Embodiment
Below in conjunction with accompanying drawing, a kind of organic amine desulfurization acid-making process Distributed Control System (DCS) of the present utility model is described in detail.
Referring to Fig. 1, a kind of organic amine desulfurization acid-making process Distributed Control System (DCS) 1 of the present utility model comprises signal pickup assembly 10, the controller 8 being connected with signal pickup assembly 10 by I/O module 9, the host groups being connected with controller 8, for control system 1 provides the supply unit 7 of power.This control system 1 adopts multisegment structure, and the corresponding domain addresses of each network segment of multisegment is separate between domain addresses, can carry out independent operation to techniques such as desulfurization, sulphur processed, and whole system operation is more efficient.
Preferably, according to process system flow process, be first divided into three process control network segments (territory): the desulfurization main flow network segment 2, the water treatment network segment 3, gas washing in SA production and the conveying network segment 4.Three network segments are three territories, distribute to different domain addresses, thereby make between each territory separate.And then further grouping in each independent domains, for example in the desulfurization main flow network segment (territory), by synergic system, be divided into again independently three groups again, in each independent groups 5, be respectively equipped with a set of independently signal pickup assembly 10, I/O module 9, controller 8, communication line, power supply 7 and control rack, between each territory and each group, on controlling, can accomplish not interfere with each other.
In system 1 of the present utility model, a large amount of exchanges data is controlled in separately carries out in the network segment, between different segment, only exchange low volume data, even if thereby guarantee that each segment data communication load also can meet code requirement and have system extension ability the busiest in the situation that, even if the arbitrary system or equipment being connected on data communication system breaks down, can not cause communication system paralysis yet or affect the work of other networked system and equipment.
With reference to Fig. 2, as an embodiment of the present utility model, in gas washing in SA production of the present utility model and the conveying network segment 4, I/O module 9 is two-way redundancy I/O module.Measuring-signal is no longer directly to access standard I/O module on the spot, but first access redundancy conditioning plate 11, each road measuring-signal of 11 pairs of receptions of redundancy conditioning plate, conditioning is output as two groups of (road) redundancy output signals, be connected to respectively again two standard I/O modules 12, formed redundant input, the principle of redundancy output therewith roughly the same.To the redundancy RTD signal of Application and Development not yet, adopt first conversion again the method for access solve, access again redundancy AI module after first RTD signal being transferred to standard A I signal, thereby reach whole redundant configuration requirements of chemical industry.
The configuration of redundancy I/O module and configuration have reached the monitoring requirement of relieving haperacidity chemical process completely, make to introduce chemical process flow and become a reality in electric power generation system, for electric power and the chemical industry mutual fusion of monitoring function are between the two laid a good foundation.
As another embodiment of the present utility model, in each independent network segment, be equipped with an engineer station 6.Each performs its own functions for each engineer station 6, more strengthened the independence of different segment work.An engineer station 6 is established in conventional desulfurization, and Bing Yu operator station is connected in network side by side, once communication system fault, engineer station can not carry out its function.In the utility model, each network segment is respectively established an engineer station 6, and changes into and transfer to process control station on network connects, and is directly connected with process control station, even if supervisory layers breaks down like this, engineer station still can normally complete its systemic-function.
As another embodiment of the present utility model, the organic amine desulfurization acid-making process that Distributed Control System (DCS) 1 is controlled comprises oxygen ozone process, and the control of oxygen ozone process is included in to Distributed Control System (DCS) 1.Conventional power plant desulfurization water treatment portion is only Waste Water Treatment, and the utility model is the newly-increased filtration of amine liquid, APU and demineralized water subsystem again, and wastewater treatment removes common process and increased again oxygen ozone subsystem newly.These newly-increased subsystems got used to adopting PLC system monitoring in the past, this project all unifies to include in DCS monitoring by each subsystem, cancel PLC, make a whole set of desulphurization system can adopt unified hardware, software and configuration method, thereby the kind that has greatly reduced standby redundancy effectively reduces operation expense in the future, also reduced operation maintenance workload, training also becomes simply simultaneously, and operation person can very fast on duty controlling.
In the utility model, it is very frequent that in oxygen ozone subsystem, some valve switches action, high to controller 8 scan periods requirement, adopted PLC to realize monitoring in the past always.The normal scan cycle of DCS controller (DPU) is 500ms, and the utility model is cancelled after PLC, in DCS configuration, for this subsystem, establishes independently DPU and its scan period is brought up to 100ms, and other DPU still adopts the normal scan cycle.After putting into operation, between each DPU, do not produce conflict, stable, realized the control requirement of instrument factory.The utility model adopts identical control method, for different subsystems, takes different sweep frequencies further to simplify control program, raises the efficiency, cost-saving.
Organic amine desulfurization acid-making process Distributed Control System (DCS) 1 of the present utility model is first divided network structure the independent network segment to divide group independently again, peripheral workshop is adopted to the collocation method at Long-distance Control station by technological process, making arbitrary network segment fault all can not affect other network segment normally works, while making arbitrary stove desulfurization fault, do not affect the normal operation of another stove desulfurization, arbitrary row relieving haperacidity fault does not affect the production of another row relieving haperacidity.Effectively guarantee system energy safety, operation continuously reliably.
At each network segment, respectively configure an engineer station 6, to I/O scale huge desulfurization DCS like this, give prominence to debug process convenient, fast, effectively and aspect not interfereing with each other, be also convenient to very much adjustment and the maintenance work of process system in the future or DCS system simultaneously.
The water treatment system also unified DCS of employing is controlled without PLC, make a whole set of desulphurization system can adopt unified hardware, software and configuration method, thereby the kind that has greatly reduced standby redundancy effectively reduces operation expense in the future, also reduced operation maintenance workload simultaneously, training also becomes simply, and operation person can very fast on duty controlling.Adopt a kind of organic amine desulfurization acid-making process Distributed Control System (DCS) of the present utility model 1 control method simple, move efficient, with low cost, system extension ability is strong, subsystem work is independent, easy to maintenance, the system that can effectively guarantee can safety, operation continuously reliably.
The utility model is not limited to above-mentioned embodiment, and the system that every employing is identical or approximate with the utility model above-described embodiment, and other the organic amine desulfurization acid-making process Distributed Control System (DCS) obtaining, all within protection domain of the present utility model.
