SCALABLE BIODIGESTER PLANT FOR GENERATING BIOGAS FROM LIVESTOCK PURINES

摘要

The invention relates to a scalable biodigester plant for generating biogas from livestock liquid manure, comprising a concentration tank (2) with a stirrer (3) associated with a pretreatment tank (5) and treatment tanks (6) by means of a liquid manure pipe (4), with a heating pipe (7) communicating said tanks (5, 6) with a heater/generator (8), a biogas pipe (9) communicating the tanks (5, 6) with the heater/generator (8), and a discharge pipe (10) communicating the tanks (5, 6) with the solid/liquid separator (11), the tanks (5, 6) being movable and consisting of 20' or 40' maritime transport containers open in the upper part, and an expandable rubber dome (12) that seals said upper part allowing only the passage of the biogas pipe (9), the containers being covered internally with a thermally insulating layer (13) that is, in turn, covered with a reinforcement layer (14).
