Description

200900153 IX. Description of the Invention: [Technical Field] The present invention relates to a method of controlling dust emission from an electrostatic precipitator having a final field, the last field providing a discharge electrode and a collecting electrode And a slap device adapted to smear the collector electrodes by slap them. The invention also relates to a method of predicting the emission of dust particles during the slap of at least one of the collection electrodes of the last field of the electrostatic precipitator.

The invention also relates to a control system for controlling the emission of dust particles from an electrostatic precipitator of the type described above. The invention also relates to a control system for predicting the emission of dust particles from an electrostatic precipitator of the type described above. [Prior Art] Combustion of media, oil, industrial waste, household waste, peat, organisms, etc. produces flue gas containing dust particles (often referred to as fly ash ρ dust particles must be kept in the emission of ambient air - Low level, due to &, the emission of flue gas to the air of the '% of the air' often uses a type of electrostatic precipitator (10) p) filter to collect dust particles from the flue gas. In other documents, the Esp system, which is still known from 4, 5, 2, 872, provides a discharge electrode and a collector electrode plate. The discharge electrode collects the dust particles at the collecting electrode plate after the discharge electrode charges the dust particles. When the collecting electrode plates are loaded with dust particles, the collecting electrode plates are slapped so that the collected dust particles are released from the collecting electrode plates and dropped into the funnel from which the dust particles can be transported. The dust-removed gas is emitted via the stacking (4) air. 129145.doc 200900153 ESP often provides several serial-integrated units, also known as fields. An example of this can be found in WO 9!, ed. 37, which describes an individual field of three series of light combinations. The first field + θ ^ collects a large number of dust particles, so it requires a much more frequent slap than the subsequent field. It is said that the latter is only about 0 to 3 〇 / 〇 of the total amount of dust particles entering the ESP. When the slap (1 line is based on the pre-authorization rule), the number of granules leaving the ESP and emitted to the ambient air brother hole is increased to a relatively high position during a short period of time. + i Drought particles in the flue gas are even visually observed when they are emitted via stacking. < SUMMARY OF THE INVENTION The present invention is directed to providing a method for controlling a temporary large dust particle emission peak caused by a last field slap in an electrostatic precipitator. A method of controlling dust emission from an electrostatic precipitator having a final field, the last field providing a discharge electrode, a collecting electrode, and a slap device, the slap device being adapted To remove dust by slapping the collecting electrodes, the method is characterized as the following steps: i) using one of the selected dust particles to be selected by a selected slap, and the selected slap a relationship between one time immediately before the previous slap, and ii) based on the relationship, adjusting at least one parameter selected from the group consisting of: the time of the last time before the slap is performed in the last field, And the type of slap to be performed in the final game. One of the advantages of this method is that it can not exceed the dust emission limit of this method 129145.doc 200900153 accurately control the slap. Thus, by the present invention, fewer fields, or smaller fields, can be employed in an electrostatic precipitator (as compared to the fields necessary to operate in accordance with prior art methods). This is because, in accordance with an embodiment of the present invention, the method of operating the electrostatic precipitator reduces the mechanics of the electrostatic precipitator. also. The fact that the tenth king of the king is limited. The control of the slap may be related to the time of the slap before the slap is to be performed, or may be related to the type of slap to be performed, or may be related to both the time of the slap and the type of slap. According to a specific embodiment, the step (1) further includes calculating a rolling average value corresponding to an average dust emission during a predetermined period, and based on the relationship, relative to a predetermined fluctuation average limit value. The slap of the collection electrodes of the last field is adjusted. This particular embodiment is advantageously provided to not exceed the dust particle emission limit due to inadvertent (4) inadvertent time, or inadvertently performing the wrong slap type (the restriction system - the wave mode control slap. For example, in the step 〇, the type of the desired type is identified, and the type-specific model is selected to be used in step i} to use the type of the selected slap type H 1 feature model by selecting the slap Cause = the peak of the emission of the dust particles - the magnitude of the relationship between the selected type of slap slaps and the type of the slap. The type of relationship between the time of the beat / slap... the dust released during the month The amount depends on the slap performed, and the slap is a specific model of the slap type, which can be controlled by real expansion. 』%%-more preferably, in shai step i) Identifying and considering the relationship between the peak of the dust emission of 129145.doc 200900153 and the time between the selected slap and the first slap. Previously executed slap The slap of the immediately preceding; has to be identified. The amount of dust released during a slap depends on the type of slap that was taken before the slap. It can be implemented - more accurately controlled by considering the type of slap performed prior to the slap.

