Abstract[English]
The present invention is directed to a system (100) for anaerobic dry digestion of lignocellulosic biomass comprising: a dry digester (110) comprising a ground sheet (111) and a cover (112) for the lignocellulosic biomass. The digester (110) generates leachate and biogas from anaerobic digestion. The system includes an irrigation/port system (113) for wetting of the lignocellulosic biomass under the cover (112); a sump system (120) for monitoring the leachate; a rotary valve (130) connected at least to the pump (126) and the dry digester (110); a gas storage bladder (140) for collecting the biogas, the gas storage bladder (140) connected at least to a gas treatment unit (150) and a gas booster pump (160); and a hi-rate digester tank (170) connected at least to the rotary valve (130) for receiving the leachate therefrom.[French]
La présente invention concerne un système (100) de digestion sèche anaérobie de biomasse lignocellulosique comprenant : un digesteur sec (110) comprenant une feuille de sol (111) et un couvercle (112) pour la biomasse lignocellulosique. Le digesteur (110) génère un lixiviat et un biogaz à partir d'une digestion anaérobie. Le système comprend un système d'irrigation/port (113) pour mouiller la biomasse lignocellulosique sous le couvercle (112) ; un système de puisard (120) pour surveiller le lixiviat ; une vanne rotative (130) reliée au moins à la pompe (126) et au digesteur sec (110) ; une vessie de stockage de gaz (140) pour collecter le biogaz, la vessie de stockage de gaz (140) étant reliée au moins à une unité de traitement de gaz (150) et à une pompe de surpression de gaz (160) ; et un réservoir de digesteur à haut débit (170) relié au moins à la vanne rotative (130) pour recevoir le lixiviat à partir de celle-ci.
