Claims (25)
(а) сжатие газа до давления выше атмосферного;
(в) подачу сжатого газа в реактор (83) с псевдоожиженным слоем и напорный котел (82) при давлении внутри напорного котла выше атмосферного;
(с) проведение химических реакций, идущих в реакторе с псевдоожиженным слоем при давлении выше атмосферного для образования горячих загрязненных газов, содержащих газообразные загрязнения, включая окислы азота, и макрочастицы;
(d) при поддержании давления на уровне выше атмосферного транспортировку загрязненных газов в сепаратор для отделения частиц от загрязненных газов в сепараторе с получением чистого газа, и транспортировку газа в газовых расширитель;
(е) в процесс осуществления ступени (d) введение в загрязненные газы восстановителя, отличающийся тем, что ступень (е) осуществляют в одной или более точках между кеком (3) и газовым расширителем.1. A method for cleaning hot polluted gases leaving the pressure fluidized bed reactor system, comprising a fluidized bed reactor (83) inside the first pressure boiler (82), a separator for separating particulate from contaminated gases with filter elements (210, 310, 410, 510, 610, 710), and having a filter surface (2) on the dirty side (4, 24, 34, 44, 54, 65, 74, 74 '), on which cake is formed, and the clean side (5, 25, 35 , 45, 55, 65, 75, 75 ') and a gas expander for expanding the gas after separation of particles from it, including stages:
(a) compression of the gas to a pressure above atmospheric;
(c) supplying compressed gas to a fluidized bed reactor (83) and a pressure boiler (82) at a pressure inside the pressure vessel above atmospheric pressure;
(c) conducting chemical reactions in a fluidized bed reactor at a pressure above atmospheric to generate hot contaminated gases containing gaseous contaminants, including nitrogen oxides, and particulates;
(d) while maintaining the pressure above atmospheric, transporting the contaminated gases to a separator to separate particles from the contaminated gases in the separator to produce pure gas, and transporting the gas to a gas expander;
(e) in the process of step (d), introducing a reducing agent into the polluted gases, characterized in that step (e) is carried out at one or more points between the cake (3) and the gas expander.
