Abstract
The utility model discloses a burning device of a coal powder smelting furnace, which belongs to the technical field of burners, and comprises a main coal powder burner; the rear end of the main coal powder burner is connected with a coal powder delivery pipeline; the coal powder delivery pipeline is connected with a mill; the burning device of the coal powder smelting furnace is characterized in that the coal powder delivery pipeline is connected with a coal powder distributor; the coal powder distributor comprises a coal inlet and two coal outlets, wherein one coal outlet is connected with the coal powder delivery pipeline of the main coal powder burner and the other coal outlet is connected with a powder control valve; and the powder control valve is connected with an auxiliary burner through the coal powder delivery pipeline. Compared with the prior art, the burning device of the coal powder smelting furnace takes raw coal as fuel, has the advantages of high heat efficiency, rapid heating, stable burning and lower fuel cost, and is applicable to a plurality of types of non-ferrous metal smelting furnaces.
Description
Technical field
The utility model belongs to technical field of burner, is specifically related to a kind of coal dust smelting furnace burner.
Background technology
At present, the fuel of nonferrous metal smelting furnace mainly contains coal, coal gas, diesel oil, heavy oil and natural gas.Diesel oil and astatki cost are higher; The application of natural gas is subjected to the restriction of source of the gas supply; The smelting furnace system gas equipment input that with coal gas is fuel is bigger; Traditional is the coal furnace of fuel with lump coal, burn insufficient, the thermal efficiency is low, and slow, the combustion instability of heating up has periodically, add coal in addition and the labour intensity of skimming big.
The utility model content
For solving the above-mentioned defective that prior art exists, it is fuel, thermal efficiency height that the purpose of this utility model provides a kind of raw coal, the coal dust smelting furnace burner of heat up rapid and flameholding and fuel savings cost.
For achieving the above object, the technical solution adopted in the utility model is: this coal dust smelting furnace burner has main pulverized coal burner, the main pulverized coal burner rear end is connected with power transportation pipe, power transportation pipe connects flour mill, it is characterized in that: be connected with pulverized coal distributor on the described power transportation pipe, pulverized coal distributor has a coal feed point and two coal outlets, wherein a coal outlet is connected on the power transportation pipe of main pulverized coal burner, another coal outlet is connected with control powder valve, and control powder valve is connected with auxiliary burner by power transportation pipe.
In the described pulverized coal distributor guide vane is housed.
Described auxiliary burner adopts coal nozzle.
Described main pulverized coal burner adopts no fire in a stove before fuel is added multiple duct coal burner.
Described no fire in a stove before fuel is added multiple duct coal burner bottom is provided with wheel, and wheel is positioned on the track of fixed frame, also is provided with on the no fire in a stove before fuel is added multiple duct coal burner to drive the rotating mechanism that burner hearth rotates.
Adopt the beneficial effect of technique scheme to be: this coal dust smelting furnace burner adopts two coal burner structures, promptly have main pulverized coal burner and auxiliary burner, flour mill by pulverized coal distributor by power transportation pipe respectively to two burner coal supplies, by control powder valve control supply, pulverize after pulverized coal distributor mixes the back is delivered to major and minor burner by power transportation pipe and fire burns by raw coal by pulverized coal distributor for the coal dust of major and minor burner.Guide vane is housed in the pulverized coal distributor, and coal dust is more even by mixed allocation behind the guide vane, thereby has guaranteed the smooth combustion of burner, and thermal efficiency height heats up rapidly.Control powder valve can be controlled the coal dust supply of coal nozzle, makes coal nozzle flameholding and sufficient combustion.Coal dust smelting furnace burner described in the utility model is compared with traditional smelting furnace burner, has thermal efficiency height, heats up rapidly and characteristics such as flameholding, fuel savings cost, is suitable for the application in the multiple nonferrous metal smelting furnace.
Description of drawings:
Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further detail.
Fig. 1 is a general structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of pulverized coal distributor of the present utility model.
The specific embodiment:
Coal dust smelting furnace burner as shown in Figure 1, has main burner 7, main burner 7 is positioned on the fixed frame, corresponding smelting furnace 6 inner chambers of the outlet of main burner 7, the bottom of main burner 7 is provided with wheel, fixed frame is provided with track, the wheel of main burner 7 is positioned on the track of fixed frame, can move forward and backward by wheel, be convenient to scarfing cinder, also be provided with rotating mechanism 8 on the main burner, the burner hearth of main burner can rotate by rotating mechanism 8, avoid the too early scaling loss of burner hearth, prolonged service life, main burner 7 adopts no fire in a stove before fuel is added multiple duct coal burner.Main burner 7 rear ends are connected with power transportation pipe 3, power transportation pipe 3 is a metal hose, power transportation pipe 3 connects a coal outlet of pulverized coal distributor 1, the coal feed point of pulverized coal distributor 1 is connected with flour mill, another coal outlet of pulverized coal distributor 1 is connected with auxiliary burner 4 by power transportation pipe 3, auxiliary burner 4 is a coal nozzle, and blower fan 5 is connected with auxiliary burner 4.As shown in Figure 2, guide vane 9 is housed in the coal feed point of pulverized coal distributor 1, the coal outlet place that pulverized coal distributor 1 is connected with auxiliary burner 4 is provided with control powder valve 2, and by pulverized coal distributor, coal dust fully mixes with air, sufficient combustion and stable, thermal efficiency height.
