Abstract
An aerodynamic agglomerator ( 10 ) promotes mixing and agglomeration of pollutant particles in a gas stream, to facilitate the subsequent removal of the particles from the gas stream. The agglomerator ( 10 ) is mounted in a duct ( 11 ) through which the gas stream flows. The agglomerator ( 10 ) comprises a plurality of parallel plates ( 12 ) which extend in the overall direction of flow of the gas stream, and are spaced transversely across the width of the duct ( 11 ) to divide the duct into multiple parallel passages. The duct ( 11 ) is configured and/or has formations therein for creating large scale turbulence in the gas stream upstream of the passages. A vane assembly ( 13 ) is provided in each passage for generating a zone of small scale turbulence of such size and/or intensity that the pollutant particles are entrained in the turbulence. Each vane assembly ( 13 ) is located centrally relative to its respective passage and comprises a plurality of sharp-edged vanes ( 15 ) spaced successively in the overall direction of flow of the gas stream. The large scale turbulence in the substreams causes each substream to pass through the zone of small scale turbulence in its respective passage so that particles therein are subjected to the small scale turbulence.
Description
Technical field
The present invention relates generally to and is used for fluid-mixing stream so that the method and apparatus of particles coalesce.The present invention more specifically but not only, is applicable to the pollution control of removing contaminate particulate from air-flow.
A preferred embodiment of the present invention relates to the aerodynamics particles coalesce, wherein uses the turbulent flow of particle scale size to strengthen interaction between the particle and coalescent, is convenient to thus further to filter or other removes particle from air stream operation.
The application requires the priority of Australian patent application No.2003902014 and No.2004900593 number, and the disclosure of above-mentioned two applications is incorporated this paper into for your guidance.
Background technology
A lot of industrial process all can discharge harmful particulate in atmosphere.These particles generally include very thin sub-micron toxic compounds particle.Because these particulates can enter the respiratory system of human body, so they have caused serious harm to public health.Toxicity is added the understanding of the combined characteristic that is easy to incoming call and is impelled global government to make laws, and strict more control diameter is less than the particle of 10 microns (PM10), particularly less than the discharging of the particle of 2.5 microns (PM2.5).
Littler particulate in the airborne release also is the major influence factors of low visibility situation in the atmosphere pollution.For instance, in the coal combustion device, the flue opacity depends on the particulate part of flying dust to a great extent, because extinction coefficient peak value and light wavelength 0.1-1 micron are very approaching.
The importance of particulate control can be weighed by considering contamination particle number rather than pollutant gross weight in the primary emission.In the flying dust that once typical coal combustion process discharges, may only account for 7% of gross contamination thing less than 2 microns contamination particles, but account for 97% of total particle number.Remove all methods greater than 2 micron particles and may look very effective, because it has removed 93% polluter, but 97% contamination particle is not removed in addition, is wherein comprising the poisonous particle that more can suck.
The a variety of methods that are used for removing from air stream dust and other contamination particles have been arranged.Although these methods generally speaking all are suitable for removing bigger particle from air stream, to filtering out the particle of littler particle, especially PM2.5, effect will be very different usually for they.
A lot of groundwater pollution controls all depend on contact between each composition of particular types to promote to help removing subsequently the reaction or the interaction of relevant pollution components in the waste gas stream.Such as, the adsorbent of active carbon one class can spray into and be used to remove mercury (absorption) in the gas stream of pollution, perhaps can spray into calcium to remove sulfur dioxide (chemisorbed).In addition, particle can be agglomerated into larger particle by colliding/stick effect, and then improves the collection property of particle, perhaps, the physical characteristic of individual particle can also be changed into the physical property of agglomerate, and then is easier to collect and/or filter.
Yet,, must introduce these related substances in order to produce these interactions.For a lot of industrial pollutants in standard flue, this is very difficult owing to some reasons.Such as, reaction/interactional time range very short (0.5-1 second) usually, introduce material abundance in waste gas considerably less (with respect to a large amount of fluid stream), the size of flue is very big with respect to the contamination particle size.
In general, the industrial process exhaust gas discharged is introduced into a big conveyance conduit, described conveyance conduit is transported to some collected downstream devices (such as electrostatic precipitator, bag filter or cyclone dust collectors) equably with them, and turbulization/energy loss as few as possible.This turbulent flow produces in course of conveying, normally gas around the blade of rotation, around pipe interior support/stiffener, pass turning on a large scale that diffusion partitions and similar object thereof carry out.This turbulent flow always has the size of whole conveyance conduit, and reaches the requirement that changes the flow direction as far as possible tout court.
