According to one embodiment of present invention, the inclination angle of the first surface of blade is configured to variable.This means: in the first of first surface, blade is certain special value with respect to the inclination angle of the principal direction of air-flow, and in the second portion of first surface, the inclination angle of blade is other numerical value, just is different from the numerical value at first inclination angle.In an embodiment of the present invention, the inclination angle of guide vane reduces towards the outward flange of blade from the base portion of blade usually.Simultaneously, the inclination angle of straightening vane increases from blade first edge towards its second edge along the principal direction of air-flow usually.
Blade for example can by reverse, warpage, bending, cast form be configured to have the above-mentioned inclination angle of stating.Preferably, by reversing or the warpage blade makes blade have variable inclination angle, because simple like this and economical.
Can be by for example on first surface, folding a limited number of inclination angle or forming variable inclination angle by making first surface not have any obvious folding line ground smooth change.In an embodiment of the present invention, blade is set to have one or more discontinuous sections, i.e. folding line, and the inclination angle of the first surface of blade changes at the folding line place.
Embodiments of the invention relate to a kind of method that is used for improving in the centrifugation of the particle of the cyclone separator that comprises the separation chamber, by:
-the air-flow that will comprise particle is directed to separator chamber via the inlet connecting portion that is positioned at separator first end;
-make the said flow that contains particle be directed to along at least one guide vane that is arranged in inlet connecting portion and/or the separator chamber, make the other end motion of air-flow thus, and particle is directed to by the outer wall towards cyclone separator towards separator chamber;
-air-flow is derived from separator chamber via the discharge connecting portion that is arranged in the cyclone separator other end; And
Near the central part of cyclone separator, run into the particle of guide vane, compare, thereby be to be directed to towards the outer wall of cyclone separator with bigger inclination angle to advance with the particle that runs into guide vane at the central part of distance cyclone separator at a distance.Preferably, make air-flow carry out vorticla motion by at least one guide vane towards the separator chamber other end.
According to one embodiment of present invention, the inclination angle of the first surface of guide vane increases along the principal direction (promptly the edge is perpendicular to the direction of the longitudinal axis of blade) of air-flow.This means that at gas gas at first runs into the first of the first surface of blade when its principal direction is moved, this first becomes an inclination angle with respect to the principal direction of air-flow.When gas (mainly being on the direction at the central shaft of separator chamber) on its principal direction when the first surface of blade moves, the inclination angle of first surface little by little increases or staged ground (for example at the folding line place) increases.
According to one embodiment of present invention, the inclination angle of the first surface of straightening vane reduces along the principal direction of air-flow.This typically refers to first surface with respect to directly leading to the inclination angle of the direction of discharging connecting portion from the inlet connecting portion.In this case, the violent air-flow that straightening vane will be discharged from separator chamber is led directly, so that air-flow is parallel to the central shaft of discharging connecting portion and/or the central shaft of separator chamber.
The inclination angle of the first surface of straightening vane also can be preferably zero degree, and in this case, the first surface of blade is parallel to the principal direction of air-flow.The whole surface of blade can be in identical inclination angle, and perhaps this inclination angle can be variable in the following manner: make this inclination angle bigger on for zero degree another part at first surface on the part of first surface.
According to one embodiment of present invention, the first surface of guide vane is set to change in the following manner along the direction (promptly radially going up) that is substantially perpendicular to the principal direction of air-flow at least with respect to the inclination angle of the principal direction of air-flow: the inclination angle is a maximum with the most related place of central shaft, and towards the wall of cyclone separator fifty-fifty (on average) reduce.By this characteristic, with when entering separator chamber those particles of more close wall compare, the particle that enters separator chamber with central shaft can more effectively be led towards wall relatedly.This means that the same surperficial inclination angle of blade can cover the different piece of the surf zone of blade base place and blade outer edge.For example, the inclination angle of the major part of the base portion of blade is preferably bigger than the outer peripheral inclination angle of blade.The inclination angle of straightening vane also can be set to by identical mode radially change fifty-fifty.
