For purpose of description, at first the roaster to routine briefly introduces.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 evacuation 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 regulate fuel duty, air inflow and the capacity that is fed to every quirk respectively by adjusting fuel control appliance, air intake apparatus or exhaust equipment.Therefore, can be to control or the combination control separately 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 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, is used for detecting the carbon monoxide content that gathers flue waste gas, 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 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, handle by 13 pairs of optical signals that received 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 online real-time detection carbon monoxide and export carbon monoxide content to control module 20 incessantly.In this exemplary, adopt a kind of mode in back to detect, that is, export the carbon monoxide content in the waste gas in real time.
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 first judge module 21 and first adjustment module 22.After receiving the carbon monoxide content value that Carbon Monoxide Detection module 10 sends, first judge module 21 judges according to carbon monoxide content, and first adjustment module 22 is carried out corresponding adjusting according to judged result to the burner of roaster.Specifically, can preestablish first threshold, by first judge module 21 carbon monoxide content and the first threshold that detection obtains be compared, first adjustment module 22 is according to the comparative result of 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, 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 down, the carbon monoxide content that is produced may be different.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 set different first thresholds according to different situations.For the convenience of handling, can in control device 20, memory cell be set, in order to store the pairing first threshold of various different situations respectively.Like this, after receiving the carbon monoxide content value of detection, first judge module 21 can call corresponding first threshold as the case may be and handle.Certainly, also can be after receiving the carbon monoxide content value of detection, in the artificial input of corresponding first threshold 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 pairing 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, first judge module 21 judges that whether the carbon monoxide content value is greater than presetting first threshold.First adjustment module 22 can be according to the judged result of first judge module 21, at carbon monoxide content during greater than presetting first threshold, generate fuel control appliance, air intake apparatus and the exhaust equipment instruction of one of them at least of control burner, thus fuel metering supply, air inflow and capacity at least one of them.As an example, when carbon monoxide content during, can reduce fuel duty or increase air inflow or increase capacity, so that fuel combustion is more abundant greater than first threshold; As another example, in order to reduce carbon monoxide content, can increase air inflow and capacity simultaneously 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 according to control command, make fuel control appliance, air intake apparatus and exhaust equipment can carry out corresponding adjusting respectively from master system.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 an air blast, and exhaust equipment can be the butterfly valve apparatus of smoke evacuation frame adjusted negative pressure.Certainly, also can use other to well known to a person skilled in the art that means realize fuel control appliance, air intake apparatus and the exhaust equipment of burner.
Though in theory, the carbon monoxide that burning generates is few more, and the expression combustion position is good more.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 helps saving production cost.Therefore, as long as carbon monoxide is not too high or low excessively, just can regulate burner.For this reason, the application has proposed a kind of optional embodiment, describes this exemplary with reference to Fig. 3 below, 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 first judge module 21, first adjustment module 22, the control module 20 ' of system 1 ' further comprises second judge module 24 and second adjustment module 25.Similar with the system 1 of Fig. 1, first judge module 21 compares carbon monoxide content and presetting first threshold, 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 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 first adjustment module 22 pairs of fuel duties, air inflow and capacities, carbon monoxide content may descend.When first judge module 21 judges that carbon monoxide content drops under the first threshold, can carbon monoxide content and second threshold value of presetting be compared by second judge module 24, second threshold value here for example can be lower limit or other default numerical value of carbon monoxide content, when the carbon monoxide content that is generated is between the first threshold and second threshold value, just needn't regulate the combustion position of roaster.Similar with first threshold, can pairing second threshold value of various different situations be set respectively according to the working of a furnace of roaster and the state of burner.One or more second threshold values can be stored in the memory cell of control module 20 ' in advance, also can manually be input to second judge module 24 when needed.
Next, if the judgment result displays of second judge module 24, carbon monoxide content is less than second threshold value, then fuel duty, air inflow and the capacity of regulating through first adjustment module 22 by 25 pairs of second adjustment modules one of them is further regulated at least.The situation that has reduced fuel duty with first adjustment module 22 is an example, and less than second threshold value, second adjustment module 25 can suitably increase fuel duty as if carbon monoxide content.Be appreciated that, the increase of 25 pairs of fuel duties of second adjustment module can be equal to or less than the reduction of 22 pairs of fuel duties of first adjustment module, in other words, second adjustment module 25 can return to fuel duty by first adjustment module 22 and regulate original state before, perhaps only fuel duty is partly recovered.When the fuel duty that the recovery of second adjustment module, 25 parts was regulated, can carry out repeatedly repetitive operation.For example, first adjustment module 22 has reduced Δ m with fuel duty, second adjustment module 25 can increase fuel duty 0.25 Δ m earlier, if the judged result of second judge module 24 remains carbon monoxide content less than second threshold value, then second adjustment module 25 can increase fuel duty 0.25 Δ m again.The further adjusting of 25 pairs of air inflows of second adjustment module, capacity is with similar to the further adjusting of fuel duty.In addition, under wherein two or three situations about overregulating of 22 pairs of fuel duties of first adjustment module, air inflow and three parameters of capacity, second adjustment module 25 can further be regulated at least one of the parameter of regulating.For example, if first adjustment module 22 has reduced fuel duty and increased air inflow and capacity simultaneously, then second adjustment module 25 can only increase fuel duty, perhaps only reduces air inflow, perhaps only reduces capacity; Second adjustment module 25 can also reduce air inflow or capacity when increasing fuel duty; Certainly, second adjustment module 25 also can not only reduce air inflow but also reduce capacity when increasing fuel duty.More than in the mode that exemplifies second adjustment module 25 has been described, those skilled in the art can easily expect, can 25 pairs of one of them further adjustings of carrying out at least through fuel duty, air inflow and the capacity of 22 adjustings of first adjustment module of 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 of describing in conjunction with Fig. 1 10, 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 bigger, and the bigger of air capacity and fuel duty in the quirk is described; Combustion coefficient is less, and the smaller of air capacity and fuel duty in the quirk is described.The combustion coefficient of each bar burning quirk that combustion coefficient computing module 130 will calculate offers control module 120.Though 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, can be provided with can the based on fuel control appliance and respectively the burn computing unit of combustion coefficient of quirk of the data computation that provides of air intake apparatus for control module 120.
