生物质秸秆厌氧发酵生产沼气的工艺
摘要：
本发明公开了一种生物质秸秆厌氧发酵生产沼气的工艺，该工艺的步骤为：（1）用切碎揉搓机将生物质秸秆加工成长度为1.5-2.5cm的柔软丝条；（2）将丝条状的秸秆经输送机送至预处理池，并在预处理池中加入从厌氧反应器回流的沼液，充分搅拌，搅拌后秸秆料液的总固体浓度为20%，然后将秸秆料液在预处理池中堆沤5-7天；（3）将秸秆料液移入装有破壳装置的厌氧反应器中进行发酵，生产沼气，发酵的温度为30-40℃。
摘要（英）：

The invention discloses a technology of producing biogas with biomass straws through anaerobic fermentation. The steps of the technology are: (1) using a chopping and rubbing machine to process the biomass straws into soft filament strips with a length of 1.5 to 2.5 cm; (2) transmitting the straws of soft filament strips into a pretreatment pool through a conveyer, adding the biogas slurry back flowed from an anaerobic reactor into the pretreatment pool, fully stirring, the total solid concentration of the straw material liquid after stirring being 20 percent and retting the straw material liquid in the pretreatment pool for 5 to 7 days; (3) transferring the straw material liquid into the anaerobic reactor installed with a shell-breaking device for fermentation at a temperature of 30 to 40 DEG C to produce biogas.
