The execution of the fault warning method of the gypsum cyclone will be described in detail below.

[0050] As an important equipment in the desulfurization system of a power plant, the gypsum cyclone is a key equipment in the primary dehydration system. The working status of the gypsum cyclone affects the status of the entire dehydration system. In order to achieve real-time warning of the blockage degree of each cyclone and the wear degree of the sand settling nozzle without stopping the gypsum cyclone dehydration system and dismantling the cyclone, sand settling nozzle and other local equipment, the gypsum cyclone in the desulfurization system is modified.

[0051] Specifically, in the embodiment of the present application, the shut-off valve in the gypsum cyclone is changed from a local manual door to a remote electric valve, and the pressure gauge of the gypsum cyclone is changed from a surface gauge to a pressure transmitter to transmit the pressure value in real time. The remote electric valve and the pressure transmitter can receive the control instructions issued by the processing device in the desulfurization system corresponding to the gypsum cyclone, automatically open or close the electric valve under the control of the control instructions, and upload the pressure data to the processing device in real time.

[0052] Through the above-mentioned changes to the gypsum cyclone, remote monitoring of the gypsum cyclone is achieved.

[0053] See also Figure 2 The embodiment of the present application provides a fault warning method for a gypsum cyclone, wherein the gypsum cyclone includes M cyclones and N sand settling spouts, wherein M and N are positive integers, and the method includes: step S1, step S2 and step S3.

[0054] Step S1: judging whether the gypsum cyclone has a cyclone blockage fault according to the difference between the current pressure value of the gypsum cyclone and the standard pressure value under the same working condition;

[0055] Step S2: If yes, locate the position of the cyclone with the blockage fault among the M cyclones; if no, calculate the wear coefficients corresponding to the current N sand settling spouts respectively, and determine whether the corresponding sand settling spout has a sand settling spout wear fault according to the wear coefficients;

[0056] Step S3: Calculate the corresponding sand settling spout compensation coefficient according to the wear coefficient of each sand settling spout, and use the sand settling spout compensation coefficient to compensate the corresponding cyclone.

[0057] The following is a detailed description of the execution process of the fault warning method for the gypsum cyclone.

[0058] The gypsum cyclone includes M cyclones and N sand settling spouts, wherein M and N are positive integers. It should be noted that M and N can be the same positive integer or different positive integers. In the embodiment of the present application, M and N are the same positive integer, that is, the cyclones and sand settling spouts in the gypsum cyclone have a one-to-one correspondence.

[0059] In the embodiment of the present application, the effect of cyclone blockage on the pressure relief capacity of the gypsum cyclone is reverse, that is, the more serious the cyclone blockage is, the smaller the pressure relief capacity of the gypsum cyclone is, and the corresponding pressure value in the gypsum cyclone will be greater; the effect of sand settling nozzle wear on the pressure relief capacity of the gypsum cyclone is positive, that is, the more serious the sand settling nozzle wear is, the greater the pressure relief capacity of the gypsum cyclone is, and the corresponding pressure value in the gypsum cyclone will be smaller.

[0060] Before step S1, the fault warning method of the gypsum cyclone further includes: establishing a standard pressure value data model based on the relationship between the pressure value of the gypsum cyclone and the density of the gypsum slurry and the number of cyclones.

[0061] Specifically, the cyclone exits when the shut-off valve of the gypsum cyclone is closed; when the shut-off valve of the gypsum cyclone is opened, the higher the density of the gypsum slurry input, the more cyclones are correspondingly input, and vice versa, the lower the density of the gypsum slurry input, the fewer cyclones are correspondingly input. The more cyclones are input, the greater the pressure of the gypsum cyclone; the fewer cyclones are input, the smaller the pressure of the gypsum cyclone. From the above description, it can be seen that when the gypsum slurry density and the number of cyclones input are determined, there will be an ideal standard gypsum cyclone pressure. Through experiments, multiple groups of standard pressure values ​​corresponding to different gypsum slurry densities, different working conditions and different numbers of cyclones input are obtained, and a standard pressure value data model corresponding to the gypsum cyclone is constructed.

[0062] By constructing the standard pressure value data model, the corresponding standard pressure value can be obtained after obtaining the current gypsum slurry density and the number of cyclones. In other words, the corresponding standard pressure value under the same working condition can be obtained through the standard pressure value data model.

