Claims (4)

1. Способ обработки отходящего газа путем воздействия на него электронными лучами, включающий добавление аммиака к отходящему газу, содержащему окислы серы (SOx) и/или окислы азота (NOx) и после этого воздействие на газ электронным лучом для того, чтобы удалить окислы серы и/или азота из него, отличающийся тем, что сначала равномерно смешивают газообразный аммиак с воздухом, затем образуют гомогенную газожидкостную смесь из газовой смеси и воды и вбрызгивают гомогенную смесь в реактор.1. A method of treating exhaust gas by exposure to electron beams, comprising adding ammonia to the exhaust gas containing sulfur oxides (SO x ) and / or nitrogen oxides (NO x ) and then subjecting the gas to an electron beam in order to remove oxides sulfur and / or nitrogen from it, characterized in that at first the gaseous ammonia is uniformly mixed with air, then a homogeneous gas-liquid mixture is formed from the gas mixture and water and the homogeneous mixture is sprayed into the reactor. 2. Способ по п.1, отличающийся тем, что отношение воды к газовой смеси газообразного аммиака и воздуха находится в диапазоне от 0,1 до 20 л/м3, количество аммиака в газовой смеси находится на уровне, необходимом для преобразования окислов серы и/или окислов азота в газовой смеси в сульфат аммония и/или нитрат аммония, соответственно, и количество воды находится на уровне, необходимом для регулирования температуры отходящего газа на выходе реактора, в диапазоне температур от точки росы воды до не более 100oC.2. The method according to claim 1, characterized in that the ratio of water to gas mixture of gaseous ammonia and air is in the range from 0.1 to 20 l / m 3 , the amount of ammonia in the gas mixture is at a level necessary for the conversion of sulfur oxides and / or nitrogen oxides in the gas mixture into ammonium sulfate and / or ammonium nitrate, respectively, and the amount of water is at the level necessary to control the temperature of the exhaust gas at the outlet of the reactor, in the temperature range from the dew point of water to not more than 100 o C. 3. Способ по п.1 или 2, отличающийся тем, что температуру трубопровода поддерживают при 60oC или выше в течение промежутка времени от смешивания газообразного аммиака с воздухом до смешивания полученной смеси с водой для образования газожидкостной смеси.3. The method according to claim 1 or 2, characterized in that the temperature of the pipeline is maintained at 60 o C or higher for a period of time from mixing gaseous ammonia with air to mixing the resulting mixture with water to form a gas-liquid mixture. 4.
