Description
Technical field
The present invention relates to a kind of gasification furnace, particularly a kind of gasifier nozzle.
Background technology
Burner is one of critical component of gasification furnace gasification; Its main effect is that fuel and gasifying agent are imported gasification furnace with certain speed; Under the dynamic action of the gasifying agent of high velocity jet, that realizes fuel and gasifying agent fully mixes the unburnt chemical reaction of generation afterwards.Because the operating temperature in the gasification furnace is usually above 1400 ℃; And be under the environment of pressurization; Requirement to burner is very high, if nozzle structure design is improper, will cause that fuel and gasifying agent mixed effect are poor, burner end cooling deficiency; Thermal stress is too high, influences gasification furnace when serious and normally moves.
In the existing Coal Gasification Technology, the scheme comparative maturity with Texaco, Shell, GSP also has their own characteristics each in the design of burner, but the deficiency of self is all arranged:
The Texaco burner: 1. adopt the water-coal-slurry charging, mix the back ejection in internal-mixing structure, the water-coal-slurry hybrid chamber in burner, very serious to the wearing and tearing in the chamber, need often to change wearing terrain (life-span generally has only 30-60 days); 2. the cooling chamber of face and the weld of sidewall water-cooled coil pipe are exposed to side towards the fire before the burner, under the continuous action of long-time thermal stress, damage in advance easily; 3. water-cooled coil pipe side is advanced the structure that side goes out, and makes that possibly there is situation pockety in the media flow in the preceding face cooling chamber of burner.
Shell burner: 1. be designed with the polylith screw stops in the water-cooling channel of face and sidewall before the burner; Complex structure; The manufacturing difficulty of processing is big, and especially preceding face and block need use the machine-shaping of monoblock steel alloy, cause back closed guard welding sequence complicated; Machining stress is concentrated, and is easy to generate defective; 2. complicated Channel Design causes the resistance of cooling agent to increase, and it is big that pressure drop becomes;
The GSP burner: 1. light a fire and the function that goes into operation concentrates on the combined type burner, the quantity of fuel and water-cooling channel is more, is unfavorable for maintenance and changes; 2. coal dust adopts rotation to broadcast the coal mode to send into, and gasifying agent outlet simultaneously also has certain eddy flow, causes the speed of both axial directions to weaken to some extent, and the gasification furnace type of furnace that is confined to the single injector overhead is used.
Therefore above-mentioned burner in use all can not satisfy the demands, and needs a kind of simple and effective burner, can guarantee simple in structurely, and can cool off the preceding face of burner effectively.
Summary of the invention
Goal of the invention of the present invention is: the problem to above-mentioned existence, provide a kind of simple in structure, and to make, install and the maintenance more convenient and quicker, preceding face is big to the cooling water disturbance, the gasifier nozzle of the good cooling results of preceding face.
The technical scheme that the present invention adopts is following:
Gasifier nozzle of the present invention; Comprise burner body; Have cooling-water duct in the said burner body, the front end of said burner body is provided with preceding face, and preceding face seals up cooling-water duct; Be provided with baffle plate in the cooling-water duct of said burner body front end, form how rotating water-cooling channel or single rotating water-cooling channel before making between face inboard and the baffle plate.
Owing to adopted said structure; Through in the cooling-water duct of burner body front end, being provided with baffle plate; Form reverse how rotating water-cooling channel or single rotating water-cooling channel before making between face inboard and the baffle plate; Cooling water fully contacts with preceding face is inboard in this how rotating water-cooling channel or single rotating water-cooling channel, better preceding face is cooled off, and makes the good cooling results of whole burner.And be somebody's turn to do how rotating or single rotating water-cooling channel, simple in structure, manufacturing, easy to installation and maintenance quick.
Gasifier nozzle of the present invention offers the outlet of water-cooled import and water-cooled on the said baffle plate, the rotating water-cooling channel of said list mainly is through between preceding face inboard and baffle plate, dividing plate being set, water-cooled import (8) and water-cooled outlet being separated formation.
Owing to adopted said structure; Through in the cooling-water duct of burner body front end, being provided with baffle plate; Water-cooled import on the baffle plate and water-cooled outlet are separated by dividing plate, and between preceding face inboard and baffle plate, form single rotating water-cooling channel, and cooling water fully contacts with preceding face is inboard in this single rotating water-cooling channel; Guarantee the uniformity of side contacts in cooling water and the preceding face, made the good cooling results of whole burner.In use, in the water-cooling channel before cooling water can enter into from the water-cooled import between face inboard and the baffle plate, along passage and preceding face are inboard fully contact after, export from water-cooled and to flow back in the cooling-water duct, preceding face is effectively cooled off.Face and dividing plate are made up of solderless high temperature alloy thin-walled before the burner; Simple in structure, the back baffle plate manufacturing that is mated is simple, and welding capacity is little; The size of face does not receive the spatial constraints of dividing plate and lateral wall before the burner; Can be designed to reduce the area of side towards the fire, guarantee under the situation of equal cooling water inflow better cooling effect than face structure before the cooling of minor diameter.Since adopt the rotating water-cooling channel of above-mentioned list, and be somebody's turn to do single rotating water-cooling channel, simple in structure, dependable performance, manufacturing, easy to installation and maintenance quick.
Gasifier nozzle of the present invention; Said how rotating water-cooling channel mainly is to form through toroidal membrane, dividing plate and central dividing plate are set between preceding face inboard and baffle plate, wherein offers the outlet of water-cooled import and water-cooled on the baffle plate, and said water-cooled import and water-cooled outlet are separated by dividing plate; Offer breach on the said toroidal membrane; This breach is away from the outlet of water-cooled import and water-cooled, and said central dividing plate and separates the two ends of breach between the two ends of breach.
Owing to adopted said structure; Before being installed in through toroidal membrane, dividing plate and central dividing plate sealing between face inboard and the baffle plate, forms and reverse revolve water-cooling channel more, make cooling water to enter between preceding face inboard and the baffle plate from the water-cooled import; Promptly enter between the outer wall and toroidal membrane of cooling-water duct; Breach one end from toroidal membrane enters between the inwall of toroidal membrane and cooling-water duct again, around the inwall of whole cooling-water duct, enters between the outer wall and toroidal membrane of cooling-water duct from the breach other end of shape dividing plate; Flow back in the cooling-water duct from the water-cooled outlet, preceding face is effectively cooled off.Owing to adopted above-mentioned how rotating water-cooling channel; Make cooling water between preceding face and baffle plate, form the reverse water circulation in two weeks; Thereby increase the time of staying of cooling water between preceding face and baffle plate; Increase cooling water and inboard the contacting of preceding face, increase the disturbance of cooling water, make cooling effect better.
