AUTONOMOUS SOLAR BIOGAS PLANT Russian patent published in 2020 - IPC C02F11/04 C12M1/107 F24S20/00 

FIELD: power engineering.

SUBSTANCE: invention relates to bioenergetics and can be used for production of biogas and ready organic products by biochemical treatment of organic wastes. Autonomous solar biogas plant includes a reactor placed in a reservoir with liquid, in which around the reactor there are containers with a phase-transfer thermal accumulator, charged with thermal energy of solar collectors. Installation contains a reservoir for preparation of the initial raw material substrate, a faecal pump, a gas holder, a reservoir of liquid fertilizer, solar collectors, a circulating pump, a thermocontrol with thermal sensors and servo drives. Apparatus is configured to heat the substrate dose fed daily into the reactor to the fermentation temperature by switching the circulation of heat carrier heated by the solar collectors through a heat exchanger installed in the reservoir for preparing the raw material substrate.

EFFECT: technical result consists in maintenance of optimal temperature mode for fermentation of biomass in reactor, as well as in heating daily dose fed into reactor.
