Agitating type biological biogas fermentation tank

Abstract

The invention discloses an agitating type biological biogas fermentation tank which comprises a tank body, a circulation pump, a feed pipe and a discharge pipe; two sets of stirring mechanisms are arranged, each stirring mechanism comprises a rotating shaft, connecting rods, stirring plates and arc-shaped ends, a horizontal vibrating plate is arranged below the stirring mechanisms, a circulating pipe is connected with the circulating pump, the other end of the circulating pipe is connected with a sampling box fixed on the outer wall of the tank body, a booster pump is connected with the bottomof the sampling box, and a plurality of evenly distributed nozzles are connected with a sealing box. The stirring mechanisms are arranged to stir internal liquids thoroughly, and simultaneously the stirring mechanisms rotate to drive the horizontal vibrating plate below the stirring mechanisms to vibrate up and down, so that an internal turbulent flow is formed, the stirring of raw materials is facilitated, and fermentation is thorough; the internal raw materials are circulated under the action of the circulating pump to avoid encrustation on liquid surface, and the fermentation is more thorough.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a stirring biogas fermenter. Background technique [0002] Biogas fermentation, also known as anaerobic digestion and anaerobic fermentation, refers to organic matter (such as human, livestock and poultry manure, straw, weeds, etc.) under certain moisture, temperature and anaerobic conditions, through the catabolism of various microorganisms, and finally The process of forming a flammable mixture of gases (biogas) such as methane and carbon dioxide. [0003] The materials in the biogas fermentation tank will float up during the fermentation process. These floating materials stay on the liquid surface inside the fermentation tank, and after accumulating for a period of time, they will form a layer of thick and hard scum. Traditional biogas fermentation mixing devices mostly use submerged The traditional or horizontal stirring method cannot effectively solve the phenomenon of material cr...

Problems solved by technology

[0003] The materials in the biogas fermentation tank will float up during the fermentation process. These floating materials stay on the liquid surface inside the fermentation tank, and after accumulating for a period of time, they will form a layer of thick and hard scum. Traditional biogas fermentation mixing devices mostly use submerged The traditional or horizontal stirring method cannot effectively solve the phenomenon of material crusting on the top of the fermentation tank, which affects the normal continuous production and operation of the fermentation tank and reduces the biogas output
