Description

Technical Field

[0001] This utility model relates to the field of condenser descaling technology, and in particular to a descaling device for a power plant condenser. Background Technology

[0002] Condensers in power plants are crucial equipment for ensuring efficient power generation, reducing energy consumption, and maintaining unit stability in the power industry. Condenser operation can reduce operational defects caused by insufficient vacuum, poor heat exchange, and deterioration of condensate quality, maintaining the stable operating state of the turbine, power generation efficiency, and compatibility with the thermal system. Based on unit capacity, steam parameters, and cooling methods, condensers ensure the safety of the thermodynamic cycle under reasonable operating conditions. By scientifically controlling operating parameters and adopting efficient heat exchange technologies, the risk of performance fluctuations can be effectively reduced, ensuring the heat exchange effect of the condenser and the unit's operational performance in the power production chain.

[0003] Condensers in power plants are key equipment for ensuring the efficiency of the unit's thermal cycle. They are commonly used in the steam condensation and recovery stages of thermal and nuclear power plants. However, some existing condensers have integrated piping installations. Over time, the cooling water will accumulate biological sludge and scale, which can clog the pipes and reduce heat exchange efficiency. This leads to increased coal consumption and a sharp decrease in power generation. Traditionally, manual cleaning and maintenance are required, which is not only time-consuming and labor-intensive but also can shorten the equipment's lifespan due to pipe corrosion. In continuous production, if the pipes suddenly become blocked, it can cause a sudden increase in turbine exhaust pressure, leading to an emergency shutdown of the unit and increasing operation and maintenance costs. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a descaling device for power plant condensers, aiming to improve the problem of troublesome cleaning of pipes clogged with dirt in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a descaling device for a power plant condenser, comprising a chamber, a water pump fixedly connected to the bottom of the inner wall of the chamber, a conveying pipe connected to the left side of the water pump, an outer shell connected to the top of the conveying pipe, a fixing ring slidably connected to the inner wall of the outer shell, a slotted column fixedly connected to the inner wall of the fixing ring, a sliding groove formed on the outer wall of the slotted column, a retaining ring slidably connected to the inner wall of the sliding groove, a blade fixedly connected to the outer wall of the retaining ring, a scraper fixedly connected to the outer wall of the blade, a filter screen fixedly connected to the top of the inner wall of the outer shell, and a circulation mechanism fixedly connected to the inner wall of the chamber, the circulation mechanism being used to recycle the coolant used in the condenser.

[0006] As a further description of the above technical solution: The circulation mechanism has a partition, the outer wall of which is fixedly connected to the inner wall of the cabin. The inner wall of the partition has a water inlet channel. The bottom of the partition is connected to a three-way pipe, the bottom of which is connected to a converter. The left side of the converter is connected to a transport pipe, the left side of the transport pipe is connected to a connecting pipe, and the right side of the converter is connected to a drain pipe. The right side of the outer wall of the cabin is fixedly connected to a drain pool.

[0007] As a further description of the above technical solution: The bottom of the drainage pool is fixedly connected to a support block, and the top of the outer shell is connected to a water outlet pipe.

[0008] As a further description of the above technical solution: The bottom of the cabin is fixedly connected to multiple support columns, and the bottom of each support column is fixedly connected to a base.

The flow of coolant drives the blades, and the blades slide on the grooves opened in the slotted column. The dirt is removed by the scraper installed on the top of the blade. The filter screen can block the dirt scraped off by the scraper inside the outer casing, thereby removing the dirt in the pipe, effectively reducing the problem of frequent downtime for cleaning and reducing operation and maintenance costs.

[0014] 2. In this utility model, the heat of the steam in the device is removed by cooling water, causing the steam to condense into water. Water flows into the three-way pipe through the water inlet groove in the partition. Then the water is processed by the converter. The processed water flows into the connecting pipe from the transport pipe. The unprocessed wastewater can be discharged into the drainage pool through the drain pipe, thus realizing the recycling of cooling water. Attached Figure Description
