Description
One, technical field
The utility model relates to hotblast stove, particularly a kind of novel top combustion stove.
Two, background technology
Now in the hotblast stove that blast furnace ironmaking uses, the top combustion stove of sleeve combustion system still accounts for very big ratio, the top combustion stove of sleeve combustion system begins one's study from the seventies in last century and invents and apply, because the problem that exists on the structure, adopt the coal gas and the air of the top combustion stove of sleeve combustion system not to be mixed fully, to such an extent as to energy consumption is big, efficient is low, wind-warm syndrome is low, and making improvements and innovating is the problem of needing solution badly.
Three, utility model content
At above-mentioned situation, for solving the defective of prior art, the purpose of the utility model just provides a kind of novel top combustion stove, can effectively solve hotblast stove gas mixes bad, the energy consumption height, low and the low problem of wind-warm syndrome of efficient, the technical scheme of its solution is, comprise vault, combustion chamber and body of heater, the vault bottom is the combustion chamber, coal gas circuit and air circuit are arranged in the body of wall of combustion chamber, coal gas circuit bottom and air circuit top have respectively and are circumferentially uniform gasburner and air nozzle, the cross section of gasburner and air nozzle is horizontal by certain included angle, the hybrid channel is arranged in combustion chamber wall in the middle of coal gas circuit and the air circuit, the hybrid channel is connected with gasburner and air nozzle, the burner port that is connected with the hybrid channel level is arranged on the combustion chamber, the gas entry and the gas inlet that are connected with coal gas circuit and air circuit are respectively arranged on the outer wall of combustion chamber, hot-blast outlet is arranged on the outer wall of combustion chamber, regenerator is arranged at the bottom, combustion chamber, the combustion chamber wall bottom links to each other with regenerator wall top through the labyrinth type linker, regenerator wall bottom links to each other with upper of furnace body through the labyrinth type linker, simple in structure, result of use is good, is the innovation on the hotblast stove.
Four, description of drawings
Accompanying drawing is a main pseudosection of the present utility model.
Five, embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Provide by accompanying drawing, the utility model comprises vault, combustion chamber and body of heater, vault 1 bottom is combustion chamber 2, coal gas circuit 3 and air circuit 6 are arranged in 2 bodies of wall of combustion chamber, coal gas circuit bottom and air circuit top have respectively and are circumferentially uniform gasburner 4 and air nozzle 5, the cross section of gasburner and air nozzle is horizontal by certain included angle, hybrid channel 7 is arranged in combustion chamber wall in the middle of coal gas circuit and the air circuit, hybrid channel 7 is connected with gasburner and air nozzle, the burner port 10 that is connected with hybrid channel 7 levels is arranged on the combustion chamber, the gas entry 8 and the gas inlet 9 that are connected with coal gas circuit and air circuit are respectively arranged on 2 outer walls of combustion chamber, hot-blast outlet 11 is arranged on the outer wall of combustion chamber, regenerator 13 is arranged at the bottom, combustion chamber, the combustion chamber wall bottom links to each other with regenerator wall top through the labyrinth type linker, and regenerator wall bottom links to each other with body of heater 15 tops through the labyrinth type linker.
In order to guarantee result of use, said gasburner and air nozzle are staggered, gasburner is positioned at the top of hybrid channel, air nozzle is positioned at the below of hybrid channel, coal gas and air are mixed from oblique being pooled in the hybrid channel in both sides up and down of hybrid channel, reach well-mixed effect.
The rectangular channel structure that said coal gas circuit 3 and air circuit 6 progressively reduce along gas flow direction for sectional area.
The angle of said regenerator 13 inwalls and base plane is 60 °.
The utility model reasonable integral structure, because the combustion chamber is in the space of a sealing, its interior combustion of mixed gas thermostability is improved greatly, solved the problem that telescopic in the past hotblast stove open type burner exists, improved its work-ing life greatly, owing to adopt the nozzle of annular staggered arrangement and the hybrid channel that is used with nozzle, can make coal gas and air realize quick premix, combustion of mixed gas efficient is improved, solved in the past and the incendiary phenomenon occurred in the mixed gas incomplete combustion and ball bed heat storage, refractory ball distortion and bonding problem have fundamentally been solved, prolong the life-span of refractory ball, mixed gas sprays into the combustion chamber through the hybrid channel through burner port, make the top-down combustion chamber internal combustion that enters of mixed gas, air-flow is steady, for the heat exchange between combustion chamber and the regenerator provides condition, can make the heat storage in the regenerator obtain full and uniform heating, thereby improve wind-warm syndrome and efficiency of combustion, by adopting the labyrinth type linker, the body of heater intensity of hotblast stove is improved, prolongs the work-ing life of body of heater.
The utility model structure uniqueness, easy to use, coal gas and air mixed evenly, sufficient combustion, flue gas flow field is evenly distributed, the efficient height, the life-span is long, wind-warm syndrome is high, has remarkable economical and social benefit.