Similarly; when for concrete purposes; when using mixing apparatus such as the absorption of specific pollutants, these mixing apparatus can produce extensive field of turbulent flow (promptly with the width of transfer passage or highly suitable field of turbulent flow) usually, and are configured to the simple heavy curtain (curtain) that gas must pass through.
The known mixing that can also in mixing apparatus, use vortex generator to promote fluid stream.And, the extensive turbulent flow that known vortex mixer generation and transfer passage or chamber size are suitable.
No matter the pollutant that comparatively is difficult to collect in the industrial smokejack is that graininess (such as flying dust), gaseous state are (such as SO
2), vaporific (such as NO
x), or element state (such as mercury), they all have micron (that is: 10
-6M) diameter of size.Because these particle sizes are very little, they occupy very little volume ratio in whole air-flow.For instance, the particle of 1,000,000 1 μ m diameters is at 1cm
3Gas in only occupy volume (supposing that these particles all are spherical) less than 0.00005%.Even the particle of 10 μ m diameters, this ratio also just rises to 0.05%.When considering that pollutant as mercury may only account for a few millionths (ppm) of gross contamination thing, obviously with respect to granular size, the interval/distance between the pollutant that industrial flue gas is carried is very large.Therefore, the large-scale mixing, even the mixing by vortex generator also all are uncertain incidents, and efficient is very low.
In addition, the entrained particulate of fluid stream has a characteristic: if there is not enough power to make it break away from fluid stream, they can flow by streamline in fluid stream.That is to say that if the inertia force of the viscous force domination particle of fluid stream, particle will flow with fluid stream so.The turbulent flow hybrid mode of known pipeline scale is more much bigger than the amplitude of the turbulent flow of particle scale.When the angle of particle is seen, they far are not mixes, and also some is smooth-going comparatively speaking.And particle may have many times direction and changes by ducted turbulent flow or by the standard Mixed Zone time, and the scope of these changes is all too big with respect to the size of particle or scale.Therefore the particle in the fluid stream can not interact with the particle around them more or less all along identical path flows.Mixing on particle scale is seldom arranged, and therefore the particles coalesce efficient of known mixed method is very low.
Therefore, attempt to make the maximized system of collision rate that occupies the very small pollutant of very low volume ratio in total fluid stream, should produce turbulent flow on a small scale, i.e. the turbulent flow of particle scale is to obtain maximized effect.The turbulent flow of particle scale will cause particulate to move with different speed along different tracks, therefore promote interaction and coalescent.Regrettably, present design principle is not fully covered these standards of row as yet.
The purpose of this invention is to provide the fluid stream mixed method and the equipment that are used for particles coalesce, with reach improve fluid flow in the mixing or interaction of particulate and identical component or other introducings larger particle composition wherein, impel more effective particles coalesce thus or more effectively absorbed by bulky grain.
Summary of the invention
In a wide scope, the invention provides a kind of method that promotes that material mixes in the fluid stream, may further comprise the steps:
In fluid stream, produce extensive turbulent flow;
Described fluid flow point is divided into a plurality of tributaries;
In each tributary, provide a kind of member, near described member, to produce turbulent area on a small scale; And
Make each tributary pass its corresponding turbulent area on a small scale, so that it stands described small-scale turbulent flow.
On the other hand, the invention provides the equipment that promotes that material mixes in the fluid stream, comprise
The pipeline that is used for fluid stream;
Be positioned at a plurality of passages of described pipeline, described passage is used for the fluid flow point is divided into the tributary of flowing through corresponding described passage;
Be used in fluid stream, producing the device of extensive turbulent flow in the upstream of a plurality of passages; And
Be positioned at a kind of member of each passage, described member is used for producing turbulent area on a small scale near described member;
Wherein, in use, extensive turbulent flow makes the tributary in each passage pass turbulent area on a small scale.
Each member is preferably placed at the center in tributary separately, can suitably comprise a plurality of on the plane of extending along whole fluid flow direction continuously arranged root piece.Described blade should separate, also should be enough closely so that enough produce a continuous small-scale turbulent area, and blade can be installed in the framework of a general plane of the whole flow direction extension that is positioned at channel center plane and longshore current body stream.
Each blade all is elongated member usually, and this elongated member has the sharp edges part that is the inclination angle with the flow direction of described fluid stream.Blade can optionally have toothed marginal portion.
Above-mentioned coalescent equipment can comprise the parts of many parallel general plane, and described parts extend along the whole flow direction of described fluid stream, and spaced apart and described pipeline lateral cross.Described passage is defined between adjacent two flat components.Yet, be appreciated that described passage needn't form by the solid sept, also can be the imaginary passage in each tributary.
