Technical field
The present invention relates to prepare red lead technical field, relate in particular to one and utilize intelligent apparatus of oxygen supply to prepare fast the method for red lead (tri-lead tetroxide).
Background technology
Prepare the chemical equation of red lead product (tri-lead tetroxide):
①、
②、
Can obtain according to mass conservation law, the electrolytic lead roasting oxidation of 1 ton can generate the pbo of 1.07729 tons, and then can generate 1.10305 tons of pb3o4, i.e. red lead product through calcined oxide.0.10305 ton of rising foam is the needed oxygen quality of lead material complete oxidation.As everyone knows, under normal temperature and pressure, it is 21% that oxygen accounts for air ratio, oxygen density 1.429g/L, every m
3air in only contain 0.0003 ton of oxygen under normal temperature and pressure, and under hot conditions, oxygen is thinner, can not meet the oxidation needs of lead material far away, and can only rely on prolongation oxidization time, just can produce red lead product.
The method of industrial production red lead is mainly by after electrolytic lead heating and melting both at home and abroad at present, and ball mill pulverizing generates pbo through the temperature nature roasting oxidation of 300 DEG C, then, through the high-temperature calcination natural oxidation of 500 DEG C, obtains pb
3o
4it is red lead product, even if state-of-the-art " dry wet method novel process " produces red lead now, also to pass through roasting and calcination stage, the shortcoming of traditional method: due to roasting storehouse, oxidation storehouse at high temperature, oxygen deficiency, can not meet the oxidation demand of plumbous material, can only rely on prolongation oxidization time, just can obtain red lead product, energy consumption is excessive, production cost is high, and production efficiency is low.
Summary of the invention
Technical problem to be solved by this invention is to provide the method for utilizing intelligent apparatus of oxygen supply to prepare fast red lead, and the method can shorten oxidization time, improves production capacity, save energy, and reduction expends, and saves production cost, and enhances productivity.
For achieving the above object, the invention provides following technical scheme: a kind of using method of utilizing intelligent apparatus of oxygen supply to prepare fast red lead, by intelligent apparatus of oxygen supply, for the preparation of red lead (tri-lead tetroxide), the method comprises the following steps:
1) purity oxygen oxygen generating plant in intelligent apparatus of oxygen supply being made compresses and stores;
2) will make purity oxygen and add Dilution air, and will under oxygen level normal temperature and pressure, be controlled at 35-40% by intelligent oxygen determination equipment, during below or above this numerical value, intelligent oxygen determination device intelligence is opened or is closed and adds air switch;
3) oxygen diluting is stored into gas-holder;
4) by solar heat collector or electric heater unit, gas-holder is heated, temperature is controlled at 200 DEG C;
5) be that the oxygen of 200 DEG C injects roasting storehouse, oxidation storehouse by fan, airway with the speed of 10L/m by temperature.
Adopt the beneficial effect of above technical scheme to be: a kind of using method of utilizing intelligent apparatus of oxygen supply to prepare fast red lead, the method can shorten oxidization time, improves production capacity, save energy, reduction expends, and saves production cost, and enhances productivity.
Embodiment
Describe the preferred embodiment of the present invention below in detail.
Embodiment 1: a kind of using method of utilizing intelligent apparatus of oxygen supply to prepare fast red lead, by intelligent apparatus of oxygen supply, for the preparation of red lead (tri-lead tetroxide), the method comprises the following steps:
1) purity oxygen oxygen generating plant in intelligent apparatus of oxygen supply being made compresses and stores;
2) will make purity oxygen and add Dilution air, will under oxygen level normal temperature and pressure, be controlled at 38% by intelligent oxygen determination equipment, during higher than this numerical value, intelligent oxygen determination device intelligence
3) close and add air switch;
4) oxygen diluting is stored into gas-holder;
5) by solar heat collector or electric heater unit, gas-holder is heated, temperature is controlled at 200 DEG C;
5) be that the oxygen of 200 DEG C injects roasting storehouse, oxidation storehouse by fan, airway with the speed of 10L/m by temperature.
Adopt the beneficial effect of above technical scheme to be: a kind of method of utilizing intelligent apparatus of oxygen supply to prepare fast red lead, the method shortens oxidization time, improve production capacity, because point of the present invention is to allow lead material touch sufficient oxygen, under hot conditions, realize accelerated oxidation, the oxidation time that has greatly shortened red lead product, has improved throughput.According to test, previous oxidized still is implemented in invention, and (general volume is 1.96m
3) running at full capacity, within one day, can only produce 6.02 tons of red lead products, after invention is implemented, under lead material equal conditions, can shorten half, day output reaches 11.81 tons, save energy, reduction expends, before invention is implemented, one ton of red lead product of every production, about electricity consumption 398 is spent, invent after implementing due to oxidated time shorten and the impact of the double factor of raising output, a red lead product power consumption 137 per ton is spent, save energy reduction expends successful, save production cost, enhance productivity, generally, the fixed cost of enterprise does not increase with output, because production capacity after implementing the present invention promotes nearly one times, red lead cost per ton also declines by a relatively large margin.As cost of labor drops to 129.9 yuan by original 283.3 yuan per ton, therefore production cost has been saved in enforcement of the present invention, has improved production efficiency.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
