Description
Technical field
The utility model relates to a kind of companions of blast-furnace gas diffusing tower to burn igniter.
Background technique
The waste emission that blast-furnace gas diffusing tower is used to generate in steelmaking process is into atmosphere.Blast furnace gas includes an oxygen
Change the toxic gases such as carbon, in order to reduce the murder by poisoning that air pollution prevents toxic gas to resident, usually release blast furnace gas it
Before require to burn.Heat is generated since carbon dioxide, the nitrogen in blast furnace gas are not involved in burning, can not be helped
Combustion causes the theoretical temperature combustion of blast furnace gas relatively low on the contrary, also absorbing the heat largely generated in combustion.Cause
The burning of this blast furnace gas is needed using coke-stove gas as burning gas for igniting.
When existing companion's burning igniter is heavy rain, strong wind weather, it can make for the kept burning day and night of the blast furnace gas that ignites
Fire extinguishes, so that toxic gas, which is discharged into atmosphere, causes serious pollution.
Utility model content
In view of this, the present invention provides a kind of blast-furnace gas diffusing towers with burning igniter, flameholding, flame
Temperature is high.
In order to solve the above technical problems, a kind of the technical solution of the utility model are as follows: blast-furnace gas diffusing tower companion burning igniting
Device, including cylindric wind mixed chamber, the wind mixed chamber front end is connected with combustion tube;The wind mixed chamber rear end is connected with coke-oven coal

It manages, is provided with igniter in the ignitron.
As an improvement the air intake duct and coke-stove gas air inlet pipe are in 90 ° of angles.Orthogonal air inlet energy
Eddy flow is formed in wind mixed chamber, so that air mixes more uniform with coke-stove gas.The air inlet of spiral-flow type to burn simultaneously
Thin layer jet-flow is formed in pipe, the air jet of the two sides intra-office annular of each layer of annular fuel gas jet stream improves igniting dress
Institute's jet flames length is set, so that the blast furnace gas in diffusing tower main burner is easier to be ignited.
As an improvement being provided with regulating valve in the air intake duct and coke-stove gas air inlet pipe.For controlling
The air inlet of air and coke-stove gas.
As a preference, the combustion tube front end is provided with necking.Necking designs the pressure for improving jet-impingement, makes
The flame temperature that must be sprayed is higher.
As an improvement being provided with heat storing and heat preserving layer on the combustion tube, the heat storing and heat preserving layer is sandwich, folder
Filling in layer cavity has air;The interlayer is separated into several independent small cavitys using partition.The accumulation of heat of similar Omasum formula
Insulating layer design can maintain temperature required for low calorie fuels.
As a preference, the ignitron and combustion tube utilize casing connection, igniter extends into igniting using casing
In pipe.Facilitate setting and effective protection igniter.
As an improvement further including the flame detector for extending into ignitron using casing.Flame detector and air
Regulating valve cooperating in air inlet pipe and coke-stove gas air inlet pipe, when monitoring to close at once in ignitron without flame combustion
Close air intake duct and coke-stove gas air inlet pipe.
The blast-furnace gas diffusing tower companion having the beneficial effect that with above structure of the utility model burns igniter,
Flameholding, and the flame temperature ejected is high, and length is long, is conducive to lighting for blast furnace gas.Solves existing igniting dress
It is insufficient to set burning, easy the problem of extinguishing.