In one embodiment of the invention, described pipeline is a ventilation shaft, and described fluid stream is the waste gas stream that produces in the industrial process, and described material comprises contamination particle.In this embodiment, the present invention includes and use turbulent flow to control position, speed and the track of the contamination particle of micron in the waste gas stream or sub-micron, with improve they each other and/or and air-flow in collision probability between other particle so that be agglomerated into the particle of bigger easier removal, and/or increase them and introduce collision and interactional probability between the particle of other the bigger kind in the air-flow for removing contaminant particles.
This process comprises following basic step:
(i) the extensive turbulent flow of generation proper range makes in the waste gas stream and produces big turbulent flow;
(ii) air-flow is divided into the tributary that enters in the passage separately; And
(iii) make the tributary carry out the small-scale turbulent flow.
Term " extensive turbulent flow " and " big turbulent flow " all are meant the turbulent flow of conveyance conduit yardstick, i.e. its influence spreads all over the turbulent flow of whole pipe.
Term " on a small scale turbulent flow ", " microturbulence " and " turbulent flow of particle scale " all are meant the turbulent flow in enough small-scales, so that individual particle can be brought in the turbulent flow, and so to improve the aerodynamics of particle coalescent.This turbulent flow is confined to the zone the blade next-door neighbour usually.
Along in the small-scale turbulent region of the middle body longitudinal extension of each passage, particle is brought into fully, and stands turbulent flow usually.This turbulent flow has promoted collision and the interaction between the granule, causes coalescent between them.
The extensive turbulent flow of upstream is produced by the geometrical construction of pipeline itself usually, such as bending, branch, contraction and expansion etc.Yet, if fluid stream enough not large-scale turbulent flow when admission passage just need give fluid stream extra extensive turbulent flow by the barrier of introducing in the pipeline of passage upstream such as pillar and baffle plate.
When the fluid stream of turbulent flow was separated into tributary in the passage separately, the tributary also was subjected to this extensive turbulent flow.Particle in each tributary is by its small-scale turbulent region in passage separately like this, and stands the turbulent flow of particle scale.
The use of turbulent flow is counterintuitive on a small scale.Usually wish that the pressure in the air-flow descends low as much as possible.Owing to this reason, known particle hybrid system is used extensive turbulent flow usually.Yet as the above mentioned, extensive turbulent flow efficient is very low.Turbulent flow is impelled mixing better between the particle on a small scale, but has also caused the very big pressure loss.And the present invention only the finite region in each passage used turbulent flow on a small scale, thereby pressure drop is minimized.Extensive turbulent flow in each inner fluid passage stream tributary guarantees that particle in each tributary is all by this zone and stand the mixing of particle scale.
On a small scale turbulent flow can be to utilize the blade of sharp edges and the vortex form that produces.Preferably, can utilize many little low intensive vortexs that single particulate is involved in wherein fully, make them stand turbulent flow, produce collision and interaction between the particle thus, and more effective coalescent between the particle.Can be between the particulate by coalescent formation bulky grain.Particulate can also take place coalescent with the bulky grain in the fluid stream.Can from air-flow, more easily remove this particle after coalescent with existing method subsequently.
In another embodiment, one or more bulky grains are introduced in the air-flow to remove contaminant particles.When these contaminant particles contacted with the bulky grain thing, they tended to therefore can utilize the bulky grain thing that these contaminant particles are removed from air-flow attached to reacting on the bulky grain or with it.Contaminate particulate is involved in wherein by the vortex of small-scale turbulent region, but the bulky grain in each tributary is not involved in, and perhaps indrawn degree is less.Mutual motion between the size particles has caused the collision of higher frequency between them, and more efficiently by bigger trickle (pollution) particulate of (removal) particle removal.
Preferably, can select the kinematic viscosity number by the small-scale turbulent flow of vortex generation, so that trickle contamination particle is involved in, and bigger removal particle is not involved in.Usually, the kinematic viscosity number just can guarantee that less than 1 trickle contamination particle is involved in.The kinematic viscosity number of bigger removal composition granule should be greater than 1, so that they are not involved in.In fact vortex that produces in air-flow or vortex are approximately the 10mm size.
Contaminant particles may be gas phase, liquid phase or solid phase.Bigger particle can be liquid phase or solid phase, such as drop.
Removing thing can be a kind of chemical substance, such as calcium, it can and contamination particle (such as sulfur dioxide) chemical reaction takes place generates the third compound (such as calcium sulfate).Perhaps, removing composition granule also can be by absorbing or contaminant particles is removed in absorption (mercury particle that carbon granule absorption is polluted), perhaps removes composition granule and can coalescently remove fine pollutant by what produce with pollutant collision adhesion.
For the present invention can be understood and realize better, only embodiment is described by embodiment now with reference to accompanying drawing.

