Technical field
The utility model relate to a kind of for generation of with managing or the vortex of tangential speed component that flow direction in fluid stream in circular passage is vertical, wherein this vortex has a central columniform guide way and the guide blades being circumferentially uniformly distributed, firmly arranging at this guide way, and these guide blades extend radially outwardly in fluid stream until an inwall of this pipe or circular passage and bending in flow direction.
In addition the utility model relates to a kind of burner, and this burner comprises at least one such vortex.
Background technology
This type of burner and vortex such as gasifying carbonaceous fuels to manufacture forming gas.In the burner of external mix with oxygen-containing gas part oxidizing carbonaceous fuel (that is, in the burner, this fuel and this oxygen-containing gas do not carry out premixed, but to import in a Mixed Zone separatedly and to be lighted there), importantly realize the abundant mixing of this oxygen-containing gas and this fuel, to accelerate the partial oxidation reaction of the chemistry between these reaction partners (Reaktionspartnern) and to obtain the mist of maximum yield.
Such as in the case of liquid fuel by realizing fuel and the abundant mixing of oxidant in flame region with high pressure and the atomization of less droplet size.When gasifying the dry coal ash being transported to this burner by means of carrier gas, the abrasive action (Schleifwirkung) rising through this coal ash of nebulizer gas pressure causes the undesirable increase at burner tip place abrasive wear.Therefore select another kind of approach when coal gasification, namely to be increased by turbulent flow by a vortex in the oxidant loading part at this burner tip place and spray dispersion (Strahlaufspreizung) strengthens the mixing of these reaction partners.At the oxidant stream that the impact of this vortex flow is axial, this vortex flow provides the inside and outside recirculation of the height of combustion product and therefore provides high combustion intensity.
Owing to just to flow and velocity gradient precipitous in transitional region between refluxing result in strong turbulent flow at this, this turbulent flow is promoting the chemical reaction between this fuel and this oxygen-containing gas.

When the rotation impulse of this oxygen-containing gas is excessively strong, the backflow that the combustion engine of this heat turns back in this burner tip increases, and this causes heating and the destruction of this burner tip.
Therefore the vortex flow ratio for each burner and often kind of fuel is optimized by the adaptation of the correspondence of this vortex.
EP1221572B1 discloses this type of adapter.In a feeding pipe for the central authorities of oxidant, arrange to have one with the inflow side of rounding and the cylindrical guide body of outflow side that terminates with acute angle.The volution blade of the inside be radially directed towards is had in the circumferentially arrangement of the compresses lower section of this guide body.These blades are fixed in feeding pipe by the line of rabbet joint and tongue in this guide body for the tolerance of thermal expansion.This guide body has a medium pore for the axial flow portion of oxidant in one embodiment, also can reduce the pressure loss by this guide body under close to identical vortex effect thus simultaneously.Depend on the diameter of this medium pore, therefore this axial flow portion is affected, and this axial flow portion contributes to reducing the refluxing portion of hot reacting gas to this burner tip.
The shortcoming of the arrangement advised is the high manufacture cost of these volution blades and installs cost.These inner volution blades are shaping by the outer surface of this central guide body of processing.Each volution blade must be fastened in this flow channel individually through the tongue-line of rabbet joint of a form fit.
Also the arrangement of a vortex in fuel channel is once advised in the past.Known a kind of burner for gasification of liquid fuel, clout and waste material from DE20001421U1, the device that this burner uses as the substitutability for dispersing liquid fuel comprises vortex, free-jet nozzle or Venturi nozzle, wherein this liquid fuel passage should have a reduced diameter portion respectively, and this oxidant channel is arranged in around this fluid passage concentrically.Shortcoming is, when flow in fuel comprises solid fuel, this vortex has high wearing and tearing in this flow in fuel.
In the cooling improving this gasification combustor, advise in EP2743579A1, single-piece ground forms the whole burner tip comprising volution blade, and manufactured by the successively fusing of metal alloy by means of optionally laser sintered (Laser-Cusing, optionally laser fusion).Therefore should arrange the cavity structure that thin wall-type, available flow of cooling water is passed at this burner tip place, these cavity structures allow a common cooling sending into passage and these volution blades.Shortcoming is, this burner tip only can manufacture new complete burner tip by height to the adaptation of fuel changed or the optimization of flow behavior and realize with expending.The replacing of independent wearing part is impossible.Because this manufacture method also causes the selection of material be applicable to best respectively for each independent burner element to be impossible.

