Abstract
The utility model discloses a bottom feeding nozzle for pneumatic transport, which is composed of a nozzle body and a nozzle cap body, wherein the nozzle cap body is arranged on the nozzle body which is provided with a feed opening and a discharge opening, the nozzle cap body is in a circular disc shape and the nozzle body is in a columnar shape. Because of the function of the nozzle cap body of the utility model, the ash is hard to enter the nozzle to block the nozzle, and the mixture of the fly ash after ejected from the side surface and other materials in the bed, and the diffusion in the bed are better than that of an open bore structure on the top. The residence time of the fly ash in the dense phase area of the bed is increased by the mixture of the fly ash after ejected from the side surface and other materials in the bed. The utility model is advantageous to burn off the carbon residue in the fly ash, advantageous to the normal running of the system and advantageous to the normal running of the bottom feeding circulating fluidized bed of the fly ash.
Description
One, technical field
The utility model relates to a kind of strength to be carried with raising nozzle in the end, relates in particular to the strength of raising Combustion technology of circulating fluidized at the bottom of a kind of flying dust and carries with raising nozzle in the end.
Two, background technology
In the prior art, owing to there is not top blind flange, in the running, may or carry the air quantity variation to cause lime-ash to enter because of the flying dust amount and cause obstruction in the standpipe, whole circulation system lost efficacy, if flying dust directly enters bed by standpipe, because it is higher to carry the conveying air velocity and the blast of flying dust, to be transferred wind after the circulation flying dust enters bed directly takes out of outside the bed, cause the gas-solid short circuit, perhaps carry wind to change in quality into air pocket in bed, this bubble is taken flying dust out of, therefore the time of staying of flying dust high temperature emulsion zone in bed reduces greatly, is unfavorable for burning of carbon residue in the flying dust.Gas-solid vertically mixes and laterally mixes relatively poor in the fluid bed, if there is not the nozzle of this structure, flying dust and conveying wind will vertically spray from the top, having worsened the gas-solid in the bed more mixes, after using this nozzle, flying dust sprays the mixing of other material in back and the bed from the side, because other material particular diameter is little in the size ratio bed of flying dust, will improve interior a fluidisation situation and an interior horizontal gas-solid troubled water greatly.
Three, technology contents
Technical problem: the utility model provides a kind of system that helps normally to move, and is particularly advantageous in the strength of raising the normal operation of recirculating fluidized bed at the bottom of the flying dust and carries with raising nozzle in the end.
Technical scheme: a kind of strength is carried with raising nozzle in the end, is made up of nozzle body and cap of spraying nozzle body, and the cap of spraying nozzle body is located on the nozzle body, is provided with charging hole and discharge opening on nozzle body.
Technique effect: 1. because the effect of cap of spraying nozzle body of the present utility model, make lime-ash be difficult for entering and cause obstruction in the nozzle, and flying dust sprays mixing of other material in back and the bed from the side and diffusion in bed is better than top drilling structure, flying dust sprays mixing of back and interior other material of bed from the side, increased the time of staying of flying dust emulsion zone in bed, help burning of carbon residue in the flying dust, normally move, help raising at the bottom of the flying dust the normal operation of recirculating fluidized bed thereby help system.2. nozzle is raised at the end that high chromium nickel rare earth alloy nozzle body and high chromium nickel rare earth alloy cap of spraying nozzle body are formed, and makes to the utlity model has high temperature resistant, wear-resisting advantage, guaranteed nozzle under mal-condition for a long time, stably work and do not lose efficacy.3. the utility model is raised its shape of nozzle the end of with and is set at disc and discharge opening is opened in the side of nozzle body, and it is more reasonable that gas-solid is flowed, therefore under the situation of identical material, because that flying dust washes away the wearing and tearing that cause is littler.In addition, discoidal structure helps ignition of the boiler and drags for the burnt process of beating after coke button and the coking, and is difficult for by coke button bonding and together take boiler out of.4. really good disc-shaped structure helps the even distribution of flying dust in bed, has avoided simultaneously at outlet faying face place because thermal stress is concentrated the cracking that causes.

Five, specific embodiments
The utility model is that a kind of strength is carried with raising nozzle in the end, form by nozzle body 1 and cap of spraying nozzle body 2, cap of spraying nozzle body 2 is located on the nozzle body 1, on nozzle body 1, be provided with charging hole 11 and discharge opening 12, cap of spraying nozzle body 2 is a disc-shape, nozzle body 1 is a column, and the cap of spraying nozzle body 2 of present embodiment is high chromium nickel rare earth alloy cap of spraying nozzle body, and nozzle body 1 is high chromium nickel rare earth alloy nozzle body.Above-mentioned charging hole 11 is the axial admission hole, and discharge opening 12 is discharge opening radially, and discharge opening 12 has 8 and circumferentially evenly distributing along nozzle body in the present embodiment.
