Description
Technical field
The utility model relates to burners, replace turbulent burner in particular for a kind of spout of blast funnace hot blast stove.
Background technique
Ceramic burner is applied on blast funnace hot blast stove and is had it long ago, mainly by body, combustion chamber, air duct and coal
Gas channel is constituted, the problem as present on structure, is used and unsatisfactory, although multiplicity there are many ceramic burners,
There is following situations in current various ceramic burners:
(1) mixing of coal gas and combustion air is poor, and excess air is larger, there is unburned CO, excess air in exhaust gas
The raising of amount and uncombusted CO content, reduces the theoretical temperature combustion of fuel, influences hot-blast stove dome temperature and hot blast temperature
Raising, waste of energy, pollute environment；
(2) medium composition distribution is serious uneven, reduces efficiency of combustion and ignition temperature, liner due to uneven heating by
Damage, reduces using effect and the service life of burner；
(3) combustion flame generates " vibration ", especially uses high heating value gas and uses biggish excess air coefficient
When, " vibration " is easier to occur, and seriously affects the service life of hot-blast stove.
Though existing have a kind of burner (high-speed uniformly mixing section of application number 2005200320148 and application number 200920224295
Energy ceramic burner) above problem is overcome, but gas mixing still has unevenness in use, and gas-fired is not fully filled
Point, heat utilization rate is low, and energy waste is big, pollutes environment, therefore, improvement and innovation on burner are still must skill to be solved
Art problem.
Utility model content
For above situation, to overcome the shortcomings of existing technologies, the purpose of the utility model is just to provide a kind of spout friendship
For turbulent burner, it effectively can further solve that gas-fired is not fully abundant, and heat utilization rate is low, energy waste is big, dirty
The problem of contaminating environment.
The technical solution that the utility model solves is a kind of spout alternating turbulent burner, including body, combustion chamber, coal
It is logical in up-down structure to be mounted with gas allocation in the wall of body for gas inlet duct, air inlet duct and gas allocation channel
Road and air distribution channel, gas entry pipeline are connected with gas allocation channel, air inlet duct and air distribution channel
It is connected, equipped with upper and lower alternate two rows of coals of the spouts towards combustion chamber in parallel opened on the inner wall of the combustion chamber at center in body
Gas jets, air nozzle, the gas nozzle, air nozzle alternating on every row are evenly distributed, and gas allocation channel is shunted through coal gas
Pipe is connected with gas nozzle, and air distribution channel is connected through air shunt tube with air nozzle, gas nozzle, air nozzle
Center line and Inner Wall of Combustion Chamber in oblique, i.e., be placed on burner body inner wall in the radiation of rotary-cut shape, constitute spout alternating
Spiral-flow type structure.
The utility model structure is simple, and novel and unique is easy to install and use, and effect is good, is the innovation on burner, has good
Good economic and social benefit.
Detailed description of the invention
Fig. 1 is the cross-section structure main view of the utility model.
Fig. 2 is the A-A of the utility model Fig. 1 to sectional view.
Specific embodiment
It elaborates below in conjunction with attached drawing to specific embodiment of the present utility model.
As shown in Fig. 1, Fig. 2, a kind of spout of the utility model replaces turbulent burner, including body, combustion chamber, coal gas enter
It is logical in up-down structure to be mounted with gas allocation in the wall of body 9 for mouthful pipeline 1, air inlet duct 4 and gas allocation channel 3
Road 3 and air distribution channel 5, gas entry pipeline 1 are connected with gas allocation channel 3, air inlet duct 4 and air distribution
Channel 5 is connected, equipped with the upper and lower alternate parallel spout direction combustion of two rows opened on the inner wall of the combustion chamber 10 at center in body 9
Gas nozzle 8, the air nozzle 7 for burning room, gas nozzle 8, air nozzle 7 on every row replace evenly distributed, and gas allocation is logical
Road 3 is connected through coal gas isocon 2 with gas nozzle 8, and air distribution channel 5 is connected through air shunt tube 6 with air nozzle 7
Logical, it is in that the radiation of rotary-cut shape is placed in burner sheet that gas nozzle 8, the center line of air nozzle 7 and Inner Wall of Combustion Chamber, which are in oblique,
On internal wall, constitutes spout and replace spiral-flow type structure.
In order to guarantee using effect and easy to use, the air distribution channel 5 and gas allocation channel 3 be it is hollow,
Section is rectangular or circular circular passage；
The air nozzle 7, gas nozzle 8 in it is two rows of interlock up and down alternate drive the inner walls mounted in 10 middle part of combustion chamber
On, the air nozzle 7 of upper row and the gas nozzle 8 of upper row are on same upper ring surface, the coal gas of the air nozzle 7 of lower row and lower row
Nozzle 8 is on anchor ring once, and upper and lower two anchor ring is in arranged in parallel；
The gas allocation channel 3 is connected from lower part coal gas isocon 2 with upper and lower two rows of gas nozzle 8；
The air distribution channel 5 is connected from upper air isocon 6 with upper and lower two rows of air nozzle 7.
From the above, it is seen that the air nozzle 7 of the utility model, gas nozzle 8 go to upper and lower two rows and are alternately arranged, and
And be arranged on burner body inner wall in the radiation of rotary-cut shape, ejecting force is strong, is uniformly mixed, and burning is abundant, heat utilization rate
It further increases, through testing, heat utilization rate can be improved 20% or more, energy saving 30% or more, greatly reduce to environment
Pollution, energy conservation and environmental protection are the innovations to existing burner, there is good economic and social benefit.