Detailed description of the invention
This gasification combustor be such as one for sending into oxidant at internal channel and sending into two channel burners of fuel at outer tunnel.Such burner is arranged in for gasifying carbonaceous fuels usually to manufacture in the shell of the gasification reactor of forming gas, and there is at least one for first fluid stream, in particular for the central internal channel (pipe 9) of the oxidant containing oxygen, and at least one is for second fluid stream, in particular for coal ash pneumatic supply, surround the circular passage of mesotube 9 concentrically.
As shown in Figure 1, the vortex had for generation of the tangential speed component vertical with axial flow direction is arranged in the pipe 9.This vortex comprises a central columniform guide way 1 and the guide blades 2 being circumferentially uniformly distributed, firmly arranging at this guide way, these guide blades extend radially outwardly in fluid stream until this center axis pipe 9 inwall in.In order to the assembling of this vortex, the gap size that minimum must be had between the outward flange 6 and the inner face of this pipe 9 of these guide blades 2.The columniform outline of these guide blades 2 is set to for making this vortex be inserted in a pipe in this embodiment.Deviation in this outline, such as rotate safety piece, can realize equally based on manufacture method flexibly in the coefficient projection additionally of Guan Zhongyu cannelure.
These guide blades 2 are bending in flow direction, and spirally in flow direction around the guide way 1 of these central authorities, and have a progressive inclination angle relative to flow direction at this, wherein equal zero at inflow side 5 place and reach its maximum on outflow side 7 in the inclination angle of these guide blades 2.In this inflow region, these guide blades 2 are parallel to flow direction or orientation in flow direction thus, and these guide blades have the curvature of increase in flow direction.On this outflow side 7, these guide blades 2 are set to have the allowable angle of inclination (Fig. 3) tilted relative to axial flow.
This guide way 1 has a collision tip 3 with the central authorities of profile best on fluid technique on its inflow side, and this profile guides this fluid stream around this guide way 1.In the embodiment that another is favourable, this guide way 1 not colliding most advanced and sophisticated 3 is formed as pipe fitting, its mode is, this guide way has a central continuous print axial hole 4 (Fig. 2), this axial hole can make this fluid stream flows pass or be suitable for receiving course control device, such as flow-sensint unit, flame monitor or signal transmitting apparatus.
Configuration with the guide way 1 of a collision most advanced and sophisticated 3 and a central axial aperture 4 define one flexibly can be adaptive solution.With this can, provide a citation form of this vortex, it is favourable applicable cases that this citation form is used for one of them collision most advanced and sophisticated 3, and for applicable cases that wherein this central axial aperture 4 is opened in both sides after this collision most advanced and sophisticated 3 disconnects.
This vortex is fixing in order to its axis, and by these end faces, on the outflow side 5 of guide blades 2, in a cross section narrowing 10 of this pipe 9, loosely supports.Another kind of axial firmly possibility is, these guide blades 2 at its outward flange 6 place respectively only in first section 8 towards inflow side according to Fig. 1 to 3 larger diameter manufacture with this pipe before this cross section narrowing 10, and this vortex depression 12 loosely in the outward flange 6 of these guide blades 2 formed like this is bearing in (Fig. 1) in the cross section narrowing 10 of this pipe 9.
The cross section narrowing 10 also formed in circular passage in the same manner in this pipe 9 can be one around diameter ladder, or be also only made up of the independent projection at the inwall place at this flow channel, these guide blades 2 are supported in these projections.In order to change the vortex of wearing and tearing by simple mode, the overall diameter with these guide blades 2 of fit tolerance will be chosen as and be less than this pipe 9 or circular passage interior diameter.
That at least one arranges securely at the inwall place of this pipe 9 or circular passage, for rotational stop part 11 safety piece that rotates of one of these guide blades 2.This rotational stop part is preferably arranged in larger pipe cross section, and can be such as straight pin shown in figure 2, this straight pin to extend in the free cross section of this pipe more than 9 millimeters by a radial in the pipe wall hole, and fixes this vortex relative to torsion.
This kind of special production method of need of production with the economy of the vortex of the guide blades 2 of progressive curvature.In a cutting type forming part method, produce cost may be too high.The laser sintered method of recommendations for selection for small lot batch manufacture, also referred to as Laser-Cusing or short SLS metal.An only production stage, the complicated function part be made of metal is produced from the 3D data of vortex (Fig. 3) when SLS.This kind of pulverizing metal with thin layer apply and carry out melting by laser in the mode of giving profile.So this object layer by layer ground produces with the geometry preset by 3D model.Consider such as aluminium, steel, titanium or nickel-base alloy as the suitable metal for SLS, wherein nickel-chromium alloy shows as the solution be particularly suitable in this suggestion.This vortex finally at least grinds at outward flange 6 place of these guide blades 2, to ensure the tolerance dimension of the hope of the pipe 9 for same processing.
