Description
Предложен способ регенерации растворов сульфит-бисульфита аммони при а1ммиачном способе очистки промышленных газов от сернистого ангидрида.A method is proposed for the regeneration of ammonium sulfite bisulfite solutions in the aluminum process of purification of industrial gases from sulfur dioxide.
По предлагаемому способу раствор сульфит-бисульфита аммони , вытекающий из абсорбера, где осуществл етс поглощени сернистого ангидрида из газов, обрабатываетс при кип чении раствором сернокислого алюмини . При этом выдел етс 100%-ный сернистый ангидрид и получаетс щлам, содержащий основную соль АЬОз 50з 2Н20, а в растворе остаетс сульфит аммони . Сульфит аммони , накапливающийс в растворе, направл етс в специальный аппарат на спекание при температуре 350° с золой, с целью получени АЬОз (8О4)з, необходимого дл осуществлени процесса выделени сернистого ангидрида из поглотительного раствора сульфит-бисульфита аммони . При этом регенерируетс аммиак, который возвращаетс в цикл дл поглощени сернистого газа.According to the proposed method, a solution of ammonium sulfite bisulfite, flowing from the absorber, where absorption of sulfur dioxide from gases is carried out, is treated at the boil with a solution of aluminum sulfate. In this case, 100% sulfuric anhydride is released and gaps containing the basic salt ABO3 503 2H20 are obtained, and ammonium sulfite remains in the solution. The ammonium sulphite accumulating in the solution is sent to a special apparatus for sintering at a temperature of 350 ° C with ashes in order to obtain HOC3O (804) 3 necessary for carrying out the process of separating sulfuric anhydride from the absorption solution of ammonium sulphite-bisulphite. This regenerates ammonia, which is recycled to absorb sulfur dioxide.
Конечными продуктами очистки газов по предлагаемому способу вл ютс : 100%-ный сернистый ангидрид, который может быть подвергнут в цел х транспортабельности, и полупродукт дл производства чистого сернокислого алюмини и чистой окиси алюмини .The final gas cleaning products of the proposed method are: 100% sulfuric anhydride, which can be subjected to transportability, and intermediate products for the production of pure aluminum sulphate and pure alumina.
Предлагаемый способ очистки имеет р д существенных преимуществ перед примен емыми в промыщленности способами регенерации сульфнт-бисульфнтных растворов, получаемых при аммиачно-циклическом способе газов от сернистого ангидрида (например, при очистке дымовых газов эл.ектростанций).The proposed purification method has a number of significant advantages over the methods of regeneration of sulfnt-bisulfonate solutions used in the industry, obtained from the ammonia-cyclic method of gases from sulfuric anhydride (for example, when cleaning the flue gases of electric power stations).
а)данный способ не требует расхода аммиака, так как он регенерируетс при спекании шихты из золы и сульфата аммони ;a) this method does not require the consumption of ammonia, since it is regenerated during sintering the mixture of ash and ammonium sulfate;
б)не требует охлаждени газов ниже 65°;b) does not require cooling gases below 65 °;
в)не требует глубокой очистки дымовых газов от золы перед поступлением в абсорбер;c) does not require deep cleaning of flue gases from ash before entering the absorber;
jvjb 05906-2г ) позвол ет сократить колитество примен емой аппаратуры (скрубберов , градирса) и уменьшить габариты абсорберов (из-за большей ш;елочпости примен емых растворов).jvjb 05906-2d) allows to reduce the amount of equipment used (scrubbers, cooling towers) and reduce the dimensions of the absorbers (due to the greater w; the strength of the solutions used).
Предлагаемый способ может быть применен на электростанци х при очист1се дымовых газов, на предпри ти х цветной металлургии дл очистки ОТХОДЯШ.ИХ газов: шахтиых и отражательных печей, на предпри ти х черной металлургии дл очистки газов агломерационных фабрик и .в других случа х, когда требуетс очистка газов от сернистого ангидрида.The proposed method can be applied at power plants during the purification of flue gases, at non-ferrous metallurgy enterprises for purification of WASTE OF THEIR gases: shaft and reflection furnaces, at ferrous metallurgy enterprises for purifying gases of sinter plants and in other cases when gas purification from sulfuric anhydride is required.
