| titleOfInvention | The method of sulfuric acid industry Two-way Cycle jet-type arsenic removal |
| abstract | The invention provides the method and apparatus of a kind of vitriol works Two-way Cycle jet-type arsenic removal.Vulcanizing agent is placed in hydrogen sulfide generator, and the hydrogen sulfide of generation enters reactor (3) by pipeline, and ON cycle pump (5) makes the material in reactor (3) carry out internal recycle; Simultaneous reactions still (3) remaining hydrogen sulfide enters reactor (4), and ON cycle pump (6) makes the material in reactor (4) carry out internal recycle.After question response 60 ~ 90min, by pipeline, reactor (3) reacted liquid is placed in storage tank, after leaving standstill 30 ~ 60min, liquid is carried out press filtration, the filter residue obtained can deliver to the recovery that smeltery carries out heavy metal, filtrate is directly discharged, and the waste liquid of reactor (4) then gives over to the reaction solution into next round reactor (3).The clearance of arsenic of the present invention reaches more than 99%, and filter residue arsenic content is high, is conducive to deep processing. |