The specific embodiment
Fig. 1-6 has described the coalescent equipment of a kind of according to an embodiment of the invention aerodynamics.This coalescent equipment 10 is installed in the conveyance conduit 11, and this conveyance conduit receives exhaust gas discharged stream in the industrial process usually, as shown in Figure 1.

It should be noted that this coalescent equipment 10 is first sources, that is to say, the charging of the assembly of coalescent equipment on the meaning degree or charged.
In use, the air-flow in the conveyance conduit 11 will stand extensive turbulent flow or big turbulent flow.Usually, expansion, contraction, bending, branch, baffle plate, blade, pillar or other physical features that exists usually in the industrial exhaust gas pipeline will be enough to introduce extensive turbulent flow in air-flow.For instance, be used for the baffle blades 18 of steering current direction, cause the turbulent flow of interior separation of air-flow and long distance.If yet the big turbulent flow in the air-flow can increase the big turbulent flow that agitating device provides to be needed that flows not enough in pipeline 11 when air-flow arrives coalescent equipment 10.For instance, do not have turbulent flow to cause the conveyance conduit of member very long (be such as duct length pipe diameter 4 times), so just should in pipeline, increase mobile agitating device if directly be in coalescent equipment 10 the place aheads.
A suitable mobile agitating device is the pipe 9 (perhaps also can select 100mm * 100mm angle section) that row are installed in the 100mm diameter in the pipeline 11, so that their full extension are passed air-flow to produce extensive turbulent flow.Such pipe 9 should be installed as with pipeline 11 and laterally be no more than 1m apart.If do not have enough extensive turbulent flows in coalescent equipment 10 dead aheads, can adopt many various physical features in air-flow, to introduce big turbulent flow in coalescent equipment 10 upstreams, this it will be apparent to those skilled in the art that.
When air-flow was crossed coalescent equipment 10, it was separated into a plurality of tributaries, and the passage separately between the adjacent panels 13 is flow through in described tributary.In the tributary, also continue to remain with the big turbulent flow of air-flow, make that the particle in each tributary passes through the interior blade assembly 13 of respective channel, shown in the streamline among Fig. 5.The turbulent flow of extensive in the tributary, long distance is guaranteed basically all blade assembly 13 of tributary stream by being positioned at passage central authorities in the passage.
When blade assembly 13 is passed through in a tributary, will stand turbulent flow or microturbulence on a small scale, shown in the dash area among Fig. 6 19.Angled blade 15 can produce the turbulent flow of particle scale, impels collision and interaction between the particle in each channel interior tributary, has improved the coalescent of particle.Because formed turbulent flow on a small scale near blade 11, the particle in the tributary is involved in the turbulent flow, cause collision and adhere to probability obviously increasing.Adhesion process may be a kind of surface action (such as absorption, chemisorbed or absorption process), a kind of molecular action (result of van der waals force effect) or a kind of wet processes (result of mist and other droplet or solid particle collision).
Turbulent flow or microturbulence can have the character of the micro cyclone of many normally 10-15mm on a small scale.Angled surface, sharp edges and the interruption of blade 15 or the structure of zigzag have been served as vortex generator, have produced many vortexs along each tributary.The size of these vortexs is all very little, and contaminate particulate is involved in the air-flow.
The vortex pattern that blade 15 produces is believed to comprise the horizontal eddying motion of a linear parallel in blade, its size depends on blade pitgh, length of blade and width of blade, the vortex pattern also comprises a series of despun vortex structures, and its size depends on the leaf-teeth 16 of blade.Near the blade 15 flow velocity is considered to be lower than basically mean flow rate.
Although the zone of microturbulence only is confined to each channel center, the big turbulent flow in each tributary has guaranteed that the tributary is by this zone, so that the particle in the tributary stands the turbulent flow of particle scale.And, being confined to the central area in each saturating road by turbulent flow on a small scale, the overall presure drop by coalescent equipment also is minimized.
Described above only is one embodiment of the present invention, under situation about not departing from as the scope of the invention defined in the appended claims, can also carry out conspicuous for a person skilled in the art improvement in addition.Such as, although this mixing with reference to particle in the air-flow of tool of the present invention is illustrated, the present invention also can be applied to the mixing in other fluid stream, for example liquid.
In addition, the shape of blade and structure also can change.Fig. 7 (a)-(e) has enumerated some alternative blade shapes that can be used for the above coalescent equipment.
Although blade 15 preferably has leaf-teeth 16, concentrate on the back to back downstream area of blade with the reinforcement microturbulence and with it, these are not necessary to forming microturbulence.Turbulent region can produce (such as shaft-like, strip, aliform etc.) by the blade of any suitable configuration on a small scale, if blade is arranged in the wake flow of preceding guide vane one by one, and be spaced apart wake flow is completed between two continuous blades, so just the small-scale turbulent area can be concentrated between two continuous blades.
