Description

Technical Field

[0001] The present invention relates to the technical field of intelligent control of desulfurization devices in thermal power plants, and in particular to a filtered water pit pump operation control method, a filtered water pit pump operation control device, a machine-readable storage medium and an electronic device. Background Art

[0002] The filter water pit pump is an important equipment of the secondary dehydration subsystem of the flue gas desulfurization device in thermal power plants. The slurry in the absorption tower of the desulfurization device is discharged to the primary dehydration cyclone through the gypsum discharge pump. The cyclone separates the slurry into solid and liquid. The thin slurry flows back to the absorption tower, and the concentrated slurry flows into the vacuum belt conveyor as the bottom flow. The vacuum belt conveyor dehydrates the concentrated slurry to form gypsum. The thin slurry drawn out by vacuum flows into the filter water pit. The filter water pit pump draws the thin slurry in the pit to the slurry preparation system or returns it to the absorption tower.

[0003] For example: A desulfurization unit filter water pit is equipped with three filter water pit pumps of the same model and power for drainage of the filter water pit. The specific operation mode is that when the filter water pit liquid level is high, the filter water pit pump is started, and when the filter water pit liquid level is low, the filter water pit pump is stopped. Ensure that the pit liquid level is always lower than the overflow level. Since the filter water pit water comes from the filtered water of multiple vacuum belt conveyors, the flow rate of filtered water is closely related to the number of vacuum belt conveyors started. The more vacuum belt conveyors in operation, the more filtered water, and vice versa. Therefore, when the filter water pit liquid level reaches a certain level, starting a few filter water pit pumps can make the pit liquid level drop, which varies with the number of vacuum belt conveyors started. In this way, sometimes starting one pump can make the liquid level drop continuously, and sometimes two or even three pumps need to be started at the same time to meet the requirements of liquid level drop.

[0004] There are two general control methods for filtered water pit pumps at present. One is pure manual, which is to manually determine the start order of the filtered water pit pumps according to the change of filtered water flow, that is, which one to start first, which one to start later, how many to start in total, and when to stop, and then operate manually. Another method is to automatically start a filtered water pit pump according to the liquid level. As for which filtered water pit pump to start, it is achieved by selecting the input switch. Which switch is selected, which pump is put into operation, and then manually estimate which pumps need to be replaced according to the operation time of the equipment, and which pumps do not need to be put into automatic liquid level operation.

[0005] The two current control methods are: the first is purely manual operation control, which is cumbersome and labor-intensive. If you are not careful, it will cause the filter water pit to overflow. This method is very backward; the second method has made great progress compared to the first method, but it still requires manual selection of which pump to start. The pump that is not put into interlock start and stop will not run. This causes uneven pump operation time, with some pumps running for a long time and some pumps running for a short time, resulting in uneven service life of the filter water pit pump, which does not meet the operation management requirements of regular equipment rotation.

[0006] Therefore, the current operation control of multiple filtered water pit pumps is not automatic, not intelligent, and cannot automatically realize equipment rotation operation. Summary of the invention

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0025] The present embodiment provides a filter water pit pump operation control method for periodic rotation control of multiple filter water pit pumps. Since the filter water pit pump generally takes no more than one hour to start and stop each time, this type of equipment is not suitable for equipment rotation operation during stop switching during operation. Instead, an overall balance of the operation time of each pump should be achieved through an intelligent control strategy to achieve intelligent automatic rotation control of the filter water pit pump. The number of the above-mentioned filter water pit pumps can be set according to actual conditions. To facilitate the description of the scheme, the present embodiment mainly describes a system in which a filter water pit of a desulfurization device is installed with three filter water pit pumps of the same model and power for drainage of the filter water pit. Please refer to Figure 2 , Figure 2 A schematic diagram of a control system of a desulfurization device according to an embodiment of the present application is schematically shown. The method comprises the following steps: Step 210: During each rotation control, corresponding filtered water sump pumps are respectively set for each level of the preset multi-level stepped liquid level according to the preset equipment rotation principle, wherein the preset equipment rotation principle is to select a filtered water sump pump with a corresponding shutdown time from a set of candidate start-up pumps according to the level of the stepped liquid level, wherein the set of candidate start-up pumps includes a plurality of filtered water sump pumps that have been shut down; In this embodiment, the above-mentioned preset multi-level ladder liquid level can be divided according to the depth of the specific filter water pit. The smaller the liquid level value, the lower the level represented. For example: the depth of the filter water pit is generally about 3 meters. If it exceeds 3 meters, it will overflow from the pit, which seriously affects safe and civilized production, and it is necessary to strictly prevent overflow accidents. Therefore, the filter water pit pump must be started before the liquid level reaches 3 meters. Therefore, the pit liquid level can be divided into three levels of ladder liquid levels, namely the first level, that is, the high value H1=2.6 meters; the second level, that is, the high value H2=2.7 meters, and the third level, that is, the high value H3=2.8 meters. Among them, the first level has the lowest level and the third level has the highest level. According to different step liquid levels, the filter water pit pumps that need to be started corresponding to H1, H2, and H3 are intelligently and automatically selected.

