Abstract

The utility model discloses an absorption electrostatic cleaning mask, the lower end inlet of the draft duct in a smoke collection mask is provided with a crude-efficiency oil filter, the upper end outlet of the draft duct is provided with an electrostatic clarifier; as a lampblack exhaust mask is provided with the crude-efficiency oil filter and the electrostatic clarifier, the lampblack coming into the smoke collection mask is deoiled and clarified two times, after big oil-fog particles in the lampblack strike the oil filtering sheets of the crude-efficiency oil filter, the big oil-fog particles are cooled and adhered to the oil filtering sheets and flowed into an oil tank through an oil drain hole; the flue gas exhausted from the upper part of the crude-efficiency oil filter still contains micro lampblack-bearing particles, after the flue gas comes into the electric field room of the clarifier, the flue gas is ionized, a large amount of dust charges are formed in the flue gas, all lampblack particles with the charges are driven to dust collection electrodes by the action of the electric field force, the flue gas particles with remanent oil dirt discharge the borne charges collected on the dust collection electrodes, the exhausted lampblack gas is thoroughly clarified, and in addition, as an operation door is arranged on the smoke collection mask, the maintenance and the cleaning are more convenient.

Description

The adsorption electrostatic purification cover

Technical field:

The utility model relates to a kind of fume exhaust cover, more particularly relates to a kind of adsorption electrostatic purification cover, is used for the improvement and the control of kitchen fume.

Background technology

At present; from the restaurant and a large amount of oil smoke of producing of kitchen Fried, fried, cooked, fried dish generally just directly be discharged into outdoor by the air-introduced machine of enclosure rear end; so not only polluted the city air ambient, but also on air-introduced machine, overworked grease; greatly reduce the smoke evacuation ability and the service life of air-introduced machine; though also there is inlet at air-introduced machine to install " U " shape or the tile shape oil filtering grid that is overlapping additional; but oil removal efficiency is low; the oil smoke of a large amount of molecules still has been discharged into outdoor, can not satisfy the requirement of city environmental protection far away.

Summary of the invention:

The purpose of this utility model provides a kind of adsorption electrostatic purification cover; it can not only leach oarse-grained greasy dirt in outdoor discharging oil smoke from flue gas; prevent that contaminated environment and air-introduced machine be stained with the extension grease, the greasy dirt of molecule can also be leached simultaneously, can satisfy the requirement of city environmental protection.

The purpose of this utility model is achieved in that it includes exhaust fume collecting hood, it is characterized in that the following end entrance of ventilating duct is equipped with thick effect oil-filtering apparatus in exhaust fume collecting hood, and the upper end outlet of ventilating duct is provided with electrostatic cleaner.

Owing to thick effect oil-filtering apparatus and electrostatic cleaner are housed in exhaust fume collecting hood successively, enter of the purification of the interior oil smoke of exhaust fume collecting hood like this through twice different modes; Big oil mist particles in the oil smoke, after clashing into thick oil strain sheet of imitating on the oil-filtering apparatus several times, cooling is adsorbed on the oil strain sheet, flows into oil groove by outage again when knot gathers into big oil droplet; From the flue gas that discharge thick effect oil-filtering apparatus top through purifying, also be wrapped with small oil-containing flue gas particle, after this flue gas enters into the electric field space of electrostatic cleaner, make flue gas ionization, it is charged to form a large amount of flue dust in flue gas, all driven under the effect of electric field force toward dust collecting electrode with charged smoke particle, the flue gas particle of residual greasy dirt is emitted the electrically charged heavy collection of institute on dust collecting electrode, makes to be discharged to outdoor soot gas and to be purified completely; Also be suitable for simultaneously family and use, have simple in structure, fume purifying thoroughly, safeguard and clear up characteristics easily, be a kind of novelty and show unique characteristics remove fume purifying apparatus.

Description of drawings:

Fig. 1 is a concrete structure schematic diagram of the present utility model.

Fig. 2 is the right apparent structure schematic diagram of Fig. 1.

The specific embodiment:

In Fig. 1-2, the exhaust gases passes inlet of exhaust fume collecting hood 5 is welded with oblique carriage 4, the pair of parallel slideway is housed on carriage 4, thick effect oil-filtering apparatus is an oil filtering grid 3, oil filtering grid 3 is installed on the carriage 4 by slideway is oblique, seal the exhaust gases passes inlet in the exhaust fume collecting hood 5, make the flue gas that enters in the exhaust fume collecting hood 5 carry out gas cleaning by grating 3.Front at exhaust fume collecting hood 5 also is equipped with actuating doors 6, exhaust gases passes epicoele in the actuating doors 6 is welded with support 2, on support 2, be welded with two parallel slideways, box electrostatic cleaner 1 is placing on the slideway of exhaust gases passes epicoele by actuating doors 6 above the oil filtering grid 3, seals the outlet of the exhaust gases passes in the exhaust fume collecting hood 5.The thick oil-filtering apparatus of imitating oil-filtering apparatus or adopting honeycomb, netted, watt shape and V-type sheet, U matrix structure.

During use, after kitchen generation oil smoke starts air-introduced machine, produce negative pressure between the grid sheet of the electric field space of electrostatic cleaner 1 and oil filtering grid 3, the flue gas of band greasy dirt at first enters in the curved groove of oil filtering grid 3, wrap up in the bigger oil particles that contains of Tibetan in the flue gas, behind the curve oil strain groove of multiple impact grid sheet convex-concave, cooling attaches on the grid sheet, flows into oil groove by outage after knot gathers into oil droplet.From the thick flue gas that purifies of warp that oil filtering grid 3 is discharged, also wrap up in and keep the small greasy dirt particulate smoke that contains, after this flue gas enters into the electric field space of electrostatic cleaner 1, make flue gas ionization, it is charged to form a large amount of flue dust in flue gas, under the effect of electric field force, all driven toward dust collecting electrode with charged oil smoke, residual greasy dirt particle is emitted the electrically charged and heavy collection of institute on dust collecting electrode, makes to be discharged to outdoor soot gas and to obtain all purifying up hill and dale.

Claims (3)

1, a kind of adsorption electrostatic purification cover, it includes exhaust fume collecting hood, it is characterized in that end entrance is equipped with thick effect oil-filtering apparatus under the ventilating duct in exhaust fume collecting hood, and the upper end outlet of ventilating duct is provided with electrostatic cleaner.

2, purification cover according to claim 1 is characterized in that said exhaust fume collecting hood is equipped with actuating doors in its front.

3, purification cover according to claim 1 is characterized in that the electrostatic cleaner that said ventilating duct upper end is provided with places on the slideway of exhaust gases passes epicoele.
