Abstract

The invention discloses a rheid fermenting cellar and a method for producing methane by utilizing the rheid fermenting cellar. The rheid fermenting cellar comprises a seal housing (1) and cement floor (5), the seal housing (1) is made from flexible sealing membrane material and the lower edge of the seal housing (1) is a ring-shaped air inflation sealing ring (2).The cement floor (5) is embedded with a ring-shaped groove (3), the cross section of the groove is in the shape of an inverted ohm shape with the small opening and the large cavity. The air inflation sealing ring (2) is integrated with the ring-shaped groove (3) and tightly integrates the seal housing (1) and the cement floor (5) after being aerated, thus forming a sealed rheid fermenting cellar. The top of the rheid fermenting cellar is provided with a methane outlet pipe (4).In the invention, the solid state fermentation technology is adopted, the pretreated ferment raw material is charged in a split mode in plastic boxes( barrels) suitable for transportation, and piled up and stacked in advance in the rheid fermenting cellar. The method of the invention has large production of methane, simple device structure, easy construction, small investment and low cost.

Description

Technical field

[0001] The invention relates to a method for producing biogas, in particular to a soft fermentation chamber, a method for producing biogas in a large-scale manner, and belongs to the technical field of biomass energy and environmental protection. Background technique

[0002] my country's biogas production technology is at a leading level in the world, and the scale of biogas development ranks among the top in the world. Especially in rural household biogas digester technology, there have been many national standards. However, this technology is limited to one household and is not suitable for large-scale biogas production.

[0003] In recent years, large and medium-sized biogas projects have continued to emerge, the technology has become increasingly mature, and the supporting equipment has approached the international level, but most of the projects are for environmental protection purposes, especially large-scale livestock and poultry farms that have built the m...
