Abstract
A large-type horizontal device and a method for continuous methane fermentation. The whole distribution of a fermentation compartment uses a U-shape plane layout, which is a snap-back type and uses a material propeller. The material propeller has two axes and two blades and is constantly occluded with counter rotation. The irreversible propulsion of materials can be realized through counter rotation of two occluded blades. The propeller is set at the bottom of the main partition of the fermentation compartment. The propel ability of propeller can be changed through changing of rotation speed. Counter rotation of two occluded blades can realize material propeller without material reverting. The inlet and outlet entrances of the reactor in the disclosure are near to the ground and can be operated conveniently. The homogeneous output of materials and entire plug-flow can be realized at the same time without material mixing in the whole process.
