Description

Technical Field

[0001] This utility model relates to the field of high-temperature calcium carbide liquid material processing technology, specifically a heat exchange device for high-temperature calcium carbide liquid material processing. Background Technology

[0002] In the field of calcium carbide chemical industry, the high-temperature precipitation process of calcium carbide liquid (mainly composed of CaC2 molten liquid or calcium carbide-containing suspension) is a key step in the production of products such as acetylene, PVC, and ferroalloys. This process requires heating the calcium carbide liquid to a specific temperature (usually 800-1200℃) to achieve material melting, reaction, or molding. As the core component for temperature control, the performance of heat exchange equipment directly affects product quality, production efficiency, and energy consumption.

[0003] Compared to existing technologies: In the traditional calcium carbide production process, if the equipment cannot achieve rapid cooling of the molten calcium carbide, the high-temperature material may remain in the heat exchange equipment for too long. In this case, the retention of high-temperature material will adversely affect subsequent material preparation and separation processes, thus affecting the smooth connection of these processes. Due to the poor connection of these processes, the turnover rate of the production line will be greatly reduced, thereby affecting the efficiency and output of the entire production process.

[0004] Meanwhile, in the traditional calcium carbide production process, the large amount of sensible heat contained in the high-temperature calcium carbide liquid is not effectively recovered and utilized. This sensible heat is usually directly discharged into the environment, resulting in a large amount of energy waste. This energy waste not only increases production costs but also has a negative impact on the environment. Therefore, how to effectively recover and utilize the sensible heat of the high-temperature calcium carbide liquid has become an urgent problem to be solved in the calcium carbide production process.

[0028] Example 1:

[0029] If existing traditional equipment cannot achieve rapid cooling of molten calcium carbide, the high-temperature material may remain in the heat exchange equipment for too long, affecting the connection of subsequent processes such as material preparation and separation, and reducing the turnover rate of the production line. In the traditional calcium carbide production process, the sensible heat of the high-temperature molten calcium carbide is not effectively recovered and utilized, resulting in energy waste. Please refer to [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 This utility model provides a technical solution: a heat exchange device for high-temperature calcium carbide liquid material making, including a heat exchange tank 1, a feed pipe connected to the top surface of the heat exchange tank 1, a collection hopper connected to the bottom surface of the heat exchange tank 1, a control device 2 on the left side of the heat exchange tank 1, a heat exchange mechanism 3 on the inner side of the heat exchange tank 1, and a scraping mechanism 4 below the heat exchange tank 1.

[0030] The heat exchange mechanism 3 includes a heat exchange section 31 and a transfer section 32;

[0032] The scraping mechanism 4 includes a scraping section 41 and a conveying section 42;

[0033] The conveying section 42 is located below the scraping section 41.

[0034] The heat exchange section 31 includes a portal plate 311, which is fixedly connected to the top surface of the heat exchange tank 1. A heat-insulating motor 312 is provided on the inner side of the portal plate 311, and the heat-insulating motor 312 is fixedly connected to the portal plate 311. The output end face of the heat-insulating motor 312 extends through to the inner side of the heat exchange tank 1, and the heat-insulating motor 312 is rotatably connected to the inner wall of the heat exchange tank 1. A roller 313 is provided on the output end face of the heat-insulating motor 312, and the roller 313 is fixedly connected to the heat-insulating motor 312.

[0035] A connecting pipe 314 is connected to the top surface of the drum 313. A rotary joint 315 is provided on the surface of the connecting pipe 314. The rotary joint 315 is rotatably connected to the connecting pipe 314. An oil inlet pipe 316 is connected to the top surface of the rotary joint 315. The oil inlet pipe 316 extends through to the top of the heat exchange tank 1. A connecting pipe 317 is provided on the left side of the oil inlet pipe 316. The connecting pipe 317 is connected to the drum 313. A rotary joint 318 is provided on the surface of the connecting pipe 317. A branch pipe 319 is connected to the top surface of the rotary joint 318. The branch pipe 319 extends through to the top of the heat exchange tank 1.

