Abstract

Сущность изобретени : газ, содержащий пары ртути, пропускают через железо- марганцевые конкреции.The essence of the invention: gas containing mercury vapors is passed through iron-manganese nodules.

Description

Изобретение относитс  к способам очистки газов от паров ртути и может быть использовано дл  санитарной очистки воздуха и отход щих газов ртутного производства.The invention relates to methods for the purification of gases from mercury vapors and can be used for the sanitary purification of air and waste gases of mercury production.

Целью изобретени   вл етс  повышение степени очистки газов от ртути.The aim of the invention is to increase the degree of purification of gases from mercury.

П р и м е р 1. Газовую смесь, состо щую из воздуха, предварительно насыщенного парами ртути до концентрации 2 мг/м3, пропускают со скоростью 1 л/мин через стекл нную колонку диаметром 10 мм, в которую помещено 2 г железомарганцевых конкреций фракции -0,25 - +0,1 мм. На выходе из колонки воздушную смесь анализируют на содержание ртути атомно-флюоресцентным методом. После пропускани  100 м газовой смеси обнаружен проскок 0,01-0,02 мг/м3 ртути. Степень очистки составл ет 99%.EXAMPLE 1 A gas mixture consisting of air, pre-saturated with mercury vapor to a concentration of 2 mg / m3, is passed at a rate of 1 l / min through a 10-mm-diameter glass column containing 2 g of ferromanganese nodules of the fraction -0.25 - +0.1 mm. At the outlet of the column, the air mixture is analyzed for mercury content by the atomic-fluorescent method. After passing 100 m of the gas mixture, a breakthrough of 0.01-0.02 mg / m3 of mercury was detected. Purification rate is 99%.

П р и м е р 2. Газовую смесь, состо щую из воздуха, насыщенного парами ртути доPRI mme R 2. A gas mixture consisting of air saturated with mercury vapor to

концентрации 20 мг/м , пропускают со скоростью 0,5 л/мин через стекл нную колонку диаметром 10 мм, в которую помещено 2 г железомарганцевых конкреций, измельченных до фракции -0,25 - +0,1 мм После пропускани  10 м3 газовой смеси обнаружен проскок 0,02 мг/м3. Степень очистки составл ет 99,9%.concentrations of 20 mg / m are passed at a rate of 0.5 l / min through a glass column with a diameter of 10 mm, into which 2 g of ferromanganese nodules are placed, crushed to a fraction of -0.25-0.1 mm. After passing 10 m3 of gas A leakage of 0.02 mg / m3 was detected. The degree of purification is 99.9%.

Емкость железомарганцевых конкреций по ртути 1,0-1,2 мг/г. емкость сорбента по прототипу 0,8-0,9 мг/г.The capacity of ferromanganese nodules for mercury is 1.0-1.2 mg / g. the capacity of the sorbent prototype 0.8-0.9 mg / g
