Description

Technical Field

[0001] The invention belongs to the field of direct air cooling units in the thermal power generation industry, and relates to a spraying, cleaning and wastewater recovery system, method, equipment and medium. Background Art

[0002] In direct air-cooled units, the air-cooled condenser is the core component of the entire air-cooled island operation, affecting the thermal efficiency of the thermal power generating unit. The heat exchange tube bundle of the air-cooled condenser is exposed to the atmospheric environment and is contaminated by dust, pollen, catkins and other impurities in the air, which affects the heat exchange efficiency, increases the back pressure of the unit, and ultimately affects the economic operation of the unit. In addition, when the outdoor temperature is high, even if the air-cooled fan is running at the maximum frequency, the high temperature of the heat exchange tube bundle affects the heat exchange effect, increases the back pressure of the unit, and increases the power consumption rate of the plant. The heat exchange tube bundle needs to be sprayed and cooled to improve the heat exchange efficiency and improve the economic operation of the power plant. Therefore, it is very necessary for thermal power plants to spray and cool the heat exchange tube bundle of the air-cooled condenser and clean and dedust it according to the actual operation and temperature and other conditions.

[0003] In the current spraying and cleaning process, a large amount of water is required, and the waste water from spraying and cleaning flows directly to the ground without being collected and utilized, resulting in a waste of water resources. At the same time, spraying or cleaning is judged by manual operation experience, and is not automatically performed according to the actual situation of the unit, resulting in delayed spraying and cleaning maintenance of the unit, affecting the economic efficiency of the unit operation. Secondly, cleaning is usually performed manually, which is labor-intensive and has low work efficiency. Finally, when operating in winter, when the outdoor temperature is low, the specific location of the frozen heat exchange tube bundle cannot be accurately located, resulting in untimely anti-freezing measures leading to freezing and cracking of the heat exchange tube bundle. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a spraying, cleaning and wastewater recovery system, method, equipment and medium. The system, method, equipment and medium can automatically start and stop the comprehensive spraying mode, fixed-point spraying mode and cleaning mode of the air-conditioning condenser according to the weather and the condition of the unit, saving manpower, effectively solving the problem of heat exchange efficiency caused by high surface temperature and dust on the heat exchange tubes of the air-conditioning condenser, and ensuring the economical operation of the unit; at the same time, the spraying and cleaning wastewater can be recovered to save water resources; in addition, the heat exchange tube bundle can be accurately located to issue a low temperature warning.

[0005] To achieve the above-mentioned purpose, the present invention discloses a spraying, cleaning and wastewater recovery system, including a condenser heat exchange tube bundle, a thermal imaging dual-spectrum network intelligent camera, a water collecting plate, a wastewater output pipeline, a desalted water pipeline, an electric three-way valve, a pipeline mixer and a drug dissolving box;

[0006] A mobile cleaning device is installed on the outside of the condenser heat exchange tube bundle. The thermal imaging dual-spectrum network intelligent camera is facing the condenser heat exchange tube bundle. Two water distribution pipes are installed on the mobile cleaning device. The first water distribution pipe is installed with a cooling nozzle, and the second water distribution pipe is installed with a flushing nozzle.

[0007] The water collecting plate is located below the heat exchange tube bundle of the condenser, and a water retaining cloth is arranged on the water collecting plate. The outlet of the water collecting plate is connected to the wastewater output pipe via the wastewater collecting tank and the wastewater collecting pipe, the outlet of the desalted water pipe is connected to the first opening of the electric three-way valve via the desalted water frequency conversion pump, the second opening of the electric three-way valve is connected to the first water distribution pipe, the second opening of the electric three-way valve is connected to the inlet of the pipeline mixer, the outlet of the drug dissolving box is connected to the inlet of the pipeline mixer via the drug dosing frequency conversion pump, and the outlet of the pipeline mixer is connected to the second water distribution pipe.

[0008] Furthermore, a track is provided on the outer side of the condenser heat exchange tube bundle, and the mobile cleaning device is located on the track.

[0009] Furthermore, it also includes a fixed pole, and a thermal imaging dual-spectrum network smart camera is installed on the fixed pole.

[0010] Furthermore, it also includes a pressure gauge and a weather thermometer. The control cabinet is connected to a mobile cleaning device, a water collecting plate, a thermal imaging dual-spectrum network intelligent camera, a desalted water frequency conversion pump, a dosing frequency conversion pump, a pressure gauge and a weather thermometer.

[0011] Furthermore, the thermal imaging dual-spectrum network smart camera can move up and down within a range of 1 to 20 meters on the fixed pole and obtain the temperature and image of the condenser heat exchange tube bundle within a 360° range.

[0012] Furthermore, it also includes a steam main exhaust pipe, the outlet of which is connected to the condenser heat exchange tube bundle.

[0013] Furthermore, it also includes an air cooling fan, which is located below the condenser heat exchange tube bundle.

