Предлагается способ пожаротушения с применением вихревых водных огнетушителей: вихревого водного циклонного огнетушителя и вихревого водного смесителя-огнетушителя, работающих на основе вихревого эффекта конфузора. Способ заключается в поглощении вихревым водным огнетушителем одновременно с вихревой водной переработкой в огнетушителе пламени, дыма, частиц окружающей среды и последующем направлении образовавшейся аэрозольной огнетушащей смеси на тушение пламени. Это позволяет сдерживать увеличение площади пожара, а также эффективнее использовать водные ресурсы при его тушении. Приводятся преимущества новых вихревых водных огнетушителей перед огнетушителями других типов.

The article proposes a new method of fire extinguishing with the use of new vortex water fire extinguishers using a new physical process “vortex confusor effect”: a vortex water cyclone fire extinguisher and a vortex water mixer - fire extinguisher. The method consists in the absorption of flame, smoke, and environmental particles by a vortex water fire extinguisher, simultaneously with the vortex water processing in the fire extinguisher of the absorbed flame, smoke, and environmental particles, followed by the direction of the formed aerosol extinguishing mixture to extinguish the fire, which allows to restrain the increase in the area, volume of the fire, and also to use water resources more efficiently during fire extinguishing. The essence of the “vortex confusor effect” is the formation of a new swirling flow in the opposite direction of movement to the originally swirling flow. The physical process of the “vortex effect of the confuser” is described directly, a description of the schematic diagram of the “counter vortex” formation is given, the advantages of which are provided by the use of the “vortex effect of the confuser”. New vortex water fire extinguishers are proposed, which allow for a new method of fire extinguishing. The first part of the article describes the well-known air-foam ejecting trunks that allow crushing the water flow into aerosol particles. There is given a description of the new device - a vortex water cyclone fire extinguisher, a description of its basic scheme of operation, as well as the advantages of vortex water fire extinguishing devices. The formation of a counter vortex in the process of the “vortex effect of the confuser” is given in the description of the schematic diagram of the implementation of the physical process “vortex effect of the confuser”. A fire extinguishing mixture can be formed using another new fire-fighting device - a vortex water fire extinguisher. The article describes a schematic diagram of the functioning of a vortex water fire extinguisher. In the actual design and subsequent manufacture of vortex water fire extinguishing devices, it is necessary to ensure safe and convenient distances for the mutual arrangement of flame suction modules; a module for mixing flame components with an injected water jet; a module for forming a fire extinguishing mixture into an aerosol jet of the desired consistency and shape. The real water pressure, the design of interconnected overpasses for continuous water supply of vortex fire extinguishing devices, the implementation of technological fire extinguishing processes, the physical process of the “vortex confuser effect” itself ensure the fulfillment of these requirements. The use of the proposed devices in unmanned fire extinguishing devices, both automated, mobile, and stationary, carriage, multi-barrel, seems promising. The physical process - the “vortex effect of the confuser” - will be one of the main ones in an unmanned automatic fire extinguishing device. The implementation of the method consists in the manufacture of the proposed technological schemes for the functioning of vortex water fire extinguishers with subsequent use in the workflow. The new ones are directly vortex water and vortex cyclone fire extinguishers. But, vortex water and cyclone fire extinguishers as equipment are structurally simple, there are no moving parts in them, as such, the devices are technologically advanced in manufacturing. It is possible to produce them in each mechanical workshop.
