Description
Technical field
The present invention relates to a kind of methods with damaged tire processing Pb-Zn deposits, belong to energy-saving and emission-reduction and resource comprehensive utilization technology
Field.
Background technique
Waste tire is a kind of common waste, and the whole world can produce a large amount of waste tires every year, and (2017 are 2,700,000,000
Item).Country does not allow to be poured upon in refuse landfill, therefore these wastes should be effectively addressed.So far, gasification or
Pyrolysis can be used as the main method of recycling waste tire.The pyrolysis of waste tire is usually in 400 DEG C to 800 DEG C of temperature range
It is interior, hydrocarbon and charcoal are produced after pyrolysis processing.However, when the sulfur content in these thermal decomposition products increases, it will
It can hinder their direct use.Therefore, set forth herein waste tire and Pb-Zn deposits copyrolysis is handled, by valuable metal lead
Zinc evaporates, while waste tire sulfur-bearing problem will be addressed.
Summary of the invention
For the above-mentioned problems of the prior art and deficiency, the present invention provides a kind of side with damaged tire processing Pb-Zn deposits
Method.The present invention on the basis of Method And Principle of reduction roasting, make full use of waste tire can produce reducing gas and contain and
Lead zinc high temperature is easy to the characteristics of volatilizing, and solves the problems, such as waste tire bulk deposition, has achieved the purpose that energy-saving and emission-reduction.This hair
It is bright to be achieved through the following technical solutions.
A method of Pb-Zn deposits being handled with damaged tire, the specific steps of which are as follows:
Step 1, first by Pb-Zn deposits ore grinding to granularity be 74um Pb-Zn deposits powder below, damaged tire is then broken into 0.1mm
~0.3mm damaged tire particle, it is 8~12mm pelletizing that diameter, which is made, in Pb-Zn deposits powder, damaged tire particle, binder and water；
Step 2, in the case where being passed through the gas condition that flow is 0.2~0.6L/min, the pelletizing that step 1 is obtained is warming up to 950~
40~80min is kept the temperature at 1150 DEG C and carries out reduction roasting, after high-temperature flue gas is by surface-cooler cooling in the process, through receiving
Dirt system recycles it containing the led-zinc-silver deposit in Pb-Zn dust, and flue gas removes pernicious gas by washer again, reaches emptying and requires
After be discharged into atmosphere, the magnetic separation recovery wherein iron resource after oxygen barrier cooling of the clinker after reaction.
Oxygen quality is 1.6 according to the mass ratio of C/O with carbonaceous amount in damaged tire particle in Pb-Zn deposits powder in the step 1
Pb-Zn deposits powder and damaged tire particle are uniformly mixed by~1.8:1, and water additional amount is the 3%~5% of Pb-Zn deposits silty amount.
Step 2 gas is the mixed gas with weak oxide.
Mixed gas in the step 2 with weak oxide is the air of arbitrary proportion and the mixed gas of inert gas
Or carbon dioxide and inert gas mixed gas.
The present invention puts forward to handle waste tire and Pb-Zn deposits copyrolysis, valuable metal lead zinc is evaporated, simultaneously
Waste tire sulfur-bearing problem will be addressed.In this reaction process, detailed reaction is as follows:
PbO+CO(g)=Pb+CO2(g) (1)
ZnO+CO(g)=Zn+CO2(g) (2)
ZnS+CO(g)=Zn+COS(g) (3)
Saturated vapour pressure is larger at high temperature for the lead zinc of generation, can quickly evaporate from Pb-Zn deposits.At the same time, more by force
Reduction atmosphere the oxide of iron will be reduced to reduced iron, detailed reaction is as follows:
3Fe2O3+CO(g)=2Fe3O4+CO2(g) (4)
Fe3O4+CO(g)=3FeO+CO2(g) (5)
FeO+CO(g)=Fe+CO2(g) (6)
Based on the principle of above-mentioned reduction roasting, the present invention uses waste tire and the baking mixed carry out Pb-Zn separation of Pb-Zn deposits, can
Achieve the purpose that energy-saving and emission-reduction and comprehensive utilization of resources.
The beneficial effects of the present invention are:
(1) wherein led-zinc-silver deposit and iron resource can be recycled from low-grade lead zinc ore, realize the comprehensive utilization of resource.
(2) waste tire and Pb-Zn deposits mixing reduction roasting are utilized, provides new thinking for the utilization of waste tire.
