The invention relates to a technique for the purification of liquids and can be used in the petroleum, petrochemical, and petroleum refining industries when removing petroleum products, mechanical impurities, and associated gases from reservoir gas.

The purpose of the invention is to reduce energy consumption, as well as improve the degree of purification and degassing of a liquid.

The drawing shows schematically the proposed device for cleaning liquid.

The device contains a flotation chamber 1, a means for creating a vacuum in the form of a vertical tank 2. The flotation chamber 1 has nozzles 3 and 4 inlets and liquid outlets nozzles 5-7 of foam, gas and sludge outlet, and a foam remover 8. The nozzle 3 is filled as installed along the axis in the bottom of the chamber 1 stand 9 and the radially arranged pipes 10 connected to it with blocked free ends 11 and perforations 12 in the upper part. This makes it possible to disperse the liquid from the bottom up evenly over the cross section of the hydrostatic column. The pipe 4 is made in the form placed in the chamber 1 of the tube 13 with the end bent down, under which the partition wall 14 is installed.

The means for creating a vacuum is provided with a horizontal partition 15 having vertical pipes 16, which are equally spaced around the circumference. This placement of pipes in the partition 15 provides uniform bubbling of gas in a liquid over the cross section of the tank.

The upper part of the tank 2 is connected to the gas outlet nozzle 6 by means of the pipeline 17, and a pipe 18 is installed inside the tank above the horizontal partition 15, which is connected to the nozzle 4 of the liquid outlet

In the tank 2 is installed the outlet pipe 19 of the foam with foam collector 20 above the lower edge of the vertical pipe 16. The container 2 is equipped with an outlet pipe 21 of the liquid; located in the lower part of the tank above the lower edge of the vertical pipes 16, the outlet nozzle 22 of the gas placed in the upper part below the partition 15, and the outlet nozzle 23 of the sludge installed in the bottom of the tank. The outlet pipe 21 has a tube 24 with an end bent down, under which the partition wall 25 is installed.

The liquid purification device operates as follows.

The gas-impermeable mixture under pressure is supplied through one hundred to nine. And pipes 10 to the flotation cell 1. As a result of a sharp decrease in pressure at the exit of the mixture of perforations 12 of the pipes 10, there is an intensive release of tiny bubbles of dissolved gas in it. When emerging, these puffs capture particles of solid and liquid impurities, creating a foam on the surface of the liquid column. The latter is collected in the foam remover 8 and is discharged from chamber 1 through pipe 5, and the gas discharged from the liquid through pipe 6 is sent to vertical container 2 B. The liquid purified and degassed in the flotation chamber 1 flows through pipe 18 to the pipe the wall 15, from where it flows down through the pipes 16, entrains the gas and creates a continuous suction of the latter from the flotation cell 1. When the liquid is dropped in the pipes 16, the interfacial contact surface is continuously renewed as a result of repeated shredding This is caused by the release of dissolved gas from the liquid after flotation.

Due to the fact that solid and liquid impurities are kinetic, the energy of the falling droplets is much more than the liquid droplets are drained from the main pressure of the hydrostatic stolbane mass and through the end 21 of the liquid outside the pipes above the lower and cleaned and degassed edges, the liquid column in pipes:, the liquid leaves the container 2. Foam is absent. From the pipes 16, gas and fuel cells in the vessel 2 on the bottom flow into the liquid, the liquid-gas interface, where the phase inversion occurs, is attached to the foam collector 20 and this gas bubbles as a bubble through the pipe 19. on the surface of the liquid, carried away by the weapon.
