Description
Technical field
The present invention relates to a kind of vortex type demisting dehydrating unit, especially relates to go using a kind of centrifugation of vortex type structure
Except the fine drop in air-flow, while condense the invention for removing vapor（Remove fine drop and be also referred to as demisting, remove vapor
Claim dehumidifying）.
Background technology
The separation of industrial circle hanging drop is a major issue in many chemical engineering processes, rectifying, absorption,
Desorption, increase（Subtract）It is wet to wait gas（Vapour）All it is logical either using packed tower or plate column in liquid mass transfer, heat transfer unit operation
The purpose of crossing the close contact of two-phase and separating the purification for promote the transmission of alternate component, reaching liquid or gas.At these
Process is left in the gas phase of packing layer or column plate, must carry certain amount, the drop to differ in size or liquid foam secretly；Subsequent cold
But, in condensation process, the fine particle for being suspended in gas phase can also be formed；When handled thing system is more complicated, between component
Gas-phase chemical reaction may also generate the particle of smaller.It is generally necessary to will be gone out by the drop separation of air-flow entrained with, gas is also referred to as
Liquid separates（Abbreviation demisting）.
The method of demisting is many at present, and more common demister has inertia-type, baffle plate type, spiral-flow plate-type, whirlwind
Formula, gravity sedimentation type, electric separation type, fibre web formula demister etc..The operating principle of various demisters is not quite similar, point
Particle size range that Shi Yongyu be not different.
1. inertia-type demister, relatively common inertia-type demister is by the speed and direction for changing air-flow, is made
After the larger drop of the density that is carried is assembled since effect of inertia is attached in device wall, flowed back to by gravity.Inertia-type demisting
Device mainly intercepts mechanism by inertial collision and directly and reaches gas-liquid separation.This demister due to it is simple in structure,
Treating capacity is big, therefore it is widely used in the early stage of development of demister.But caused by the structure of itself, inertia
The separated liquid-drop diameter of formula demister institute energy is bigger, is not suitable for some exigent occasions.
2. baffle plate type demister, baffle plate type demister belongs to inertia-type demister, it be using drop with
What the surface of solids collided and mist is agglomerated and trapped, by many tortuous passageways in parallel, drop is in the vertical of tortuous passageway
After assembling in wall and the trap being located at complications, flow down, separated along wall.Due to drop and the collider of wall
Can be more, separative efficiency is higher, and the pressure drop of air-flow is smaller.
3. spiral-flow plate-type demister, spiral-flow plate-type demister is a kind of typically based on the gas-liquid for centrifuging principle
Separator, as soon as spiral board places circle by many by the inclined blade of a fixed angle of altitude, becomes rotation when gas passes through impeller clearance
Turn air-flow, the drop carried secretly in air-flow is projected with certain elevation angle under the action of inertia and is thrown toward outside, collect flow to it is excessive
In chute, so as to achieve the purpose that gas-liquid separation.
4. cyclone type demister mainly carries out demisting using the principle centrifuged, the gas containing drop is in a constant speed
Drop is got rid of to barrel by the effect of centrifugal force with tangentially entering cyclone separator under degree, at this moment gas-liquid separates, gas
Stream is flowed out along top center opening, and drop is then returned by the effect of top water fender.The demister of this form is used to remove
Mist efficiency is higher, and treating capacity is big, thus application is wider.But resistance drop is often larger, and need to take certain space, installation cost
With also higher.
After 5. gravitational settling demister sets enlargement, gas flow rate to reduce on gas flow, droplet is in gravity
Effect sinking, which removes, to remove.Gravitational settling demister simple structure is reliable, but bulky, and is only used for removing large scale mist
Drop.
6. electrically separated device sets high-pressure electrostatic electrode in gas flow both sides, electric field is formed, gas is flowed through from electric field,
Drop with electric charge is by electric field action, by electrode separation.Electrically separated unit efficiency is higher, can remove small scale drop, but
The dielectric constant of drop there are certain requirements.In addition, civilian occasion, high-voltage electricity possesses certain danger.
7. fibre web formula demister forms multiple large aperture strainer using fiber in certain thickness space and constructs,
Substance strainer is less efficient to droplet capture, and multiple structure can obtain any high removal rate in theory.It is actually typical fine
Silk screen separator thickness is tieed up generally in more than 100mm, 99.7% is generally higher than to the removal rate of fine drop, the pressure loss one
As in 200-1000Pa scopes.For the higher gas of fine drop content, fibre web separator resistance has usually increased
Add.If drop is unholiness, after long-time service, risk of the fibre web there is also blocking or fouling.
