Abstract
The utility model discloses a zinc recycling device using a rotary kiln. The zinc recycling device comprises a rotary kiln and is characterized in that a gas outlet of the rotary kiln is communicated with an inlet of a settling chamber, a gas outlet of the settling chamber is communicated with an inlet of a surface air cooler, and a gas outlet of the surface air cooler is communicated with an inlet of a dust chamber through a centrifugal fan. By using the zinc recycling device using the rotary kiln, disclosed by the utility model, zinc in blast-furnace ash, gas mud and electric-furnace ash can be effectively recycled, the problem that the blast-furnace ash, the gas mud and the electric-furnace ash are difficult to treat is solved, and the high social benefit and environment benefit are achieved while the economic benefit is achieved.
Description
Technical field
The utility model relates to the technical field of utilizing rotary kiln to reclaim zinc, refers more particularly to the receipts zinc device that utilizes rotary kiln.
Background technology
In the blast furnace ironmaking process, contained impurity in iron ore is reduced as lead, zinc etc., and at high temperature forms steam, outside being come out of the stove by band with blast furnace gas together with the fine dust of ore, coke, flux etc., then by the outer coal gas dust removal purification system of stove, it is being caught and removing.Gas dust removal system is comprised of two sections of gravitational dust collection and meticulous dedustings, captures through first paragraph the dry type coarse dust that gets off and is called gravitational dust; The meticulous fly-ash separator of second segment generally adopts dry bag-type dust remover or wet dedusting system, and the dry type grain dust that dry gas cleaning obtains is called gas ash (claiming again blast-furnace dust, light ash); The product that wet dust removal obtains mud of gained after precipitation process is called gas mud.
The electric furnace ash is a kind of in ion dust mud contaning, and when being Electric furnace steel making, electric furnace dust is processed through trap, flue, finally by sack cleaner and captured, and steel generation per ton is 5～20Kg.Often process galvanized sheet and other and contain zinc, plumbous Corrosion-proof steel products due to electric furnace, make the electric furnace ash contain zinc, plumbous amount is higher.
In above-mentioned blast-furnace dust, gas mud, electric furnace ash, zinc content is higher, causes waste because not obtaining effective recycling at present, and environment has also been polluted in this waste simultaneously.
The utility model content
The purpose of this utility model is to provide a kind of receipts zinc device that utilizes rotary kiln that the zinc in blast-furnace dust, gas mud, electric furnace ash can be reclaimed.
For achieving the above object, the utility model has adopted following technical scheme.
The described receipts zinc device that utilizes rotary kiln, comprise rotary kiln, be characterized in: the air outlet of rotary kiln is connected with the entrance of settling pocket, and the air outlet of settling pocket is connected with the entrance of surface cooler, and the air outlet of surface cooler is connected with the entrance of dust chamber by centrifugal blower.
The beneficial effects of the utility model: utilize the receipts zinc device that utilizes rotary kiln described in the utility model, can make the zinc in blast-furnace dust, gas mud, electric furnace ash obtain effective recycling, solved simultaneously the processing problem of blast-furnace dust, gas mud, electric furnace ash; When obtaining economic benefit, social benefit and environmental benefit have preferably been gathered in the crops again.
Description of drawings
Fig. 1 is the structural representation that utilizes the receipts zinc device of rotary kiln described in the utility model.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the receipts zinc device of rotary kiln that utilizes described in the utility model is further described.
Shown in Figure 1, the described concrete structure of the receipts zinc device of rotary kiln that utilizes is: comprise rotary kiln 1, the air outlet of rotary kiln 1 is connected with the entrance of settling pocket 2, the air outlet of settling pocket 2 is connected with the entrance of surface cooler 3, and the air outlet of surface cooler 3 is connected by the entrance of centrifugal blower 4 with dust chamber 5.
In actual use, utilize above-mentioned receipts zinc device, can carry out by following processing step the recovery of zinc, concrete steps are as follows: ⑴ allocates electric furnace ash, hard coal and gas mud in blast-furnace dust, and blast-furnace dust: the electric furnace ash: hard coal: the ratio of the parts by weight of gas mud is 6: (1.5～2.5): (0.8～1.2): (0.8～1.2) obtains mix; ⑵ be delivered to high-temp combustion in rotary kiln 1 with the mix of step ⑴ by the entrance of rotary kiln 1, and temperature is controlled at 800 ℃～1050 ℃, makes the zinc gasification in blast-furnace dust, electric furnace ash, gas mud, forms gasification zinc; ⑶ under the effect of centrifugal blower 4, and the gasification zinc that step ⑵ forms is inhaled into settling pocket 2, makes the smoke dust that is blended in gasification zinc freely fall and be separated, and temperature drops to 350 ℃～450 ℃ in this process; ⑷ the zinc that then gasifies continues to move ahead and enters surface cooler 3, after entering surface cooler 3, makes temperature fast-descending to 110 ℃～130 ℃ in 25 seconds～35 seconds, gasification zinc and airborne combination with oxygen generation zinc oxide in this process; ⑸ send zinc oxide into dust chamber 5 by centrifugal blower 4, falls into the bucket that gathers dust of dust chamber in dust chamber after Bag filter, stores at last and reclaim.In actual use, but the choice for use thermal value also can select other processing step that is fit to carry out the recovery of zinc at the hard coal of 5500 kilocalorie/kilograms～8000 kilocalorie/kilograms.
From the above mentioned as can be known, utilize the receipts zinc device that utilizes rotary kiln described in the utility model, can make the zinc in blast-furnace dust, gas mud, electric furnace ash obtain effective recycling, solved simultaneously the processing problem of blast-furnace dust, gas mud, electric furnace ash; When obtaining economic benefit, social benefit and environmental benefit have preferably been gathered in the crops again.
