Description

Improved static oil-collecting dirt unit

The utility model relates to static oil-collecting dirt unit, particularly to the improvement of static oil-collecting dirt unit pole plate.

Along with being showing improvement or progress day by day of epoch, and the rapid development of industry and commerce, the utilization scope of static oil-collecting dirt is more and more widely, large-scale oil removing dirt facility such as range hood or fast food restaurant, dining room etc. as family all can use, its principle is to utilize at preposition high pressure section with the free oily dirt of flowing through between high voltage discharge electrode and collector plate of electrion mode, make it polarityization and can be when the low pressure stage that enters subsequently, can be adsorbed on the pole plate with different electric charge, be the cleaned air of no oily dirt and make the gas of being discharged after this handles; Yet, because the high pressure collector plate in traditional static oil-collecting dirt unit is to be arranged to the planar sheet form, so that in use for lacking the power of bearing by the side pressure difference that air-flow produced at a high speed, and the situation that produces lateral bending arranged, this kind situation causes excessively approaching between collector plate and discharge electrode naturally, easily thereby produce the bad phenomenon of spark discharge or short circuit; Moreover, the oily dirt that is attached with on this high-pressure polar plate, cumulative rises must thereby be dripped downwards thereupon, because traditional high-pressure polar plate bottom is into the horizontal linear form, so downward oil droplet is to drip everywhere to the bottom, the oily dirt of normal generation is just dropped on the high pressure pole axis pollute, and then cause and closely connect discharge, more severe patient directly forms the shortcomings such as accident of short circuit, for this reason, the necessity that is improved is arranged in fact.

In addition, traditional static oil-collecting dirt unit is in sucking the gas part, owing to do not see the design that air ducting is arranged, the gas that order sucks may pass through towards the upper and lower bypass with voltage main frame, so that the gas that sucks has been flowed through the pole plate part and has been polarized and collect, cause oily dirt in this local air flow because of the oily dirt of unprocessed elimination promptly discharges, cause having the unconspicuous shortcoming of dust removing effects.

Because the high-pressure polar plate of common static oil-collecting dirt unit still has above-mentioned shortcoming, so this creator is at its shortcoming, grind the road of improvement deeply, generation of the present utility model is arranged finally.

Main purpose of the present utility model promptly is intended to for solving the aforesaid drawbacks, and a kind of improved static oil-collecting dirt unit is provided, and can solve oily dirt and directly drip to pole axis from pole plate and produce the phenomenon that closely connects discharge or short circuit, and have preferable oil removing dirt effect.

For this reason, the utility model mainly is to be provided with at least one bending on the high-pressure polar plate face in being installed in static oil-collecting dirt unit, makes pole plate have preferable lateral strength by this bending; And the bottom of pole plate place is formed with inclined conducting, just is offset to position (the place ahead or rear position) beyond the discharge electrode top by the minimum point of this inclined conducting; Also can be provided with an air guide member, be installed in the lateral margin up and down of unit entry position in suction place of static oil-collecting dirt unit.

This shows, the utility model can make suitable this inclined conducting drip of oil droplet to the inclined conducting minimum point, drip again in oil trap, has the unexpected function of avoiding the direct drip of oil droplet to pole axis to cause closely connecing discharge or short circuit, the plane pole plate plate body lateral strength that can improve conventional electrostatic oil-collecting dirt unit is relatively poor, and often takes place to drop to the shortcoming that the high pressure pole axis produces short circuit because of oily dirt from high-pressure polar plate between high-pressure stage; Moreover utilize the setting of air guide member, and can make the oily dirt gas of suction, concentrate gesture towards the electrode unit through the guiding of air guide member, cross the electrodeless unit part of unit upper and lower sides to prevent the direct bypass of air-flow, and make it have preferable oil removing dirt effect.

As for detailed construction of the present utility model, application principle, effect and effect, please refer to the explanation that following adjoint does can be understood completely.

The simple declaration of accompanying drawing:

Fig. 1 is a schematic perspective view of the present utility model;

Fig. 2 is a pole plate floor map of the present utility model;

Fig. 3 is a pole plate schematic cross-sectional view of the present utility model;

Fig. 4 is an embodiment side direction generalized section of the present utility model.

See also Fig. 1 and shown in Figure 4, the utility model mainly forms a static oil-collecting dirt unit by main element group structures such as side plate 10, a plurality of high pressure collector plate 1, high voltage discharge electrode 2 and low pressure pole plates 3; It is characterized in that: high pressure collector plate 1 is provided with at least one vertical or horizontal bending 11 (being to be provided with two roads in pole plate vertically to bend in the present embodiment), this bending 11 can make pole plate 1 have preferable lateral strength, be able to have and preferable bear the side direction blast and unbending ability, at least one end (bottom) of pole plate 1 is formed with inclined conducting 12, this inclined conducting 12 can be a straight line or camber line extends, and its lowermost end 121 just is offset to the place ahead or the rear position of high voltage discharge electrode 2, be attached on this pole plate 1 and gradually drip and under oily dirt, can carry over plate body flow to after the bottom, being guided to minimum point 121 along this bottom inclined conducting 12 again drips again, owing to the minimum point 121 of this inclined conducting 12 is that establish the position that deviates to beyond discharge electrode 2 tops, can avoid high voltage discharge electrode 2 directly to touch, and produce the shortcomings such as accident of near-end discharge or short circuit because of the oil droplet on the collector plate 1; Comprehensive it, it is relatively poor then must to use the plane pole plate plate body lateral strength of improving conventional electrostatic oil-collecting dirt unit, and the direct drip of collector plate oil droplet often takes place to discharge electrode, produces the shortcoming that closely connects discharge or short circuit.

The utility model can be provided with an air guide member 4 in the suction inlet place of static oil-collecting dirt unit in addition, this air guide member 4 is to be installed on the preceding unit edge, both sides up and down of high-field electrode 1,2, this air guide member 4 has the wind-guiding plate 41 to the inner pinching deflection of unit, oily dirt air-flow by the bootable suction of design of the wind-guiding plate 41 of air guide member 4, more inside concentrated area is towards the gesture of high-field electrode region, the zone that forces air-flow can act on by electrode fully, and make its polarization more complete and have a preferable oil-collecting dirt effect.
