Description
Technical field
The present invention relates to Plumbum preparatium processing technique field, be specifically related to one and utilize air stream quickly to prepare Plumbum preparatium
Method.
Background technology
After electrolytic lead is mainly added heat fusing by the method for commercial production Plumbum preparatium the most both at home and abroad, ball mill pulverizing,
Generate pbo through the temperature nature roasting oxidations of 300 DEG C, be then passed through the high-temperature calcination nature oxygen of 500 DEG C
Change, obtain pb3O4I.e. Plumbum preparatium product, even if the most state-of-the-art " wet-dry change new technology " produces Plumbum preparatium,
Also will be through roasting and calcination stage.The shortcoming of traditional method: due to roasting storehouse, oxidation storehouse at high temperature
Under, oxygen is not enough, it is impossible to meets the oxidation demand of lead material, can only rely on prolongation oxidization time, could obtain
To Plumbum preparatium product, energy resource consumption is excessive, and production cost is high, and production efficiency is low.
In order to accelerate oxidation reaction speed in traditional Plumbum preparatium production process, take to add in oxidation furnace one
The solid ammonium nitrate of certainty ratio, it is well known that " solid ammonium nitrate " is at high temperature, high pressure and has oxidable
Material in the presence of, it may occur that blast, therefore to there is considerable safety raw for tradition Plumbum preparatium production technology
Produce hidden danger；It is again the raw material preparing explosive simultaneously, if mismanagement or stolen flow direction society, will
Entail dangers to social public security or cause other to endanger for other illegal objectives.As Chinese patent " utilizes
The intelligence apparatus of oxygen supply method of quickly preparing Plumbum preparatium " (CN201410216814.9) disclose by by intelligence
Can the oxygen for preparing of apparatus of oxygen supply, by diluting, compress, preheating, the technique such as conveying, to meet lead button
