Referring to Fig. 2, the present embodiment further relates to a kind of nuclear power MVR automation control methods, including：
Step 21, initialization data, resets all valves, and monitoring device wind pressure and condensation liquid case liquid level；
Step 22, start hot wind pumping system, equipment is vacuumized, when being down to 90KPa in 30 seconds, open butterfly valve and into Material valve starts to feed；
Step 23, when charging liquid level reaches high liquid level, stop charging, begin to warm up, when feed temperature and vapor (steam) temperature Reach design temperature and stop heating；
Step 24, butterfly valve is closed, the down periods eliminate whether pressure in feed liquid bubble and detection device is less than 0.05MPa, If being then recycled into step 2, otherwise, into next step；
Step 25, when butterfly valve is closed in place, opening condensation fluid valve carries out liquid material concentration, when liquid level is concentrated to low liquid level Inlet valve fluid infusion is opened, when liquid level reaches high liquid level after fluid infusion, is then again switched off inlet valve, when liquid level is concentrated to time of low liquid level When number reaches preset times, discharge is shut down.
In the liquid material concentration process of step 25, when liquid level triggers high liquid level in cooling cylinder, then condensate liquid valve is closed, to cold Lime set case carries out discharge opeing, when cooling cylinder internal trigger low liquid level, stops discharge opeing, reopens condensate liquid valve.
In method, according to temperature in equipment, including：
When 100 DEG C of ＜ T≤113 DEG C, heat dissipation valve opens 1s every 5s；
When 113 DEG C of ＜ T≤118 DEG C, heat dissipation valve opens 1s every 3s；
As 118 DEG C of ＜ T, heat dissipation valve maintains a normally open；
As 135 DEG C≤T, alarm is shut down.
Step 26 is further included, opens water pump, the water filling into equipment, opens each valve and is cleaned successively, after cleaning, Switch off the pump discharge opeing.
The operation rules in above-mentioned steps 1- steps 6, mode etc. will be described in detail below, concrete configuration is with reference to upper State table 1- tables 4.
Wherein step 21 is specially：
(1) main program starts：Power turn-on, system enter standby mode, display main program interface.
(2) instrumentation wind pressure：If PSJ401 ＜ 40KPa, all valve resets, sound-light alarm, and prompt user： " instrument wind pressure is low " (F26)；If PSJ401 ＞ 80KPa, all valve resets, sound-light alarm, and prompt user：" instrument wind Pressure is high " (F27).
(3) condensation liquid case liquid level is checked：If LS4012 has been triggered, all valve resets, sound-light alarm, and prompt to use Family：" condensation liquid case filling liquid must be given " (F14).
(4) when system is in standby mode, operational order can be received, and monitors each data in real time, is had beyond setting value When, alarm or carry out relevant action.
Step 22 is specially：
Wind turbine automatically turns on, and system is vacuumized, rotating speed 2935RPM.
When PT4035 was down to 90KPa (a) in 30 seconds (not up to then alarm shut down (F10) if, absolute pressure in overall process Power≤45KPa (adjustable), which then alarms to shut down in (F11), overall process, shows pressure measuring value (F12)), automatically open up butterfly valve V4005, inlet valve V4001, start to feed to device, when liquid level reaches LS4002 high liquid levels, self-closing valve V4001, stops Only feed liquor (being all not up to LS4002 high liquid levels after ten minutes then to alarm shutdown (F1)).
Step 23 is specially：
Feed liquor is to after LS4002 high liquid levels, automatically into heating mode.
Compressor continues to run with, and automatically opens up and directly heats valve V4017, when the feed temperature that TE4021 is shown reaches 84 DEG C The vapor (steam) temperature that (adjustable) and TE4022 are shown switchs to translative mode when reaching 80 DEG C (adjustable).
