Description

Technical Field

[0001] This utility model belongs to the field of steam turbines, specifically relating to a high-efficiency heat exchange and cleaning device for steam turbine condenser tube bundles. Background Technology

[0002] A steam turbine is a rotary power unit that converts the thermal energy of steam into mechanical energy. It mainly drives the rotor to rotate by the impact of high-temperature and high-pressure steam on the blades and is widely used in thermal power plants, metallurgical industry, ship propulsion systems and other fields.

[0003] Current turbine condenser tube bundle cleaning devices generally have cleaning blind spots. Their cleaning operations can only be applied to the outer surface of the condenser tube bundle, making it difficult to reach impurities and dirt attached to the inner surface of the condenser tube bundle. This limits the cleaning process, resulting in poor cleaning effect, increased internal thermal resistance of the condenser tube bundle, and reduced heat exchange efficiency. Therefore, a high-efficiency heat exchange cleaning device for turbine condenser tube bundles is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency heat exchange and cleaning device for steam turbine condenser tube bundles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency heat exchange cleaning device for steam turbine condenser tube bundles, comprising a cleaning cylinder, three support legs fixedly connected to the bottom of the cleaning cylinder, an observation window fixedly connected to the surface of the cleaning cylinder, a sealing cover inserted and connected to the top of the cleaning cylinder, two lifting handles fixedly connected to the top of the sealing cover, a hydraulic cylinder fixedly connected to the top of the sealing cover, a pressure fixing ring fixedly connected to the telescopic end of the hydraulic cylinder, a flow dividing ring fixedly connected to the bottom inner wall of the cleaning cylinder, a flow dividing cavity opened inside the flow dividing ring, a condenser tube bundle located at the top of the flow dividing ring, a high-pressure water pump fixedly connected to the bottom of the cleaning cylinder, a flushing inner pipe fixedly connected to the top of the flow dividing ring, multiple high-pressure inner punches fixedly connected to the surface of the flushing inner pipe, several flushing outer pipes fixedly connected to the surface of the flow dividing ring, several high-pressure outer punches fixedly connected to the surface of the multiple flushing outer pipes, and two drain valve ports fixedly connected to the inside of the cleaning cylinder.

[0006] By setting the above structure, the clamping structure composed of the hydraulic cylinder and the pressure fixing ring can adaptively fix condenser tube bundles of different specifications, improve the applicability and flexibility of the turbine condenser tube bundle cleaning device for fixing condenser tube bundles of different specifications, and ensure its stability during high-pressure flushing. The cleaning water regulation mechanism of the diversion ring and diversion chamber can quickly guide the cleaning water to the flushing outer tube and flushing inner tube. With the high-pressure inner punch and high-pressure outer punch, the inner and outer surfaces of the condenser tube bundle can be efficiently cleaned, improving the overall cleaning effect of the condenser tube bundle. This ensures that the inner and outer surfaces of the condenser tube bundle can be kept as clean and tidy as possible, thus ensuring the heat exchange efficiency of the condenser tube bundle.

[0007] As a preferred embodiment, the bottom of the pressure-fixing ring is fitted against the top of the condenser tube bundle.

[0008] As a preferred embodiment, the water delivery end of the high-pressure water pump is fixedly connected to the bottom of the cleaning cylinder through the water distribution ring.

[0009] As a preferred embodiment, the water delivery end of the high-pressure water pump is connected to the diversion chamber.

[0010] As a preferred embodiment, the flushing inner tube is connected to the diversion chamber.

[0011] As a preferred embodiment, the plurality of the flushing outer tubes are respectively connected to the diversion cavity.

[0012] By incorporating a sealing cover and a hydraulic cylinder, the integrated design of the sealing cover and the hydraulic cylinder allows operators to simultaneously disassemble and assemble both components simply by operating the sealing cover. This avoids the cumbersome process of disassembling and assembling the traditional separate structure step by step, significantly improving work efficiency. At the same time, the integrated design makes the equipment space layout more compact, and while ensuring sealing performance, it also creates convenient conditions for the rapid storage and retrieval of condenser tube bundles of different specifications.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, through the inclusion of a hydraulic cylinder, a pressure fixing ring, a flow divider ring, a flow divider chamber, an outer flushing pipe, an inner flushing pipe, a high-pressure inner punch, and a high-pressure outer punch, along with a clamping structure composed of the hydraulic cylinder and the pressure fixing ring, can adaptively fix condenser tube bundles of different specifications. This improves the applicability and flexibility of the turbine condenser tube bundle cleaning device for fixing condenser tube bundles of different specifications, ensuring stability during high-pressure flushing. The cleaning water regulation mechanism of the flow divider ring and the flow divider chamber can quickly guide the cleaning water to the outer and inner flushing pipes. Combined with the high-pressure inner and outer punches, it can achieve efficient cleaning of the inner and outer surfaces of the condenser tube bundle, improving the overall cleaning effect of the condenser tube bundle and ensuring that the inner and outer surfaces of the condenser tube bundle remain as clean and tidy as possible, thus ensuring the heat exchange efficiency of the condenser tube bundle.

[0015] This utility model, by setting a sealing cover and a hydraulic cylinder, with the sealing cover and hydraulic cylinder integrated into one unit, allows the operator to complete the disassembly and assembly of both simultaneously by operating the sealing cover. This avoids the cumbersome process of disassembly and assembly required by traditional separate structures, significantly improving work efficiency. At the same time, the integrated design makes the equipment space layout more compact, and while ensuring sealing performance, it also creates convenient conditions for the rapid storage and retrieval of condenser tube bundles of different specifications.

Several flushing outer pipes 14 are fixedly connected to the surface of the flow-diverting ring 8. Several high-pressure outer punches 15 are fixedly connected to the surface of the multiple flushing outer pipes 14. The internal fixed connection of 1 has two drain valve ports 16.

[0023] The bottom of the pressure fixing ring 7 is attached to the top of the condenser tube bundle 10.

[0024] The water delivery end of the high-pressure water pump 11 passes through the cleaning cylinder 1 and is fixedly connected to the bottom of the diversion ring 8.

Subsequently, the high-pressure water pipe is connected to the high-pressure water pump 11, and the high-pressure water pump 11 is activated to deliver the cleaning water to the distribution chamber 9. The distribution chamber 9 can guide the cleaning water into the flushing inner pipe 12 and multiple sets of flushing outer pipes 14, and then spray it onto the inner and outer surfaces of the condenser tube bundle 10 through the high-pressure inner punch 13 and the high-pressure outer punch 15, respectively, to achieve efficient cleaning of the inner and outer surfaces.

[0030] After the cleaning operation is completed, the high-pressure water pump 11 is shut down, the hydraulic cylinder 6 is controlled to retract the pressure fixing ring 7, and the fixing of the condenser tube bundle 10 is released. The operator then opens the sealing cover 4 by pulling the handle 5 again, takes out the condenser tube bundle 10 whose inner and outer surfaces have been cleaned, and finally opens the two drain valve ports 16 to drain the wastewater after cleaning.