Above demisting technology need to reduce runner spacing or aperture, increasing for fully removing fine drop below 5 microns of diameter
Bonus point reduces from capturing unit, increase flow velocity, so resistance increase at the same time, Reynolds number, and Reynolds number forms laminar flow when being less than 2300
Entrainment, increases removal difficulty on the contrary.
The big airflow humidity saturation of general mist amount, above technology are not suitable for dehumidifying.Humidity, generally refers in meteorology
Be air humidity, it is the content of water vapor in air.Ambient liquid or solid water are not included in humidity.Not aqueous steaming
The air of gas is referred to as dry air.The dry and wet degree of air, represent containing the how many physical quantity of vapor, be known as humidity.Mesh

(32), multi-ply linear ladder array (37) are arranged, also can multiple array in parallel；Circumscribed spiral arm is vertically connected at perforate top lid and bottom
Between plate, circumscribed spiral arm inner wall 1 (9), circumscribed spiral arm inner wall 2 (10), circumscribed spiral arm inner wall 3 (11) project on bottom plate
Curve where camber line is gold helical（Gold helical is all to be rotated counterclockwise around origin in attached drawing of the present invention）, length is not shorter than M
（M >=2, M take positive integer, M=3 in attached drawing example）90 ° of circular arcs of bar（Quadrant arc）Ecto-entad is sequently connected
Camber line, two adjacent arc radius are than 1:0.618, total rotation angle is not less than 180 °, and circumscribed spiral arm inner wall is former around gold helical
Point (8) is rotated by 360 ° counterclockwise/and position obtained by N (N takes in Fibonacci sequence one, and N >=3) is built-in spiral arm outer wall 1
(14), outside built-in spiral arm outer wall 2 (15), built-in 3 (16) position of spiral arm outer wall, circumscribed spiral arm inner wall and built-in spiral arm
Wall surrounds helical curved surface passage, and curved surface passage top and bottom are closed by perforate head cover and bottom plate；It is cut in outside circumscribed spiral arm inner wall
Spiral cylinder inner wall 1（12）, built-in spiral arm outer wall and spiral cylinder inner wall 2（13）Intersecting, phase tangent line and intersecting lens stand for spiral cylinder
Face opening sideline；Spiral cylinder inner wall 1（12）180 ° of circular arc lines are projected as in bottom plate, its radius is circumscribed spiral arm inner wall 3（11）
At 0.618 times of the radius of bottom plate projection；Spiral cylinder inner wall 2（13）In the circular arc line and spiral cylinder inner wall 1 of bottom plate projection（12）
It is connected in bottom plate projection circular arc line inscribe, with built-in spiral arm outer wall 3（16）It is intersecting in bottom plate projection；Spiral cylinder is vertically connected at
Between perforate head cover and bottom plate, head cover perforate（25）Suitable for reading in spiral cylinder, perforate radius is equal to spiral cylinder inner wall 2（13）Radius,
Mouth is closed by bottom plate under spiral cylinder.Helical curved surface channel width side collar extension is vortex type construction unit air flow inlet, head cover perforate
For vortex type construction unit air stream outlet, air stream outlet sectional area is not less than air flow inlet sectional area；Multiple vortex type structure lists
Member composition parallel connected array, forms unified air-flow inflow direction and outflow direction；Parallel connected array is horizontally installed in gas channel,
Air-flow outflow direction is unified upward, air-flow inflow direction different, vortex type because of vortex type construction unit air flow inlet arrangement difference
Construction unit air flow inlet is directed toward centrally disposed array, and it is air-flow inflow direction that array center, which forms passage collar extension,；Vortex type
Construction unit air flow inlet is directed toward the array of center opposite direction arrangement, then is air-flow inflow direction around array；Vortex type structure
Unit air flow inlet is uniformly directed toward the array of side, then signified side is air-flow inflow direction.
