Description

A kind of single system continuous copper smelting apparatus

Technical field

The utility model is related to non-ferrous metal metallurgy technical fields, and in particular to a kind of single system continuous copper smelting apparatus.

Background technology

Copper making technology just develops progressively towards the direction of cleaning, efficient, short route and serialization, domestic and international Copper making enterprise The Copper making technique that production capacity is big, investment is low with operating cost, operation is continuous, environmental-friendly is actively sought or developed to industry.China exists During large and medium-sized Copper making is newly-built or transformation project, the selection and exploitation of smelting technology and converting process are paid much attention to, introducing, disappearing While changing advanced technology, melting technique and continuous converting technology of the exploitation with independent intellectual property right are put forth effort on, in work Skill is developed and equipment manufacturing, operational management etc. gradually reduce and world-class gap.

Existing Copper making thermal process additionally includes flash smelting+flash based on single stove melting matte+bessemerize Blowing, the techniques such as Mitsubishi method melting+blowing, removal of impurities and desulfurization journey of the main still control copper concentrate in different stoves Degree, the shortcomings that these techniques are that the raw material-matte bessemerized is transported by metallurgical traveling crane, should in the process there are inorganization flue gas, Its air supply process is periodically, to prevent the content of sulfur dioxide in flue gas from keeping stable, influence flue gas acid preparing process simultaneously Stable operation, fire door and petticoat pipe seal are bad, largely suck air, increase equipment investment and operating cost；Flash blows It needs the matte of melting being first granulated, re-melting increases operating cost；The blister copper sulfur-bearing of Mitsubishi process blowing is high, influences Anode furnace production efficiency.

Existing converting furnace preferably completes blowing task, but existing low vacancy pollution, periodic job, high operation at Sheet, low blister copper quality, the problems such as flow is longer, and make that copper furnace structure is unreasonable, and it is still necessary to Optimal improvements.

Utility model content

For the low vacancy pollution of existing converter, relieving haperacidity cycling service fluctuation, flash blowing operating cost height, Mitsubishi's blowing Side-blown smelting technology is combined by the problems such as blister copper quality is low, the utility model with continous way converting process, provides a kind of list System continuous copper smelting apparatus, the device can repeatedly aoxidize copper concentrate in single system, are segmented deslagging, directly obtain high quality Blister copper.

To realize that purpose of utility model, the utility model use following technical scheme：

A kind of single system continuous copper smelting apparatus, including smelting zone, blowing area, siphon passage, blister copper discharge port, melting Slag discharge port and blowing slag discharge port, the smelting zone are connect with blowing area by siphon passage, and the product after one section of oxidation is logical It crosses siphon passage and is directly entered blowing area, do not need metallurgical traveling crane transhipment, solve the problems, such as the low vacancy pollution in transport process, institute State blister copper discharge port, blowing slag discharge port is connect with blowing area, the smelting slag discharge port is connect with smelting zone.

Preferably, there are liquid level differences with inside blowing area for the smelting zone, and the liquid level of the smelting zone is higher than blowing area Liquid level, the melting white metal that smelting zone generates voluntarily flow to blowing area, therefore the building base of smelting zone and blowing area because of liquid level difference Plinth may be at identical horizontal plane, it is not necessary to have normal throw, reduce production cost.

Preferably, further include top-blown spray gun and the side-blown eye of wind, the top-blown spray gun is perpendicularly inserted into from top in blowing area, For the side-blown eye of wind horizontal arrangement in blowing area both sides, impurity desulfurization is more thorough.

Preferably, the top-blown spray gun and the side-blown eye of wind are multiple, and air-supply is uniform.

The course of work：By copper-contained material（Including copper concentrate, containing copper fumes, return slag etc.）Make one section of oxidation removal in smelting zone Most iron and other impurity, obtain high-grade white metal（Cupric 70%-75%）, white metal enters blowing by siphon passage Area makees two sections of oxidations, and by top-blown spray gun and the side-blown eye of wind, into blowing area, melt is blown air feed, based on top blast, it is side-blown supplemented by, Almost all sulphur and remaining impurity are removed, the blister copper for meeting subsequent production is obtained.

The utility model has the beneficial effects that：

1, smelting zone and blowing area are combined together by the utility model by siphon passage, become an entirety, are utilized Production capacity big feature in smelting zone provides enough white metal melts, and blowing area persistently blows, and continual can produce high quality Blister copper, do not need additional transhipment and intermediary advanced treating, be allowed to continuously make copper in single device, it is steady to reach total system Surely the purpose run, improves work efficiency, and effectively reduces production cost；

2, the blowing area of the utility model during the reaction, oxidation oxygen demand, Ke Yichi is controlled by white metal amount Continuous oxygen supply, is not present periodic job process, reduces the fluctuation of acid making system, keep production run more stable；

3, the utility model fusion process all carries out in the present apparatus, and situation of leaking out existing for previous converter obtains effectively Improve, while white metal is also not required to specially treated, it is directly hot to enter blowing area, improve production efficiency；

4, all smoke evacuation points of the utility model are fixed smoke evacuation, and exhaust smoke level is limited, can all pass through live ring collection Facility collects post-processing, and handled exhaust gas volumn is only the 10%-15% of converter ring collection tolerance, and exhaust gas volumn is stablized, and is conducive to pollutant Removing is handled；

5, the utility model is due to being equipped with siphon passage, avoids the problem of outdoor chute flue gas loss, institute's loss it is micro- Amount flue gas, which can be collected all, send subsequent processing, and scene environmental protection situation is excellent；

6, the utility model solves the problems, such as that previous copper metallurgy operating cost is high, such as：Converter high warm air caused by leaking out The operating cost of machine, acid making system, to solve the ring collecting system operating cost of converter low vacancy pollution special configuration, flash blowing institute The white metal granulation of need, melting cost, Mitsubishi process blowing is caused by blister copper sulfur-bearing height needed for the reduction of anode furnace production efficiency Operating cost etc., significantly reduces operating cost.
