Description
Technical field
The present invention relates to a kind of novel gas-liquid separator, primary using a kind of scroll isolating construction is especially related to
Exert the invention that sharp effect realizes gas-liquid separation.
Background technology
Gas-liquid separation device is a kind of common chemical industry equipment, be used for chemical reactor tower top, boiler or evaporator top,
Environmental protection equipment, for separating the drop in gas.Current existing gas-liquid separation device by operation principle can be divided into gravitational settling,
Inertial separation, cyclonic separation, electrically separated, filtering, fibre web separate six kinds.
Gravity settling separation device sets enlargement on gas flow, and after gas flow rate reduction, drop is made in gravity
Use lower sedimentation separation.Gravity settling separation device simple structure is reliable, but bulky, and can be only used for the separation of large scale liquid
Drop.
Inertial separator sets baffle plate or corrugated sheet on gas flow, and gas is obstructed by baffle plate or corrugated sheet, drastically
Change flow direction, drop is less than air-flow change in travel direction, impinges upon baffle plate or waveform because of effect of inertia, change in travel direction
On plate, so as to realize separation.Inertial separator simple structure, pressure loss is relatively small, but is equally only used for point
From large scale drop.
Gas is introduced tangentially into cylinder by cyclone separator, and gas rotates at a high speed within the barrel, and drop is because of centrifugation
Effect is got rid of to cylinder inner wall by air-flow and realizes separation.Cyclone separator small volume, the pressure loss is medium, can separate medium
The drop of yardstick, but need higher gas initial flow rate.In addition cyclone separator diameter is unsuitable excessive, larger in treating capacity
Occasion, can only be worked by the way of one group of multiple minor diameter cyclone separator is in parallel, it is necessary to larger I＆M
Space.
Electrically separated device sets high-pressure electrostatic electrode in gas flow both sides, forms electric field, and gas flows through from electric field, band
There is the drop of electric charge by electric field action, by electrode separation.Electrically separated unit efficiency is higher, can remove small yardstick drop, but right
The dielectric constant of drop there are certain requirements.In addition, civilian occasion, high-tension electricity possesses certain danger.
Filtering separation device sets filter screen to remove drop, filter screen small volume in gas flow, and it is big to remove all
Drop in filter screen effective aperture.But high-precision filter screen resistance is larger, and it is easy to block, practical value is smaller.
Fibre web separator forms multiple large aperture filter screen using fiber in certain thickness space and constructed, substance
Filter screen is less efficient to droplet capture, and multiple structure can obtain any high clearance in theory.Actually typical filament
Net separator thickness is general in more than 100mm, is generally higher than 99.7% to the clearance of fine drop, the pressure loss typically exists
200-1000Pa scopes.For the higher gas of fine drop content, fibre web separator resistance generally increased.
If drop is unholiness, after long-term use, there is also the risk of blocking or fouling for fibre web.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art there is provided a kind of weight is small, pressure drop is low, volume compact, can fill
Divide the gas-liquid separation device for removing drop.
The technical solution adopted in the present invention is：The present apparatus is by annulus top cover, circular bottom plate and one group of scroll separate sheet
Constitute；Annulus top cover overall diameter and circular bottom plate diameter are equal, and annulus top cover is coaxial with the circular bottom plate center of circle, plate face is parallel；Circle
One group of scroll separate sheet is vertically arranged between ring top cover and circular bottom plate, this group of scroll separate sheet is equal along annulus top cover annulus
Even rotation arrangement, orientation is identical（Counterclockwise, clockwise, it is contemplated that the earth is from the influence of autobiography angular force, ground
