Description

О) О9 Изобретение относитс  к спфобам очистки отход ощх 1фошдвпенных газов от диоксида серы и может быть использовано в химической промышлен ности и в металлургий Целью изобретени   вл етс  расши рение температурного интервала про- ведени  процесса очистки. Пример. Хвосты СОФ, изме ченные до 200 мёш,: прокаливают в му фельной печи при доступе кислорода воздуха. Тигель с содержимым хвостом СОФ став т в муфельную печь. Нагрев до-температуры окислени  производитс  в следукнцем режиме; до 350°С - 1 4} 350-400С - 0,5 ч; вьщержка при 400°С - 1ч; 400500 С - -1 ч; вьщержка. при 300°С 2 ч. . Окисленный сорбент охлаждают. Очистку газа (0,65% диоксида серы) производ т при и объемной скорости подачи очищаемого газа, равной ЭОООС/ч . Степень очистки газов практически полна  при подклю чении в систему трех адсорберов последовательно или слое сорбента, равного сумме высоты слоев адсорбен та в трех реакторах. Пример 2. Сорбент приготав ливают как в примере 1. Очистку газа производ т при (0,65% диоксида серы), объемной скорости газа 9000°С/ч. Степень очистки газов практически полна  при подключе-, НИИ в систему 2 адсорберов последовательно . Пример 3. Сорбент приготавливают как в примере 1. Очистку газа производ т при 500°С (0,65% диоксида серы), объемной скорости газа 9000°С/ч . Степень очистки газов практически полна  при подключении в систему 2 адсорберов последовательно . Пример 4. Сорбент приготавливают как в примере 1. Очистку газа .производ т при 600°С (0,65% диоксида серы), объемной скорости газа 9000С/ч . Степень очистки газов практически полна  при подключении в систему 3 адсорберов последовательно . При дальнейшем повышении температуры в опыте до 700, степень очистки газа снижаетс  резко, т.е. 19 и 16%. В данном способе очистку газа можно проводить в широком температурном интервале (150-800С), так как предлагаемый сорбент карбонатного происхождени , основна  (действующа ) часть сорбента состоит из оксидов щелочноземельного металла, образующихс  в результате предварительной термической обработки, сорбента.O) O9 The invention relates to cleaning methods for the removal of sulfur dioxide dioxide from ground gas and can be used in the chemical industry and metallurgy. The aim of the invention is to extend the temperature range of the cleaning process. Example. SOF tails, measured up to 200 mesh, are: calcined in a muffle oven with the access of oxygen to air. The crucible with the contents of the SOF tail is placed in a muffle furnace. The heating to the oxidation temperature is carried out in the following mode; up to 350 ° С - 1 4} 350-400С - 0.5 h; Extraction at 400 ° С - 1 h; 400500 С - -1 h; overhang at 300 ° C for 2 hours. The oxidized sorbent is cooled. Gas purification (0.65% sulfur dioxide) is carried out at a flow rate of the gas to be purified equal to EOOE / h. The degree of gas cleaning is almost complete when three adsorbers are connected to the system in series or a sorbent layer equal to the sum of the heights of the adsorbed layers in the three reactors. Example 2. A sorbent was prepared as in Example 1. Gas was cleaned at (0.65% sulfur dioxide), gas flow rate 9000 ° C / h. The degree of gas purification is almost complete with the connection of the research institutes to the system of 2 adsorbers in series. Example 3. A sorbent was prepared as in Example 1. Gas was cleaned at 500 ° C (0.65% sulfur dioxide), gas flow rate 9000 ° C / h. The degree of gas cleaning is almost complete when two adsorbers are connected in series to the system. Example 4. A sorbent is prepared as in Example 1. Gas purification is produced at 600 ° C (0.65% sulfur dioxide), the gas flow rate is 9000 ° C / h. The degree of gas cleaning is almost complete when 3 adsorbers are connected in series to the system. With further increase in temperature in the experiment to 700, the degree of gas purification decreases sharply, i.e. 19 and 16%. In this method, gas cleaning can be carried out in a wide temperature range (150-800 ° C), since the proposed sorbent of carbonate origin, the main (active) part of the sorbent consists of alkaline earth metal oxides, formed as a result of preliminary heat treatment, of the sorbent.
