Integrated livestock and poultry cultivation system of biomass combined heat and power generation

Abstract

The invention relates to the technical field of cultivation and comprehensive utilization of resources, and specifically relates to an integrated livestock and poultry cultivation system of biomass combined heat and power generation. The cultivation system comprises a cultivation room; a heating device, a cooling device, a flushing device, an illumination device and a feces collection tank are arranged in the cultivation room; and the system also comprises a feces regulation tank, a sewage sedimentation tank, a first biogas fermentation tank, a second biogas fermentation tank, a methane extraction device, a methanol solution synthesis device, a biogas liquid and biogas residue treatment device, a reformer of hydrogen production by using methanol water, a fuel cell and a control device. According to the invention, heat energy and electric energy are generated through the conversion of livestock and poultry cultivation wastes, and the intelligent control of the whole system is realized,so that the biomass energy source can be efficiently converted and comprehensively utilized, the ecological integrated livestock and poultry cultivation system can be formed, and the system has a wideindustrial application prospect.

Description

technical field [0001] The invention relates to the technical field of breeding and comprehensive utilization of resources, in particular to an integrated livestock and poultry breeding system for combined heat and power generation of biomass. Background technique [0002] Environmental pollution and energy shortage are two major themes worldwide, and it is imminent to develop technologies for green environmental governance and renewable energy production. According to statistics, my country's large-scale livestock and poultry farming produces about 3.8 billion tons of livestock and poultry farming waste (feces) every year. If it is completely converted into biogas, it is equivalent to 162 million tons of standard coal, and only about 15% of which are equipped with biogas projects. Handle equipment. Livestock and poultry manure has become one of the main sources of agricultural non-point source pollution. A large amount of livestock and poultry manure has been discharged wit...

Problems solved by technology

However, the existing methods for treating manure in the process of livestock and poultry breeding have the following main problems: (1) The manure of livestock and poultry is not fully utilized and transformed well, the treatment method of manure of livestock and poultry is single, there is no comprehensive treatment, and the treatment efficiency is low , and the equipment occupies a large area, and the operation and maintenance costs are high, which affects the large-scale promotion and use; (2) The storage, transportation and effective utilization of biogas prepared from livestock and poultry manure have always troubled people

On the one hand, biogas contains toxic gases such as hy...