[0036] The transfer section 32 includes an oil outlet pipe 321, which is connected to the drum 313. A rotary joint 322 is provided below the oil outlet pipe 321 and is rotatably connected to the oil outlet pipe 321. An auxiliary pipe 323 is provided on the inner side of the rotary joint 322 and extends through to the left side of the heat exchange tank 1. A switch valve is provided on the left end face of the auxiliary pipe 323 and a circulation pipe 324 is provided on the left end face of the switch valve. A water tank 325 is provided on the surface of the circulation pipe 324 and extends through to the inner side of the water tank 325. The top end face of the circulation pipe 324 extends through to the top of the water tank 325.

[0037] The top surface of the circulation pipe 324 is connected to the extraction pipe 326, which is connected to the circulation pipe 324. The rear end surface of the extraction pipe 326 is connected to the pump 327, the top surface of the pump 327 is connected to the return pipe 328, and the bottom end surface of the return pipe 328 is connected to the branch pipe 319.

[0038] Furthermore, in this embodiment, through the heat exchange mechanism 3, the liquid lead alloy is introduced into the drum 313 via the oil inlet pipe 316 in the heat exchange section 31. The calcium carbide liquid is placed into the heat exchange tank 1 through the feed pipe. The heat-insulating motor 312 is started, driving the drum 313 to rotate. The rotation of the drum 313 causes the liquid lead alloy to circulate inside the drum 313. During the flow, the liquid lead alloy fully contacts the calcium carbide liquid, absorbing its heat. After absorption, the switch valve is opened, allowing the heat-absorbed liquid lead alloy to circulate freely. The gold is discharged from the drum 313 through the oil outlet pipe 321. The liquid lead alloy after absorbing heat enters the circulation pipe 324. When the liquid lead alloy flows in the circulation pipe 324, it exchanges heat with the water in the water tank 325. After the liquid lead alloy releases heat in the circulation pipe 324, it cools down. The pump 327 is started. The pump 327 draws the liquid lead alloy in the circulation pipe 324 and makes it enter the return pipe 328. The liquid lead alloy finally returns to the inside of the drum 313 through the return pipe 328 and the branch pipe 319, completing a heat exchange cycle.

[0039] Furthermore, in this embodiment, through the heat exchange mechanism 3, the oil inlet pipe 316 in the heat exchange section 31 allows liquid lead alloy to be fed into the drum 313 from the oil inlet pipe 316, and calcium carbide liquid to be fed into the heat exchange tank 1 through the feed pipe. This activates the heat insulation motor 312, which drives the drum 313 to rotate, causing the liquid metal to circulate inside the drum 313 and absorb the heat from the calcium carbide liquid. The liquid lead alloy that has absorbed the heat enters the circulation pipe 324 through the oil outlet pipe 321 after the switch valve is opened. At this time, the water tank 325 contains water, so the liquid lead alloy entering the circulation pipe 324 heats the water in the water tank 325. After the liquid lead alloy cools down, the pump 327 is activated. The pump 327 draws water from the circulation pipe 324 into the return pipe 328 and finally returns to the drum 313 through the branch pipe 319. This achieves rapid cooling and waste heat recovery of the calcium carbide liquid, thereby improving the heat exchange efficiency.

[0040] Example 2:

[0041] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 Furthermore, based on Embodiment 1, the scraping section 41 includes a heat insulation cylinder 411. Two heat insulation cylinders 411 are arranged at the front and rear. The heat insulation cylinders 411 extend through to the inner side of the heat exchange barrel 1. An auxiliary plate 412 is provided on the output end face of each heat insulation cylinder 411. The auxiliary plate 412 is fixedly connected to the heat insulation cylinder 411. An annular scraper 413 is provided on the inner side of the auxiliary plate 412. The annular scraper 413 is fixedly connected to the auxiliary plate 412.

[0042] The conveying unit 42 includes a conveying pipe 421, which is connected to a collection hopper. A U-shaped plate 422 is provided on the left side of the conveying pipe 421 and is fixedly connected to the conveying pipe 421. A motor 423 is provided on the inner side of the U-shaped plate 422 and is fixedly connected to the U-shaped plate 422. The output end of the motor 423 extends through to the inner side of the conveying pipe 421 and is rotatably connected to the conveying pipe 421. A spiral blade 424 is provided on the output end of the motor 423 and is fixedly connected to the motor 423.

