Abstract

Principles of chemical engineering course is designed to serve as a bridge between theory and practice, is to observe the complexity of engineering practical problems early attempts. Through the principles of chemical engineering course design, the integrated use of basic knowledge of the principles of chemical engineering course, basic principle and basic calculation, to achieve mastery through a comprehensive, independent thinking, within the prescribed time to complete the design tasks designated by the chemical unit operations, has the ability of the preliminary engineering design; To familiar with the basic content of engineering design, grasps the chemical single yuan operation design of the main procedures and methods; To improve and further develop our ability to analyze and solve practical problems. This design as the kettle surface residue is agent of preliminary design, is a shell and tube heat exchanger, clock can be cooling to the appropriate temperature, the residual liquid from the hot kettle residual liquid tube side, the shell side of the coolant walk. With the development of chemical industry and the increase in the price of energy, heat exchanger occupies very important position in the chemical production. Shell and tube heat exchanger is a heat transfer area is large, the advantages of compact structure, tighten the heat transfer effect is good, can use a variety of materials, low prices. Based on previous production as a design of data and calculation, to determine the specific type. Assembly drawing with AutoCAD drawing layout, the main configuration and take back the control points of process flow diagram, finally complete the design specification.

Keywords: kettle residual liquid; Cooler; The preliminary design
