FIELD: agriculture and municipal economy.
SUBSTANCE: the is intended for use in municipal economy and in agriculture for a sequential phase-by-phase anaerobic fermentation of different solid non-graded and non-ground fermentable organic waste materials of cities and settlements, waste products of agricultural enterprises, agricultural farms, bungalows and households with production out of them of the high-quality decontaminated from a pathogenic microflora, helminths, their eggs and seeds of weeds, liquid mineralized organic fertilizers with a good share of humus and a combustible biogas used for the power purposes. The methane-tank contains a horizontal basin separated by internal alternately not reaching up to the top and the bottom of the basin cross partitions for the gas sections with the gas collectors and the liquid flowing through communicating chambers with draw-off taps, a loading and an unloading connecting pipes, heaters of fermentable mass and a gas pipeline of a gasholder linked to the gas collectors of gas sections. The basin has a built-in chain-scraper type loading-unloading elevator with a drive, which horizontally located one over another working branches with a perforated fence between them and around of them are inserted from the direction of a loading connecting pipe inside the basin below the level of the fermentable liquid organic mass set in the basin. The gas collector of the first gas section is connected with a gas pipeline of drawing the biogas off from the section into an injector interacting with a discharge pump pumping out of a fermentable mass of the chamber and boosting it back into the chamber through a connected with it injector and a disperser of the gas-liquid mixture formed in the injector. The technical result: improvement of the methane-tank design, provision of an efficient splitting of the solid fermentable organic substances of the waste products and the greatest output of the high-quality liquid mineralized saturated with humus organic fertilizers and a combustible biogas of high calorific value.
EFFECT: the invention ensures upgrade of the methane-tank design and the greatest output of the high-quality liquid mineralized saturated with humus organic fertilizers and a combustible biogas of high calorific value.