[0014] The present invention discloses a method for spraying, cleaning and wastewater recovery, comprising the following steps:

[0015] The back pressure of the unit is monitored in real time through a pressure gauge, the weather temperature is monitored in real time through a weather thermometer, and the temperature and image of the surface of the condenser heat exchange tube bundle are detected through a thermal imaging dual-spectrum network smart camera;

[0016] When the air temperature is ≥30℃ or the back pressure is ≥30KPa or the thermal imaging dual-spectrum network intelligent camera detects that the temperature in 30% of the area of ​​the entire condenser heat exchange tube bundle is ≥60℃, the spray mode is entered. At this time, the desalted water frequency conversion pump is started, and the desalted water flows through the pipeline to the mobile cleaning device, and then sprays out from the cooling nozzle to cool the condenser heat exchange tube bundle, and then flows downstream along the condenser heat exchange tube bundle to the wastewater collection tank, and finally gathers in the wastewater collection pipe and is discharged;

[0017] When the back pressure is less than 30KPa and the air temperature is less than 30℃ and the temperature in less than 30% of the area of ​​the entire condenser heat exchange tube bundle is ≥60℃, the desalted water variable frequency pump will be stopped. After the spraying stops, during the operation of the unit, when the thermal imaging dual-spectrum network intelligent camera collects the temperature of a certain heat exchange tube bundle in the condenser heat exchange tube bundle greater than 70℃ or the collected image shows that the dust is greater than 1m 2 When the temperature of the condenser heat exchange tube bundle to be sprayed is less than 60°C or the collected image of the condenser heat exchange tube bundle is a clean picture, the desalted water variable frequency pump is controlled to stop;

[0018] When the weather temperature is ≥20℃ and the thermal imaging dual-spectrum network intelligent camera collects dust images of the condenser heat exchange tube bundle, the cleaning mode is started. At this time, the desalted water passes through the desalted water frequency conversion pump and the pipeline mixer, and then passes through the mobile cleaning device and is sprayed out from the flushing nozzle. The agent enters the pipeline mixer through the dosing frequency conversion pump. At the same time, the water collecting plate changes from the open ventilation state to the closed water collecting state, and the waste water after flushing is collected in the wastewater collection tank and finally gathered in the wastewater collection pipe. When the image of the condenser heat exchange tube bundle changes to the cleaning screen, the desalted water frequency conversion pump and the dosing frequency conversion pump are stopped, and the water collecting plate changes from the closed water collecting state to the open ventilation state.

[0019] When the weather temperature is ≤2℃ or the temperature of the condenser heat exchange tube bundle is less than 25℃, the frozen condenser heat exchange tube bundle will be located based on the images and temperature collected by the thermal imaging dual-spectrum network intelligent camera and a low temperature warning will be issued.

[0020] The present invention discloses a computer device, comprising a memory, a processor and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the steps of the spraying, cleaning and wastewater recovery method are implemented.

In addition, when the weather temperature is ≤2°C or the temperature of the condenser heat exchange tube bundle is less than 25°C, the frozen condenser heat exchange tube bundle is located according to the picture and temperature collected by the thermal imaging dual-spectrum network intelligent camera and a low temperature warning reminder is issued, so as to accurately locate the heat exchange tube bundle and issue a low temperature warning.

[0050] The spraying, cleaning and wastewater recovery method of the present invention comprises the following steps:

[0051] When the air-cooled unit is running at high temperature in summer, the hot steam in the steam main exhaust pipe 1 flows through the condenser heat exchange tube bundle 2, and then is cooled by the air-cooling fan 3 from bottom to top. After cooling, the hot steam condenses into water in the condenser heat exchange tube bundle 2. Due to the high temperature in summer, the heat exchange efficiency of the condenser heat exchange tube bundle 2 is low, causing the back pressure of the air-cooled condenser to increase, affecting the economic efficiency of the unit operation. The back pressure of the unit is monitored in real time by the pressure gauge 16, and the weather temperature is monitored in real time by the weather thermometer 17. The range of the back pressure of the air-cooled condenser measured by the pressure gauge 16 is 0 to 100Kpa; the range of the weather temperature measured by the weather thermometer 17 is -60℃ to 100℃; the thermal imaging dual-spectrum network intelligent camera 9 detects the temperature and image of the surface of the condenser heat exchange tube bundle 2, and the temperature range is -40℃ to 450℃.

[0052] When the air temperature is ≥30℃ or the back pressure is ≥30KPa or the thermal imaging dual-spectrum network intelligent camera 9 detects that the temperature in 30% area of ​​the entire condenser heat exchange tube bundle 2 is ≥60℃, the atomization spray mode is automatically turned on. At this time, all condenser heat exchange tube bundles 2 start to spray at the same time, and the desalted water frequency conversion pump 11 is started. The flow range of the desalted water frequency conversion pump 11 is 0-200t / h. The flow rate of the desalted water in the spray mode is 50t / h-200t / h. The desalted water flows through the pipeline to the mobile cleaning device 4 and is sprayed from the cooling nozzle 5. The atomized particle size of the cooling nozzle 5 is ≤80μm. The water flow rate of the atomized spray is small and is not enough to penetrate the condenser heat exchange tube bundle 2. It flows downstream along the condenser heat exchange tube bundle 2 to the wastewater collection tank 19, and finally converges in the wastewater collection pipe 20 and is discharged.