[0026] The preset equipment rotation principle is to select a filtered water pit pump with a corresponding outage time from the alternative starting pump set according to the height of the step liquid level level, that is, the lower the step liquid level level, the filtered water pit pump with a longer outage time is selected.

[0027] The above-mentioned alternative starting pump set includes multiple out-of-service filtered water pit pumps, that is, the out-of-service filtered water pit pumps serve as alternative starting pumps in the alternative starting pump set.

[0028] It should be noted that, in theory, every pump can be used as an alternative starting pump, but there are some special reasons that prevent some pumps from being used as alternative starting pumps, so the alternative pumps must meet some conditions, including that the filtered water pit pump has stopped, the filtered water pit pump is in remote control, the filtered water pit pump is not suspended, the filtered water pit pump has no comprehensive faults, and the filtered water pump has been put into interlocking, etc. When a single pump cannot be put into operation due to a fault or other reasons, it can be flexibly withdrawn, the downtime of the pump that has been put into operation is automatically calculated, and an alternative selection is made. This has great adaptability to changing working conditions.

[0029] Taking #1 filter water pump, #2 filter water pump and #3 filter water pump as examples, the above three filter water pumps must meet the following conditions as alternative pumps: (1) The logic for #1 filter water pump to enter the timing standby mode requires the following conditions to be met at the same time: #1 filter water pump has stopped; #1 filter water pump is in remote control state; #1 filter water pump is not suspended; #1 filter water pump has no comprehensive fault; #1 filter water pump has been interlocked; (2) The logic for #2 filter water pump to enter the timing standby mode requires the following conditions to be met at the same time: #2 filter water pump has stopped; #2 filter water pump is in remote control state; #2 filter water pump is not suspended; #2 filter water pump has no comprehensive fault; #2 filter water pump has been interlocked; (3) The logic for #3 filter water pump to enter the timing standby mode requires that the following conditions are met at the same time: #3 filter water pump has stopped; #3 filter water pump is in remote control state; #3 filter water pump is not suspended; #3 filter water pump has no comprehensive faults; #3 filter water pump has been interlocked.

[0030] In some embodiments, according to the preset equipment rotation principle, corresponding filtered water pit pumps are respectively set for each level of the preset multi-level stepped liquid level, including the following steps: First, multiple filter water pit pumps are concentrated into a pool of candidate start-up pumps and sorted according to the length of outage to obtain a filter water pit pump sequence; In this embodiment, the filtered water pit pumps in the candidate start pump set are all out of service filtered water pit pumps, wherein the outage duration of the filtered water pit pump is counted from the time the pump stops. The above sorting can be sorted from long to short outage duration, or from short to long outage duration.

[0031] In some embodiments, the step of collecting multiple filtered water pit pumps as candidate start-up pumps and sorting them according to the length of downtime to obtain a filtered water pit pump sequence includes the following steps: In the first step, multiple filter water pit pumps are concentrated into a pool of candidate start-up pumps and sorted according to the length of shutdown to obtain an initial filter water pit pump sequence; The second step is to determine whether there are multiple filtered water pit pumps in the initial filtered water pit pump sequence with the same downtime; Step 3: When it is determined that there are multiple filtered water pit pumps with the same outage time in the candidate starting pump set, the filtered water pit pumps with the same outage time are sorted according to the length of operation time before the outage, so as to update the initial filtered water pit pump sequence and obtain the filtered water pit pump sequence; In the fourth step, when it is determined that there are not multiple filtered water pit pumps with the same downtime in the candidate starting pump set, the initial filtered water pit pump sequence is used as the filtered water pit pump sequence.

