Abstract
The utility model discloses a high -efficient gas reducing furnace, including the furnace body, the furnace gate setting is in the furnace body side, the furnace body front end is provided with the air inlet, and inlet set has the gas supply system in the intercommunication furnace body, and the furnace body top sets up compressed air inlet pipe and arranges the material pipe, the utility model discloses a set up the air inlet at the furnace body front end, gas supply system passes through air inlet air feed in to the stove, sets up the supply of compressed air inlet pipe compress air at the furnace body top, and the reactant expects from the row who sets up at the furnace body top that the bank of tubes removes, the utility model provides the content of impurity among the suboxide greatly falls in high oxidation quality and efficiency, makes the amount of production increase the one time, has lightened workman's intensity of labour, has reduced manufacturing cost.
Description
Technical field
The utility model belongs to metallurgical technology field, specifically a kind of high efficiency burnt gas reduction furnace.
Background technology
In existing antimony oxide production technology, to the separator of antimony oxide, what adopt is two-part reduction furnace, be that reduction furnace is divided into combustion chamber and oxidation burner hearth two parts, adopting coal is that fuel enters in oxidation furnace thorax after combustion chamber burning, impel antimony raw material to carry out oxidation reaction, finally draw antimony oxide. In long-term practice, find to adopt this reduction furnace to have larger defect, on the one hand, the redox efficiency of antimony is lower, and the impurity containing in antimony oxide is more, and redox effect is not very desirable, and output is also lower, is difficult to meet Production requirement; On the other hand, after employing coal combustion, heat antimony raw material, inefficiency, necessary outfit workman supervises reduction furnace simultaneously, adds coal, not only increases labor strength, has also improved production cost. Therefore be badly in need of the reduction furnace that a kind of production efficiency is high, can reduce production costs.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model aims to provide a kind of high efficiency burnt gas reduction furnace of effective raising treatment effeciency.
To achieve these goals, the utility model adopts such technical scheme: a kind of high efficiency burnt gas reduction furnace, comprise body of heater, fire door is arranged on body of heater side, described body of heater front end is provided with air inlet, air inlet is communicated with the oxidizing chamber in body of heater, and air inlet arranges gas handling system, and body of heater top arranges compressed air inlet pipe and drainage conduit; The utility model is by the air inlet being communicated with the oxidizing chamber in body of heater the setting of body of heater front end, air supply system by air inlet to oxidizing chamber air feed, at body of heater top, compressed air inlet pipe is set and carries out compressed-air actuated supply, oxide is got rid of from the drainage conduit that is arranged on body of heater top.
Beneficial effect: improve oxidation quality and efficiency, greatly reduce the content of impurity in oxide, make output increase by one times, alleviated workman's labour intensity, reduced production cost.
