Abstract
The invention discloses a process method for continuously smelting a plurality of metalliferous materials by utilizing a rotary kiln and a smelter hearth, which is characterized in that the method comprises the following steps: a. materials are proportioned; ironstone or other valuable metalliferous materials and auxiliary materials are proportioned together; b. the materials are heated to volatilize, so that valuable metals such as zinc, lead, etc. in the materials are volatilized in a form of gas, then the gas is cooled to form powder products by a product collected system to recover valuable metals such as zinc oxide, lead oxide, etc, and the exhaust gas can meet the standard requirements; c. metals which are not volatilized in the gas form roll to the discharge hole of the rotary kiln and directly enter into the smelter hearth for iron extraction, and small amount of coke and the auxiliary materials are added during the smelting process so that the temperature of the materials in the smelter hearth can be increased continuously. The invention can process large amount of ironstone or other a plurality of valuable metalliferous materials, needs less investment, has simple structure, good economic benefits as well as environmental benefits, and conforms to the national policies of energy-saving, emission-reduction and comprehensive utilization of resources.
Description
Technical field
The present invention relates to the Metal smelting technical field, more particularly relate to the processing method of the multiple metalliferous material of a kind of continuous smelting.
Background technology
Traditional technology is utilized the blast-furnace smelting iron ore, it requires iron ore to contain Fe can not to be lower than 50%, to contain Zn and can not be higher than 0.2%, contain AS, contain S, contain P etc. and all can not exceed in the indication range, unfavorable factors such as so its smelting requirements height, combustion intensity are greatly, investment is big, equipment is huge, energy consumption is big, labour intensity is big.Also have, its technical process can not be handled the material of multiple metals such as containing zinc, iron, copper, and social now upward existence contains multiple metalliferous material in a large number, and there is certain harm in environment, therefore studies new art breading the problems referred to above and is necessary.
Summary of the invention
Purpose of the present invention is exactly simple, the safety of a kind of not only technology that provides for the deficiency that solves prior art, manageable, energy consumption is low, and economic benefit is good, and utilize rotary kiln and smelting furnace that environmental benefit is good are smelted the processing method of multiple metalliferous material continuously.
The present invention adopts following technical solution to realize above-mentioned purpose: a kind of processing method of utilizing rotary kiln and smelting furnace to smelt multiple metalliferous material continuously is characterized in that it comprises the steps:
A, batching are with iron ore or contain other valuable metal materials such as zinc, iron and supplies are together prepared burden;
B, utilize the characteristics of rotary kiln to heat continuously, material is heated to volatilizable, make valuable metals such as zinc in its material, lead evaporate with gas form, utilize the product gathering system to make its gas cooling cooling form powder shape product again and reclaim valuable metals such as zinc oxide, plumbous oxide, tail gas qualified discharge;
The discharge port that c, the metal that does not evaporate with gas form are rolled to rotary kiln directly enters smelting furnace and refines the pig iron under the situation that not have cooling, add a small amount of coke and auxiliary material in the smelting process, makes the interior sustainable intensification of material of stove.
As further specifying of such scheme, in the smelting process of above-mentioned processing step c, also can produce a small amount of gas, gas inserts rotary kiln once more and carries out secondary recovery.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
The present invention adopt self research and development the refinement of rotary kiln and smelting furnace technology continuity iron ore or iron content, contain multiple valuable metal materials such as zinc, leaded, cupric, multiple valuable metal materials amounts such as technical process handles iron ore or iron content, contains zinc, leaded, cupric are big, required less investment (blast furnace with respect to same output comes comparison), needed human and material resources, shared place are few, technology is simple, safety, manageable, energy consumption is low, economic benefit is good, environmental benefit is good, meets national energy-saving and emission-reduction, comprehensive utilization of resources policy.
Description of drawings
Fig. 1 is a process flow sheet of the present invention.
Embodiment
As shown in Figure 1, a kind of processing method of utilizing rotary kiln and smelting furnace to smelt multiple metalliferous material continuously of the present invention, utilize self research and development the refinement of rotary kiln and smelting furnace technology continuity iron ore or iron content, contain multiple valuable metal materials such as zinc, leaded, cupric, process is successive.Specifically comprise the steps:
A, batching are with iron ore or contain other valuable metal materials such as zinc, iron and supplies are together prepared burden;
B, utilize the characteristics of rotary kiln to heat continuously, material is heated to volatilizable, make valuable metals such as zinc in its material, lead evaporate with gas form, utilize the product gathering system to make its gas cooling cooling form powder shape product again and reclaim valuable metals such as zinc oxide, plumbous oxide, tail gas qualified discharge; Also can produce a small amount of gas in such smelting process, gas can insert rotary kiln once more to carry out metals such as secondary recovery inflammable gas, zinc, lead and makes the rate of recovery can reach more than 99%;
The discharge port that c, the metal that does not evaporate with gas form are rolled to rotary kiln directly enters smelting furnace and refines the pig iron under the situation that not have cooling, add a small amount of coke and auxiliary material in the smelting process, makes the interior sustainable intensification of material of stove.
Multiple valuable metal materials amounts such as this technical process handles iron ore or iron content, contains zinc, leaded, cupric are big, blast furnace with respect to same output comes comparison, required less investment, needed human and material resources, shared place are few, and technology is simple, safety, and is manageable, energy consumption is low, economic benefit is good, and environmental benefit is good, meets national energy-saving and emission-reduction, comprehensive utilization of resources policy.
As previously discussed, only be preferred embodiment of the present invention, can not limit the present invention's interest field with this, therefore the equivalent variations of being done according to the present patent application claim still belongs to the scope that the present invention is contained.
