将虚拟装配技术引入化工流程中,对可视化设计化工流程、培训工人操作技能以及化工厂的数字化建设具有很大的应用价值。通过分析精馏系统,搭建了可视化装配平台。根据装配约束条件建立了可装配设备模型。提出了"1+1"和"1+n"普遍化的装配方法,实现了装配复杂精馏系统。通过输出装配信息,获取精馏系统装配过程中的装配方式和装配序列,验证装配操作的正确性。装配测试表明装配方法正确可行,其真实性、准确性和有效性满足了精馏系统虚拟装配的要求,实现了自由选择设备装配所需的精馏系统。系统可扩展性强,通过添加其它单元设备,可以实现所有化工流程的虚拟装配。

Virtual assembly technology, which was introduced inthechemical process, has great valueon the visual design of chemical processes, training workers in skills, as well as digital construction of chemical plants. By analyzing the distillation system, a visual platform was established. According to the assembly constraints, the model of equipment can be assembled was constructed. The ＂1＋1＂ and ＂l＋n＂ universality assembly method was proposed, and assembly of a complex distillation system was realized. According to the output assembly information to get the assembly mode and sequence in the assembly process of the distillation system, correctness of the assembly operation can be verified. Assembly tests proved that the assembly method works well in operation efficiency, and its validity, accuracy and effectiveness meet requirements of virtual assembly of distillation system, choosing devices freely to assembly required distillation system was realized. The sealability of the system is strong, virtual assembly of all chemical processes can be achieved by adding other unit equipment,
