The specific embodiment
For the purpose of describing, at first the roaster of routine briefly introduced.As everyone knows, roaster (for example, anode-baking furnace) can comprise a plurality of furnace chambers, and each furnace chamber can be provided with many quirks, and wherein, the number of furnace chamber and quirk can be by production capacity requirement design, and the furnace chamber number is generally 18 to 54, and the quirk number is generally 7 to 10.The burning of many quirk internal causes and the waste gas that generates are discharged into through the hose connector of roaster smoke discharge frame and gather in the flue, finally enter atmosphere after purifying.The burner of roaster is one of critical piece of roaster, can comprise burning rack, fuel control appliance, air intake apparatus and exhaust equipment that fuel can be burnt.Be appreciated that and by the adjusting to fuel control appliance, air intake apparatus or exhaust equipment, regulate respectively fuel duty, air inflow and the capacity that is fed to every quirk.Therefore, can be to separately control or the combination control of fuel control appliance, air intake apparatus and exhaust equipment, by, two or three parameters in fuel duty, air inflow and three parameters of capacity of regulating every quirk, thereby the ratio of fuel metering and air is to realize the control to the combustion position of roaster.
The content of the carbon monoxide that generates because of burning in the roaster can reflect the combustion position of roaster indirectly.Therefore, the disclosed system and method for the application as the parameter of determining combustion position, utilizes carbon monoxide content to come the combustion position of roaster is controlled the content of carbon monoxide.
Referring to Fig. 1, can comprise Carbon Monoxide Detection module 10 and control module 20 according to control system 1 the application's first aspect the first embodiment, that be used for roaster (for example anode-baking furnace).Carbon Monoxide Detection module 10 can be arranged on roaster and gather in the flue, for detection of the carbon monoxide content that gathers waste gas in the flue, and exports carbon monoxide content to control module 20.Control module 20 is carried out the data processing, generates and send control instruction, the roaster burner is controlled, and then the combustion position of control roaster.
Referring to Fig. 2, it shows a kind of carbon monoxide transducer 10 ' that can use as Carbon Monoxide Detection module 10 in system shown in Figure 1.As shown in Figure 2, carbon monoxide transducer 10 ' is a kind of contactless Carbon Monoxide Detection device.Specifically, shown carbon monoxide transducer 10 ' can comprise transmitting terminal 11, receiving terminal 12 and assessment unit 13.Transmitting terminal 11 and receiving terminal 12 can be installed in respectively on the relative the first side wall and the second sidewall that roaster gathers the flue outlet place.The transmitting terminal 11 of carbon monoxide transducer 10 ' sends light beam, and light beam is by being received by receiving terminal 12 after the waste gas.The optical signal that characterizes the light beam of receiving terminal 12 receptions can be by default CAN (Controller Area Network, controller area network) bus sends assessment unit 13 to, processed by 13 pairs of optical signals that receive of assessment unit, thereby obtain carbon monoxide content value in the waste gas.
Be appreciated that, use carbon monoxide transducer 10 ' shown in Figure 2, can regularly detect carbon monoxide and export carbon monoxide content to control module 20, also can detect in real time online carbon monoxide and export incessantly carbon monoxide content to control module 20.In this exemplary, a kind of mode detects after adopting, and, exports in real time the carbon monoxide content in the waste gas that is.
Get back to Fig. 1, control module 20 receives the carbon monoxide content value of Carbon Monoxide Detection module 10 outputs, and carries out respective handling.In a kind of exemplary, control module 20 can be arranged on the software module in the middle control management level master system of roaster.As a kind of optional mode, also control module 20 can be set to be independent of the independent mechanism of master system.In addition, it will be appreciated by those skilled in the art that Carbon Monoxide Detection module 10 in several ways (for example wired mode or wireless mode) the carbon monoxide content value that detects is sent to control module 20.
