Description

Technical Field

[0001] This invention relates to the field of condenser cleaning technology, and more specifically, to a performance testing platform for condenser cleaning equipment. Background Technology

[0002] As a key heat exchange device in industrial systems such as thermal power generation and refrigeration, scale buildup inside the condenser can significantly reduce heat transfer efficiency, severely impacting the economic efficiency and safety of unit operation. Therefore, regularly cleaning the condenser piping using physical cleaning devices such as rubber balls and brushes, or chemical cleaning methods, has become an essential maintenance measure to ensure its efficient operation.

[0003] Currently, various condenser cleaning equipment are widely used in industrial sites. However, existing technical solutions have a significant drawback: the lack of an effective testing platform for scientifically and quantitatively evaluating their cleaning performance before installation and deployment. Equipment manufacturers and users typically have to select models based on theoretical parameters or past experience, and the final actual cleaning effect can only be verified after the equipment is installed in the condenser and put into operation.

[0004] This "install first, verify later" approach has led to numerous problems. If the cleaning equipment fails to perform as expected, it must be shut down for replacement or adjustment, directly causing production interruptions and resulting in significant economic losses. Furthermore, the repeated installation, disassembly, and testing processes consume considerable time and manpower, leading to low maintenance efficiency and potentially causing unnecessary mechanical damage to the condenser itself.

[0005] Therefore, the industry urgently needs a dedicated platform that can simulate actual working conditions and conduct pre-testing and evaluation of the performance of condenser cleaning equipment in a laboratory environment. This platform allows for objective comparison of the effectiveness of different cleaning technologies before equipment commissioning, optimizing equipment selection and parameter settings. This ensures cleaning effectiveness from the outset, avoids production risks and resource waste during on-site commissioning, and is of great significance for improving the foresight and scientific rigor of maintenance work.

[0006] To achieve the above goals, there is an urgent need to develop a performance testing platform for condenser cleaning equipment that can meet the aforementioned functions. The core issues to consider when developing this performance testing platform are as follows: The first is how to fully simulate actual working conditions while maximizing structural simplification; The second is how to evaluate the performance of different components or parameters of condenser cleaning equipment.

[0007] To solve the above problems, people have been seeking an ideal technological solution. Summary of the Invention

[0008] The purpose of this invention is to address the shortcomings of existing technologies by providing a condenser cleaning equipment performance testing platform that can fully simulate actual working conditions, has a simplified structure, and can perform simulation tests on components, operating parameters, and cleaning modes in condenser cleaning equipment.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A performance testing platform for condenser cleaning equipment includes a first condenser water chamber, a second condenser water chamber, heat exchange tubes, balance tubes, and a cleaning equipment simulation module. The heat exchange tube is connected between the first condenser water chamber and the second condenser water chamber. The first condenser water chamber and the second condenser water chamber are each detachably equipped with a nozzle installation station. The nozzle installation station is directly opposite the center position of the heat exchange tube to simulate the actual cleaning situation. The external branch water circuit of each nozzle installation station is combined and connected to the high-pressure flushing circuit of the cleaning equipment simulation module. The balance pipe is connected between the first condenser water chamber and the second condenser water chamber to simulate heat exchange tubes that have not been cleaned. The balance pipe is equipped with a flow regulating valve to regulate the flow rate of the balance pipe. The first condenser water chamber and the second condenser water chamber are connected to the water circulation loop in the cleaning equipment simulation module. Flow meters are installed on both the heat exchange tube and the balance tube.

[0010] In the proposed solution, the first and second condenser water chambers are used to simulate the water chamber structure at both ends of the condenser. Heat exchange tubes are used to simulate the heat exchange tubes to be cleaned, and balance tubes are used to simulate the heat exchange tubes that have not been cleaned. A cleaning equipment simulation module is used to simulate the cleaning equipment. By limiting the parameters of the heat exchange tubes to match the actual heat exchange tube parameters, and by adjusting the flow rate of the balance tube, the operating environment is made closer to the actual operating conditions, thus realizing the simulation of the condenser operating environment. The nozzle installation station is used to test the cleaning performance of different nozzles, and the flow meter is used to monitor the flow parameters under operating conditions.

