摘要

随着我国经济的迅速发展,化工业作为重要经济支柱其在国民经济中的地位也越来越高,化工厂也越来越多。在化工生产过程中,基于管线中介质的物理特性、工艺要求以及外部环境等要求,需要对工艺管线或是设备采取一定的保温措施,以保证化工生产的正常运行。我国目前化工生产中针对物料的保温和防冻主要是采取蒸汽伴热和电伴热两种伴热系统。这两种伴热系统在工作原理及需要采取的运行维护措施均有不同,并且基于设备、物料、外部环境及操作人员的不同,选择哪种伴热系统对装置运行及投资成本都会产生较大差异。因此,在化工装置中选择适宜的伴热系统有助于提高项目经济效益。本文主要对蒸汽伴热和电伴热两种伴热系统的工作原理进行分析,并对其在化工工程中的应用进行对比,并指出在化工工程应用中二者的具体差异,给化工从业人员以参考。

Abstract

With the rapid development of my country's economy, the chemical industry, as an important economic pillar, has a higher status in the national economy, and there are more and more chemical plants. In the process of chemical production, based on the physical characteristics of the medium in the pipeline, process requirements and external environment requirements, it is necessary to take certain insulation measures for the process pipeline or equipment to ensure the normal operation of chemical production. At present, the thermal insulation and antifreeze of materials in chemical production in my country mainly adopt two kinds of heat tracing systems: steam tracing and electric tracing. The two types of heat tracing systems are different in working principle and operation and maintenance measures to be taken, and based on the difference in equipment, materials, external environment and operators, which heat tracing system to choose will have a greater impact on the operation and investment costs of the device. difference. Therefore, choosing a suitable heat tracing system in a chemical plant will help to improve the economic benefits of the project. This paper mainly analyzes the working principles of two heat tracing systems, steam tracing and electric tracing, and compares their applications in chemical engineering. And pointed out the specific differences between the two in the application of chemical engineering, for the reference of chemical practitioners.

Key words: Electric heat tracing system; Steam tracing system; Application; Chemical plant