The longer the time since the previous shot was taken, the more dust is released during the slap. However, 'dust will also stick to the collecting electrode plate, so the 戎 relationship between the peak of the selected dust emission peak and the time since the previous slap is non-linear' is the best. Described by a one-to-one function 0. According to the specific embodiment of the car father, one of the selected values of the selected value by one selected slap is between one of the selected (4) and the immediately preceding = A mathematical model of the relationship can be obtained by measuring the magnitude of the peak of the dust particle and making it coincide with the individual time of the individual since the previous slap. ...Beibei (4) can be used to make the update by the following steps - one of the selected slaps is selected 129145.doc 200900153 to determine the peak of the dust emission - the amplitude and the selected slap immediately before it a mathematical model of the relationship between the times of the hits D) measuring the dust emission after the last field to identify a dust emission peak associated with one of the at least one collecting electrode of the last field, E) The measured amplitude of the dust mite emission peak is lighted from the corresponding time of the at least-collecting electrode of the last field since the previous slap to form a data record.

The amplitude of the peak of the dust emission caused by the slap of the electrode, the target value of the measured emission peak amplitude of the peak of the emission of the wire will be compared with the calculation device of the dust particle emission peak, and The dusting pull is used to minimize the target value of the peak amplitude of the dust particle emission and the subsequent slap by one of the collecting electrodes of the collecting electrodes: the difference between the measured amplitudes of the peaks of the dust particle emission Purpose, by means of the meter: the device 'automatically adjusts at least from the following group' parameters: the time of the last time before the last field is to be executed, and the subsequent type of slap to be performed in the last field. The advantages of this embodiment are: a relatively simple computing device, such as a PID controller, a ρι controller or a modelless adaptive controller. Since there is no need for a model, there is no need for any extensive work related to obtaining this model. In addition, the control of the slap will be adapted relatively quickly to suit the changing conditions of the electrostatic precipitator since the measurement data relating to the magnitude of the peak of the dust emission is continuously transmitted to the computing device. Another object of the present invention is to provide a reliable method for predicting the emission of dust particles during the slap of at least one of the collection electrodes of the last field of the electrostatic precipitator.

Therefore, it is possible to pre-slap the frequency, which dust particle is emitted by the sheep, or predict which fluctuation average is needed. This dust particle emission, for example, during the most useful phase of a dust particle emission: can be used in the design of an electrostatic precipitator, and in the adjustment of the operation of the device of the present invention. In addition to, or at least reducing, the purpose of providing a control system that allows for the occurrence of temporary dust particles to be generated during the final slap of the dust collector.

The advantage of this control system is that it provides effective control of the slamming, so that dust emission from the electrostatic precipitator can be minimized. According to a preferred embodiment, the control system further includes a bead receiver operative to receive measurement data relating to the dust T emission after the last field, and at the end of the measurement data identification and At least the collector-related dust-collecting peak of the collecting electrode, a data processing n, which is operable to record the at least one collecting electrode of the last field from the first two strikes The corresponding time is lightly combined to form a data record comprising the amplitude of the peak and the corresponding time since the previous slap, and the computing device is operable Based on the data record, the mathematical model is updated.