[0011] As described above, the first condenser water chamber, the second condenser water chamber, the heat exchange tubes, and the balance tubes are all transparent pipes. This allows for a direct view of the internal cleaning fluid flow process, facilitating technicians in obtaining real-time cleaning data.

[0012] Based on the above, the diameter of the balancing tube is larger than that of the heat exchange tube. Since the balancing tube is used to simulate the remaining heat exchange tubes that have not participated in the cleaning process, and the number of these tubes is much larger than the number of heat exchange tubes being cleaned, its diameter is set to be larger to facilitate simulation.

[0013] Based on the above, the number of heat exchange tubes is ≥2, and the increase in the number is used to simulate the cleaning situation in a multi-path case.

[0014] Based on the above, the cleaning equipment simulation module includes a water tank, a high-pressure water pump, a three-way valve, a rubber ball transceiver, a rubber ball pump, and a reversing four-way valve; The first outlet of the water tank is connected in sequence to the high-pressure water pump and the first port of the three-way valve through a pipeline. The remaining two ports of the three-way valve are respectively connected to the external branch water circuits of the nozzles in the first condenser water chamber and the second condenser water chamber to form the high-pressure flushing circuit. The second outlet of the water tank is connected in sequence to the launching chamber of the ball launcher and the ball pump via a pipeline. The outlet of the ball pump is connected to the first port of the reversing four-way valve. The second and third ports of the reversing four-way valve are respectively connected to the first condenser water chamber and the second condenser water chamber to form the water circulation loop. The fourth port of the reversing four-way valve is connected to the receiving chamber of the ball launcher.

[0015] This simulation module can simulate two working conditions: forward flushing and directional flushing, to achieve simulation of different modes. At the same time, by controlling the parameters of launching and receiving balls, pump operating parameters, flow parameters, etc., it can fully and flexibly simulate different operating parameters.

[0016] Based on the above, the high-pressure water pump, three-way valve, rubber ball transceiver, rubber ball pump, and reversing four-way valve are integrated on a modular bracket, and the water tank is integrated on this modular bracket or located on one side of the modular bracket. The integration is relatively high, facilitating relocation and control.

[0017] Based on the above, it also includes a gas storage tank, an angle seat valve, a check valve, and a gas-liquid mixer disposed between the rubber ball pump and the reversing four-way valve. The gas storage tank is provided with an inlet valve on its inlet side. The gas storage tank is connected to the first port of the gas-liquid mixer in sequence through the angle seat valve and the check valve. The second port of the gas-liquid mixer is connected to the outlet of the rubber ball pump. The outlet of the gas-liquid mixer is connected to the first port of the reversing four-way valve.

[0018] Based on the above, both the outlet and return water circuits of the water circulation loop are equipped with shut-off valves, and both outlets of the water tank are equipped with shut-off valves. These are used for water circuit control in different modes.

[0019] This invention has outstanding substantive features and significant progress compared to existing technologies. Specifically, this invention is designed based on the simulation of the condenser operating environment under clean conditions. Its core is the simulation of clean and unclean heat exchange tubes. By adjusting the flow rate of the balancing tube, the actual condenser environment can be adjusted and simulated, thereby improving the simulation similarity and flexibility of the device. Moreover, its structure is significantly simplified compared to the actual condenser. In addition, it can also simulate and test the components (such as nozzles), operating parameters, and cleaning modes in the condenser cleaning equipment, achieving comprehensive, multi-angle, and more flexible performance testing of the cleaning equipment.

[0028] The technical solution of the present invention will be further described in detail below through specific embodiments.

[0029] like Figures 1-7 As shown, a condenser cleaning equipment performance testing platform includes a first condenser water chamber 1, a second condenser water chamber 2, a heat exchange tube 3, a balance tube 4, and a cleaning equipment simulation module 10.