According to one embodiment of present invention, cyclone separator also comprises first central member, first central member is configured to substantially related with the central shaft of the central shaft of inlet connecting portion and/or separator chamber, to leave central shaft, towards the wall of cyclone separator air-flow to be led.Therefore, can hinder or reduce air-flow in the central axis use central member of cyclone separator.The shape of first central member can be set to taper, and its principal direction along air-flow is expanded towards guide vane.The expansion shape of central member makes air-flow leave the central shaft of cyclone separator and is directed to towards the outer wall of separator, and has strengthened the guiding to air-flow thus.Correspondingly, it is the taper shape that comes to a point that first central member can be arranged in the guide vane back, so that optimize flox condition.
According to one embodiment of present invention, cyclone separator also comprises second central member, and this second central member is provided with the central shaft of discharging connecting portion substantially relatedly.One or more straightening vanes may be attached to second central member of this discharge connecting portion, or otherwise are provided with this second central member relatedly.The shape of this central member can be set to come to a point along the principal direction of air-flow.The shape that comes to a point of this central member (for example taper) guiding air-flow turns back to related with central shaft, and makes air-flow become even thus on its fluid cross-section.
Inlet connecting portion and discharge connecting portion all can have separate central member.The single-piece that the central member of inlet connecting portion and/or the central member of discharging connecting portion also can form as one with a central member that may be arranged in the separator chamber, and/or the central member of inlet connecting portion and discharge the single-piece that the central member of connecting portion forms as one each other.In this case, the central member of one always extends to discharge connecting portion from the inlet connecting portion via separator chamber along its center line.
According to one embodiment of present invention, central member is related with the central shaft of separator at least cylindrical.Columniform central member can prevent that gas from entering with the central shaft of separator chamber relatedly, and gas is driven the wall to separator chamber thus.Cylindrical centre element for example can be tubulose.
According to one embodiment of present invention, at least some in guide vane and/or the straightening vane are set at its base portion place related with this central member.These blades can be fixed to central member by for example welding.
Advantage of the present invention is the centrifugation that has strengthened at the material that will separate in cyclone separator.
Even an advantage of the invention is can reduce significantly stop material to be separated that gas and this gas comprised along the central shaft of cyclone separator by this cyclone separator.
Another important advantage of the present invention is to reduce the pressure drop relevant with separative efficiency.
Can be preferred for from air-flow, separating the method for material to be separated according to cyclone separator of the present invention.The scheme that provides in the content of dependent claims and example shown in the drawings is suitable for said method equally.
Typically, cyclone separator is set to vertically use, thereby the inlet connecting portion is set at discharge connecting portion below.Gas flow to be purified is introduced into this cyclone separator in the bottom of cyclone separator, and purifying gas flow is discharged this cyclone separator from the top of cyclone separator.Obviously, cyclone separator also is suitable for flatly using.
In a preferred embodiment of the invention, separator chamber is provided with at least one sorting hole, and isolated material can be discharged via above-mentioned sorting hole from gas to be clean.Sorting hole can be arranged on appropriate position in the wall of separator chamber.Usually significantly less than the diameter of inlet connecting portion and/or discharge connecting portion, the diameter of sorting hole typically is about 0.07-0.15m to the diameter of sorting hole.If cyclone separator will be installed in vertical position (promptly vertically install), then can be, be that the bottom of separation chamber is provided with drain tank, to should sorting hole being set drain tank in the bottom of separation chamber.In this case, material to be separated accumulates to drain tank along the wall of separator chamber, and discharges via tap from this drain tank.Bottom at horizontally disposed cyclone separator also can be provided with drain tank.

