Integrated straw biogas fermentation reactor

Abstract

The invention discloses an integrated straw biogas fermentation reactor that structurally comprises a main body, a skylight, an air outlet pipe and a liquid inlet; the skylight is arranged at the front upper end of the main body; the air outlet pipe is mounted at one end of the main body; the liquid inlet is formed in the other end of the main body; the main body comprises a feeding opening, a discharging bin, a material placing plate and a discharging opening; the feeding opening comprises a liquid inlet pipe, a feeding pipe, a mixing tank, a rotating disc and closing plates; each closing plate comprises a closing body, a mounting groove, a rotating shaft, a connecting rod and a first spring; the closing body comprises a plate body, a groove, a cavity, a second spring, an outer ejector block and a rubber pad; according to the invention, the reactant and the crushed straw are mixed together, so the raw materials impact the closing plates to enable the closing plates to be turned downwards, the raw materials circulate in the feeding port, the first spring resets to drive the connecting rod to be straightened when the raw materials do not circulate, the two closing plates are turnedupwards to be closed together to seal the main body, and air is prevented from entering the main body in the feeding process.

Description

technical field [0001] The invention relates to the field of ventilated solid-phase fermentation equipment, in particular to an integrated straw biogas fermentation reactor. Background technique [0002] In recent years, biomass energy is a green and clean energy that has attracted worldwide attention. The use of straw for biogas production has become an important technical approach for straw disposal and energy conversion. Putting straw in a fermentation reactor for fermentation must be allowed to The reactor is in an anaerobic state, otherwise it will reduce the fermentation speed of straw and reduce the amount of biogas production. [0003] Based on the above inventors’ discovery, the existing integrated straw biogas fermentation reactor mainly has the following disadvantages, for example: after the straw is placed in the reactor for fermentation, it is necessary to open the skylight to put the unfermented straw into the reactor Fermentation is carried out in the reactor...

Problems solved by technology

[0003] Based on the above inventors’ discovery, the existing integrated straw biogas fermentation reactor mainly has the following disadvantages, for example: after the straw is placed in the reactor for fermentation, it is necessary to open the skylight to put the unfermented straw into the reactor Fermentation is carried out in the reactor, so that air will enter the reactor from the skylight, resulting in a large amount of oxygen in the reactor, resulting in a slow fermentation rate of straw in the later stage
