Description

The invention relates to water supply, for the structural design of a device for water intake from a surface source, providing preliminary clarification of water in the place of its intake.

The purpose of the invention is to increase the efficiency of clarification of water.

The drawing shows a floating water intake-clarifier, General view.

The floating water intake-clarifier consists of a water-lifting installation 1 in the form of installed wear with a discharge line 2, pivotally connected to a discharge pipe 3, and a suction line 4, a clarifier 5, which is a thin-layer module 6 in the form of a package of inclined elements, above which a drainage tank 7 is placed , and from the vertical partitions 8. located under the module 6. In the catchment tank 7 there is a water intake manifold 9 made in the form of perforated pipes with a variable duty cycle. The drainage tank 7 installed in it by the vertical transverse partitions 10 is divided into compartments 11, communicating with the outlet holes of the thin-layer module 6, while the partitions 10 are placed one from the other with a decrease in the distance from the periphery to the suction line, and the perforated pipes within the compartment have a duty cycle, also decreasing from the periphery to the suction line.

Floating water-illuminator works as follows.

When starting up the water-lifting installation 1, water from the source 12 through the cells 13 formed by the vertical partitions 8, stabilizing the flow, enters the inlet holes of the inclined elements of the thin-layer module 6 and through their outlet openings into the drainage tank 7.

Water from the catchment tank 7 is pumped out through the perforated pipes and the suction line 4 by the water-lifting installation 1 and through the discharge line 2 5 flows to the onshore facilities.

Suspended substances deposited on the walls of the inclined elements of the thin-layer module 6 in a continuous flow slide in the opposite direction 10 to the movement of the clarified water, and are carried away by the stream at the exit from the elements.

The separation of the catchment tank by vertical transverse partitions eliminates the flow of water in the horizontal 15 direction and ensures its radial movement to the corresponding sections of the perforated pipes, while the uniformity of inflow to them within each compartment is provided by a decreasing 20 duty cycle of the section of perforated pipes in the direction from the periphery to the suction line.

The invention provides the ability to control the hydraulic loads of all elements of the system regardless of where the suction line is connected to the intake manifold - symmetrically or asymmetrically.

Claims (1)

The formula of the invention 30 Floating water intake-clarifier No. 885466, characterized in that, in order to increase the efficiency of the process of clarifying water, the catchment tank is equipped with 35 transverse partitions installed in it with the formation of compartments communicating with the outlet openings of thin-layer elements, while the transverse partitions are placed one from another with decreasing distance 40 from the periphery to the suction line, and the per-. the formed pipes within the compartment have a duty cycle that also decreases from the periphery to the suction line.
