Thermal insulation biogas fermentation tank

Abstract

The invention relates to the technical field of biogas fermentation devices, and is a thermal insulation biogas fermentation tank; it includes an inner tank, an outer tank, a feeding device, an exhaust device, an overflow device, a discharge device, an insulating layer and a stirring device; the inner tank It is fixed together with the outer tank, and a heat insulation cavity is formed between the inner tank and the outer tank, and an insulation layer is installed in the heat insulation cavity, and the upper part of the outer tank and the inner tank is fixedly installed with a feeding material communicating with the inner cavity of the inner tank. fittings, exhaust fittings and overflow fittings. The invention has a reasonable and compact structure and is easy to use. By installing a thermal insulation layer in the thermal insulation chamber, the thermal insulation effect is good, and the heat generated in the fermentation process can be fully utilized to achieve the temperature required for subsequent fermentation. Through the adjustment of the temperature control device, the The temperature inside the fermenter is always at the optimal fermentation temperature, so as to ensure that the adiabatic and heat-retaining biogas fermenter is not affected by the seasons, so it not only improves the biogas production rate, but also reduces energy consumption and saves costs.

Description

technical field [0001] The invention relates to the technical field of biogas fermentation devices, and relates to an adiabatic and thermal insulation biogas fermentation tank. Background technique [0002] At present, a kind of known biogas fermentation container is a brick fermentation tank, a kind of large and medium-sized metal fermenter, and a small chemical material fermenter. These fermentation containers are equipped with several parts such as stirring device, heating system, circulating waterway, loading and unloading device, and exhaust system. The fermentation raw material enters the main tank through the feeding device, after adding water, it is mixed evenly by the stirring device, and the fermentation starts. The generated biogas is discharged from the exhaust system, and the biogas residue is discharged from the unloading device. However, the fermentation of biogas requires a certain fermentation temperature (about 49.5°C) to have the maximum yield. The thickn...
