Description

one

The invention relates to devices for separating two immiscible liquids with different specific weights, and more specifically to devices for flotation purification of water from emulsified oil, and can be used in the petroleum and petroleum refining industries.

The closest in technical essence and the achieved result to the proposed is a flotation cell comprising a housing, supply pipes for supplying the source and removal of purified water and foam, a distributor of air saturated with water placed in the flotation chamber 1.

The disadvantages of the known technical solution are the low efficiency of the device and the insufficiently high quality of cleaning, since the sizes of gas bubbles are larger than the sizes of droplets of emulsified oil.

In order to eliminate these drawbacks, the proposed flotation cell is provided with a mesh partition placed in the lower part of the body above the source water supply port and a coalescing nozzle, the bottom of the flotation chamber is made mesh, and the coalescing nozzle is placed between the mesh partition and the bottom of the flotation chamber.

The drawing shows a General view of the flotation cell.

The flotation cell includes a housing 1, a flotation chamber 2 bounded by a cylindrical vertical partition 3, a distributor 4 of circulating air saturated with water placed in the lower part of the flotation cell 2, a settling compartment 5, an annular perforated collector 6 for draining purified water and a lifting pipe 7, device 8 for removal of foam. The bottom 9 of the flotation cell is mesh and the volume between the bottom and the mesh partition 10 is filled

coalescing load 11. Moreover, the water distributor 4 is installed above the bottom 9, the pipe 12 for supplying the source water - under the mesh partition 10.

The housing is also equipped with connections for

supplying recirculated water 13, discharging foam 14 and air 15. The mesh partition 10 with the bottom wall of the housing 1 forms a receiving chamber 16, with which the outlet 12 of the source water supply communicates.

The device works as follows.

The source water through the pipe 12 is fed into the receiving chamber 16, from where it is through the coalescing load 11, which simultaneously serves as a distributor for

Claims (1)
