Technical Field

Background technique

Nowadays, flue gas water extraction technology has been initially applied to large-scale thermal power generating units. This technology uses the saturated flue gas after desulfurization to cool and condense to recover condensate water as the raw water for boiler feed water of the generating unit and the process water source of the relevant desulfurization system, thereby reducing the external water supply of large-scale thermal power generating units and greatly reducing the consumption of natural water sources. Therefore, flue gas water extraction technology is conducive to energy conservation and environmental protection of thermal power generation, and its application prospects are very broad.

However, since the flue gas water lifting technology has only been preliminarily applied to large thermal power generating units, a feasible debugging method for the flue gas water lifting system has not yet been formed. As a result, the flue gas water lifting system cannot be operated in an optimal working condition and it is impossible to effectively detect whether there are abnormalities in the flue gas water lifting system, which is not conducive to the normal operation of the flue gas water lifting system and improving the working efficiency of the flue gas water lifting system, and further is not conducive to the normal operation of the thermal power units corresponding to the flue gas water lifting system.

Through the above steps, the operating current of the circulating water pump can be accurately and in real time detected, and the water pump valve can be adjusted in time to control the water pump flow when the operating current exceeds the limit, so that the circulating water pump will not fail due to overload operation, which is conducive to the normal commissioning process of the flue gas water lifting system and the normal commissioning of the subsequent flue gas water lifting system.

Exemplarily, the motor parameters include the operating current of the circulating water pump and the wind temperature of the circulating water pump motor, so the operating current of the circulating water pump and the wind temperature of the circulating water pump motor can be directly obtained according to the motor parameters. The wind temperature of the circulating water pump motor can be collected by a relevant temperature sensor and recorded by a relevant system, program or software.

Exemplarily, the bearing parameters include but are not limited to bearing vibration value, bearing temperature and bearing pressure, etc. Since they include bearing vibration value and bearing temperature, the bearing vibration value and bearing temperature can be directly obtained according to the bearing parameters.

Exemplarily, the water pump environmental parameters include but are not limited to circulating water pump pressure, circulating water pump leakage, and circulating water pump water quality. Since they include circulating water pump pressure and circulating water pump leakage, the circulating water pump pressure and circulating water pump leakage can be directly obtained based on the water pump environmental parameters. The water pump environmental parameters can be collected by relevant sensors and recorded by relevant systems, programs or software. For example, the circulating water pump leakage can be collected by relevant liquid leakage sensors and recorded by relevant systems, programs or software. The circulating water pump pressure can be collected by relevant hydraulic sensors and air pressure sensors and recorded by relevant systems, programs or software.

It should be noted that the specific method and content of obtaining motor parameters, bearing parameters and water pump environmental parameters can be determined by technical personnel in this field according to actual conditions. The above description is only an example and does not constitute a limitation thereto.

Exemplarily, the water pump operating conditions include a preset circulating water pump rated current, a rated motor wind temperature range, a rated bearing vibration value range, a rated bearing temperature range, a rated circulating water pump pressure range and a rated circulating water pump leakage range, so the preset circulating water pump rated current, the rated motor wind temperature range, the rated bearing vibration value range, the rated bearing temperature range, the rated circulating water pump pressure range and the rated circulating water pump leakage range can be obtained directly according to the water pump operating conditions.

For example, the specific implementation of the first alarm can be determined by those skilled in the art according to actual conditions, and the embodiments of the present invention do not limit this. For example, the first alarm can be, but is not limited to, sending a message such as "there is an abnormality in the operation of the circulating water pump, please shut down the circulating water pump in time for maintenance" to the staff or sounding a corresponding alarm sound.

Preferably, the water level of the expansion water tank can continue to be detected while the water pump is running, and when the water level is lower than the preset minimum standard water level, the valve opening of the circulating water pump can be increased to ensure that the water flow in the flue gas water lifting circulation system is stable and large enough so that the relevant flushing process in the subsequent steps can proceed normally.

