METHOD OF PRODUCTION OF BIOGAS FROM AGRICULTURAL WASTE AND BIOGAS PLANT FOR ITS IMPLEMENTATION Russian patent published in 2012 - IPC A01C3/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of processing of organic waste of livestock, crop husbandry and food industry. The method of production of biogas from agricultural waste includes the preliminary waste homogenisation, the subsequent separation of waste for components, supply of biodegradable waste components to the container of biogas production, and subsequent separation or joint use of components and biogas. Preliminary waste homogenisation is performed regularly in a closed space with supply in equal portions for separation, in the process of waste separation for components a part of liquid fraction is removed by gravity flow for self-use, and before supply of biodegradable waste components in the container of biogas production the solid organic substance is added in their composition and an enzyme mass is formed of them. The mass is supplied to the container of biogas production. Before the separation a portion of waste is separated into two unequal parts, the biggest of which is sent for separation, and the smallest is sent directly to the container of biogas production.

EFFECT: invention enables to improve the performance of biogas complex and uniformity of mode of its operation in conditions of significant change in climate and the characteristics of the feedstock, with simultaneous ensuring the reliability of operation of container of biogas production in conditions of significant drop of temperature of the environment.
