Present invention also offers a kind of converter mouth differential pressure adjusting method with fuzzy Prediction compensation, including following step
Suddenly：
The first step, differential pressure measuring mechanism is transferred to measuring state from nitrogen purging state；
Second step, pass sequentially through high low speed controller, adder A, Frequency Converter Control dedusting fan and carry out 1500 r/min operatings；
3rd step, the air pressure numerical value of comparator is set as ± 20Pa；
4th step, converter start to smelt, and when the oxygen rifle of converter drops to workspace, the oxygen rifle of converter declines sensor and detects oxygen
After rifle enters workspace, electric signal passes to oxygen rifle signaling switch, oxygen rifle signaling switch closure, differential pressure can be obscured
The controlling organization of predictive compensation obtains electric forming loop, meanwhile, pass sequentially through high low speed controller, adder A, Frequency Converter Control and remove
Dirt blower fan carries out 2700 r/min high rotating speed operation；
5th step, fire door micro-pressure-difference, converter mouth elementary errors pressure signal Y are detected by 4 pressure tappings of differential pressure measuring mechanism
After differential pressure measuring mechanism measures conversion, fuzzy Prediction compensator is delivered to all the way, another way is with fuzzy Prediction compensator through fortune
The value y exported after calculation, value y enter adder B with first via delivery value, and add operation is done by adder B, and afterwards, adder B will
Operation values export carries out difference to comparator, comparator by the fire door atmospheric pressure value ± 20Pa that obtained operation values and step 3 input
Computing obtains operation values e；
6th step, when the difference that comparator is drawn in step 5 is less than -20Pa or during higher than+20Pa, comparator is by operation values e
It is sent into converter differential pressure fuzzy controller and carries out computing, converter differential pressure fuzzy controller send the signal value U obtained after computing
Enter data alignment unit and be finely adjusted amendment, be sent into adder A afterwards and carry out add operation, computing with the high rotating speed in step 4
As a result export to frequency converter, the rotating speed of dedusting fan is adjusted by frequency converter to be reduced or raise, while repeat step five, step
The operation values e that comparator obtains in five is sent into converter differential pressure fuzzy controller and carries out computing, converter differential pressure fuzzy controller
The tunnels of signal value U mono- obtained after computing feeding data alignment unit is finely adjusted amendment, is sent into adder A and step 4 afterwards
In high rotating speed carry out add operation, operation result exported to frequency converter, and passing through frequency converter and adjusting the rotating speed of dedusting fan reduces
Or rise, another way is sent into the step of fuzzy Prediction compensator participates in repeating again five, until comparator in step 5
When carrying out difference operation and obtaining operation values e=0, show that fire door pressure is in ± 20Pa control range, converter differential pressure obscures
Controller obtains operation values e=0, stops operation control immediately.
The pressure value that the present invention is monitored according to differential pressure measuring mechanism, fuzzy Prediction is transferred to by the pressure value respectively
Compensator and adder B, after carrying out analytic operation to signal data by fuzzy Prediction compensator, to adder B output signal
After y, signal y are conveyed to adder B signal progress add operation with differential pressure measuring mechanism, operation values are sent to and compared
Device, it can show that fire door coal gas is all recovered the fire door atmospheric pressure value for not occurring flue gas and leaking due to have input in advance to comparator
± 20Pa, therefore, comparator by the operation values received compared with atmospheric pressure value ± 20Pa, difference that comparator is drawn less than-
20Pa or during higher than+20Pa, operation values e is sent into converter differential pressure fuzzy controller and carries out computing, converter elementary errors by comparator
The signal value U that pressing mold fuzzy controllers will obtain after computing, in order that the signal value U of converter differential pressure fuzzy controller output is more
Accurately, therefore by signal value U feeding data alignment units amendment is finely adjusted, makes its precision, the signal after precision is successively
By adder A, frequency converter, to control the rotating speed of dedusting fan, using the speed of dedusting fan rotating speed, protect fire door pressure value
Hold in ± 20Pa, differential pressure measuring mechanism in the running, monitors fire door pressure value, and pressure value is conveyed into mould in real time in real time
Paste predictive compensation device, adder B, real time data contrast carried out by comparator, and to converter differential pressure fuzzy controller not between
It is disconnected to send operation values, after converter differential pressure fuzzy controller is analyzed operation values, divide two-way to send signal value U, all the way
Be sent to data alignment unit, data alignment unit data are refined after by adder A, frequency converter, to control dedusting wind
The rotating speed of machine, when differential pressure measuring mechanism detects current fire door pressure still not in ± 20Pa, differential pressure measuring mechanism
Fuzzy Prediction compensator, adder B are sent a signal to again, and now, on the one hand fuzzy Prediction compensator receives differential pressure survey
The signal that measuring mechanism occurs, the second road signal value U of converter differential pressure fuzzy controller transmission is on the other hand also received, obscured
Two paths of signals after treatment, is formed thermal compensation signal by predictive compensation device, and thermal compensation signal enters adder adder B, adder B
After two paths of signals is added, comparator is sent to, comparator carries out the signal received and the atmospheric pressure value ± 20Pa being previously entered
Compare, when the difference that comparator is drawn is less than -20Pa or higher than+20Pa, operation values e is sent into converter elementary errors pressing mold by comparator
Fuzzy controllers carry out computing, and the signal value U that converter differential pressure fuzzy controller will obtain after computing, signal value U are sent into data and adjusted
Whole unit is finely adjusted amendment, and the signal after precision passes sequentially through adder A, frequency converter, to control the rotating speed of dedusting fan,
Differential pressure measuring mechanism receives pressure signal again, and transfers out signal, and fuzzy Prediction can be carried out to differential pressure by being again introduced into
The controlling organization of compensation, until the signal received and the atmospheric pressure value ± 20Pa that is previously entered are compared by comparator, comparator
Difference e=0 drawn, show that fire door pressure is in ± 20Pa control range, converter differential pressure fuzzy controller obtains computing
Value e=0, stops operation control immediately.
The beneficial effects of the invention are as follows：
1st, the present invention directly controls dedusting fan rotating speed by fuzzy algorithmic approach, overcomes conventionally employed second Venturi tube aditus laryngis R-D
Valve valve plate is easily by dirty flue gas clamping stagnation, the problem of causing differential pressure regulating system out of control.
2. due to invention avoids the hydraulic drive mechanism because of R-D valves, therefore effectively reduce fault rate and safeguard skill
Art component difficulty.
3rd, can effectively be overcome because of dedusting fan blower fan as a result of the control method compensated with fuzzy Prediction, the present invention
The long influence lagged to automatically controlling quality between micro-differential pressure power.
4th, the present invention is changed traditional blower fan and determined by the rotating speed continuous control during converter smelting to dedusting fan
Rotating speed is controlled, and the power consumption loss of blower fan is effectively reduced while accurately control micro-differential pressure power.
