Description
Technical field
The present invention relates to a kind of school workshop of chemical field, belong to education, chemical process and equipment technical field, for the teaching of universities and colleges of enterprise chemical and relevant speciality, training, practice, and carry out the training of chemical technician and senior technician.
Background technology
Due to singularity (inflammable, explosive, poisonous, harmful and high temperature, the high pressure etc. of chemical industry.), be not suitable for carrying out on commercial plant carrying out practising, in practice-training teaching training.Expense and safety be also must consider factor (its raw materials consumption, energy consumption etc., does is key that how a large amount of product processes in repetition training?).And chemical products are of a great variety, its synthetic method is not quite similar.Same raw material can produce different chemicals, and identical product can be produced by different raw materials, and its technique of the product line of same raw material is also incomplete same.So the teaching of universities and colleges, training, practice generally adopt a certain categorizing selection to carry out, as fixed bed reactors, fluidized-bed reactor, tank reactor etc.; Or themopositive reaction, thermonegative reaction etc.Following three kinds are roughly had at present: the first goes chemical enterprise to practise exactly for chemical teaching, training, student can be familiar with chemical plant, instrument at this and be familiar with chemical production technology flow process, but student can only see inactive, be also just far from being and improve operative skill; The second is exactly popular completely virtual chemical plant installations (i.e. simulation software) for many years, in kind without any chemical plant, only can carry out pseudo operation on computers, it is less to drop into little operating cost, and safety energy-conserving environment protection, all there are this teaching software in most of universities and colleges; The third is the chemical plant installations built in lyceum, has real chemical plant, simulation instrument and simulation operations software, does not throw industrial chemicals, do not produce chemical products.Student can be familiar with chemical plant, instrument and be familiar with chemical production technology flow process on this device, can also carry out simulation operations.Except input ratio the first greatly except, its operating cost etc. are close with the second.Owing to being at simulation operation apparatus, student train in such circumstances just have false sensation (with play games the same, mistake rebegins, and can not produce the consequence that true chemical plant installations is such, that is so training is difficult to drop into, and does not have the sense of duty on the spot in person.）。There is very large difference in actual device and analogue means, if the emulation of its abnormal occurrence is that people presets, and actual device is produced by many reasons, is difficult to practise real skill.
Summary of the invention
The object of this invention is to provide a kind of styrene school workshop for teaching, training, to solve falseness, real not problem that existing analogue means exists.
For achieving the above object, the present invention is by the following technical solutions:
For a styrene school workshop for teaching, training, it is characterized in that: comprise chemical plant installations production area, chemical plant installations control zone, teaching Discussion district.
Wherein, small-sized Styrene Process is had in chemical plant installations production area, small-sized Styrene Process comprises chemical plant, chemical instruments and device frame, device frame is steel platform, chemical plant, chemical instruments are arranged on steel platform, and chemical instruments are connected by pipeline and cable with chemical plant;
Control zone is made up of switch board, industrial computer, is connected by signal cable with above-mentioned small-sized Styrene Process;
Teaching Discussion district comprises student's computer, multimedia teaching facility and simulated operation software.
Described chemical plant comprises: test tank, vaporization reactor, quencher, receiving tank, tail cooler, fluid level transmitter, pressure unit, solenoid valve, electric control valve etc.
Further, vaporization reactor is made up of upper and lower two parts, and top is carburetor, bottom is reactor.Upper and lowerly establish 2 temperature sensors, separately control temperature.
Further, the switch board in described control zone is made up of domestic instruments, comprises intelligent regulator, multichannel measurement alarm etc.
Industrial computer is by the control procedure of domestic configuration software configuration implement device, there is the Three Dimensional Interface of animated function, also there is real-time data acquisition, function that data history preservation, realtime curve, the inquiry of historical data, report query, Drawing of Curve, form curve printing, pid parameter are adjusted.
Further, simulated operation software is the same with device function software to be realized by domestic configuration software configuration, and operation interface and active station interface phase are together.
The invention has the beneficial effects as follows: structure of the present invention is undertaken reducing design by commercial plant, and making and installation, true to embody, be only the difference of output size, solve that commercial plant floor area is large, investment is large, operating cost is high and the problem of safety factor.Utilize the invention process to impart knowledge to students, student can be allowed to operate real chemical production device, improve the understanding of student to chemical plant and device, the operant level of student can be improved, cultivate collaboration capabilities and the sense of community of student.Effectively can alleviate the ubiquitous one-house show of current school, find the problem of the drawback of enterprise's real training difficulty.Trainee carries out the checking of the driving of device, parking, accident treatment operation and technological parameter in the school, is the training condition that industrial enterprise can not provide.
