Temperature control biomass fermentation tank and fermentation method

Abstract

The invention discloses a temperature control biomass fermentation tank and a fermentation method. The fermentation tank comprises a dry type fermentation tank and a solid-liquid separation device, the dry type fermentation tank comprises a fermentation tank body, a temperature control heating module, a combined type stirrer arranged in the fermentation tank body and a stirring motor driving the combined type stirrer; a feeding hole and a discharging hole are respectively formed in the top and the bottom of the fermentation tank body; the combined stirrer is used for stirring biomass in the fermentation tank body, and the temperature control heating module is used for heating the interior of the fermentation tank body to a set temperature; biomass is added into the fermentation tank body and stirred through the combined type stirrer, the temperature is controlled for dry anaerobic fermentation, then biomass fermentation materials are separated through the solid-liquid separation device, liquid is discharged, and solid fertilizer is reserved. The problems that the fermentation temperature is difficult to control, stirring is uneven, and fermentation materials are difficult to treat are solved, and the fermentation utilization rate is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of microbial fermentation, and relates to a fermentation equipment, in particular to a temperature-controlled biomass fermentation tank and a fermentation method. Background technique [0002] The production of organic fertilizer by microbial aerobic high-temperature fermentation and the production of biogas by anaerobic wet fermentation are the preferred methods for the utilization of livestock and poultry manure and crop straw resources at home and abroad, but these two treatment technologies have shortcomings: nitrogen loss in aerobic high-temperature fermentation technology Large, easy to cause ammonia pollution, at the same time, the fermentation heat cannot be fully utilized, and the fermentation efficiency is low; the anaerobic wet fermentation technology has the problems of digesting biogas slurry and secondary pollution, and the post-treatment procedures of fermentation products are cumbersome. Anae...
