Abstract
A kind of baking tail gases absorbs selenium equipment, and its structure comprises: absorbing liquid circulation barrel one, spray first, inlet exhaust gas flue, injector head two, absorbing liquid circulation barrel two, exhaust tube, vacuum ejector two, absorbing liquid recurrent canal, circulation fluid filtration machine, compression pump, vacuum ejector one.The utility model save tradition use copper-lead tower, saving construction cost, easy and simple to handle, make the precipitation output of selenium be continuous prodution, exhausting evenly, full negative-pressure operation, is beneficial to environmental protection.
Description
Technical field
The utility model relates to a kind of copper anode mud baking tail gases and absorbs selenium equipment, belongs to Copper fabrication comprehensive utilization of resources field.
Background technology
A large amount of copper anode muds can be left in Copper fabrication process, wherein containing noble metal gold, silver etc., in order to fully utilize raising Business Economic Benefit, noble metal is extracted very necessary from the earth of positive pole, roasting must be carried out by antianode mud before point copper extracts noble metal processing step, first extract selenium (se), and then point copper extracts the noble metals such as gold, silver.After turning round calcining kiln roasting by electricity, the tail gas containing selenium out obtains selenium through absorption, and be use plumbous tower to absorb selenium in the past, there is cost high, smoke absorption is incomplete, and selenium absorptivity is low, the problems such as contaminated environment.
Summary of the invention
The purpose of this utility model provides a kind of baking tail gases to absorb selenium equipment for prior art deficiency.
Absorption selenium device structure described in the utility model comprises: absorbing liquid circulation barrel one, spray first, inlet exhaust gas flue, injector head two, absorbing liquid circulation barrel two, exhaust tube, vacuum ejector two, absorbing liquid recurrent canal, circulation fluid filtration machine, compression pump, vacuum ejector one;
Above-mentioned is two cover selenium absorption equipment structures, is used alone or uses simultaneously; For wherein a set of, inlet exhaust gas flue connects vacuum ejector one, vacuum ejector one is connected with side bottom absorbing liquid circulation barrel one, be connected with circulation fluid filtration machine after opposite side Bonding pressure pump bottom absorbing liquid circulation barrel one, circulation fluid filtration machine side is connected with bottom absorbing liquid circulation barrel one by absorbing liquid recurrent canal;
Operation principle is: vacuum ejector produces negative pressure exhausting, the absorbing liquid of tail gas and extraction is fully mixed in injector head gas-liquid and contacts, be sprayed onto in absorbing liquid circulation barrel, the SeO in tail gas after gas-liquid mixed
2be dissolved in acidic aqueous solution, form selenic acid, after reaction, the selenium powder of output is suspended in absorbing liquid, then pumps into circulation fluid filtration machine with pump, is precipitated selenium, and the absorbing liquid of filter after-purification returns absorbing liquid circulation barrel, recycles.
The beneficial effects of the utility model: save tradition use copper-lead tower, saving construction cost, easy and simple to handle, make the precipitation output of selenium be continuous prodution, exhausting evenly, full negative-pressure operation, is beneficial to environmental protection.
Accompanying drawing explanation
Fig. 1 is that baking tail gases described in the utility model absorbs selenium device structure schematic diagram;
In figure: 1. absorbing liquid circulation barrel one, 2. spray first, 3. inlet exhaust gas flue, 4. injector head two, 5. absorbing liquid circulation barrel two, 6. exhaust tube, 7. vacuum ejector two, 8. absorbing liquid recurrent canal, 9. circulation fluid filtration machine, 10. compression pump, 11. vacuum ejectors one.
