Description
Technical field：
The present invention relates to a kind of kitchen appliance, particularly a kind of lampblack absorber.
Background technology：
Traditional lampblack absorber uses centrifugal fan.The mode of separation oil smoke is divided using suction is got rid of
From the separation of, whirlpool, condensation separation.Centrifugal blower is the principle that potential energy is converted to according to kinetic energy,
Impeller using high speed rotation accelerates gas, then slows down in Blower Housing, changes flow direction,
Kinetic energy is set to be converted into pressure energy.After gas discharge in impeller, the pressure in impeller be less than into
Wind overpressure, new gas intake impeller in the presence of pressure differential, and constantly circulate.Oil
Cigarette separates plate technique, turnover collision at a high speed under numerous vortices effect of the oil smoke in plate, is separated
Flue gas afterwards enters cigarette machine air channel around separating plate, and soot gas are carried out by the rotation of turbine
Secondary oil smoke separation, oil smoke is subject to centrifugal forces, the aggegation on cavity, cold plate
Into oil droplet, lubricating cup, theoretical fume purifying rate 90% are collected into by oil circuit.Due to by impeller
The mechanical movement exhaust of rotation, cause machine high energy consumption, overall volume are larger, internal greasy dirt is big,
Not easy to clean, the steam for cleaning impeller washes technology, also inconvenient in actual use.
Axial flow blower, purposes is very extensive, be exactly with the equidirectional air-flow in the axial direction of fan blade,
Such as electric fan, outdoor machine of air-conditioner fan is exactly that axle stream mode runs blower fan.Why " axle stream is referred to as
Formula ", it is because gas flows parallel to fan shaft.When the impeller is rotated, gas is from air inlet
Axially into impeller, raise the energy of gas by the pushing of impeller blade, Ran Houliu
Enter stator.Guide vane is changed into axial flowing by air-flow is deflected, while introduces gas into diffuser pipe,
Gas kinetic energy is further converted into pressure energy, is finally introducing working line.Axial fan
Cross section is generally wing section.Blade can also be surrounded its longitudinal axis and be rotated with fixed position.
The angle or blade pitgh of blade and air-flow can be with non-adjustable or adjustable.Change blade angle or
Spacing is one of main advantage of axial fan.Vanelets pitch angles produce relatively low stream
Amount, and higher flow can then be produced by increasing spacing.Advanced axial fan can be in blower fan
Change blade pitgh (this is rather similar to lifting airscrew) during operating, so as to correspondingly change stream
Amount.This is referred to as adjusting rotor blade (VP) axial fan.Mixed flow (oblique flow) blower fan is by impeller meridian
Surface current line is gained the name with axis oblique, is one between centrifugal fan and axial fan
Kind form, it is a kind of blower fan for having both centrifugation and propeller fan features concurrently.Existing axial-flow type
Blower fan big flow coefficient, efficient advantage and simple in construction, have centrifugal fan high pressure again
The advantages of force coefficient, wide working range, there is high efficiency, the characteristic of low noise.And pneumatic property
Can be close with wing blades, and machine number it is small, it is in light weight, return torque force it is small, it is in light weight,
Small volume, low-power, cost are low, installing space is small, support two-shipper series, parallel, removable
Motor is unloaded, is readily cleaned and maintains.Due to diagonal flow fan air-flow from axially gradually become oblique
Into flowing to, slowly become radially from impeller outlet is out rear.Therefore, impeller internal flowing is equal
Even, round and smooth, eddy current loss is few.From the point of view of hydrodynamics, rational import and export blade angle
Both it can guarantee that shock at entry loss was small, and can ensures that leaving energy is evenly distributed, and can reduce spiral case
Lost caused by self-energy redistribution.Also ensure and flow to interior air-flow progressively round and smooth mistake
Degree.Because blade percussion loss is few, air-flow relative velocity can be improved, therefore, the anti-work of impeller
Expenditure is big.The more reactions of static pressure liter are bigger in impeller, and efficiency is higher.Inlet calibre is small,
Internal and outernal leakage is few, and volumetric efficiency is high.Static pressure blast 280Pa, the electricity of traditional centrifugal fan
Acc power 200W-250W, exhaust air rate 15m3/min；And the existing type of oblique flow booster fan 150
(tube diameter 150mm), power of motor 30W-54W, exhaust air rate 9m3/min；200 types,
Power of motor 128W, exhaust air rate 14m3/ min, blast 352Pa.Power of motor only have tradition from
The 15%-50% of core type motor.Increased with adjusting rotor blade (VP) axial fan, mixed flow (oblique flow)
Pressure fan can also carry speed regulating control plate, adjust rotating speed, power adjustable, more intelligently.Also
Can be by the way of in parallel, series connection, raising efficiency.
