Therefore, a comprehensive high-value utilization device for waste heat from dry quenching of semi-coke is needed to solve the above problems. Utility Model Content

[0027] In this embodiment, the red-hot coke in the pre-storage chamber 1 enters the dry quenching furnace 2. At this time, the circulating fan 405 pressurizes the inert gas and introduces it into the tubular feedwater preheating device 406 to cool the inert gas. Finally, it is delivered to the discharge mechanism 3 to further cool the red-hot coke. After convective heat exchange, it is discharged through the heat storage component 404. At this point, the inert gas temperature is 900-980 degrees Celsius. The dry quenching furnace 2 is connected to the waste heat boiler 402 through the external pipe 4041. When the gas enters the internal pipe 4044, the inert gas... Body heat radiation heats the water in the circulation pipe 4043. The circulation pipe 4043 is connected to the waste heat boiler 402 to provide additional heat energy. An insulation layer 4042 is installed on the outside of the circulation pipe 4043 to prevent heat dissipation. The inert gas is discharged into the waste heat boiler 402 after being dedusted by the first dust collector 401 for heat exchange.

[0028] Example 2

[0029] like Figures 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the discharge mechanism 3 includes a storage cylinder 301, which is fixedly installed at the bottom end of the dry quenching furnace 2. A baffle 314 is fixedly connected inside the storage cylinder 301. A fixed base 302 is fixedly connected to the bottom end of the storage cylinder 301. A support platform 303 is fixedly connected to the surface of the fixed base 302. A motor 304 is fixedly connected to the surface of the support platform 303. A first synchronous pulley 305 is fixedly connected to the output end of the motor 304. A synchronous belt 306 is movably connected to the surface of the first synchronous pulley 305. The lower end of the fixed base 302 is provided with a sliding groove 313. A sliding ring 312 is movably connected to the surface of the sliding groove 313. A second synchronous pulley 307 is fixedly connected to the surface of the sliding ring 312. The second synchronous pulley 307 is movably connected to the surface of the synchronous belt 306. A turntable 308 is fixedly connected to the surface of the second synchronous pulley 307. A second connecting hole 311 is provided on the surface of the turntable 308.

When the red coke falls, a baffle 314 disperses the red coke so that it is evenly spread in the storage cylinder 301. The red coke is heat-exchanged by the waste heat utilization mechanism 4. After the heat exchange is completed, the motor 304 drives the first synchronous pulley 305 to rotate, which causes the synchronous belt 306 to drive the second synchronous pulley 307 to rotate. The sliding ring 312 rotates in the sliding groove 313. The second connecting hole 311 on the surface of the turntable 308 is aligned with the first connecting hole 310 on the surface of the fixed plate 309, so that the cooled red coke is discharged from the discharge trough formed by the second connecting hole 311 and the first connecting hole 310, which improves the adaptability of the device.

[0031] The working principle of this device for the comprehensive high-value utilization of waste heat from dry quenching of semi-coke will be explained in detail below.

[0032] like Figures 1-5As shown, the inert gas enters the dry quenching furnace 2 through the pre-storage chamber 1. At this time, the circulating fan 405 pressurizes the inert gas and introduces it into the tubular feedwater preheating device 406 to cool it down. Finally, it is delivered to the discharge mechanism 3 to further cool the inert gas. After convective heat exchange, it is discharged through the heat storage component 404. At this point, the inert gas temperature is 900-980 degrees Celsius. The dry quenching furnace 2 is connected to the waste heat boiler 402 through the external pipe 4041. When the gas enters the internal pipe 4044, the inert gas heat radiation heats the water in the circulating pipe 4043. The circulating pipe 4043 is connected to the waste heat boiler 402, providing additional heat energy. A heat insulation layer 4042 is installed on the outside of the circulating pipe 4043 to prevent heat dissipation. The inert gas, after being dedusted by the first dust collector 401, is discharged into the waste heat boiler 402 for heat exchange. The gas after heat exchange is then discharged from the waste heat boiler. 402 is discharged into the second dust collector 403 for secondary dust removal, and finally conveyed to the circulating fan 405 for recycling. The storage cylinder 301 is connected to the fixed base 302, and the support platform 303 on the surface of the fixed base 302 supports the motor 304. When the red coke falls, the baffle 314 disperses the red coke so that it is evenly spread in the storage cylinder 301. The red coke is heat-exchanged by the waste heat utilization mechanism 4. After the heat exchange is completed, the motor 304 drives the first synchronous pulley 305 to rotate, so that the synchronous belt 306 drives the second synchronous pulley 307 to rotate. The sliding ring 312 rotates in the sliding groove 313. The second connecting hole 311 on the surface of the turntable 308 is aligned with the first connecting hole 310 on the surface of the fixed plate 309, so that the cooled red coke is discharged from the discharge trough formed by the second connecting hole 311 and the first connecting hole 310, which improves the adaptability of the device.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