[0030] The heat exchange tube 3 is connected between the first condenser water chamber 1 and the second condenser water chamber 2. Both the first and second condenser water chambers 1 and 2 are detachably equipped with nozzle mounting positions for installing nozzles 5 of different specifications to simulate the cleaning performance of different nozzles 5. The nozzle mounting positions are directly opposite the center of the heat exchange tube 3 to simulate actual cleaning conditions. Normally, the nozzles 5 spray high-speed water flow towards the center of the opposite heat exchange tube 3 to clean it. In this embodiment, to achieve individual testing of each nozzle, a nozzle regulating valve 6 is installed on the external branch water line of each nozzle mounting position to control the flow of water from each nozzle 5. When the nozzle regulating valve 6 has flow rate regulation capability, it can also control the flow rate. The external branch water lines are combined and connected to the high-pressure flushing circuit of the cleaning equipment simulation module 10. Regarding the quantity, the number of heat exchange tubes is ≥2, and this expansion simulates cleaning scenarios under multi-path conditions.

[0031] The balance pipe 4 is connected between the first condenser water chamber 1 and the second condenser water chamber 2 to simulate heat exchange tubes that have not been cleaned. The balance pipe 4 is equipped with a flow regulating valve 7 to regulate the flow rate of the balance pipe 4. The first condenser water chamber 1 and the second condenser water chamber 2 are connected to the water circulation loop in the external cleaning equipment simulation module 10.

[0032] The balancing tube 4 is the core component for simulating the operating environment of the condenser. In actual condenser cleaning, there are thousands of heat exchange tubes. Each cleaning cycle involves cleaning one row, which typically contains several hundred tubes. The remaining heat exchange tubes do not participate in the cleaning process. To fully simulate the actual situation, it is necessary to consider the interference of the un-cleaned heat exchange tubes on the operating environment. Therefore, using a balancing tube 4 with a relatively larger diameter to simulate the un-cleaned heat exchange tubes, while also adjusting its flow rate to fully simulate the actual situation, is one of the core improvements that enable the implementation of this invention.

[0033] Both the heat exchange tube 3 and the balance tube 4 are equipped with flow meters 8, which can read the flow rate in real time and obtain operating parameters for technical personnel to analyze.

[0034] For ease of observation, in a preferred embodiment, the first condenser water chamber 1, the second condenser water chamber 2, the heat exchange tube 3, and the balance tube 4 are all equipped with transparent pipes that allow observation of the cleaning status. This allows for a direct view of the internal cleaning fluid flow process, facilitating technicians to obtain real-time cleaning information.

[0035] In this embodiment, the cleaning equipment simulation module 10 includes a water tank 101, a high-pressure water pump 102, a three-way valve 103, a rubber ball transceiver 104, a rubber ball pump 105, and a reversing four-way valve 106. The high-pressure water pump 102 can be a high-pressure multistage centrifugal pump.

[0036] The first outlet of the water tank 101 is connected in sequence to the first port of the high-pressure water pump 102 and the three-way valve 103 via a pipeline. The remaining two ports of the three-way valve 103 are respectively connected to the external branch water circuits of the nozzles 5 in the first condenser water chamber 1 and the second condenser water chamber 2 to form the high-pressure flushing circuit.

[0037] The second outlet of the water tank 101 is connected in sequence to the launching chamber of the ball launcher 104 and the ball pump 105 via a pipeline. The outlet of the ball pump 105 is connected to the first port of the reversing four-way valve 106. The second and third ports of the reversing four-way valve 106 are respectively connected to the first condenser water chamber 1 and the second condenser water chamber 2 to form the water circulation loop. The fourth port of the reversing four-way valve 106 is connected to the receiving chamber of the ball launcher 104.

[0038] To achieve the goal of platformization, the above-mentioned devices are fully integrated. The high-pressure water pump 102, three-way valve 103, rubber ball transceiver 104, rubber ball pump 105, and reversing four-way valve 106 are integrated on a modular bracket 11. The water tank 101 is integrated on the modular bracket 11 or set on one side of the modular bracket 11, so that its integration is relatively high and it is convenient to move and control.

[0039] To achieve full control of the water circuit, valves are installed in both the outlet and return water circuits of the water circulation loop, and valves are installed in both outlets of the water tank. In this embodiment, the valves are shut-off valves, used for water circuit control in different modes.