Parallel connected array is horizontally installed in gas channel, entrance, the corresponding corresponding airflow direction in outlet；Rich in fine drop
Air-flow with vapor is advanced by parallel connected array in each vortex type construction unit mesoscale eddies；Helical curved surface passage overcurrent
The progressive constriction of section ecto-entad, air-flow velocity increase, pressure reduce；Two wall of helical curved surface passage is phase in horizontal direction
Same gold helical, gold helical has self similar characteristic, if air-flow is perfect fluid, is surrounded on horizontal plane along gold helical
Variable motion is done by the vertical line of origin, linear velocity increase, the direction of motion is surrounded constantly to be changed by the vertical line of origin, then curved surface
The horizontal streamline of passage interior air-flow is also gold helical, and the horizontal trace of single gas molecule is overlapped with horizontal streamline, overcurrent
Section horizontal line is tapered and self is similar；Gas molecule horizontal force situation is split, 90 ° every turn of helical camber line is four points
One of circumference arc, the center of circle fix, the gas molecule moved on this section of helical camber line is acted on by normal component of force and around the center of circle does speed change
Circular motion, for normal component of force to be directed toward the component of origin vertical line motoricity, normal component of force, that is, centripetal force, the center of circle is directed toward in direction, should
Centripetal force only changes the direction of linear velocity, does not change the size of linear velocity, and be directed toward origin vertical line motoricity another is tangential
Component, in the same direction with linear velocity, which does not change linear velocity direction, only linear velocity is tangentially increased, then gas
The resistance balance of molecule all directions, gas do speed change circular motion along curved surface passage and pass through；Assuming that perfect gas is air,
Fine drop is based on tiny droplet（Hereinafter referred to as droplet, because the small surface curvature of droplet is big, surface tension is big, can be considered
Sphere）, the droplet helical camber line with 90 ° every turn in the horizontal plane（Streamline）On air drag balance, droplet can be along helical
Camber line（Streamline）It is synchronized with the movement with air molecule and smooth by this section of curved surface passage, it is every that droplet normal direction is subject to air drag to be directed toward
The helical camber line center of circle for turning 90 ° is centripetal force, and droplet is made to be used as speed change circular motion by centripetal force,
Then centripetal force FTo=mV2/ R, air drag FIt is empty=(1/2)CρAirSV2 ,
FTo=FIt is empty, mV2/R=(1/2)CρAirSV2 ,
M is droplet quality, and R is droplet speed change circular motion radius, and C is coefficient of air resistance, the air drag of sphere
Coefficient is that 0.5, S is the big area of a circle of front face area, that is, droplet, and V is linear velocity, and linear velocity is identical,
Then m/R=(1/2) C ρAirS,
R= m/((1/2)CρAirS)； …… ①
Because of m=ρWaterVBall ,
Then m/S=ρWaterVBall/S=(4/3)πr3ρWater/(πr2) =(4/3)rρWater； …… ②
2. in substituting into 1.
R=m/((1/2)CρAirS),
R=m/S×1/((1/2)CρAir) =(4/3)rρWater/((1/2)CρAir),
Because of C=0.5,
Then R=(16/3) r ρWater/ρAir
So：In curved surface passage, droplet by normal direction centripetal force do speed change circular motion radius R and tangential linear velocity size without
Close, it is directly proportional to droplet radius r, it is directly proportional to the density of water, it is inversely proportional with atmospheric density；Same scale droplet does speed change circumference
Moving radius is identical, and fixed size droplet moving radius is definite value.
Assuming that two horizontal positioned peripheral curved channel radius R1＜ R, exit width is minimum and equal, and fixed size droplet is firm
Well can be by R curved surface passages, because of Bernoulli equation：P+(1/2)ρV2+ρgh=C（C is constant）, P+ (1/2) ρ V during contour flowing2
=C（C is constant）, then in desired air, if two curved surface passage pressure at two ends difference C are constant, to pressure identical point pressure difference (1/2)
ρAirV2=C ﹣ P are constant, then the size of this linear velocity V is identical, and droplet is under pressure difference in the point（That is air drag）(1/2)
CResistance coefficientρAirSV2=（C ﹣ P）SCResistance coefficient, and FTo=mV2/R；Work as R1＜ R, droplet are under pressure in curved surface path pressure difference identical point
Difference（That is air drag）For (1/2) CResistance coefficientρAirSV2It is definite value, and point FTo 1＞ FTo（mV2/R1＞ mV2/R）, i.e. R1Curved surface leads to
Droplet moves in a circle by required centripetal force F in roadTo 1More than air drag, air drag is that definite value can not increase, droplet without
Method passes through R1Curved surface passage.
