TECHNICAL FIELD
[0001] The present application relates to a condenser with anti-blocking structure and an anti-blocking method thereof. BACKGROUND
[0002] The condenser is a key equipment in thermal power generation, nuclear power generation and many industrial steam power cycle systems, and its main function is to condense the exhausted steam from the steam turbine into water, thereby establishing and maintaining the required vacuum degree in the thermal cycle and improving the thermal efficiency of the unit.
[0003] During operation, the cooling medium flows in the condenser heat exchange pipe, and the outside of the pipe is the steam to be condensed. Suspended particulate matter, microorganisms, salt crystals, organic matter, silt and other impurities carried in the cooling medium are extremely easy to deposit, adhere, breed and scale on the inner wall of the heat exchange pipe, gradually forming a blockage. The scale layer has a low thermal conductivity, increasing the heat transfer resistance and seriously weakening the heat exchange capacity of the condenser, leading to an increase in the back pressure of the steam turbine, a decrease in the thermal efficiency of the unit cycle, and a significant waste of energy. And the deposited material reduces the effective flow area of the cooling medium, increases the system flow resistance, and causes the power consumption of the cooling water pump to rise, and in severe cases, it may even cause the pipeline to be completely blocked locally. At the same time, uneven heat exchange may cause local overheating or thermal stress, which will damage the service life of the equipment in the long run. In order to restore performance, frequent shutdown cleaning or maintenance is necessary, which not only increases labor and material costs, but also causes loss of valuable power generation time, affecting the overall availability and economy of the power plant.

There is also a method of adding chemical agents to dissolve or strip the scale, but there are problems such as high cost of reagents, possible corrosion of pipe materials, generation of harmful waste liquid for subsequent treatment, and environmental protection and equipment safety problems, which are not suitable as a normal anti-blocking means, and manual physical cleaning is time-consuming and labor-intensive.

