High-concentration continuous dynamic anaerobic fermentation apparatus for multi-element material and application thereof

Abstract

The invention relates to a high-concentration continuous dynamic anaerobic fermentation apparatus for a multi-element material and application thereof. The high-concentration continuous dynamic anaerobic fermentation apparatus comprises a pulp mixing tank and an anaerobic fermentation tank; the pulp mixing tank is an open mixing area; the pulp mixing tank is provided with a biogas slurry filler opening and is equipped with a stirring device; the anaerobic fermentation tank is a closed tank body; the anaerobic fermentation tank is partitioned into a anaerobic fermentation area and a biogas slurry storage area by a partition; the anaerobic fermentation area is positioned above the partition; a feed inlet and a biogas outlet are formed in the top of the anaerobic fermentation tank; a discharge port of the anaerobic fermentation area is formed in the bottom of the anaerobic fermentation area; a discharge propulsion device is assembled at the discharge port; the pulp mixing tank is communicated with the feed inlet of the anaerobic fermentation tank by a conveying pipeline; the material in the pulp mixing tank is conveyed to the anaerobic fermentation area by the conveying pipeline; mutually communicated pipelines are arranged between a biogas slurry outlet of the biogas slurry storage area and the biogas slurry filler opening of the pulp mixing tank. The apparatus is mainly used for high-concentration continuous dynamic anaerobic fermentation of the multi-element material.

Description

technical field [0001] The invention relates to a device for organic waste treatment and renewable energy development and its application, in particular to a high-concentration continuous dynamic anaerobic fermentation device for multiple materials and its application. Background technique [0002] Anaerobic fermentation technology can be divided into wet fermentation and high concentration or dry fermentation according to the dry matter concentration of the fermentation material. The traditional wet fermentation technology is to mix straw with human and animal manure, industrial wastewater and other organic matter, and generate biogas under the action of anaerobic bacteria. Since straw is prone to serious problems such as floating crusting and delamination in wet fermentation, it is mostly avoided to add straw and other substrates with light specific gravity and difficult to degrade. The high-concentration fermentation technology uses solid organic waste as raw material (t...

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the supporting equipment for fermenting high-concentration fermented materials is complicated at present, the process of humidifying and spraying the fermented materials is relatively complicated, the workload of cleaning the materials after each fermentation is large, and the moisture content of biogas residues is high. A series of problems, and after the fermentation of organic materials in high-concentration fermentation devices, the moisture content is generally higher than 75%, and some even reach 85%.