[0063] Step S1: judging whether a cyclone blockage fault occurs in the gypsum cyclone according to the difference between the current pressure value of the gypsum cyclone and the standard pressure value under the same working condition.

[0064] Specifically, the standard pressure value corresponding to the gypsum cyclone under the current working condition can be obtained through the constructed standard pressure value data model. If the gypsum cyclone has a cyclone blockage failure, the total pressure value of the gypsum cyclone will increase, and the overall blockage of the gypsum cyclone can be judged by the change of the total pressure value of the gypsum cyclone.

[0065] Optionally, in the embodiment of the present application, if the difference between the actual pressure value and the standard pressure value under the same working condition is greater than a preset value, it is determined that a cyclone blockage fault has occurred in the current gypsum cyclone; if the difference between the actual pressure value and the standard pressure value under the same working condition is less than a preset value, it is determined that the current gypsum cyclone is in a normal operating state. It should be noted that the setting of the preset value can be set according to experience.

[0066] Step S2: If yes, locate the position of the cyclone with blockage failure among the M cyclones; if no, calculate the wear coefficients corresponding to the current N sand settling spouts respectively, and determine whether the corresponding sand settling spout has a sand settling spout wear failure according to the wear coefficients.

[0067] After it is determined through the above step S1 that the gypsum cyclone has a cyclone blockage fault, it is necessary to further determine the specific position of the cyclone where the blockage fault occurs among the multiple cyclones.

[0068] Optionally, among the M swirls, the one that has a blockage failure may be one of the M swirls, or more than one of the M swirls may have a blockage failure. Therefore, in order to accurately determine the position of the swirl that has a blockage failure, multiple swirls are tested separately to determine whether the swirl has a blockage failure.

[0069] For details, please refer to Figure 3 , locate the position of the cyclone with the blockage fault among the M cyclones, including:

[0070] Step S21: select one cyclone from the M cyclones as the standard cyclone and record the current pressure value P0 of the gypsum cyclone;

[0071] Step S22: turning on the standard cyclone, turning off one of the M-1 cyclones other than the standard cyclone, delaying for a first preset time, and recording the current pressure value Pi of the gypsum cyclone;

[0072] Step S23: calculating the blockage coefficient corresponding to each vortex except the standard vortex according to the first calculation formula in turn, and determining the vortex whose blockage coefficient exceeds the first preset threshold as the faulty vortex with a blockage fault.

[0073] It should be noted that, among the M-1 swirls, only one swirl is in the closed state at a time, and the standard swirl is closed after the calculation of the blockage coefficient corresponding to each swirl among the M-1 swirls is completed.

[0074] In the embodiment of the present application, one of the M cyclones is randomly selected as the standard cyclone. It should be noted that when the gypsum discharge pump corresponding to the gypsum cyclone is in operation and multiple cyclones in the gypsum cyclone are in operation, the standard cyclone will not be put into operation but will be in a closed state.

[0075] When it is determined through step S1 that a cyclone blockage failure occurs and further analysis is needed to determine the position of the cyclone where the blockage failure occurs, first record the pressure value P0 of the current gypsum cyclone, then turn on the standard cyclone, and turn off the selected cyclone, observe the pressure of the gypsum cyclone, and after the first preset time, when the pressure of the gypsum cyclone is stable, the processing device can automatically compare the pressure values ​​of the gypsum cyclone before and after switching the cyclone, and obtain the blockage coefficient of the cyclone according to the first calculation formula. Then turn on the cyclone, turn off the next cyclone, and after the first preset time, when the pressure of the gypsum cyclone is stable, calculate the blockage coefficient of the next cyclone according to the first calculation formula, until the blockage coefficient of each cyclone except the standard cyclone is calculated.

[0076] That is to say, by switching different swirls and comparing the pressure value difference before and after, the blockage coefficient corresponding to the different swirls is calculated, so as to determine whether the swirl has a blockage failure; wherein, the first preset time length and the first preset threshold value can be set according to specific needs. In the embodiment of the present application, the first preset time length is two minutes.