As shown in Figure 1, control module 20 can further comprise the first judge module 21 and the first adjustment module 22.After receiving the carbon monoxide content value that Carbon Monoxide Detection module 10 sends, the first judge module 21 judges according to carbon monoxide content, and the first adjustment module 22 is carried out corresponding adjusting according to judged result to the burner of roaster.Specifically, can preset first threshold, by the first judge module 21 carbon monoxide content and the first threshold that detection obtains be compared, the first adjustment module 22 is according to the comparative result of the first judge module 21, send corresponding control instruction, thereby the combustion position of roaster is regulated.
It will be understood by those skilled in the art that in roaster, the part in many quirks can be burnt in turn, and for this reason, burner can be shifted one's position in roaster.For example, in different roasters, because such as the difference of the working of a furnace of furnace chamber size, furnace chamber number, quirk number etc., even combustion position is identical lower, the carbon monoxide content that produces may difference.In addition, in the identical roaster of the same race of the working of a furnace, since the burner state, the different carbon monoxide that identical combustion position also may generate.Here said burner state for example can be, burner is arranged in different furnace chambers, or is under the state of turning round or the linear state.Like this, can according to different situations, set different first thresholds.For the convenience of processing, can in control device 20, memory cell be set, in order to store respectively the corresponding first threshold of various different situations.Like this, after receiving the carbon monoxide content value of detection, the first judge module 21 can call as the case may be corresponding first threshold and process.Certainly, also can be after receiving the carbon monoxide content value of detection, in the artificial input of corresponding first threshold the first judge module 21.
In a specific embodiment, first threshold can be the higher limit of the carbon monoxide content determined according to the working of a furnace and burner state.Certainly, first threshold can also be that corresponding combustion position was more satisfactory when carbon monoxide content was lower than first threshold according to the different working of a furnaces and other definite numerical value of burner situation.In this embodiment, the first judge module 21 judges that whether the carbon monoxide content value is greater than default first threshold.The first adjustment module 22 can be according to the judged result of the first judge module 21, at carbon monoxide content during greater than default first threshold, generate at least instruction of one of them of fuel control appliance, air intake apparatus and exhaust equipment of control combustion device, thus fuel metering supply, air inflow and capacity at least one of them.As an example, when carbon monoxide content during greater than first threshold, can reduce fuel duty or increase air inflow or increase capacity, so that fuel combustion is more abundant; As another example, in order to reduce carbon monoxide content, can increase simultaneously air inflow and capacity or when reducing fuel duty, increase air inflow or when reducing fuel duty, increase capacity, can also when reducing fuel duty, not only increase air inflow but also increase capacity.
Be appreciated that, in roaster, fuel control appliance, air intake apparatus and the exhaust equipment of burner (for example can be respectively arranged with corresponding controlling organization, can be programmable logic controller (PLC)), with the control command of basis from master system, respectively so that fuel control appliance, air intake apparatus and exhaust equipment can carry out corresponding adjusting.Certainly, the controlling organization of fuel control appliance, air intake apparatus and exhaust equipment also can integrate, and the concrete set-up mode of controlling organization is that those skilled in the art can expect, is not described in detail here.The corresponding controlling organization that the instruction that control module 20 generates sends to the equipment that will control carries out concrete operations, thus fuel metering supply, air inflow and/or capacity.As a kind of exemplary embodiment, the fuel control appliance can be the fuel flow rate adjusting device on the burning rack, and air intake apparatus can be air blast, and exhaust equipment can be the butterfly valve apparatus of smoke discharge frame adjusted negative pressure.Certainly, also can well known to a person skilled in the art that means realize fuel control appliance, air intake apparatus and the exhaust equipment of burner with other.
Although in theory, the carbon monoxide that burning generates is fewer, and the expression combustion position is better.But, it will be appreciated by those skilled in the art that in the production of reality, will carbon monoxide content do not drop to too lowly, but hold it in the acceptable number range, this is conducive to save production cost.Therefore, as long as carbon monoxide is not too high or excessively low, just can regulate burner.For this reason, the application has proposed a kind of optional embodiment, and the below describes this exemplary with reference to Fig. 3, and is concise and to the point for what describe, mainly describes the difference of system shown in Figure 31 ' and system 1 shown in Figure 1.