In system 100 as shown in Figure 4, the combustion coefficient of each quirk that 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 burner.
Usually,, may represent that the burning in the stove is abundant inadequately, need to regulate combustion position if carbon monoxide content is higher in the roaster.But owing to have 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 the integral combustion situation in the roaster more targetedly.In view of this consideration, control module 120 shown in Figure 4 comprises first judge module 121, first adjustment module 122 and quirk setting module 123.Can preestablish first threshold, carbon monoxide content value and the first threshold that is detected be compared by first judge module 121.Here presetting first threshold can be similar with the first threshold that combines Fig. 1 description herein, here no longer to its detailed description.In addition, also predeterminable combustion coefficient threshold value, the combustion coefficient of each quirk that combustion coefficient computing module 130 is provided by quirk setting module 123 with should default combustion coefficient threshold, thereby determine which quirk need regulate.For example, can set the combustion coefficient threshold value like this: if the combustion coefficient of a quirk, represents then that the air capacity of this quirk is relative less with the ratio of fuel duty less than this combustion coefficient threshold value, burning may be abundant inadequately.At this moment, combustion coefficient can be set at the quirk of need adjusting less than the quirk of combustion coefficient threshold value.First adjustment module 122 is according to the judged result of 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 identical substantially with system shown in Figure 4 100, only describes the difference of the two below.As shown in Figure 5, the control module 120 ' of system 100 ' further comprises second judge module 124 and second adjustment module 125.After the carbon monoxide content that is detected is reduced under the carbon monoxide first threshold, judge further that by second judge module 124 whether carbon monoxide content is less than the second default threshold value.Here Yu She second threshold value can be similar with second threshold value that combines Fig. 3 description herein.Then, second adjustment module 125 can be at carbon monoxide content during less than second threshold value, fuel duty, air inflow and the capacity of the quirk that the need of regulating through first adjustment module 122 are regulated one of them is further regulated at least.Second adjustment module 25 in 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 first adjustment module is further regulated, its difference is, fuel duty, air inflow and/or the capacity of the quirk that 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 for example contactless Carbon Monoxide Detection device 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 detected greater than presetting first threshold, then in following step S30, fuel metering supply, air inflow and capacity at least one of them.Though 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, till carbon monoxide content is reduced 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 presetting 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 is detected then can increase air inflow and capacity still greater than first threshold.Be appreciated that concrete executive mode and can carry out different settings with the production demand as the case may be in proper order.
Referring to Fig. 7, its testing result that shows in step 20 shows that the carbon monoxide content that is detected is not more than the further operation of presetting 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 is detected is less than default second threshold value (step S40).If the carbon monoxide content that is detected is less than the second default threshold value, 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 carrying out S50, can regulate the different parameters in fuel duty, air inflow and three parameters of capacity respectively at every turn by setting in advance.For example, when after carrying out S40, judging carbon monoxide content, at first increase fuel duty, if carbon monoxide content reduces air inflow and capacity more still less than second threshold value less than second threshold value.
Fig. 8 shows the control method according to the roaster of 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, compare with presetting first threshold then.Method shown in Figure 8 also comprises combustion coefficient (step S600) that calculates each bar quirk and the step that combustion coefficient is set at the quirk (step S700) that needs adjusting less than the quirk of default combustion coefficient threshold value.In step S300, take all factors into consideration the execution result of step S200 and step S700 and further operate.Be appreciated that, step S600 and S700 can carry out after step S 100 and S200 carry out, also can carry out execution before with S200 by step S 100, 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, 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.Carrying out step S300, after the combustion position of roaster is regulated, reducing under the first threshold, further comparing carbon monoxide content and second threshold value (step S400) again if in step S200, judge carbon monoxide content.If the carbon monoxide content that detected is less than the second default threshold value, 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, in order to make carbon monoxide content reach suitable value, and can repeated execution of steps S400 and S900.