In the art, as is well known in the art, for example, from U.S. Patent No. 4,5,2,872, the disclosure of which is hereby incorporated by reference in its entirety, each of the entire disclosures of The electrode and the collecting electrode (which is in the form of a collecting electrode plate). The last field provides a discharge electrode (Fig. Hf describes one of the discharge electrodes 16 in the straight line) and a collecting electrode plate (Fig. i only describes the collecting electrode plate (8). 20 applies a current between the discharge electrode 16 and the collector electrode plate. When the flue gas 4 passes through the thunderbolt, the dust particles are charged. The charged dust particles will travel toward the collector electrode plate 18. Collect dust particles at the collecting electrode (4). The electrostatic precipitator 1 provides a slap device, which is adapted to receive The collected particles are removed by the plate 18. The slap device 22 includes a first set of hammers that are adapted to tap the upstream end of the collector plate. A -4 is included in the first set of hammers The middle end is adapted to the upstream end of the 2-electrode plate 18. The slap device 22 also includes a second set of clocks that are adapted to slap the downstream end of the seven-eight collector plate. The second hammer 26:3 is in the second group of hammers of §Hai, and is adjusted to the downstream end of the plate 丨 8. The dust removal of the number of plates 8 can be carried out in different ways. The changeable " ''flow The situation 'that is, whether the power source 20 is "applying-current" at the electrode during the slap. It can also make the slap 8 states, instead of reducing the first A of the electric product, for example, the way of normal current strike, the beat can be... According to other alternatives, the current can be increased or decreased according to the other month (compared with the normal operation period I29145.doc -16 - 200900153). If the current is applied, the electrode plate is collected. Click 'The ability of the particles to adhere to the collector electrode plate 18 will be higher than the current without applying current during the slap Another parameter of the energy culture of the collector electrode plate 18 is whether the first hammer 24 and the second hammer 26 are used for the slap in the same situation, or whether the hammer 24 is used only to perform the slap. In addition, the number of occasions that the bells 24 and 26 slap the collector electrode plate 18 will affect the amount of dust collected in the collected dust particles that can be removed from the collecting electrode plate 18. The manner in which the electrode plate 18 is collected is to be slap-collecting the electrode plate 18 in such a manner as to have a quantity of dust particles removed from the collecting electrode plate 18 and also to be dispersed in the flue gas and with the dust-removed flue gas 8-Specific characteristics of the amount of dust particles (described below) leaving the electrostatic precipitator 1. The dust particles removed from the collecting electrode plate 18 by slap are collected and transported. 2 illustrates a control system 30 that includes a data receiver 32, a data processor 34, a computing device 36, and a slam control device %. For example, the dust concentration analyzer 4 of an opacity meter analyzes the dust particles in the dust-removed flue gas 8 that has passed through the last field 14 of the deer, dad/** on a continuous or periodic basis. concentration. The data receiver 32 receives information about the pellet emission from the analyzer 4. In the case where the data receiver 32 has received the analyzer from the analyzer 4, the data receiver 32 identifies the dust particles associated with a slap event. Information about the magnitude of the mother-dust particle emission peak and the time point at which the peak of the dust emission is seen is transmitted to the data processor 34. The data section 了 'The Ten Cooler 3 4 also receives information from the slam control device 38. The information from the slap and smash control device 38 and the execution of the individual shot 129145.doc 200900153, the point between the 阙 ° based on this information 'data processor 34 to make - dust particles peak (its caused by - slap The magnitude and self-hit: the time-corresponding _. Data Processor = II I!: Peak Formation - Data Recording - This will be explained below. The information contained in the mussel material is transferred from the data processor 34 to the device %. Computing device 36 prepares and/or updates a mathematical model. The wedge type is adapted to predict the peak of the emission caused by the slap shot based on a desired duration of the slap and the slap of the previous slap (eg, by a future slap One of the magnitudes of the peak of the future emission of dust particles. The mathematical model is forwarded to the control device 38. Based on the mathematical model, control device 38 determines a suitable time for the future slap, and - a suitable type of slap to perform. The control device 38 then self-ports and transmits a signal to the slap device 22 at the desired time point, and also to the power source 20 under the condition that the current is applied to the discharge electrode 16 and the collector electrode plate. 'To perform a desired type of slap. Therefore, the signals transmitted by the control device 38 may include which current should be applied by the power source 20 during the slap, and as to whether it should operate and how the library operates. - Motor 42 (which operates the first set of hammers 24), and whether it should operate and how the second motor 44 should be operated (the information of the second group of hammers that it operates). Whenever a new data record is obtained, the next dust particle is combined. _, the mathematical model can be updated. Therefore, the control system 3 provides automatic control of the time and manner of the slap in the final field to obtain a desired low dust emission peak. Figure 3 is described by the analyzer An example of the measurement data provided by 40. The gamma axis 129l45.doc -18- 200900153 r describes the opacity signal E (% of the maximum reading on the opacity meter) and the time T (minutes) on the X axis. Dust emission peak (which is described in the form of dust particle emission peak PMP2 in Fig. 3) corresponding to the last field slap from the collecting electrode plate 18. Therefore, when the slap is performed in the last field 14, the dust emission is increased to form The dust emission peaks PI and P2 are usually about 3 to 5 minutes. The first slap and the second slap usually have a low impact on the dust emission. The reason for this fact is that The slap of the field _ or the slap of the second field 12 causes one shot from the particular field, which has increased the emission of dust particles. However, the dust particles emitted during the first slap or the second slap It will be effectively collected by the collecting electrode plate of the last field 14. Therefore, the first field is slammed or the second field is slammed with the effect often by the last field 14 (the system is located in the first field 1G and the second correction Downstream) absorbed. However, when performing a slap in the final field 14, there is no downstream field that collects the dust particles released during the slap. The amount of dust particles emitted during the dust emission peaks P1 and P2 The fluctuation of the emission of dust particles from the electrostatic precipitator 1 has a large influence on average. The amount of dust released from the collecting electrode plate 18 of the last field U is related to the average fluctuation limit of the dust emission emitted by the authority. Depending on the country in which the electrostatic precipitator i is installed, the limit value may be (for example, a 6-minute fluctuation average or a 1-day fluctuation average. This portion of the dust emission caused by the dust particle