Description

The oxygen side-blowing continuous-blowing furnace
Technical field
The utility model relates to a kind of nonferrous metallurgical equipment, specifically is a kind of oxygen side-blowing continuous-blowing furnace.
Background technology
The present pyrometallurgical smelting of China's copper, smelt stage mainly contains flash smelting, Ao Simaite melting, Rouyn-Noranda melting, Ai Sha melting, oxygen-enriched side-blowing bath melting, silver melting and traditional blast furnace smelting, electrosmelting, reverberatory smelting etc.Because shortcomings such as traditional melting mode energy consumption height, environmental pollution is serious, level of automation is low are superseded substantially.Other melting mode still is the current melting mode that adopts, and all can satisfy environmental emission standard.Blowing stage major part still adopts the PS converter, because the PS converter is to be interrupted operation, the matte of melting output adds the PS converter by the matte bag, causes the SO2 low latitude to overflow like this, and workshop condition is abominable.Because the PS converter is interrupted operation, the flue gas fluctuation is big, is unfavorable for the later stage flue gas acid preparing.
Adopt the two kinds of methods that have of continuous converting at present:
First kind is the Mitsubishi process of MIT's research and development, and its technology comprises S stove, CL stove, three stoves compositions of C stove, and three stoves connect by chute, and the S stove is the top blow smelting stove, and the CL stove is a slag cleaning furnace, and the C stove is the top blast continuous-blowing furnace.
Second kind is the copper metallurgy technology of U.S. kennecott copper smelting plant, adopts flash smelting, and the flash blowing is adopted in matte shrend, levigate, dry, and China also has copper smelting plant to adopt this technology at present.
Three stoves of first kind of Mitsubishi's technology are that height is arranged, connect by chute, like this building are just had higher requirement; Simultaneously must guarantee the equal works better of all stoves, interrupt causing producing in case a certain stove goes wrong.Second kind of flash blowing technology, matte must pass through operations such as shrend, levigate, drying, and technical process is long on the one hand, and production cost increases, and has lost high-temperature fusant physics heat on the other hand, the energy consumption increase.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of oxygen side-blowing continuous-blowing furnace is provided, and good operational environment, energy consumption is low, production is continuous, flue gas fluctuation is little.
The technical solution of the utility model is, a kind of oxygen side-blowing continuous-blowing furnace, the furnace roof that comprises cupola well, shaft and shaft top, and be provided with copper water jacket at shaft, furnace roof is provided with the molten steel cover, it is characterized in that, the outer side of copper water jacket is provided with the siphon chamber, and shaft one end is provided with the opening for feed that is communicated with copper water jacket, and the shaft the other end is provided with the siphon escape orifice that is communicated with the siphon chamber, and be respectively equipped with tuyere one time in bottom, copper water jacket 2 both sides, top, copper water jacket both sides is respectively equipped with overfiren air port; Described siphon chamber one side is provided with blowing slag escape orifice.
Furnace roof is provided with charging opening.
Furnace roof is provided with smoke outlet.
Be provided with refractory materials in the described copper water jacket.
Described molten steel cover bottom surface is provided with refractory castable.
The matte of emitting from smelting furnace passes through the opening for feed inflow continuous-blowing furnace of chute from oxygen side-blowing continuous-blowing furnace one end, flux and cold burden add from the top filling mouth, oxygen-rich air blasts the melt from a special tuyere, the violent stirring melt, speed of reaction is fast, matte blows into blister copper fast, blister copper and slag enter the siphon chamber further to be separated, blister copper is emitted from the siphon escape orifice of bottom and is entered anode refining furnace, slag is emitted shrend from cinder notch, but the air that overfiren air port enters makes the abundant after-flame of combustible gas in the copper water jacket, and the high-temperature flue gas that blowing produces enters the waste heat boiler recovery waste heat from the furnace roof exhanst gas outlet, send acid making system after electricity gathers dust.
As known from the above, the utility model adopts oxygen-enriched air converting as a kind of oxygen side-blowing continuous-blowing furnace, has improved chemical reaction rate; The matte liquid feed, energy efficient; Continuous converting, flue gas is stable to be beneficial to later stage relieving haperacidity, and has reduced labour intensity, has improved the work on the spot environment.
