Description

The continuous fuming furnace of oxygen-enriched side-blowing
Technical field
The utility model relates to the pyrometallurgy equipment in a kind of nonferrous metallurgy field, specifically is the continuous fuming furnace of a kind of oxygen-enriched side-blowing.
Background technology
At present, domestic and international plumbous field of smelting is to adopt fuming furnace reduction fuming to reclaim for the last zinc smelting slag that contains mostly.
Present employed fuming furnace weak point in general service life, big, the dangerous height of labour intensity.Fuming furnace adopts the molten steel cover to be assemblied to form, and fine coal blasts from the air port, because fine coal washes away seriously tuyere cooler, causes tuyere cooler very short service life, often needs blowing out to change water jacket.Very easily cause melt blast in the stove in case leaking appears in water jacket, abnormally dangerous to the scene.The operating type of fuming furnace is and is interrupted operation at present, and specific capacity is low, and energy consumption is high, and labour intensity is big.It is liquid that fuming furnace also requires charging, is difficult to handle cold burden.
Summary of the invention
The utility model purpose is the deficiency to prior art, provides a kind of oxygen-enriched side-blowing continuous fuming furnace, and specific capacity is high, and labour intensity is low, and operation is continuous.
The technical scheme of the utility model is that the continuous fuming furnace of a kind of oxygen-enriched side-blowing comprises cupola well, shaft and furnace roof; Be provided with at least two cooling water pipes in the cupola well; Furnace roof is provided with at least two solid-state charge doors, and shaft comprises at least three layers of water jacket arranging from top to bottom, and bottom water jacket both sides are respectively equipped with at least two tuyeres; Top layer water jacket both sides are respectively equipped with at least two secondary tuyeres, and top layer water jacket one end is provided with liquid charge door; Pour into a mould castable refractory between the cooling water pipe in the cupola well, an end is provided with the siphon chamber in the cupola well, and one end top, siphon chamber is provided with slag-drip opening, and siphon chamber one bottom portion is provided with puts plumbous mouthful.
Top, said siphon chamber is provided with burner.
When handling liquid lead reduction melting slag; Liquid lead reduction melting slag adds from the liquid charge door of continuous fuming furnace shaft one end of oxygen-enriched side-blowing continuously; Oxygen-enriched air and fine coal blast in the stove the melt from a tuyere of shaft both sides; Oxygen-enriched air strong agitation melt makes that lead, the zinc in the melt is become lead steam and zinc fume to get in the flue gas by fast restore.
Know that by above the utility model has advantages such as operating environment is good, energy consumption is low, operation is continuous, labour intensity is low as the continuous fuming furnace of a kind of oxygen-enriched side-blowing, is applicable to solid material simultaneously.
Description of drawings
The continuous fuming furnace front view of a kind of oxygen-enriched side-blowing of Fig. 1
The continuous fuming furnace side view of a kind of oxygen-enriched side-blowing of Fig. 2 is as shown in the figure:
The 1-cooling water pipe, 2-cupola well, 3-layer of copper water jacket, three layers of Copper Water Jacket of 4-
The liquid charge door of 5-, 6-molten steel cover, the solid-state charge door of 7-, 8-furnace roof water jacket; The 9-exhaust opening, 10-secondary tuyere, 11-burner, 12-siphon chamber; 13-slag-drip opening 14-is put plumbous mouthful, tuyere of 15-, 16-steelframe.
The specific embodiment
Like Fig. 1, shown in Figure 2, the continuous fuming furnace of a kind of oxygen-enriched side-blowing comprises cupola well 2, shaft and furnace roof 8; Be provided with at least two cooling water pipes 1 in the cupola well 2; Furnace roof 8 is provided with 3 solid-state charge doors 7, and shaft comprises at least three layers of water jacket arranging from top to bottom, and bottom water jacket 3 both sides are respectively equipped with at least two tuyeres 15; Top layer water jacket 4 both sides are respectively equipped with at least two secondary tuyeres 10, and top layer water jacket 4 one ends are provided with liquid charge door 5; Pour into a mould castable refractory between the cooling water pipe 1 in the cupola well, an end is provided with siphon chamber 12 in the cupola well 2, and 12 1 end tops, siphon chamber are provided with slag-drip opening 13, and siphon chamber 12 1 bottom portions are provided with puts plumbous mouthful 14.
12 tops, siphon chamber are provided with burner 11.
Bottom water jacket 3 is a Copper Water Jacket in the shaft.
Top layer water jacket 4 is Copper Water Jacket or molten steel cover in the shaft.
When the continuous fuming furnace of oxygen-enriched side-blowing is handled liquid lead reduction melting slag; Plumbous reduction melting slag is emitted from reducing and smelting furnace continuously; Add in the stoves through chute continuously from the liquid charge door of continuous fuming furnace shaft one end of oxygen-enriched side-blowing 5; Oxygen-enriched air and fine coal blast in the stove the melt from a tuyere 15 of shaft both sides continuously, and strong agitation melt, plumbous reduction melting slag reduction reaction take place in stove generate in zinc fume and the lead steam entering flue gas; Discharge entering waste heat boiler recovery waste heat from furnace roof exhaust opening 9, reclaim through bagroom at last.For making the combustible component fully burning before getting into waste heat boiler in the inner flue gas of the stove, blast air in certain amount from the secondary tuyere 10 of shaft both sides.Smelting slag gets into siphon chamber 12, discharges shrend continuously from slag-drip opening 13.