[0040] like Figure 6 As shown, to enrich the cleaning modes, this embodiment also adds an air tank 108, an angle seat valve 109, a check valve 110, and a gas-liquid mixer 111 disposed between the ball pump and the reversing four-way valve. An air inlet valve is provided on the air inlet side of the air tank 108, and the air outlet side of the air tank 108 is connected to the first port of the gas-liquid mixer 111 in sequence through the angle seat valve 109 and the check valve 110. The second port of the gas-liquid mixer 111 is connected to the outlet of the ball pump 105, and the outlet of the gas-liquid mixer 111 is connected to the first port of the reversing four-way valve 106.

[0041] The following is an explanation of how to simulate different working modes using the aforementioned testing platform: 1. For example Figures 4-6As shown, the nozzle flushing simulation test is as follows: Water from water tank 101 flows through the launching tank of ball transceiver 104 to ball pump 105, then through gas-liquid mixer 111 (no air is supplied at this time, only liquid passes through, check valve 110 is used to prevent liquid backflow into gas storage tank 108) to reversing four-way valve 106, and then to the first condenser water chamber 1. The water then flows from heat exchange tube 3 and balance tube 4 to the second condenser water chamber on the other side, then back to reversing four-way valve 106, and finally flows to ball transceiver 104. This circuit simulates condenser circulating water. At the same time, high-pressure water pump 102 delivers high-pressure water through three-way valve 103 to nozzle 5 directly opposite heat exchange tube 3 (nozzle regulating valve 6 controls the on / off state), realizing the flushing of heat exchange tube 3, and a flow meter 8 is set to record the flow rate before and after.

[0042] During backflushing, water enters from the second condenser water chamber and exits from the first condenser water chamber.

[0043] 2. For example Figures 4-6 As shown, a simulated ball cleaning test is conducted: An appropriate amount of balls are added to the launching tank of the ball launcher 104, and the filter screen of the launching tank is opened. Water from the water tank 101 passes through the launching tank, carrying the balls to the ball pump 105. It then passes through the gas-liquid mixer 111 (at this time, no air is supplied, only liquid and balls pass through) to the reversing four-way valve 106, and then to the first condenser water chamber 1. The water and balls then travel from the heat exchange tube 3 and the balance tube 4 to the second condenser water chamber 2 on the other side, then return to the reversing four-way valve 106, and finally flow back to the launching tank. At this time, the filter screen of the launching tank is open, and the water source mixing the balls re-enters the ball pump 105 to form a ball cleaning cycle. A check valve 107 is used to prevent balls from entering the water tank.

[0044] During backflushing, water enters from the second condenser water chamber and exits from the first condenser water chamber.

[0045] 3. For example Figures 4-6 As shown, the precision cleaning simulation test of the rubber balls is carried out as follows: Based on the rubber ball cleaning simulation test, the high-pressure water pump 102 is started. At this time, the high-pressure water pump 102 delivers high-pressure water through the three-way valve 103 to the nozzle facing the heat exchange tube 3 (the nozzle regulating valve controls the on and off), providing power to the rubber balls entering the heat exchange tube 3, making it easier for them to pass through the heat exchange tube 3. In addition, the flushing of the nozzle also has the function of guiding the rubber balls into the heat exchange tube 3.

[0046] During backflushing, water enters from the second condenser water chamber and exits from the first condenser water chamber.

[0047] 4. Chemical dosing and cleaning simulation test: Based on the nozzle flushing simulation test, chemicals are added to the launching tank to form chemical dosing and cleaning.

[0048] 5. For example Figure 7As shown, the air-water pulse cleaning simulation test: This test does not require starting the high-pressure water pump 102; it utilizes air-water pulses for cleaning. No rubber balls can be added in this test. Water from tank 101 travels through rubber ball transceiver 104 to rubber ball pump 105 and gas-liquid mixer 111. Compressed air from storage tank 108 forms pulses under the frequent opening and closing of angle seat valve 109 and reaches gas-liquid mixer 111. Gas and liquid mix here to form air-water pulses, which travel through reversing four-way valve 106 to the first condenser water chamber 1, performing air-water pulse cleaning on heat exchange tubes 3 and balance tubes 4. The pulses then return from the second condenser water chamber 2 to reversing four-way valve 106 and finally flow to rubber ball transceiver 104. An automatic vent valve is installed on the ball launching tank to prevent excessive pressure. In this test, a sample section can be set on balance tube 4 to observe the cleaning effect. Pressure gauges and flow meters are used to record pressure and flow rate.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
