Problems solved by technology

At present, relevant majors in domestic colleges and universities, such as process equipment and control engineering, face some common problems in the experimental teaching process, the most prominent of which are the slow update of experimental teaching content, the lag in the development of comprehensive experimental platforms, and the establishment of comprehensive, There are very few innovative experiments; the experimental equipment used is a series of experimental equipment with relatively single functions, relatively low integration, and relatively strong independence, such as centrifugal pump performance test benches, liquid flow pattern observation benches, Heater comprehensive heat transfer coefficient test bench, mixer performance test bench, etc.

Although the basic performance experiments of the corresponding process unit equipment can be realized by using these separate experimental equipment, there are the following disadvantages: First, the number of equipment sets required to complete a series of process unit related experiments is large, and the total floor area is relatively large; Second, it is impossible to reproduce the scenarios of complete sets of process equipment that often appear in the above-mentioned different production processes, which is not conducive to the cultivation of students' engineering awareness and system thinking ability; third, it is difficult to set up design, comprehensive and innovative experiments, which is not conducive to students Cultivation of independent thinking and innovative ability

Beijing University of Chemical Technology, Dalian University of Technology, Zhengzhou University, Xi'an Petroleum University, Changchun University of Science and Technology, Wuhan University of Technology and other universities have developed comprehensive experimental platforms suitable for process equipment and control engineering, and these comprehensive experimental platforms can be issued More than 3 types of experiments, but generally speaking, these comprehensive experimental platforms are only a single type of process unit equipment experiment module with expanded functions, and it is difficult to realize joint experiments of more than two unit operations
