Description
Technical field
The utility model relates to a kind of hot-blast stove, especially a kind of full steel structure fuel-firing gas-firing hot-blast stove.
Background technology
Current, hot-blast stove is widely used in the thermal technology of multiple industry, and hot-blast stove has body of heater, burner is equipped with in the side of body of heater, furnace interior is divided into combustion chamber and mixing chamber two parts, and combustion chamber is generally steel cylinder structure, and inner lining refractory block structure is built by laying bricks or stones by scene and formed.Hot-blast stove operationally, fuel by burner in combustion chamber combustion, the high-temperature gas that burning produces mixes with cold air in mixing chamber, thus obtain meeting technological requirement (existing technological requirement, hot-blast stove the flue-gas temperature of confession be less than or much smaller than the ignition temperature in combustion chamber) heat smoke.
But, in order to reach technological requirement, guarantee that high-temperature flue gas mixes with the full and uniform of cold air, the size of required mixing chamber is larger, thus causes the volume of whole body of heater to increase, and the inner lining refractory block of building by laying bricks or stones needed for burner hearth inside increases greatly, so not only increase the weight of body of heater, increase cost of investment, and increase the mobile difficulty of body of heater, cause the thermal inertia of body of heater to strengthen simultaneously.
Summary of the invention
The purpose of this utility model is exactly to solve that current hot-blast stove volume is large, Heavy Weight, thermal inertia are large and cost of investment is high and be not easy to mobile problem of installing, and provides a kind of full steel structure fuel-firing gas-firing hot-blast stove for this reason.
Concrete scheme of the present utility model is: a kind of full steel structure fuel-firing gas-firing hot-blast stove, there is the body of heater of lateral arrangement, the left side of body of heater is provided with burner, it is characterized in that: body of heater is divided into external furnace body and inner furnace body, wherein inner furnace body is sleeved in external furnace body, and vented cavity is formed between inner furnace body and external furnace body, described external furnace body is made up of front side steel cylinder and rear side steel casing, described inner furnace body is set with successively by the steel conical ring of several pre-small post-large layouts and forms, and the gap left between adjacent two conical rings for ventilating, the rear end of inner furnace body is enclosed construction, described burner is arranged on the casing on rear side of external furnace body, and the burner of burner extend into forward in inner furnace body through the blind end of inner furnace body, casing upper end on rear side of described external furnace body is provided with the ventilating opening entered for cold air.
Casing upper end on rear side of external furnace body described in the utility model is provided with the control valve for regulating cold air inlet.
The burner of the cylinder on front side of external furnace body described in the utility model and the conical ring of inner furnace body and burner is arranged on same axis.
The scope of the α of conical ring described in the utility model is 10 °-60 °.
In the utility model, be arranged on described inner furnace body conical ring foremost and be evenly equipped with the circle passage corresponding with axis.
The utility model improves existing hot-blast stove, by the inner furnace body adopting several steel conical rings to be set with composition successively, reach the object that the heat smoke that produces fuel combustion is lowered the temperature step by step, improve the cooling effectiveness of heat smoke, not only reduce the volume of body of heater, reduce cost of investment, and reduce the weight (weight of improvement rear furnace body is the 1/5-1/15 of former body of heater) of body of heater, facilitate the installation of body of heater, movement, meanwhile, reduce the thermal inertia of body of heater.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-burner, 2-vented cavity, 3-cylinder, 4-casing, 5-conical ring, 6-ventilating opening, 7-control valve, 8-passage, 9-fixed support.
Detailed description of the invention
See Fig. 1, the utility model is installed on fixed support 9, there is the body of heater of lateral arrangement, the left side of body of heater is provided with burner 1, body of heater is divided into external furnace body and inner furnace body, wherein inner furnace body is sleeved in external furnace body, and between inner furnace body and external furnace body, form vented cavity 2, described external furnace body is made up of front side steel cylinder 3 and rear side steel casing 4, described inner furnace body is set with successively by the steel conical ring 5 of several pre-small post-large layouts and forms, and the gap left between adjacent two conical rings 5 for ventilating, the rear end of inner furnace body is enclosed construction, described burner 1 is arranged on the casing 4 on rear side of external furnace body, and the burner of burner 1 extend into forward in inner furnace body through the blind end of inner furnace body, casing 4 upper end on rear side of described external furnace body is provided with the ventilating opening 6 entered for cold air.
Casing 4 upper end on rear side of external furnace body described in the present embodiment is provided with the control valve 7 for regulating cold air inlet.
The burner of the cylinder 3 on front side of external furnace body described in the present embodiment and the conical ring 5 of inner furnace body and burner 1 is arranged on same axis.
The scope of the cone angle alpha of conical ring 5 described in the present embodiment is 10 °-60 °, and conical ring 5 adopts the steel of unlike material to make according to different operating temperatures.
In the present embodiment, be arranged on described inner furnace body conical ring 5 foremost and be evenly equipped with the circle passage corresponding with axis 8.
See Fig. 1, in the present embodiment, cool ambient air enters into vented cavity 2 from the ventilating opening 6 of casing 4 upper end be arranged on rear side of external furnace body, wherein control valve 7 is for regulating cold air inlet, cold air is under the promotion of air pressure, move forward in vented cavity 2, and enter into inner furnace body through adjacent two conical rings 5 for the gap ventilated successively, thus the heat smoke produced that burns in inner furnace body is successively lowered the temperature, meanwhile, cold air advance to vented cavity 2 foremost after, further lowered the temperature by passage 8 pairs of heat smoke that inner furnace body conical ring 5 is foremost circular layout, thus improve the cooling effectiveness of heat smoke, reduce the volume and weight of body of heater.