[0053] When the back pressure is less than 30KPa and the air temperature is less than 30℃ and the temperature in 30% of the area of ​​the entire condenser heat exchange tube bundle 2 is ≥60℃, the spraying will be automatically stopped and the desalted water variable frequency pump 11 will be stopped. After the spraying is stopped, during the operation of the unit, when the thermal imaging dual-spectrum network intelligent camera 9 collects the temperature of a heat exchange tube bundle in the condenser heat exchange tube bundle 2 greater than 70℃ or the collected image shows that the dust is greater than 1m 2 When the temperature of the condenser heat exchange tube bundle 2 to be sprayed is less than 60°C or the collected image of the condenser heat exchange tube bundle 2 is a clean picture, the fixed-point spraying is stopped and the desalted water variable frequency pump 11 is stopped.

[0054] When the weather temperature is ≥20℃ and the thermal imaging dual-spectrum network intelligent camera 9 collects the image of the condenser heat exchange tube bundle 2 as a dusty picture, the cleaning mode is started, and the condenser heat exchange tube bundle 2 is flushed face by face. After the desalted water passes through the desalted water variable frequency pump 11, the dosing variable frequency pump 13 and the pipeline mixer 14, it passes through the mobile cleaning device 4 and is sprayed from the flushing nozzle 6. The flow range of the dosing variable frequency pump 13 is 0-4t / h, the desalted water flow is 5-20t / h, and the dosing amount is 1-4t / h. The dosing agent is a liquid neutral descaling agent or a composite descaling agent. At the same time, the water collection system is started. Under the corresponding position of the flushed condenser heat exchange tube bundle 2, the water collection plate 8 changes from an open ventilation state to a closed water collection state. The plate material of the water collection plate 8 is corrosion-resistant and frost-resistant carbon fiber, and the surface is a water-resistant, dust-resistant and antistatic nano-coating. The wastewater after flushing is collected in the wastewater collection tank 19 and finally gathered in the wastewater collection pipe 20. When the image screen of the condenser heat exchange tube bundle 2 on the control cabinet 18 changes to the cleaning screen, the cleaning mode is automatically turned off, the desalted water variable frequency pump 11 stops, the dosing variable frequency pump 13 stops, and the water collecting plate 8 changes from a closed water collecting state to an open ventilation state.

[0055] When the weather temperature is ≤2°C or the temperature of the condenser heat exchange tube bundle 2 is less than 25°C, the control cabinet 18 locates the frozen condenser heat exchange tube bundle 2 according to the image and temperature collected by the thermal imaging dual-spectrum network intelligent camera 9 and issues a low temperature warning reminder, so that the staff can take anti-freeze measures in time.

7. The spraying, cleaning and wastewater recovery system according to claim 1, characterized in that: It also includes an air cooling fan (3), which is located below the condenser heat exchange tube bundle (2).

8. A method for spraying, cleaning and wastewater recovery, characterized in that: The spraying, cleaning and wastewater recycling system according to claim 4 comprises the following steps: The back pressure of the unit is monitored in real time by a pressure gauge (16), the weather temperature is monitored in real time by a weather thermometer (17), and the temperature and image of the surface of the condenser heat exchange tube bundle (2) are detected by a thermal imaging dual-spectrum network intelligent camera (9); When the air temperature is ≥30°C or the back pressure is ≥30KPa or the thermal imaging dual-spectrum network intelligent camera (9) detects that the temperature in 30% of the area of ​​the entire condenser heat exchange tube bundle (2) is ≥60°C, the spray mode is entered, and the desalted water variable frequency pump (11) is started at this time. The desalted water flows through the pipeline to the mobile cleaning device (4), and then sprays out from the cooling nozzle (5) to cool the condenser heat exchange tube bundle (2), and then flows downstream along the condenser heat exchange tube bundle (2) to the wastewater collection tank (19), and finally gathers in the wastewater collection pipe (20) and is discharged; When the back pressure is less than 30KPa and the air temperature is less than 30°C and the temperature in 30% of the area of ​​the entire condenser heat exchange tube bundle (2) is greater than or equal to 60°C, the desalted water variable frequency pump (11) is stopped. After the spraying is stopped, during the operation of the unit, when the thermal imaging dual-spectrum network intelligent camera (9) collects the temperature of a heat exchange tube bundle in the condenser heat exchange tube bundle (2) greater than 70°C or the collected image shows that the dust is greater than 1m 2 When the temperature of the condenser heat exchange tube bundle (2) to be sprayed is less than 60° C. or the collected image of the condenser heat exchange tube bundle (2) is a clean image, the desalted water variable frequency pump (11) is controlled to stop; When the weather temperature is ≥20°C and the thermal imaging dual-spectrum network intelligent camera (9) collects an image of dust on the condenser heat exchange tube bundle (2), the cleaning mode is started.