The impeller of traditional lampblack absorber is the rotary part of blower fan, energy transmission is risen decisive
Effect.Because volume is larger, in parallel, series connection can cause volume larger.Impeller structure parameter
Change such as：The number of blade and arrangement form, the import and export established angle of blade, vane airfoil profile and
Mean camber line shape etc. is very big to performance impact.Air-flow is held mainly be axially moved before the impeller,
Blow to middle rear end, lead in effective air-out of the primarily radial flowing in middle rear end, and impeller
Road.The main purpose of design：It is to improve air output, increases effective air-out passage width, improves
Blower fan exhaust efficiency.Exhaust is also taken into account when separating oil smoke.Reality is also by manufacturing process, whirlpool
Wander about as a refugee mental and physical efforts, blast, wind speed, secondary speed, blade angle, oil smoke density, concentration, work
Shake, the influence of noise it is very big.Flabellum central fixed shaft position, flow efficiency to air-flow,
Pneumatic noise, vortex can also have an impact.The impeller of blower fan is also its critical component, improves blower fan
Efficiency, improve its performance, the design of impeller just seems of crucial importance, directly influences blower fan
Performance.
Traditional lampblack absorber technical principle of itself determines that design limit grease separating degree is
92%, aldehyde stupid to other pernicious gases, PM2.5,0.01 micron of fine dust particles and bacterium
It can not separate, be directly discharged in air, endanger environment as undressed vehicle exhaust.
It is the foundation that cooking can manufacture PM2.5.And mixed flow (diagonal flow type) blower fan is used, separate oil smoke
Work is completed by the plasma electric field of flabellum front end, can not only handle oil smoke, additionally it is possible to catch small
Grain dust and bacterium in 0.01 micron, the separating degree of oil smoke is more than 95%, more cleaning,
It is more efficient.Volume, the surface area size of plasma electric field electrostatic blade, can influence ionizing efficiency,
Equipment volume, equipment power dissipation, use cost.As far as possible more blades is filled in as far as possible small space
The space that the blade group of group, hemispherical or Gothic takes is small, and the size for ionizing piece can be with
The ratio done is rectangular big.It is smoke discharging pipe, quiet after plasma electric field electrostatic blade group
Air-flow can be led directly between electric blade group, oil smoke, and no oil fume separation plate blocks, be not vortexed,
Will not produce wind make an uproar, be vented it is more smooth.
Discharged using high-pressure electrostatic plate and produce the molecule knot that low temperature plasma changes oil particles
Structure, and charged particle is adsorbed by low-field electrode, and odor molecules chain can be effectively destroyed, thoroughly
Oil removing peculiar smell is removed, fume purifying rate is high, noise is low.Collect smoke evacuation, purification, taste removal, sterilization,
The multiple functions such as noise elimination one.Present lampblack absorber has the function of possessing anion, is all to use
Small-sized anion generator module, there is certain purification air.Because power is low and new
Type plasma electric compares from piece lampblack absorber, the power of purification, less efficient.Having inside flue can
With the valve of folding, returning is mainly prevented.The tune of indoor and outdoors circulation can not be realized
Save function.
The principle of Venturi effect is then when blowing air over obstacle, in the leeward of obstacle
Near ports air pressure is relatively low above face, so as to produce suction-operated and cause the stream of air
It is dynamic.The principle of Venturi tube is in fact very simple, it be exactly air-flow from the coarse to fine, to accelerate gas
Flow velocity, gas is set to form a region of no pressure in the rear side trunnion of venturi outlet.This region of no pressure
Certain suction-operated can be produced.The air inlet of oblique flow booster fan is more than motor diameter, outlet
The mouth of pipe makes collapsible tube, and afterbody is anemostat.
