Description
One, technical field
The utility model relates to a kind of gold ore sulfation fluidizing reactor, belongs to gold smelting industry stoving oven technical field of structures.
Two, background technology
At present, domestic gold smelting industry generally adopts the cyanide process Technology to reclaim gold and silver from gold ore.In order to improve recovery of gold and silver, reduce raw material consumption such as prussiate, remove impurity components such as copper-lead zinc, the general method of sulfurization roasting that adopts is carried out oxide treatment to such gold mine, copper in the gold ore, zinc etc. are become soluble sulphate, remove by methods such as acidleach, and reclaim non-ferrous metals such as wherein copper, zinc.The major equipment of roasting oxidation method is a stoving oven, and stoving oven commonly used mainly contains rotary kiln, shaft kiln, fluidizing furnace etc.Because fluidizing furnace is simple in structure, be fit to the fluosolids roasting of sulphide ores powder raw material, and can autothermal equilibrium, serialization production etc., so the fluidized bed roasting technology develops very soon at home in recent years, corresponding fluidizing furnace form also constantly occurs.Domestic fluidizing furnace commonly used mainly is the dry feed mode at present.There are three main drawbacks in this feeding manner: the one, and raw material needs drying, and needs to pulverize and screening, has increased the raw material processing costs; The 2nd, raw material need mix and transport, the appearance mixing is inhomogeneous easily, charging is discontinuous, charging opening stops up easily etc., make the interior temperature fluctuation of stove bigger, do not allow easy operation control, owing to adopt about 600 ℃ sulfurization roasting condition, particularly when the raw material sulfur-bearing is low, be easy to dead stove, increased the difficulty of operation control; The 3rd, heat sinks such as water tank must be set in the stove, prevent that temperature is too high in the stove, guarantee the processing condition of sulfurization roasting, increased auxiliary facility.
Three, summary of the invention
The purpose of this utility model is to solve the weak point that above-mentioned prior art exists, a kind of gold ore sulfation fluidizing reactor is provided, this stoving oven changes original dry feed the mode of wet method slurry type feeding into by texture improvement, solves that gold ore fluidizing furnace job insecurity, temperature fluctuation when sulfation are big, raw material needs problems such as drying.
The utility model technical solution is as follows:
A kind of gold ore sulfation fluidizing reactor, comprise cylinder type housing 7, special character is that housing 7 inner wall surface are provided with refractory insulating layer 6 and are incubated, the bottom is an air compartment 11, be air distribution plate 2 and blast cap 1 above the air compartment, the fire-resistant pouring material of blast cap 1 usefulness is cast on the air distribution plate 2 of fire-resistant LIFT 3; At the inner blast cap of body of heater is burner hearth more than 1, comprises Boiling Combustion layer, diffusion layer, upper strata; Boiling Combustion layer top is laid with one group of spray gun jack 4, and the bottom is provided with a slag-drip opening 8 that is connected with star-like valve 9; Furnace roof central authorities top is provided with a floss hole 5, and the body of heater bottom is provided with a maintenance fire door 10;
Described housing 7 is to be made by steel plate;
The number of described spray gun jack 4 can be provided with 3-4 as required.
The utility model carries out technological transformation and finishes on original fluidized bed roasting furnace foundation, original dry feed fluidizing reactor is transformed into wet method slurry type feeding mode, dry feed mouth and feeding device on original fluidizing reactor have been deleted, deleted heat sink such as cooling water tank on original fluidizing reactor, increase by one group of (three or four) spraying gun jack, to burn the slag slag-drip opening 300～400mm that moves up, floss hole will be changed into furnace roof central authorities.
Advantage of the present utility model mainly is: simple in structure, adaptability is strong, the fluosolids roasting that is fit to the sulphide ores powder raw material, adopt wet method slurry type feeding mode, work for about 600 ℃ in the stove, can autothermal equilibrium, the serialization operation, temperature fluctuation is very little, stable working has solved the problem that original dry feed fluidizing reactor exists, and has deleted on original fluidizing reactor heat sinks such as cooling water tank simultaneously, and original raw material drying operation, reduced maintenance cost and production cost.
Four, description of drawings
Fig. 1: a kind of gold ore sulfation of the utility model embodiment fluidizing reactor structural representation.
Among the figure, blast cap 1, air distribution plate 2, fire-resistant LIFT 3, spray gun jack 4, floss hole 5, refractory insulating layer 6, housing 7, slag-drip opening 8, star-like valve 9, air compartment 11, maintenance fire door 10.
Five, embodiment
Following with reference to accompanying drawing 1, provide embodiment of the present utility model, be used for formation of the present utility model is further specified.
Embodiment
A kind of gold ore sulfation fluidizing reactor is with reference to figure 1, housing 7 is made into cylinder type by steel plate, and the outer cover of steel plate inner wall surface is provided with refractory insulating layer 6, and the bottom is an air compartment 11, be air distribution plate 2 and blast cap 1 above the air compartment, the fire-resistant pouring material of blast cap 1 usefulness is cast on the air distribution plate of fire-resistant LIFT 3; More than the inner blast cap of body of heater is burner hearth, comprises Boiling Combustion layer, diffusion layer, upper strata etc.; Boiling Combustion layer top uniform three spray gun jacks 4, the bottom is provided with a slag-drip opening 8 and is connected with star-like valve 9, furnace roof is provided with a floss hole 5, the body of heater bottom is provided with a maintenance fire door 10.
Advantage of the present utility model mainly is: simple in structure, strong adaptability is fit to the sulphide ore powder The fluosolids roasting of raw material adopts wet method slurry type feeding mode, works energy for about 600 ℃ in the stove Enough autothermal equilibriums, continuous operations, temperature fluctuation is very little, and stable working has solved original dry method The problem that the charging fluidizing reactor exists has been deleted on original fluidizing reactor cooling water tank etc. simultaneously Heat sink, and original raw material drying operation have reduced maintenance cost and production cost.