Assuming that two horizontal positioned peripheral curved channel radius R2＞ R, exit width is minimum and equal, and fixed size droplet is firm
Well can be by R curved surface passages, because of Bernoulli equation：P+(1/2)ρV2+ρgh=C（C is constant）, P+ (1/2) ρ V during contour flowing2
=C（C is constant）, then in desired air, if two curved surface passage pressure at two ends difference C are constant, pressure identical point pressure difference (1/2) ρAir
V2=C ﹣ P are constant, then the size of this linear velocity V is identical, and droplet is under pressure difference in the point（That is air drag）(1/2)
CResistance coefficientρAirSV2=（C ﹣ P）SCResistance coefficient, and FTo=mV2/R；Work as R2＞ R, droplet are under pressure in curved surface path pressure difference identical point
Difference（That is air drag）For (1/2) CResistance coefficientρAirSV2It is definite value, and point FTo 1＜ FTo（mV2/R2＜ mV2/R）, i.e. R1Curved surface leads to
Droplet moves in a circle by required centripetal force F in roadTo 1Less than air drag, air drag is that definite value can not reduce, droplet without
Method passes through R1Curved surface passage.
In desired air, in and peripheral curved passage that radius is different identical in both ends pressure difference, what tiny droplet was done etc.
High speed change circular motion, the linear velocity size of pressure difference identical point is identical in passage, FAir dragFor definite value, circular motion radius R=
(16/3)rρWater/ρAir, the radius of droplet is that then its moving radius is definite value R to definite value r；When peripheral curved channel radius is more than R,
Droplet does the centripetal movement of normal direction, and moving radius is intended to R；When peripheral curved channel radius is less than R, droplet does normal direction centrifugation fortune
Dynamic, moving radius is intended to R.
It can similarly obtain：
RLiquid =(16/3)rLiquidρLiquid/ρGas
In vortex type construction unit curved surface passage, fine drop is speed change circular motion radius R by normal direction centripetal forceLiquidWith cutting
It is unrelated to linear velocity size, with fine drop radius rLiquidIt is directly proportional, it is directly proportional to the density of fine drop, with gas density into anti-
Than；Same scale fine drop does that speed change circular motion radius is identical, and fixed size fine drop moving radius is definite value.
In perfect gas, in and peripheral curved passage that radius is different identical in both ends pressure difference, what fine drop was done etc.
High speed change circular motion, the linear velocity size of pressure difference identical point is identical in passage, FAir resistanceFor definite value, speed change circular motion half
Footpath RLiquid =(16/3)rLiquidρLiquid/ρGas, the radius of fine drop is definite value rLiquidThen its moving radius is definite value RLiquid；When peripheral curved passage
Radius is more than RLiquidWhen, fine drop does the centripetal movement of normal direction, and moving radius is intended to R, then more than radius RLiquidSpeed change circumference fortune
Dynamic structure radius can be called centripetal radius；Peripheral curved channel radius is less than RLiquidWhen, fine drop does normal direction centrifugal movement, movement
Radius is intended to R, then less than radius RLiquidSpeed change circular motion structure radius can be called centrifugation radius；And RLiquidIt can be referred to as speed change circle
All moving equilibrium radiuses.Draw two horizontal rays from origin or the center of circle and pass through built-in spiral arm outer wall and circumscribed spiral arm inner wall,
The circumscribed spiral arm inner wall arc length formed is more than built-in spiral arm outer wall arc length, because gross energy is definite value in runner（Exerted according to uncle
Sharp effect）, air-flow is faster than speed near built-in spiral arm outer wall arc in the speed near the circumscribed spiral arm inner wall arc, produces
The outside pressure differential of normal direction, increases centrifugal direction speed, therefore is selected in implementing and centrifuge the knot that radius does peripheral curved passage
Structure radius is more favourable.
