BIOENERGY COMPLEX FOR PRODUCTION OF BIOGAS AND GRANULAR BIOFUEL

摘要

FIELD: oil and gas industry.;SUBSTANCE: invention relates to the field of biogas production using the method of anaerobic methane fermentation. The bioenergy complex for production of biogas and granular biofuel is offered. The complex includes a biopond and the unit for production of gaseous biofuel, with the series-connected branch pipes for biomass supply by chipper, homogenizer and bioreactor. The bioreactor consists of, at least, one methane tank, the gas output of which through gas-holder and compressor is connected with the power unit. The tanks made from composite elastomers with polyurethane or polyvinylchloride two-sided coating are used as pressure-tight methane tanks that are equipped with the piping heating system. The tanks are connected through branch pipes with the hydromixing system. The chipper has a receiving bin, and the output for the used bioreactor biomass is provisioned with the receiving vessel. The complex is supplemented with the unit for pellet fabrication, with the possibility of its work in a mode of fabrication of pellets from green vegetative mass, planted in the biopond, or in the mode of fabrication of pellets from biomass processed in the reactor. The unit for fabrication of pellets consists of the pressing-out unit, and the liquid discharge branch pipe of the pressing-out unit is connected with the possibility of adjustment with the homogenizer of the unit for production of gaseous biofuel or with the biopond. The solid fraction output of the pressing-out unit is connected with granulator, the output of which is connected with the packaging line for two kinds of pellets.;EFFECT: invention allows to perform deep degassing of organic mass, to increase the output of biogas, profitability of biogas units for electrical power generation in a low power range from 10 kW/h up to 500 kW/h, expand functionalities, ensure mobility and work capacity of the complex in any climatic conditions.;9 cl, 2 dwg
