Description
The present invention relates to the oxygen concentration in the combustion apparatus waste gas is controlled at the burning and gas-exhausting oxygen concentration control device of given range with interior combustion apparatus being used for burning the stove that municipal refuse or industrial waste use.
Figure 20 is the topology example figure of oxygen concentration control device in the burning and gas-exhausting of existing this type of combustion apparatus of expression.In Figure 20, the 7th, incinerator, in this incinerator 7, primary air supplies to the bottom from primary air feeder 5, and auxiliary air (combustion air) supplies to free space.The 8th, send into the comburant feeding hopper of comburants such as municipal refuse or industrial waste, the 9th, with the comburant drawing-in device from the comburant feeding incinerator 7 of this comburant feeding hopper feeding.
The 1st, the density of oxygen contained in discharged gas test side, the 2nd, the density of oxygen contained in discharged gas detecting sensor, by this density of oxygen contained in discharged gas test side 1 and density of oxygen contained in discharged gas detecting sensor 2, detect the oxygen concentration in the burning and gas-exhausting, and be transported in the density of oxygen contained in discharged gas adjuster 3 with the form of detection signal PV1.In this density of oxygen contained in discharged gas adjuster 3, by PID(ratio, integration, differential) arithmetic unit, deviation between the setting value SV1 of above-mentioned detection signal PV1 and density of oxygen contained in discharged gas adjuster 3 is carried out computing, and output control output signal MV1, the air door of feeding secondary air is regulated.
Consequently: need certain hour because exhaust flows to the test point of density of oxygen contained in discharged gas; And the reason of classes such as detection hysteresis of density of oxygen contained in discharged gas detecting sensor, though oxygen concentration on average can be remained in the given range, temporary transient not enough or superfluous phenomenon tends to produce oxygen.
Figure 21 is the special structure chart of being willing to the burning and gas-exhausting oxygen concentration control device that proposes in order to improve above-mentioned shortcoming for clear 63-155631 number of expression.The burning and gas-exhausting oxygen concentration control device among Figure 21 and the difference of the burning and gas-exhausting oxygen concentration control device among Figure 20 are: be provided with brightness test side 10 and brightness detecting sensor 11, by this brightness test side 10 and brightness detecting sensor 11, detect the interior fiery scorching brightness of stove of incinerator 7, and flow to the nonlinear operation device 12 that possesses characteristic shown in Figure 22 with the form of detection signal PV2, export the control signal Y1 of the auxiliary air air feed air door 4 of brightness detecting sensors 11 generations by this nonlinear operation device 12, and be transported in the adder calculator 13.
Then in adder calculator 13, the signal according to transporting from density of oxygen contained in discharged gas adjuster 3 and nonlinear operation device 12 carries out following computing, regulates auxiliary air air feed air door 4 then.
Y2＝K1×MV1+K2×Y1
K1K2 is a constant in the formula.
Because oxygen concentration control device has adopted structure shown in Figure 21 in the burning and gas-exhausting, the result is that exhaust flows to the time of density of oxygen contained in discharged gas test point and the shortcomings such as hysteresis of detecting sensor are significantly improved.But, because temperature, the character of rubbish, the water capacity in the exhaust in the stove of incinerator 7, and the difference of the pollution level on brightness detecting sensor surface etc., the signal of brightness detecting sensor is changed, when quantity combusted is big, will draw the high result of density of oxygen contained in discharged gas, through stable can cause cold; When quantity combusted hour, it is temporarily not enough to draw air, and the control output from oxygen concentration adjuster 3 is raise, so stop the quantity delivered air supply by at ordinary times, the result caused cold, thereby the shortcoming of CO occurred generating.
In addition, be willing in flat 1-212824 number (spy opens flat 3-75402 communique) the spy, the method of control burning is to make the primary air shunting of supplying with the siege bottom, basically control the auxiliary air amount of supplying with to free space (shunting air capacity) according to the output of brightness detecting sensor, and compensate this brightness detecting sensor over time according to the output of oxygen concentration adjuster.In burning and gas-exhausting oxygen concentration control method, when adopting the method for controlling combustion of said structure, above-mentioned drawback can obtain improvement to a certain degree.
