The invention relates to liquid spraying devices ejection type, where the entraining medium is a fluid, ejected environment - gas and can be used for example in power by decarbonization of water, the combustion of liquid fuel in the water when removing ferrous iron from groundwater, oxidation household waste and similar in composition to the water, in the air conditioning when saturated with moisture of the processed air.

Known liquid-gas ejectors Sokolov, E. J., singer N. M. Jet devices, Ed.2-e, M.: Energy, 1970, where working (ejecting) the environment is fluid supplied under pressure to the tapering nozzle outlet from which it gains more speed. When leakage from the nozzle into the intake chamber, a jet of fluid carries with supplied through the pipe receiving chamber or Kolarov, working in various branches of engineering, for example in the energy sector, as vozduhoobrabatyvayushcie device condensing, in schemes vacuum deaeration of water to create a vacuum in containers, etc. of the above source S. 74 known method quantitative adjustment of the gas-jet apparatus, which consists in reducing the critical section of the nozzle by introducing tapered rod - needle. In liquid-gas units the way of quantitative regulation by type changes in the area of the critical section of the nozzle by typing in the conical section of the rods is not revealed.

A device for humidifying air USSR author's certificate N 387191, CL F 24 F 3/14, 1973, is water-air ejector, representing the number of series-set in the direction of the water jet confusion with the end of the straight sections, and the cross-section of each subsequent downstream movement confuser more of the cross-section of the previous one. Ejecting inside confusion water jet through a circular window between confusioni saturated incoming air, resulting in the dispersed air-water mixture.

Known spray golum the end of the nozzle with the increasing movement of fluid in diameter. The nozzle is made stepwise in the form of a series of cylinders so that the walls of the speed of the cylinder to form an annular chamber. The spray head works on the principle of liquid-gas ejection device with vacuum chambers. Higher efficiency of such a device to obtain a dispersed spray due to the fact that the vacuum chamber promote continuous process of bulk boiling in the gas-saturated liquid, leading to instant destruction of the integrity of the stream and the release of dissolved gases in it.

The disadvantage of this device is the fact that the Central part of ejecting liquid flow due to the large kinetic energy, does not participate in gas destruction, and, therefore, has a low efficiency of spray.

Most gas destruction is exposed peripheral region euchrysea fluid stream in contact with areas of the vacuum.

The technical result achieved by the invention, the efficiency of the spray due to the receipt of thin-dispersed, fully saturated gas volume all the entraining fluid.

This is achieved in that the device for disperse is nutrena surface and the outer surface of the nozzle and the vacuum chamber, according to the invention, it is further provided with profiled rings of increasing diameter and cavitation rod located along the axis of the nozzle with adjustable in the longitudinal direction. Cavitation rod is made with a face area size 0,1-0,35 inner diameter of the nozzle, which is installed on the inner plane of the output section of the nozzle against fluid flow along its axis. On the edge of the nozzle and on the edge of the nozzle is made by machining an acute angle 25-40oand sloping component, that their faces form a vacuum annular zone. Profiled rings of increasing diameter are located along the fluid flow, forming a growing chamber, excluding the manifestation of back pressure by increasing the volume of the liquid-gas phase and increasing the ratio erectionmega gas inside the device.

The invention is illustrated in the drawing, which presents a General view of the dispersing device, which consists of a flange 1, located at the entrance to the confuser 2, nozzle 3, the edge of which, as close as possible to the inner nozzle, the groove 4 having a sharp and flat edges, around which the work is formed vacuum colorology edges, around them in the process, vacuum formed annular area. To increase the volume of the working chamber on the outer edge of the nozzle 5 in the course of the fluid flow are profiled rings of increasing diameter 8. Along the axis of the nozzle 3 has a suction rod, consisting of a working part 9 and the bearing 10, which is the mounting stud. Cavitation rod is made adjustable in the longitudinal direction. Working part 9 of cavitation rod has an end platform, the size of which is between 0.1 and 0.35 inner diameter of the nozzle. The working end space is oriented against the flow of fluid and located on the inner plane of the output section of the nozzle may be adjusted by moving the cavitation rod. Mounting stud 10, which is part of cavitation rod has a bend angle 90oand rigidly mounted on the profiled ring.

The design is going in General candybar shaped ring 8 from the outside are connected by concentric form, for example in three places (on the corner of the 120o) that has almost no influence on the gas dynamics of the ejected into the device flow kazacheskaya destruction of the entraining fluid. At the second stage in the space formed by the profiled rings of increasing diameter, is the uptake dispersed fluid ejected into the device by the gas.

Device for dispersing liquid is as follows.

Ejecting the liquid enters the confuser 2, where increasing its speed of expiration. From confuser 2 the liquid enters the nozzle part 3, where due to the energy of the jet around it occurs spherical vacuum area and, due to the difference in partial pressure of gases in the jet and in empty space, there is a process of bulk boiling gases dissolved in the liquid, resulting in the immediate destruction of the integrity of the jet. When you exit to allow part of the perturbed jet in the Central part meets barrier - face, prohealthcare site cavitation rod 9. Occurs hydrodynamic process called cavitation, which is even more outraged by the stream. Cavitation rod 9 redistributes the Central part of the working fluid at the peripheral area, allowing the entire volume of liquid. The liquid in the zone of the grooves 4 creates a vacuum ring zone, formed by a sharp series of sharp and flat part of the edges of the nozzle 5, complete degradation of the liquid, turning it into thin-dispersed phase. Next is the process of saturation flow thin-dispersed liquid ejected gas through the slotted Windows created profiled rings of increasing diameter 8. Volume of the chamber increases, which compensates for the pressure arising from the increase in bulk density is constantly forming liquid-gas phase. The position of the blunt end of the platform, which may be adjusted by moving the cavitation rod 9, affects hydrodynamic cavitation process, thereby making it possible to adjust the opening angle at the exit of the torch thin-dispersed liquid-gas phase.

The optimal conditions of operation of the device is achieved working pressure of the entraining fluid at the entrance to the confuser - 0.4 to-0.8 MPa.

These factors and ensure the achievement of the technical result.

Device for dispersion liquid containing the confuser, nozzle and fixed on the outer part of the nozzle, forming a vacuum chamber, characterized in that it further provided with a profiled rings of increasing diameter and cavitation rod located PM 0.1 to 0,35 inner diameter of the nozzle, which is placed on the inner plane of the output section of the nozzle against the stream, while on the edge of the nozzle and the nozzle is made by machining an acute angle 25 - 40oC and gentle ingredients that their faces form a vacuum annular zone.
