STAND FOR FLUSHING HYDRAULIC SYSTEMS WITH A MIXTURE OF LIQUID AND COMPRESSED GAS Russian patent published in 2022 - IPC B08B9/32 

FIELD: power engineering.

SUBSTANCE: invention relates to the field of power engineering, in particular to devices for flushing the loop systems of steam generating plants. The stand for flushing hydraulic systems with a mixture of liquid and compressed gas contains a compressed gas preparation unit, an injection line that includes liquid and compressed gas supply lines connected to the mixer through a pressure tank, a drain line equipped with a drain tank and devices for separating compressed gas and purifying liquid, according to invention, the liquid pressure line and the compressed gas supply line are connected to the mixer, while the compressed gas supply line is made of U-shaped pipes with an inner diameter of not more than 150 mm, installed vertically and connected in series in the form of a parallelepiped-shaped battery, and into each the pipe is equipped with a filter block with a set of plates with a thickness of not more than 10 mm, having holes for the passage of compressed gas with an angular displacement of 60° relative to each adjacent plate and a distance between the plates of 15÷20 mm, and a filter block with activated filler, while the pipes with each types of filter units are installed in turn, and at the mixer, the housing is made in the form of a tee, having an internal angular pipeline for supplying compressed gas, which is inserted into the cavity of the tee housing through an angular or perpendicular hole with respect to the coaxial holes of the tee, and at the end of the angular pipeline located in the internal cavity of the tee, a hydraulic turbine with internal channels passing through the center of rotation and each blade with the direction of the outlet part of the channels perpendicular and opposite to the direction of rotation of the turbine.

EFFECT: ensuring intensive and high-quality washing of products.
