Specific embodiment
Purport of the present utility model is to overcome the deficiencies in the prior art, there is provided a kind of klin pressure control system of glass furnace,
Can more efficient stable control furnace pressure.
It is described in detail referring to the drawings with reference to embodiment, to enter to technical characteristic of the present utility model and advantage
Row deeper into annotation.
Flow chart of the present utility model as shown in Figure 1, the klin pressure control system of a kind of glass furnace 1, including pipeline is successively
Glass furnace 1, main chimney flue 2, primary pressure sensor 31, adjuster, controller 5, air-introduced machine 6 and the chimney 7 being linked in sequence, also wraps
Secondary stress sensor 32 is included, described adjuster includes master selector 41 and secondary controller 42, is provided with described glass furnace 1
Melting end 8, described one end of secondary stress sensor 32 connects with melting end 8, and the other end is connected with secondary controller 42.Main chimney flue 2
Pressure sends the input of the master selector 41 of control loop to by primary pressure sensor 31, and given with master selector 41
Value is done and the given of secondary controller 42 is given after deviation control, and the pressure feedback regulation mode of main chimney flue 2 is adjusted；While glass furnace 1
The pressure of interior melting end 8 is sent to secondary controller 42 as feed-forward signal by secondary stress sensor 32, finally has by secondary controller
Feed-forward signal is superimposed output with feedback signal by 42 is sent to controller 5, and the rotating speed that controller 5 passes through regulation air-introduced machine 6, change is right
The draft of flue, controls discharge rate of the flue gas by chimney 7, so as to adjust the pressure of the melting end 8 of main chimney flue 2 and the stove of glass furnace 1
Power.Additionally, the pressure samples point of melting end 8 is distant with the pressure samples point of main chimney flue 2, the pressure of melting end 8 is occurred in that

The average pressure of pressure, described secondary stress sensor 32 is sent to the pressure of the input of secondary controller 42 in melting end 8 three
The average pressure of individual pressure, because different parts flue gas pressures value is also different on main chimney flue 2, same melting end 8 is different
Site pressure is also incomplete same, take three point pressures then it is average after it is more accurate as input pressure value, adjust result more
Meet reaction desirable pressure, four can also be taken here certainly and press that force value is average or pressure values of more than five points are average.
For accurate adjustment pressure, described master selector 41 is PID regulator, described control with secondary controller 42
Device 5 is the frequency converter of air-introduced machine 6, the draft of the rotational speed regulation blower fan by changing the frequency shift blower fan of air-introduced machine 6, stabilized glass kiln
Pressure in 1 stove.
In the utility model, pressure is connected with main chimney flue by pipeline and produces impact to pressure in main chimney flue in melting end,
Pressure belongs to the factor of main interference main chimney flue pressure in melting end, takes putting down for the multiple pressure parameters in glass furnace melting end
It is sent in secondary PID regulator by the output of secondary stress sensor as pressure signal, secondary PID regulator is carried out to main interference
Feedforward control；Take multiple pressure parameters in main chimney flue as mean value output be sent to main PID regulator input and with master
The set-point of PID regulator does gives the given of secondary PID regulator after deviation control, secondary PID regulator does feedback to deviation and adjusts
Section；Feed-forward regulation is superimposed with feedback regulation air-introduced machine frequency converter is adjusted by secondary PID regulator, changes the rotating speed of air-introduced machine,
Draw change blower fan to the draft inside flue so as to change, it is ensured that the pressure zero-pressure or pressure-fired in glass furnace.The pressure of melting end
Power sample point is distant with the pressure samples of main chimney flue point, and the pressure of melting end occurs in that fluctuation, and the pressure of main chimney flue differs
