Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery facilities for steelmaking converters in iron and steel enterprises, specifically to a waste heat recovery device for inertial separation of primary flue gas heat recovery in converters. Background Technology

[0002] During converter smelting, the primary flue gas temperature at the outlet of the vaporization flue in a conventional converter design is 900℃~1000℃. It then enters a wet or dry dust removal system, typically using water spray cooling to lower the temperature to around 200℃ before purification and recovery. Therefore, the waste heat from 900℃ to 200℃ is considered wasted. The main reason this waste heat is not recovered is the risk of explosion in the low-to-medium temperature range of converter gas.

[0003] According to the thermodynamics of combustible gases, a gas explosion requires the simultaneous fulfillment of the following three conditions:

[0004] 1) The mixing ratio of carbon monoxide with oxygen or air is within the explosive limits;

[0005] 2) Carbon monoxide is premixed with oxygen or air below its auto-ignition point (605℃~650℃);

[0006] 3) The system ignition energy is greater than the minimum ignition energy of the converter gas.

[0007] To ensure the safe recovery and utilization of this heat, it is necessary to ensure that the above three conditions cannot be met simultaneously. Therefore, a device is designed to recover the waste heat of the primary flue gas of the converter above 200°C. Utility Model Content

[0048] The converter primary flue gas thermal energy inertial separation waste heat recovery device provided in this embodiment separates high-energy thermal energy through thermal energy inertial separation device 4 and reduces the dust concentration in flue gas through inertial dust collector 8, thereby achieving a fully dry waste heat recovery system with high safety and high stability.

[0049] The following details the design principle of the converter primary flue gas thermal energy inertial separation waste heat recovery device:

[0050] 1) During converter smelting, the flue gas temperature at the outlet of the vaporization cooling flue 1 is 900℃~1000℃, and it enters the high-temperature section radiant waste heat boiler 3 for waste heat recovery. The vaporization cooling flue 1 and the high-temperature section radiant waste heat boiler 3 are connected through the first compensator 21 to absorb the thermal displacement of the equipment. The outlet flue gas temperature of the high-temperature section radiant waste heat boiler 3 is 660℃~700℃, and it enters the thermal inertial separation device 4 for thermal inertial separation.

[0051] 2) The overall shape of the thermal energy inertial separation device 4 is an inverted trapezoid, which increases the bottom outlet area (conventional separation devices are inverted triangles with relatively small outlets), which not only improves separation efficiency but also reduces wear on the lower part. The embedded water-cooled conveying device 45 can safely and promptly transport and discharge high-energy thermal energy, preventing the separated thermal energy from returning to the flue gas and preventing thermal energy accumulation that could cause gas combustion and explosion.

[0052] 3) The thermal energy inertial separation device 4 adopts a water-cooled jacket structure, which can not only improve the service life of the separation device, but also cool the high-energy thermal energy, so that the high-energy thermal energy is cooled while being separated, avoiding the combustion and explosion of converter gas caused by high-energy ignition energy, and further improving the safety of the system.

[0053] 4) The inlet and outlet of the inertial separation device 4 are equipped with a thermal energy analysis device 12. The thermal energy analysis device 12 can calculate the ignition energy of the flue gas by real-time detection of flue gas temperature, flue gas composition, dust concentration and dust particle size. When the ignition energy at the outlet of the inertial separation device 4 is greater than the minimum ignition energy of the converter gas in the subsequent equipment (which may easily cause combustion and explosion in the subsequent equipment), the first drive device 43 is increased to increase the rotation speed of the rotating drum 42, thereby improving the separation efficiency of the inertial separation device 4 and ensuring that the ignition energy at the outlet of the inertial separation device 4 is less than the minimum ignition energy of the converter gas in the subsequent equipment, thus ensuring the safety of the system.

[0054] 5) High-energy pyrotechnic particles are cooled by the embedded water-cooled conveying device 45 and the double-layer flap valve 14, and then stored in the ash collection bin 16 and periodically discharged. The function of the double-layer flap valve 14 is to ensure that the converter gas inside the pyrotechnic inertial separation device 4 does not enter the rapid ash cooler 15, and to ensure that the gas does not leak.

[0055] 6) The flue gas that has undergone inertial separation of thermal energy through the thermal energy separation device 4 enters the medium-temperature radiant convection waste heat boiler 6 through the water-cooled flue duct 5 for safe waste heat recovery, and the outlet flue gas temperature is 560℃~600℃.

[0056] The medium-temperature radiant convection waste heat boiler 6 is equipped with an explosion relief valve 11, which further ensures the safety of the equipment.

[0057] The medium-temperature radiant convection waste heat boiler 6 adopts a large radiant chamber and a wide-channel convection screen structure, which not only ensures the efficiency of waste heat recovery, but also reduces the ash accumulation on the boiler wall.

[0058] 7) The flue gas from the outlet of the medium-temperature radiant-convective waste heat boiler 6 enters the inertial dust collector 8 through the cyclone separator 7. The inertial dust collector 8 is equipped with cyclones 7 at both its inlet and outlet. The rotational speed of the cyclone separator 72 can be increased by the second drive device 73, thereby improving the dust removal efficiency of the inertial dust collector 8, reducing the dust concentration in the flue gas, reducing ash accumulation on the walls of the low-temperature convective waste heat boiler 9, and improving operational stability.

