Abstract
The present invention relates to a kind of waste oil miscella fuel reducing agent being applied to during metallurgical pyrometallurgical smelting, belong to metallurgical technology field.The present invention use waste oil dehydration after with methanol mixed as smelt in fuel and reducing agent, in blended fuel oil, the volume ratio of waste oil and methanol is 3:7～7:3, the carbon number that in waste oil, unit formula contains is higher than the carbon number contained in diesel oil, therefore waste oil calory burning and reduction effect are superior to diesel oil, after using fuel combination, carbon monoxide emission reduces about 50%, serve the effect of energy-saving and emission-reduction, for promoting that the energy-saving and emission-reduction of nonferrous smelting industry provide practicable Optimization-type technical scheme.
Description
Technical field
The present invention relates to a kind of waste oil miscella fuel reducing agent being applied to during metallurgical pyrometallurgical smelting, belong to metallurgical technology field.
Background technology
In recent years, the raising along with living standards of the people and the pursuit to health food, waste oil problem has caused the highest attention of society, as improper in waste oil recycling, will reflux and put on the dining table, cause threat and hidden danger to whole people's food safety.Therefore, trench oil handling is always a difficult problem for government's headache.Processing method for a long time, always allows it flow into sanitary sewage system.
Due to shortage and the pollution of environment of petroleum resources, exploring new forms of energy also becomes our problem demanding prompt solution, if can be reclaimed by waste oil and be used as the new energy, will be a kind of best processing method.The main chemical compositions of waste oil is saturated fatty acid glyceride, the carbon number that unit formula contains is higher than the carbon number contained in diesel oil, but owing in waste oil, water content is more, its calorific value diesel oil to be less than, therefore before by waste oil as fuel, have to pass through processed, and waste oil viscosity is bigger, after adding methanol, waste oil is served the abundant burning of the effect of dilution, beneficially waste oil.
Summary of the invention
The problem existed for above-mentioned prior art and deficiency, the present invention provides a kind of waste oil miscella fuel reducing agent being applied to during metallurgical pyrometallurgical smelting.This reducing agent is significantly reduced the carbon monoxide content in flue gas, it is effectively reduced the discharge of pollutant, diesel oil more than 90% can be saved, serve the effect of energy-saving and emission-reduction, for promoting that the energy-saving and emission-reduction of nonferrous smelting industry provide practicable Optimization-type technical scheme, the present invention is achieved through the following technical solutions.
A kind of waste oil miscella fuel reducing agent being applied to during metallurgical pyrometallurgical smelting, this fuel reducing agent is the blended fuel oil of waste oil and methanol, and in blended fuel oil, the volume ratio of waste oil and methanol is 3:7～7:3.
Described waste oil before combination will be through simple filtration, processed.
The invention has the beneficial effects as follows:
(1) this waste oil miscella has excellent environmental protection characteristic, and burning is more abundant, and carbon monoxide emission reduces about 50%；
(2) this waste oil miscella has excellent burning and reducing property, its calorific value of this waste oil miscella and reduction effect to be superior to diesel oil；
(3) this waste oil miscella can alternative ore diesel oil life-time service completely, use equipment and technique need not make bigger change；
(4) economical, turn waste into wealth, this waste oil miscella can be produced economic benefit as fuel or reducing agent, saved the non-renewable resources such as diesel oil simultaneously.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the invention will be further described.

Embodiment 4
The HIsmelt stove in certain ironmaking workshop, smeltery uses coal as reducing agent, in process of production coal dust is sprayed in molten bath by the way of side-blown, coal reduction FeO also produces mixed gas, substitute coal dust for 3:7 mixture blended fuel oil by volume carry out top blast using waste oil and methanol instead, on the premise of not affecting reduction effect, save substantial amounts of coal, it is achieved that the purpose of energy-saving and emission-reduction.
Embodiment 5
The HIsmelt stove in certain ironmaking workshop, smeltery uses coal as reducing agent, in process of production coal dust is sprayed in molten bath by the way of side-blown, coal reduction FeO also produces mixed gas, substitute coal dust for 7:3 mixture blended fuel oil reducing agent by volume carry out top blast using waste oil and methanol instead, on the premise of not affecting reduction effect, save substantial amounts of coal, it is achieved that the purpose of energy-saving and emission-reduction.
Above the detailed description of the invention of the present invention is explained in detail, but the present invention is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art are possessed, it is also possible to various changes can be made on the premise of without departing from present inventive concept.
