Description
Technical field
The utility model belongs to solid waste resource reutilization technology field, and in particular to Zinc-Bearing Wastes extract time oxidation
Zinc device, the extraction for metallic element zinc in metallurgy industry dedusting ash containing zinc.
Background technique
In steel smelting procedure, harmful substance zinc can be progressively enriched with smelting procedure, be finally enriched in dedusting ash,
That is Zinc-Bearing Wastes.
Steel and iron industry every annual meeting in China's generates the Zinc-Bearing Wastes of up to ten million tons.Domestic iron and steel enterprises are to Zinc-Bearing Wastes at present
Treating method is mainly physical method and wet process, but these methods all be there is a problem that corresponding, be unable to satisfy modern state environmental protection
Policy and regulation can not meet the strategy and policy of circular economy and sustainable development.Therefore, new technology is researched and developed
Route come rationally dispose Zinc-Bearing Wastes become there is an urgent need to.
Summary of the invention
For the prior art with enterprising demand, the utility model provides Zinc-Bearing Wastes and extracts secondary zinc oxide device,
Purpose is the resource utilization of realization Zinc-Bearing Wastes to the greatest extent, solves the problems, such as that iron and steel enterprise's Zinc-Bearing Wastes are intractable,
Sync enrichment extracts production secondary zinc oxide and high-speed rail kiln slag product, realizes that Zinc-Bearing Wastes are innoxious, resource utilization, improves steel
Iron corporate social, economy and environmental benefit meet the sustainable development direction of national industry.
To achieve the above object, it according to the one aspect of the utility model, provides zinc fume mud and extracts secondary zinc oxide device,
Including mixing blender, pelletizer, rotary kiln, surface air cooler, deduster, desulfurizing tower；Mixing blender, pelletizer, rotary kiln, table
Cooler, deduster, desulfurizing tower pass sequentially through pipeline connection；
The mixing blender mixes stirring for Zinc-Bearing Wastes and reducing agent.
According to the utility model embodiment, reduction volatilization reaction zone temperature is 900~1200 DEG C in the rotary kiln.
The main flow that zinc fume mud extracts secondary zinc oxide device is as follows: Zinc-Bearing Wastes and reducing agent being mixed and are stirred through mixing
Device stirring, is granulated into pelletizer, enters rotary kiln by kiln tail, material containing zinc is in kiln body successively by dry, preheating, reduction
Volatilization, cooling；Reduction volatilization reaction zone temperature is 900~1200 DEG C in rotary kiln, after discharge flue gas is cooled down by surface air cooler, through removing
Qualified discharge after dirt device, desulfurizing tower flue gas purification system purified treatment.
Kiln slag returns to steel mill's smelting system as rich iron charge and recycles after slag handling system is cooling.
In general, the above technical solutions conceived by the present invention are compared with the prior art, due to the provision of
Zinc fume mud extract secondary zinc oxide device, can achieve the following beneficial effects: (1) using rotary kiln pyrogenic process mention zinc be able to satisfy country and
The environmental requirement in place；(2) secondary zinc oxide is extracted using Zinc-Bearing Wastes, while produces rich iron charge, can effectively solve Zinc-Bearing Wastes
The harmful elements such as middle zinc are normally produced to subsequent blast furnace and the adverse effect of blast furnace service life, and facilitate iron and steel enterprise's realization
Saving energy, lowering energy consumption and reducing pollutants discharge, economical, society, obvious environment benefit；(3) device has compact-sized, flexible arrangement, and recovery rate is high, fortune
The stable feature of row.
Detailed description of the invention
Fig. 1 is that zinc fume mud extracts secondary zinc oxide structure drawing of device.
In figure: 1- mixing blender；2- pelletizer；3- rotary kiln；4- surface air cooler；5- deduster；6- desulfurizing tower.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.In addition, institute in the various embodiments of the present invention described below
The technical characteristic being related to can be combined with each other as long as they do not conflict with each other.
As shown in Figure 1, zinc fume mud extraction secondary zinc oxide device, including mixing blender 1, pelletizer 2, rotary kiln 3, table are cold
Device 4, deduster 5, desulfurizing tower 6；Mixing blender 1, pelletizer 2, rotary kiln 3, surface air cooler 4, deduster 5, desulfurizing tower 6 successively lead to
Piping connection.
Zinc-Bearing Wastes and reducing agent are mixed and are stirred through mixing blender 1, is granulated into pelletizer 2, is entered back by kiln tail
Rotary kiln 3, material containing zinc successively pass through drying, preheating, reduction volatilization, cooling in kiln body；Reduction volatilization reaction zone in rotary kiln 3
Temperature is 900~1200 DEG C, after discharge flue gas is cooled down by surface air cooler 4, at deduster 5,6 flue gas purification system purification of desulfurizing tower
Qualified discharge after reason.
Embodiment: using certain steel mill's furnace cloth bag dust-removing ash as raw material, the material after granulation enters rotary kiln 3, has in material
Valence element zinc is reduced into gas phase, is oxidized to oxide, i.e. zinc oxide fumes in the gas phase, is then collected into deduster
In 5, become Second-rate zinc oxide powder, kiln slag transports the processing of back segment process after entering the flame-out cooling of cooling kiln.
Verified, using present apparatus dezinc degree > 90%, Zn content is greater than 45% in product.
As it will be easily appreciated by one skilled in the art that the above is only the preferred embodiment of the utility model only, not
