the further ionization of mist of oil of ionization absorption be adsorbed on again and on battery lead plate, aggregate into oil droplet.After purifying, air can directly drain into indoor.When filter need to clean, closing control switch, opens access door 14, can conveniently oil mist separator 1, fore filter 2, electrostatic filter 3, post-filter 4 be extracted out and be cleaned.
