Abstract

The utility model discloses a ventilation absorption electrostatic cleaning mask, the lower end inlet of the smoke exhaust duct in a smoke collection mask is provided with a crude-efficiency oil filter, an electrostatic clarifier is arranged in the smoke exhaust duct on the crude-efficiency oil filter, an induced draft fan is arranged at the outlet of the smoke exhaust duct above the electrostatic clarifier; as the induced draft fan is arranged in the smoke collection mask, the smoke collection mask and the induced draft fan are formed into an entity, so that the volume of the smoke exhaust apparatus is small, the draft efficiency is high, at the same time, oil-filtering grids and an electrostatic clarifier are arranged successively in the smoke collection mask, thus, the flue gas coming into the smoke collection mask is clarified through two different ways by the action of the induced draft fan, the exhausted lampblack gas is thoroughly clarified; simultaneously the utility model is suitable for using at families and has the advantages that the structure is simple, the volume is small, the room utilization is small, clarifying the lampblack is thorough, and the maintenance and the cleaning are convenient, the utility model is a novel and characteristic smoke exhaust cleaning apparatus.

Description

Ventilation adsorption electrostatic purification cover

Technical field:

The utility model relates to a kind of fume exhaust cover, more particularly relates to a kind of ventilation 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 through being arranged on outdoor air-introduced machine with the enclosure split by enclosure; Like this; cause the fume extractor volume big; the installation and maintenance trouble, air inducing efficient is low, can't use in less kitchen; not only polluted the city air ambient, but also on air-introduced machine grease easy to hang; 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, 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 ventilation adsorption electrostatic purification cover, and it not only makes air-introduced machine and exhaust fume collecting hood form one, and the fume extractor volume is little, installation and maintenance convenience, air inducing efficient height, can use in less kitchen; And, can will in outdoor discharging oil smoke, from flue gas, leach by oarse-grained greasy dirt, 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 to realize like this, it includes exhaust fume collecting hood, it is characterized in that end entrance is equipped with thick effect oil-filtering apparatus under the discharge flue in exhaust fume collecting hood, be provided with electrostatic cleaner in the discharge flue above thick effect oil-filtering apparatus, the discharge flue outlet on electrostatic cleaner also is equipped with air-introduced machine.

Because air-introduced machine is housed in exhaust fume collecting hood, exhaust fume collecting hood and air-introduced machine have formed one, make the fume extractor volume little, air inducing efficient height, installation and maintenance are convenient, simultaneously thick effect oil-filtering apparatus and electrostatic cleaner are installed successively in exhaust fume collecting hood, under the effect of air-introduced machine, make the purification of the oil smoke that enters in the 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 after 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, under the effect of electric field force, all driven toward dust collecting electrode with charged smoke particle, emitted the electrically charged heavy collection of institute on dust collecting electrode, make to be discharged to outdoor soot gas and to be purified completely at the flue gas particle of residual greasy dirt on the dust collecting electrode; Also be suitable for simultaneously family and use, have simple in structure, volume is little, space utilization is little, fume purifying is thorough, safeguard and clear up characteristics easily, be a kind of novelty and show unique characteristics except that 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, carriage 4 is screwed the discharge flue inlet at exhaust fume collecting hood 5, and slightly imitating oil-filtering apparatus is oil filtering grid 3, and oil filtering grid 3 places on the carriage 4, the oblique inlet of sealing the discharge flue lower end in the exhaust fume collecting hood 5.Be provided with bracket track 2 on the exhaust fume collecting hood above the oil filtering grid 35, box electrostatic cleaner 1 places on the bracket track 2, and the discharge flue outlet on box electrostatic cleaner 1 also is equipped with air-introduced machine 7.In exhaust fume collecting hood 5 by oil strain delete 3, electrostatic cleaner 1 constitutes a complete discharge flue.Front at exhaust fume collecting hood 5 also is equipped with actuating doors 6, can carry out oil strain is deleted 3 and installation, cleaning and the maintenance of electrostatic cleaner 1 by actuating doors 6.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 7, 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, is all driven under the effect of electric field force toward dust collecting electrode with charged oil smoke.On dust collecting electrode, it is electrically charged that residual greasy dirt particle is emitted institute, and heavy collection is on dust collecting electrode, makes to be discharged to outdoor soot gas and to obtain all purifying up hill and dale.

Claims
