Interrogate the data for the rear end process 6 that module 216 is transmitted.
Front end interlocking modules 217, the interlocking modules 219 that gather dust, water supply interlocking modules 220 and rear end interlocking modules 221 are equal
It is connected with safety interlocking module 222, and will be wherein interlocked respectively with the relevant signal of waste heat boiler with safety interlocking module 222,
And safety interlocking module 222 is according to front end interlocking modules 217, the interlocking modules 219 that gather dust, water supply interlocking modules 220 and rear end
The analysis result of interlocking modules 221 judges the operating mode of front end smelting procedure 2, process of gathering dust 4, water process 5 and rear end process 6
Whether change, and interlocking is controlled waste heat boiler 1 according to judging result or releases exterior interlocking, so as to improper
Waste heat boiler during work provides safeguard protection.
Specifically, if any process in front end smelting procedure 2, process of gathering dust 4, water process 5 and rear end process 6
Operating mode change, waste heat boiler controller 21 is controlled interlocking by safety interlocking module 222 to waste heat boiler 1；Instead
It, is if front end smelting procedure 2, process of gathering dust 4, the operating mode of water process 5 and rear end process 6 do not change, waste heat
Boiler controller 21 releases waste heat boiler 1 exterior interlocking by safety interlocking module 222, still using conventional control model pair
Internal unit is controlled.
It should be noted that " operating mode " in the present invention refers to the fortune of equipment or material under the course of work in a certain process
Row state, can be monitored and Data Collection in several ways, and by itself and the operating status and work under course of normal operation
Contrasted as parameter, so as to judge whether it changes.For example, if the parameters of a certain operating mode are each fallen within normally
In the range of, then it is assumed that the operating mode does not change；Conversely, if one or more parameters of a certain operating mode are beyond normal range (NR),
Then think that the operating mode is changed.
The detection signal that receiving module 212 is used to receive 1 correlate meter of waste heat boiler (includes but not limited to regulating valve 8, vapour
Bag fluid level transmitter 10, drum pressure transmitter 11, flue temperature element 13, rapping apparatus 14, circulating pump control cabinet 16, drum
Feedwater flow transmitter 17, drum steam (vapor) outlet flow transmitter 20), and signal transmission will be detected to monitoring module 218；Control
Module 213 receives the data from monitoring module 218, and to relevant device (regulating valve 8, the rapping apparatus inside waste heat boiler
14th, circulating pump control cabinet 16) it is controlled；Monitoring module 218 is used to be detected control to waste heat boiler itself, judges waste heat
Normally whether boiler 1 be controlled and run after interlocking, while is interlocked with safety interlocking module 222.
For example, when containing carbonated drink in waste heat boiler drum 7, waste heat boiler controller 21 is manipulated by control module 213
Regulating valve 8 is adjusted at any time, and guarantee is in normal range (NR) for a long time；Contain a large amount of high-temperature flue gas when waste heat boiler flue 3 is interior
When, waste heat boiler controller 21 manipulates rapping apparatus 214 by control module 213 and periodically cigarette ash is purged, while basis
Flue temperature judges real-time working condition, and rapping frequency is adjusted according to operating mode；In normal production, waste heat boiler controller 21 passes through control
Molding block 213 sends circulating pump control cabinet 16 signal, the start and stop of control loop pump 9, while judges to follow by receiving module 212
The operating status of ring pump 9.
Therefore, monitoring module 218 records current system data at any time, in receiving module 212 it is received detection signal with
Control setting value contrasted after, according to control module 213 be transferred to regulating valve 8, circulating pump 9 and rapping apparatus 14 and to its into
Row manipulation, it is ensured that the working status of each controllable device is under normal condition all the time, and monitoring module 218 sends " normal " letter at this time
Number to safety interlocking module.In addition, once dangerous situation, the monitoring modules such as occurrence of equipment failure or detection signal are exceeded can be sent
" alarm！" signal, it is quickly sent to safety interlocking module 222 and starts interlocking, it is ensured that safety in production.
Work of the waste heat boiler controller 21 to front end smelting procedure 2, process of gathering dust 4, water process 5 and rear end process 6
When condition is judged, if the process auxiliary facility that gathers dust has been turned on, the process controller 15 that gathers dust can prompt " allowing to start " and will letter
Number communication is sent to waste heat boiler controller 21；If water process auxiliary facility has been turned on, water process controller 18 can prompt " to permit
Perhaps start " and give signal communication to waste heat boiler controller 21；If rear end process auxiliary facility has been turned on, the control of rear end process
Device 19 can prompt " allowing to start " and send signal communication to waste heat boiler controller 21.
Waste heat boiler controller 21 by each communication module 214,215,216 receive process 4 of gathering dust, water process 5 and
After 6 process of rear end process " allowing to start ", the control cabinet 16 of circulating pump 9 is manipulated by control module, it is ensured that circulating pump 9
It is normal to start, while " will allow to start " signal and give to front end smelting procedure controller 12, proceed by the normal of overall project
Production.
During production run, waste heat boiler controller 21 at any time by the operating status that monitoring module 218 collects send to
Front end smelting procedure controller 12, water process controller 15, gather dust process controller 18 and rear end process controller 19, such as
Flue-gas temperature, rapping apparatus operating status are sent to the process controller 15 that gathers dust, steam pressure, its own system operating status are sent
To rear end process controller 19.
Once water process controller 15 or rear end process controller 19 prompt " alarm！", waste heat boiler controller 21 will
Alarm is prompted to front end smelting procedure controller 12, reduces feeding quantity, while opens the steam evacuation valve on drum, reduces and steams
Vapour discharge capacity.Once the process controller 18 that gathers dust prompts " alarm！", waste heat boiler controller 21 will increase rapping frequency.It is remaining
1 internal unit of heat boiler breaks down, and same operation can be also carried out, to reduce security risk.
During production run, waste heat boiler controller 21 and front end smelting procedure 2, process of gathering dust 4, water process 5
And rear end process 6 is in interactive state all the time.
To sum up, the main function of waste heat boiler controller 21 is to add waste heat boiler in waste heat boiler control system
The relevant information of periphery all process steps, the internal data after the significant data of each operation in real time collection with waste heat boiler 1 is carried out
Interlocking, both can guarantee that waste heat boiler can stable operation, while improve disposal ability of the system to security risk, reduce safety wind
Danger.
