Description

Technical Field

[0001] The present application relates to the technical field of condenser detection, and in particular to a condenser water injection leak detection device and method. Background Art

[0002] Condenser water injection leak detection is a conventional method for power plants to detect condenser leaks. After water injection leak detection, it can be determined that one or several of the condenser heat exchange tubes are leaking, thereby preventing the deterioration of the water vapor quality of the thermal system caused by condenser tube leakage, shortening the operation cycle of the fine treatment mixed bed, and severe corrosion, salt accumulation and scaling of thermal system equipment in a short period of time.

[0003] First, the desalted water used for condenser water injection and leak detection is usually discharged into the wastewater recovery pool for treatment as public waste, resulting in a large amount of cleaner desalted water being wasted; second, condenser water injection and leak detection requires manual removal of the desalted water leaked through the heat exchange tube bundle in the condenser circulating water pipeline to determine the location of the leaking tube bundle, which is inefficient and easy to miss, and there are safety hazards; finally, since small leaks are often difficult to detect and require manual waiting time is relatively long, it causes many inconveniences to the leak detection work.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0037] like Figure 1-Figure 9As shown, a condenser water injection leak detection device proposed in one embodiment of the present application includes a condenser, a water making workshop and a water supply system. The water making workshop here refers to the existing water making workshop as a conventional water making workshop of a thermal power plant. The workshop includes or is not limited to a dual-media filter, a self-cleaning filter, an ultrafiltration device, a reverse osmosis device, and an EDI desalination device, etc. The water supply system is used to inject desalted water into the condenser. The water supply system includes a desalted water recycling pipeline, a desalted water delivery pump and a desalted water tank; the desalted water making workshop is arranged on the water supply system, wherein the inlet of the water making workshop is connected to the outlet of the clean water delivery pump, and the outlet of the desalted water tank is connected to the water making workshop, which is used to purify the used desalted water and deliver it to the water supply system, and also includes:

[0038] A mobile frame 1, on which a control panel 2 is mounted;

[0039] The transmission mechanism 3 includes a driving carrier 301 vertically slidably mounted on the moving frame 1, a moving seat 302 horizontally slidably mounted on the driving carrier 301, the moving seat 302 is driven to move horizontally by the driving carrier 301, an infrared thermal imaging scanner 303 is mounted on the moving seat 302, and the infrared thermal imaging scanner 303 is electrically connected to the control panel 2;

[0040] The trigger driving mechanism 4 is installed on the moving frame 1 and is used to move the driving carrier 301. When the moving seat 302 moves to the maximum limit position on the driving carrier 301, the trigger driving mechanism 4 is used to drive the driving carrier 301 to move vertically downward for a fixed distance. That is to say, when in use, the liquid inside the condenser is first discharged, and then the desalted water is injected into the condenser through the water supply system. When the desalted water in the condenser reaches a certain liquid level, the moving frame 1 is then moved, and then the moving frame 1 is moved to the positions of multiple pipelines that need to be inspected. At this time, the infrared thermal imaging scanner 303 is located at the uppermost corner of the multiple pipelines. Then, the moving seat 302 is moved horizontally by the driving carrier 301. At this time, the infrared thermal imaging scanner 303 is in an open state. The moving seat 302 is moved to the maximum limit position. After that, the trigger mechanism will make the driving carrier 301 move vertically downward for a certain distance, thereby indirectly driving the infrared thermal imaging scanner 303 to move downward for a distance, that is, when the infrared thermal imaging scanner 303 moves to the far left or the far right, the infrared thermal imaging scanner 303 will move downward for a distance, so that multiple pipelines can be fully thermally scanned. The infrared thermal imaging scanner 303 draws a thermal imaging map and generates a pipeline plan at the junction of the condenser tube sheet through the control panel 2. When it is detected that the pipeline outlet temperature is higher than the temperature at the junction of the tube sheet, it is judged as an abnormal temperature, that is, there is a leak. Inspecting the pipeline in this way not only improves the work efficiency, but also can effectively prevent missed inspections during inspection, reduces the time of pipeline inspection, and is more convenient to use.

[0041] like Figure 1 As shown, in some embodiments, the driving carrier 301 includes a moving block 3011 symmetrically and vertically slidably mounted on the moving frame 1, and mounting plates 3012 are constructed on opposite sides of the two moving blocks 3011, and a guide rod 3013 and a reciprocating screw 3014 are horizontally mounted between the two mounting plates 3012, and the moving seat 302 is threadedly sleeved on the reciprocating screw 3014, and the guide rod 3013 passes through the moving seat 302, and a stroke adjustment component 5 is installed on the guide rod 3013 and the reciprocating screw 3014, and a motor for driving the reciprocating screw 3014 to rotate is installed on one of the mounting plates 3012, that is, the forward and reverse rotation of the reciprocating screw 3014 is controlled by the motor so as to drive the moving seat 302 to reciprocate horizontally, and the design of the stroke adjustment component 5 can control the reciprocating travel of the moving seat 302, so that when inspecting multiple pipelines at different positions of the condenser, it can effectively avoid the infrared thermal imaging scanner 303 spending too much time on moving, thereby further improving the inspection efficiency.