The zigzag exhaust on edge after the Rolls Royce turbofan engine of Boeing B-787 passenger planes
Mouthful, it is referred to as sawtooth pattern nozzle, the noise given birth to when being for reducing engine exhaust.So
Jagged nozzle, the hot-air for being advantageous to engine discharge mix with the cold air outside machine, so as to
Reduce the high noisy of engine discharge waste gas.Zigzag trailing edge nozzle is applied on aviation jet pipe
Noise reduction technology purpose, have noise reduction is obvious, thrust loss is small, processing it is simple many advantages, such as.
Traditional lampblack absorber, oil smoke is after wind wheel, no matter how separation rate is all directly arranged
Put flue into.Ultimately result in oil smoke and be largely deposited on cigarette machine wind wheel, inwall, blast pipe, flue
In.And plasma electric is used first to carry out primary ionization point to oil gas from the lampblack absorber of the filtering of piece
Solution, if oil smoke is big, concentration is high, waste gas also needs to circulate again.Waste gas recycles (Exhaust
Gas Recirculation, abbreviation EGR) device, to being sent out well on internal combustion engine
Exhibition.EGR efficiency is 5%-20%, can be adjusted by EGR valve, and waste gas discharge reduces 50%-70%.
Egr system is typically by ECU (ECU), EGR valve (having valve opening sensor), biography
Sensor, vacuum solenoid, pipeline etc. are formed.The part that lampblack absorber is discharged is given up using this principle
Gas is transmitted back to inlet manifold, and is again introduced into together with incoming mixture in front of ionization piece.Due to
Contain substantial amounts of negative ion in waste gas, so as to strengthen plasma electric from effect, without
Increase power of the plasma electric from piece, there is energy-conservation.It is of course also possible to use increase electricity
Preferably ionization effect is realized from the mode of piece power.Raising ER EGR Rate can make total
Exhaust gas flow is reduced, therefore pollutant output quantity total in waste gas discharge relative will be reduced.
Booster includes engine driven supercharging and turbocharging.Engine driven supercharging is usually to utilize belt
Crank pulley is connected, the torsion of crankshaft operation is driven into booster indirectly, reaches supercharging purpose.
Different according to construction, there is numerous species, including vane type, Lu Shi, Wen Keer in engine driven supercharging
Etc. pattern, and bent axle coordinates piston movement to be also a kind of engine driven supercharging.Motor passes through during work
Shaft joint directly drives bent axle, drivening rod, crosshead and piston rod, makes piston in compressor
Cylinder in it is reciprocating, complete suction, compression, discharge etc. process.The machine is double acting
Compressor, i.e. piston move downward upwards is free aspiration to enter, compress and discharge.Standard machinery
The type of booster has three kinds：Shandong formula (Roots), double-screw type and centrifugal.They main
Difference is that the mode for drawing air into motor intake manifold is different.Shandong formula and double-screw type machine
Tool booster uses different types of engagement flange, and centrifugal mechanical supercharger is inhaled using impeller
Enter air.Screw compressor is a kind of positive displacement compressor of revolution at a high speed, is contained by a pair
The rotor for having spiral alveolar is intermeshed, and causes the change of volume to carry out gas compression, except two
Outside the screw rotor of individual revolution at a high speed, without other moving components, Rotary Compressor is overcome
(such as centrifugal compressor) and reciprocating compressor (such as piston compressor) respective deficiency,
With such as small volume, in light weight, smooth running, few easy workout part, efficiency high, single-stage pressure ratio it is big,
The advantages that energy step-less adjustment, developed rapidly and applied.Also single-screw air compresses
Machine, also known as single-screw air compressor, Worm type air compressor machine, worm compressor etc..Single-screw is empty
Air compressor is made up of the planar gaterotors of a cylindrical screw rod and two balanced configurations and nibbled
Pair is closed, in main case.The screw channel of screw rod, the inwall of main case, the flank of tooth three of star-wheel
The space surrounded constitutes the swept volume of compressor.Motor directly drives screw shaft to rotate, spiral shell
Bar drives star-wheel to rotate again.Gas is entered in helicla flute by the air entry on main frame, after compression
Discharged again by the steam vent on main case.Spray hole is also provided with main case, lubricating oil is sprayed into
In swept volume, play a part of sealing, cooling and lubrication.Turbocharging is the height to waste gas
Effect utilizes, and increases air inflow by compressed air.Rushed using the waste gas inertia of lampblack absorber discharge
Power promotes the turbine in turbine room, and turbine drives coaxial impeller again, impeller force feed is by air
The air that cleaner pipeline is sent, it is allowed to supercharging and enters cylinder.When motor speed is speeded, waste gas
The velocity of discharge is also synchronously speeded with secondary speed, and impeller just compresses more air and enters air inlet
Road.Here it is us, usually most common turbo charging installation, booster are actually a kind of empty
Air compressor, 40%-100% power can be increased by installing the device of exhaust-driven turbo-charger exhaust-gas turbo charger additional.
