Abstract

The invention discloses a wind spiral-flow type oil fume eliminator by abandoning the traditional impeller rotating type oil fume eliminating method and utilizing a hydrocyclone to separate micron-size fine particles from a fluid medium. According to the wind spiral-flow type oil fume eliminator, high-speed spiral flow is generated through the hydrocyclone, oil fume can stay longer in a cyclone under the centrifugal action, so that oil fume, waste gas and unpleasant odors are eliminated more completely, purification efficiency is high, and cleaning is easy. Meanwhile, the wind spiral-flow type oil fume eliminator is simple in structure, convenient to install and low in cost. Under the condition that a proper hydrocyclone and a proper draught fan are adopted, the oil fume exhaust rate is 350 m<3>/h - 400 m<3>/h, and purification efficiency is good when the distance between a suction port and a cooking range is 800 mm and can reach 85% - 92% or even 95%. The wind spiral-flow type oil fume eliminator has a good effect on improving the emission of kitchen oil fume for the catering business. After the wind spiral-flow type oil fume eliminator is operated for a period of time, no greasy dirt is left on the wall of the cyclone, and self-cleaning is realized.

Description

A kind of wind-force spiral-flow type cooking fume remover
Technical field
This patent is abandoned conventional impellers rotary oil smoke purification method, utilizes cyclone can from fluid media (medium), isolate the fine particle of several microns, has designed a wind-force spiral-flow type cooking fume remover.
This wind-force spiral-flow type oil smoke cleaning device structure is simple, easy for installation, uses reliably, and super quality and competitive price, purifying rate is good, can in the kitchen in family, restaurant, be widely used.This technology not only can, for kitchen oil fume purifying, can also be applicable to the purification of vehicle exhaust equally.
Background technology
Traditional smoke exhaust ventilator is generally divided into two kinds of European and Chinese styles, the smoke evacuation principle of European-style range hood designs according to European eating habit, and they are in the majority with " decocting ", " stand ", and this culinary art gimmick is because temperature is lower, the oil smoke producing is few, and is conducive to the carrying out of separation process.And very hot oven quick-fried is liked in Chinese's cooking, what produce is dense smoke, so the defect of European-style range hood is very obvious, and Chinese style lampblack absorber is to drive wind wheel High Rotation Speed by motor, make to form negative pressuren zone in the certain space of cooking stove top, by indoor soot gas suction lampblack absorber inside, but the negative pressure region of the dark type smoke exhaust ventilator of great majority is about 0.14 cubic metre, its smoke exhaust efficiency is 60% left and right, and the negative pressure region of cabinet type smoke exhaust ventilator is about 0.32 cubic metre, and smoke exhaust efficiency is greater than 95%.But the form that has adopted three side sealing to close due to cabinet type range hood, so do not have in appearance suspension type to seem luxurious.
The oil smoke separation principle of traditional smoke exhaust ventilator is: soot gas filters through oil network, carrying out oil smoke for the first time separates, then enter inside, air channel, by the rotation of impeller, soot gas being carried out to oil smoke for the second time separates, oil smoke is subject to the effect of centrifugal force, mist of oil is aggregated into oil droplet, collects lubricating cup by oil circuit, and the flue gas of purification is finally discharged along fixing path.This separation being produced by vane rotary, because the time of oil smoke in eddy flow field is very short, has little time sedimentation separation, and therefore effect is poor.In addition because oil smoke adhesiveness is strong, filter medium is easy to blocked and loses filtration, and the filter medium polluting cannot cycling and reutilization, easily causes new pollution, uses after a period of time, sticks tobacco tar on impeller, is difficult to clean.
Summary of the invention
The detailed description of the invention operation principle and the property indices of wind-force vortex type fume exhaust fan.
Wind-force vortex type fume exhaust fan utilizes air as separating medium, when oil-contg. smoke body enters after cyclone with tangential direction, being spiral vortex state at a high speed moves with three-dimensional, under effect of centrifugal force, mist of oil is thrown to cylinder inner surface, the mutual polymerization of mist of oil that concentrates at cylinder inner surface forms large oil droplet, drops to gradually bottom timing and discharge under Action of Gravity Field.Due to the effect of centrifugal force field and the viscosity of mist of oil, make the very easily coalescent barrel of mist of oil in gas, clean-up effect is fine, and more than 90% mist of oil is removed under the effect of wind-force cyclone.Sucked and send back to atmosphere by blower fan through the air purifying.The particle that in oil smoke, density is little moves to centre, and moves upward along axis, finally discharges as overflow.Utilize cyclone can from fluid media (medium), isolate the fine particle of several microns, compared with other technology for cooking fume control, that wind-force cyclone has is simple in structure, easy for installation, strong adaptability, continuously reliable, cost is low, efficiency is high, easy care, is easy to realize automatic control etc.
The factor that affects cyclone purifying property mainly comprises structure and operation two aspects.
Structure aspects has diameter and two indexs of height of cyclone.Generally, diameter is less, and radius of turn is less, and the suffered centrifugal force of smoke particle is larger, and the efficiency of fume eliminating is also just higher.But barrel diameter can not be too little, because the wall of cyclone and blast pipe are too near, can cause larger diameter particle likely to rebound central gas stream and be pulled away, thereby reducing smoke exhaust efficiency.Height aspect, it is longer that conventionally higher cyclone can make to enter smoke particle time of staying of cylindrical shell, is conducive to separate, and can makes the particle that not yet arrives blast pipe have more chance to separate from eddy flow core, reduces reentrainment, improved efficiency.
Operating aspect has viscosity and three indexs of density of import wind speed, soot gas.General inlet velocity is faster, and efficiency is higher.But too high gas speed meeting discrete particles, so in the time of the cross section of design separator, must make import wind speed keep a suitable numerical value.Experiment shows when wind speed is at 1.5m/s -1time purification efficiency the highest.The viscosity of oil smoke is larger, density is larger, and the efficiency of separation is just lower.
Wind-force cyclone separation process energy consumption and blower fan select according to being Pressure Drop, select form, the specification of wind-force cyclone and just determine import wind speed according to Pressure Drop.
Compared with prior art, beneficial effect of the present invention is to use cyclone to produce high-speed rotational, under the action of the centrifugal, oil smoke has the longer time of staying in cyclone cylinder, what can make that oil smoke, waste gas, peculiar smell get rid of is more thorough, and purification efficiency is high, is easy to clean.Simultaneously simple in structure, easy for installation, cost is low.Be 350m3/h~400m3/h selecting suitable cyclone and blower fan situation down smoke-discharging amount, when suction inlet is 800mm apart from the distance of pot and stove, purification efficiency is relatively good, can reach 85%~92%, is up to 95%.Wind-force spiral-flow type cooking fume remover has good effect for the discharge that improves catering trade kitchen fume.After operation a period of time, there is no greasy dirt on barrel, equipment has self-purification function.