As shown in Figure 3, except the first judge module 21, the first adjustment module 22, the control module 20 ' of system 1 ' further comprises the second judge module 24 and the second adjustment module 25.Similar with the system 1 of Fig. 1, the first judge module 21 compares carbon monoxide content and the first threshold of presetting, and first threshold herein is identical with the implication of the first threshold of describing with reference to Fig. 1.At this moment, if carbon monoxide content greater than first threshold, then the first adjustment module 22 fuel metering supplys, air inflow and capacity at least one of them.After one of them is regulated at least of the first adjustment module 22 pairs of fuel duties, air inflow and capacities, carbon monoxide content may descend.When the first judge module 21 judges that carbon monoxide content drops under the first threshold, can carbon monoxide content and the Second Threshold of presetting be compared by the second judge module 24, the Second Threshold here for example can be lower limit or other default numerical value of carbon monoxide content, when the carbon monoxide content that generates is between first threshold and Second Threshold, just needn't regulate the combustion position of roaster.Similar with first threshold, can according to the working of a furnace of roaster and the state of burner, the corresponding Second Threshold of various different situations be set respectively.One or more Second Thresholds can be pre-stored in the memory cell of control module 20 ', also can manually be input to when needed the second judge module 24.
Next, if the judgment result displays of the second judge module 24, carbon monoxide content is less than Second Threshold, fuel duty, air inflow and the capacity of then being regulated through the first adjustment module 22 by 25 pairs of the second adjustment modules one of them is further regulated at least.The situation that has reduced fuel duty take the first adjustment module 22 is as example, if carbon monoxide content less than Second Threshold, the second adjustment module 25 can suitably increase fuel duty.Be appreciated that, the increase of 25 pairs of fuel duties of the second adjustment module can be equal to or less than the reduction of 22 pairs of fuel duties of the first adjustment module, in other words, the second adjustment module 25 can return to fuel duty by the first adjustment module 22 and regulate original state before, perhaps only fuel duty is partly recovered.When the fuel duty that the recovery of the second adjustment module 25 parts was regulated, can carry out repeatedly repetitive operation.For example, the first adjustment module 22 has reduced Δ m with fuel duty, the second adjustment module 25 can increase fuel duty first 0.25 Δ m, if the judged result of the second judge module 24 remains carbon monoxide content less than Second Threshold, then the second adjustment module 25 can increase fuel duty 0.25 Δ m again.The further adjusting of 25 pairs of air inflows of the second adjustment module, capacity is with similar to the further adjusting of fuel duty.In addition, in wherein two or three situations about overregulating of 22 pairs of fuel duties of the first adjustment module, air inflow and three parameters of capacity, the second adjustment module 25 can further be regulated at least one of the parameter of regulating.For example, if the first adjustment module 22 has reduced fuel duty and increased simultaneously air inflow and capacity, then the second adjustment module 25 can only increase fuel duty, perhaps only reduces air inflow, perhaps only reduces capacity; The second adjustment module 25 can also reduce air inflow or capacity when increasing fuel duty; Certainly, the second adjustment module 25 also can not only reduce air inflow but also reduce capacity when increasing fuel duty.Abovely in the mode that exemplifies the second adjustment module 25 has been described, those skilled in the art can easily expect, can 25 pairs of at least one of them further adjustings of carrying out through fuel duty, air inflow and the capacity of 22 adjustings of the first adjustment module of the second adjustment module be set according to specific requirement.