[0077] As a possible implementation, the first calculation formula is as follows:

[0078]

[0079] In the formula, K i堵塞 represents the blockage coefficient of the i-th cyclone among the M-1 cyclones, P0 represents the pressure value of the gypsum cyclone before switching to the standard cyclone, Pi represents the pressure value of the gypsum cyclone when switching to the i-th cyclone among the M-1 cyclones, K i沉沙嘴补偿 represents the sand spout compensation coefficient corresponding to the i-th cyclone; wherein i is a positive integer greater than 0 and less than M.

[0080] According to the above-mentioned first calculation formula, the blockage coefficient corresponding to each cyclone except the standard cyclone is calculated. The blockage degree of each cyclone can be judged by the blockage coefficient of each cyclone. Specifically, the physical meaning of the blockage coefficient of the cyclone is the flow ratio of the gypsum slurry flowing through before and after the blockage. Different values ​​of the blockage coefficient indicate different degrees of blockage, and different treatment measures can be taken accordingly. For example, when the blockage coefficient is greater than 0.2, increase the flushing time with clean water to deal with it. When the blockage coefficient is greater than 0.4, disassemble the cyclone for treatment. By adopting different treatment methods for cyclones with different blockage coefficients, the normal operation of the gypsum cyclone can be guaranteed to the greatest extent and the production efficiency can be improved.

[0081] It should be noted that in the first calculation formula above, K i沉沙嘴补偿 This parameter is because: the deviation between the actual pressure and the standard pressure of the gypsum cyclone under specific working conditions depends not only on the blockage of the cyclone, but also on the wear of the sand settling nozzle. After the cyclone has been running for a long time, the sand settling nozzle is worn, the pressure relief capacity increases, and the flow resistance gradually decreases compared with the standard cyclone. The greater the wear of the sand settling nozzle, the stronger the pressure relief capacity, which will also cause the pressure of the gypsum cyclone to become lower. Considering that the wear of the sand settling nozzle is a relatively slow process for the blockage of the cyclone, the wear degree of the sand settling nozzle can be dynamically calculated to obtain the wear coefficient of the sand settling nozzle corresponding to each cyclone, and compensate it to the actual pressure of each cyclone, and then compare it with the standard pressure of the gypsum cyclone, thus eliminating the impact caused by the blockage of the cyclone.

[0082] It should be noted that K i沉沙嘴补偿 The method for solving this parameter will be explained in detail in the following content.

[0083] Optionally, since the wear of the sand settling spout is a relatively slow process for the cyclone blockage, a target value is set. When the calculated sand settling spout compensation coefficient is less than the target value, it means that the wear of the sand settling spout has a small impact on the cyclone blockage and can be ignored at this time, that is, sand settling spout compensation is not required at this time; when the calculated sand settling spout compensation coefficient is greater than the target value, it means that the wear of the sand settling spout has a large impact on the cyclone blockage and compensation needs to be considered at this time, that is, sand settling spout compensation may be required at this time.

[0084] In order to clearly illustrate how to determine the position of the cyclone where a blockage failure occurs among the M cyclones in the gypsum cyclone, an example is given here for illustrative explanation.

[0085] For example, in the embodiment of the present application, both M and N are 6, that is, the gypsum cyclone includes 6 cyclones and 6 sand settling nozzles. It should be noted that the value 6 is only an example value, and its specific value is not limited. Then, the process of determining the cyclone with a blockage failure among the 6 cyclones is as follows: Assume that the 6 cyclones are cyclone A, cyclone B, cyclone C, cyclone D, cyclone E and cyclone F, and the 6 sand settling nozzles are sand settling nozzle A, sand settling nozzle B, sand settling nozzle C, sand settling nozzle D, sand settling nozzle E and sand settling nozzle F, and the sixth cyclone, namely cyclone F, is determined as the standard cyclone. First, record the total pressure value P0 of the gypsum cyclone before the cyclone switch is performed; then turn on the standard cyclone F, turn off the first cyclone, that is, cyclone A, delay for 2 minutes, record the corresponding pressure value P1 of the gypsum cyclone when cyclone A is turned off, and calculate the blockage coefficient K of cyclone A through the first expression above. 1堵塞 Open cyclone A, close the second cyclone, that is, cyclone B, delay for 2 minutes, record the pressure value P2 corresponding to the gypsum cyclone when cyclone B is closed, and calculate the blockage coefficient K of cyclone B through the first expression above 2堵塞 Open cyclone B, close the third cyclone, namely cyclone C, delay for 2 minutes, record the pressure value P3 corresponding to the gypsum cyclone when cyclone C is closed, and calculate the blockage coefficient K of cyclone C through the first expression above 3堵塞 Open cyclone C, close the fourth cyclone, i.e., cyclone D, delay for 2 minutes, record the pressure value P4 corresponding to the gypsum cyclone when cyclone D is closed, and calculate the blockage coefficient K of cyclone D through the first expression above. 4堵塞 Open cyclone D, close the fifth cyclone, that is, cyclone E, delay for 2 minutes, record the pressure value P5 corresponding to the gypsum cyclone when cyclone E is closed, and calculate the blockage coefficient K of cyclone E through the first expression above 5堵塞 Then turn on the cyclone E and then turn off the standard cyclone F to end the whole process.

