Abstract

The invention can be used in the petroleum, oil refining, chemical, gas and other industries. The aim of the invention is to improve the quality of water purification. The flotation cell contains a vertical tank, with nozzles of liquid inlet and gas outlet, foam product and gas outlet, a collector, horizontal partitions (GP) with openings into which vertical pipes (VT) are inserted, the lower portions of which are located below the GP and are perforated, foam receivers product in the form of vertical nozzles with expansion in the upper part, vertical cylindrical partitions installed in the collector holes, vertical nozzles, cups, vertical pipe with vertical cylindrical partition and cup. Perforation of the lower portions of the VT provides gas with a descending liquid flow, which leads to a more complete enrichment of the liquid with gas. 1 pe.

Description

The invention relates to devices for the treatment of waste and natural waste systems used in the petroleum, oil refining, petrochemical, - X | Ymic, gas and other industries. x industryJi is improved by the valuation of a flotation machine by auth.St. And 1318975.

Invention of the invention is an increase in the quality of purification by increasing the amount of gas in the treated volume of water.

: The figure shows the proposed flotation plant. .

: The flotation cell contains vertical capacity 1 with nozzles of inlet 2 and outlet 3 of liquid, output of foam product 4 and gas 5, collector 6, horizontal partitions 7 with holes 8 and receivers of foam product made in the form of centrally located in tank 1 each under other vertical nozzles 9 with an extension of 10 at the top. In the openings In the horizontal partitions 7 vertical pipes 11 are mounted, the upper end of which is located below the upper end of the nozzle 9 of the common horizontal: horizontal partition, and the lower end is above the upper end of the vertical pipes of the lower horizontal partition.

At the upper end of each vertical pipe 11, a cylindrical partition 12 is installed coaxially vertical, the upper end of which is located above the upper end of the pipe 9, and the lower end is below the upper end of the vertical pipes of a common horizontal partition 7.

In the holes 13 of the collector 6 mounted nozzles 14, the lower end of which is installed below the upper ends of the vertical pipes 11 of the upper horizontal partition 7.

On each pipe 11, below the vertical cylindrical partition 12, a cup 15 is installed with a diameter exceeding the diameter of this partition.

To pipe the outlet of the liquid 3 is attached installed in the tank 1 vertical pipe 16, the upper end of which is located below the upper end of the lower vertical pipe 9, and this pipe is equipped with a vertical cylindrical partition 17 and a cup 18..

A hatch 19 is installed on the tank to remove the Ilem from the upper partition 12.

The section of vertical pipes 11, located under horizontal partition walls 7, is made with perforations 20.

The flotation cell works as follows.

The gas source gas mixture is supplied under pressure to the tank 1 through the pipe 2 and through the manifold 6 is distributed to

5 separate equal flows, which are directed along the vertical nozzles 14 into the treated volume of the upper horizontal partition 7. At the outlet of the initial mixture flows from Pat0 Rubkov 14, there is a release from

this mixture of the smallest bubbles of dissolved gas. As the gas bubbles rise, they capture solid and liquid impurities, creating foam on the surface of the volume being processed. The clarified liquid from the upper horizontal septum 7 is poured over pipes 11 to the lower horizontal septum, and

0 The foam product accumulates on the surface of the volume to be treated. When the level of foam product on the surface of the processed volume of the upper partition 7 exceeds the upper edge of the pipe 9 of this partition, the upper receiver of the froth product will drain.

The penetration of foam and gas bubbles into the pipes 11 is excluded because the upper end of the vertical cylindrical partitions 12 is located above the nozzle 9, and the lower end is below the upper end of the pipes 11 of the general bulkhead 7 and is covered with cups 15,

In the process of downward movement through pipes 11, the liquid draws gas into a joint movement both through the upper edge and through perforations.

20.

At the exit vi3 of the pipes 11, the gas-liquid flow, having a large kinetic energy, penetrates the volume of the downstream partition 7, being processed,

The process then repeats. The finally clarified liquid exits.

from the tank 1 through the pipe 3, and the froth product is removed through the pipe 4. The gas is released through the pipe 5.

The proposed device allows improving the quality of cleaning by more complete enrichment of the liquid with air.
