Description

A kind of self-priming burner
Technical field
The present invention relates to a kind of burner that can be applicable to steel/iron bag baking and metallurgical equipment baking field, be specially a kind of self-priming burner.
Background technology
The baking of steel/iron bag is one important procedure between these two main production processes of steelmaking and continuous casting, steel/steel for the iron bag/iron bag roaster is toasted so that steel/iron bag temperature to the requirement that meets casting process.Existing steel/iron bag roaster often adopts the gas that act as a fuel such as blast furnace gas, coal gas of converter, and fuel gas is delivered to burner and is mixed with the air come from the outside and realize burning through pipeline.Roaster needs external air-blast device to increase the flow of air to meet the abundant burning of fuel gas, fuel gas pipeline and air pipe line are generally to arrange separately respectively in addition, cause so existing roaster equipment self structure complexity, energy consumption to reach greatly the shortcomings such as maintenance and installation inconvenience.
Summary of the invention
Purpose of the present invention just is to provide a kind of self-priming burner that is applied to steel/iron bag roaster, blower fan and the relevant apparatus that can replace existing roaster, and the fuel gas required air that fully burns can be provided, solve that existing roaster device structure is complicated, large problem consumes energy.
To achieve these goals, technical scheme of the present invention is: a kind of self-priming burner, comprise the outer air pipe be set-located successively from outside to inside, inner air pipe and fuel gas pipe, the outer wall of the inlet end of outer air pipe and inner air pipe is tightly connected, and be provided with the first air intlet on the tube wall of this inlet end, the inlet end of inner air pipe and the outer wall of fuel gas pipe are tightly connected, and be provided with the second air intlet on the tube wall of this inlet end, the gas outlet of described inner air pipe is in the outer air pipe, the gas outlet of fuel gas pipe is in the inner air pipe, the gas outlet of described fuel gas pipe is provided with the first variable-diameter spray head, the bore of the first variable-diameter spray head entrance point is greater than the bore of the port of export, and entrance point is connected by curved surface with the port of export, the gas outlet of described outer air pipe is provided with the second variable-diameter spray head that bore diminishes gradually.
The entrance point of described the second variable-diameter spray head is concordant with the gas outlet of inner air pipe.
Beneficial effect: the present invention is by the setting that is set-located of fuel gas pipe and two-way air hose, and one variable-diameter spray head is set by fuel gas acceleration outflow by the gas outlet at fuel gas pipe, thereby the air that can take away in the inner air pipe flows out at a high speed, form like this air intake of vacuum in impelling atmosphere to the inner air pipe in the inner air pipe, after accelerating, another variable-diameter spray head that mixed fuel gas-air arranges through outer air pipe gas outlet sprays at a high speed and the ignition combustion roasting plant, at the same time, and the air of taking away in the outer air pipe flows out at a high speed, making in the outer air pipe to form vacuum impels the air intake in atmosphere to arrive in the outer air pipe, the air sucked in the outer air pipe mixes with fuel gas-air again at its place, gas outlet, thereby realize that double suction enters two combustion modes of supplying gas of mixing.
The present invention relies on a part of pressure energy of consume fuel gas to realize the kinetic force that certainly sucks and be converted into air of air, it can realize two the mixing with fuel gas, thereby for the abundant burning of fuel gas provides sufficient oxygen, blower fan and the relevant apparatus that can replace existing roaster, existing roaster device structure is simplified, greatly reduced the energy consumption of equipment simultaneously, take the baking 100t steel/the iron bag is example, with main flow equipment on present market, compare, the present invention can save production cost more than 20%, saves the energy 35% left and right.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The cross-sectional view that Fig. 2 is the first variable-diameter spray head.
The cross-sectional view that Fig. 3 is the second variable-diameter spray head.
In figure, be labeled as: 1, inner air pipe, 2, fuel gas pipe, 3, the outer air pipe, the 4, first variable-diameter spray head, the 5, second variable-diameter spray head, the 6, first air intlet, the 7, second air intlet, 8, sealing plate, 9, flange, 10, fixed head.
The specific embodiment
As shown in Figure 1, a kind of self-priming burner, comprise the outer air pipe 3 be set-located successively from outside to inside, inner air pipe 1 and fuel gas pipe 2, the outer wall of the inlet end of outer air pipe 3 and inner air pipe 1 is tightly connected, and be provided with the first air intlet 6 on the tube wall of this inlet end, the outer wall of the inlet end of inner air pipe 1 and fuel gas pipe 2 is tightly connected, and be provided with the second air intlet 7 on the tube wall of this inlet end, the gas outlet of described inner air pipe 1 is in outer air pipe 3, the gas outlet of fuel gas pipe 2 is in inner air pipe 1, the gas outlet of described fuel gas pipe 2 is provided with the first variable-diameter spray head 4, the bore of the first variable-diameter spray head 4 entrance points is greater than the bore of the port of export, and entrance point is connected by curved surface with the port of export, the gas outlet of described outer air pipe 3 is provided with the second variable-diameter spray head 5 that bore diminishes gradually.Wherein, between the outer wall of the inlet end of outer air pipe 3 and inner air pipe 1, can be tightly connected by flange 9, can be tightly connected by sealing plate 8 between the outer wall of the inlet end of inner air pipe 1 and fuel gas pipe 2, on the outer wall of outer air pipe 3, can also be provided with fixed head 10.