Below with reference to second embodiment of Fig. 4 detailed description according to the application's first aspect.As shown in Figure 4, the control system 100 of roaster comprises Carbon Monoxide Detection module 110, control module 120 and combustion coefficient computing module 130, wherein, Carbon Monoxide Detection module 110 can adopt identical structure and configuration with the Carbon Monoxide Detection module 10 of describing in conjunction with Fig. 1, therefore is not described in detail.Shown in system 100 in, combustion coefficient computing module 130 calculates the combustion coefficient of each bars burning quirk.In this application, combustion coefficient refers to the ratio of air capacity and fuel duty in the specific quirk.In the disclosed embodiment of the application, combustion coefficient computing module 130 can obtain being fed to a fuel duty in the quirk according to the fuel control appliance of burner, and the air capacity that obtains entering this quirk according to the air intake apparatus of burner, calculate the ratio of air capacity and fuel duty, thereby obtain the combustion coefficient of this quirk.Combustion coefficient can be used as one of parameter of each quirk internal combustion situation of quantitatively characterizing, and combustion coefficient is larger, and the larger of quirk hollow tolerance and fuel duty is described; Combustion coefficient is less, and the smaller of quirk hollow tolerance and fuel duty is described.The combustion coefficient of each bar burning quirk that combustion coefficient computing module 130 will calculate offers control module 120.Although in system shown in Figure 4 100, combustion coefficient computing module 130 is standalone modules of control module 120 outsides, but be appreciated that, combustion coefficient computing module 130 also can be arranged on the inside of control module 120, in other words, control module 120 can be provided with can the based on fuel control appliance and the data that provide of air intake apparatus calculate the computing unit of the combustion coefficient of the quirk that respectively burns.
In system 100 as shown in Figure 4, the combustion coefficient of each quirk that the carbon monoxide content value that control module 120 can provide according to Carbon Monoxide Detection module 110 and combustion coefficient computing module 130 provide, take carbon monoxide content value and combustion coefficient value into consideration, generate the instruction of control combustion device.
Usually, if carbon monoxide content is higher in the roaster, may represent that the burning in the stove is abundant not, need to regulate combustion position.But owing to having many burning fire roads, the combustion position of every quirk may be not quite similar.At this moment, if only the relatively poor quirk of those combustion positions is regulated, can improve more targetedly the integral combustion situation in the roaster.In view of this consideration, control module 120 shown in Figure 4 comprises the first judge module 121, the first adjustment module 122 and quirk setting module 123.Can preset first threshold, by the first judge module 121 carbon monoxide content value and the first threshold that detects be compared.Here default first threshold can with to be combined the first threshold that Fig. 1 describes herein similar, here no longer to its detailed description.In addition, predeterminable combustion coefficient threshold value also, the combustion coefficient of each quirk that combustion coefficient computing module 130 is provided by quirk setting module 123 and combustion coefficient threshold that should be default, thus determine which quirk need regulate.For example, can set like this combustion coefficient threshold value: if the combustion coefficient of a quirk, then represents the ratio less of air capacity with the fuel duty of this quirk less than this combustion coefficient threshold value, burning may be abundant not.At this moment, combustion coefficient can be set as the quirk of need adjusting less than the quirk of combustion coefficient threshold value.The first adjustment module 122 is according to the judged result of the first judge module 121, at carbon monoxide content during greater than first threshold, to carrying out corresponding adjusting by the determined combustion positions of the quirks regulated that need of quirk setting module 123.
Be appreciated that adjusting that the combustion position of the quirk that need are regulated carries out can be regulate fuel control appliance, air intake apparatus and the exhaust equipment of these quirks at least one of them, thereby fuel metering supply, air inflow and capacity at least one of them.
Fig. 5 shows a kind of modification of control system shown in Figure 4.System 100 ' shown in Figure 5 is substantially identical with system shown in Figure 4 100, and the below only describes the difference of the two.As shown in Figure 5, the control module 120 ' of system 100 ' further comprises the second judge module 124 and the second adjustment module 125.After the carbon monoxide content that detects is reduced under the carbon monoxide first threshold, judge further that by the second judge module 124 whether carbon monoxide content is less than default Second Threshold.Here default Second Threshold can with to be combined the Second Threshold that Fig. 3 describes herein similar.Then, the second adjustment module 125 can be at carbon monoxide content during less than Second Threshold, fuel duty, air inflow and the capacity of the quirk that the need of regulating through the first adjustment module 122 are regulated one of them is further regulated at least.The second adjustment module 25 in the second adjustment module 125 shown in Figure 5 and the system 1 ' shown in Figure 3 is similar, also be that the parameter of being regulated by the first adjustment module is further regulated, its difference is, fuel duty, air inflow and/or the capacity of the quirk that the second adjustment module 125 among Fig. 5 is only regulated the need of being determined by quirk setting module 123 are regulated.
