Title:
BIOGAS SLURRY, BIOGAS RESIDUE AND BIOGAS PRODUCTION TANK FOR GRASS PLANTING IN ALPINE PASTURING AREA
Document Type and Number:
WIPO Patent Application WO/2023/138326
Kind Code:
A1
Abstract:
Disclosed in the present invention is a biogas slurry, biogas residue and biogas production tank for grass planting in an alpine pasturing area. The tank comprises a biogas digester body, outer-layer glass fiber reinforced plastic, a heat insulation film, a heat insulation medium and a carbon fiber heating cable. The heat insulation film is arranged outside the biogas digester body, the heat insulation medium is arranged outside the heat insulation film, the outside of the heat insulation medium is covered by the outer-layer glass fiber reinforced plastic, and an inner side of the heat insulation film is connected to the carbon fiber heating cable by means of bonding. By means of the biogas slurry, biogas residue and biogas production tank for grass planting in an alpine pasturing area, a heating structure and a heat insulation medium are added, such that a biogas digester body is heated and heat is prevented from being externally transferred, the problems in a traditional biogas digester of a fermentation temperature not reaching the standard, the fermentation of biogas slurry and biogas residues being poor, the quality of a fertilizer being poor and the biogas production efficiency being low when the traditional biogas digester is used in an alpine pasturing area are solved, and in this way, the fermentation temperature inside the biogas digester is increased, such that the fermentation temperature inside the biogas digester is at an appropriate temperature level, the fermentation effect is good, and the practicability is high.
