Abstract
The invention provides roasting tail gas selenium absorption equipment, which comprises a first absorption liquid circulation barrel, a first spraying head, a tail gas inlet flue, a second spraying head, a second absorption liquid circulation barrel, a gas suction pipe, a second vacuum sprayer, an absorption liquid return pipe, a circulation liquid filtering machine, a pressure pump and a first vacuum sprayer. The roasting tail gas selenium absorption equipment has the advantages that a conventionally used copper lead tower is omitted, the manufacturing cost is reduced, and the operation is simple and convenient, so that the selenium precipitation production is the continuous production, the air pumping is more uniform, all negative pressure operation is adopted, and the environment is favorably protected.
Description
Technical field
The present invention relates to a kind of copper anode mud baking tail gases and absorb selenium equipment, belong 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 object of the invention is to provide a kind of baking tail gases to absorb selenium equipment for prior art deficiency.
Absorption selenium device structure of the present invention 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.
Beneficial effect of the present invention: 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.