Below with reference to Fig. 6～8, the control method according to the roaster of the application's second aspect is described.
As shown in Figure 6, at first in step S10, can adopt contactless Carbon Monoxide Detection device for example to detect the carbon monoxide content that gathers waste gas in the flue of roaster.If the judged result of step S20 be the carbon monoxide content that detects greater than default first threshold, then in following step S30, fuel metering supply, air inflow and capacity at least one of them.Although clearly do not illustrate among the figure, but it will be understood by those skilled in the art that repeated execution of steps S20 and S30, until till carbon monoxide content is down under the first threshold.In addition, in the process of repeated execution of steps S20 and S30, judge at every turn carbon monoxide content greater than default first threshold after, can regulate the different parameters in fuel duty, air inflow and three parameters of capacity.For example, after reducing fuel duty, if the carbon monoxide content that detects still greater than first threshold, then can increase air inflow and capacity.Be appreciated that concrete executive mode and sequentially can carry out different settings with Production requirement as the case may be.
Referring to Fig. 7, its testing result that shows in step 20 shows that the carbon monoxide content that detects is not more than the further operation of default first threshold.After carrying out step S30, fuel duty, air inflow and capacity one of them has passed through adjusting at least, the carbon monoxide content in the roaster may descend.After carbon monoxide content drops under the first threshold, judge that further whether the carbon monoxide content that detects is less than default Second Threshold (step S40).If the carbon monoxide content that detects is less than default Second Threshold, then to fuel duty, air inflow and the capacity of adjusted mistake in step S30 one of them further regulates (step S50) at least, for example, the fuel duty, air inflow and/or the capacity that were conditioned are operated by one or many, recover or the part recovery with respect to the initial value before regulating.Be appreciated that step S40 and S50 also can repeat, and when each execution S50, can regulate the different parameters in fuel duty, air inflow and three parameters of capacity respectively by setting in advance.For example, when after carrying out S40, judging carbon monoxide content less than Second Threshold, at first increase fuel duty, if carbon monoxide content still less than Second Threshold, reduces air inflow and capacity again.
Fig. 8 shows the control method according to the roaster of the second embodiment of the application's second aspect.Step S10 and S20 shown in step S100 in the method shown in Figure 8 and S200 and Fig. 6 and 7 in the method are similar, all are the carbon monoxide contents that gathers waste gas in the flue that detects roaster, then compare with the first threshold of presetting.Method shown in Figure 8 also comprises the combustion coefficient (step S600) that calculates each bar quirk and the step that combustion coefficient is set as the quirk (step S700) that needs adjusting less than the quirk of default combustion coefficient threshold value.In step S300, the execution result that considers step S200 and step S700 further operates.Be appreciated that, step S600 and S700 can carry out after step S100 and S200 execution, also can step S100 and S200 carry out before carrying out, can certainly carry out together, as long as when step S300 carries out, can access the execution result of step S200 and step S700.When the result of step S200 shows carbon monoxide content greater than first threshold, then in step S300, fuel duty, air inflow and the capacity of the quirk that the need of being set by step S700 are regulated one of them is regulated at least.The method of describing with reference Fig. 6 is similar, but repeated execution of steps S200 and S300, until till carbon monoxide content drops under the first threshold.
Here said combustion coefficient is identical with the combustion coefficient implication of describing according to the application's first aspect before, repeats no more herein.
Fig. 9 is the modification to method shown in Figure 8.Carry out step S300, after the combustion position of roaster is regulated, be down under the first threshold if in step S200, judge carbon monoxide content, further comparing again carbon monoxide content and Second Threshold (step S400).If the carbon monoxide content that detects is less than default Second Threshold, execution in step S900 then, fuel duty, air inflow and the capacity of the quirk that need adjusted in step S300 are regulated one of them is further regulated at least.The method of describing with reference Fig. 7 is similar, for so that carbon monoxide content reaches suitable value, and can repeated execution of steps S400 and S900.
