Abstract
СПОСОБ ОЧИСТКИ ОТХОДЯЩИХ ГАЗОВ ОТ ДВУОКИСИ СЕРЫ путем поглощени водной суспензией фосфорита, отличающийс тем, что, . с целью упрощени процесса при сохранении сорбционной емкости фосфорита , процесс ведут в кип щем слое при скорости газов 4,5-6,0 м/с, температуре 120-200 с и соотношении Т:Ж в суспензии 1:(О,15-0,20). (ЛA method for purifying waste gases from sulfur dioxide by absorption in an aqueous suspension of phosphorite, characterized in that,. in order to simplify the process while maintaining the phosphorite sorption capacity, the process is carried out in a fluidized bed at a gas velocity of 4.5-6.0 m / s, a temperature of 120-200 s and a T: W ratio in suspension 1: (O, 15-0 ,20).

содержащего 0,2% , подают в аппарат кип щего сло КС, где двуокись серы, поглощаетс 68 г фосфорита, содержащего 28% и 2% MgO. Количество подаваемой воды на увлажнение фосфорита - 10,2 кг. Процесс ведут при |20°С, скорости газа 4,5 м/с в течение 30 мин. Очищенный от SOj газ выбрасьгаают в атмосферу, обработанный фосфорит в количестве 73,0 кг направл ют на переработку в суперфос.containing 0.2%, is fed to the fluidized bed apparatus KS, where sulfur dioxide is absorbed 68 g of phosphorite containing 28% and 2% MgO. The amount of water supplied to hydrate phosphate - 10.2 kg. The process is conducted at | 20 ° C, gas velocity of 4.5 m / s for 30 minutes. The gas purified from SOj is emitted into the atmosphere, and the treated phosphorite in the amount of 73.0 kg is sent for processing to superphos.