Lampblack absorber will not only have powerful power, the discharge of high efficiency and clean enough.
To realize more efficient working condition, it is necessary to meet under each working condition of blower fan for air inflow
Demand.This requires each part to meet by " variable " under different operating modes
Condition.Core is exactly the guide vane in adjustable vortex section, and one is added on the outside of blade
Ring can be controlled the guide vane of angle by electronic system, and the relative position of guide vane is fixed
, but blade angle can adjust, when system works, waste gas can be sent along guide vane
To impeller blade, by adjusting blade angle, the flow of the gas of impeller blade is flowed through in control
And flow velocity, so as to control the rotating speed of fan.When slow-speed of revolution pressure at expulsion is relatively low, water conservancy diversion leaf
The angle that piece is opened is smaller.According to fluid mechanics principle, the air velocity now imported at impeller
It will accelerate, increase the pressure at impeller, so as to be easier to promote wheel rotation, mitigate
The sluggish phenomenon of impeller, response time and acceleration capacity when also improving the impeller slow-speed of revolution.And
In the lifting and the increase of pressure at expulsion with rotating speed, blade also gradually increases the angle of opening,
Under full load state, blade then keeps the state of standard-sized sheet, reduces exhaust back pressure, so as to reach
To the pressurized effect of general big fan.Changing blade angle can be carried out effectively to the rotating speed of fan
Control.By variable-area guide vane, cigarette owner's air intake duct, and oblique flow wind can be also used for
Machine is all to increase air inflow in a manner of adjusting airway pressure.
Main exhaust surrounding opens waste gas pod apertures, can open 1 or number of perforations.From
The inlet manifold of the waste gas of Venturi tube airway branch, for the pressure of balanced air flue, Venturi tube
4 close 1 pipeline, are the front, rear, left and right on pipe wall circumference, open 4 holes.With one
Control valve is drawn out to after the placed in series that bar pipeline draws 4 holes, due to 4 common conjunctions 1
The discharge duct exhaust pathway of arrangement is shorter, and the length difference, gas pressure in each bar pipeline are not
Together, can interfere with each other, the gas having been drained off will be again introduced into master by other suction inlet suck-backs
Discharge duct, influence exhaust efficiency.This mode is feasible, it is also possible to improve.In pipeline
Air inlet, contraction section, endpiece install more circuits, or the mode of air flue perforate are simplified into 1
Individual hole, 2 holes, either open 3 holes or open it is more porous, but due to length of pipe is short,
The problem of pressure difference, still it not can solve the problem of exhaust gas recirculation.
The double scroll technologies of single turbine can be simply interpreted as at the exhaust gas entrance of typical turbine
An exhaust steam passage is increased, the difference is that turbine is by the exhaust gas driven of two passages.It is exactly
By the air-flow of a turbocharger by being divided into two strands of air-flows during scroll, per share air-flow is responsible for
2 manifolds.Reduce the situation that exhaust pulses interfere.Similar technical principle also has single
Double scrolls of turbine list scroll, double turbine list scrolls, double turbines etc. be all increase or reduce turbine,
The combination of the quantity of scroll.
Cigarette machine shell integrated form pipeline.It is empty using prefabricated pipeline by optimizing shelling machine
The exhaust manifold of chamber, it is possible to reduce length of pipe.Shorten between blast pipe and turbocharger
Distance, turbine is allowed to respond rapider, exhaust efficiency is higher.It can be also used for the various of lampblack absorber
Pipeline, circuit, cigarette machine inwall oil smoke deposition is very big, now using nothing on condensation chamber, cold plate
Guiding gutter, greasy dirt attachment is more, guides profit to rapidly flow toward oil box by oil guide groove, can be with
It is quick to collect profit, reduce the greasy deposits of cigarette machine inwall.Integrated form pipeline also includes inside and outside
Air circulation duct, air inlet, exhaust manifold, egr conduit, oil guide groove, conduit
Road.
