AGRICULTURAL COMPLEX FOR PRODUCING MICROALGAE USING GEOTHERMAL SOURCES Russian patent published in 2022 - IPC A01G33/00 F03G7/04 E04H5/08 

FIELD: agriculture.

SUBSTANCE: invention relates to an agro-industrial complex. Agricultural complex for producing microalgae using geothermal sources comprises a structure consisting of two blocks, an administrative block and an industrial block including a storage tank for emergency water supply to open reactors and to the greenhouse, as well as laboratories for conducting research of microalgae. Open-type reactors for growing microalgae are located at different levels downslope from each of the laboratories, wherein straight-cycle geothermal power plant tanks using dry steam to generate electricity are located under said reactors. Through the filters, dry steam rises to rotate a turbine therein, supplied directly from the geothermal well, having passed through a condenser and a cooling tower intended for cooling the circulating water used to remove heat from the process equipment in circulating water supply systems. The condensate is returned to the tank by means of an injection well, and microalgae are heated in open reactors, wherein one part of the grown biomass is directed as cattle feed to the cattle shed, and the other part is supplied to silos as a reserve. Organic fertiliser is created as a result of enzymatic and microbiological processing by the body of cattle, wherein part of said fertiliser is returned to the reactors to create a nutrient medium.

EFFECT: autonomous and waste-free agricultural production of microalgae based on geothermal energy.