Preferably, it is also possible to manually determine whether the circulating water pump has abnormal sounds, and to inspect and repair the water pump when the water pump has abnormal sounds.

Through steps S301 to S305, the granularity of the parameters related to the detection and judgment of the water pump operation condition can be refined, so that it is possible to more accurately judge whether the motor parameters, the bearing parameters of the circulating water pump during operation, and the water pump environmental parameters meet the preset water pump operation conditions, and thus it is possible to more accurately and quickly warn the staff when there are abnormalities in the water pump operation, so as to increase the probability that the water pump can be dealt with in a timely manner when the operation condition is abnormal, and thus effectively prevent the water pump from being further damaged and causing further economic losses to the flue gas water lifting system.

For example, the rated bearing vibration value range can be determined by those skilled in the art according to actual conditions, and the embodiments of the present invention do not limit this. For example, the rated bearing vibration value range depends on the model or type of the circulating water pump, and can be, but not limited to, [10 μm, 120 μm] or [5 μm, 80 μm], etc.

For example, the rated circulating water pump pressure range can be determined by those skilled in the art according to actual conditions, and the embodiments of the present invention do not limit this. For example, the rated circulating water pump pressure range depends on the model or type of the circulating water pump, and can be, but not limited to, [0.05MPa, 0.20MPa] or [0.07MPa, 0.25MPa], etc.

For example, the rated circulating water pump leakage range can be determined by those skilled in the art according to actual conditions, and the embodiments of the present invention do not limit this. For example, the rated circulating water pump leakage range depends on the model or type of the circulating water pump, and can be, but not limited to, 0 drops/minute to 100 drops/minute or 0 drops/minute to 30 drops/minute.

The above-mentioned water pump operating conditions further refine the granularity of judging whether the water pump operation is normal, thereby improving the accuracy of the judgment, and further helping to more accurately and quickly alert the staff when there are abnormalities in the water pump operation, so as to increase the probability that the water pump can be dealt with in a timely manner when the operation is abnormal, and thus effectively prevent the water pump from being further damaged and causing further economic losses to the flue gas water lifting system.

In an optional embodiment, it further comprises:

If so, give a third warning to the staff.

Exemplarily, the filter screens are respectively arranged at the water inlet and outlet of the circulating water pump, which may be, but not limited to, the filter screens are respectively arranged at the filter screen clamping grooves corresponding to the water inlet and outlet of the circulating water pump, wherein the filter screen may be, but not limited to, a filter screen with a hole size of 3 mm. It should be noted that the specific implementation method of respectively arranging the filter screens at the water inlet and outlet of the circulating water pump can be determined by those skilled in the art according to actual conditions, and the above description is only an example and does not constitute a limitation thereto.

Exemplarily, the pressure after the filter can be collected by, but not limited to, a relevant pressure sensor or pressure transmitter, etc. and recorded by a corresponding system, software or program, etc. It should be noted that the specific method for obtaining the pressure after the filter can be determined by those skilled in the art according to actual conditions, and the above description is only an example and does not constitute a limitation thereto.

For example, the third alarm can be, but is not limited to, sending a message such as "The pressure of the circulating water pump filter is too low, and the filter may be clogged, please check and clean it in time" to the staff or sounding a corresponding alarm sound.

Preferably, the water quality in the flue gas water extraction system can also be detected in real time by manual means or water quality detection sensors. When the water quality does not meet the preset water quality standards, the water color is obviously abnormal, or there are many impurities in the water, the circulating water pump is stopped and all the water in the flue gas water extraction system is discharged, and then the circulating water pump is restarted to extract clean water to refill the flue gas water extraction system, wherein the water flowing in the flue gas water extraction system can be but is not limited to desalted water. Among them, the water quality standards include but are not limited to turbidity standards, conductivity standards, and pH value standards. It should be noted that the preset water quality standards can be determined by those skilled in the art according to actual conditions, and the embodiments of the present invention do not limit this. It should be noted that the specific implementation method for detecting water quality and changing water can be determined by those skilled in the art according to actual conditions, and the above description is only an example and does not constitute a limitation on this.