[0043] Furthermore, in this embodiment, the scraping mechanism 4 utilizes the heat-insulating cylinder 411 in the scraping section 41. After the calcium carbide liquid exchanges heat with the liquid lead alloy in the roller 313 in the heat exchange tank 1, its temperature decreases and it gradually solidifies. The solidified calcium carbide liquid adheres to the outer surface of the roller 313, forming a solid layer. When there is solidified calcium carbide liquid on the surface of the roller 313, the heat-insulating cylinder 411 is activated, and the piston rod of the heat-insulating cylinder 411 extends, driving the auxiliary plate 412 and the annular scraper 413. The annular scraper 413 moves towards the surface of the drum 313 and closely adheres to the surface of the drum 313. The sharp edge of the scraper scrapes off the solidified calcium carbide liquid from the surface of the drum 313. The scraped solidified calcium carbide liquid falls off in the form of particles and falls into the collection hopper below and into the conveying pipe 421. The motor 423 is started, and the motor 423 drives the spiral blade 424 to rotate. The spiral blade 424 rotates in the conveying pipe 421, generating axial thrust, which conveys the solidified calcium carbide liquid particles in the collection hopper forward.

[0044] Furthermore, in this embodiment, the scraping mechanism 4 utilizes the heat-insulating cylinder 411 in the scraping section 41. When the calcium carbide liquid cools down, it solidifies and adheres to the surface of the roller 313. At this time, the heat-insulating cylinder 411 is activated, which drives the auxiliary plate 412 and the annular scraper 413 to scrape the surface of the roller 313. The scraped material falls into the conveying pipe 421 through the collection hopper. At this time, the motor 423 is activated, which drives the spiral blades 424 to convey the solidified particles. This achieves automatic cleaning of the roller surface and continuous processing of solidified calcium carbide liquid particles, improves heat exchange efficiency, and reduces manual intervention.

[0045] In use, liquid lead alloy is introduced into the drum 313 through the oil inlet pipe 316 in the heat exchange unit 31 via the heat exchange mechanism 3. Calcium carbide liquid is placed into the heat exchange tank 1 through the feed pipe. The heat-insulating motor 312 is started, driving the drum 313 to rotate. The rotation of the drum 313 causes the liquid lead alloy to circulate inside the drum 313. During the flow, the liquid lead alloy comes into full contact with the calcium carbide liquid, absorbing the heat from the calcium carbide liquid. After absorption, the switch valve is opened, allowing the heat-absorbed liquid to flow freely. Liquid lead alloy is discharged from drum 313 through oil outlet pipe 321. After absorbing heat, the liquid lead alloy enters circulation pipe 324. When the liquid lead alloy flows in circulation pipe 324, it exchanges heat with water in water tank 325. After releasing heat and cooling in circulation pipe 324, pump 327 is started. Pump 327 draws liquid lead alloy from circulation pipe 324 and sends it into return pipe 328. Liquid lead alloy finally returns to the inside of drum 313 through return pipe 328 and branch pipe 319. After completing one heat exchange cycle, the calcium carbide liquid exchanges heat with the liquid lead alloy in the drum 313 in the heat exchange tank 1 via the scraping mechanism 4 and the heat insulation cylinder 411 in the scraping part 41. The temperature decreases and the liquid gradually solidifies. The solidified calcium carbide liquid adheres to the outer surface of the drum 313, forming a solid layer. When there is solidified calcium carbide liquid on the surface of the drum 313, the heat insulation cylinder 411 is activated. The piston rod of the heat insulation cylinder 411 extends, driving the auxiliary plate 412 and the annular scraper 413. The annular scraper 413 moves towards the surface of the drum 313, and the sharp edge of the scraper scrapes off the solidified calcium carbide liquid from the surface of the drum 313. The scraped solidified calcium carbide liquid falls off in the form of particles and falls into the collection hopper below and into the conveying pipe 421. The motor 423 is started, and the motor 423 drives the spiral blade 424 to rotate. The spiral blade 424 rotates in the conveying pipe 421, generating axial thrust, which conveys the solidified calcium carbide liquid particles in the collection hopper forward.