emission peaks ρι, P2 described in Fig. 3 has a significant influence on the dust emission from the electrostatic precipitator k 'Especially for short-term fluctuations in dust emission, such as the average of fluctuations in 30 minutes and shorter time periods. For example, a mean value of -6 minutes from the peak of dust emission P1 will not be met. 129145.doc -19 - 200900153 Risk of emission limits for the authorities. It has been found that the amplitude M of the dust particle emission peaks P1, P2 is largely taken as the time elapsed since the slap immediately before the slap of the dust particle emission peak p. The extent of the dust particle emission peak (4) described in Fig. 3 therefore depends on the time t elapsed since the slap of the peak η of the dust particle emission. Therefore, the amplitude M of the dust emission peak value P2 caused by the "slap R" depends on the time t elapsed since the slap immediately before the slap r". ''Amplitude' should be understood as the measurement of the large h of the dust emission peak. Theoretically, the amplitude of the dust particle emission peak p2 is the area covered by the peak Ρ2. The rise and fall of the dust emission during the slap The manner in which each slap type has its own dust emission peak/曰, 'by the mechanical characteristics of the slap device 22, whether current is applied during the slap, etc., determines the "fingerprint". In fact, it is often accurate enough to approximate the magnitude of the dust emission peak Ρ2 by the height H of the dust particle emission peak 延伸 extending above a baseline dust particle Β. The dust particle emission near the baseline dust emission (4) is between the peak PI and Ρ2 (that is, when there is no slap in the last field 14). 4 schematically illustrates the amplitudes of the dust emission peaks PI, Ρ2, Ρ3, Ρ4, and Ρ5, H1, Η2, and the corresponding time t1, t2, which have elapsed since the previous slap, by a slap. Relationship between. The slap event is initially executed such that a time tl is durationd between the slap events R1, R2'. The slap events Rl, R2, and R3 respectively cause dust emission peaks 卩丨, p2, and p3, and the dust particle emission peaks P1, P2, and p3 each have a height corresponding to a height. Soon, the time spent in each slap event increased to time t2. Therefore, the slap event R4 and the slap event R5 are each executed after the time t2 has elapsed since the previous slap 129l45.doc -20-200900153 event. The slap events 114 and 115 respectively cause the dust particle emission peak P4 and the dust particle emission peak. The dust particle emission peaks P4 and P5 each have a height H2 which is much higher than the height H1 of the dust particle emission peaks p1 to p3. It has been found that the magnitudes of the heights HI, H2 expressed as dust particle emission peaks η to w depend on the time u, t2 that has elapsed since the slap event immediately before the slap event that caused the dust particle emission peak. Therefore, the peak of the dust emission caused by the slamming event ruler 4 is determined by the height H2 depending on the time u that has elapsed since the previous slamming event R3. Figure 5 depicts an example of a mathematical model based on The peak of the dust particle emission Η, and the measurement of the corresponding time t since the slamming event immediately before the slamming event that caused the peak of the dust emission. Two measurements have been made, which are described in In Figure 5, each measurement has resulted in a data record that includes the height H of the dust emission threshold and the time t since the previous slam event. In addition, a fictitious data record has been added, Is located near zero (real The peak value of the 丨% at the minute is). The fictitious data is recorded by the fact that the continuous slap of the collecting electrode plate 18 does not appear to be peak (because dust particles are not collected under such conditions). The time is the peak of the time since the previous slap. t 1 t (minutes) _ 0 ..... 1 I . 330 1 _ II .... 4300 Ο V/ __ III 11540 j / 85 Table 1: Record of the time and corresponding peaks since the previous slap. 129145.doc •21 - 200900153 It has been found that 'by the selected slap--the peak of the selected dust emission peak 自 and self-tightening The logarithm of the time that has elapsed since the slap of the selection of the dust particles that caused the selection of the dust particles is proportional to the number of bases. Therefore, the height of the bee value (H) is naturally correct, A curve fit is performed between the logarithms. The obtained equation is: H(t) = 7.2*ln(t[min])-5.6[〇/〇] (equation j)) Equation 1.1 is used as a mathematical model , the sentence of the sentence Yizi I have a description of the wrong by a selected shot f.: future slap) will cause - the selected dust emission peak (for example, The height H of the dust emission peak) can be determined based on the selected (four) (four) connected to the slap prior to the slap shot, and the timed learning model and appropriate conditions (eg, maximum license Γ) control device 38 can determine when Execution - slap between si. If, for example, the environmental rule is such that the peak of the dust emission peak is high (because the 6-minute two exceeds the risk), then the limit of the needle (four) solution is at t = e_] + 5.6. ) / 7.2 [minutes ] ^ by introducing Η = 50% into Equation 2 (Equation 2)) t = e〇〇W + 5,v,2rv ^ ^ ^^#,XTBffa1t: [刀刀]= 2350 [Minute] (Equation 22, since the previous slap has been _ " determined by the mathematical model), at the time of Cai Zhongzhong (four), he has borrowed a slap. The control device 38 can instruct the slap device 22 to perform a natural logarithmic function adapted to be between the gaze and the time between one of the slap and the slap and the previous slap. The 129145.doc -22- 200900153 relationship fact magnitude 成 is proportional to In (time t) by the following physical background: the longer the time t since the previous slap, the accumulation on the collecting electrode plate 18 The more dust particles there are. The more dust particles accumulated on the collecting electrode plate 18, the more dust particles will be released during the slap. However, as the time since the previous slap is increased, the dust particles will experience increased cohesion while collecting on the electrode plate 18. This cohesion compensates for the increase in the magnitude of the peak of the dust emission. The total effect of the longer time t since the previous slap will result in an increase in the amplitude of the dust emission peak, but the increase will be less than the viscosity of the dust particles on the collecting electrode plate as illustrated by a linear function The increase caused by the gathering. As an alternative to the natural logarithmic function, it is also possible (although sometimes poor) to utilize other logarithmic functions, as well as approximations of logarithmic functions. An approximation by a logarithmic function means, for example, a mathematical function similar to a logarithmic function, a trigonometric function, a piecewise linear curve fitting, and the like. Figure & illustrates an example of how to predict the height HF of a future dust particle emission peak PF due to a given time t from the previous slap event. . Figure 6b illustrates an example of how the time iF of the event R1 to be elapsed is predicted from Equation 2" based on a given height of a future dust emission peak pF. The mathematical model according to Equation 1.1 is based on only three data records plus fictitious data records. A mathematical model can also be obtained from only one or two data records plus the fictitious data record. Mathematics based on these data records 129145.doc -23- 200900153 :: Type can be regarded as a "starting model". However, the condition in the electrostatic dust collection m: 曰化'因&, if the mathematical model is not updated, the mathematical model may become unsuitable for the control of the slap.