Through the above steps, impurities with larger particles can be effectively filtered out to prevent them from clogging the circulating water pump and causing related faults, and the water quality can be effectively detected to prevent sewage that does not meet the water quality standards from corroding or clogging the relevant equipment of the flue gas water lifting system, thereby being more conducive to reducing the probability of failure of the flue gas water lifting system and enabling the flue gas water lifting system to operate in better working conditions, thereby improving the efficiency of the flue gas water lifting system debugging and operation.

In an optional embodiment, isolating the sector group of the cooling tower and the water pump comprises:

Closing the water inlet valve, water outlet valve and exhaust valve of the sector;

Short-circuit the water inlet pipe of the water lifter.

For example, the specific location and number of the water inlet gate, water outlet gate and exhaust gate of the sector can be determined by those skilled in the art according to actual conditions, and the embodiments of the present invention do not limit this.

Exemplarily, the short-circuiting of the water inlet pipe of the water pump may be, but is not limited to, short-circuiting the water inlet pipe of the water pump to the water outlet pipe or water reservoir of the water pump through a corresponding short-circuiting pipe, so that the water pump is bypassed. It should be noted that the specific implementation method of short-circuiting the water inlet pipe of the water pump can be determined by those skilled in the art according to actual conditions, and the above description is only an example and does not constitute a limitation thereto.

Exemplarily, after closing the water inlet gate, water outlet gate and exhaust valve of the sector, relevant auxiliary plugging plates or auxiliary flanges may be arranged near the water inlet gate, water outlet gate and exhaust valve of the sector to enhance the sealing when isolating the sector.

Exemplarily, the release of isolation of the sector group may be, but is not limited to, opening the water inlet gate, water outlet gate and exhaust gate of the sector, and correspondingly removing the relevant auxiliary plugging plate or auxiliary flange, etc. It should be noted that the specific implementation method of releasing the isolation of the sector group can be determined by those skilled in the art according to actual conditions, and the above description is only an example and does not constitute a limitation thereto.

Exemplarily, the release of the isolation of the water pump may be, but is not limited to, canceling the short circuit of the water inlet pipe of the water pump, etc. It should be noted that the specific implementation method of releasing the isolation of the water pump can be determined by those skilled in the art according to actual conditions, and the above description is only an example and does not constitute a limitation thereto.

Through the above steps, the strength and comprehensiveness of the isolation of the sector group of the cooling tower and the water pump can be improved, which is more conducive to preventing water from entering the sector group and the water pump of the cooling tower, thereby being more conducive to concentrating the water flow to flush the connecting pipes and the cooling triangle of the cooling tower, improving the flushing strength of the connecting pipes and the cooling triangle of the cooling tower alone, and more effectively preventing dirt from other equipment from flowing into the connecting pipes and the cooling triangle of the cooling tower during the flushing process.

In an optional embodiment, short-circuiting the outlet of the cooling triangle of the cooling tower includes:

Short-circuit the water inlet and return loop pipes of the lower header at the outlet of the cooling triangle.

Exemplarily, the short-circuiting of the inlet and return water loops of the lower header at the outlet of the cooling triangle may be, but is not limited to, short-circuiting the inlet and return water loops of the lower header at the outlet of the cooling triangle to the short-circuited pipe interface of the inlet pipe or outlet pipe of the water lifter, so that water can also flow to the inlet and return water loops of the lower header at the outlet of the cooling triangle, thereby enabling the lower header of the cooling triangle and its inlet and return water loops to be circulated and flushed.

Through the above steps, more water can flow to the cooling triangle of the cooling tower, thereby strengthening the flushing intensity of each component in the cooling triangle and improving the cleanliness of each component in the cooling triangle after flushing, which is indirectly beneficial to improving the debugging efficiency of the flue gas water lifting system.

In an optional embodiment, it further comprises:

After the outlet of the cooling triangle of the cooling tower is short-circuited so that the water flow pumped out by the circulating water pump can flush the connecting pipe and the cooling triangle,

The emergency drain pipe of the system is opened so that the water flow pumped out by the circulating water pump can flush the emergency drain pipe.

