Description

Technical Field

[0001] The present invention relates to the cleaning of condensers, and particularly to an optimized device for high-pressure water flushing of condensers. Background Art

[0002] During the overhaul of the condenser, it is found that scale forms on the inner wall of the cooling water pipes of the condenser (due to water quality deterioration). Although ordinary high-pressure water flushing can remove some scale, it takes a long time. Each single pipe has to be flushed back and forth at least more than 3 times before any effect can be barely seen, and the water pressure used has reached 700 kg, wasting a lot of manpower and material resources. More importantly, it seriously affects the overhaul schedule. Summary of the Invention

[0003] In view of the above problems, we have improved the traditional high-pressure water flushing equipment and proposed an optimized device for high-pressure water flushing of condensers.

[0004] The technical solution of the present invention: An optimized device for high-pressure water flushing of condensers, the device includes a high-pressure flushing device; the device further includes a scraper, and the scraper is installed on the high-pressure nozzle of the high-pressure flushing device; the scraper moves in the pipeline together with the high-pressure nozzle of the high-pressure flushing device, the high-pressure nozzle of the high-pressure flushing device flushes the inner wall of the pipeline, and the scraper scrapes the scale on the inner wall of the pipeline.

[0005] Further refining the above technical solution, a number of groups of ejection ports are evenly distributed on the outer periphery of the high-pressure nozzle of the high-pressure flushing device, and each ejection port sprays water backward and at an angle of 30° obliquely to flush the inner wall of the pipeline and make the high-pressure nozzle of the high-pressure flushing device move in the pipeline; the scraper is a rotating blade, and the rotating scraper is located behind each group of ejection ports, and its blades are evenly distributed on the outer periphery of the high-pressure nozzle of the high-pressure flushing device; each ejection port sprays water backward and at an angle of 30° obliquely to make the blades of the rotating scraper rotate. The rotating scraper is beneficial to scraping the scale on the inner wall of the pipeline; using the water sprayed by the high-pressure nozzle of the high-pressure flushing device as the power for the rotation of the blades of the rotating scraper, there is no need to additionally equip a motive mechanism, and the overall structure is simple.

[0006] Further refining the above technical solution, the rotation of the blades of the rotating scraper will also form a barrier, and the barrier has multiple backward-inclined angles. The barrier blocks the sprayed water and changes the spraying direction, so as to multi-angle flush the inner wall of the pipeline when the high-pressure nozzle of the high-pressure flushing device moves in the pipeline, and the effect is better.

[0007] Further refining the above technical solution, the number of blades of the scraper is at least 3.

[0008] To further refine the above technical solution, supports are provided both in front of and behind the high-pressure nozzle of the high-pressure flushing device. The support has at least 3 elastic support points, and the elastic supports of the support are evenly distributed around the high-pressure nozzle of the high-pressure flushing device. The high-pressure nozzle of the high-pressure flushing device moves in the pipeline, and the elastic support points of the front and rear supports support on the inner wall of the pipeline, ensuring the stability of the high-pressure nozzle of the high-pressure flushing device and its rotating blade during movement in the pipeline.

[0009] To further refine the above technical solution, the end of the blade of the scraper is serrated, which is more conducive to scraping the scale on the inner wall of the pipeline.

[0010] The advantages of the present invention are reasonable design and simple structure. By installing a scraper, when flushing the inner wall of the pipeline, the scale on the inner wall of the pipeline can be scraped with the assistance of the scraper, resulting in good cleaning effect and greatly improved cleaning efficiency. Description of the Drawings

[0011] Figure 1 It is a schematic structural diagram of an optimized device for high-pressure water flushing of a condenser.

[0012] In the figure, the rotating scraper 1, the high-pressure nozzle 2 of the high-pressure flushing device, the injection outlet 2-1, the support 3, and the pipeline 4. Detailed Embodiments

[0013] As shown in the figure, an optimized device for high-pressure water flushing of a condenser includes a high-pressure flushing device and a rotating scraper 1. The rotating scraper 1 is installed on the high-pressure nozzle 2 of the high-pressure flushing device. A number of groups of injection outlets 2-1 are evenly distributed around the high-pressure nozzle 2 of the high-pressure flushing device. The rotating scraper 1 is located behind each group of injection outlets 2-1, and its blades 1-1 are evenly distributed around the high-pressure nozzle 2 of the high-pressure flushing device. There are at least 3 blades 1-1 of the scraper. Supports 3 are provided both in front of and behind the high-pressure nozzle 2 of the high-pressure flushing device. The support 3 has 4 elastic support points, and the elastic supports of the support 3 are evenly distributed around the high-pressure nozzle 2 of the high-pressure flushing device. The end of the blade of the scraper is serrated. When the above-mentioned optimized device for high-pressure water flushing of a condenser is in use, the high-pressure nozzle 2 of the high-pressure flushing device is placed in the pipeline 4. The elastic support points of the front and rear supports 3 support on the inner wall of the pipeline 4. The high-pressure flushing device is started, and each group of injection outlets 2-1 sprays water backward at an angle of 30°, causing the high-pressure nozzle 2 of the high-pressure flushing device to drive the rotating scraper 1 to move forward in the pipeline, and at the same time causing the blades 1-1 of the rotating scraper to rotate. The high-pressure nozzle 2 of the high-pressure flushing device flushes the inner wall of the pipeline, and the rotating scraper 1 scrapes the scale on the inner wall of the pipeline. During the process, the rotation of the blades 1-1 of the rotating scraper will also form a barrier. The designed barrier has multiple backward-inclined angles. The barrier blocks the sprayed water and changes the spraying direction, flushing the inner wall of the pipeline from multiple angles.
