Being provided with at furnace bottom and leading slag awl, is in order to allow distillation residue flow to slag-drip opening along leading slag awl periphery, prevent material from positive cathetus short circuit toward dirty, and the material of stove periphery is stagnated motionless phenomenon.
The utility model has enough big settling pocket in the furnace roof design, keeps the needed temperature of settling pocket, has vertically inserted electrothermal tube at the settling pocket top, to guarantee that product condenses in specified place, obtains purified product.
Described quartz electrothermal tube is that ressitance spiral is shelved in the silica tube, prevents the corrosion to resistance wire of sulfur vapor and arsenic steam, and is shelved with porcelain tube in the middle of ressitance spiral, can keep resistance wire indeformable when being subjected to thermal softening.
Described quartz electrothermal tube, it can also be the quartz electrothermal tube of both ends open, two ends with separately sealed tube good seal after, lifting one's head of adjacent both ends welded, form " U " shape or serpentine quartz electrothermal tube, so just can adopt the major diameter resistance wire, realize the 380V power supply, obtain the more large power, electrically heat pipe of optimization design, stove just can obtain bigger hot-zone volume heat load, and processing power also can be bigger.
All there is the sealed tube (11) at electrothermal tube two ends the both sides, furnace wall that quartz electrothermal tube (10) is installed, sealed tube (11) is welded on the water-cooling jacket of furnace wall, stove length direction both sides, make the intensity of furnace wall obtain guarantee, thereby stove can be increased on demand at length direction.
Area of slack water thermopair, epimere thermopair, stage casing thermopair, hypomere thermopair also are housed in stove carry out segmentation thermometric, temperature control, adopt multistage to set up thermopair separately, can reflect the actual temperature of material, convenient control.
Outstanding advantage of the present utility model is:
1, resistance wire long service life.The resistance wire of the utility model electrothermal tube neither is subjected to vacuum volatilization loss under vacuum, also be not exposed in the atmosphere, is not subjected to the oxidation of air easily.Under the situation that allows surface load, can use at least 8.93 ten thousand hours.Owing to adopt the silica tube protection, make the long service life of whole electrothermal tube.
2, the furnace wall is safe and reliable.Because furnace shell has adopted the insulating of water-cooled protection and adequate thickness, furnace wall temperature is low, even there is the arsenic steam to pass the thermal insulation layer knot on the furnace wall, also can not react with the furnace wall, so the furnace wall is safe.
3, because the long service life of electrothermal tube and body of heater, so whole device long service life.
Four, description of drawings
Fig. 1 be described in the utility model a kind of from sulfurous iron ore and arsenical pyrite coexistence mineral the apparatus structure synoptic diagram of separate sulfur arsenic iron.
Five, embodiment
Below by drawings and Examples the technical solution of the utility model is further described.
Contrast Fig. 1 described in the utility modelly a kind ofly coexists from sulfurous iron ore and arsenical pyrite that the device of separate sulfur arsenic iron is by uncovered charging basket 1 mineral, ceramic valve 2, sealing charging basket 3, ceramic valve 4, buffering charging basket 5, self-conveyor feed 6, blocking material plate 7, material diversion swash plate 9, quartz electrothermal tube 10, sealed tube 11, refractory material furnace lining 12, upper strata furnace shell 13, unequal-angle bar 14, standby electrothermal tube 15, middle level furnace shell 16, lower floor's furnace shell 17, silicon carbide divider wall 18, the area of slack water thermopair, 19, material area of slack water 20, column 21, lead slag awl 22, spiral tapping machine 23, the 2nd rectangle shaft furnace 24, lower seal inder pot 25, ceramic valve 26, lower seal inder pot 27, material lower limit reference mark 28, upper limit reference mark 29, hypomere thermopair 30, stage casing thermopair 31, epimere thermopair 32, mine dust settling pocket 33, flue 34, insulation electrothermal tube 35 constitutes.

3, control condition
Adopt the control condition of the utility model separate sulfur arsenic iron from sulfurous iron ore and arsenical pyrite coexistence mineral to be: first stove controlled temperature is at 420 ℃～450 ℃, and at this moment, sulfurous iron ore is pressed following formula and decomposed: FeS
2=FeS+1/2S
2Obtain sulphur; Second stove controlled temperature at this moment, do not had sulfurous iron ore at 750 ℃～780 ℃, has only arsenical pyrite to decompose by following formula: FeAsS=FeS+As, so just can obtain metallic arsenic.For containing arsenic 30%, sulfur-bearing 38%, the arsenic concentrate of iron content 32%, the distillation residue that calculate second stove contain S45%, contain Fe55%, can be used for fluidized bed roasting system sulfuric acid, and the roasting residue after the relieving haperacidity can be used for ironmaking.
The utility model is applicable to:
1, the distillation preliminary treatment of difficult golden arsenic concentrate can make fine and close mineral structure destroyed, reclaims gold Easier the carrying out of operation. Up to 20% golden arsenic concentrate, adopt the preliminary treatment of this type of furnace for arsenic content, take off Arsenic and slough part sulphur and reclaim again later on gold, and then send to fluidized bed roasting sulfuric acid processed, relieving haperacidity is used afterwards again In ironmaking. So this mineral have just obtained comprehensive recycling.
2, the processing of high arsenic multi-metal sulfide, at first dearsenification, again desulfurization with roasting technique relieving haperacidity is smelted then, Both utilize the sulphur in the mineral, also removed the arsenic evil in the smelting process.
3, the utility model can also be used as the high-temperature vacuum distillation stove.
