(54) СПОСОБ ОЧИСТКИ ГАЗОВ ОТ СЕРНИСТОГО АНГИДРИДА(54) METHOD FOR CLEANING GAS FROM SULFUR ANHYDRIDE
1one
Изобретение относитс к области очистки отход щих газов от примесей сернистого ангидрида , в особенности выхлопных газов контактного сернокислотного производства.The invention relates to the field of purification of waste gases from sulfuric anhydride impurities, in particular the exhaust gases of contact sulfuric acid production.
Известен способ очистки газов от сернистого ангидрида путем абсорбции последнего раствором серной кислоты, предварительно подвергнутым электролизу.A known method of cleaning gases from sulfur dioxide by absorption of the latter with a solution of sulfuric acid, previously subjected to electrolysis.
Однако такой способ имеет недостаточно высокую степень очистки газа от сернистого ангидрида (до 75%).However, this method has an insufficiently high degree of gas purification from sulfuric anhydride (up to 75%).
С целью повышени степени очистки газа от сернистого ангидрида в раствор перед электролизом ввод т ионы марганца.In order to increase the degree of gas purification from sulfuric anhydride, manganese ions are introduced into the solution before electrolysis.
Предложенный способ позвол ет повысить степень очистки газа от S02 до 99%.The proposed method allows to increase the degree of gas purification from S02 to 99%.
Пример. В абсорбционную башню подают 10000 отход щего газа с содержанием 0,2-0,3 об. % SOg. Башню орошают 30%ным раствором серной кислоты, куда ввод т ионы марганца в количестве 0,05%.Example. 10,000 waste gas is fed into the absorption tower with a content of 0.2-0.3 vol. % SOg. The tower is irrigated with a 30% solution of sulfuric acid, where manganese ions in the amount of 0.05% are introduced.
Расход раствора на орошение составл ет 100 при кратности циркул ции, равнойThe consumption of the solution for irrigation is 100, with a circulation ratio equal to
15. Обш,ий объем поглотительного раствора составл ет 7 м. Часть раствора в количестве 5 (5% от общего расхода) перед подачей в абсорбционную башню пропускают через электролизер дл активации катализатора - ионов марганца.15. The total volume of the absorption solution is 7 m. A part of the solution in the amount of 5 (5% of the total consumption) is fed through an electrolyzer to activate the catalyst — manganese ions, before being fed into the absorption tower.
Электролиз ведут при температуре 20-30°С, анодной плотности тока 100-500 а/м катодной плотности тока 500-1500 а/м, нацр жение на электролизере 2,5-3,0 В, остаточное содержание SOg в газе после очистки составл ет 0,002-0,003 об. % (т. е. степень очистки 99%).Electrolysis is carried out at a temperature of 20-30 ° C, anodic current density of 100-500 a / m cathode current density of 500-1500 a / m, the national concentration on the electrolyzer is 2.5-3.0 V, the residual content of SOg in the gas after cleaning is em 0,002-0,003 about. % (i.e., purity 99%).
