Description
Technical field
The invention belongs to the technical field of smelting of copper, and in particular to a kind of vibration premixed type concentrate burner.
Background technology
It is that concentrate burner and the technique for blasting technique wind are set at the top of smelting furnace in the Flash Smelting Furnace smelting technology of copper
Bellows spray into copper concentrate mineral aggregate, oxygen and dispersion wind, in the bottom of concentrate burner, ore deposit by concentrate burner into smelting furnace
Material is mixed with technique wind and ignition forms clinker and matte, and mineral aggregate is sufficiently mixed with the realization of technique wind, this is mineral aggregate in essence
One of rapid, complete oxidation essential condition is carried out in the limited space in ore deposit nozzle lower part.
At present, the concentrate burner that copper mine enterprise uses is expanded by the center that Outokumpu company designs and produces mostly
Type concentrate burner is dissipated, as shown in Figure 1, being that mineral aggregate and technique wind are sprayed into stove in the same direction the characteristics of concentrate burner, mainly passes through gas phase
Achieve the purpose that mixing with the counterdiffusion of solid phase phase, infiltration, when carrying out low level material spray using this central diffused concentrate burner,
That is the entrance of mineral aggregate close to technique wind export when, mineral aggregate is easier to mix with technique wind, but in high-order material spray, also just say
The entrance of mineral aggregate is higher, when still having certain difference in height with the outlet of technique wind, mineral aggregate reaction time relative delay at this time, separately
Outside, when the input amount of mineral aggregate is less, enter stove mineral aggregate rapidly can be heated to reaction temperature by furnace high-temperature flue gas or radiant heat,
And in the range of about 1.5m is exported apart from concentrate burner begin to that violent combustion reaction occurs, and the input amount of mineral aggregate is more
When, in the finite spatial extent of reaction tower top feed mouth, it is difficult to ensure that mineral aggregate is enough sufficiently mixed with technique wind energy, Er Qie
Concentrate burner bottom easily generates bonding phenomenon；Simultaneously as the water cooled bottom plate of nozzle lower end, play certain heat-insulated and subtract
Few noclulation, but in actual motion, due to longtime running, certain dross phenomenon is still produced in water cooled bottom plate lower end, from
And the mass transfer of combustion reaction, rate of heat transfer are leveraged, the ferroso-ferric oxide content in clinker is not only caused to increase, dust rate
And SO3Production rate rises, and utilization ratio is also decreased obviously, and then influences the production capacity of melting product copper.
Therefore, how to ensure being sufficiently mixed for mineral aggregate and technique wind, improve the counterdiffusion of gas-solid phase, infiltration, solve in not shadow
Under conditions of ringing production, the problem of periodic cleaning nozzle lower part dross, the combustion efficiency of copper concentrate mineral aggregate is improved, this melts flash
It is extremely important for sweetening process.
Invention content
Against the above deficiency, the present invention provides one kind under conditions of production is not influenced, periodic cleaning nozzle lower junction
The problem of knurl, so as to effectively reduce the vibration premixed type concentrate spray of dross phenomenon, the combustion efficiency for improving copper concentrate mineral aggregate
Mouth.
To achieve the above object, present invention employs following technical schemes：
