Purpose of the development: The device for supplying finely atomized water extinguishing substances is intended for the formation and supply of finely dispersed water (TRV) into the volumes of the premises during a fire extinguishing; it works together with a portable fire extinguisher.

Recommended application field: Fire and rescue units of the State Emergency Situations of Ukraine.

The development stage readiness: Pre-production model is made

Description of the development:
()
The device consists of a spray nozzle (full cone), a pipeline, a ball valve, a pressure gauge, a water filter, a connecting head, and a special attachment to a smoke exhauster. The principle of operation of the device for supplying expansion valves and a portable fire smoke absorber consists in their simultaneous operation in order to receive and supply an air-water jet. An air-water stream is obtained as a result of 2 components: water and air. A device is used to obtain finely dispersed water, and a portable fire smoke exhauster is used to obtain an air stream. From a fire truck through pressure fire hoses with a diameter of 38 mm connected to the connecting head of the device, water through a water filter, a remote pressure gauge along an open tap, flows through a pipeline into nozzles, where it is sprayed and supplied with a stream of air from a working smoke exhauster to the room where the fire occurs. A prototype device for supplying a finely sprayed jet of water was introduced in the fire and rescue unit of the Children's Socialist Council of Ukraine in the Lviv region.
