Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
In the utility model, when not doing contrary explanation, the noun of locality used is if " upper and lower, top, the end " is normally for direction shown in the drawings, or for vertically, on vertical or gravity direction, or each parts mutual alignment relationship description word of dependency structure equipment under normal service condition; Similarly, for ease of understanding and describing, " inside and outside " refers to profile inside and outside relative to each parts itself, but the above-mentioned noun of locality is not limited to the utility model.
As shown in Figure 3 and Figure 4, the utility model discloses a kind of gasification burner tip, this gasification burner tip comprises the oblique jet pipe 3 of burner seat 1, core jet pipe 2 and Duo Gen, core jet pipe 2 penetrates in this burner seat 1 from the outside vertical of burner seat 1, and many oblique jet pipes 3 are arranged symmetrically with around core jet pipe 2 and penetrate obliquely in burner seat 1 from outside.The center stream imported by core jet pipe 2 and the oblique stream imported by oblique jet pipe 3 can clash and combustion gasification by the joint P inside burner seat 1, the inner side of burner seat 1 is also formed with the circumferential protective layer arranged around joint P, mainly to suppress oblique stream, comprise the impact of combustion gas to the furnace wall of vapourizing furnace 5.
Wherein, for improving gasification efficiency, enhancing mass and heat transfer, on the basis that existing fuel and vaporized chemical (such as oxygen) coaxial-type are carried, be improved to respectively with center stream and oblique stream form by core jet pipe 2 and oblique jet pipe 3 ejection, and then there is head-on collision and combustion gasification at the joint P place of the inner side of burner seat 1, the head-on collision of two strands of jets can make solid particle fuel more uniformly disperse also short mix in gas phase media, to have better mixed effect between fuel and vaporized chemical compared to coaxial jet structure.And joint P is on the inner side certain distance of burner seat 1, can reduce back-mixing, also avoid and causes high temperature failure to burner itself.After head-on collision, speed reduces relatively, also reduces the length of combustion flame, thus the vapourizing furnace volume needed for reducing.
But, the oblique stream sprayed due to oblique jet pipe 3 generally has fair speed, even if having certain deceleration after head-on collision burning, but still there is suitable speed, certain impact failure can be caused to the furnace wall of vapourizing furnace 5, especially under long term, maintenance cost is also higher, or needs the furnace volume increasing vapourizing furnace to avoid impacting.In the utility model, be also provided with the circumferential protective layer around joint P especially for this reason, impact vapourizing furnace furnace wall to prevent oblique stream at a high speed.
As shown in Figure 3 and Figure 4, as a kind of preferred implementation of circumferential protective layer, be designed to the tubular shield cap 4 of built-in heat-stable material 41, the top of this shield cap 4 is connected to the inner side-wall 13 of burner seat 1, the internal ring wall of shield cap 4 is embedded with the cooling fluid coil pipe 42 arranged continuously along this internal ring wall, this cooling fluid coil pipe 42 is fixedly connected on the outside coolant pipe protective layer 43 (as SiC mould material etc.) covered by pin etc.Wherein, tubular shield cap 4 and burner seat 1 are connected as a single entity, and form high-temperature fuel combustion gasification passage in shield cap 4, high-temperature combustion gas acts on the internal ring wall of shield cap 4, namely on coolant pipe protective layer 43, by cooling fluid coil pipe 42 pairs of coolant pipe protective layer 43 continued down.After high-temperature combustion gas acts on internal ring wall, speed and temperature reduce greatly, thus effectively avoid oblique stream and high-temperature combustion gas to the erosion of vapourizing furnace furnace wall.
Particularly, in shield cap 4, by internal ring wall around inner cavity chamber's (i.e. high-temperature fuel combustion gasification passage) comprise the lower cone platform inner cavity chamber B that upper cone platform inner cavity chamber A that top is enlarging shape and bottom are enlarging shape, core jet pipe 2 and the oblique jet pipe 3 of Duo Gen are all communicated to upper cone platform inner cavity chamber A, and joint P is then preferably located in lower cone platform inner cavity chamber B.Like this, oblique Liu He center stream is pooled to joint P place through upper cone platform inner cavity chamber A.Accommodation center stream and two strands of oblique streams are convenient in the top enlarging of upper cone platform inner cavity chamber A, and the bottom convergent mouth of upper cone platform inner cavity chamber A is conducive to center and flows and the mixing of oblique stream.At joint P place, collide the bottom enlarging of the high-temperature gas after burning via lower cone platform inner cavity chamber B to external diffusion, the inner-wall surface of lower cone platform inner cavity chamber B has stop shock action to the high-temperature gas of diffusion and the oblique stream of part.Wherein, oblique jet pipe 3 all can need carry out designing or field adjustable according to technique relative to the bottom cone angle beta of the angle of inclination of core jet pipe 2, the top cone angle of upper cone platform inner cavity chamber A and lower cone platform inner cavity chamber B, can be 90 ° ~ 160 °.Certainly, the structure of shield cap 4 herein is only enumerated, if such as there are concrete needs, joint P also can be arranged in upper cone platform inner cavity chamber A.
Very large heat must be produced at the collision combustion potential at joint P place, the internal ring wall of shield cap 4 is formed and scorches, too temperatures involved is brought to neighbouring burner seat 1, core jet pipe 2 and oblique jet pipe 3, be thus necessary to carry out cooling fast and effectively, and keep the service temperature of burner seat 1.For this reason, be provided with the first cooling chamber 11 around core jet pipe 2 and the second cooling chamber 12 around many oblique jet pipes 3 in the burner seat 1 shown in Fig. 3 and Fig. 4, this second cooling chamber 12 is preferably communicated with adjacent cooling fluid coil pipe 42.First cooling chamber 11 and the second cooling chamber 12 are connected with independently water-in and water outlet respectively.Certainly, the first cooling chamber 11 and the second cooling chamber 12 both can separate mutually, can be used as independently cooling chamber, also can be interconnected, design according to specific needs.
As the another kind of embodiment of circumferential protective layer, circumferential protective layer is also without requiring being cover body in kind, and it can be preventing gas sheath.Such as, the inner side-wall 13 of burner seat 1 can be connected with rare gas element jet pipe, to eject the rare gas element protective layer as circumferential protective layer.As shown in Figure 9, when gasification burner tip is arranged on the furnace roof of vapourizing furnace, the rare gas element jet pipe forming preventing gas guard shield 4 along vapourizing furnace circumferentially, can form the hoop air-flow of circumference, to protect the circumferential internal protecting wall of vapourizing furnace.Preferably, rare gas element protective layer is CO
2preventing gas sheath.Described rare gas element jet pipe circumference is arranged on the intersection of the described inner side of close vapourizing furnace furnace wall and burner seat, to prevent oblique stream at a high speed to the impact of vapourizing furnace furnace wall and corrosion better.I.e. rare gas element jet pipe ejection CO
2, CO
2the uncompleted burned carbon particle reaction that can adhere to furnace wall generates CO, simultaneously stability heat, lowers the temperature, protect furnace wall further to the furnace wall of vapourizing furnace.
Selectable, the center stream imported by core jet pipe 2 can be vaporized chemical jet, then the oblique stream imported by oblique jet pipe 3 is flow in fuel.But in the embodiment shown in Fig. 3 and Fig. 4, the oblique stream imported by oblique jet pipe 3 is vaporized chemical jet.
