摘要:

全世界温室气体很大部分来自畜禽的饲养和粪便等,联合国粮食及农业组织FAO的调查报告指出,畜牧业是所有产业中对温室效应“贡献”最大的产业。在当前“碳达峰、碳中和”目标背景下,针对规模化养猪场造成的能源浪费和环境污染问题,构建以清洁能源为主的养猪场多能互补系统,具有节能减排、提高能效水平的重要意义。结合多能互补与能源梯级利用的思想,根据养猪场自身条件,考虑到养猪场具备丰富的生物质能和太阳能,且日常用电量大,冬季热负荷高,构建了养猪场多能互补系统结构。基于某养猪场实际的规模概况和负荷需求选择合适的配套设备,基于PVsyst软件进行光伏发电的模拟计算。综合考虑系统的投资成本、设备运维成本、电热负荷需求、季节性需求,最终计算得到养猪场在行业基准收益率为8%的基础上仍可收益158.57万元,动态投资回收期约为7.3年,与传统养猪场从电网购电相比,每年可减少二氧化碳排放量204.29 t,表明该系统能为养猪场带来良好的经济效益,且具有显著的节能减排和绿色环保优势,能够为养鸡场、养牛场等其他养殖场提供新的经营思路。

Abstract:

A large part of the world’s greenhouse gases comes from livestock and poultry breeding and manure. A survey report by the Food and Agriculture Organization of the United Nations (FAO) pointed out that animal husbandry is the industry that contributes the most to the greenhouse effect among all industries. Against the backdrop of the current goal of achieving “carbon peak and carbon neutrality”, in order to address the energy waste and environmental pollution caused by large-scale pig farms, building a multi energy complementary system for pig farms with clean energy as the main focus is of great significance in energy conservation, emission reduction, and improving energy efficiency. Inthelight of multi-energy complementation and energy cascade utilization, a multi-energy complementary system in pig farm has been constructed based on the pig farm’s own conditions that the pig farm has abundant biomass energy and solar energy, and it also has large daily electricity consumption and high heat load in winter. Based on the scale overview and load demand of the pig farm, appropriate supporting equipment was selected, the simulation calculation of photovoltaic power generation was conducted using PVsyst software. Taking into account the investment cost, equipment operation and maintenance cost, electric heating load demand, and seasonal demand of the system. Taking into account the system investment cost, equipment operation and maintenance cost, electric heating load demand, and seasonal demand, the final calculation showed that the pig farm can still earn 1.585 7 million yuan based on the industry benchmark return rate of 8%, and the dynamic investment recovery period is approximately 7.3 years. Compared with traditional pig farms purchasing electricity from the grid, it can reduce carbon dioxide emissions by 204.29 tons per year, indicating that the system can bring good economic benefits to pig farms and has significant energy-saving, emission reduction, and green environmental protection advantages. It can provide new business ideas for other farms such as chicken farms and cattle farms.
