Problems solved by technology

[0003] Since chemical raw materials and products are mostly toxic and harmful substances, and production is usually carried out under high temperature and high pressure, it is difficult to ensure safety and environmental protection in the teaching and training room
Therefore, it is difficult for the production device to be transplanted into the teaching and training room
In the teaching, it can only be displayed or simulated in the form of a process flow chart. Students only see the general shape of the equipment and the direction of the main materials, but cannot see the whole picture of the production device and the realization of production. Even if they go to the enterprise for training, they can only see it. , cannot be operated, it is difficult for students to understand the realization of the entire production process from raw materials to products, which affects students' understanding of the production process, perception and cultivation of production and operation skills. Enterprises achieve "zero distance" docking, which cannot meet the requirements of enterprises

Abstract

The invention relates to a simulation teaching factory for preparing cyclohexane through benzene hydrogenation, which comprises a chemical engineering device construction area, an indoor operating area and a teaching discussion area, wherein a miniature chemical engineering device, a device frame and the like are arranged inside the chemical engineering device construction area; a control system is arranged inside the indoor operating area and is communicated with the miniature chemical engineering device through a signal cable; and the teaching discussion area is provided with computers and multimedia teaching facilities which are connected with the control system through a signal cable inside the indoor operating area. The simulation teaching factory is basically consistent with actual conditions of a factory, the structure and general situation of a real chemical production device can be realistically known, the cognition of chemical engineering equipment is improved, the actual operating level is enhanced, and cooperation capacity and team spirit are cultivated. Students can really know the structure and general situation of the chemical production device controlled by a decentralized control system (DCS) and can accept chemical production DCS operation training, and the capacity of analyzing and solving problems also can be cultivated and improved.

Description

technical field [0001] The present invention relates to a simulation teaching factory in the field of chemical engineering, in particular to a simulation teaching factory for hydrogenation of benzene to cyclohexane, which belongs to the technical fields of education, chemical technology and equipment, and is used for various colleges and universities in chemical engineering and The integration of theory and practice teaching and professional practice of related majors, as well as the training of chemical technicians and senior technicians. Background technique [0002] In order to achieve the goal of cultivating professional talents in chemical technology in higher vocational education, the "teaching-learning-doing integration" teaching mode has become an inevitable requirement of today's higher vocational education. The most effective way is to "transplant" typical chemical production equipment to teaching practice. [0003] Since chemical raw materials and products are mo...
