Claims (1)

Способ улавливания паров металлов и их соединений из отходящих газов металлургических агрегатов, в котором поток отходящих газов приводят в газоходе в прямой контакт с охлаждающей средой, отличающийся тем, что в качестве охлаждающей среды применяют твердые частицы, имеющие температуру ниже температуры десублимации улавливаемых паров, которые вводят в верхнюю часть газохода в месте, где температура отходящих газов выше критической температуры десублимации улавливаемых паров, частицы под действием силы тяжести пропускают через поток отходящих газов, десублимируя на них улавливаемые пары, далее собирают частицы в нижней части газохода, охлаждают и снова вводят в газоход, при этом размер твердых частиц выбирают из условия, что расчетная скорость взвешенного состояния частиц больше скорости потока отходящих газов в газоходе в месте ввода частиц.A method for capturing metal vapors and their compounds from exhaust gases of metallurgical units, in which the exhaust gas stream is brought into direct contact with the cooling medium in the duct, characterized in that solid particles are used as the cooling medium, having a temperature below the temperature of desublimation of the captured vapors that introduce in the upper part of the duct in a place where the temperature of the exhaust gases is higher than the critical temperature of desublimation of the trapped vapors, particles under the influence of gravity are passed through a stream o of flue gases, desublimating the trapped vapors on them, then collect particles in the lower part of the flue, cool and re-introduce into the flue, while the size of the solid particles is chosen from the condition that the calculated particle velocity is greater than the velocity of the exhaust gases in the flue at the particle inlet .
