毕 业 设 计 题目 日投1500张黄牛皮轻革（包袋革）工厂设计 日投1500张黄牛皮轻革(包袋革)工厂设计 摘 要 本文以日投1500张黄牛包袋革的制革厂为设计内容，生产所用的黄牛皮主要来源于中原地区的黄牛皮，品种选择品质较好的晋西牛皮。包袋革的生产工序包括准备工段，鞣制工段和整饰工段。本设计根据晋西黄牛皮的特性及包袋革的要求，在遵循高效率、高质量、易操作、绿色生态的原则下，以提高资源利用效率、减少污染和增加企业利润为主要目标。在设计中立足国产设备，适当引进。在工艺中收集用于洗灰皮的水进行浸灰等一系列环保、节水、节能措施。同时基于制革业对环境的污染严重，采用集中生产，集中治理的生产模式，并在制革生产过程中使用无氨氮脱灰技术，循环利用灰液，碱沉淀法回收铬。本设计的另一个重点是污水处理及工厂的平面布置，污水处理部分，从污水来源、污水分析及污水处理工艺三个方面进行了阐述，工厂平面布置则是严格按照符合实际生产要求，考虑生产流程、厂区高效利用、管理方便的要求来进行布局的，包括工厂总平面布置和生产车间布置。 关键词：黄牛皮，包袋革，工厂设计，工艺方案，三废治理 The Design of Leather (Bag Leather) Factory With Produce 1500 Pieces of cow Hide Daily ABSTRACT The design is based on the tannery with daily output of 1500 cow bag leather, raw hide can be obtained from the Central Plains region and we select the cow from west of Shanxi province for it good quality. Production processes contain beamhouse, tanning process, finishing process. According to property of cow hide from the west of Shanxi and the demand of bag leather and following some basic principles, such as high efficiency、high quality、easy-to-use、green chemistry, the design is aim at rising utilization efficiency of resources, decreasing the pollution and increasing business profit. Bases the home equipment in the design, suitable introduction. Collected in the process used to wash the gray skin of water liming and a series of environmental protection, water conservation, energy-saving measures. While tanning industry based pollution of the environment seriously, centralized production, centralized management mode of production. And used in the tanning process without the production of ammonia from the ash technology, recycling gray liquid, alkaline precipitation recovery of chromium. The other most important part of this paper is sewage treatment, and layout of the factory. For sewage treatment, the design was elaborated in three aspects, source of water contamination, and analysis of sewage and wastewater treatment process. Layout of the factory is strictly in acc