Exemplarily, the emergency drainage pipe of the system may be opened, but not limited to, a switch, valve or gate related to the emergency drainage pipe. It should be noted that the specific implementation of opening the emergency drainage pipe of the system can be determined by those skilled in the art according to actual conditions, and the above description is only an example and does not constitute a limitation thereto.

Preferably, after flushing the connecting pipes and cooling triangle of the cooling tower, the expansion water tank can also be manually cleaned to remove scale or other impurities in the expansion water tank, so that the expansion water tank will not be blocked.

Through the above steps, the emergency drainage pipe can also be flushed to make it clean and not be blocked by excessive dirt and impurities. Therefore, when the subsequent flue gas water lifting system needs emergency drainage during operation, the water can be quickly discharged through the emergency drainage pipe, which is more conducive to protecting the flue gas water lifting system and reducing the probability of failure or damage in an emergency.

In an optional implementation, as shown in FIG4 , the step of opening a target sector of the sector group and closing other sectors includes the following steps:

S401: Close the water inlet valve, exhaust valve and water outlet valve of the other sectors.

S402: Open the water inlet gate and the exhaust valve of the target sector, close the water outlet gate of the target sector, and close the exhaust valve of the target sector when water is detected to flow out of the exhaust valve of the target sector, so that the water flow can fill the target sector.

S403: Open the water outlet door of the target sector to allow the target sector to be flushed.

Exemplarily, the relevant principles of closing the exhaust valve of the target sector when water is detected to be flowing out of the exhaust valve of the target sector can be referred to the description of closing the exhaust valve of the circulating water pump when water is detected to be flowing out of the exhaust valve of the circulating water pump in the embodiments of the present invention, which will not be repeated here.

Exemplarily, the water outlet gate of the sector may be disposed at, but not limited to, the bottom of the sector.

Through the above steps, the target sector can be filled with water before being flushed, so that part of the dirt or impurities in the target sector can be dissolved in advance, and the water flow rate when flushing the target sector can be significantly increased. Therefore, the above steps can significantly improve the flushing intensity and flushing efficiency of the target sector, making the target sector cleaner after flushing, which is more conducive to the normal operation of the cooling tower sector when the subsequent flue gas water lifting system is put into operation.

In an optional implementation, the closing the target sector includes:

Close the water inlet valve, exhaust valve and water outlet valve of the target sector.

Exemplarily, a plurality of sectors in a cooling tower are connected in parallel to a cooling tower main pipe.

Through the above steps, all relevant passages of the target sector can be closed, increasing the probability that water cannot enter the target sector, thereby strengthening the closing effect of the target sector and allowing the water to concentrate on flushing other sectors, indirectly improving the flushing intensity and efficiency of other sectors.

In an optional embodiment, the sequentially filling a plurality of water pump pipes in the water pump with water comprises:

Selecting the water pump pipeline where the inlet of the water pump is located as the target water pump pipeline;

Close the water inlet valve, exhaust valve and outlet valve of other water pump pipelines;

Repeat the steps of opening the water inlet valve and the exhaust valve of the target water pumping pipeline, closing the water outlet valve of the target water pumping pipeline, and closing the exhaust valve of the target water pumping pipeline when water is detected to flow out of the exhaust valve of the target water pumping pipeline so that the water flow can fill the target water pumping pipeline, opening the water outlet valve of the target water pumping pipeline, and selecting the water pumping pipeline adjacent to the target water pumping pipeline as the target water pumping pipeline, until there is no adjacent water pumping pipeline to be selected.

Preferably, before the water flow enters the water pump, the inlet and outlet of the cooling tower can be short-circuited so that the water flow can directly reach the water pump, so that the water flow no longer consumes extra time passing through the cooling tower, thereby indirectly increasing the speed of flushing the water pump.

