Abstract

A method for extracting albumin glue from pig dung residues and preparing biomass energy comprises the following steps: 1, cultivating and enriching microbes: introducing the pig dung residues to a collection tank, adding microbe-containing sludge residues, stirring, introducing the stirred pig dung residues and sludge residues to an aerobic tank, and aerating to obtain a sludge-water mixture; 2, continuously hydrolyzing the microbes: adding a self-made modified digestive enzyme, and assisting with microwave digestion to make the microbes be continuously hydrolyzed and be instantly broken in order to form a hydrolysate; 3, carrying out denaturation solidification and extracting the albumin glue: carrying out temperature changing and continuous stirring to make proteins form irreversible gelling, standing to obtain the albumin glue, and dehydrating the hydrolysate to obtain dry dung residues; and 4, molding biomass energy: breaking the dry dung residues, mixing the broken dry dung residues with a powdery biomass raw material, adding the extracted albumin glue, spirally conveying the obtained mixture to a drying system, keeping temperature, humidity and time control, and sending the obtained material to a molding device in order to produce the biomass energy. The method has the advantages of realization of pig dung treatment, recovery of high quality fuel, good quality of the extracted albumin glue, and low cost.

Description

technical field [0001] The invention relates to a technology for extracting protein glue from dung in the breeding industry and preparing biomass energy, in particular to a method for extracting protein glue from pig manure and preparing biomass energy. Background technique [0002] After years of rapid development, the livestock and poultry breeding industry has become an independent industry, but it has also brought about environmental pollution problems that cannot be ignored. The annual discharge of livestock manure in the country has reached 1.884 billion tons, which is equivalent to the annual discharge of industrial waste 3.4 times. More than 80% of the large-scale pig farms in my country have incomplete or not operating normal manure treatment engineering facilities, and some do not even have simple solid-liquid separators. In the design of pig farms that use engineering facilities to treat manure, most of them take environmental protection as the main purpose, an...