Fig. 3 a, Fig. 4 a and Fig. 5 a illustrate the example of tubular inlet connecting portion 3 edges of cyclone separator perpendicular to the cross-sectional figure of the direction of the principal direction of air-flow.In Fig. 3 a, Fig. 4 a and Fig. 5 a, the direction of air-flow is for vertically to pass paper from the observer.Fig. 3 a, Fig. 4 a and Fig. 5 a illustrate the stereogram of guide vane 8a.When Fig. 3 b, Fig. 4 b and Fig. 5 b illustrate from the direction observation of arrow d, the situation of the top of the tubular inlet connecting portion shown in Fig. 3 a, Fig. 4 a and Fig. 5 a.The purpose of these examples is to explain the implication of the first surface of guide vane 8a in this application with respect to the inclination angle of the principal direction 10 of air-flow.In this example, blade 8a is tabular uniformly and is straight that blade 8a is attached to the central member 15a that is provided with central shaft at its base portion 9 places relatedly.Not shown central member in Fig. 3 b, Fig. 4 b and Fig. 5 b.The longitudinal axis 18 of blade 8a is set to be parallel to the radius of connecting portion 3 of entering the mouth, that is to say, this longitudinal axis 18 from central member 15a vertically towards the wall of inlet connecting portion 3.In Fig. 3 a and Fig. 3 b, the first surface 12 of blade 8a is set to the inclination angle with respect to 10 one-tenth 90 degree of principal direction of air-flow, and promptly in Fig. 3 a, first surface 12 is parallel to paper.In Fig. 4 a and Fig. 4 b, blade 8a reverses 45 degree from the position of Fig. 3 a and Fig. 3 b around its longitudinal axis 18, and in this case, first surface 12 is 45 degree with respect to the inclination alpha of the principal direction 10 of air-flow.In Fig. 5 a and Fig. 5 b, blade 8a turns round around its longitudinal axis 18 from the position of Fig. 3 a and Fig. 3 b and turn 90 degrees, and in this case, first surface 12 is a zero degree with respect to the inclination alpha of the principal direction 10 of air-flow, and promptly first surface 12 is parallel to the direction of air-flow.
Fig. 6 a is illustrated in the implication that the inclination angle on the principal direction 10 of air-flow changes, and is attached to the implication that first surface 12a, the 12b inclination angle on the principal direction 10 of air-flow of the guide vane of central member 15 increases in this particular case.When gas moves on its principal direction 10, at first run into the 12a of first of the first surface of blade, this first is with respect to 10 one-tenth a certain inclination angles of principal direction (for example 10 degree) of air-flow.The 12a of first along the first surface of blade on its principal direction 10 moves along with gas, the inclination angle of first surface at folding line 19 places, especially sentence following manner and increase at a 19a: make second portion 12b with respect to the inclination angle of the principal direction 10 of air-flow greater than the inclination angle of the 12a of first with respect to the principal direction 10 of air-flow.The inclination angle of second portion 12b for example can be 40 degree.
First surface 12a, the 12b that Fig. 6 b illustrates guide vane is along the direction that is substantially perpendicular to the principal direction of the air-flow (implication of the mean change at) inclination angle radially promptly.In this example, the 12a of first with respect to the inclination angle of the principal direction 10 of air-flow less than the inclination angle of second portion 12b with respect to the principal direction 10 of air-flow.Most of 12b ' of the base portion of blade is with respect to the inclination angle of 10 one-tenth bigger of the principal directions of air-flow, and sub-fraction 12a ' 10 one-tenth less inclination angles of principal direction with respect to air-flow are only arranged.Observe along the direction of the longitudinal axis 18 of the blade radial direction of cyclone separator (promptly along), outer peripheral most of 12a of blade " with respect to 10 one-tenth less inclination angles of principal direction of air-flow, and only has sub-fraction 12b " with respect to the inclination angle of 10 one-tenth bigger of the principal directions of air-flow.In this application, this characteristic is described by following explanation: the inclination angle of first surface 12a, 12b average with central shaft 13 related ground maximums, and on average towards the wall of cyclone separator that is radially the y direction of blade (promptly along) reduces.
