Super large vertical continuous anaerobic fermentation tank

Abstract

The invention discloses a super large vertical continuous anaerobic fermentation tank which comprises a tank body, a raw material inlet pipe, a pressure protection device, stirring devices, a heat preservation water pipe, a biogas discharge pipe, a biogas residue discharge pipe and a support. The tank body is a sealed steel structure tank comprising a vertical cone top, a circular hollow shell body and a cone bottom. The tank body is divided into four independent feeding and production areas by the four stirring devices, biogas is discharged out by the biogas discharge pipe arranged overhead,biogas residue is discharged out by the biogas residue discharge pipe arranged on the bottom, the tank body is integrally arranged on the ground, and can be thermally insulated by warm water. The beneficial effects are that the amount of raw materials processed per unit time can be increased, intensive production is facilitated, the equipment efficiency can be improved, the continuous and stable production of the biogas can be achieved, and the super large vertical continuous anaerobic fermentation tank can be applied to projects for large scale production of the biogas from biomass.

Description

technical field [0001] The invention relates to the technical field of biological resource recycling, in particular to a super-large vertical continuous anaerobic fermentation tank. Background technique [0002] Compared with the traditional energy market, the commercial competition of bio-natural gas obviously has no advantages. The reasons are as follows: 1. The raw materials of bio-natural gas products are limited, and the raw materials can only be collected within a range of 100 kilometers around the production site. 2. Limited by the biological fermentation process, although the fermentation process conditions are relatively mild, the fermentation time is generally longer. 3. The production capacity of a single set of fermentation equipment is relatively small, which is often not conducive to industrialization and industrialization development. Therefore, the cost of bio-natural gas remains high and the business model is immature. However, from the perspective of envi...

[0002] Compared with the traditional energy market, the commercial competition of bio-natural gas obviously has no advantages. The reasons are as follows: 1. The raw materials of bio-natural gas products are limited, and the raw materials can only be collected within a range of 100 kilometers around the production site

2. Limited by the biological fermentation process, although the fermentation process conditions are relatively mild, the fermentation time is generally longer

3. The production capacity of a single set of fermentation equipment is relatively small, which is often not conducive to the development of industrialization and industrialization

However, from the perspective of environmental protection, the development of biogas with biogas has inherent advantages that cannot be compared with fossil energy: 1. The raw materials of biogas are organic wastes such as livestock and poultry manure, straw and processing waste, etc. If these substances are not fully and effectively use, greatly endangering society
