FIELD: oil-producing industry; agriculture; other industries; device for purification of the oily waste waters of the oil fields. ^ SUBSTANCE: the invention is pertaining to the equipment intended for purification of the oil-polluted waste waters of the oil fields and may be used in other industries, for example, in agriculture etc., which waste waters contain the oil and oil products. The device contains hydrocyclones, on the outlets of the upper and lower drains of which there are the cylindrical chambers with the pressure-tight tubular rings. The rings are joined by the pipeline-jumper)with two slide valves. The waste water feeding pipeline is connected to the jumper by the by-pass pipeline having the screw-type channel inclined to the pipeline axis. The additional pipelines are supplied with the slide valves. The technical result of the invention consists in the increased reliability of the device operation, the capability of disconnection and actuation of the group of the hydrocyclones with the cylindrical chambers of the upper and lower drains without the complete disconnection of the device. ^ EFFECT: the invention ensures the increased reliability of the device operation, the capability of disconnection and actuation of the group of the hydrocyclones with the cylindrical chambers of the upper and lower drains without the complete disconnection of the device. ^ 2 dwg |
