[0035] Working principle:

[0036] During the condensation and reflux process of the high-temperature steam, the high-temperature steam is connected to the high-temperature steam discharge pipe 118 through the steam pipe, and then enters the space between the condensation inner pipe 106 and the condensation inner water pipe 115; the steam flows along the inner wall of the arc-shaped pipe, and after contacting the pipe wall, it condenses into water droplets due to the cold; these water droplets drip on the bottom of the condensation inner pipe 106 and the condensation inner water pipe 115, and then are discharged through the condensate discharge pipe 117;

[0037] At the same time, the cold water between the condensation outer water tank 101 and the condensation inner tube 106 is sent to the chiller 3 for compression through the circulation pump 2, and then enters the space between the condensation outer water tank 101 and the condensation inner tube 106 through the external cold water inlet pipe 104; this process helps to condense and cool the high-temperature steam from the outside; on the other hand, the condensation inner water pipe 115 sends cold water into the condensation inner water pipe 115 through the internal cold water inlet pipe 107 connected to the circulation pump 2, thereby realizing a secondary cooling treatment of the high-temperature steam from the inside to the outside;

[0038] The water source flowing inside the inner cooling water inlet pipe 107 will impact the cross plate 109, and then exert pressure on the transmission rod 110 in the middle of the cross plate 109 to make it rotate; the rotation of the transmission rod 110 will drive the gear 111 to rotate, and the gear 111 will mesh with the gear 2 112, thereby causing the gear 2 112 to rotate; the rotation of the gear 2 112 will drive the gear ring 113 to rotate, and the gear ring 113 will drive the inner scraper 114 to scrape the condensed water condensed on the pipe wall between the condensation inner water pipe 115 and the condensation inner pipe 106, which is conducive to the dripping and discharge of the condensed water;

[0039] The water source in the inner cooling water inlet pipe 107 impacts the cross plate 109, causing the transmission rod 110 to rotate, thereby driving the gear 1 111 and the gear 2 112 to rotate the gear ring 113; this rotation drives the inner scraper 114 to move along the pipe wall between the condensation inner water pipe 115 and the condensation inner pipe 106, scraping off the condensed water, ensuring that the condensed water can drip and be discharged smoothly; this mechanism effectively prevents the accumulation of condensed water on the pipe wall and improves the condensation effect;

[0040] In general, this high-temperature steam condensation and reflux system achieves efficient condensation and reflux of high-temperature steam through multiple cooling treatments and condensate scraping mechanisms; this not only improves the operating efficiency of the system, but also ensures the stability of steam condensation, providing reliable technical support for related industrial applications.
