FIELD: fire-prevention engineering and agriculture; methods of production of gas-drop highly concentrated jets with a long range of action. ^ SUBSTANCE: the invention. The offered invention is dealt with technologies of production of highly concentrated jets having a long range of action and finely dispersive structure of drops. Such jets may be used in fire-prevention engineering and agriculture for sprinkling and in fields of economy, where there is a necessity in the finely dispersed long range gas-drop jets. The offered group of inventions solves the following problems: provision of formation of a gas-drops two-phase stream by a method permitting to increase an overall performance of the device due to more rationalized use of energy of a liquid and a guaranteed method of dispersion of a two-phase bubbling gas-liquid stream. This technical purpose in the offered invention is achieved by development of a method of formation of a gas-drop jet providing for feeding of a liquid and a gas stream, dispersion of the liquid, mixing of the dispersed liquid with the gas stream and a speed-up of the produced two-phase gas-drop jet, in which according to the invention, a liquid is fed along the axis of the gas-drop jet. At that the liquid is dispersed a stage by stage and a gas stream, and a liquid disperse stage by a stage, preliminary they create a two-phase stream of a bubbling structure by feeding a part of the gas in the liquid. Then this mixture is subjected to action of cavitation or shockwaves and then the dispersed liquid is mixed with the rest of the gas. The invention is also characterized by the fact, that the gas-drop jet is placed in an additional external gas coaxial stream of the same direction. ^ EFFECT: the invention ensures provision of formation of a gas-drops two-phase stream by a method permitting to increase an overall performance of the device. ^ 4 cl, 2 dwg |
