METHOD AND INSTALLATION OF FIRE WATER SUPPLY FOR ARID REGIONS Russian patent published in 2019 - IPC A62C35/00 B01D53/26 F25B25/00 

FIELD: water supply.

SUBSTANCE: invention relates to water supply, in particular to methods for production or collection of drinking or tap water, as well as to firefighting equipment, and can be used for fire extinguishing in arid regions, with scarcity of water sources. Method of fire water supply for arid regions, including collection and storage of water in pressure and control reservoir, water supply to points of consumption along pipelines system with required pressure by means of high pressure pumping station, provision of permanent fire-prevention volume of water in pressure-control capacity due to separation of suction pipes of household-drinking and fire pumps and removal of suction pipe of industrial-household pumps to level of untouched fire-prevention volume. Water is condensed from atmospheric air with the help of water extractor operating from renewable energy sources, extracted water is directed by inclined pipeline by gravity to pressure-regulating tanks, thus filling reservoirs, and excess is directed to household needs, and moisture extraction is carried out round the clock. Installation for implementation of fire water supply method for arid regions comprises pressure and control tank for collection and storage of water, system of pipelines for supplying water to a point of consumption, a high-pressure pumping station with separate suction pipes of fire and household-drinking pumps, wherein the suction pipe of the household-drinking pump is at the level of untouchable fire-prevention capacity. Claimed plant is equipped with water extractor from atmospheric air with wind turbine operating from renewable energy source, wherein the water extractor is connected to the water collection and storage vessel by the inclined pipeline, through which the water produced in the extractor flows by gravity into the pressure-control vessel, wherein the water extractor is located above the level of the water container.

EFFECT: task of the proposed invention is to ensure fire-prevention water supply by taking water from an autonomous self-filling water reservoir operating from renewable energy sources (RES), for areas with an arid climate with shortage of water resources, as well as partial water supply for household needs.
