Abstract

The utility model provides an electrostatic cooking fume cleaner, belonging to the fume purification device, wherein, an earth-plate electrode of an electrostatic dust removal is changed to a discharging electrode formed by a circulation water line, a high voltage electrode is a collecting electrode; when the utility model is used, the atomization of a grounding thin water line forms a thin and even water film on a surface of the high voltage collecting electrode. As the utility model adopts an electrode structure, a discharging mode and an oil-water separation measure, the utility model can realize the fume purification constantly and stably and high efficiently; therefore, the utility model has the advantages of compact structure, low manufacturing and running costs, no erosive phenomenon of materials, and repeated utilization of washing water; moreover, the utility model can normally run in extremely cold weather.

Description

The water electrode electrostatic oil and smoke cleaner

The utility model belongs to fume purifier of fume, adopts ground connection water electrode discharging atomizing corona discharge to carry out the wet electrostatic gas purification.When guaranteeing operation steady in a long-term, reach anticorrosion, noiseless, no stink and without sewage discharge.

At present, in the known cooking fume remover,, all can't remove and normally to move for a long time because of mist of oil is too sticking if adopt traditional electrostatic precipitation and dust removal by filtration.As adopt other traditional dust collection methods, also too low because of the too thin gas purification efficiency of mist of oil.The current fume purifying method that does not also have a kind of efficient stable is more carried less than solving problems such as burn into noise, stink and sewage discharge simultaneously.

The purpose of this utility model is to adopt new discharge mechanism in electrostatic precipitation, thereby washes high-field electrode and earth electrode in equipment running process at any time.In efficient removal mist of oil and pernicious gas, at any time recirculated water is purified and water-oil separating, be applicable to the gas purification of high viscosity flue dust.

The purpose of this utility model is achieved in that and changes the ground connection pole plate in traditional electrostatic precipitation into formed by the recirculated water line sparking electrode, and high-field electrode is as passive electrode.In running, the atomization gas discharge of the thin waterline of ground connection has good gas purification function, and the little water droplet that atomizing forms flies to passive electrode at a high speed and forms thin and uniform moisture film at the high pressure collecting electrode surface, thereby all electrodes all can keep clean at any time.The thin waterline of ground connection also can be removed stink and the harmful chemical analysis of part in the recirculated water when atomization gas discharges, adopted self-cleaning filter and high-pressure electrostatic oil water separator again in addition, and recirculated water can use for a long time and need not change.Because sparking electrode is water electrode, general insulating materials all can be adopted in corrosion-prone position in the traditional wet electrostatic precipitator, has not only prolonged service life of equipment but also reduced cost.

Owing to have These characteristics, this kind deduster is not only applicable to the purification of oil smoke of catering industry, and is applicable to the purification of all viscosity, low resistivity fine solid particle.

Below in conjunction with accompanying drawing the utility model is further specified.

Accompanying drawing 1 is a square-section water electrode electrostatic oil and smoke cleaner structural representation; Accompanying drawing 2 is a circular cross-section water electrode electrostatic oil and smoke cleaner structural representation.

1. range hoods, 2. oil smoke, 3. shells, 4. nozzles, 5. side water tanks, 6. upper water boxs, 7. plane pole plates, 8. high-field electrodes, 9. insulators, 10. high voltage sourcies, 11. flashback tanks, 12. valves, 13. filters, 14. water pumps, 15. reversal valves, 16. valves, 17. oil water separators, 18. waste oil that enter the mouth concentrate case 19. valves 20. LLCVs 21. gland steam exhausters 22. water outs 23. air-introduced machines 24. spray throwers among the figure

After starting clarifier, high voltage source (10), air-introduced machine (23), valve (16) and water pump (14) are opened, and valve (12) is closed.After the water of oil water separator (17) lining was drawn out of, automatic-closing valve (16) and Open valve (12) formed the water circulation.

Processed oil smoke is sucked by range hood (1), and enters clarifier through oil smoke inlet (2) and spray thrower (24).Water purifier shell (3) is made of plastics.At first, side water tank (5) supplies water to nozzle (4) and forms the vertical thin waterline of numerous ground connection, and thin waterline discharging atomizing efficiently purifies oil smoke under the effect of high-field electrode (8).Then, upper water box (6) forms the ground plane electrode through overflow on plane pole plate (7) surface, under the effect of high-field electrode, further remove by charged tiny oil droplet, gas after being cleaned is discharged by air-introduced machine (23), air-introduced machine and insulator (9) need not be safeguarded because of the long-time running of not contaminated energy.The oil droplet that the water electrode band in the flue gas flows into flashback tank (11) through water out (22) downwards, passes through filter (13) and water pump again and enters upper water box and side water tank, thereby realize periodical feeding.

In case close water purifier, air-introduced machine and water pump turn-off and valve (16) is opened, and the water of upper water box and side water tank flows down filter rinsed through reversal valve (15), and flows into oil water separator (17) through valve (16).Meanwhile high voltage source (10) continues power supply, but because of water electrode disappears so clarifier is not worked, and this moment, oil water separator carried out water-oil separating under the high pressure effect.Through one give the water-oil separating of fixing time after, valve (19) is opened, running water pipe is to the oil water separator supplementing water.LLCV (20) control amount of makeup water makes it just the waste oil layer be overflowed into waste oil and concentrates case (18).Automatically close full machine then, waste oil concentrates wait start next time in the concentrated case of waste oil after, so that taking-up and transportation.The steam that gland steam exhauster (21) produces when at any time waste oil being concentrated is discharged.