[0030] In this invention, multiple cooling water pipes 11 are arranged in parallel inside the condenser shell 1. Tube plates 12 are fixed at both ends of the condenser shell 1 corresponding to the ends of the cooling water pipes 11. Positioning holes 15 matching the cooling water pipes 11 are opened on the tube plates 12. The two ends of the cooling water pipes 11 are connected to the inlet chamber 2 and the outlet chamber 3, respectively. Water pipes 4 are installed at the bottom of the inlet chamber 2 and the outlet chamber 3. A steam pipe 13 is provided at the top of the condenser shell 1, and a hot water well 14 is provided at the bottom, thus completing the assembly of the basic structure of the condenser.
[0031] Specifically, a mating ring 21 is pre-set at the connection end between the water inlet chamber 2 and the tube sheet 12, and multiple mounting holes 22 are opened on the mating ring 21. The mounting ring 54 on the outer periphery of the mounting plate 51 of the filter assembly 5 is precisely mated with the mating ring 21, so that the fastening holes 55 on the mounting ring 54 are aligned with the mounting holes 22, and bolts 56 are inserted to complete the fixation. Multiple filter holes 52 are opened on the mounting plate 51. The size of the filter holes 52 is larger than the positioning hole 15 and the cross-sectional size of the cooling water pipe 11. A filter screen 53 is installed in each filter hole 52, and a through hole 57 is opened in the middle of the filter screen 53.
[0032] Specifically, one end of the transmission rod 61 of the anti-clogging component 6 passes through the through hole 57 of the filter screen 53, and a rotating structure is assembled between the two to ensure that the transmission rod 61 can rotate flexibly. A helical blade 62 is fixed to the outer wall of the transmission rod 61. The transmission rod 61 with the helical blade 62 is inserted into the cooling water pipe 11, ensuring that the transmission rod 61 is located at the center of the cooling water pipe 11, and that the edge of the helical blade 62 does not contact the inner wall of the cooling water pipe 11. The overall length of the transmission rod 61 is at least longer than the overall length of the cooling water pipe 11, and its cross-sectional dimension is one-fifth of the inner diameter of the cooling water pipe 11. The other end of the transmission rod 61 extends through the water outlet chamber 3 to the outside and connects to the drive mechanism 63 outside the water outlet chamber 3, ensuring that multiple transmission rods 61 are linked with the drive mechanism 63 to achieve synchronous start and stop.
[0033] Specifically, the drive mechanism 63 is electrically connected to the control system. The control system has a pre-stored condenser operating parameter monitoring program, which can set an intermittent operation mode as needed, or collect operating parameters such as condenser vacuum and inlet / outlet water temperature difference to achieve intelligent start-stop control.
[0034] Specifically, the anti-clogging operation process is as follows: The filter assembly 5 is precisely aligned with the mounting ring 54 on the periphery of the mounting plate 51 and the docking ring 21 at the end of the water inlet chamber 2. Bolts 56 are used to pass through the fastening hole 55 and the mounting hole 22 to achieve a fixed assembly of the filter assembly 5 and the water inlet chamber 2. The transmission rod 61 is extended through the through hole 57 in the middle of the filter screen 53 into the cooling water pipe 11, ensuring that the rotational structure between the transmission rod 61 and the through hole 57 is properly assembled without any jamming. It is confirmed that the transmission rod 61 of the anti-clogging assembly 6 is located at the center of the cooling water pipe 11, the edge of the spiral blade 62 is not in contact with the inner wall of the cooling water pipe 11, and the length of the transmission rod 61 exceeds the overall length of the cooling water pipe 11. The end of the transmission rod 61 furthest from the filter assembly 5 is assembled with the drive mechanism 63, and the multiple transmission rods 61 are adjusted to ensure that they can operate synchronously with the drive mechanism 63. The condenser is started, and cooling water enters the water inlet chamber 2 through the water pipe 4, sequentially passing through… The filter screen 53 on the mounting plate 51 filters impurities in the cooling water through the filter holes 52 and filter screen 53. The filtered cooling water then enters the cooling water pipe 11 through the positioning holes 15 on the tube sheet 12, preventing impurities from entering the cooling water pipe 11 and causing blockage. The control system starts the drive mechanism 63, which drives multiple transmission rods 61 to rotate synchronously. The transmission rods 61 drive the spiral blades 62 to rotate inside the cooling water pipe 11. The rotation of the spiral blades 62 disturbs the sediment on the inner wall of the cooling water pipe 11 and agitates the water flow to prevent impurities in the cooling water from depositing on the pipe wall. The control system selects the operating mode of the drive mechanism 63: if intermittent operation is selected, a fixed start-stop interval can be set; if intelligent start-stop is selected, the control system collects the condenser operating parameters in real time. When the parameters are abnormal, the drive mechanism 63 is automatically started, and after completing the anti-blockage operation, it automatically stops, achieving anti-blockage without shutting down the machine.
[0035] In this invention, the filter assembly 5 in the water inlet chamber 2 directly intercepts impurities in the cooling water through the filter screen 53, preventing impurities from entering the cooling water pipe 11 at the source. The size of the filter hole 52 is larger than the positioning hole 15 and the cross-sectional size of the cooling water pipe 11, ensuring that the filtered water can smoothly enter the cooling water pipe 11 without affecting the water flow efficiency. The anti-clogging assembly 6 in the cooling water pipe 11 cleans the early scale buildup on the pipe wall and prevents new deposits from adhering through the rotation of the spiral blades 62. Moreover, the spiral blades 62 do not contact the pipe wall, avoiding the risk of pipe wall wear and component jamming, and ensuring the structural integrity of the cooling water pipe 11.
[0036] In this invention, the drive mechanism 63 can drive multiple transmission rods 61 to operate synchronously. Combined with the intermittent operation or intelligent start-stop function of the control system, anti-clogging cleaning can be completed without stopping the machine. This avoids the unplanned downtime losses caused by the need to stop the traditional condenser for cleaning due to blockage, and improves the continuous operation capability of the equipment.
[0037] In this invention, the transmission rod 61 is installed at the center of the cooling water pipe 11, and its cross-sectional size is only one-fifth of the inner diameter of the cooling water pipe 11. Furthermore, the spiral blade 62 does not contact the pipe wall, resulting in low occupancy of the cooling water flow channel, low water flow resistance, and ensuring the flow rate of cooling water, thus maintaining the high heat exchange efficiency of the condenser.
[0038] In this invention, the filter assembly 5 is fixed to the docking ring 21 of the water inlet chamber 2 by bolts 56, which is convenient for disassembly and assembly and facilitates regular cleaning or replacement of the filter screen 53; the anti-clogging component 6 is installed in conjunction with the filter assembly 5, and the rotation structure between the transmission rod 61 and the filter screen 53 is reasonably designed and operates reliably. The efficiency of component positioning and replacement during later maintenance is high, which reduces maintenance costs.
[0039] In this invention, the control system can flexibly select the operating mode according to actual needs. Intermittent operation can reduce energy consumption, while intelligent start-stop responds dynamically based on the condenser operating parameters, which not only ensures the anti-blocking effect but also avoids energy waste caused by the long-term continuous operation of the drive mechanism 63, thus adapting to the operating needs under different working conditions.
[0040] This invention reduces the corrosion and wear of core components such as cooling water pipes 11 and tube sheets 12 caused by impurities and scale buildup, extending the service life of the equipment and reducing the consumption and replacement frequency of spare parts. Simultaneously, it maintains the high efficiency of the condenser's heat exchange, avoiding increased coal or steam consumption due to decreased heat exchange efficiency, thus improving the overall economic efficiency of operation.
[0041] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

Confirm that the transmission rod (61) of the anti-clogging component (6) is installed in the center of the cooling water pipe (11), the edge of the spiral blade (62) on the outer wall of the transmission rod (61) does not contact the inner wall of the cooling water pipe (11), and the overall length of the transmission rod (61) is at least longer than the overall length of the cooling water pipe (11). The end of the transmission rod (61) away from the filter component (5) extends through the water outlet chamber (3) to the outside and is assembled with the drive mechanism (63) to ensure that multiple transmission rods (61) are linked and cooperated with the drive mechanism (63). S3. Start the condenser. After the cooling water enters the inlet chamber (2), it is filtered for impurities through the filter holes (52) on the mounting plate (51) and the filter screen (53) inside the holes. The filtered cooling water enters the cooling water pipe (11) through the positioning hole (15) on the tube sheet (12). The filter screen (53) intercepts the impurities carried by the cooling water, preventing impurities from entering the cooling water pipe (11) and causing blockage. S4. The drive mechanism (63) is started by the control system. The drive mechanism (63) drives multiple transmission rods (61) to operate synchronously. The transmission rods (61) drive the spiral blades (62) on their outer walls to rotate inside the cooling water pipe (11). The rotational disturbance of the spiral blades (62) is used to clean the sediment and disturb the water flow inside the cooling water pipe (11) to prevent impurities from being deposited during the flow of cooling water inside the cooling water pipe (11). S5. The control system, which is electrically connected to the drive mechanism (63), selects the operating mode of the drive mechanism (63) according to the actual operating requirements. It can control the drive mechanism (63) to operate intermittently, or collect the condenser operating parameters by the control system and intelligently control the start and stop of the drive mechanism (63) according to the changes in the operating parameters, so as to realize the non-stop anti-blocking operation.
