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 teaching, training, the practice of universities and colleges of enterprise chemical and relevant speciality, and carry out chemical technician and senior technician's training.
Background technology
Due to the singularity of chemical industry (inflammable, explosive, poisonous, harmful and high temperature, high pressure etc.), practising, in practice-training teaching training, be not suitable for carrying out on commercial plant.Expense and safety be also the factor that must consider (its raw materials consumption, energy consumption etc., does is key that how a large amount of products are processed in repetition training?).And chemical products are of a great variety, its synthetic method is not quite similar.Same raw material can be produced 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.For chemical teaching, training, roughly there are following three kinds at present: the first is gone chemical enterprise practice exactly, student can be familiar with chemical plant, instrument and be familiar with Chemical Manufacture technological process at this, but student can only see inactive, be also just far from being and improved operative skill; The second is exactly popular complete virtual chemical plant installations (being simulation software) for many years, in kind without any chemical plant, only can carry out on computers pseudo operation, drop into little operating cost less, and safety energy-conserving environment protection, all there is this teaching software in most of universities and colleges; The third is the chemical plant installations of building in lyceum, has real chemical plant, emulation instrument and simulation operations software, does not throw industrial chemicals, does not produce chemical products.Student can be familiar with chemical plant, instrument and be familiar with Chemical Manufacture technological process on this device, can also carry out simulation operations.Except input ratio the first greatly, its operating cost etc. are close with the second.Owing to being at simulation operation apparatus, student under this environment, train just have false sensation (with play games equally, wrong rebegin, can not produce the such consequence of true chemical plant installations, that is to say that training like this is difficult to drop into, do not have the sense of duty on the spot in person.）。There is very large difference in actual device and analogue means, if its abnormal occurrence emulation is that people is predefined, 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, with solve existing enterprise's device can only see inactive, and analogue means exists false, real not problem.
For achieving the above object, the present invention is by the following technical solutions:
A styrene school workshop for teaching, training, is characterized in that: comprise the on-the-spot district of styrene school workshop, the teaching Discussion district of the control zone of styrene school workshop, styrene school workshop.
Wherein, the on-the-spot district of styrene school workshop comprises non-standard equipment, standard device and device frame, and device frame is steel platform, and non-standard equipment, standard device are arranged on steel platform, and non-standard equipment, standard device connect by pipeline and cable.
The control zone of styrene school workshop is comprised of switch board, industrial computer, is connected by cable with above-mentioned standard device.
The teaching Discussion district of styrene school workshop comprises student's computer, multimedia teaching facility.
Described non-standard equipment comprises: test tank, vaporization reactor, quencher, receiving tank, tail cooler; Standard device comprises: fluid level transmitter, pressure unit, solenoid valve, electric control valve.
Further, vaporization reactor is comprised of upper and lower two parts, and top is that carburetor, bottom are reactor.Upper and lowerly establish 2 temperature sensors, separately control temperature.
Further, the switch board in the control zone of described styrene school workshop is comprised of domestic instruments, comprises intelligent regulator, multichannel measurement alarm.
The invention has the beneficial effects as follows: structure of the present invention is to dwindle design by commercial plant, and manufacture and install, true to embody, be only the difference of output size, solved that commercial plant floor area is large, investment is large, operating cost is high and the problem of safety factor.Utilize the invention process teaching, can allow student operate real Styrene Process, improve the understanding of student to chemical plant and device, can improve student's operant level, cultivate student's collaboration capabilities and sense of community.Can effectively 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 driving, parking, accident treatment operation and the technological parameter of device in the school, is the training condition that industrial enterprise can not provide.
