HYDRODYNAMIC CORRECTOR OF STREAMS OF LIQUIDS Russian patent published in 2005 - IPC

FIELD: chemical and petroleum refining industry; production of devices for a dispersion, homogenization and mixing of streams of liquids.

SUBSTANCE: the invention is dealt with devices for a dispersion, homogenizations and mixings of streams of liquids and may be used for intensification of technological processes in petroleum refining industry, chemical and other industries and also for homogenized treatment of heavy petroleum kinds of fuel used in industries and heat power engineering. The hydrodynamic corrector of streams of liquids contains a body 1 with an inlet branch-pipe 2 and an outlet branch-pipe 3. Inside the body 1 there are: a distributor 4 made in the form of a disk with holes 5 and installed with a capability to overlap a working chamber of the body 1 and a tool to provide a speed-up of the treated stream made in the form of a disk 7 with a through conical hole. The distributor 4 has a dome 8. Inside the hydrodynamic corrector in the zone of the outlet branch-pipe 3 there are an emitter 9 with crescent blades 10 and a disk 11 with a through hole installed in the zone of the outlet branch-pipe with a capability to form a cylindrical chamber 12. The distributor 4 with the dome 8 and the disk are located from each other with a capability of formation of a ring channel 13. The emitter 9 dressed on 11 disk 7 are located in respect to each other with a capability to form a ring-shaped channel 13. The emitter 9 is fixed on the disk 11 with a capability to form a zone of mixings 20. Through the inlet branch-pipe 2 the treated stream of a liquid is directed inside the body 1 and through holes 5 of the distributor 4 is directed into the ring-shaped channel 13. Due to contraction of the passing cross-section of the ring-shaped channel the speed of the stream increases and the pressure drops. At the channel outlet the stream runs onto a deflector 14. At the expense of it in the ring-shaped groove 16 a toroidal vortex cavitation zone is formed. Then the stream is rejected into the chamber 6. Then moving in the chamber 6 the stream falls in a conical hole of a booster. Because of a contraction of the passing cross-sections the speed of the stream increases and pressure drops. The stream of liquid coming out of the hole of disk runs onto the deflecting surface 18 of the emitter 9 made in the form of a spherical pit and being deflected from it forms a toroidal vortex cavitation zone again. After that the stream is thrown out into the chamber 19 and moving through it falls through blade-shape vanes into a zone of mixing 20 and then at an acute angle - onto walls of vanes 10, due to that transformation of the treated stream energy into the energy of acoustical oscillations of a broad spectrum is ensured. Under action of the acoustic oscillations in the stream a zone of an acoustic cavitation is formed. In this connection the stream from a cylindrical hole of the disk falls into the chamber. In the chamber the braking of the stream takes place and due to that the final treatment of the stream is ensured, that is appearance of the cavitation bubbles into the outlet branch-pipe 3 is prevented. The technical result is an increase of a degree of dispersion and homogenization of a treated stream.

EFFECT: the invention ensures an increased degree of a dispersion and homogenization of a treated stream.
