Brief description
Fig. 1 is structural representation of the present utility model;
Labelling in Fig. 1:1 is body of heater;2 is first gas mixing match instrument;3 is spray gun gas regulation conveyer device;4 is spray Rifle;5 is combustion air atmosphere adjustment device;6 is burner;7 is second gas mixing match instrument;8 is defeated for the regulation of burning zone atmosphere Send device;9 is transportation section atmosphere adjustment device.
Specific embodiment
As shown in figure 1, a kind of spray pyrolysis stove preparing pure phase Cobalto-cobaltic oxide, including the body of heater 1 of tubular structure, spray gun 4th, burner 6, meet a branch on spray gun 4, and branch sets first gas mixing match instrument 2, spray gun gas regulation conveyer device 3, First gas mixing match instrument 2 mixing compressed air and oxygen;The additional combustion air atmosphere adjustment device 5 of burner 6;Under burner 6 The high temperature combustion zone of side is provided with burning zone atmosphere and adjusts conveyer device 8, and burning zone atmosphere adjusts conveyer device 8 and connects second gas Mixing match instrument 7, second gas mixing match instrument 7 mixing compressed air and oxygen;Increase conveying in furnace bottom conveyance conduit position Section atmosphere adjustment device 9.It is in 10~60 ° of angles that described burning zone atmosphere adjusts conveyer device 8 with pyrolysis oven horizontal line.
Spray gun 4 spout is distributed in body of heater 1 inside top, has multiple spouts.Burner 6 has multiple, is distributed on burning zone, in circle Week arrangement.The particular number of spray gun 4 spout and burner 6 depending on body of heater 1 internal volume it is ensured that the inside effectively utilizes of body of heater, Guarantee the abundant pyrolysis of cobalt salt again.
Compressed air is mixed so that oxygen mole content is in mixed gas through first gas mixing match instrument 2 with oxygen 22%~80%, enter spray gun 4 after spray gun gas regulation conveyer device 3.It is laggard that mixed gas contact atomization with cobalt salt solution Enter in body of heater 1.Adjust combustion air atmosphere adjustment device 5 so that combustion air flow simultaneously:Oxygen flow is than for 5:1, highest Less than 1:2, Main Function is partial pressure of oxygen in regulating stove.Additionally, compressed air and oxygen are through second gas mixing match instrument 7 open burning zone atmosphere adjusts conveyer device 8, and adjustment oxygen mole content is 22%~80%, and gas flow rate is 5~50m/h, The burning of material can be prevented.Open transportation section atmosphere adjustment device 9, described oxygen flow is 1m/h~50 m/h, further Ensure the abundant of reaction and eliminate cobalt protoxide phase.
The utility model proposes increasing oxygen content in spray gun.Conventional spray gun is in atomization course of reaction due to reaction Diffusion time is not enough, leads to next secondary response of normoxic condition incomplete.Therefore, by first gas mixing match instrument 2 Supplemental oxygen, then enter spray gun 4 after spray gun gas regulation conveyer device 3 is adjusted so that pyrolytic reaction is more abundant.
This utility model adjusts in combustion air oxygen content so that combustion-supporting sky also by combustion air atmosphere adjustment device 5 Throughput:Oxygen flow, than increasing, increases entirety oxygen content in stove, promotes reaction further so that reaction completely, limits meanwhile The generation of oxygenerating Asia cobalt.
In actual production process, it is frequently present of the cobalt protoxide due to producing in residing time in furnace length.For this reason, this Utility model provides burning zone atmosphere and adjusts conveyer device 8, the product that purging high temperature section easy-sintering stops in time, and has been produced Raw cobalt protoxide eliminates.
This utility model also in furnace bottom conveyance conduit position increase transportation section atmosphere adjustment device 9, is carried out to furnace bottom blanking Oxygen-enriched protection again, eliminates the sub- on a small quantity cobalt phase that furnace burdening burning brings, has fundamentally prevented the generation of cobalt protoxide.
Above-mentioned spray gun gas regulation conveyer device 3, combustion air atmosphere adjustment device 5, burning zone atmosphere adjust conveying Device 8, transportation section atmosphere adjustment device 9, what basic structure was gas flow adjusting means and pressure-regulating device combines knot Structure, for the gas pressure needed for proportioning relevant device and Flow-rate adjustment, plays the mixing supplying rated condition by design condition The effect of gas.
This utility model is by the analysis of the thermodynamic model of Cobalto-cobaltic oxide thermal decomposition process and production application, real Apply the equipment design in spray gun, furnace atmosphere, high temperature section, furnace bottom section key position, efficiently solve existing Cobalto-cobaltic oxide It is also easy to produce the problem of cobalt protoxide in production process under the conditions of spray pyrolysis process.