The ball Northern Hemisphere is more suitable for counterclockwise, the Southern Hemisphere is more suitable for clockwise）, each helical origin overlaps with the center of circle, height
It is upper to be connected below with annulus top cover and circular bottom plate for distance between top cover and bottom plate；Scroll separate sheet section is M adjacent
Equiangular spiral arm（M takes >=2 integer）, angularly 90 °, total angle of rotation degree is M × 90 °（That is gold helical）, inside and outside adjacent two
Arm arc length ratio is 0.618：1；Annulus top cover exradius is set to R, and then inner circle radius is（1-0.618）×0.618n-2×R；Helical
Shape separate sheet piece number N（N takes >=3 integer）, the angle of two neighboring scroll separate sheet is 360 °/N；Present apparatus cross section
For the concentric equiangular spiral arm of M layers of annular array, the radius of outermost first layer equiangular spiral arm is ((0.6182+1)/2)½R is
0.831R, the radius of second layer equiangular spiral arm is 0.6182-1((0.6182+1)/2)½R, successively inwardly, then M layers of radius are
0.618M-1((0.6182+1)/2)½R；The cavity that annulus top cover air stream outlet is formed to the view field of circular bottom plate converges for air-flow
Ji Qu；Two panels adjacent flights shape separate sheet surrounds what two panels scroll separate sheet in curved surface passage, curved surface passage was projected to axle center
Non- overlapping region is gas-liquid separation zone, and N piece helical separate sheets form N number of gas-liquid separation zone and arranged around air-flow pooling zone, composition
One group of gas-liquid separation zone of the present apparatus is scroll isolating construction, makes to contain liquid through periphery pressurization or by air inducing above air-flow pooling zone
The air-flow of drop enters the present apparatus, and air-flow is advanced past gas-liquid separation zone along curved surface channel spiral, gas-liquid separation zone inwardly gradually it is curved gradually
Contracting, radius diminishes, and curvature change is big, and sectional area diminishes, and air-flow is constantly accelerated, and drop is thrown to curved surface channel outer wall, completes gas-liquid
Separation；Air-flow after separation flows out through air-flow pooling zone along annulus top cover air stream outlet, and drop collects on curved surface channel outer wall
Cheng Liu, liquid stream is collected by gravity and stream pressure collective effect to channel bottom and circular bottom plate center, and accumulation certain altitude is anti-
Flowed out to along airflow inlet, or leakage hole outflow is separately opened in circular bottom plate.
Gas-liquid separation zone separation angle is the difference of scroll separate sheet total angle of rotation degree and two separate sheet angles（M × 90 ° ﹣
360°/N）, the equiangular spiral arm number of plies is more, and total angle of rotation degree is bigger, and the more separation angles of separate sheet number are closer to total angle of rotation degree point
Digression degree is bigger, and separation angle is bigger, and curvature of curved surface is bigger, and separating effect is better；Separate sheet number is more, and curved surface number of channels is got over
Many, single channel cross-sectional area is smaller, and separating effect is better；The smaller curvature of curved surface of separate sheet radius is bigger, and separating effect is better；Point
Smaller from piece spacing, single channel cross-sectional area is smaller, and separating effect is better；For example：2 layers of helical arm, 3 helical separate sheets always turn
180 ° of separation angles of angle are 60 °, and 2 layers of 5, helical arm, 180 ° of helical separate sheet total angle of rotation degree separation angle are 108 °, 2 layers of spiral shell
8, line arm, 180 ° of helical separate sheet total angle of rotation degree separation angle is 135 °, 2 layers of helical arm, 13 helical separate sheet total angle of rotation degree
180 ° of separation angles are 152 °；3 layers of 3, helical arm, 270 ° of helical separate sheet total angle of rotation degree separation angle are 150 °, 4 helical arm layers
3 helical separate sheet total angle of rotation degree, 360 ° of separation angles are 240 ° etc.；Set according to Rational Parameters such as air-flow velocity, pressure, flows
Put the helical arm number of plies（That is scroll separate sheet total angle of rotation degree）, scroll separate sheet piece number, separate sheet spacing, height and radius can
To obtain good separating effect.
