Abstract
The utility model discloses a heat storage stable-combustion device of a blast furnace gas diffusing tower. The heat storage stable-combustion device comprises a shell arranged on the top of a combustor and communicated with the combustor. Heat storage materials are fixed inside the shell which is in a circular platform shape, and the shell is 1 meter high and is a stainless steel shell. When the diffusing tower is in a normal combustion state, the temperature of the heat storage materials in the shell becomes high, the temperature of the heat storage materials can be more than 800 DEG C through heat storage and heat release. When the diffusing amount of the diffusing tower is increased and exceeds the original combustion diffusing capability, namely, when flamelifting happens and gas flows inside the shell, the heat inside the shell can enable the gas to burn continuously, the stable-combustion effect is achieved, and the combustion diffusing ability of the diffusing tower is enhanced. After the combustion effect is improved, an original diffusing tower can be ignited, and a companying gas source is changed into blast furnace gas from converter gas. The flamelifting phenomenon does not happen easily in the gas diffusing tower, the gas can normally and stably burn and diffuse, and safety threat to surrounding people is reduced.
Description
Technical field
The utility model belongs to blast-furnace gas diffusing tower burner field, is specifically related to a kind of blast-furnace gas diffusing tower heat storage and flame stabilization device.
Background technology
At present, iron and steel enterprise's coal gas diffusion tower structure used mostly is installs a main burner at exhaust stack top, and burner inside is generally provided with cyclone, thereby by cyclone, coal gas and air mixing is reached to clean-burning effect.Yet, by the burning ability of diffusing of this combustion system of practical proof, be very limited, it is bad that effect is diffused in the burning of coal gas diffusion tower, when coal gas diffusion amount is larger, easily occurs de-fiery phenomenon.
Utility model content
The purpose of this utility model is to provide a kind of blast-furnace gas diffusing tower heat storage and flame stabilization device, and it has solved the burning of coal gas diffusion tower and has diffused that ability is little, easily de-fire causes the problem of potential safety hazard.
For achieving the above object, the utility model adopts following technical scheme:
The utility model comprises and is arranged on the housing that burner top and burner are connected, fixing heat-storing material in housing.
Described housing is circular platform type.
The height of described housing is 1 meter.
Described housing is Stainless Steel Shell.
In described housing, be provided for the fixedly support of heat-storing material.
Described hull outside arranges a rain cover.
Described rain cover is stainless steel rain cover.
With respect to prior art, the beneficial effect the utlity model has:
The utility model is by the housing arranging at burner top and burner is connected, the interior fixedly heat-storing material of housing, during diffusing tower normal combustion, heat-storing material temperature in housing is raise, housing is interior by the accumulation of heat of heat-storing material, heat release, make heat-storing material reach 800 ℃ above (being greater than the ignition point of blast furnace gas), when the increase of the diffusing tower amount of diffusing is diffused ability over original burning, while being about to occur de-fire, Gas Flow is in housing time, heat in housing can keep coal gas to burn away, thereby reach steady fuel efficiency fruit, and increase diffusing tower burning and diffuse ability.After combustion efficiency is improved, former diffusing tower igniting, companion can be burnt to source of the gas and change blast furnace gas into by coal gas of converter.Coal gas diffusion tower of the present utility model is not easy to occur de-fiery phenomenon, stablizes coal gas normal combustion and diffuses, and reduces personnel's security threat around.
Further, housing is circular platform type, so that the coal gas in the housing of flowing through fully contacts with heat-storing material, guarantees abundant burning.Housing is used stainless steel.Rainwater makes the heat-storing material explosion of catching a cold when preventing from raining, and increases a rain cover storage heater is outside, to whole housing and heat-storing material, can play a protective role.
The utility model, because combustion efficiency improves, can be used blast furnace gas to light a fire, accompany burning.Having overcome in prior art the burning of coal gas diffusion tower, to diffuse effect bad, uses coal gas of converter to light a fire, accompany burning, could ensure the problem that the normal combustion of relatively large blast furnace gas is diffused.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein, 1 is rain cover, and 2 is heat-storing material, and 3 is housing, and 4 is burner, and 5 is blast furnace gas supervisor net, and 6 is electric butterfly valve, and 7 is electronic blank-plate valve, and 8 is manhole, and 9 is control valve.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
Referring to Fig. 1, the utility model comprises the housing 3 that is arranged on the circular platform type that burner 4 tops and burner 4 be connected, and housing 3 is Stainless Steel Shell.In housing 3, be provided with support, fixing heat-storing material 2 on support.Heat-storing material in housing 3 is saved heat, is stablized the burning of coal gas diffusion tower, reduces the de-fiery phenomenon of gas-fired; Heat-storing material adopts honeycomb ceramic body, and concrete material is aluminium oxide, and cellular heat-storing material has advantages of that heating surface is large, heat storage efficiency is high, can save heat, stablize the burning of coal gas diffusion tower, reduces the de-fiery phenomenon of gas-fired.
The height of the housing in the utility model is 1 meter, for increasing the height of the heating surface housing of regenerative apparatus, should suitably increase, whole housing setting height(from bottom) should be determined the middle part of the maximum height of normal combustion flame in the prior art, and not coal gas of the upper and lower two parts of housing is beneficial to ignite.According to the diameter of diffusing tower exhaust stack the choice of diameter housing.
For guaranteeing the normal accumulation of heat of regenerative apparatus, prevent that rainwater from affecting it, cause the heat-storing material explosion of catching a cold, should a rain cover 1 with regenerative apparatus housing 3 structural similarities be installed regenerative apparatus housing 3 is outside, rain cover 1 is selected stainless steel.
During work, the coal gas in blast furnace gas supervisor net 5 enters in burner 4 after electric butterfly valve 6, electronic blank-plate valve 7, control valve 9, and then enters in housing 3.
Caliber in blast furnace gas supervisor net 5 is DN900, and purging valve is set on manhole 8.
The utlity model has following advantage:
(1) coal gas diffusion tower of the present utility model is not easy to occur de-fiery phenomenon, stablizes coal gas normal combustion and diffuses, and reduces personnel's security threat around;
(2) after combustion efficiency is improved, former diffusing tower igniting, companion can be burnt to source of the gas and change blast furnace gas into by coal gas of converter, and the utility model can increase diffusing tower burning and diffuses ability.