Step 24 is specially：
When TE4021 institutes temperature displaying function, which reaches 84 DEG C and TE4022 institute's temperature displaying functions, reaches 80 DEG C, V4017 is automatically closed, and enters Translative mode, V4005 automatic slowlies close (the whole shut-in time lasts about 54S), during which check whether PT4035 is less than Whether 0.05MPa (a), LS4003 detect foam：If PT4035 is less than 0.05MPa (a), V4005 is automatically opened up again, V4005 repeats the above process action, until V4005 is completely closed；If LS4003 detects foam, V4013 valves automatically turn on Defoamed.
Step 5 is specially：
V4005 is completely closed, and condensate liquid valve V4010 is automatically opened up, into concentration formats.Liquid level gauge LS4002 control chargings The switch of valve V4001, carries out fluid infusion：When liquid level reaches LS4002 low liquid levels, valve V4001, which is automatically turned on, carries out fluid infusion；Work as liquid When position reaches LS4002 high liquid levels, valve V4001 is automatically closed stopping fluid infusion and (is not up to LS4002 high liquid levels after ten minutes then to alarm Shut down (F1)).When LS4002 low liquid level signals send setting number (adjustable), V4001 is no longer opened, and system is automatically into stopping Machine discharges operating mode.
In concentration process, when condensing LS4005 triggerings in liquid case, valve V4010 is automatically closed, and valve V4011, V4046 are automatic Open, discharge opeing is carried out to condensation liquid case；When condensing LS4012 triggerings in liquid case, valve V4011, V4046 are automatically closed, valve V4010 is automatically turned on.Condensation liquid case discharge opeing process occurs repeatedly.
After system enters shutdown discharge mode, wind turbine automatic shutdown, valve V4006, which is automatically closed, (is not up to close stance after 5s Put then alarm (F5)), V4015 is automatically turned on, and when PT4035 pressure reaches 140KPa (a), (pressure is not up to then reported after 5min Alert (F9)) (PS4036 pressure >=170KPa (a) is then shut down, and self-closing valve V4015, opens valve V4005, and valve V4011 is jumped to Lead directly to 1 (F13)), V4028 is automatically turned on, and concentrate is discharged into laboratory and steams raffinate collecting box by compressed air, after 2min, V4015, V4028 are automatically closed, and V4006 is automatically turned on.
Step 26 is specially：
V4028 is automatically opened up, and triple valve V4011, V4012 jump to by-passing valve position 2 automatically after 5s, V4011, V4012 after 10s Automatic rebound straight-through valve position 1, V4047 is automatically opened up after 5s, and V4047 is automatically closed after 5s, and V4028 is automatically closed after 5s.Then Valve V4022, V4038, V4039, V4047 are automatically opened up at the same time：When LS4010 detects that signal or V4038 opening times expire 1min Afterwards, valve V4038 is automatically closed；After LS4003 detects signal or V4039 opening times expire 1min, valve V4039 is automatically closed； After LS4004 detects signal or V4022 opening times expire 1min, valve V4022 is automatically closed；When V4047 opening times are expired After 1min, valve V4047 is automatically closed.Then V4028 is automatically opened up, and V4022, V4038, V4039, V4047 are beaten automatically after 2min Open, V4022, V4038, V4039, V4047 are automatically closed after 30s, and V4028 is automatically closed after 5s.
Method further includes manual control, by operating the corresponding button, can open or close each operated pneumatic valve, can also start or Stop hot wind pump etc., be only used for the debugging and maintenance of system.
In conclusion the control system uses PLC and upper industrial personal computer as core, to the work of small-sized heat pump vaporising device Skill, equipment state, process variable and data are analyzed, and realize the automation switching and the start and stop of equipment of flow；To technique mistake Journey and equipment carry out interlock protection；Operation data record filing to system；Can also realize engineering site local operation and Data are checked；Meanwhile logged in by remote data collection of server and subscription client and inquire about real-time and historical data；System is also Realize machine charging, heating, conversion, concentration, process defoaming, shut down discharge, cleaning function full-automatic and height intelligence Change, reach safety, economic, environmental protection effect.
