Description
Technical field
The utility model relates to a kind of dedusting motor speed automatic regulating system, belongs to metallurgy industry dedusting motor device technical field.
Background technique
In iron and steel enterprise, Fan Equipment load is large, energy consumption is high, widely apply in ironmaking, steel-making dust pelletizing system, long-time continuous operation, the tradition method of operation is that the motor speed of dedusting fan is constant, utilize valve control air quantity to regulate, cause valve to damage, workload is large etc. is unfavorable for that the situation of producing occurs, and power consumption is large.Afterwards, frequency variator starts to be applied in dedusting fan motor, utilize frequency variator voltage regulation and frequency modulation to control the rotating speed of dedusting fan motor, but conventionally by virtue of experience artificially regulate the frequency of frequency variator, this method complex operation, can not control the discharge amount of atmospheric pollutant in flue gas, saving power to greatest extent accurately, precision is poor, is difficult to meet the needs of dedusting reality.
Model utility content
The utility model object is to provide a kind of dedusting motor speed automatic regulating system, by the content of the continuous air pollution monitoring thing of fume emission monitor, automatically controls the motor speed of dedusting fan, solves the problem existing in background technique.
The technical solution of the utility model is:
A kind of dedusting motor speed automatic regulating system, comprise fume emission monitor, controller, frequency variator, motor and blower fan, fume emission monitor is connected by communication data line with controller, controller output signal is connected with frequency variator, motor and blower fan successively by communication data line, and frequency variator, motor and blower fan feedback signal are connected with controller respectively by communication data line.
The given signal of described controller is standard limit of smog release.
Adopt the utility model, with the content of the continuous air pollution monitoring thing of fume emission monitor, by data transmission in controller, controller is through going out to the feedback signal computational analysis of these data and motor speed and frequency variator operation frequency the frequency that frequency variator will be exported, arrive frequency variator through data transmission, the rotating speed of the incoming frequency control motor of process frequency variator, thus the rotating speed of drive blower fan is satisfied the demand.
The beneficial effects of the utility model are: can automatically control according to the content of atmospheric pollutant the motor speed of dedusting fan, and save power to greatest extent, and meet the demands, there is science, advance, applicability and replicability.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
In figure: fume emission monitor 1, controller 2, frequency variator 3, motor 4, blower fan 5.
Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
With reference to accompanying drawing 1, a kind of dedusting motor speed automatic regulating system, comprise fume emission monitor 1, controller 2, frequency variator 3, motor 4 and blower fan 5, fume emission monitor 1 is connected by communication data line with controller 2, controller 2 output signals are connected with frequency variator 3, motor 4 and blower fan 5 successively by communication data line, frequency variator 3, motor 4 and blower fan 5 feedback signals are connected with controller 2 respectively by communication data line, according to the granular material discharged standard of steel-making, ironmaking, sintering and steel rolling, set suitable parameter, as the given signal of controller 2.Input signal is the fume emission monitor content of the atmospheric pollutant of monitoring continuously, feedback signal is output frequency, motor speed, the rotation speed of fan of frequency variator, controller is exported the proper frequency of frequency variator through computational analysis, thereby completes the rotating speed of automatic adjusting dedusting fan motor.
