Abstract
The utility model relates to an igniter for a sintering machine. The utility model comprises a system making coal powder and supplying the coal powder, a gas supply system, combustion wind system, a plurality of combustion nozzles and an igniter body. The system making the coal powder and supplying the coal powder is composed of a coal feeding machine, a fan coal miller, a pressurization fan, a dispenser, a coal powder conveying pipeline and a valve; the coal supply system is composed of a gas pipeline, a gas branch pipe and the valve; besides, the utility model is provided with a plurality of combustion nozzles, and each combustion nozzle is communicated with the coal powder conveying pipeline, the gas branch pipe and a combustion wind conveying pipeline. The igniter for the sintering machine can make the combustion of the coal powder as well as the gas, or making use of the two parties simultaneously. The igniter for the sintering machine has the advantages of uniform ignition, high heat efficiency and board fuel application.
Description
The utility model belongs to the servicing unit of powder sintering agglomeration equipment.Mainly be applicable to the igniting of sintering machine sinter mixtures such as Iron Ore Powder, non-ferrous metal breeze and building porcelain granule.
Sintering machine is a kind of fine ore, powder sintering agglomeration equipment.It is made up of igniter, mobile chain belt chassis, exhausting bellows etc.The powder that needs agglomeration mixes with coke powder by a certain percentage, after the granulation, is taped against on the sintering pallet by certain thickness.By the thermal-flame district of igniter bottom, light the coke powder in the sinter mixture.Chassis constantly moves forward immediately, shifts out igniter, relies on the wind chamber exhausting, and the coke powder in the compound burns away, and the powder sintering that needs sintering is become block, reaches the purpose of powder agglomeration.
The difference of ignition of sintering process device (being igniter) based on fuel resource can be used gaseous state, liquid state or solid fuel.Existing igniter can only be used single fuel, coal dust or coal gas.
The ignition of sintering process device is made up of two parts: the one, make powder and coal supply powder system; The 2nd, the igniter body.Existing pulverized coal ignition device (" agglomerates of sintered pellets " 1989 the 1st phases, 26～29 pages), the technological process and the equipment complexity of system coal dust and coal supply powder system, investment is high, inconvenient operation, and have only a coal dust to burn and chew, it is inhomogeneous to light a fire, and the thermal efficiency is low; This igniter can only be fuel with the anchracite duff.
It can be the ignition of sintering process device of fuel combination with coal dust and coal gas again with coal dust or coal gas single-fuel simultaneously that the purpose of this utility model is to provide a kind of.
In order to achieve the above object, the utility model is chewed igniter and is formed by system coal dust and coal supply powder system, the system that gives gas, combustion air system, burn more.System coal dust and coal supply powder system are made up of feeder, blower mill, booster fan, pulverized coal distributor, coal dust transfer pipeline and valve; The system that gives gas is made up of gas piping, branch gas tube and valve; The combustion air system is made up of combustion fan, combustion air transfer pipeline and valve.In order to light a fire evenly, improve the thermal efficiency, the comprehensive utilization energy, the utility model adopt burn to chew igniter more, promptly burn and chew number〉3, and the igniter burner hearth is short; In addition, except the coal supply powder system, also added the system of giving gas, promptly chewed, can supply coal dust or coal gas respectively a burning.In addition, each burning is chewed also and need be passed to combustion air.
Compared with prior art, advantage of the present utility model:
1. owing to use a plurality of burnings to chew, can make igniting or insulation more even, the igniter burner hearth is short, thermal efficiency height.
2. fuel can use coal dust or coal gas, or both use simultaneously, and applicability is strong, and purposes is wide.
3. it is simple to make the pulverized coal system flow process, and small investment is easy to operate.
Now the utility model is described in further detail in conjunction with the accompanying drawings.
Accompanying drawing is the structural representation of the utility model ignition of sintering process device.
Among the figure, 1 is blower mill, and 2 is feeder, 3 is booster fan, and 4 is pulverized coal distributor, and 5 is to burn to chew, 6 is igniter body (burner hearth), 7 is the coal dust transfer pipeline, and 8 is that buncher, 9 is valve, and 10 is combustion fan, 11 is gas piping, 12 is branch gas tube, and 13 is the combustion air transfer pipeline, and 14 is chassis.
Shouting is chewed to a plurality of burnings and is chewed (burning is chewed number〉3), is installed in the top of igniter body, and each burning is chewed with the coal dust transfer pipeline and the arm that gives gas and communicated.A plurality of burnings are chewed and can be in line or line up multirow.
Quantitatively feeder can be supplied with the coal pulverizer raw coal quantitatively according to firing temperature.But the blower mill that adopts is coal-grinding both, and the power of pulverized coal conveying can be provided again.Pulverized coal distributor can be supplied with each burning equably with coal dust and chew.
The course of work of the present utility model is as follows:
System coal dust and coal supply powder system: raw coal is delivered to blower mill 1 quantitatively through feeder 2, after grinding, coal dust blows out coal pulverizer after booster fan 3 pressurizations, enter pulverized coal distributor 4, deliver to burn by coal dust transfer pipeline 7 through the coal dust of uniform distribution and chew 5, then in igniter 6 internal combustion.
System gives gas: coal gas is delivered to each burning by gas pipeline 11 through branch gas tube 12 and is chewed.
Each burning is chewed and also is input into the combustion air of being carried by combustion air transfer pipeline 13 simultaneously, is beneficial to full combustion of fuel.
The utility model igniter based on fuel supply situation, all burnings are chewed all firing coal dust or all burnings and are chewed all and burn gas; Also can part burning chew firing coal dust, a part is burnt to chew and is burned gas.
Claims (2)
1, a kind of ignition of sintering process device, comprise raw coal disintegrating apparatus, coal conveyor, booster fan, coal dust transfer pipeline, burn chew, igniter body and combustion-supporting pipeline, it is characterized in that:
(1) igniter adopts a plurality of burnings to chew, and promptly burns and chews number＞3;
(2) but adopted both coal-grindings, the blower mill of power is provided for pulverized coal conveying again;
(3) except the coal supply powder system, also added the system of giving gas, promptly chew a burning, can supply coal dust or coal gas respectively.
2, device according to claim 1, it is characterized in that a plurality of burnings chew can be in line or line up two the row more than.
