The invention discloses a
straight tube type hydraulic type super-effective
methane fermentation device. The
straight tube type hydraulic type super-effective
methane fermentation device comprises a feeding
pipe, a
discharge pipe, a
fermentation pipeline and a
water pressure chamber, wherein the fermentation pipeline is a linear type pipeline, openings are respectively formed in the top parts of the two end sides of the fermentation pipeline and are respectively detachably connected with the feeding
pipe and the
discharge pipe, the side walls of the feeding pipe and the
discharge pipe extend below the liquid level of
biogas slurry in the fermentation pipeline, the
water pressure chamber is mounted at the top part of the fermentation pipeline, a horizontally arranged water drainage pipe of the feeding pipe is connected between the
water pressure chamber and the feeding pipe, and a horizontally arranged water drainage pipe of the discharge pipe is connected between the water pressure chamber and the discharge pipe; a plurality of gas baffles which are arranged between the side walls of the feeding pipe and the discharge pipe are also arranged in the fermentation pipeline, a fermentation region is formed in a space between the side wall of the feeding pipe / the discharge pipe and the adjacent gas baffle or between every two adjacent gas baffles, the top part of each fermentation region is communicated with an independent
airway, and a valve body is arranged on each
airway. According to the
straight tube type hydraulic type super-effective
methane fermentation device disclosed by the invention, the circulation flow stirring performance of the
biogas slurry is strong, strains are promoted to be uniformly distributed by utilizing flow stirring of the
biogas slurry, a fermenting material is also promoted to go deep into a
fermentation system, the fermentation efficiency of the
system is improved, and the gas production of the
system is increased.
