Abstract: Изобретение относится к машиностроению и, в частности, к регенерации отработанных масел. Цель изобретения - получение качественных масел с содержанием следов воды без дополнительного разделения сбора масел по типам. Способ очистки отработанного масла включает процессы фильтрации, нагрева, предварительной очистки с отстаиванием масла, удалением воды и перемешиванием оставшегося масла, а также процессы центрифугирования, дальнейшего нагрева, сепарирования и вывода полученных масла и воды. Новым в способе является воздействие на него деэмульгаторами перед сепарированием и после него, охлаждение его до температуры 50-75 o C, воздействие на него электрическим полем в две стадии со снижающейся напряженностью и временем воздействия электрического поля 45-300 o C в зависимости от состава масла.

Inside the latter, parallel to prism faces, a shaft is mounted with fastened and perpendicular to it blade holders. Blades are fixed at and angle to holder rotation circle tangent. Inside casing, pipes with holes for air feeding are disposed parallel to edges of prism. Number of faces of prism is determined by formula: n = K-a/b where a is distance from bottom of casing to its shaft axis, m; b width of casing, m; and F experimentally found coefficient of proportionality. Blade holders are installed by groups in clasping clutches uniformly in relation to rotation axis, holders in each subsequent groups being shifted relative to preceding ones at angle at least 30 deg. Blades are fixed on opposite holders with shift relative to holder equal to 1/3 blade length toward opposite sides, and adjacent blades are fixed symmetrically in respect to axis of holder.
