Title:
NON-POWERED STIRRING ORGANIC WASTE ANAEROBIC FERMENTATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/161232
Kind Code:
A1
Abstract:
The invention provides a non-powered stirring organic waste anaerobic fermentation device. By arranging a T-shaped spacer, an internal chamber of an anaerobic fermentation device is divided into an upper chamber and a lower chamber. The amount of biogas generated therein is different because of a certain volume difference between the upper and lower chambers. A pressure difference between the biogas in the upper and lower chambers causes a height difference of the slurry in the upper and lower chambers. By opening and closing a pipeline valve, pressure of the biogas can be released or increased, so that the slurry in the upper and lower chambers repeatedly flows back and forth to enhance the mixing and stirring of the slurry.
