The utility model discloses an establishing horizontal flow distribution plate in the nozzle, having strengthened the air current disturbance, the burning that is favorable to catching fire is stable, has avoided the emergence of gas powder lamination, simultaneously, the dilatation joint that nozzle, flow distribution plate exit end set up has been avoided making because of the high temperature the nozzle warp, has improved life.
Description
Technical field
The utility model relates to a kind of coal powder burner, particularly relates to a kind of high temperature resistant, oxidation resistant coal dust spout.
Background technology
Coal dust spout directly by the hyperthermia radiation of furnace flame, burning out than being easier to, causing various types of coal burner to damage.Particularly in recent years, each producer that uses uses soft coal, and spout mechanical strength is reduced, and the phenomenon that spout burns out is of common occurrence.Existing coal dust spout adopts heat-resistance stainless steel monoblock cast to form, also often occur spout Yin Wendu too high in use procedure and deform, also there is the phenomenon of gas powder layering simultaneously, seriously destroy normal pneumatic condition furnace in stove, burning is worsened, affects economy and the reliability of burner operation.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of high temperature resistant, oxidation resistant coal dust spout to solve the problem of spout because of the gentle powder layering of high temperature deformation.
The utility model solves the technical scheme that its technical problem adopts: described high temperature resistant, oxidation resistant coal dust spout comprises spout shell, nozzle, flow distribution plate, the port of export of described spout shell inwardly shrinks with proper angle, described nozzle is located in described spout shell, surrounding is connected by deep floor, described flow distribution plate comprises three, and lateral separation is located in described nozzle.
In a kind of preferred embodiment of high temperature resistant, the oxidation resistant coal dust spout provided at the utility model, the import and export end of described nozzle all extends beyond described spout shell, and the port of export of described spout shell, nozzle, flow distribution plate is all set to the inclination angle of 20 °.
In a kind of preferred embodiment of high temperature resistant, the oxidation resistant coal dust spout provided at the utility model, the surrounding of described nozzle exit end and the middle part of the described flow distribution plate port of export are equipped with dilatation joint, and described dilatation joint width is no more than 6mm.
In a kind of preferred embodiment of high temperature resistant, the oxidation resistant coal dust spout provided at the utility model, described coal dust spout adopts the monoblock cast of rare earth alloy heat-resistance and wear-resistance steel to form, and its wall thickness is 12mm, and operating temperature can reach 600 ~ 1200 DEG C.
Compared with prior art, the beneficial effect of high temperature resistant, the oxidation resistant coal dust spout that the utility model provides is:
One, by establishing horizontal flow distribution plate in described nozzle, enhancing flow perturbation, being conducive to ignition and stablizing, avoiding the generation of gas powder lamination;
Two, by arranging dilatation joint at described nozzle, the flow distribution plate port of export, avoiding Yin Wendu too high and make described nozzle variant, improve service life.
Accompanying drawing explanation

Described high temperature resistant, oxidation resistant coal dust spout 1 comprises spout shell 11, nozzle 12, flow distribution plate 13, the port of export of described spout shell 11 inwardly shrinks with proper angle, described nozzle 12 is located in described spout shell 11, surrounding is connected by deep floor 14, described flow distribution plate 13 comprises three, and lateral separation is located in described nozzle 12.
The import and export end of described nozzle 12 all extends beyond described spout shell 11, and the port of export of described spout shell 11, nozzle 12, flow distribution plate 13 is all set to the inclination angle of 20 °.
The surrounding of described nozzle 12 port of export and the middle part of described flow distribution plate 13 port of export are equipped with dilatation joint 15, and described dilatation joint 15 width is no more than 6mm, avoid Yin Gaowen and produce thermal expansion to cause described nozzle 12 to be out of shape.
During concrete enforcement, described coal dust spout 1 adopts the monoblock cast of rare earth alloy heat-resistance and wear-resistance steel to form, its wall thickness is 12mm, operating temperature can reach 600 ~ 1200 DEG C, has enough high temperature resistant, non-oxidizability, simultaneous adaptation machined, described dilatation joint 15 is sawed out by toothless saw, its width is fixed with gear piece, and preferably, described dilatation joint is 6mm.
Compared with prior art, the beneficial effect of high temperature resistant, the oxidation resistant coal dust spout that the utility model provides is:
One, by establishing horizontal flow distribution plate 13 in described nozzle 12, enhancing flow perturbation, being conducive to ignition and stablizing, avoiding the generation of gas powder lamination;
Two, by arranging dilatation joint 15 at described nozzle 12, flow distribution plate 13 port of export, avoiding Yin Wendu too high and described nozzle 12 is out of shape, improve service life.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included within scope of patent protection of the present utility model.
