Abstract

The invention discloses horizontal push-flow continuous dry fermentation equipment and method, and relates to the technical field of material fermentation. The equipment comprises a fermentation equipment body, a material inlet is arranged in the top of the front end of the fermentation equipment body, and a material outlet is arranged in the bottom of the rear end of the fermentation equipment body; the outer wall of the fermentation equipment body is provided with a heat preservation device, the interior of the fermentation equipment body is provided with a stirring device, the stirring device includes a stirring shaft and stirrers, the stirring shaft is arranged in parallel at the middle of the fermentation equipment body, the stirring shaft is connected with a driving device, and the stirring shaft is provided with a plurality of stirrers; the fermentation equipment body includes a plurality of detachably connected fermentation equipment modules, and the plurality of fermentation equipment modules communicate in sequence; and the tops of the fermentation equipment modules are connected with a biogas tube. According to the equipment, materials can be uniformly mixed, mass and heat transfer in the fermentation equipment can be reinforced, the stability and efficiency of an anaerobic digestion system can be improved, and the equipment adopts the modular splicing structure, thereby being convenient for assembly, replacement, manufacturing, maintenance and repair.

Description

technical field [0001] The invention relates to the technical field of material fermentation, in particular to a cross-flow type continuous dry fermentation device and method. Background technique [0002] The output of agricultural waste in my country is huge, with 900 million tons of crop straw and 3.8 billion tons of livestock and poultry manure collected each year, which not only poses a potential threat to the living environment, but also contains a large amount of resource potential. Using anaerobic fermentation to treat waste with high organic content such as livestock and poultry manure and crop straw can not only promote the harmless and reduced treatment of organic waste, but also realize resource utilization and energy utilization, and produce clean energy. Promote the improvement of energy structure, improve the living environment in rural areas, and ultimately achieve sustainable economic and social development in rural areas. [0003] At present, the anaerobic...

Problems solved by technology

However, these devices are mainly used to deal with urban domestic waste. For the large amount of organic waste such as livestock and poultry manure and crop straws produced in my country, their adaptability is poor, and due to the poor fluidity of materials with high solid content, vertical push Flow-type continuous dry fermentation equipment is difficult to manufacture and install. When the material has a high solid content, it is prone to problems such as difficulty in feeding and discharging materials, short service life of feeding and discharging equipment, and poor operation stability; horizontal continuous dry fermentation devices usually use central The way of shaft screw conveying, the monomer volume is small, the stirring is uneven, the mass transfer is difficult, and the microbial habitat environment is prone to imbalance
