Abstract

1. Способ тушения пожаров газожидкостной смесью, заключающийся в том, что возбуждают ультразвуковое поле и воздействуют им на истекающий поток газожидкостной смеси, отличающийся тем, что истекающую газожидкостную смесь формируют в виде разделенных друг от друга порций жидкости и газа, а частоту колебаний генерируемого ультразвукового поля задают близкой к частоте, с которой истекают порции жидкости и газа газожидкостной смеси.2. Газожидкостная форсунка, содержащая корпус с полостью переменного сечения и выпускными отверстиями, отличающаяся тем, что полость образована двумя соосными полыми цилиндрами разного диаметра с торцевыми поверхностями, при этом в торцевой поверхности большего цилиндра выполнены осевые выпускные отверстия, а в боковой поверхности малого цилиндра - радиальные отверстия так, что между торцевой стенкой малого цилиндра и плоскостью сечения, в которой расположены радиальные отверстия, образована полость.3. Форсунка по п.2, отличающаяся тем, что осевые и радиальные выпускные отверстия выполнены парными, причем оси каждой пары отверстий и ось форсунки лежат в одной плоскости.1. The method of extinguishing fires with a gas-liquid mixture, which consists in the fact that they excite an ultrasonic field and act on the outflowing stream of the gas-liquid mixture, characterized in that the outflowing gas-liquid mixture is formed in the form of separated portions of liquid and gas, and the oscillation frequency of the generated ultrasonic field set close to the frequency with which portions of the liquid and gas of the gas-liquid mixture expire. 2. A gas-liquid nozzle comprising a housing with a cavity of variable cross-section and outlet openings, characterized in that the cavity is formed by two coaxial hollow cylinders of different diameters with end surfaces, with axial outlet openings in the end surface of the larger cylinder and radial openings in the side surface of the small cylinder so that a cavity is formed between the end wall of the small cylinder and the section plane in which the radial holes are located. 3. The nozzle according to claim 2, characterized in that the axial and radial outlet openings are paired, the axes of each pair of holes and the axis of the nozzle lying in the same plane.
