Способ санитарной очисткп выхлопных газов от двуокиси серы относитс к химической промышленности, цветной металлургии и другим отрасл м промышленности, имеюшим выхлопные газы, содержашие сернокислый газ.The method of sanitary cleaning of sulfur dioxide from exhaust gases relates to the chemical industry, non-ferrous metallurgy and other industries that have exhaust gases containing sulfuric acid gas.
Известные способы не обеснечивают очистку газа до санитарных норм, малоэффективны и требуют значительных капнталовложепий. Предложенный способ обеснечивает полное извлечение двуокиси серы из выхлон 1ых газов и возвраш,ение ее в процесс.The known methods do not desiccate the cleaning of gas to sanitary standards, are ineffective and require significant capital expenditures. The proposed method provides for the complete extraction of sulfur dioxide from the exhaust of the first gases and its return to the process.
Способ состоит в обработке выхлопных газов в скрубберах кислым, например сернокислым , раствором п тиокиси ванади . При этом п тивалентный ванадий восстанавливаетс до двухвалентного и окисл ет сернистый газ с образованием сульфата ванади и серной кислоты:The method consists in treating the exhaust gases in scrubbers with an acidic, for example, sulphate, solution of vanadium pentoxide. At the same time, the vanilla is boiled to bivalent and oxidizes sulfur dioxide to form vanadium sulfate and sulfuric acid:
УзОз+ЗЗОг+НоО-2VS04 + H2S04.UzOz + ZOzg + NoO-2VS04 + H2S04.
Эта реакци необратима и поэтому сернокислый газ поглошаетс до саиитарных норм.This reaction is irreversible and therefore sulfuric acid is absorbed to the sanitary norms.
Полученный раствор нанравл ют на регенерацию , котора состоит в обработке аммнаком с образованием сульфата аммони и гидрата окисп ванади :The resulting solution is applied for regeneration, which consists in treating with ammonium to form ammonium sulfate and vanadium oxide hydrate:
2VSO4 + + H, 3 (NH,),SO« + 2V (ОН), + 2Н,О,2VSO4 + + H, 3 (NH,), SO “+ 2V (OH), + 2H, O,
после фпльтрацш (ОН)2 прокаливанием перевод т в VaOs:after phltratzsh (OH) 2, calcination is transferred to VaOs:
2V(OH)2 + /20:.- V2O5-f2H.20.2V (OH) 2 + / 20:.- V2O5-f2H.20.
Растворы сульфата аммони перерабатывают в твердые соли. Оптимальное значение растворимости ЛчОз п высока растворимость SO-2 в ней достигаетс при рН 1,5 пли концентрации серной кислоты в растворе, равнойAmmonium sulphate solutions are processed into solid salts. The optimum solubility value of LCHOZ is high. The solubility of SO-2 in it is achieved at a pH of 1.5, or a concentration of sulfuric acid in the solution equal to
10-20%.10-20%.
При м е р. При температуре 25° С, линей юй скорости газовой 0,3 мсек, начальной концентрации SOo 0,5 об. %, времени контакта реагирующих масс 0,15 сек применение водной суснензии V2O5 дает степень иоглошенн SOa 53%, а применение сериокислого раствора 205 с содержанием 10% HoSO. дает степень поглощени S02 98,8%.An example. At a temperature of 25 ° С, the velocity line of the gas is 0.3 msec, the initial concentration of SOo is 0.5 vol. %, the contact time of the reacting masses is 0.15 seconds, the use of a water suspension of V2O5 gives a degree of oxidized SOa of 53%, and the use of a 205% seroacid solution containing 10% HoSO. gives an absorption ratio of S02 of 98.8%.
