Description

Technical Field

[0001] This invention relates to the field of steam recovery and utilization technology, and specifically provides a device for recovering and utilizing spent steam from manganese sulfate concentration. Background Technology

[0002] The waste steam recovery and utilization device for manganese sulfate concentration is an energy-saving device that recovers and reuses waste heat and condensate from the waste steam generated during the manganese sulfate concentration process. However, the waste steam may carry trace amounts of salt, trace amounts of acid mist, and impurity ions such as calcium and magnesium from the manganese sulfate solution. If these impurities are recovered directly, they may adhere to the surface of the heat exchange equipment to form scale, affecting the heat transfer effect and potentially polluting the recovery water.

[0003] Patent CN 112857094 A discloses a waste heat recovery device for a steam boiler, comprising a recovery tank with two connecting pipes fixedly installed inside. A heat-conducting pipe is fixedly connected between the two connecting pipes. A cleaning component is movably mounted on the surface of the heat-conducting pipe. A driving component, including a fixed shell, is fixedly mounted at one end of the recovery tank. This invention uses heated air at the end of the heating pipe away from the fixed plate as a power source, causing smooth movement between the piston frame, piston cylinder, piston cover, first connecting rod, first fixed arm, second fixed arm, second connecting rod, hinged arm, and driven wheel. The driven wheel drives the driving arm and driving rod to rotate via a positioning rod, thereby causing the driving rod to drive a movable ring and a brush to clean the surface of the heat-conducting pipe through the driving frame, transmission rod, and fixed rod. This achieves the purpose of cleaning the surface of the heat-conducting pipe and improving the thermal energy utilization rate.

[0004] This application improves a waste heat recovery device for a steam boiler by using a drive rod to drive a moving ring and a brush to clean the surface of the heat-conducting pipe through a drive frame, transmission rod, and fixed rod. This achieves the purpose of cleaning the surface dirt of the heat-conducting pipe and improving the thermal energy utilization rate. However, when using this device, the internal steam temperature is too high, which causes the brush to soften, resulting in incomplete cleaning. Furthermore, the internal temperature is prone to uneven heating. Therefore, we propose a waste steam recovery device for manganese sulfate concentration. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This invention uses a scraping mechanism and a condensation mechanism to cool the manganese sulfate concentrated waste steam entering the outer casing through the air inlet. During cooling, condensate and dirt are generated. When the steam is delivered into the outer casing through the air inlet, a power fan transports the steam through the inside of the cooling pipe to the outside of the cooling pipe. Finally, the condensed gas is output through the exhaust port. During the condensation process, the dirt generated by the manganese sulfate concentrated waste steam adheres to the inner and outer surfaces of the cooling pipe. Then, a transmission mechanism drives the scraping mechanism and the condensation mechanism to operate simultaneously. The rotation of the first rotating rod drives the worm blade scraper to scrape off the dirt from the inner wall of the cooling pipe. At the same time, the ring gear drives the scraper blade to scrape off the dirt from the outer wall of the cooling pipe. Finally, a vibration filter collection mechanism filters and collects the condensate and scraped dirt.

[0018] 2. This invention uses a vibration filtration and collection mechanism to filter and collect the condensed water after scraping off dirt. The scraped condensed water and dirt fall above the filter plate and the guide plate. The first vibration gear drives the second vibration gear to rotate. When the second vibration gear rotates, it drives the second transmission rod and the second trapezoidal gear to rotate. The second trapezoidal gear drives the first trapezoidal gear to rotate. Then, the first trapezoidal gear drives the second rotating rod and the elliptical vibration tube to rotate. The rotating elliptical vibration tube can drive the filter plate to vibrate. The filter plate filters the condensed water into the first collection box. At the same time, the dirt filtered above the filter plate is transported into the second collection box through the vibration of the filter plate, thus achieving the effect of collecting dirt simultaneously.

Finally, the condensed gas is output through the exhaust port 8. During the condensation process, the dirt generated by the manganese sulfate concentrate waste steam will adhere to the inner and outer surfaces of the cooling pipe 304. Then, the transmission mechanism 4 drives the slag scraping mechanism 2 and the condensation mechanism 3 to operate simultaneously. The first rotating rod 301 rotates to drive the worm blade scraper 201 to scrape off the dirt from the inner wall of the cooling pipe 304. At the same time, the ring gear 202 drives the scraper blade 203 to scrape off the dirt from the outer wall of the cooling pipe 304.

[0035] The vibration filtration and collection mechanism 5 includes a fixed shell 7 fixedly connected to the bottom of the outer shell 1. A filter plate 501 and a guide plate 502 are rotatably connected inside the fixed shell 7. A first vibration gear 503 is rotatably connected inside the outer shell 1. A second transmission rod 504 is rotatably connected inside the fixed shell 7. A second vibration gear 505 is fixedly connected to the outer surface of the second transmission rod 504.

[0036] Furthermore, the scraped-off condensate and dirt fall above the filter plate 501 and the guide plate 502. The first vibrating gear 503 drives the second vibrating gear 505 to rotate. When the second vibrating gear 505 rotates, it drives the second transmission rod 504 and the second trapezoidal gear 511 to rotate. The second trapezoidal gear 511 drives the first trapezoidal gear 510 to rotate. Then, the first trapezoidal gear 510 drives the second rotating rod 507 and the elliptical vibrating tube 508 to rotate. The rotating elliptical vibrating tube 508 can drive the filter plate 501 to vibrate. The condensate is filtered into the first collection box 512 through the filter plate 501.

[0037] Working Principle: During cooling, condensate and dirt are generated. When the steam is delivered to the interior of the outer casing 1 through the air inlet 9, the power fan 306 transports the steam through the interior of the cooling pipe 304 to the exterior. Finally, the condensed gas is output through the exhaust port 8. During condensation, dirt generated from the manganese sulfate concentration vapor adheres to the inner and outer surfaces of the cooling pipe 304. The transmission mechanism 4 then drives the scraping mechanism 2 and the condensation mechanism 3 to operate simultaneously. The first rotating rod 301 rotates, driving the volute scraper 201 to scrape off the dirt from the inner wall of the cooling pipe 304. Simultaneously, the ring gear 202 drives the scraper 203 to scrape off the dirt from the outer wall of the cooling pipe 304. Finally, the vibration filter collection mechanism 5 filters and collects the condensate and scraped-off dirt. The condensate and dirt scraped off fall onto the filter plate 501 and the guide plate 502. The first vibrating gear 503 drives the second vibrating gear 505 to rotate. When the second vibrating gear 505 rotates, it drives the second transmission rod 504 and the second trapezoidal gear 511 to rotate. The second trapezoidal gear 511 drives the first trapezoidal gear 510 to rotate. Then, the first trapezoidal gear 510 drives the second rotating rod 507 and the elliptical vibrating tube 508 to rotate. The rotating elliptical vibrating tube 508 can drive the filter plate 501 to vibrate. The condensate is filtered into the first collection box 512 through the filter plate 501. At the same time, the dirt filtered above the filter plate 501 is transported into the second collection box 514 through the vibration of the filter plate 501, thus achieving the function of collecting dirt at the same time.
