FIELD: fire-extinguishing; transport; heat and power industry; devices for the liquids atomization. ^ SUBSTANCE: the invention is pertaining to the devices for the liquids atomization and may be used in the fire-extinguishing installations, in the composition of the processing equipment for the fuel burning in the heat and power engineering and in transport. The invention solves the problem to increase efficiency of the fire-extinguishing process at usage of the finely dispersed water with the fire-extinguishing additives due to formation of the plume with the uniform dripping structure and the optimal speed of the liquid delivery at the simultaneous decrease of the hydraulic losses, and also at the simplified serviceability. The device contains the body of the sparger supplied with the liner and conjugated by means of the threaded coupling with the distribution chamber, in which the strainer basket is mounted. The liner contains the swirling chamber supplied with the holes and the cylindrical tailpiece with the tangential holes. Coaxially with the liner there is the mounted spray jet, the internal surface of which is made in the form of the conical contraction, and the external surface is made in the form of the conical diffuser. In the central part of the spray jet there is the hole. At that the liner and the spray jet are fixed in the body by the stop member, and the distribution chamber has the offtake, in which the strainer basket is arranged. At that thus the butt of the offtake is supplied with the plug. Usage of the indicated device allows to generate the finely dispersive drip streams of the thin atomization with minimal power inputs at the water saving rate. The device has the small overall dimensions and the streamline form. It is possible to use the water with the additives including the water penetrating agent or the surface-active substance. ^ EFFECT: the invention ensures the increased efficiency of the fire-extinguishing process, formation of the plume with the uniform dripping structure, generation of the finely dispersive drip streams of the thin atomization with minimal power inputs at the water saving rate and the optimal speed of the liquid delivery, the decreased hydraulic losses, the simplified serviceability. ^ 3 cl, 1 dwg |
