Abstract: An active strainer contains a housing with a cover, a base and side surfaces made in the form of filtering elements, pipes with channels fixed at one end at the central vertical axis of the strainer and configured to supply purified fluid from the central part of the strainer to the filtering elements from the other end of the pipe through channels, wherein the strainer housing is made of two parts, an upper and a lower one, each part is equipped with at least one filtering element, the turbine is installed between the upper and lower part and configured to rotate during the fluid flow passage through it, the turbine shaft is connected with the pipes, which are capable of sampling the purified fluid from the strainer housing during rotation of the turbine.

Abstract: The group of inventions refers to heat exchange machinery. The device includes a tank with an outlet fitting and a steam source, a deaerator column with a cover and water inlet and vapor blowdown fittings located on the same, containing lower and upper deaeration sections. Each section includes pressure and distribution trays forming a jet chamber in the space between them, and random element packing. Deaeration sections are separated by a hydraulic seal formed by the edge of the upper section pressure tray and the projection connected to the deaerator column cover. The water inlet and vapor blowdown fittings are located inside the hydraulic seal projection with openings in it. The lower edges of the openings are located higher than the upper edge of the hydraulic seal by a value exceeding the sum of overflow height of the coolant over the edge and hydraulic resistance of the hydraulic seal channel.