If the first time: step C, the two obtained since the start of the operation of the electrostatic precipitator 1 Or more information records A mathematical model is provided. If, on the other hand, a mathematical model is available, the mathematical model is updated with a new data record containing the post. In step D, 'based on the mathematical model control is to be executed - the slap N 1 The time of introduction is 1. The time is usually used for the control. This condition—the example—the height of the dust emission peak', does not exceed a certain value Hmax. Height Hn+i It is set as in the form, and is introduced into the mathematical model by 129145.doc -24- 200900153. 接!

Sequence A, B , c, ^di^, has a loop, so that at the end of step D, /. will be 又»又=为N+1, and start step A, which is described in Figure 7. This is Ganzi-T Tian has When you slap the slap event, you will get a new data record, 2 and 3 take the measurement height of the peak of the dust particle emission and the corresponding time ^. The new-before material record can be used to update the mathematical model to make the mathematical model better than the prediction. The dust particle emission peak height h as a function of time t. Because of the loop 'cause This can continuously update the mathematical model such that the predicted dust particle emission peak height. More suitable for the white 'electrostatic precipitator 1 operating conditions may be two during operation: such changes include: collecting electrode plate 18 The dust collected on the second part: two: change, the change of the characteristics of the flue gas 4, the electrostatic precipitator 1: 'chemical 4, etc.. In view of such possible changes, when the mathematical model is updated in step C, it is suitable for the ^ model.

