METHOD OF FORMATION OF THE GAS-DRIPPING SPRAY AND THE DEVICE FOR ITS REALIZATION Russian patent published in 2007 - IPC B05B7/04 

FIELD: fire-extinguishing;; methods and devices of formation of the gas-dripping spray.

SUBSTANCE: the group of inventions is pertaining to the methods and the devices of formation of the gas-dripping spray used for fire-extinguishing, and may be used at fire extinction of the peatland fires, forest fires, fires in the high-rise buildings, etc. The group of the inventions ensures improvement of the thermodynamic cycle of the fire-extinguishing installation using the gas-turbine engine, the increase of the installation operation economy and efficiency of the fire-extinguishing due to substitution of the air containing the oxidizing agent (oxygen) and used for formation of the gas-dripping spray for the combustion products, which practically do not contain the oxidizer. The method provides for feeding of the liquid and the gaseous working medium created by the gas-turbine engine, dispersion of the liquid, commixing of the dispersed liquid with the gaseous working medium and the speedup of the produced two-phase gas-dripping stream. As the gaseous working medium use the partially waste products of the gas-turbine engine combustion taken out between the turbine stages, which is cooled before its commixing with dispersed liquid in a heat-exchanger, and the liquid heated in the heat-exchanger is routed into the combustion chamber. The installation for realization of the method contains the mounting frame, the gas-turbine engine consisting of the compressor, the combustion chamber and the gas-turbine having at least two stages and the outlet nozzle, the gas-turbine engine fuel system, the fuel tank, the mechanically linked with the turbine engine electrogenerating device and water pumps of the high, mean and low pressure, the collecting tank for the liquid, the linked with it water-intake device made in the form of the reception hose connected to the low-pressure pump, the turning fire-fighting nosepiece, the drive gear of its turning movement, the control system, which is linked with the drive gear of the turning fire-fighting nosepiece and with the electrogenerating device, the pipe ducts, the chamber of commixing of the liquid and the gaseous working medium of the turning fire-fighting nosepiece and with the inlet of the liquid feeding and having the inlets of feeding of the gaseous working medium, the foam-producing device connected by the pipe duct with unit of the gaseous working medium feeding into the unit of commixing of the liquid and the gaseous working medium of the fire-fighting nosepiece. At that the installation is supplied with at least one outlet of the working medium made between the stages of the gas-turbine and connected at least with one heat-exchanger and the device of refrigeration of the gaseous working medium, with which the installation is supplied.

EFFECT: the group of inventions ensures improvement of the thermodynamic cycle of the fire-extinguishing installation using the gas-turbine engine, the increased economy and efficiency of the installation fire-extinguishing operation.
