Embodiment Construction
[0016] Such as Figure 1~4 As shown, a comprehensive self-assembly experimental device for tube and tube heat exchange includes a water tank 1, a water heater 12 and a tube and tube heat exchanger 7. The water tank 1 and the cold medium inlet of the tube and tube heat exchanger 7 are connected through a cold water pipe 6. The cold medium outlet of the tube heat exchanger 7 is connected to the water tank through the cold water return pipe 11; the water outlet end of the water heater is connected to the heat medium inlet of the tube heat exchanger 7 through the hot water pipe 8; The hot water return pipe 9 connected to the water end, the other end of the hot water return pipe 9 is connected with two hot water return branch pipes 10 respectively leading to the two ends of the tube water heater 7, the heat medium outlet of the tube water heater 7 is connected to the two hot water return pipes One of the branch pipes 10 is connected. The cold water in the heat exchanger goes throug...

The invention relates to a comprehensive self-assembly experimental device and an experimental method for tubular heat exchange. The device comprises a water tank, a water heater, a tubular heat exchanger and a hot water return pipe. The water tank is communicated with a cold medium inlet of the tubular heat exchanger through a cold water pipe, a cold medium outlet of the tubular heat exchanger is communicated with the water tank through a cold water return pipe, and a water outlet end of the water heater is communicated with a hot medium inlet of the tubular heat exchanger through a hot water pipe. One end of the hot water return pipe is connected with a water inlet end of the water heater, the other end of the hot water return pipe is connected with two hot water return branch pipes which are connected to two ends of the tubular heat exchanger respectively, and a hot medium outlet of the tubular heat exchanger is communicated with one of the two hot water return branch pipes. The comprehensive self-assembly experimental device for tubular heat exchange is convenient to use, quick assembly and disassembly can be realized, and students can carry out experiments of heat exchangers different in tube pass through the experimental device and can demount and mount seal plugs to change tube pass numbers; comprehension of theoretical knowledge can be enhanced through comparison of various data.
Description
technical field [0001] The invention relates to a tube and tube heat exchange comprehensive self-assembly experimental device and an experimental method thereof. Background technique [0002] Chemical engineering principle experiment is a professional basic compulsory course for chemical engineering and near chemical related majors, which belongs to the category of engineering experiment and has obvious engineering characteristics. Each experimental project is equivalent to a unit operation in chemical production. Certain engineering concepts can be established through experiments, and heat transfer experiments are one of the important links in the teaching of this course. However, the previous experiments were all carried out on fixed equipment, and the content of the test was less and not comprehensive enough. The influence of students on the number of tube passes and heat exchange area was only theoretical, and the installation, operation, and The ability to debug and ot...
