SEAWATER DESALINATION SYSTEM Russian patent published in 2024 - IPC C02F1/02 

FIELD: technology of water and air purification.

SUBSTANCE: invention relates to evaporation devices and can be used for desalination of sea and salt-containing water. System comprises a coarse filtration device, an evaporative circulation circuit of sea water and a condensate circulation circuit of fresh water. Evaporation circulation circuit includes a tank, a heat exchanger for sea water heating, a circulation pump with a capacity control device, device for generation of water vapor, connected in series by pipelines. Reservoir has an air separation hole in the upper part and a hole in the lower part for removal of solid impurities from the flow and brine removal. Condensate circulation circuit of fresh water includes a reservoir, a circulation pump with a capacity control device, device for condensation of water vapor, heat exchanger for recuperation of heat of condensation of water vapor, connected in series by pipelines. Device for generation of water vapor is connected to the device for condensation of water vapor via a pipeline with steam discharge and steam supply tubes. Device for creation of water vapor is made in the form of a pipe with a confuser, having an internal diameter d4, and a cavitator. Device for condensation of water vapor is made in the form of a pipe with a confuser, having an inner diameter d4, and a cavitator. Cavitators are made in the form of a truncated cone with diameters d1 and d3, placed at the end of a steam discharge pipe or a steam supply pipe located inside a pipe with diameter d2. Steam removal and steam supply tubes are combined in the connecting pipeline with the same inner diameter. Ratios of sizes of said diameters are made in intervals: d₄/d₂=2.2–2.4; d₁/d₃=1.4–1.5; d₂/d₁=1.2–1.4. Heat exchanger for heating sea water and the heat exchanger for recuperation of heat of condensation of water vapor are connected to each other by pipelines with the compressor, thus forming a circuit of the heat pump.

EFFECT: higher efficiency.