[0086] In the above process, any one of swirl A, swirl B, swirl C, swirl D and swirl E may be in a non-operational state. If the swirl is in a non-operational state, the swirl is automatically skipped in the above process, and the next swirl is judged.

[0087] It should be noted that the cyclone switching comparison can be achieved through a processing device in the gypsum cyclone, such as a distributed control system (DCS) automatic function group. The triggering of the automatic function group of the DCS can be done manually or automatically. The automatic method requires a trigger condition, which can be a regular trigger or a specific condition trigger, and is set according to the actual situation of the industrial site. Generally, an automatic method is adopted to implement the startup function group, such as once a week or when the deviation between the actual pressure and the standard pressure of the gypsum cyclone under the current working conditions is greater than the set value, the startup function group is triggered to achieve early warning of the blockage of the M cyclones in the gypsum cyclone. Optionally, in an embodiment of the present application, the set value is 0.02Mpa.

[0088] Through the method in the above steps, after preliminarily judging that a cyclone blockage fault occurs in the gypsum cyclone, the cyclone with the blockage fault can be quickly and accurately located among multiple cyclones, thereby avoiding time-consuming and labor-intensive searching for the cyclone with the blockage fault and improving production efficiency.

[0089] The cyclone blockage warning is used to confirm that the cyclone is in an unblocked state, and then the cyclones are compared with the standard cyclones one by one, and the wear coefficient of the sand settling spout is calculated one by one.

[0090] For details, please refer to Figure 4 , respectively calculate the wear coefficients corresponding to the current N sand settling spouts, and determine whether the corresponding sand settling spout has a sand settling spout wear failure according to the wear coefficients, including:

[0091] Step S31: Record the current pressure value P1 of the gypsum cyclone;

[0092] Step S32: Turn on the standard cyclone, turn off one of the M-1 cyclones other than the standard cyclone, and after a delay of a second preset time, record the current pressure value P of the gypsum cyclone. i磨损 ; and calculate the wear coefficient corresponding to each sand settling nozzle except the sand settling nozzle corresponding to the standard cyclone according to the second calculation formula, the second calculation formula is as follows:

[0093]

[0094] In the formula, K i沉沙嘴磨损represents the wear coefficient of the sand trap corresponding to the i-th cyclone among M-1 cyclones, P i磨损 represents the pressure value of the gypsum cyclone when switching to the i-th cyclone among the M-1 cyclones, and P1 represents the pressure value of the gypsum cyclone before switching to the standard cyclone;

[0095] Step S33: determining the sand settling spout whose wear coefficient exceeds the second preset threshold as a sand settling spout wear failure.

[0096] That is to say, based on the standard cyclones determined in the above method, the selected cyclones are closed in turn, the history of the gypsum cyclone is observed, and after the pressure of the gypsum cyclone is stabilized, the pressure of the gypsum cyclone before and after the switch is compared, and the wear coefficient of the sand settling nozzle corresponding to each cyclone is calculated according to the above second calculation formula.

