Description
инертного материала, котора становитс безопасной даже при наличии инициатора воспламенени (огневые работы).an inert material that becomes safe even in the presence of an igniter (fire work).
Схема Осуществлени предлагаемого способа представлена на чертеже.Scheme Implementation of the proposed method is presented in the drawing.
Аппараты технологической системы 1, 2 и 3 соединены трубопроводами с .машиной 4 дл загрузки пылевидных инертных материалов . Машлна подсоединена к трубопроводу 1ннертного газа с давлением 2 ати. Перед ремонтом систел5ы в машину 4 подают инертный газ. Газом инертный материал в количестве не менее 0,2% от объема заполненной системы из машины 4 подаетс по трубопроводам в аппараты /-3. Скорость подачи инертного материала должна быть меньше или равна скорости питани частицы |Инертного матерИала. Инертный материал оседает в апаратах /-3 и трубопроводах , соедин ющих их. В результате образуетс механическа смесь, безопасна да/ке при наличии инициатора воспламенени .металлического порошка , и инертного .матеРиала .The apparatus of the technological system 1, 2 and 3 are connected by pipelines with a machine 4 to load dust-like inert materials. The machine is connected to a pipeline with a pressure of 2 bar. Before repairing, the systel5y is supplied with inert gas. Gas inert material in an amount of not less than 0.2% of the volume of the filled system from the machine 4 is fed through pipelines to the apparatus / -3. The feed rate of the inert material must be less than or equal to the feed rate of the particle | Inert material. Inert material is deposited in the apparatus / -3 and the pipelines connecting them. As a result, a mechanical mixture is formed, a safe yes / ke in the presence of an initiator of ignition of the metal powder, and an inert material.
Подача инертного материала производитс тем же газом, в котором ведетс процесс получени порошка.The inert material is supplied by the same gas in which the powder is produced.
Предлагаемый способ обеспечивает полнзю безопасность лодготовительных работ, самого ремонта технологических систем с огневыми работами, хорошую очистку внутренних иоверхностей аппаратов системы от металлической пыли, возможность простого Здалени продуктов очистки из системы.The proposed method ensures the full safety of the water preparation works, the very repair of technological systems with hot work, good cleaning of the internal and surfaces of the apparatus of the system from metallic dust, the possibility of simple building of cleaning products from the system.