The vortex type structure curved surface passage that the present invention designs, the projection of two inner vertical walls is using the same as the isometric gold helical arc of origin
Line, curve where two inner walls have certain angle through origin, and angle is 360 °/N（N takes in Fibonacci sequence one, and N >=3）,
Because Fibonacci number is classified as Fibonacci sequence, adjacency ratio is close to 0.618, the Huang that circumscribed spiral arm inner wall is projected in bottom plate
The outer starting point radius R of gold shell bankStarting pointBeing built gold helical arc that spiral arm outer wall projected in bottom plate, n times (n is Suo Qufei Poonas
The item of contract ordered series of numbers N, n=3 ... when n=2 when n=1 when and n >=1, N=3, N=5, N=8) golden section, its span width L（26）
=0.618n RStarting point（N=1, cut-point for built-in spiral arm outer wall in the gold helical arc that bottom plate projects endpoint to radius RStarting point's
Projection；N ＞ 1, cut-point built-in spiral arm outer wall on the gold helical arc that bottom plate projects with radius RStarting pointIt is intersecting）；It is at this
The air flow inlet of vortex type structure curved surface passage, speed change circular motion radius are less than RStarting pointTiny droplet do the centripetal movement of normal direction
Radius R can be passed throughStarting pointCurved surface passage, speed change circular motion radius are less than 0.618RStarting pointTiny droplet do the centripetal movement of normal direction
And because the turbulent air flow disturbance of inlet can also pass through.
Because of the characteristic of gold helical：From the outside to the core, 90 ° every turn of helical camber line is quadrant arc, and two is adjacent
Quadrant arc arc length is than 1:0.618, radius ratio 1:0.618, two camber line tie points correspond to the center of circle altogether on a normal,
Air-flow becomes larger to original 1.618 times (1/0.618=1.618) by tie point flow curvature, required centripetal on small circumference arc
Power is 1.618 times on big circumference arc, if it is R ' that big circumference arc radius, which is R small circumference arc radius, R '=0.618R then FTo small circumference arc=
mV2/R’=1.618mV2/R=1.618FTo big circumference arc, this keeps the tiny droplet linear velocity of speed change circular motion on big circumference arc
Size is constant, then the constant F of air dragIt is empty= (1/2)CResistance coefficientρAirSV2, FIt is empty＜ 1.618FTo big circumference arcAnd centripetal force side can not be changed
To, can not make the direction of centripetal force be directed toward small circumference arc from the center of circle where big circumference arc where the center of circle, tiny droplet is along former streamline
It is centrifuged to circumscribed spiral arm inner wall and accumulates moisture film；It is located at the tiny droplet that speed change circular motion is kept on big circumference arc
Radius is r, and formula is proved more than, and tiny droplet of the radius more than r centrifuges on big circumference arc, and radius is equal to r's
Tiny droplet is centrifuged after two arc tie points on streamline；Radius be less than r and more than 0.618r tiny droplet because
The streamline radius of speed change circular motion is partly depressed into built-in spiral arm outer wall between R and 0.618R, partly enters roundlet
All arc passages, centrifuge with next stage circumference arc tie point in small circumference arc or are connected in small circumference arc with spiral cylinder inner wall
Centrifuged at point；Tiny droplet radius of the speed change circular motion radius less than 0.618R is less than 0.618r, it moves 180 ° directly
Footpath is less than the sum of the radius of two adjacent flights camber lines 1.618R for 1.236R（Big circumference arc radius+small circumference arc radius）, it is horizontal
Centripetal movement is done in normal direction, built-in spiral arm outer wall is forced into and accumulates moisture film.Case above can also use formula R=(16/3) r
ρWater/ρAirSimplify and understand, R/r=(16/3) ρWater/ρAir, ρWaterAnd ρAirConstant, r changes with R direct proportions, and it can only be original to reduce R
The fine drop of scale can not change original state, be separated field, and the fine drop of remaining smaller scale continues to take exercises, then
Secondary reduction R then separates the tiny droplet of corresponding r again.
Circumscribed spiral arm inner wall, built-in spiral arm outer wall, the moisture film or liquid film of the enrichment of spiral cylinder inner wall in present apparatus operation
By gravity downstream to bottom plate, flowed out after bottom plate collects along air-flow opposite direction from air flow inlet bottom.
