Technical field
This utility model relates to smelting field of nonferrous metal, is specifically related to a kind of recovery system containing arsenic copper scap flue gas during smelting.
Background technology
For some areas, especially for Southwestern China area, the copper scap produced in nonferrous metallurgical process usually contains
Other non-ferrous components such as arsenic and copper, lead, antimony, gold, silver.In order to reclaim the copper scap that these non-ferrous metal metallurgies produce,
Prior art generally use copper scap pyrometallurgical smelting system these copper scap carry out pyrometallurgical smelting, copper scap pyrometallurgical smelting system
Generally comprise be sequentially connected with blast furnace, converter, reverberatory furnace, certainly, in the case of copper scap composition is single, blast furnace and
Converter can according to circumstances select to omit, and needs copper scap to obtain refined copper after passing through pyrometallurgical smelting according to smelting, in addition,
This smelting process is also accompanied by high-temperature flue gas and produces, in these high-temperature flue gas containing gaseous state arsenic and the copper of some dust-like, lead, antimony,
The non-ferrous metals such as gold, silver, if directly discharged these containing arsenic high-temperature flue gas, on the one hand, the arsenic in high-temperature flue gas and have coloured gold
Belonging to and can not get effectively recycling, reduce the response rate of copper scap, on the other hand, the arsenic in high-temperature flue gas directly discharges meeting
Cause environmental pollution, the environmental pollution brought in order to avoid the high-temperature flue gas containing arsenic in prior art, need when copper scap pyrometallurgical smelting
Consume substantial amounts of soda arsenic removal, and during arsenic removal, also can take away the antimony of a part, cause the unnecessary wasting of resources.
Utility model content
Technical problem to be solved in the utility model is the recovery containing arsenic copper scap flue gas during smelting providing a kind of response rate higher
System.
In order to solve above-mentioned problem of the prior art, this utility model realizes by the following technical solutions:
This utility model recovery system containing arsenic copper scap flue gas during smelting, including the high temperature being connected with the copper scap smelting system port of export
Filter, high-temperature filter use sintering inorganic porous material as filtering material, the gas temperature of the high-temperature filter port of export >=
320 DEG C, the high-temperature filter port of export is connected with heat-exchanger rig, heat-exchanger rig port of export gas temperature≤150 DEG C, and heat-exchanger rig exports
End is connected with cleaner unit, also includes driving high-temperature flue gas successively along high-temperature filter, heat-exchanger rig, the blower fan of cleaner unit flowing.From
In the high-temperature flue gas that copper scap smelting system is discharged, containing the arsenic of gaseous state and the copper of dust-like, lead, antimony, gold, silver etc., other has
Non-ferrous metal composition, when high-temperature flue gas is by high-temperature filter, is resistant to 400 DEG C owing to the filtering material of high-temperature filter uses
The sintering inorganic porous material that high temperature above, filtering accuracy are higher, therefore the copper of dust-like in high-temperature flue gas, lead, antimony, gold,
Silver wait other non-ferrous component can be filtered, now high-temperature flue-gas ensure that arsenic still in gaseous state, therefore high temperature
Filter only intercepts the non-ferrous metal of dust-like, and arsenic can pass through high-temperature filter, after through heat-exchanger rig cool down after at a temperature of
Being down to≤150 DEG C, thus arsenic is transferred to solid-state by gaseous state, is unified in cleaner unit afterwards and is collected, thus by non-ferrous metal with arsenic very
Separating well, improve both response rate, in addition, and high-temperature flue gas expellant gas after double-filtration is clean
Cleanliness is higher, does not results in environmental pollution.
As the further restriction of the above-mentioned recovery system containing arsenic copper scap flue gas during smelting, described heat-exchanger rig is surface cooler.Described
The surface cooler coefficient of overall heat transmission is high, and water resistance is little, substantially increases heat exchange efficiency.
Further, described sintering inorganic porous material is flexible, porous metal forming, and flexible, porous metal forming is flexible, can basis
Filtration needs folding to be processed into different shape, and keeps preferable filtration flux, and in addition flexible, porous metal forming is high temperature resistant,
Use intensity is high.The aperture of the most described flexible, porous metal forming is 0.05 μm-100 μm, and that can filter as required is coloured
The particle diameter of metallic dust particles, selects corresponding flexible, porous metal forming aperture, thus meets filtering accuracy requirement.Preferably described
The thickness of flexible, porous metal forming is 5-1500 μm, and under this thickness, flexible, porous metal forming is flexible, and filtration flux is big.Excellent
The porosity selecting described flexible, porous metal forming is 15-70%, and under this porosity ranges, flexible, porous metal forming performance of ventilating is good,
Resistance is less.
Further, described cleaner unit is fiber bag precipitator.After heat-exchanger rig heat exchange, high-temperature flue-gas is down to≤
150 DEG C, so herein without using other resistant to elevated temperatures defecator, using fiber bag precipitator can meet requirement, thus saving
Cost recovery containing about arsenic copper scap flue gas during smelting.
Below by way of the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Detailed description of the invention
It is applied in copper scap smelting system below by way of by a kind of for this utility model recovery system containing arsenic copper scap flue gas during smelting,
Thus the utility model is described in further detail, blast furnace that described copper scap smelting system includes being sequentially connected, converter, reflection
