A comprehensive practical training device for the operation of chemical public works

Abstract

The invention relates to an integrated operation practical training device of chemical public work. The device comprises a water supply unit, a heat supply unit, a normal-temperature cooling unit, a low-temperature cooling unit and a vacuum unit; the water supply unit supplies industrial water and process water to the device, and processes steam condensation water generated by the device; the heat supply unit supplies middle-pressure and low-pressure steam to the device, and heats cooling water generated by the device; the normal-temperature cooling unit supplies cooling water to the device; the low-temperature cooling unit supplies low temperature water to the device; and the vacuum unit is sued to generate vacuum negative pressure. Start, stop and load adjustment of all the units as well as the whole practical training device can be carried out, different types of faults can be set so that training students search reasons of the faults according to information including temperature, pressure, flow, valve location and composition and take correct and effective measures to eliminate the faults, a real chemical production scene can be realized. A training scheme which needs autonomous thinking and design can help the students to understand related operations and build up significant engineering viewpoints, and the fault discovery, analysis and elimination capabilities in chemical production can be improved.

Description

technical field [0001] The invention relates to a practical training device for chemical engineering teaching, which is mainly used for teaching training and assessment of post occupational ability of chemical engineering and related professional students and chemical industry operators. Background technique [0002] "Public works" is the general term for all public auxiliary facilities of chemical plants. Although they do not directly process chemical materials, their operating conditions have a great impact on the safe and stable operation of chemical plants, product quality, product costs (levels of material consumption and energy consumption), and economic benefits of enterprises, etc. are crucial. Enterprises have extremely high ability and quality requirements for public works operators. The so-called comprehensive training device for chemical public works operation is to skillfully integrate various water production devices, steam production devices, steam pipe netwo...

AI Technical Summary

Problems solved by technology

At present, the training on the operation of public engineering devices for students is carried out on similar unit operation training devices such as fluid flow, fluid transportation, and heat transfer. During the training process, students can only start and stop operations of simple devices, and verify individual knowledge points in books. , boring, tedious, the training items are simple and rigid, unable to give full play to the subjective initiative of the students; if there is no fault in the device, the students should find out the cause of the fault according to the temperature, pressure, flow, valve position, composition and other information of the device, and use correct and effective methods to eliminate the fault function; In addition, there is a certain difference between the above-mentioned unit operation process and the process carried out in the public engineering device. The device is single and separated from each other, and cannot truly represent the complex and changeable chemical production practice. Adjust the linkage operation training of each device, the training effect is poor, and it is difficult to meet the enterprise's requirements for personnel training