Although Table 2 illustrates—a very simple method of transitioning data records, giving new data records a greater impact on the updated mathematical model (compared to the old data records), it should be understood that many different types of nature can be used. A well-known data filter device 1 can learn the setting of a data filter for a static electrostatic dust collection of a suitable component by routine experimentation. It should be understood that many alternative data filters are available. Preferably, a quality assessment is performed to give the data record a higher impact on the mathematical model update (as compared to less reliable data). The quality assessment may, for example, give a lower weight to the information that has been obtained during the disturbance of the detected program.

model. According to an alternative embodiment, a bias term is added to the mathematical model to allow for automatic adjustment during continuous operation by utilizing one of the peaks of the k-dust emission peak caused by the selected slap and the tightness between the selected slaps The relationship between the time between the previous slaps and the time. This bias is updated based on each new data record rather than updating the core of the mathematical model. Because &, the mathematical model is updated via the partial term and thereby adjusting the force to suit the actual operating conditions without changing the basic relationship. This bias term causes the mathematical model to move between a series of curves, but does not redefine the shape of the curve. This control can be implemented by using an equation of the form: 9

Hpredictcd (t) = in (t) + biaSN (Equation 3 1) Refinement - The whole term (which is calculated as the difference between the measured and predicted amplitude of the dust emission peak) is used to update the partial term: (Special Formula 3·2) biasadjust = Hmeasured(t) . Hpredicted(t) The partial term can now be updated by the following equation: bias>j+i — bias^ + bias a- adjust (#^3.3) In actual operation, as described above, the control of the slap device 22 using the partial term can be implemented in the control block (which uses the differential of the above mathematical model). In the control block, the slope of the fitted curve is used as the starting offset. From ##1.1, you can derive the level of 72. The slope of 7.2 is derived and can be shifted. The control block will perform the following operations: • Pairing the dust emission peak (Special Formula 3.4) (Equation 3.5) First, calculate the difference based on the selected peak value and the height of the previous peak value and the elapsed time t. ΔΗ = HN - Hn., Δί — ϊν - tjsj.] I29145.doc -27- 200900153 Then calculate the desired peak height change to reach the desired peak height Hdesired · (Special 3.6) (Equation 3.7) △Hrequired = After Hdesired - HN, if Δί is not zero, then calculate biaSnew : biasnew = ΔΗ / At Now the offset can be updated: biasN+1 = biasN * biasfilter + biaSnew * (i_biasfiIter) (Equation 3 8) Then you can calculate the duration The required change in time: △^required = AHrequired / biaSN+1 (Equation 3 9) Then the time from the mathematical model to the next scheduled slap event is calculated as: ~N+1 ==== (Equation 3.10) Finally, N = and start the procedure again with the new data record. The speed of the preferred rapid adaptation to the changing conditions is typically set to a value within the range of GuG8. The MaSfilier factor takes into account measurement errors, accidental aberrations of measured values, and the like. Figure 8 illustrates the effects of different types of slaps. As explained above, the slap can be performed in different ways. For example, the slap can be performed by (4) (4) the first hammer, the second hammer 26, or by operating only one of the hammers 24, %. , at , 'RA indicates that only the first hammer 24 is used for the slap. Each slap ^ results in - having a height of the dust emission peak... and (1) but the slap with the hammer 24 may result in the raft collecting electrode plate 18 not being sufficiently dusted. Therefore, the use of a certain interval of enthusiasm -, the rich one thousand intervals to operate two hammers 24,% of the slap 129145.doc • 28- 200900153 Can. When the slap of the -RB type is performed, the beat_ results in a very large dust emission peak P4 (which has a height H4) which is accumulated on the collecting electrode plate during the slap of the ra type. Some dust particles are released: true. When a second RB type slap is performed, the slap is performed on the collecting electrode plate 18 on which no accumulated dust is accumulated, so that the southmost H5 of the dust particle emission peak p5 is lower than the height of the dust emission peak p4. m. It will be clear from Fig. 8 that the time elapsed between the slaps is constant, and is _. The peaks obtained by the slap of the RA slap type are used, and (b) the peaks p4 and p5 obtained by the slap of the slap type are different. In addition, after the slap type of the RA slap type directly performs a rb slap type slap, the dust particle emission peak obtained is directly executed after the other slap slap type slap - the lion strike type slap The obtained dust particle emission peak P5 is high. In order to consider this characteristic, it is preferable to use a specific mathematical model for each type of slap, so that the peak height of the dust emission can be accurately predicted for each slap type. Thus, with the example depicted in Figure 8, it is preferred to employ a mathematical model for each slap of the RA slap type and another mathematical model for each slap of the slap type. If an electrostatic precipitator i is designed to employ more than one type of slap I (for example, slap from both sides of the collecting electrode plate 18 and slap only from the side of the collecting electrode plate 18) Preferably, the method and the control system 3 are adapted to select an appropriate mathematical model relative to the type of slap to be performed, and to apply the time duration prior to the calculation of the next slap of the particular type of application. The mathematical model. Each data record (which contains the peak height H of the dust emission and the elapsed time = information) can be additionally provided - a first label ruler indicating which type of slap is