Abstract

The patent of the invention discloses a fermentation device for enhancing electron transfer in anaerobic fermentation, and specifically relates to the technical field of anaerobic fermentation devices. Including a fermenter, the inner wall of the fermenter is provided with an insulating interlayer, the center of the top of the fermenter is provided with a drive motor, the drive motor is provided with a rotating shaft connected to the bottom of the fermenter, and the rotating shaft is equidistant along the long axis. One electric stirring assembly, each electric stirring assembly is composed of a stainless steel plate and a biochar plate coated in the stainless steel plate, the surface of the biochar plate is evenly distributed with a number of hemispherical concave cavities, the stainless steel plate and the motor are connected with a battery group; the upper top of the fermentation tank is provided with a feed inlet, the bottom side wall of the fermentation tank is connected with a discharge outlet, and the inlet and outlet are equipped with switching valves. The technical solution of the invention can solve the problem of poor material conversion efficiency caused by low electron transfer efficiency in the anaerobic fermentation process, and can be used in anaerobic fermentation projects of agricultural waste such as crop straws, livestock and poultry manure.

Description

technical field [0001] The invention relates to the technical field of anaerobic fermentation devices, in particular to a fermentation device for enhancing electron transfer in anaerobic fermentation. Background technique [0002] Every year, a large amount of agricultural waste is produced in our country, such as crop straw, livestock and poultry manure, etc. Because it cannot be recycled in a timely, reasonable and effective manner, it is often discarded in the field or directly ignited and burned. There are "three lows and one heavy" problems of low utilization rate, low conversion rate, low economic benefit, and serious environmental pollution. At the same time, it has also caused serious environmental pollution and huge waste of resources. Only the efficient and comprehensive utilization of agricultural waste can effectively solve the above problems, which plays an important role in the sustainable development of modern agriculture. Among them, anaerobic fermentation ...