Airflow condition is more complex in practice, in curved surface passage there are gas-liquid mass transfer, temperature change, different scale liquid
There is evaporation, condensation, collision, change in shape in drop, usual air-flow contains higher humidity even over-saturation humidity, determined according to Charlie
Rule：P = P0(1+t/273), Bernoulli equation：P+(1/2)ρV2=C（C is constant）And Venturi effect：Flow section and stream
Body speed is inversely proportional, then air flow pressure reduces during vortex type construction unit runner is tapered, speed increases, temperature reduces, water
Steam condenses heat release, and the air-flow after heat is cooled down is absorbed and taken away, and completes heat exchange function, makes vortex type construction unit overall
Temperature reduces, and increases the condensing droplet of vapor, increases fine drop scale, and then strengthen centrifugal separating effect.Therefore, this dress
Put with certain dehumidification function, install liquid storing barrel, ultrasonic mist device or pressure additional and make mist device or liquid dispensing apparatus, circulation
Pump, circulator can strengthen effect on moisture extraction, make to be entered back into device as work mist after the water of present apparatus collection or liquid atomization
Interior vortex type construction unit, the mist amount increase in vortex type construction unit, the further saturation of humidity, water vapor condensation mist formation,
Fine drop in work mist, condensation newly-increased mist and air-flow is mixed and is centrifuged jointly, and heat is by air-flow after condensation separation
Take away, there is the part-structure temperature that water or liquid flow through to reduce inside device, continuous cycle operation for a period of time, water or liquid
Temperature and device internal temperature can continuously reduce, cause dehumidification by condensation effect to further enhance；Because of Charles' law P=P0
(1+t/273), Bernoulli equation P+ (1/2) ρ V2=C（C is constant）, then P0(1+t/273) =C-(1/2)ρV2, P0=
101325Pa is standard atmospheric pressure, and the kg/m3 of ρ=1.293, works as P0During=C, t=﹣ (273/2) ρ V2/ P0；Vortex type structure curved surface
Passage is horizontal positioned, and curved surface channel height H is fixed, the contour flowing of air-flow, self similar, circumscribed spiral arm inner wall 1 of gold helical
The flow section of outer starting point is often rotated by 90 ° span width L with two wall of curved surface passage1L is reduced into by golden section proportionM=
0.618ML1, because speed V and flow section area L × H are inversely proportional, height H is definite value, then V2 2﹣ V1 2= (V1/0.618M)2﹣ V1 2=
1.6182M V1 2﹣ V1 2, then temperature difference t2- t1=﹣ (273/2) ρ（1.6182M V1 2﹣ V1 2）/P0, M is to turn over 90 ° of number, and
Circumscribed spiral arm inner wall bottom plate projection gold helical camber line bar number, as M=3, t2- t1=﹣ (273/2) 1.293
（1.6186 V1 2﹣ V1 2）/ 101325=﹣ 0.0295V1 2℃（Negative represents temperature reduction, and wind speed is faster, and the temperature difference is bigger）If use flow
The centrifugal blower certain driving air-flow of 100m3/h, vortex type construction unit inlet velocity are 2m/s, and the specific heat of air is 1030J/
(kg·℃）, while mist is made with water circulation, the specific heat of water is (kg DEG C of 4200J/）, then the reducible temperature of per kilogram water per hour
Degree=atmospheric density × air quantity × air specific heat/water specific heat × temperature difference==1.293 × 100 × 1030/4200 × 0.0295 × 22
3.74 DEG C of=﹣；As M=1, t2- t1=﹣ 0.0046V1 2DEG C, 0.58 DEG C of the reducible temperature=﹣ of per kilogram water per hour；When M=2
When, t2- t1=﹣ 0.0119V1 2DEG C, 1.51 DEG C of the reducible temperature=﹣ of per kilogram water per hour.Increase the gold of circumscribed spiral arm
Helical arc line number can substantially increase cooling-down effect, improve dehumidification efficiency, and long-play produces tired in certain space
Add effect on moisture extraction more preferable, be more suitable for the limited civilian place of moisture.
Reynolds number physically represents inertia force and the ratio of viscous force magnitude, belongs to tangent vector, technical side of the present invention
Case is to change the direction of motion of target fluid by varying the structure in horizontal flow field, so as to fulfill gas-liquid separation, belongs to change
Normal vector, normal vector and tangent vector are vertical, and for the fine drop in present apparatus air-flow, gas-flow resistance is unable to maintain that radius is less than
The speed change circular motion of equilibrium radius, normal direction Impact direction change, and normal velocity is zero when changing normal direction force direction, from inertia
Power and viscous force influence, so without considering Reynolds number；And target fluid by normal force change side rearward away from the center of circle, although centrifugation