performed 129145.doc -29- 200900153 types. This first-standard iron R is used to ensure that the relevant mathematical model is updated, that is, the mathematical model corresponding to the specific type of slap, the data record of the peak value 较佳 preferably contains high (four), time == slap type _. This data record is used to update the mathematical model corresponding to the RB tap type. In addition, the mathematical model is better (four) to consider the type of slap before the slap as described in (4) History. Preferably, the mathematical model considers the following: this method is performed by: an RA slap type = slap in the first slap type that causes the dust particle emission peak P4 = RB slap The type of slap is before the slap of the type of slap that causes the peak of the dust emission. In order to make it possible to consider the historical data, it is better to provide a second standard. The second indicator indicates a successful slap under the previous slamming event or as needed for several previous slamming events. There are several different ways to consider the second history of the type of slap. One method is for a type of slap to be executed and the desire: two: slap: each combination of a slap type that has been executed before adopts a specific number: two strikes, a case T, with reference to FIG. 8' before Type of hit: When hitting, it will be used for the slap type of one RB slap type—the math model will use another mathematical model for the slap of one slap type when slap of another RB type. Row! :: Use a certain type of compensation factor' to consider the type of the previous slap. For example, by a mathematical slap corresponding to the -RB slap type: the calculated dust particle height can be increased (for example) by 5% if the previous slap event is a slap of -RA 4 The previous slap 129I45.doc •30· 200900153 can reduce the “column” 5% for the slap type slap. Therefore, the data record of the dust emission peak P4 will preferably contain the dust emission height. H4, the elapsed time u, the slap of the slap type as the first tag, and the slap of the RA slap type as the second tag before the slap of the peak 卩4. This data record is used to update the mathematical model corresponding to the slap type of the slap slap type, and to compensate for the fact that a rabe is the type of slap before the slap of the rB slap type. ° According to the emission standard used in the country, the conditions for controlling the shock 3 扛 slap are set. The emission limit of the dust particles after the last field 14 may be (〇) 1 〇 mg/Nm dry gas (which is a 6-minute fluctuation average, or as a one-day fluctuation average). Therefore, there is usually a preset fluctuation average limit value, and the tap is controlled relative to the preset fluctuation average limit value. For example, the actual fluctuation average using an opacity count can be calculated as: g—average (Equation 4 A ) where η is the average period of the fluctuation period (for example, 6 minutes or one day of sampling points. Based on measured baseline dust particles The knowledge of the launch (ie, the emission of dust particles between two beat events), one of the conditions that occurs during the 6-minute day period by one of the dust-emissions caused by the slap: large: Based on this simulation, the peak amplitude of the dust emission can be determined. For example, the peak of the maximum dust emission is high and the peak height of the maximum dust emission is set as the input to the control of the dust. The set 38 can be based on a mathematical model to avoid the slap of the last field 14 of the dust thief 1 of this dust-like emission peak exceeding the maximum enthalpy interval. Therefore, the control device 38 borrows The slap is controlled by controlling the time between the slap and a future slap, and/or the type of slap to be performed. Figure 9 illustrates an electrostatic precipitator I" in accordance with an alternate embodiment. The design of the dust collector 101 is similar to that of the electrostatic precipitator described above. The control system 30 includes a computing device 136 and a slam control device 138 (which is operable to initiate electrostatic precipitator) The slap control device 138 controls the current f month condition of the last field during the slap, that is, whether the power source 120 applies a current between the electrodes (not shown in Fig. 9). The control device 138 also controls a slap device 122 to control whether it should operate and how the first motor 42 should be operated (which operates the first group of hammers (not shown in Figure 9)), and whether it should operate and how the second motor should operate. 144 (which operates a second set of hammers (not shown in Figure 9)). The computing device is in the form of a PID controller 136 and is operable to determine when the slam control device 138 should initiate a slap in the last field 114. pm control The information is received from the dust concentration analyzer 14A. The dust particle analyzer 140, for example, a transparency meter, analyzes the dust-removed flue gas 8 that has passed through the last field U4 on a continuous or periodic basis. The concentration of dust particles. About the measured The amount of opacity (i.e., the amount of dust caused by the slap by the last field 114 - the amplitude of the particle emission peak amplitude of the particle emission peak sent by the analyzer 140) is from the dust particle controller 1 36 (comparison The measurement amplitude and the dust target value. (4) The controller 136 adjusts, as necessary, the time required to indicate the slap control device 138 to perform another slap of the collecting electrode plate of the last field 114. Therefore, the PID controller 136 Used for automatic tracking of the time 129M5.doc -32- 200900153: dust:: two leads - as close as possible to the peak of the dust emission peak "the value of the granule emission of the bee value of the Tang 1 ~ 厪) use The fact that one of the peaks of the dust emission selected by one of the selected slaps is selected to be connected to the previous slap-time.../:,...There is a relationship between the selected slap and the day between the temples ^ The controller 136 provides when the automatic control of the slap should be performed in order to obtain the magnitude of the _: 2 dust = shot peak.

