Emulation teaching plant for continuous DOP production

Abstract

The invention discloses an emulation teaching plant for continuous DOP production, which comprises chemical equipment, an equipment frame and chemical instruments, wherein the chemical equipment is arranged on the equipment frame and the chemical instruments are connected with corresponding chemical equipments. The emulation teaching plant for continuous DOP production is characterized in that: the chemical equipment comprises esterification equipment, dealcoholization equipment, neutralizing and washing equipment, gas stripping equipment and absorption and filtration equipment, wherein the esterification equipment, the dealcoholization equipment, the neutralizing and washing equipment, the gas stripping equipment and the absorption and filtration equipment are connected in sequence and the equipment frame is provided with an upper layer and a lower layer. The structure design of the emulation teaching plant for the continuous DOP production is basically consistent with the practical condition of the plant equipment, and in the process of using the emulation teaching plant for teaching, students can really get an idea of the structure and general situation of rear chemical production devices, so the knowledge of the students of various chemical equipment is enriched, the practical operation level of the students is improved and the collaboration abilities and team spirits of the students are developed.

[0002] Situational teaching has always been one of the main teaching methods in colleges and universities. With the continuous deepening of teaching reform, the teaching scene has also undergone major changes, especially the in-depth promotion of the integrated teaching mode of theory and practice carried out nationwide. Higher requirements have been put forward for the teaching scene, and various colleges and universities have also done a lot of work for this. At present, the main scenes of chemical engineering major teaching are roughly as follows: The first is a completely real chemical device, which is generally The original school-run factory was closed down due to various reasons, and it was directly used for teaching. Students can familiarize themselves with the chemical production process on this device, and they can also conduct simulated production drills. However, the device occupies a large area and it is impossible to use it When it is moved to the classroom, it is difficult to carry out integrated teaching of theory and reality, and the device cannot feed materials, everything is in a static state, students do not have the feeling of chemical production and operation, and cannot achieve the desired effect; the second is a completely virtual chemical Device, without any physical objects, everything is carried out on the computer. At present, most colleges and universities use this device. This device does not have any physical input except the computer, and the operating cost is relatively small. Students attend classes in the computer room, in front of the computer, Follow the operation steps to imitate DCS and device on-site operation. This kind of training can enable students to have a more intuitive understanding of DCS and device on-site operation. However, due to the lack of real objects, it is more like playing a software game; the third It is to build a chemical device in a relatively large classroom. The device generally scales down the production process device of a certain chemical product to make a device model, and then uses simulation software to implement DCS control on the device. What needs to be done On-site operation depends on the additional signal of the valve to be transmitted to the computer. Through this kind of training, students can have a sense of reality when performing DCS and device on-site operations, and are closer to the real state of chemical production. The operating cost is also very small, but because the device is a scaled-down version of the original real device, there is a lack of coordination among the various devices as a whole, and some devices are even smaller than the pipeline, making it difficult for students to feel that it is a chemical device. In addition, the frame of the device is mostly made of decorative materials, which greatly reduces the realism of the chemical device. Furthermore, the simulation software has basically not changed much, and it cannot be the same as the real chemical production. Several operating stations jointly operate a device. There is no on-site detection instrument, only the same transmitter, which is far from the real chemical plant
