（毕业设计论文）《20万吨造气型煤工艺设计》.doc

摘 要 本文综叙了国内外型煤用粘结剂的研究现状及发展趋势。针对造气行业和冶金行业对型煤粘结荆的要求，本设计采用自制有机-无机复合黏结剂冷压成型工艺，设计规模为20万吨/年造气型煤。生产过程包括制作黏结剂、配料、混捏、压团、干燥、冷却以及三废处理等工序，并对这些工序工艺进行了设计，提出了各工序的工艺流程图。在设计中，以每天产能为依据，对配料、混捏、压团、干燥、冷却等工艺进行物料衡算和热量衡算，为设备选型提供了依据。 根据实验成果制作的有机-无机复合黏结剂，其粘结能力强，材料来源方便，掺量小，成本低，适合于任何煤种。所制型煤的强度高，耐水性好，加工工艺简单，还能固硫减少污染， 在设备选型阶段，对主要设备进行了计算和选型。通过物料衡算、热量衡算及设备选型和车间布置说明，最后得出了设计说明书、设备定型一览表和带控制点的流程图。 关键词：复合黏结剂，造气型煤，冷压成型 Abstract The present situation and the development of the binders in coal briquets were reviewed．Aiming at the gasification industry and metallurgy industries to xingmei binding choic requirement, the design with self-made organic orgamc-inorganic composite binder coldpressing molding process, design size of 20 tons/year type coal gasification. The production process including making adhesives, ingredients, kneading, pressure regiment, drying, cooling and three wastes treatment processes, and these processes are designed and puts forward the process of process flow diagram. In the design, daily capacity as the basis, for the recipe, kneading, pressure regiment, drying, cooling process such as materials calculation and heat balance calculate, provides the basis for the selection of equipment. According to the experimental results make organic orgamc-inorganic composite binder, its binding ability strong, material sources is convenient, the admixture of small, low cost, suitable for any coal. By the system type coal high strength, good water resistance, processing technology is simple, still can solid sulfur reduce pollution, In equipment selection stages, the main equipment is calculated and selection. Through the material calculation, heat calculation and the equipment selection and workshop layout instructions, finally come to finalize the design specification, equipment with control list and flow chart.