It should be understood that the specific embodiments described above may be within the scope of the appended claims. Many variations. : As shown above, the control system 3 can be used to determine the expected peak height after a certain time since the previous slap, or to determine the dust emission in order to obtain a certain height. The peak time is expected. It should be understood that other control strategies can also be used. For example, the control device (4) can be adapted for iterative calculations to obtain the time and the desire to use the slap protocol sequence to provide low dust emission. This sequence can be used as an example similar to the sequence described in Fig. 8.

Another possibility: (also set the clock 'for example, only the hammer 24 is used, so that only the side of the slap is collected by the slap. Heart: The text has stated that the mathematical model adopts a relationship 'the peak of the dust shot in the relationship The height is proportional to the number of hours since the previous slap (specifically, the logarithm). It should be understood that other mathematical model types can be used. For example, in some cases, the data record is adapted to 'linear. The model, or -index model may be sufficiently accurate, especially in the context of the relevant operating range of the data record disc for a relatively narrow range of time since the previous slap. ' As explained above, dust emission The height H of the peak is often a good approximation of the magnitude of the peak of the dust emission. As an alternative to the peak height H, the magnitude of the peak of the dust emission can also be represented by other quantities (such as the area of the peak of the dust emission, etc.). As explained above, an independent mathematical model is preferably used to predict the peak height of each type of slap. It should be understood that if the peak heights of some types of slaps are found to be similar, then slaps The same mathematical model can be used for the type. For example, the right finds that only the slap of the first set of hammers 24 provides a peak height similar to that of the second set of hammers 26, then the two slap types can utilize the same mathematics. Model. As explained above, it is often better to control the time in the last field 14 to be executed - the time before the slap, but it can also be operated a fixed number of times to perform the 129I45.doc •34-200900153 slap, for example, fixed every day. The hour is performed by slap-two owing or twice. In this case, the control system 30 can be based on a mathematical model for different types of slaps (4) which type of slap is to be performed in order to avoid large dust emission peaks, and Still avoiding the accumulation of dust over time on the collecting electrode plate 18. As explained above, it is often preferred to have the control system 3() control the time it takes to perform a slap and the type of slap to be performed. Although the control system 3 and the method have been described above to control when

And/or how to perform a slap, but the control system can also be used to/or predict the magnitude of the peak of the dust emission over a certain period of time, or the time before the peak of the dust emission of a certain amplitude is predicted. .
