Biogas production and separation device

Abstract

The invention discloses a biogas production and separation device which comprises a feeding box, a plurality of fermentation boxes, a delivering box and a separation box, a discharging port of the feeding box is selectively and sequentially communicated with feeding ports of the plurality of fermentation boxes through a first switch assembly, discharging ports of the plurality of fermentation boxes are sequentially communicated with a feeding port of the delivering box through a second switch assembly, and a first discharging port of the delivering box is communicated with a feeding port of the separation box through a third switch assembly; a first push plate is movably arranged in the separation box, the first push plate can push biogas residues in the separation box out of the separation box into the delivering box and is communicated with a second discharge port of the delivering box through a fourth switch assembly.

Description

technical field [0001] The invention relates to a biogas production device, in particular to a biogas production and separation device. Background technique [0002] Biogas is produced by the decomposition of organic substances by a variety of microorganisms (collectively referred to as biogas bacteria) under the conditions of isolating the air and maintaining a certain moisture, temperature, and pH. The process in which biogas bacteria decompose organic matter to produce biogas is called biogas fermentation. This is the basic principle of biogas generation, that is, the anaerobic mechanism. Biogas is a mixed gas whose main component is methane, followed by carbon dioxide, hydrogen sulfide (H2S), nitrogen and other components. In the composition of biogas, combustible components include gases such as methane, hydrogen sulfide, carbon monoxide and heavy hydrocarbons; non-combustible components include gases such as carbon dioxide, nitrogen and ammonia. In the biogas composi...

Problems solved by technology

[0005] The existing biogas digesters have a simple structure and cannot separate the water and biogas residues in the pond, resulting in more and more dilution of the fermented product and lower fermentation efficiency, which affects the production and utilization efficiency of biogas. Manual feeding and drainage for separation, the efficiency of separation is low, and the workload is heavy, and biogas will be absorbed during the operation process. Biogas will produce harmful substances that are harmful to the human body. Personnel need to avoid excessive inhalation of biogas, biogas Slag and biogas slurry pollute the environment and need to be recycled reasonably