Preferably, the water pump includes a preset heat exchanger and related cooling pipes, the related pipes in the heat exchanger and the cooling pipes are connected to a cooling tower, and the water flowing out of the cooling tower can enter the related pipes of the heat exchanger and the cooling pipes respectively. The water flowing in the related pipes of the heat exchanger is used to directly cool the flue gas, and the water flowing in the cooling pipe is used to cool the water in the related pipes of the heat exchanger. The related pipes of the heat exchanger are arranged adjacent to the corresponding flue, and the cooling pipe is arranged adjacent to the corresponding heat exchanger related pipes. It should be noted that the specific structure of the water pump can be determined by those skilled in the art according to actual conditions, and the above description is only an example and does not constitute a limitation thereto.

Exemplarily, the water pump pipeline includes but is not limited to the water pipe of the heat exchanger in the water pump and other water pipes in the water pump. Correspondingly, the water pump pipeline where the inlet of the water pump is located includes but is not limited to the water pump pipeline where the inlet of the heat exchanger is located and the water pump pipeline where other water pump inlets are located. It should be noted that the specific implementation method of selecting the water pump pipeline where the inlet of the water pump is located as the target water pump pipeline can be determined by those skilled in the art according to actual conditions, and the above description is only an example and does not constitute a limitation thereto.

Exemplarily, the specific principle of closing the exhaust valve of the target water pumping pipe when water is detected to flow out of the exhaust valve of the target water pumping pipe can be referred to the description of closing the exhaust valve of the circulating water pump when water is detected to flow out of the exhaust valve of the circulating water pump in the embodiment of the present invention, which will not be repeated here.

Through the above steps, the water pump pipes can be filled with water in sequence, thereby increasing the water filling speed of the water pump, and the gas in each water pump pipe can be exhausted so that the water pump will not have air blockage during the water filling and subsequent flushing process, thereby indirectly increasing the subsequent flushing speed of the relevant pipes of the water pump. Moreover, filling the water pump pipes with water first and then flushing can significantly increase the water flow rate of flushing the water pump pipes in the subsequent steps, thereby increasing the flushing strength and flushing efficiency of flushing the water pump pipes, and then making the flushed water pump cleaner, which is conducive to the normal operation of the water pump during the subsequent flue gas water lifting operation.

In an optional embodiment, the opening of the water outlet door of the water lifter includes:

Open the water outlet valve of the water pump pipe where the outlet of the water pump is located.

Exemplarily, the water pump pipe where the outlet of the water pump is located includes, but is not limited to, the water pump pipe where the outlet of the heat exchanger in the water pump is located and the water pump pipes where other water pump outlets are located. It should be noted that the specific implementation method of opening the water outlet gate of the water pump pipe where the outlet of the water pump is located can be determined by those skilled in the art according to actual conditions, and the above description is only an example and does not constitute a limitation thereto.

Among them, other water filling pipes and water make-up pipes of the flue gas water lifting system are also flushed during the flushing of the circulating water pump, cooling tower and water lifter.

Through the above steps, all the water outlet gates of the water pump can be fully opened, thereby indirectly improving the comprehensiveness of flushing the water pump and making the flushed water pump cleaner and more suitable for use.

Exemplarily, the fan parameters include, but are not limited to, the fan operating current, fan rotation direction, fan vibration value, and fan temperature of the cooling tower, so the fan operating current, fan rotation direction, and fan vibration value can be directly obtained based on the fan parameters. Among them, the fan operating current can be obtained through, but not limited to, relevant ammeters or current sensors, etc. and recorded by relevant systems, programs, or software. The fan rotation direction can be obtained from the relevant operation records, operation logs, or operation status files of the corresponding systems, software, or programs. The fan vibration value can be collected by relevant vibration sensors and recorded by relevant systems, programs, or software, etc., or it can be determined by measuring the gap voltage between the voltage sensor and the fan.

It should be noted that the specific method and content of obtaining the fan parameters of the cooling tower can be determined by those skilled in the art according to actual conditions, and the above description is only an example and does not constitute a limitation thereto.