But for example in the Boiling Combustion stove, when fluidizing air reduced, the siege temperature reduced, and caloric value increases, and sand face height (sand level) reduces to wait all will become the key factor that the fired state in the stove is produced various influences, as shown in figure 23.The reduction of fluidizing air amount and siege temperature can cause the gasification of comburant slow, and the furnace pressure change slowly can cause the extraction flow change to reduce.In addition, the reduction of siege temperature, the reduction of the increase of caloric value and sand face height, the meeting layer causes the decline of combustion rate in the sand.The decline of combustion rate in the sand, burning in the free space is increased, flame brightness increases, top temperature rises, the result causes free space furnace wall red heat, so the image processing signal of output that detects the flame sensor (brightness detecting sensor) of brightness in the stove and the ITV that monitors the fired state in the stove is increased.
Moreover as shown in figure 24, the increase of siege water injection rate can cause the reduction of siege temperature; The reduction of siege temperature can cause furnace pressure to change slowly again.In addition, the increase of the increase of siege water injection rate and furnace roof injection flow rate can cause the increase of exhaust water capacity; The increase of exhaust water capacity can cause oxygen concentration decline in the stove, flame brightness decline and extraction flow increase.And the flame lowering of luminance can cause the output of flame sensor (detecting sensor) to descend again, and the image processing signal of ITV descends.
As mentioned above, a lot of to the influential factor of stove internal combustion state, the output that is used for grasping the stove internal combustion state detection sensors such as brightness detecting sensor, ITV of the fired state in the stove also is subjected to the influence of these factors and change to some extent.Therefore, basically utilize the output signal of fired state detecting sensor to control density of oxygen contained in discharged gas, only export by the control of oxygen concentration adjuster, compensate this fired state detecting sensor over time the time, the problem of existence is the control method that can not get the good burning and gas-exhausting oxygen concentration of precision height and stability.

Y3＝K1×MV1×PV2×Y23
Even the output of the brightness detecting sensor 11 of brightness increases in the detection stove, its reason also has many kinds of situations.In the Boiling Combustion stove, as shown in figure 23, the temperature of siege descends, can cause length → flame brightness increase on the combustion rate decline → unpolarized burning rate in the sand, therefore, even the output of brightness detecting sensor 11 increases, its reason also has two kinds, a kind of is because quantity combusted increases the occasion of the flame brightness increase that causes, another kind is that quantity combusted is identical, but because the siege temperature descends, causes that combustion rate descends in the sand, the result increases the combustion rate of free space, thus the occasion that flame brightness increases.
Therefore in present embodiment 1, as shown in figure 11, when the output PV3 of siege temperature detection sensor 22 hangs down,, output Y23 is descended through in siege temperature-compensating arithmetic unit 23, carrying out computing; When the output PV3 of siege temperature detection sensor 22 is high, output Y23 is raise, this output Y23 is imported in the above-mentioned compensation operation device 14.Therefore, utilize the control output signal MV1 of density of oxygen contained in discharged gas adjuster 3, the brightness detecting sensor 11 of compensation stove internal combustion state detection sensor over time, meanwhile, utilize again the influential siege temperature of the output of this brightness detecting sensor 11 is compensated, therefore it is higher to reach precision, the burning and gas-exhausting oxygen concentration control of good stability.

Y3＝K1×MV1×PV2×Y29
As mentioned above, descend even detect the output of the brightness detecting sensor 11 of brightness in the stove, its reason also has many kinds of situations.In the Boiling Combustion stove, as shown in figure 24, the increase of siege water injection rate, tend to cause the output of exhaust water capacity increase → flame brightness deterioration → brightness detecting sensor (flame sensor) to descend, so even the output of brightness detecting sensor 11 descends, following two kinds of situations are at least also arranged, a kind of is the occasion of the flame brightness deterioration that causes of the minimizing owing to quantity combusted, another kind is that quantity combusted is identical, but as mentioned above, cause the flame brightness deterioration owing to the siege water injection rate increases, cause the occasion of the output decline of brightness detecting sensor.
Therefore in present embodiment 3, as shown in figure 13, when the output PV5 of siege water injection rate detecting sensor 28 hangs down, in siege water injection rate compensation operation device 29, carry out computing, cause output Y29 to reduce; When the output PV5 of siege water injection rate detecting sensor 28 is high, output Y29 is increased.This output Y29 is imported in the above-mentioned compensation operation device 14.Therefore utilize the control output signal MV1 of density of oxygen contained in discharged gas adjuster 3, brightness detecting sensor 11 to stove internal combustion state detection sensor compensates over time, also utilize simultaneously the influential siege water injection rate of the output of this brightness detecting sensor 11 is compensated, just can reach the burnt gas oxygen concentration control of more accurate good stability.
