Simulation teaching device and system of antioxidant production device

Abstract

The invention relates to a simulation teaching device and system of an antioxidant production device, which takes a process for producing an antioxidant through alkylation of p-phenylenediamine as a prototype, and comprises a cold-state driving simulation module, a normal parking simulation module and a common accident handling operation module. The system is further provided with an evaluation system module and a teacher station management system module, and the functions of the modules are achieved by operating simulation flow chart pictures displayed on a computer. The 'simulation version' is installed in a computer and does not communicate with a production device, and trainees can complete training operation of cold-state driving, normal parking and common accident handling of the antioxidant technology on the computer; the 'practical operation version' is installed in a control room computer, is connected with a DCS through an OPC interface technology and is further in data communication with a field device. The system can be used for simulation teaching and can also be applied to management operation of real chemical production, students can conveniently master post operation skills and know real production conditions, and meanwhile daily training and assessment can be conveniently organized.

Description

technical field [0001] The invention belongs to the technical field of chemical teaching equipment, in particular to a simulation teaching device and system of an antioxidant production device. Background technique [0002] N,N'-di-sec-butyl-p-phenylenediamine (also known as antioxidant 4720), English abbreviation DBPD. Red to brown liquid, completely miscible with hydrocarbon oil, soluble in dilute inorganic acid, insoluble in dilute alkali and water. It is especially suitable as an additive for pyrolysis or pyrolysis gasoline (gasoline with high olefin content), which can effectively prevent olefins from oxidizing to produce gel, so as to avoid carbon deposits in combustion chambers, piston tops, cylinder heads and other parts during the use of oil products. Small amount, good anti-oxidation effect, greatly reducing environmental pollution. [0003] The industrial production method is the reductive alkylation of p-phenylenediamine, which uses p-phenylenediamine, methyl e...

Problems solved by technology

[0004] The high-pressure hydrogenation reduction production device and process in the production process of antioxidant 4720 is a large-scale experimental device and process flow that have not yet appeared in China. The high-risk nature of the high-pressure hydrogenation reduction reaction limits the training and practice of this type of production device , the hydrogenation devices in the existing chemical engineering practice teaching are all indoor equipment scaled according to the scale. Without real chemical production equipment, students can only cooperate with the internal and external operations of a single post, and cannot cooperate with the operation of the whole process , resulting in a single skill training, unable to give students a sense of reality of chemical installations, and difficult to meet the current training needs of compound talents in chemical production