[0032] In this embodiment, during the specific implementation, there may be multiple situations where there are multiple pumps with the same outage duration. In this way, when sorting, the filtered water pit pumps with the same outage duration can be sorted according to the length of time they ran before the outage. For example, if the outage duration of #2 filtered water pump and #3 filtered water pump is the same, the length of time they ran before the outage can be further compared. If the running time of #2 filtered water pump before the outage is greater than the running time of #3 filtered water pump before the outage, then #3 filtered water pump is given priority. For example: In the above example, if starting one pump each time is sufficient, then three pumps can be randomly switched as alternatives for H1\H2\H3, avoiding the situation where a specific pump is started each time the H1 value is reached, while other pumps are not started. If two pumps need to be started to be sufficient, then start a selected backup pump at H1 value, and the liquid level continues to rise. When it reaches H2, start another selected backup pump. After that, the liquid level begins to drop, and finally reaches the lowest liquid level. The two pumps stop at the same time. After stopping, the H1\H2 backup pump selection is reset, and the backup pumps continue to be selected in chronological order. Obviously, in this case, the backup pump that was just used as H3 will automatically scroll to the H1 value backup pump. The H2 and H3 outage time is the same, and then the one with the longest running time before outage will be given priority as the H2 value backup pump, and the other one will be the H3 value backup pump.

[0033] By sorting the filtered water pit pumps with the same outage time according to the length of running time before the outage when there are multiple filtered water pit pumps with the same outage time in the alternative starting pump set, it can be avoided that the filtered water pit pumps can be sorted normally when the outage time is the same, thereby ensuring the correct selection of the corresponding filtered water pit pump.

[0034] Then, according to the levels of each step liquid level in the preset multi-step liquid level, the corresponding filtered water pit pumps are matched from the filtered water pit pump sequence in turn to obtain the filtered water pit pumps corresponding to each step liquid level; wherein, the lower the step liquid level in the preset multi-step liquid level, the longer the corresponding filtered water pit pump will be shut down.

[0035] In this embodiment, taking the above example as an example, the principle of equipment rotation is to first select the pump with the longest downtime as the H1 value, the pump with the second longest downtime as the H2 value, and the pump with the shortest downtime as the H3 value. After each pump stops, the timing starts, and the timing time is compared. The one with the longest timing time is given priority in the H1 value selection. Then, from the remaining two pumps, the pump with the longer downtime is selected as the H2 value. Finally, the remaining one is selected as the H3 value.

[0036] By sorting multiple filtered water pit pumps according to the length of outage, the corresponding filtered water pit pumps can be quickly matched from the filtered water pit pump sequence according to the levels of each step liquid level in the preset multi-step liquid level to obtain the filtered water pit pumps corresponding to each step liquid level.

[0037] In some embodiments, according to the preset equipment rotation principle, corresponding filtered water pit pumps are respectively set for each level of the preset multi-level stepped liquid level, including: First, determine whether the downtime of each filtered water pit pump in the candidate start-up pump set is the same; Then, when it is determined that the downtime of each filtered water pit pump in the candidate start-up pump set is different, according to the preset equipment rotation principle, corresponding filtered water pit pumps are respectively set for each level of the preset multi-level stepped liquid level; Then, when it is determined that the outage durations of the filtered water pit pumps in the candidate starting pump set are the same, corresponding filtered water pit pumps are set for each level of the preset multi-level stepped liquid level according to the preset matching rules.

[0038] In this embodiment, during the specific implementation, there may be a situation where all the filtered water pit pumps have the same downtime, that is, all the filtered water pit pumps are shut down at the same time. At this time, it is impossible to set the corresponding filtered water pit pumps for each level of step liquid level according to the downtime. A matching rule may be pre-set, and the corresponding filtered water pit pumps are set for each level of step liquid level according to the default matching rule. For example: In the above example, after the H1 value alternative is reset, the selection of alternative pumps is re-entered. Since the #1 filtered water pit pump has just stopped, it must be other pumps in terms of the length of the stop time. However, if it happens that the three pumps stop at the same time, that is, the downtime is the same, then the #1 pump can be selected as the alternative for the H1 value, the #2 pump can be selected as the alternative for the H2 value, and the #3 pump can be selected as the alternative for the H3 value.

