Horizontal type anaerobic reactor

Abstract

The invention discloses a horizontal anaerobic reactor which consists of a feed hole (1), a reactor main body (2), a gas collection chamber (3), a dreg settling zone (4), a dreg collection hopper (6) and an overflow groove (7). The reactor is characterized in that the reactor main body (2) has a cylindrical tubular structure, the rectangular gas collection chamber (3) is arranged at the top of the reactor main body (2), a biological fuel gas outlet (9) is arranged above the gas collection chamber (3), the semicircular dreg settling zone (4) is arranged at the bottom of the reactor main body (2), the feed hole (1) is arranged at one end of the reactor main body (2), the overflow groove (7) is arranged at the other end of the reactor main body (2), a discharge hole (11) is arranged on the overflow groove (7), the end of the dreg settling zone (4) is connected with the dreg collection hopper (6), and a sludge outlet (12) is arranged under the dreg collection hopper (6). The reactor can solve the problems of mixing of dreg floating and settled dregs and mixing cracking system and material system in the course of the anaerobic fermentation of high solid materials, and is characterized by energy saving, high efficiency and automatic control.

Description

technical field [0001] The invention relates to main body fermentation equipment in large and medium-sized biogas projects, in particular to a horizontal 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 th...