[0059] 8) The inertial dust collector 8 is equipped with a dust concentration analyzer 13, which can measure the dust concentration of the flue gas in real time. Based on the dust concentration, the rotation speed of the cyclone drum 72 is controlled by an interlock to reduce the dust concentration of the flue gas entering the low-temperature section of the convective waste heat boiler 9.

[0060] 9) The ash at the bottom of the inertial dust collector 8 enters the rapid ash cooler 15 through the double-layer flap valve 14 for cooling, and then enters the ash collection bin 16 for storage and periodic discharge. The function of the double-layer flap valve 14 is to ensure that the converter gas inside the inertial dust collector 8 does not enter the rapid ash cooler 15, and to ensure that the gas does not leak.

[0061] 10) Flue gas with low dust concentration enters the low-temperature section convective waste heat boiler 9 for waste heat recovery. The outlet flue gas temperature of the low-temperature section convective waste heat boiler 9 is ~200℃. It is transported to the downstream device for gas purification and recovery through the low-temperature gas pipeline 10. The low-temperature section convective waste heat boiler 9 is equipped with an explosion relief valve 11 to further ensure the safety of the equipment.

[0062] During converter smelting, the flue gas temperature at the outlet of the vaporization cooling flue is 900℃~1000℃. It enters the high-temperature section radiant waste heat boiler for waste heat recovery. The outlet flue gas temperature of the high-temperature section radiant waste heat boiler is 660℃~700℃. High-energy thermal energy is separated in the thermal energy inertial separation device. Thermal energy analysis devices are installed at the inlet and outlet of the thermal energy inertial separation device. The rotation speed of the rotating drum is adjusted according to the thermal energy at the inlet and outlet, thereby improving the separation efficiency of the thermal energy inertial separation device. This ensures that the ignition energy in the flue gas after passing through the thermal energy inertial separation device is less than the minimum ignition energy of the converter gas, thus preventing high-energy thermal energy from entering subsequent equipment and causing converter gas combustion and explosion.

[0063] After inertial separation of thermal energy, the high-temperature flue gas enters the medium-temperature section radiative-convective waste heat boiler for waste heat recovery. Its outlet flue gas temperature is 560℃~600℃. Then, the flue gas enters the inertial dust collector for further dust removal. After that, the flue gas enters the low-temperature section convective waste heat boiler for waste heat recovery. The outlet flue gas temperature of the convective waste heat boiler is ~200℃. It is then transported to subsequent equipment for gas purification and recovery through gas pipelines.

[0064] This invention fully recovers the waste heat above 200℃ from the primary flue gas of the converter, achieving fully dry waste heat recovery and purification. It also avoids the risk of flash explosion of converter gas within the 605-650℃ range, significantly improving system safety. The medium-temperature radiant-convective waste heat boiler adopts a large radiant chamber + wide-channel convection screen structure, ensuring efficient waste heat recovery while reducing ash accumulation on the boiler walls, thus improving system stability.

[0065] This embodiment also provides a method for recovering waste heat from the inertial separation of primary flue gas from a converter, including the following steps:

[0066] (1) Flue gas with a temperature of 900℃~1000℃ enters the high-temperature section radiant waste heat boiler from the vaporization cooling flue for waste heat recovery. The compensator absorbs the heat displacement. The outlet flue gas temperature of the radiant waste heat boiler is 660℃~700℃. The flue gas enters the thermal inertial separation device for thermal inertial separation.

[0067] (2) The pyrolysis device detects the flue gas temperature, flue gas composition, dust concentration and dust particle size in real time, and calculates the ignition energy of the flue gas. When the ignition energy at the top outlet of the pyrolysis inertial separator is greater than the minimum ignition energy of the converter gas in the subsequent equipment, the first drive device increases the rotation speed of the rotating drum, thereby improving the separation efficiency of the pyrolysis inertial separator and ensuring that the ignition energy at the outlet of the pyrolysis inertial separator is less than the minimum ignition energy of the converter gas in the subsequent equipment.

[0068] (3) The flue gas that has completed the inertial separation of thermal energy through the thermal energy separation device enters the medium-temperature section radiant convection waste heat boiler through the water-cooled flue 5 for waste heat safe recovery. The outlet flue gas temperature of the medium-temperature section radiant convection waste heat boiler is 560℃~600℃.

[0069] (4) The flue gas from the outlet of the medium-temperature radiant convection waste heat boiler enters the inertial dust collector 8 through the cyclone separator. The dust concentration analyzer measures the dust concentration of the flue gas in real time. Based on the dust concentration, the rotation speed of the cyclone separator 7 is controlled to reduce the dust concentration of the flue gas entering the low-temperature convective waste heat boiler.

[0070] (5) The flue gas enters the low-temperature section convective waste heat boiler for waste heat recovery, and then is transported to the subsequent equipment for gas purification and recovery through the low-temperature gas pipeline.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various modifications or alterations to the present invention, such as adjusting the form of the water-cooled flue 5 to adopt a steam-cooled or insulated flue duct, adjusting the cooling method of the thermal energy inertial separation device 4 to adopt a steam-cooled or insulated method, adjusting the inlet and outlet flue gas temperatures of the high-temperature radiant waste heat boiler 3, adjusting the inlet and outlet flue gas temperatures of the medium-temperature radiant waste heat boiler 6, and adjusting the inlet and outlet flue gas temperatures of the low-temperature radiant waste heat boiler 9.
