毕业设计说明书 年产20万吨硫酸生产车间工艺设计 年产20万吨硫酸生产车间工艺设计 摘 要 硫酸是最重要的基础化工原料之一，主要用于制造磷肥及无机化工原料，其次作为化工原料广泛应用于有色金属的冶炼、石油炼制和石油化工、橡胶工业以及农药、医药、印染、皮革、钢铁工业的酸洗等。本设计以硫磺为原料生产硫酸，因为以硫磺为原料生产硫酸不需净化，大大简化了工艺过程，节省投资费用，且产品质量高。 本设计完成了年产20万吨硫酸生产车间工艺设计，介绍了硫酸生产的主要方法和成熟的工艺流程。主要内容包括原料熔硫工段、焚硫转化工段、干吸工段及主要设备的选择、环保措施等。完成了化工设计的各个设计环节，达到了设计目标。经分析，设计技术可靠，经济合理。在设计过程中，还重点对废水处理进行了分析。 关键词：硫酸；硫磺制酸；焚烧炉；转化塔 The Production Process Design of the Workshop for Sulfuric acid with an Annual Output of 200,000 Tons Abstract Sulfuric acid is one of the most important basic chemical raw materials, mainly used in the manufacture of phosphate fertilizer and inorganic chemical raw materials, as a chemical raw material, it is widely used in non-ferrous metal smelting, petroleum refining and petroleum chemical industry, rubber industry, as well as pesticides, pharmaceuticals, printing and dyeing, leather pickling of iron and steel industry. This design is used sulfuric acid as raw material to product sulfur, thus it products sulfur without purification, the process is greatly simplified to save investment costs and gain high product quality. It is an annual output of 200,000 tons of sulfuric acid production plant process design, introduces the main methods of sulfuric acid production and mature process. The main contents include the raw material sulfur melting section, and burning sulfur conversion section, drying and absorption section and the major equipments selection, environmental protection measures. It completes various links of the chemical engineering design, and achieves the design objectives. Through the analysis of the design, design technology is reliable, and the design is economical and reasonable. In the design process, it is also focusing on wastewater treatment.