[0042] like Figure 1 As shown, in some embodiments, the stroke adjustment component 5 includes a driving plate 501 symmetrically arranged on the moving frame 1, a sliding cylinder 502 is vertically slidably installed on the driving plate 501, a connecting frame 503 is installed on the sliding cylinder 502, a limiting plate 504 is horizontally slidably installed on the connecting frame 503, an adjusting screw 505 is horizontally and rotatably installed on the connecting frame 503, the limiting plate 504 is threadedly sleeved on the adjusting screw 505, and the limiting plate 504 is slidably sleeved on the guide rod 3013 and the reciprocating screw 3014. When it is necessary to adjust the horizontal movement stroke of the moving seat 302, it is only necessary to screw the adjusting screw 505. Because the adjusting screw 505 is threadedly matched with the limiting plate 504, the rotation of the adjusting screw 505 can drive the moving seat 302 to move horizontally. Because the sliding cylinder 502 is vertically slidably installed on the driving plate 501, when the moving seat 302 moves downward, the limiting plate 504 will also move downward synchronously, without affecting the normal movement of the moving seat 302.

[0043] like Figure 1 and Figure 5As shown, in some embodiments, the driving plate 501 is horizontally slidably mounted on the mobile frame 1, a spring telescopic rod 6 is installed between the mobile frame 1 and the driving plate 501, the trigger driving mechanism 4 includes a transmission belt assembly symmetrically installed on the mobile frame 1, the transmission belt assembly includes two rotating rods 401 distributed up and down and rotatably mounted on the mobile frame 1, the two rotating rods 401 are sleeved with transmission wheels 402, a conveyor belt 403 is transmission-installed between the two transmission wheels 402, and two moving blocks 3011 are respectively connected to the two conveyor belts 403 vertically on the conveying plane A linkage 7 is installed on the moving frame 1, which acts on one of the rotating rods 401 of the two transmission belt assemblies. When the moving seat 302 pushes the limit plate 504, the rotating rod 401 is driven to rotate in one direction through the linkage 7. That is to say, when the moving seat 302 moves to the maximum limit position, it will push the limit plate 504 to move. The movement of the limit plate 504 causes the rotating rod 401 to rotate in one direction through the linkage 7, thereby realizing the automatic downward movement of the moving seat 302, reducing the residence time of the moving seat 302 and further improving the detection efficiency.

[0044] like Figure 1-Figure 6 As shown, in some embodiments, the linkage 7 includes a transmission gear 701 rotatably mounted on the rotating rod 401 through a one-way bearing, and a driving rack 702 is installed on each of the two driving plates 501. The two driving racks 702 are respectively used to mesh with the two transmission gears 701. That is to say, when the moving seat 302 moves and contacts the limit plate 504, the limit plate 504 will push the driving plate 501 to move, and the driving plate 501 will drive the driving rack 702 installed thereon to move when it moves. Because the driving rack 702 is meshed with the transmission gear 701, when the moving seat 302 pushes the driving plate 501 to move, , one of the rotating rods 401 will rotate, thereby realizing the movement of the conveyor belt 403, and then the moving block 3011 will indirectly drive the moving seat 302 to move downward, and no additional driving force is required to drive the moving seat 302 to move downward, which is more convenient to use. When the moving seat 302 is no longer in contact with the driving plate 501, the spring telescopic rod 6 will reset the moving rod of the mounting plate 3012. Because the transmission gear 701 is installed on the rotating rod 401 through a one-way bearing, the transmission wheel 402 will only idle at this time and will not drive the rotating rod 401 to rotate, thereby preventing the conveyor belt 403 from retreating.

[0045] like Figure 1 and Figure 6As shown, in some embodiments, a plurality of wedge-shaped grooves 8 are provided on the outer peripheral side of the conveyor belt 403, a connecting cylinder 9 is horizontally installed on the movable frame 1, and a wedge-shaped plate 10 for being inserted into the wedge-shaped groove 8 is slidably inserted at one end of the connecting cylinder 9, and a tightening spring piece 11 is installed between the wedge plate 10 and the connecting cylinder 9. The design of the wedge-shaped groove 8 and the wedge plate 10 can effectively prevent the rotating rod 401 from accidentally rotating due to excessive friction when the transmission gear 701 is idling, thereby playing a protective role. It should be noted that when the driving plate 501 is pushed so that the driving rack 702 moves to the maximum limit, the inclined surface of the wedge plate 10 contacts the inclined surface of the wedge-shaped groove 8 to disengage the wedge groove 8 and be inserted into another wedge groove 8, thereby preventing the rotating rod 401 from accidentally rotating.

