Description
Technical field
This utility model is related to a kind of polymerization ess and produces control device with the integrated emergency safety of dcs, especially to poly-
The control device of safety operation emergent management when symphysis abnormal during producing.
Background technology
At present, known polrvinyl chloride suspension polymerisation production Technology is very ripe.Technical process is: by chlorine
The raw materials such as vinyl monomer, deionized water, dispersant, initiator, auxiliary agent are pressed dcs setting program and are put into polymeric kettle, through certain bar
The reacted slurry of part is to be packaged through stripping, centrifugation, drying to the laggard pump that puts in storage of qualified products etc..Adopting above-mentioned technical process more
Dcs Distributed Control System controls, and ess is to participate in dcs to control polymerization emergency safety system together.Ess and the collecting and distributing control of dcs
System processed is made up of hardware and software, and wherein hardware includes field control station, active station, engineer station, communication netting twine etc.;Software
Including the dcs and ess configuration software of operating system platform and industrial controlling, ess used and dcs hardware configuration and software arrangements
Have nothing in common with each other, after integrated communication, wherein ess as all-the-way tracking dcs control in several critical process indexs parameter value, with kettle
Temperature, kettle pressure, stir current reach related setting value, urgent terminator button is pressed one of five satisfactions on live and auxiliary behaviour's platform
Ess device can be started, add terminator and open atmospheric valve according to rear condition, solve polymerization emergency in time.As day
This Yokogawa centum-cs3000 dcs Distributed Control System and rrosafe-rs ess safe emergency system also can be used for this and gather
Vinyl chloride process units.Above-mentioned technology directly applies to technique and its control that polymeric kettle produces polrvinyl chloride, and subject matter is
During former ess system malfunctions, dcs can not operate emergency blow-down device, so that security control is relatively difficult, is not only difficult to reach
To preferable production status, and extreme influence is caused to live personal safety and Environmental security.
Content of the invention
The purpose of this utility model technology be to provide a kind of easy to operate, can real-time monitoring, beneficial to safety in production, be suitable for
Polymeric kettle produces the control device of the integrated emergency safety of dcs and ess of polrvinyl chloride.
A kind of polymerization ess produces control device with the integrated emergency safety of dcs, controls adding of polymerization reaction kettle by dcs
Material → reaction → discharging overall process.After ess and dcs integrated communication, setting value a value is reached with kettle temperature, kettle pressure reaches setting value b
Value, stir current reach setting value c value, live emergency termination agent button is pressed, urgent terminator button is pressed on auxiliary behaviour's platform
One of lower condition five meets condition and can start the integrated emergency safety of ess and produces control device, and ess starts and adds terminator dress
Put and open emptying regulating valve and emptying stop valve according to polymeric kettle real-time condition, solve polymerization emergency in time, on
State ess and dcs to control switching is to newly increase automatic emptying device on auxiliary behaviour's platform: emptying stop valve and emptying regulating valve are in ess
With dcs control room switching push button, emptying device is started by dcs.
Because this utility model increased ess and dcs device on polymerization auxiliary operation platform, switching emptying device is put
Empty stop valve and emptying regulating valve button, in ess emergency safety operating system failure, emptying device is cut rapidly by operator
Change button incision dcs control system, emptying device is started by dcs, dcs can complete associative operation within the time the shortest, solution
The drawbacks of former emptying device of having determined can only be operated by ess controls standard so that emptying manipulation more can reach desired Safety, so that
Safe and steady operation it is ensured that and optimize operating procedure, also have simultaneously convenient to operation, mitigate labor strength, gram
Take the impact to polymerization for the anthropic factor, minimizing or fundamentally prevent accident rate, achieve polymerization key work
The automatically controlling, improve the advantages of parameter measure precision and control accuracy of sequence.This utility model can be widely applied to not
Emergency safety operating control device with polyreaction and polymerization process.

Specific embodiment
1-2 referring to the drawings, this utility model embodiment 1 controls the charging → reaction → discharging of polymerization reaction kettle for dcs
Process, wherein reaction end is to meet preset pressure value with pressure drop, you can judge that reaction terminates and adds terminator with end
Only polyreaction.In polymerization kettle temperature reach setting value a value be 70 DEG C, kettle pressure reach setting value b value 1.4mpa, stir current
Reaching setting value c value 30a is homophony parameter, and live emergency termination agent button is pressed, urgent terminator button quilt on auxiliary behaviour's platform
Press either button to be pressed;Five conditions meet one of them, you can judge that polymerization exception ess starts and adds termination
Agent is to terminate polyreaction.Ess emergency safety operating system is primarily directed to abnormal conditions start-stop in polymerization production process
Agent adding apparatus.Ess system is made up of hardware and software with dcs Distributed Control System, and wherein hardware includes field control station, behaviour
Stand, engineer station, communication netting twine etc.;Software includes ess the and dcs configuration software of operating system platform and industrial controlling,
This technology directly applies to technique and its control device that polymeric kettle produces polrvinyl chloride.
Embodiment 2 difference from Example 1 is: in polymerization production process, ess and the integrated emergency safety of dcs produce control
Device processed, increases switching emptying device emptying stop valve and emptying regulating valve between ess and dcs device on auxiliary operation platform and presses
Button, can be respectively started emptying device by dcs and ess.
Preset temperature in above-described embodiment, pressure, current reference value can rule of thumb need to take multiple, concrete value with
The size of reaction kettle device, response characteristic etc. have particularly important relation.
This utility model mainly has been made to improve to the hardware unit in emptying stage, other identical with prior art.