Fig. 7 a is the stereogram according to the cyclone separator 1 of second embodiment of the invention.The inlet connecting portion 3 of cyclone separator 1 is provided with guide vane 8a.Being shaped as of central member 15 is cylindrical.Central member 15 is provided with the central shaft of separator chamber 2 relatedly, and extends to discharge connecting portion 4 from inlet connecting portion 3 substantially.Central member 15 stops air-flow to enter with the central shaft of separator chamber 2 relatedly, and forces the wall 11 of the close more separator chamber 2 of air-flow thus.Guide vane 8a is attached to central member 15a by its base portion 9.Blade 18a substantially perpendicularly stretches out towards the wall 11 of cyclone separator from position that its base portion is attached and the direction of central member 15a and the direction of central shaft.It is variable that the inclination angle of the first surface 12 of blade 8a is configured to as follows: make this inclination angle increase along the principal direction 10 of air-flow (in other words along blade laterally).The first surface 12 of blade 8a has two folding lines 19,20, and these two folding lines 19,20 are divided into three part 12a, 12b, 12c with first surface.Folding line also can be different numbers, for example is 1,3,4,5 or more.The variation at the inclination angle of first surface also can be set to continuous at least in part, without any tangible folding line.In this example, the 12a of first is very little with respect to the inclination angle of principal direction 10, is about 5 degree.The inclination angle of second portion 12b is about 25 degree, and the inclination angle of third part 12c is about 45 degree.With inlet connecting portion 3 relatedly, central member 15a is taper and is configured to this central member 15a and becomes more and more wideer along the principal direction 10 of air-flow.This conical in shape steering current leaves central shaft and flows to the wall 11 of cyclone separator.The arrow 30 that marks by dotted line show guide vane 8a how with air-flow towards wall 11 guiding.Being positioned at the central member 15b that discharges connecting portion 4 places is taper, and this central member 15b comes to a point along the principal direction 10 of air-flow, it is related with the central shaft 14 of discharging connecting portion 4 that this helps steering current to get back to, thereby and help air-flow to become even on its fluid cross-section.
Fig. 7 b illustrates cyclone separator according to an embodiment of the invention, and the discharge connecting portion of this cyclone separator is provided with straightening vane 8b.The purpose of these blades is that the violent air-flow of discharging from separator chamber 2 is led directly.
Fig. 8 illustrate wall from the inlet connecting portion along the direction that is parallel to radius when central member 15,15a and central shaft are looked, and be arranged on blade in the inlet connecting portion and central member similarly some blades and central member among Fig. 7 a and Fig. 7 b.In Fig. 8, it is variable that the inclination angle of guide vane is configured to along the direction different with Fig. 7 b with Fig. 7 a.Blade steering current among Fig. 8 flows counterclockwise, and the guide vane steering current among Fig. 7 a and Fig. 7 b flows clockwise.
The inclination angle of the guide vane in the schematically illustrated one embodiment of the invention of Fig. 9 changes.Guide vane 12 is attached to central member 15, folding line 12 ' be arranged on this blade along dotted line.Folding line 12 ' the part 12b of the blade 12 that is arranged in central member 15 those sides, the first surface of blade is 50 degree with respect to the inclination angle of the principal direction 10 of air-flow.When particle A ran into the first surface of blade near central member 15, particle A was directed in the part of the inclination angle of blade 12 average out to 50 degree for the whole length of this blade along the first surface of blade 12.When particle B ran into the first surface of blade at the middle part of blade, particle B was that 40 parts of spending are directed to the folding line in the blade by the inclination angle of blade at first, and particle B is that 50 surfaces of spending are directed to by the inclination angle of blade afterwards.Therefore, be used for inclination angle that particle B is led on average less than the inclination angle that is used for particle A is led.When running into the first surface of blade near the outward flange of particle C at blade, particle C is directed in the part of blade tilt for whole length average out to 40 degree of blade 12 along the first surface of blade 12.Therefore, the first surface of blade is used for inclination angle that particle C is led fifty-fifty less than the inclination angle that is used for particle A and particle B are led.In this way, with when entering separator chamber the particle of more close wall compare, the particle that enters separator chamber with central shaft can more effectively be led towards wall relatedly therefrom.Certainly, the inclination angle among Fig. 9 is that the mode with example provides, and changes in can be in claims given scope in these inclination angles.
The present invention is not limited to the above embodiment that describes by example, but should broadly be explained in by the protection domain that appended claims limited.