Air-flow containing drop from gas-liquid separation zone pass through, single gas-liquid separation zone by scroll separate sheet inwall, outer wall and
Two panels scroll separate sheet projects space within the gas-liquid separation zone outer edge to be formed, the inside line to the center of circle and surrounded, both sides wire clamp
Angle（360 °/N of M × 90 ° ﹣）For separation angle, closed up and down by annulus top cover and circular bottom plate, gas-liquid separation zone lateral wall（With
Scroll separate sheet inwall intersection）Always compare madial wall（With scroll separate sheet outer wall intersection）Long (i.e. lateral wall
Sweep is more than madial wall sweep), direction from inlet to outlet, the radius curvature that diminishes becomes big, and section is gradually small, air-flow
Pressure and speed be continually changing, in turbulent condition；On any one place's airflow direction, air-flow produces Bernoulli effect, i.e.,
Outside flow velocity is big, pressure is small, and inner side flow velocity is small, pressure big, therefore outside pressure differential is formed inside and outside gas-liquid separation zone, bent
Face passage curvature is progressive to become big, and outside flow velocity is bigger, and pressure differential is bigger, and drop is accelerated to gas-liquid separation zone by outward pressure effect
Lateral wall is moved.On any one place's airflow direction, air-flow is influenceed to move along a curved path by channel shape, and the inertia force of drop is gentle
Flow drag effect produce centripetal force, the velocity balance of drop relative wind in inertia force gentle flow resistance dynamic balance, drop along
Moved with air-flow to the center of circle gas-liquid separation zone；Centripetal force weakens when the inertia force of drop is more than gas-flow resistance, and centrifugal phenomenon shows,
Drop is moved to away from center of circle direction；Air-flow by when gas-liquid separation zone diminish around center of circle direction sectional area, while produce text
Effect and Bernoulli effect, i.e. sectional area diminish in mound, flow velocity increase, and pressure reduces, therefore stream pressure reduction is that resistance subtracts
Small, the inertia force of drop is more than gas-flow resistance, and centripetal force weakens, and centrifugal phenomenon enhancing, drop accelerates on the outside of gas-liquid separation zone
Wall is moved.Drop in gas-liquid separation zone persistently by outward pressure and inertia force while act on, it is accelerated to be thrown to gas-liquid point
From area's lateral wall, gas-liquid separation is completed.
Bernoulli effect（That is boundary layer skin effect）Reflect the relation of rate of flow of fluid and pressure：The flow velocity of fluid is got over
Greatly, pressure is smaller；The flow velocity of fluid is smaller, and pressure is bigger；Bernoulli equation：p+1/2ρv2+ ρ gh=constant；Venturi effect is anti-
When should be by the flow section of diminution, there is the phenomenon of flow velocity increase in fluid, and its flow velocity is inversely proportional with flow section.Equiangular spiral
Shape curved surface channel resistance is small, saves energy consumption, many natural phenomenas are all equiangular spirals, such as tropical cyclone, galaxy cantilever, Xiang
Sunflower disk etc., gold helical is one kind of equiangular spiral.
Apparatus of the present invention are simple in construction, and air-flow enters from periphery, constrain and rotated to middle cadion-acceleration through scroll separate sheet group,
Gas-liquid separation is completed in rotary course, the air-flow after separation is exported along center updraft to flow out, after the liquid after separation collects
From bottom outer or bottom centre's leakage hole outflow；What the gas-liquid separation zone inside device was shaped as centripetal bending and constantly shunk
Scroll, air-flow by when pressure and speed be continually changing, in turbulent condition, flow velocity is constantly accelerated, and continuously generates Bai Nu
Drop in sharp effect and Venturi effect, air-flow is always less than inertia force and outward pressure along the resistance that gas-liquid separation zone is subject to
Sum, drop is accelerated to be thrown to gas-liquid separation zone lateral wall, completes gas-liquid separation；Device whole height, diameter can be with internal junctions
Structure change adjustment, the internal helical arm number of plies（That is scroll separate sheet total angle of rotation degree）, scroll separate sheet spacing, scroll point
It can be adjusted from piece piece number, height and radius with application parameter.
In summary, flow velocity can be increased by reducing curved surface channel cross-sectional area, and increase curved surface passage curvature can increase passage
Interior outside pressure is poor, so as to improve gas-liquid separation efficiency, then single curved surface channel cross-section can be reduced by reducing separate sheet spacing
Product；Increase separate sheet quantity can increase curved surface number of channels, reduce single curved surface channel cross-sectional area, make separation angle closer
In curved surface passage total angle of rotation degree；Passage curvature can be increased by reducing the angle arm radiuses such as separate sheet helical；Increase the continuous spiral shell of separate sheet
The angle arm such as line number of plies can increase curved surface passage total angle of rotation degree and improve curved surface passage curvature.Above method can improve gas-liquid
Separative efficiency, using the restrictive conditions such as appropriate to the occasion combination gas flow rate, gas pressure, gas flow, working space integrate use with
Upper method.
The curved surface passage of this programme design also can be arranged in parallel used in parallel, but is compared with circular arrangement, more occupies sky
Between.
The beneficial effects of the invention are as follows can reduce volume, the pressure drop of gas-liquid separation device, improve removal efficiency, reduce
