Abstract

The present invention discloses a vertical type anaerobic reactor, which mainly comprises a feed port (1), a reactor base plate (2), a reactor cylinder body (3), a tapered flow blocking ring (4), a gas skirt (5), a flow thruster (6), an overflow chute (7), a tapered slag trap (8), a guide shell (9), a guide shell tapered fluid director (10), a base plate tapered fluid director (11), a heating insulating layer (12), a biological gas outlet (13), a discharge port (14) and a sludge outlet (15). The anaerobic reactor can solve the problems of the mixing of scum and sediment and the mixing of broken shell and material system in the anaerobic fermentation process of a high solid material. The gas yield of the high solid material can be improved. The anaerobic reactor has the advantages of energy conservation, high efficiency, easy automatic control implementation and the like.

Description

technical field [0001] The invention relates to main body fermentation equipment in large and medium-sized biogas projects, in particular to a vertical anaerobic reactor. Background technique [0002] Large and medium-sized biogas projects are one of the important means to solve energy and environmental pollution problems, and large and medium-sized biogas projects for livestock and poultry farms account for more than 90% of the total large and medium-sized biogas projects in the country. For the anaerobic digestion technology of livestock and poultry manure and flushing water in livestock and poultry farms, except for a very small amount of dry fermentation technology in China, the rest adopts wet fermentation technology. Since most of the manure of livestock and poultry contains high levels of undigested straw feed and feed additives, more scum and sediment will be produced in the anaerobic digester when the whole manure is fermented. A large amount of scum floats on the ...
