The specific embodiment
Embodiment 1
Shown in the structural representation of this titanium slag stove after burner of Fig. 1 and Fig. 2, combustion chamber cavity 4 is fixedly to be formed by two-layer up and down, and two-layer combustion chamber cavity 4 all is pyramidal structures up and down, and the larger diameter end docking of two conical combustor cavitys 4 is fixed; The sidewall of combustion chamber cavity 4 is divided into inside and outside two-layer; be provided with cyclic water channel 7 between the inside and outside two-layer sidewall; cyclic water channel 7 is come round with the delivery port 5 at cavity 4 tops, combustion chamber, upper strata and the water inlet 1 of lower floor combustion chamber cavity 4 bottoms respectively; consist of water-cooling circulating system, the entity service life of protection secondary combustion chamber.
The madial wall of combustion chamber cavity 4 is carbon steel plate materials, and purpose is to strengthen the non-oxidizability of inwall, guarantees the Long-Term Properties of inwall.
Also be distributed with gaseous mixture burner 2 on the sidewall of lower floor's combustion chamber cavity 4, gaseous mixture burner 2 passes interior lateral wall and extends in the combustion chamber cavity 4, gaseous mixture burner 2 is by consisting of for valve, gas jet, spark plug, be connected with air-blaster for valve, passed through for valve to combustion chamber cavity 4 interior air supplies by air-blaster; Gas jet is connected with gas-pipe line, and the gas jet place also is equipped with gas valve, by the supply of gas valve control coal gas; Spark plug is positioned at the exit for valve and gas jet, is used for lighting the mist of air and composition of coal gas, and spark plug also is electrically connected with electronic ignitor switch, by electronic ignitor switch spark plug is powered and strikes sparks.
During work, air-blaster is started to gaseous mixture burner 2 air feed, regulate supply gas pressure 0.5kg/cm state, valve turns on the gas-fire, regulate gas pressure 0.2kg/cm, simultaneously with the spark plug power supply sparking of electronic ignitor switch to gaseous mixture burner 2, the mist of the burner that ignites ejection, also can Judas-hole 6 be set at taper secondary combustion chamber middle part, by the fired state in the Judas-hole 6 observation combustion chamber cavitys 4; After the burner normal operation, gaseous mixture burner 2 jets out flames, and the CO gas that the titanium slag fire grate that constantly burns is put makes the titanium slag kiln gas realize second-time burning.
This device is owing to being located at electric furnace flue position, the special construction of cone-shaped cavity can satisfy airtight burning and the rapid expanding of gas, the traction electric furnace flue gas carries out the abundant burning of CO gas continuously, expand, ejection, gas after the burning enters the electric furnace water-cooling flue, gas after burning composition at this moment is high temperature carbon dioxide gas, by water-cooled flue the continuous cooling of burnt gas is imported pipeline of dust collector continuously, the gas that this moment, deduster was accepted is carbon dioxide, and a small amount of exhaust gas dust, reached the safe Acceptable criterion of smoke duster, reached the purpose of titanium slag kiln gas second-time burning, fundamentally stopped to produce flue gas and dodged quick-fried possibility.Reached the safe handling purpose of titanium slag stove.
When this device is normally produced at the titanium slag stove, the CO gas that smelting furnace material produces in can the completing combustion electric furnace, the pitch steam coal tar completing combustion that high-titanium slag smelting can be produced simultaneously, the coal tar of stopping in the flue gas is bonded on the cloth bag owing to lowering the temperature to solidify at the dust-collecting bag place, cause the bonding obstruction of filter bag tar, deduster can not be worked, use this device meeting completing combustion coal tar gas, purifying smoke improves the deduster condition of work fully, because this equipment adopts complete water collar assembling structure, this equipment without impact, possesses perfect cleaner production requirement on external environment condition.
