Abstract

The invention discloses a multistage stirring solar-assisted heating energy-saving fermentation device comprising a fermentation tank composed of an inner-layer tank and an outer-layer tank, wherein the inner-layer tank is a sealed tank composed of a cylindrical tank in the middle, a semispherical tank top and a conical tank bottom, and the semispherical tank top at the inner layer is rotatably connected with a folding rotary tank cover; a three-stage mechanical stirring mechanism is arranged from the semispherical tank top to the bottom of the inner-layer tank; a heat insulation material layer and a multistage constant-temperature heat supply pipe are respectively arranged between the inner-layer tank and the outer-layer tank; a circulating jet-assisted stirring device is arranged in a space formed by the conical tank bottom of the inner-layer tank and the lower part of the outer-layer tank, and is communicated with a biogas circulating mechanism; the bottom of the fermentation tank is provided with a sludge discharging hole, and the side wall of the fermentation tank is respectively provided with a biogas residue liquid discharging hole and a biogas outlet. According to the invention, solar energy and self-sufficient biogas are sufficiently utilized for supplying heat, so that the energy consumption is greatly reduced, the constant-temperature heating is realized, and the multistage stirring solar-assisted heating energy-saving fermentation device is suitable for large-scale popularization and application.

Description

technical field [0001] The invention belongs to the technical field of fermentation equipment, and in particular relates to a multi-stage stirring solar-assisted heating high-efficiency energy-saving fermentation device, in particular to a large-scale biogas engineering anaerobic fermentation treatment device using livestock manure and crop straw as raw materials. Background technique [0002] my country is a large agricultural country with a large population. The amount of agricultural waste resources produced every year is considerable, including a large amount of crop straw, agricultural product waste, poultry and livestock manure, etc. In recent years, as the animal husbandry industry has shifted from scattered farming to intensive and factory-like farming, the feeding methods, breeding scale and distribution area have undergone tremendous changes with the rapid development of my country's economic construction, resulting in the environment of the animal husbandry industr...