[0039] By judging whether the outage durations of each filtered water pit pump in the alternative starting pump set are the same, when the outage durations of each filtered water pit pump are the same, according to the preset matching rules, corresponding filtered water pit pumps are set for each level of the preset multi-level stepped liquid level, so that it can be ensured that when the outage durations of each filtered water pit pump are the same, the corresponding filtered water pit pumps can be set normally for each level of the stepped liquid level.

[0040] Step 220: obtaining the current filtered water pit level in real time; In this embodiment, the current filtered water pit liquid level can be obtained through a sensor.

[0041] Step 230: Determine the step liquid level corresponding to the current filtered water pit liquid level according to the preset multi-step liquid level; In this embodiment, it is possible to determine which level of stepped liquid level the current filtered water pit liquid level belongs to based on the preset multi-level stepped liquid levels, that is, the stepped liquid level corresponding to the current filtered water pit liquid level.

[0042] In some embodiments, the step liquid level corresponding to the current filtered water pit liquid level is determined according to the pre-set multi-step liquid level, including: First, determine whether the current filtered water pit liquid level is greater than a preset interlock stop liquid level; In this embodiment, the preset interlock stop liquid level can be set according to the depth of the specific filter water pit. The interlock stop liquid level is lower than the step liquid level. When the liquid level is lower than the interlock stop liquid level, the filter water pit pump can be stopped.

[0043] Then, when it is determined that the current filtered water pit liquid level is greater than the preset interlock stop liquid level, the stepped liquid level corresponding to the current filtered water pit liquid level is determined according to the preset multi-step stepped liquid level.

[0044] In this embodiment, if the current filtered water pit liquid level is greater than the preset interlock stop liquid level, it means that it can be further determined which level of the stepped liquid level it belongs to.

[0045] Then, when it is determined that the current filtered water pit liquid level is not greater than the preset interlock stop liquid level, the currently running filtered water pit pump is stopped and the currently running filtered water pit pump is reset to obtain a stopped filtered water pit pump.

[0046] In this embodiment, if the current filtered water pit liquid level is not greater than the preset interlock stop liquid level, it means that the filtered water pit pump does not need to be operated, so the currently running filtered water pit pump is stopped and reset. The reset filtered water pit pump is reset as the stopped filtered water pit pump and serves as an alternative starting pump for the next rotation control.

[0047] In the above example, the specific reset conditions are: (1) H1 high value after pump selection reset condition: meet any of the following conditions: ① After #1 filter water pump is selected, the filter water pit liquid level reaches the H1 value and the interlock starts #1 filter water pump. When #1 filter water pump stops again, it resets.

[0048] ②After #2 filter water pump is selected, the liquid level in the filter water pit reaches the H1 value and the #2 filter water pump is started interlocked. When #2 filter water pump stops again, it is reset.

[0049] ③After #3 filter water pump is selected, the liquid level in the filter water pit reaches the H1 value and the #3 filter water pump is started interlocked. When the #3 filter water pump stops again, it will be reset.

[0050] (2) H2 high value after pump selection reset condition: meet any of the following conditions: ① (After #1 filter water pump is selected, the filter water pit liquid level reaches the H2 value to interlock and start #1 filter water pump, and reset when #1 filter water pump stops again) or (H1 resets after #1 filter water pump is selected); ② (After #2 filter water pump is selected, the filter water pit liquid level reaches the H2 value to interlock and start #2 filter water pump, and reset when #2 filter water pump stops again) or (H1 resets after #2 filter water pump is selected); ③ (After #3 filter water pump is selected, the filter water pit liquid level reaches the H2 value to interlock and start #3 filter water pump, and reset when #3 filter water pump stops again) or (H1 resets after #3 filter water pump is selected); (3) H3 high three-value pump selection reset condition: meet any of the following conditions: ① (After #1 filter water pump is selected, the filter water pit liquid level reaches the H3 value to interlock and start #1 filter water pump, and reset when #1 filter water pump stops again) or (H2 resets after #1 filter water pump is selected); ② (After #2 filter water pump is selected, the filter water pit liquid level reaches H3 value to interlock and start #2 filter water pump, and reset when #2 filter water pump stops again) or (H2 resets after #2 filter water pump is selected); ③ (After #3 filter water pump is selected, the liquid level in the filter water pit reaches the H3 value to interlock and start #3 filter water pump, and reset when #3 filter water pump stops again) or (H2 resets after #3 filter water pump is selected).