Exemplarily, the fan operating conditions include preset fan rated current, rated fan rotation direction and rated fan vibration value range at different speeds, so the preset fan rated current, rated fan rotation direction and rated fan vibration value range at different speeds can be directly obtained according to the fan operating conditions. Among them, the specific speed values of the different speeds can be determined by those skilled in the art according to actual conditions, and the embodiment of the present invention does not limit this. For example, the specific speed values of the different speeds can include but are not limited to 25% of the full load speed, 50% of the full load speed, 75% of the full load speed and 100% of the full load speed, etc.

Exemplarily, the number of the cooling towers may be but is not limited to one or more, preferably 6.

For example, the specific implementation of the second alarm can be determined by those skilled in the art according to actual conditions, and the embodiments of the present invention do not limit this. For example, the second alarm can be, but is not limited to, sending a message such as "There is an abnormality in the operation of the cooling tower fan, please shut down the corresponding cooling tower for maintenance" to the staff or sounding a corresponding alarm sound.

Preferably, it is also possible to manually determine whether the cooling tower has abnormal sounds, and to inspect and repair the cooling tower when the cooling tower has abnormal sounds.

Through steps S501 to S503, the granularity of the parameters related to the operation of the cooling tower fan can be refined, so that it is possible to more accurately judge whether the fan parameters meet the preset fan operating conditions, and then it is possible to more accurately and quickly warn the staff when there are abnormalities in the operation of the fan, so as to increase the probability that the fan can be dealt with in a timely manner when the operation is abnormal, and then it can effectively prevent the cooling tower from being further damaged and causing further economic losses to the flue gas water lifting system.

In an optional embodiment, the fan operating conditions include:

The fan operating current is less than or equal to the fan rated current;

For example, the rated fan vibration value range depends on the model or type of the cooling tower fan, and can be, but not limited to, [10 μm, 300 μm] or [5 μm, 150 μm], etc.

The above-mentioned fan operating conditions further refine the granularity of judging whether the fan operation is normal, thereby improving the accuracy of the judgment, and further helping to more accurately and quickly alert the staff when there are abnormalities in the fan operation, so as to increase the probability that the fan can be dealt with in a timely manner when the fan operation is abnormal, and further economic losses to the flue gas water lifting system can be effectively prevented from further damage to the fan.

In an optional embodiment, it further comprises:

When it is detected that the water quality of one or more of the circulating water pump, the connecting pipe, the cooling tower, the water pump and the water reservoir does not meet the preset water quality standard, a fourth alarm is issued to the staff.

The water quality sensors include, but are not limited to, turbidity sensors, pH sensors, and conductivity sensors. Correspondingly, the specific indicators of the detected water quality include, but are not limited to, the turbidity, pH value, and conductivity of water.

It should be noted that the specific types of water quality sensors, specific indicators of water quality detection, specific indicators of water quality standards and their specific preset values can be determined by those skilled in the art according to actual conditions. The above description is only an example and does not constitute a limitation thereto.

For example, the specific implementation of the fourth alarm can be determined by those skilled in the art according to actual conditions, and the embodiments of the present invention do not limit this. For example, the fourth alarm can be, but is not limited to, sending a message such as "the water quality of the flue gas water extraction system does not meet the standard, please deal with it in time" to the staff or sounding a corresponding alarm sound.

Through the above steps, the water quality of each device and pipeline in the flue gas water lifting system can be monitored comprehensively and accurately, and an alarm can be issued in time when the water quality does not meet the standard, so that the staff can stop the flue gas water lifting system and change the water in time, which is beneficial to prevent the relevant equipment and pipelines of the flue gas water lifting system from being corroded or blocked by sewage and causing malfunctions, thereby facilitating the flue gas water lifting system to operate under normal conditions during the debugging process and subsequent commissioning.

In an optional embodiment, the preset water quality standard includes:

The turbidity of water is less than or equal to the preset turbidity standard value;

The pH value of the water is within the preset pH standard range;

For example, the turbidity standard value can be determined by those skilled in the art according to actual conditions, and the present invention does not limit this. For example, the turbidity standard value can be, but is not limited to, 0.1 NTU to 1 NTU.