[0046] like Figure 1-Figure 6 and Figure 8 As shown, in some embodiments, two driving plates 12 are symmetrically and horizontally slidably installed on the movable frame 1, a slot 13 is opened on the top of the connecting tube 9, one end of the two driving plates 12 passes through the two slots 13 and is connected to the wedge plate 10 respectively. When the movable seat 302 needs to be moved upward, the two trend plates are moved to make the wedge plate 10 disengage from the corresponding wedge groove 8, thereby releasing the constraint on the movement of the conveyor belt 403, so that the movable seat 302 can be moved upward.

[0047] like Figure 1 and Figure 6 As shown, in some embodiments, a pull plate 14 is vertically slidably installed on the mobile frame 1, and hinged rods 15 are symmetrically hinged on the pull plate 14. The free ends of the two hinged rods 15 are respectively hinged on the two driving plates 12. In other words, it is only necessary to pull the pull plate 14 downward, and the pull plate 14 will drive the two hinged rods 15 to move when it moves. Because the hinged rods 15 are hinged on the driving plate 12, the two driving plates 12 will be moved away from each other, so that it is more convenient for the staff to move the rod moving seat 302 upward, and it is more convenient to use.

[0048] like Figure 1As shown, in some embodiments, the spring telescopic rod 6 includes a mounting tube 601 horizontally mounted on the mobile frame 1, one end of the mounting tube 601 is open and a sliding ring groove 602 is provided in an annular manner at the open end, a movable plug sleeve 603 is threadedly inserted on the sliding ring groove 602, and a docking rod 604 is slidably inserted at one end of the movable plug sleeve 603, and a free end of the docking rod 604 is connected to the driving plate 501, one end of the docking rod 604 is located in the mounting tube 601 and is configured with a limiting block 605, and the end of the limiting block 605 away from the docking rod 604 is configured with a blocking rod 606 that abuts against the bottom end of the mounting tube 601, and a limiting block 605 is installed between the limiting block 605 and the mounting tube 601. There is a connecting spring 607, and the design of the baffle 606 plays a resetting role. When the baffle 606 contacts the bottom end of the mounting tube 601, it indicates that the driving rack 702 is moved to the initial position, and twisting the movable sleeve 603 can adjust the moving stroke of the limit block 605 in the mounting tube 601, thereby indirectly increasing the moving stroke of the driving rack 702. When inspecting different types of condensers, it can effectively control the downward moving distance of the movable seat 302, thereby ensuring that the infrared thermal imaging scanner 303 detects more accurately and preventing the infrared thermal imaging scanner 303 from repeatedly scanning and affecting subsequent thermal imaging patterns.

[0049] like Figure 1-Figure 9 As shown, a condenser water injection leak detection method comprises the following steps:

[0050] S1: drain the liquid inside the condenser, and then inject desalted water into the condenser through the water supply system. When the desalted water in the condenser reaches a certain liquid level, move the movable frame 1 so that the infrared thermal imaging scanner 303 faces the upper corner of the condenser heat exchange tube;

[0051] S2: Rotate the two adjusting screws 505 to drive the two limiting plates 504 to move, thereby controlling the moving stroke of the moving seat 302, and then twist the moving sleeve 603 to adjust the moving stroke of the docking rod 604;

[0052] S3: Start the motor to drive the adjusting screw 505 to rotate, and control the adjusting screw 505 to reciprocate so that the moving seat 302 pushes the limit plate 504, and then the rotating rod 401 rotates unidirectionally, so that the infrared thermal imaging scanner 303 moves downward after moving to the maximum limit position, and then the infrared thermal imaging scanner 303 draws a thermal imaging map, and generates a tube bundle plane diagram at the junction of the condenser tube sheet through the control panel 2. When it is detected that the outlet temperature of the tube bundle is higher than the temperature at the junction of the tube sheet, it is judged as abnormal temperature, that is, there is a leak;

[0053] S4: The desalted water inside the condenser is transported to the water-stopping workshop for purification, and the purified desalted water is then transported to the water supply system.

[0054] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.

When the desalted water in the condenser reaches a certain liquid level, the movable frame (1) is then moved so that the infrared thermal imaging scanner (303) is facing the corner above the heat exchange tube of the condenser; S2: Rotate the two adjusting screws (505) to drive the two limit plates (504) to move, thereby controlling the moving stroke of the movable seat (302), and then twist the movable sleeve (603) to adjust the moving stroke of the docking rod (604); S3: starting the motor to drive the adjusting screw (505) to rotate, and controlling the adjusting screw (505) to rotate back and forth so that the moving seat (302) pushes the limit plate (504), thereby causing the rotating rod (401) to rotate unidirectionally, so that the infrared thermal imaging scanner (303) moves downward after moving to the maximum limit position, and then the infrared thermal imaging scanner (303) draws a thermal imaging map, and generates a tube bundle plane diagram at the junction of the condenser tube sheet through the control panel (2). When it is detected that the tube bundle outlet temperature is higher than the temperature at the junction of the tube sheet, it is determined to be an abnormal temperature, that is, there is a leak; S4: The desalted water inside the condenser is transported to the water-stopping workshop for purification, and the purified desalted water is then transported to the water supply system.
