APPLICATION OF ENERGY SOURCES OF SUN AND BIOMASS IN FARMING Russian patent published in 2014 - IPC C12M1/02 A01C3/02 

FIELD: power engineering.

SUBSTANCE: invention relates to renewable energy sources to be used in farming. This method comprises application of the Sun renewable energy source and biomass of manure, biogas and slime as organic fertilisers in greenhouses and lawn-and-garden cultures. Firs, during April-October term, greenhouse is heated by water lines heated solely by sun energy to 60…70°C at continuous hot water circulation in closed circuit "greenhouse-reactor-greenhouse" when filtered manure filtrate is fed simultaneously with production of biogas to be discharged via communication pipelines into gas-holder and to household consumers and to boiler room heater. The latter allows circulation of hot water and regulation of constant temperature in said closed circuit "greenhouse-reactor-greenhouse". At a time, bioslime, organic fertilisers, are processed and fed via pipelines into greenhouse and garden-melons-gourds plots. Then, in November-March term two intermediate modes are used. First mode is used when greenhouse is not heated due to recultivation and other works and heated is solely the manure substrate by continuous circulation of hot water in closed water lines circuit "boiler room-reactor-boiler room". Proposed biomass is used like it is at the main mode while biogas is fed to household consumers. The latter allows circulation of hot water and regulation of constant temperature in said closed circuit "greenhouse-reactor-greenhouse". Second mode allows heating of both greenhouse and manure substrate by hot water circulation in closed circuits of "boiler room-reactor-green house" and "boiler room-reactor-boiler room". Processed biogas and bioslime are used similarly to the initial main mode. Then, the latter and two intermediate modes are used again.

EFFECT: application of sun energy for production of biogas and fertilisers, non-polluting organic fertiliser.