For example, the pH value standard range can be determined by those skilled in the art according to actual conditions, and the embodiments of the present invention do not limit this. For example, the pH value standard range can be, but is not limited to, [7, 9] or [6.5, 8], etc.

For example, the conductivity standard range can be, but is not limited to, [0.5uS/cm, 500uS/cm] or [50uS/cm, 1000uS/cm], etc.

The above-mentioned water quality standards further refine the granularity of judging whether the water quality in the flue gas water lifting system is normal, thereby improving the accuracy of the judgment, and helping to more accurately and quickly alert staff when the water quality is abnormal, so as to increase the probability that the water quality in the system can be dealt with in a timely manner when it is abnormal, and thus effectively prevent sewage from causing corrosion or blockage of related equipment or pipelines, thereby causing damage to the flue gas water lifting system.

In an optional embodiment, it further comprises:

When it is detected that the liquid level of the expansion water tank connected to the system is less than the minimum value of the preset liquid level standard range, increasing the water pump flow rate of the circulating water pump;

When it is detected that the liquid level of the expansion water tank connected to the system is greater than the maximum value of the liquid level standard range, the water pump flow rate of the circulating water pump is reduced.

Exemplarily, the liquid level of the expansion water tank may be detected by, but not limited to, a preset liquid level meter or liquid level sensor, and recorded by a corresponding system, software or program.

For example, the standard range of the liquid level can be determined by those skilled in the art according to actual conditions, and the embodiments of the present invention do not limit this. For example, the standard range of the liquid level can be, but is not limited to, [1.3 meters, 1.7 meters].

Exemplarily, increasing or decreasing the water pump flow of the circulating water pump may be achieved by, but not limited to, sending a control signal corresponding to the increase/decrease of the valve opening of the circulating water pump to the relevant system, program, software, etc., so that the relevant system, program, software, etc. controls the increase/decrease of the valve opening of the circulating water pump based on the corresponding control signal to increase/decrease the water pump flow. It should be noted that the specific implementation method for increasing or decreasing the water pump flow of the circulating water pump can be determined by those skilled in the art according to actual conditions, and the above description is only an example and does not constitute a limitation thereto.

Through the above steps, it is possible to accurately judge based on the liquid level of the expansion water tank whether the water flow in the flue gas water lifting system is too large to cause overload and damage to the flue gas water lifting system while meeting basic debugging and operating requirements, thereby timely increasing the water flow of the system when the water flow is too small and timely reducing the water flow of the system when the water flow is too large. Therefore, the water flow in the flue gas water lifting system is not too large to cause overload and damage to the flue gas water lifting system while meeting basic debugging and operating requirements, which is conducive to the operation of the flue gas water lifting system under normal conditions and improving the debugging efficiency of the flue gas water lifting system and the work efficiency during the later commissioning.

In a preferred embodiment, it further comprises:

After the flue gas water extraction system is debugged, put the flue gas water extraction system into operation:

The flue gas water lifting system is turned on and connected so that the water in the flue gas water lifting system flows normally and all equipment and components in the flue gas water lifting system enter working state.

Based on the operating parameters such as the inlet and outlet water temperatures of the mechanical ventilation cooling tower, adjust the number of activated sectors of the mechanical ventilation cooling tower and the cooling fan output (cooling fan speed).

Among them, for the filling and draining of water in the sectors, operating personnel are required to assist in the operation on site to prevent large-scale overheating or freezing of the sector radiator due to valve sticking and other reasons, and to be able to promptly discover and repair problems such as water leakage caused by poor sealing of related sectors.

After the flue gas water lifting and circulating water system is put into normal operation, the relevant parameters of the flue gas water lifting system are adjusted through relevant programs, software or systems based on the relevant system operating procedures.

It should be noted that the specific implementation method of the above-mentioned commissioning steps can be determined by those skilled in the art according to actual conditions, and the embodiments of the present invention do not limit this.
