S-shaped channel type anaerobic fermentation device

Abstract

The invention relates to an S-shaped channel type anaerobic fermentation device relating to a fermentation device. The S-shaped channel type anaerobic fermentation device comprises a feeding pond, an anaerobic fermentation pond and a discharging pond, wherein the feeding pond and the discharging pond are positioned at one side of the anaerobic fermentation pond; the upper ends of the feeding pond and the discharging pond are higher than the anaerobic fermentation pond; the top end of the anaerobic fermentation pond is sealed; and the anaerobic fermentation pond is internally provided with a plurality of partition plates or partition walls for structuring one or more groups of S-shaped channels. Fluid substances are sufficiently subjected to anaerobic fermentation by flowing in the anaerobic fermentation pond in an ponds-shaped channel way and then discharged from an overflow opening of the discharging pond, and methane generated through the anaerobic fermentation in the anaerobic fermentation pond is discharged through a gas guide hole arranged on the top end, enters a gas storage hood and is discharged and collected along a gas guide pipeline positioned at the top end of the gas storage hood. The invention has simple structure, very convenient construction and time and material saving, can be used for large and medium methane engineering construction, lengthens the anaerobic fermentation process through S-shaped channel type arrangement and greatly promotes the flowability of the substances through a capacious S-shaped space, thereby enhancing the gas generation efficiency; and in addition, the invention has convenient later-stage maintenance and management and simple and easy normal discharging and large discharging, and is suitable for being popularized in large quantities in rural areas.

Description

technical field [0001] The invention relates to a fermentation device, in particular to an S-shaped channel type anaerobic fermentation device. Background technique [0002] At present, microbial fermentation is an effective way to obtain a large number of microbial products. Since some microorganisms are obligate or facultatively anaerobic, anaerobic fermentation devices are required. The current situation of existing anaerobic fermentation equipment is: small-scale cultivation relies on the method of anaerobic tanks or small-volume reaction bottles, and large-volume fermentation requires special fermentation equipment. In our widely used biogas fermentation collection device, it is a large-scale fermentation equipment. At the same time, in order to better obtain biogas and increase the effect of anaerobic fermentation, we need to modify the anaerobic fermentation device.

Problems solved by technology

[0003] In the anaerobic fermentation devices currently used in rural areas for the characteristics of straw materials, it is difficult to achieve a "continuous flow" reaction during the fermentation process due to the low density, large volume, and lack of fluidity of the straw. Anaerobic, it is necessary to solve the problem of fluidization of straw and the maintenance of a large number of anaerobic bacteria in a fluidized state
