Abstract: Изобретение относится к технике мокрого пылеулавливания и может применяться в химической, текстильной, пищевой, легкой и других отраслях промышленности для очистки запыленных газов. Способ очистки воздуха заключается в том, что загрязненный газовый поток подают через входной патрубок, расположенный в корпусе, причем один из срезов патрубка располагают с зазором над зеркалом жидкости, находящейся в резервуаре, и создают псевдокипение жидкости с образованием газожидкостной взвеси. Затем отводят газожидкостную взвесь в сепаратор жидкой фазы, освобождают газовый поток от капель жидкости и отводят его через выходной патрубок, а образовавшийся шлам отводят через трубу, расположенную на дне корпуса. Загрязненный газовый поток подают через цилиндрический патрубок, в верхних слоях жидкости размещают вибратор и закрепляют его к корпусу посредством упругой перфорированной мембраны, а образование газожидкостной взвеси дополнительно усиливают созданием виброкипящего слоя в верхних слоях жидкости. Устройство для очистки воздуха содержит корпус, патрубок для ввода запыленного газа и патрубок для выхода очищенного газа, резервуар с жидкостью, смывное сопло и трубу для отвода шлама, при этом патрубок для ввода запыленного газа выполнен цилиндрическим, а в верхних слоях жидкости размещен вибратор, закрепленный к корпусу посредством упругой перфорированной мембраны.
