Способ относится к технологии снижения загрязнения окружающей среды и улучшению условий труда, в частности к способам снижения концентрации экологически вредных веществ, образующихся при работе установок плазменной обработки материалов. Снижение концентрации экологически вредных веществ в отходящих газах достигается за счет предотвращения образования этих веществ. Для этой цели в установке плазменной обработки размещают специальный формирователь, через который пропускают инертный газ и создают ламинарный поток, полностью окружающий плазменную струю. Расход инертного газа устанавливают превышающим эжекционный расход плазменной струи. Способ обеспечивает существенное снижение концентрации оксидов азота и озона в отходящих газах установки плазменной обработки.The method relates to a technology for reducing environmental pollution and improving working conditions, in particular, to methods for reducing the concentration of environmentally harmful substances produced during the operation of plasma processing plants. Reducing the concentration of environmentally harmful substances in the exhaust gases is achieved by preventing the formation of these substances. For this purpose, a special shaper is placed in the plasma treatment installation, through which an inert gas is passed and a laminar flow is created that completely surrounds the plasma jet. The flow rate of the inert gas is set in excess of the ejection flow rate of the plasma jet. The method provides a significant reduction in the concentration of nitrogen oxides and ozone in the exhaust gases of the plasma treatment unit.
