【摘要】：我国是一个农业大国,生物质资源非常丰富,农作物秸秆资源量6-8亿吨。由于农作物秸秆传统功能的消失和农业生产的季节性特点,焚烧、抛沟河己成为当前农民处理秸秆的快捷手段,由此产生了大气和水环境污染,影响交通、危害人身健康和财产安全,有效利用农作物秸秆已经成为当务之急。秸秆属于低碳燃料,硫含量均低于煤炭,是一种“清洁绿色可再生能源”。我国高度重视再生能源的使用,提出减少化石能源使用比例,大力发展低碳经济,鼓励秸秆发电,并出台了一系列优惠政策。据调查,生物质发电厂普遍存在本地黄色秸秆收集难的问题,经常舍近求远,需赴外地采购灰色秸秆,造成能源的浪费,另一方面农村稻麦秸秆无法运离田头,农民付之一炬,导致空气污染。如何解决秸秆转运的问题,是保护生态环境、改善能源结构的关键。农作物秸秆转运成本直接关系生物质发电的效益,如果处置不当,就会直接影响生物质电厂的储存运行。分布式秸秆转运系统由秸秆的收集、由转运站初步加工处理、储存、运输成品至生物质发电厂几个环节。本文以射阳县国能射阳生物发电有限公司为样本,用层次分析法和问卷调查的方法证明秸秆发电是秸秆综合利用的最佳方法之一,并指出秸秆物流是保证秸秆发电厂正常运营的重要环节；对秸秆转运系统进行分析论述,按分布式秸秆二级转运体系运行秸秆收储运,可解决秸秆物流的困难。分布式秸秆转运系统是一个特殊的物流系统,本文作者重点考察国能射阳生物发电有限公司物流系统运作中存在的问题,通过建立最优秸秆转运系统的目标数学模型,结合线性规划和经济学最小成本法,分析研究秸秆转运系统的布局和数量规模设置,寻求物流中心的科学选址方法和解决秸秆收储运成本高的途经。
[Abstract]:China is a large agricultural country, rich in biomass resources, crop straw resources 6-800 million tons. Because of the disappearance of the traditional function of crop straw and the seasonal characteristics of agricultural production, burning and throwing ditch river have become the quick means for farmers to deal with the straw, which has resulted in air and water pollution and affected traffic. Endangering personal health and property safety, the effective use of crop straw has become an urgent matter. Straw is a low-carbon fuel, sulfur content is lower than coal, is a "clean green renewable energy." China attaches great importance to the use of renewable energy, proposes to reduce the proportion of fossil energy use, vigorously develop low-carbon economy, encourage straw power generation, and issued a series of preferential policies. According to the investigation, the problem of local yellow straw collection is common in biomass power plants. They often go to other places to buy gray straw, which results in waste of energy. On the other hand, the rural rice and wheat straw cannot be transported away from the field, and the farmers are burned to the fire. Cause air pollution. How to solve the problem of straw transportation is the key to protect ecological environment and improve energy structure. The transportation cost of crop straw is directly related to the benefit of biomass power generation. If the disposal is not proper, it will directly affect the storage and operation of biomass power plant. The distributed straw transportation system is collected by straw, processed, stored and transported to biomass power plant by transfer station. This paper takes Sheyang Guoneng Sheyang Biogeneration Co., Ltd. as a sample, and proves that straw power generation is one of the best methods for comprehensive utilization of straw by means of analytic hierarchy process (AHP) and questionnaire survey. It is pointed out that straw logistics is an important link to ensure the normal operation of straw power plant, and the difficulty of straw logistics can be solved by analyzing and discussing the straw transportation system. The distributed straw transportation system is a special logistics system. The author focuses on the problems in the operation of the logistics system of Guoneng Sheyang Bio-electric Power Co., Ltd., and establishes the objective mathematical model of the optimal straw transportation system. Combined with linear programming and economic minimum cost method, the layout and quantity scale of straw transportation system are analyzed and studied, and the scientific location method of logistics center and the way to solve the high cost of straw collection and transportation are sought.