[0097] Based on the above embodiment, the gypsum cyclone includes 6 cyclones and 6 sand settling nozzles. It is assumed that the 6 cyclones are cyclone A, cyclone B, cyclone C, cyclone D, cyclone E and cyclone F, and the 6 sand settling nozzles are sand settling nozzle A, sand settling nozzle B, sand settling nozzle C, sand settling nozzle D, sand settling nozzle E and sand settling nozzle F. The sixth cyclone, i.e., cyclone F, is determined as a standard cyclone, and there is a one-to-one correspondence between the cyclones and the sand settling nozzles.

[0098] Then, the process of determining the wear coefficients corresponding to the sand settling spouts A, B, C, D and E is as follows: first, confirm that the gypsum discharge pump corresponding to the gypsum cyclone is in operation and the gypsum cyclone has been put into operation, and confirm that there is no cyclone blockage, that is, the blockage coefficient of all cyclones in operation is less than 0.1; then record the total pressure value P1 of the gypsum cyclone before the cyclone switching is performed; then turn on the standard cyclone F, turn off the first cyclone, that is, cyclone A, delay for 2 minutes, and record the pressure value P1 of the gypsum cyclone corresponding to the cyclone A when the cyclone A is turned off. 1磨损 The wear coefficient K of the sand trap A corresponding to the cyclone A is calculated by the second expression above. 1沉沙嘴磨损 Open cyclone A, close the second cyclone, cyclone B, delay for 2 minutes, and record the pressure value P of the gypsum cyclone when cyclone B is closed. 2磨损 The wear coefficient K of the sand trap B corresponding to the cyclone B is calculated by the second expression above. 2沉沙嘴磨损 Open cyclone B, close the third cyclone, cyclone C, delay for 2 minutes, and record the pressure value P of the gypsum cyclone when cyclone C is closed. 3磨损 The wear coefficient K of the sand trap C corresponding to the cyclone C is calculated by the second expression above. 3沉沙嘴磨损Open cyclone C, close the fourth cyclone, which is cyclone D, delay for 2 minutes, and record the pressure value P of the gypsum cyclone when cyclone D is closed. 4磨损 The wear coefficient K of the sand spit D is calculated by the second expression above 4沉沙嘴磨损 Open cyclone D, close the fifth cyclone, which is cyclone E, delay for 2 minutes, and record the pressure value P of the gypsum cyclone when cyclone E is closed. 5磨损 The wear coefficient K of the sand trap E corresponding to the cyclone E is calculated by the second expression above. 5沉沙嘴磨损 Then turn on the cyclone E and then turn off the standard cyclone F to end the whole process.

[0099] The above-mentioned process of calculating the wear coefficient of multiple sand settling spouts can be realized by the sequential control function group of the DCS in the gypsum cyclone. The function group can be triggered manually or automatically. The automatic method requires a trigger condition, which can be a regular trigger or a conditional trigger, determined according to the actual situation of the industrial site. Generally, the function group is started automatically, such as once a week or when the deviation between the actual pressure of the cyclone and the standard pressure under the current working conditions is less than the calibration value to trigger the start function group. Optionally, in the embodiment of the present application, the calibration value is 0.01MPa.

[0100] Step S3: Calculate the corresponding sand settling spout compensation coefficient according to the wear coefficient of each sand settling spout, and use the sand settling spout compensation coefficient to compensate the corresponding cyclone.

[0101] As a possible implementation, the actual pressure of the gypsum cyclone depends not only on the blockage of the cyclone, but also on the wear of the sand settling nozzle. Therefore, the wear coefficient of the sand settling nozzle corresponding to each cyclone can be obtained and compensated to the actual pressure of each cyclone.

[0102] Specifically, the wear coefficient of each sand settling nozzle is linked to the compensation coefficient of each cyclone according to the following third calculation formula. In the embodiment of the present application, the third expression is as follows:

[0103] K i沉沙嘴补偿 =(1 / K i沉沙嘴磨损 ) 2

[0104] In the formula, K i沉沙嘴磨损 It represents the wear coefficient of the sand settling spout corresponding to the i-th cyclone.

[0105] According to the third calculation formula, the wear of each sand settling nozzle can be compensated for the pressure of the gypsum cyclone. When the actual pressure value of the gypsum cyclone after compensation is compared with the standard pressure value of the gypsum cyclone under the same working condition, the influence of the wear of the sand settling nozzle on the comparison result is eliminated.
