DEVICE OF SUPPORTING GREENHOUSE WITH GASEOUS CARBON DIOXIDE Russian patent published in 2015 - IPC A01G9/18 A01G9/24 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture and equipment for creation in greenhouse complexes for growing vegetables and flowers of optimal concentration of gaseous carbon dioxide at any time of day and year. The device comprises a process pipeline with the reservoir 3 connected to it for long-term storage of carbon dioxide (LSCD), devices for gasification of liquid carbon dioxide in the form of an air evaporator 4 and the system of nozzles 6, a reducer and electric positioner 9 to regulate the pressure of liquid carbon dioxide. The device provides feeding of gaseous carbon dioxide into the greenhouse by transporting the liquid carbon dioxide from LSCD under pressure of 18-22 bar through the electric positioner 9 and further to the gasification device in the form of a system of nozzles 6 from which the gaseous carbon dioxide is supplied to the greenhouse, or by transporting the gaseous carbon dioxide from LSCD under pressure of 10-18 bar through the disconnected electric positioner to the reduction gearbox 7 and then under pressure of 6-8 bar through the disconnected gasification device in the form of a system of nozzles to the greenhouse, or by transporting the liquid carbon dioxide from LSCD under pressure of 18-22 bar on the gasification device in the form of the air evaporator 4, from which the gaseous carbon dioxide is fed through the disconnected electric positioner on the reduction gearbox 7 and further under the pressure of 4-8 bar through the disconnected gasification device in the form of a system of nozzles is fed to the greenhouse.

EFFECT: implementation ensures smooth adjustment of the concentration of gaseous carbon dioxide and brings it to the optimum level for the life of plants, reduction of energy consumption and the cost of agricultural products.
