Abstract


Energy is the driving force of economic development , is the material basis of modern civilization . Energy savings , the rational utilization significant . Some of the early completion of the chemical companies , the technical backwardness , unreasonable design of heat exchanger networks , resulting in a waste of energy . With the development of technology , the transformation of the original heat exchanger network optimization has become an effective means of these enterprises to reduce production costs and increase economic efficiency . Pinch Technology was first proposed by Professor Linnhoff It thermodynamic principles and systems engineering combined to determine the optimal configuration of energy utilization and recycling of process systems . To grips transformation heat exchanger network , concise , intuitive, energy-saving effect , has been widely used in the production practice . In the process of implementation of the optimization of heat exchanger networks using pinch technology , along with a large number of mathematical calculations . In the rapid development of computer technology , this cumbersome process can use the computer to simplify . Demand for heat exchanger network transformation of Shanghai Chlor-Alkali Chemical Co., Ltd. , designs, develops a heat exchanger network-assisted optimization system . This paper analyzes the characteristics of the Microsoft Visio software in the development of language and development platform , according to the functional requirements of the system's heat exchanger network optimization , the final choice to Visio as a development platform and with embedded VBA language development . Visio as a platform to play Visio advantage of the powerful graphics capabilities , and enhance the performance of the products , and eliminating the need for the development of the system graphics engine parts , simplifies the development process . The article discusses the heat exchanger network optimization system in Visio based on the advantages and feasibility of secondary development of the overall system design and development process , and to achieve the basic functions of the system . At the same time , but also to solve some technical problems Visio secondary development process . Completion of the heat exchanger network optimization system has the following functions : to draw heat exchanger network flow chart to generate heat exchanger network diagram , calculate the heat exchanger network pinch point , generate heat exchanger network temperature - enthalpy diagram analysis and optimization of heat exchanger network . The system and compared to similar products have a visual , interactive , easy to operate features . The heat exchanger network transformation of the system will greatly simplify the process of heat exchanger network transformation , improve work efficiency .