This vortex is being installed in the circular passage of a burner, when being namely installed in the annular gap between an interior pipe 9 and a concentric outer tube, this guide way 1 is thus set size, make its interior diameter of this guide way only slight beyond the overall diameter of the pipe 9 with the tolerance for compensating different calorifics material behavior, and therefore can be plugged on this pipe 9.Another kind of possibility is, the interior diameter of this guide way 1 is equal with overall diameter with the interior diameter of this interior pipe 9 with overall diameter, and is coaxially connected with pipe 9 in its side by this guide way 1, such as, weld, and makes this guide way 1 form a section of the wall of this pipe 9.
The method of operation according to the utility model device:
Oxidant and burning ashes and suitably time other these two medium streams of gaseous medium in the pipe 9 of this burner internal in these central authorities and in concentric circular passage, be axially transferred to this burner tip, and react to each other in flame region, the carbon part wherein sent into is oxidized to carbon monoxide.
By the vortex arranged in this front pipe 9 in central authorities, vortex flow is caused in the oxidant or oxygen stream of axis, that is, this air-flow when discharging from this burner except also there is a rotary motive components around component motion its main flow direction external of burner tip substantial axial originally.This vortex flow part causes the beam of this central oxygen stream to be widened and turbulence excess in the coal ash of discharging from concentric circular passage-carrier gas stream due to revolving force after discharging from burner tip.These two kinds of consequences increase the contact surface between air-flow and cause the mass exchange of strong radial direction and therefore cause mixing fast.
According to the utility model, when vortex length be greater than 1 relative to the ratio of guide blades diameter and the inclination angle of these guide blades 2 on this outflow side 7 between 20 ° and 45 ° time, obtain and effectively mix.
Due to the progressive curvature of these guide blades 2, first the flowing stream on inflow side 5 hit collision most advanced and sophisticated 3, and outwards deflect into the leading edge of guide blades 2 directed in the flowing direction from it.This fluid stream is directed until its outflow side 7 along bending guide blades 2 when the Angulation changes continued, and obtains at this rotational component (vortex) preset.
The tangential reaction force acted on due to deflect flow on vortex is received by the rotational stop part 11 arranged securely at the inwall place of this pipe 9 or circular passage and is exported in this tube wall.
When flow into this guide way 1 this collision tip 3 the function of reduction turbulent flow be from well known in the prior art.But the manufacture method of advising provides following possibility: when not have in manufacturing technology additional expend, with different variant (with/do not collide most advanced and sophisticated 3, the guide way 1 as solid cylinder/hollow cylinder) manufacture this vortex.Such as guide body 1 can preset a collision most advanced and sophisticated 3 in the variant that can use flexibly, and this guide body 1 is configured to hollow cylinder simultaneously.
For the use of the guide way 1 for receiving course control device, be maybe advantageously separated this collision tip 3, the hole of the axis of these central authorities is opened in both sides and for installation, such as, for the installation of flame monitor subsequently, be come-at-able.Due to this manufacture method flexibly, this bore dia is variable and can be suitable with equipment to be installed.In order to fix these equipment to be installed, in hole 4, nature can be sagging or protruding by laser sintered realization.
Same it is achieved that this guide way 1 is used for other objects or when without any the reinforcement being only used for axial flow component when installation by perforate 4.If pipe fitting should be configured to the guide way 1 in the hole 4 of the centre coaxial relative to burner axle, the air-flow of these central authorities flows through this vortex when not affecting the flow direction of its axis, in the air-flow of outside, form vortex steadily on the contrary by these guide blades 2.The conversion zone of the heat of this burner flame is offset from this burner tip by this higher axis stream ratio, but is when keeping this reacting gas to rotate around this burner axle.Due to the larger distance of the flame region of burner tip, the heat load of material is not too high, and the wearing and tearing at this burner tip place can be lowered.
Because being different from this fluid stream of prior art is not the smooth guide surface hitting constant inclination, but redirect to from the flow direction of its axis all the time in spiral flowing, the vortex advised causes on this inflow side 5, almost do not have eddy current and the therefore only very little pressure loss, and correspondingly reduces in the wearing and tearing at these guide blades 2 places.Show in the result of corresponding research, the axial dimension of this vortex and therefore this guide blades length should be larger than the yardstick of its radial direction, formed to realize best vortex in the medium of this flowing.
Due to the progressive curvature of these guide blades 2, in addition simple mode can be used, the local condition of vortex flow component in actual use with concrete this produced by vortex is suitable, its mode is, can be manufactured as described above at the different inclinations angle of these guide blades 2 of outflow side 7 place relative to the flow direction of axis by the shortening of this vortex and these guide blades 2.Its precondition is that the minimum dimension of the length of this vortex should be greater than this guide blades diameter.