[0051] By judging whether the current filtered water pit liquid level is greater than the preset interlock stop liquid level, the currently running filtered water pit pump can be stopped and reset when the current filtered water pit liquid level is not greater than the preset interlock stop liquid level, and the stopped filtered water pit pump can be obtained as an alternative starting pump for the next rotation control, thereby ensuring the effectiveness of the rotation control.

[0052] Step 240: Based on the step liquid level corresponding to the current filtered water pit liquid level, control the operation of the corresponding filtered water pit pump.

[0053] In this embodiment, in the above example, as the filtered water flows into the pit, the liquid level of the filtered water pit gradually rises. When the liquid level is higher than the H1 value, the automatically selected filtered water pit pump is started. After the filtered water pit pump associated with H1 is started, if the liquid level continues to drop, when the liquid level reaches the interlock stop liquid level L1=0.8 meters, the pump is stopped; if the liquid level continues to rise, when the liquid level is higher than the H2 value, the automatically selected filtered water pit pump is started; if the liquid level continues to rise after starting the two pumps, when the liquid level is higher than the H3 value, the filtered water pit pump associated with H3 is started. When all three pumps are started, the liquid level will definitely continue to drop, and when it finally reaches the first value L1, all filtered water pit pumps are stopped.

[0054] During the above implementation process, at each rotation control, according to the preset equipment rotation principle, corresponding filtered water pit pumps are set for each level of the preset multi-level stepped liquid level, and the preset equipment rotation principle is to select a filtered water pit pump with a corresponding shutdown time from the alternative starting pump set according to the level of the step liquid level, and the alternative starting pump set includes multiple filtered water pit pumps that have been shut down; obtain the current filtered water pit liquid level in real time; determine the step liquid level corresponding to the current filtered water pit liquid level according to the preset multi-level stepped liquid level; and control the operation of the corresponding filtered water pit pump based on the step liquid level corresponding to the current filtered water pit liquid level. By setting the multi-level stepped liquid level, the filtered water pit pump that needs to be automatically started at each level is set, and according to the first-in-first-out principle, the pump ranking of each step liquid level can be intelligently scrolled to achieve normal control of the filtered water pit liquid level and intelligent periodic rotation operation of the filtered water pit pump.

[0055] It should be noted that the above-mentioned start rotation control can be started when any one of the filtered water pit pumps meets the preset filtered water pump interlock start condition. Specifically, in the above example, the intelligent automatic start of the step liquid level needs to meet any one of the following conditions: (1) #1 filter water pump interlock start condition: meet any of the following conditions: ① The switch is on and the liquid level reaches a high value, and pump #1 is automatically selected; ② The switch is on and the liquid level reaches the high second value, and pump #1 is automatically selected; ③ The switch is on and the liquid level reaches the high three values, and pump #1 is automatically selected; (2) #2 filter water pump interlock start condition: meet any of the following conditions: ④ The switch is on and the liquid level reaches a high value, and pump #2 is automatically selected; ⑤ The switch is on and the liquid level reaches the high second value, and the #2 pump is automatically selected; ⑥ The switch is on and the liquid level reaches the high three values, and the #2 pump is automatically selected; (3) #3 filter water pump interlock start condition, meet any of the following conditions: ⑦ The switch is on and the liquid level reaches a high value, and pump #3 is automatically selected; ⑧ The switch is on and the liquid level reaches the high second value, and pump #3 is automatically selected; ⑨ The on / off switch has been turned on and the liquid level has reached the high three values, and pump #3 is automatically selected.

[0056] Each filtered water pit pump can be equipped with an interlocking start-up switch. After being put into operation, the filtered water pit pump can be operated unattended and intelligently and automatically in rotation.

