Abstract

The utility model relates to an environmental protection type kitchen fume exhausting device, which solves the problems of the existing fume exhausting device that a large amount of oil dirt is left in the mechanism and pollution is caused by an exhaust opening. The utility model is composed of an aspirator, an air pipe, an axial fan, a purifier and an exhaust device. The utility model is characterized in that the purifier adopts the oil filtering method of water penetration wetting type, so the pollution to the air and an outdoor wall caused by exhausted gas is avoided. The utility model is especially suitable for restaurants, hotels and families.

Description

Environment-friendly type kitchen fume exhaust device

The utility model relates to environmental protection kitchen fume exhaust device.

Ventilation fan, the smoke exhaust ventilator of present kitchen pump drainage oil smoke, the oil smoke that can effectively culinary art be produced is discharged outdoor, but, its smoke pumping efficient is lower, in smoke exhaust ventilator, stayed a large amount of greases, be difficult to clean, on the exhaust outlet of outdoor directly external mist extractor, the greasy dirt that condenses is along with rainwater pollutes into the black greasy dirt field of a dirt to window and exterior wall, this phenomenal field city is seen everywhere, particularly the external oil extraction mouth in the kitchen in hotel, restaurant a slice is polluted, and has a strong impact on the healthy living of surrounding resident.Analyze general kitchen and adorning high-power exhaust gear (high-power ventilation blower in succession a bucket type gas skirt), summer, still temperature height between the kitchen, and why like this abundant residues oil smoke is arranged,, be because ventilating fan work, when air flows, the irregular play up and down of inside air micelle, smooth and easy mobile generation hinders to air, and resistance is strong more along with the rising of temperature.Therefore in face of the intake negative-pressure that present mist extractor mechanism is produced, oil smoke, the aqueous vapor of cooking evaporation, and the thermal current that the kitchen range internal combustion produces is a kind of mixed airflow high than ambient air temperature, because density contrast, by around the low air extrusion of relative temperature and rising, intake negative-pressure priming and natural convection air have been quickened air and have been mixed disorderly speed.Therefore, in the air-flow during intake negative-pressure is inhaled, thermal current siphons away to such an extent that lack than cold airflow.Therefore present substitute the flowing velocity that the mechanism of qi structure has just quickened air, and do not reduce or change Air mixing turbulent flow phenomenon.Thereby in smoke pumping mechanism residual a large amount of grease, outdoor window and wall pollute.

The purpose of this utility model is to overcome above-mentioned deficiency, a kind of environment-friendly type fume exhaust device is provided, kitchen range top rising thermal current (mixing air of oil smoke, steam and combustion heat air-flow) is strapped on the suction face allows it siphon away, so that reduce mixing with cold air (the relative low air of peripheral temperature), and then externally mist extractor carries out purified treatment, reduce grease, eliminate outdoor body of wall and pollute.

The utility model is achieved in that by aspirator, ventilation duct, axial fan, clarifier, exhaust apparatus and constitutes.Aspirator is that a side is down trapezoidal box, and there are a plurality of seam air entries in the front, is provided with multilayer aluminium orifice plate in the box, and the lower end is provided with sewage sump, feculence box, and the upper end is provided with the gas outlet; Clarifier adopts drawer structure and discharge duct to form an integral body, form by preceding sealing plate, the base plate that leaks, fixed frame, many group infiltration plates, infiltration plate top is a water service pipe, the micropore that infiltration is arranged above the water service pipe, be wrapped with synthetic cotton around the water service pipe, and to following extension, and constitute sheet infiltration body with wire netting clamping water service pipe; Exhaust apparatus adopts the V-arrangement body, and exhaust outlet is opened in the pipeline both sides, and the bottom is provided with sewage pipe.

Good effect of the present utility model is to handle through twice blowdown, especially through infiltration moistening type oil strain, avoided discharging the pollution of gas to air, and the pollution of outdoor body of wall.

Below in conjunction with accompanying drawing the utility model is described in further detail:

The utility model is made up of aspirator 1, ventilation duct 2, axial fan 3, clarifier 4, exhaust apparatus 5.Aspirator 1 is that a side is down trapezoidal box, and there are a plurality of seam air entries 6 in the front, and the inside is provided with multilayer aluminium orifice plate 7 in the box, and the lower end is provided with sewage sump 8, feculence box 9, and the upper end is provided with gas outlet 10.Clarifier 4 adopts drawer structure and discharge duct to form an integral body, form by preceding sealing plate 11, the base plate 12 that leaks, fixed frame 13, many group infiltration plates 14, infiltration plate top is a broken line shape water service pipe 15, the micropore that infiltration is arranged above the water service pipe, be wrapped with synthetic cotton and to following extension around the soakaway trench, and constitute the sheet body that seeps water with wire netting clamping water service pipe.Exhaust apparatus 5 adopts the V-arrangement body, and exhaust outlet 16 is opened in the pipeline both sides, and the bottom is provided with sewage pipe 17, and exhaust outlet is gone to the bottom and is the arm of angle, and ventilation duct 2 cross sections can be rectangle, also can be circle.

During culinary art, thermal current is under intake negative-pressure priming and cross-ventilated effect, enter aspirator 1 from a plurality of seam air inlets 6, when passing through the hole of aluminium orifice plate 7, part thermal current is met condensation and is formed oil, enter oil trap 8, oil collection box 9, most thermal current is through the gas outlet 10, ventilation duct 2, axial fan 3 and enter clarifier 4, in clarifier 4, the infiltration micropore of the water in the water service pipe 15 on pipe infiltrates synthetic cotton and wire netting forms infiltration plate 14, and thermal current process infiltration plate is through cooling, the overwhelming majority condenses into oil, oil water mixture is discharged through sewage pipe 17, and what discharge through exhaust outlet 16 is the gas of cleaning, has avoided the pollution to body of wall.