[0057] In some embodiments, the following steps are also included: First, determine whether the current rotation control time reaches the preset compensation period; Then, when it is determined that the current rotation control time reaches the preset compensation period, the filter water pit pumps are sorted according to the accumulated operation time of each filter water pit pump to obtain a compensation filter water pit pump sequence; Then, according to the level of each step liquid level in the preset multi-step liquid level, the corresponding filter water pit pump is matched from the said compensation filter water pit pump sequence in turn to obtain the compensation filter water pit pump corresponding to each step liquid level; wherein, the lower the level of the step liquid level in the preset multi-step liquid level, the shorter the accumulated running time of the corresponding compensation filter water pit pump; Then, based on the stepped liquid level corresponding to the current filtered water pit liquid level, the corresponding make-up filtered water pit pump is controlled to operate.

[0058] In this embodiment, when the filtered water pit pump does not meet the timing alternative conditions, such as failure, suspension, on-site, and manual interlock removal, this state often means that the pump is in a shutdown and maintenance state, which causes the filtered water pit pump to fail to participate in periodic operation, which violates the principle of regular rotation operation of equipment. Therefore, consider using periodic compensation, that is, judging whether the current rotation control time reaches the preset compensation cycle. If the compensation cycle is reached, the corresponding filtered water pit pump is matched according to the length of the cumulative running time. After the compensation filtered water pit pump is shut down, no reset rotation is performed until the maximum difference in the cumulative running time in the compensation filtered water pit pump sequence meets the preset time threshold, and the next rotation control is performed. It should be noted that the above-mentioned compensation cycle can be set according to actual conditions and can be multiple time periods.

[0059] In some embodiments, after the compensating filtered water sump pump stops operating, no reset rotation is performed, and the execution jumps to sort each filtered water sump pump according to the cumulative running time of each filtered water sump pump to obtain a compensating filtered water sump pump sequence, until the maximum difference in the cumulative running time in the compensating filtered water sump pump sequence meets the preset time threshold, and then the next rotation control is performed.

[0060] In this embodiment, after the compensation filter water pit pump stops operating, no reset rotation is performed, and each filter water pit pump is continuously sorted according to the accumulated running time of each filter water pit pump to obtain a compensation filter water pit pump sequence, and the corresponding filter water pit pump is matched from the compensation filter water pit pump sequence in turn according to the level of each level of the preset multi-level stepped liquid level to obtain the compensation filter water pit pump corresponding to each level of the stepped liquid level; wherein, the lower the level of the stepped liquid level in the preset multi-level stepped liquid level, the shorter the accumulated running time of the corresponding compensation filter water pit pump; based on the stepped liquid level corresponding to the current filter water pit liquid level, the corresponding compensation filter water pit pump is controlled to run. Until the maximum difference in the accumulated running time in the compensation filter water pit pump sequence meets the preset time threshold, the compensation control is jumped out and the next round of rotation operation is entered.

[0061] For example, you can set up two cycles for the difference compensation operation, one large cycle and one small cycle.

[0062] The small cycle is set to one day. Every 24 hours, the equipment operating time is accumulated and ranked. The H1 backup pump with the shortest operating time is selected first, the H2 backup pump with a shorter time is selected, and the H3 backup pump with the longest time is selected. After each pump is shut down, it will not be reset and rotated until the maximum and minimum operating time of the three pumps differ by no more than 1 hour, and the maximum compensation time is 6 hours. After 6 hours, it is considered that the compensation is completed and automatically enters the next automatic stage rotation control algorithm.

[0063] The large cycle is once a week. After each 168-hour operation cycle is completed, the compensation control will begin. The H1 backup pump with the shortest operating time will be selected first, the H2 backup pump with a shorter time will be selected, and the H3 backup pump with the longest time will be selected. After each pump is stopped, it will not be reset and rotated until the maximum and minimum operating time of the three pumps differ by no more than 3 hours. The compensation time is no more than 12 hours. After 12 hours, the compensation is considered to be completed and automatically enters the next automatic stage rotation control algorithm.

[0064] Due to various reasons, the trial operation time of each pump is uneven over a period of time. The compensation algorithm automatically calculates the pump that needs to be started to achieve balanced operation time of each pump. After the large and small compensation algorithms, the operation time of the filter water pit pump generally meets the equipment rotation operation requirements.
