Description

Technical Field

[0001] The invention relates to the technical field of boiler equipment, in particular to a converter vaporization energy-saving waste heat boiler. Background Art

[0002] A waste heat boiler, as the name implies, is a boiler that utilizes the waste heat in waste gas, waste materials or waste liquid in various industrial processes and the heat generated by the combustion of combustible substances to heat water to a certain temperature. The converter waste heat boiler is located in the charging and dust removal span of the converter workshop. The temperature of the flue gas escaping from the converter furnace mouth is about 1600℃, and the outlet temperature of the converter vaporization cooling device is required to be about 850℃. The purpose is to collect the high-temperature flue gas in the converter smelting process and cool it down, recovering a large amount of heat energy for production and life use, and it has been widely used.

[0003] After searching, the Chinese patent number CN221141764U discloses a device for recovering waste heat of steel slag using the converter vaporization system, which involves the technical field of waste heat recovery in steelmaking production. The patent includes a hot stuffy pool and a cover plate, the cover plate is covered on the hot stuffy pool, a group of spray heads are penetrated on the cover plate, a steam pipe is provided on the cover plate, the steam pipe passes through the cover plate and is connected to a dust collector, the dust collector is connected to a heat accumulator, the heat accumulator is connected to the converter vaporization system, the steam output port of the heat accumulator is connected to an external network steam pipe, and the external network steam pipe is connected to the heating terminal. In the process of hot stuffy treatment of steel slag, the energy recovery rate is improved and the construction cost is reduced.

[0004] The above patent generates steam by spraying water into the hot and stuffy pool through a spray head, and recovers the steam to the heat accumulator through a steam pipe, so that the waste heat can be utilized. However, in actual use, the spray head needs to work first. After the steam is generated, it is transmitted to the dust collector and the heat accumulator through the steam pipe. In the process of the steam moving through the steam pipe, the heat will be dissipated at the wall of the steam pipe, thereby affecting the subsequent dust removal and heat storage effects. Based on this, the present invention designs a converter vaporization energy-saving waste heat boiler to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a converter vaporization energy-saving waste heat boiler, which solves the problem of easy heat loss in the background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A converter gasification energy-saving waste heat boiler, comprising:

[0008] A working furnace, wherein a connector is installed on the top of the working furnace, a connecting valve is installed in the middle of the connector, and a connecting pipe is also installed on the top of the working furnace;

[0009] A heat conduction mechanism, which is located at the outer ring of the connecting pipe and is used for utilizing the waste heat. The heat conduction mechanism includes a working component, a linkage component and a pneumatic component. The working component is located at the outer ring of the connecting pipe and is used for utilizing the waste heat. The linkage component is located at the bottom of the working component and is used for the rotation of the pneumatic component. The pneumatic component is located at the bottom of the linkage component and is used for accelerating the movement of the flue gas in the working furnace.

[0010] The working assembly includes a transfer box installed on the top of the working furnace, a smoke pipe is installed at the bottom of the transfer box, and the smoke pipe is a plurality of groups of spirally wound around the outer ring of the connecting pipe. The bottom of the smoke pipe passes through the side wall of the working furnace and extends into the inner cavity of the working furnace.

[0011] Preferably, the connecting assembly includes a top pipe installed on the top of the connecting pipe, and a heat transfer assembly is also installed on the outer ring of the connecting pipe and the flue gas pipe.

[0012] Preferably, the heat transfer assembly includes a heat transfer tube installed on the outer ring of the connecting tube, a water inlet is installed on the top of the back of the heat transfer tube, a water outlet is installed on one side of the bottom of the heat transfer tube, and a connecting assembly is also installed in the inner cavity of the connecting tube.

[0013] Preferably, the connection assembly includes a regulating valve installed in the inner cavity of the connecting pipe, a top pipe is also installed on the top of the connecting pipe, and an output pipe is installed on one side of the top pipe.

[0014] The high-temperature flue gas generated by the working furnace during the smelting process is first collected. When the connecting valve is closed, the high-temperature flue gas enters the heat transfer mechanism through the flue pipe. The flue pipe is designed as multiple groups of spirals wrapped around the outer ring of the connecting pipe. This structure effectively increases the contact area between the flue gas and the heat transfer pipe and prolongs the heat exchange time. The heat transfer pipe is installed close to the outer ring of the connecting pipe to form a heat exchange interface. Cooling water enters the heat transfer pipe through the water inlet, absorbs the heat released by the flue gas when flowing in the pipe, and is converted into high-temperature steam or hot water, which is then discharged through the outlet pipe for subsequent use.

[0015] Preferably, the linkage assembly includes a connecting seat installed in the inner cavity of the water outlet pipe, a driving shaft is rotatably connected in the inner cavity of the connecting seat, an outer wall of the driving shaft is fixedly connected to a driving fan blade, and an outer ring of the driving shaft is installed with a driving bevel gear.

[0016] Preferably, the linkage assembly also includes a protective tube, a linkage shaft is installed in the inner cavity of the protective tube, linkage bevel gears are installed on the top and bottom of the linkage shaft, the linkage bevel gear at the top is meshed with the active bevel gear, and a drive seat is installed at the bottom of the protective tube.

[0017] When water flows through the outlet pipe, the water flow power is used to drive the active blades installed in the outlet pipe to rotate. The active blades are connected to the active shaft, which in turn drives the active bevel gear to rotate. The active bevel gear meshes with the top linkage bevel gear in the linkage assembly, and drives the linkage shaft to rotate through gear transmission. Linkage bevel gears are installed at the upper and lower ends of the linkage shaft, and the bottom linkage bevel gear meshes with the driven bevel gear to realize the rotation of the driven bevel gear. The driven bevel gear is connected to the worm, and the rotation of the worm is kept stable by the fixed seat without offset.

[0018] Preferably, a worm is rotatably connected to the inner cavity of the driving seat, a driven bevel gear is installed on one side of the worm, the driven bevel gear is meshed with the linkage bevel gear located at the bottom, and a fixed seat is also installed in the inner cavity of the driving seat and is used to limit the rotation of the worm.

[0020] The pneumatic assembly includes a protective cover installed at the bottom of the working furnace, a driven fan and a turbine. The turbine and the worm are meshed with each other. When the worm rotates, the turbine rotates accordingly, which in turn drives the driven fan to rotate. The rotation of the driven fan accelerates the flow of flue gas in the inner cavity of the working furnace, improves the heat exchange efficiency between the flue gas and the heat transfer tube, and promotes the rapid discharge of flue gas, reducing heat loss. There are filter holes in the protective cover to prevent impurities from entering the pneumatic system and ensure the stable operation of the system.

[0021] Preferably, the transfer box and the connecting pipe are fixedly connected by limiting bolts, and the transfer box and the top pipe are fixedly connected by fixing bolts, and the limiting bolts and the fixing bolts are distributed in multiple groups of circular arrays.

[0022] The converter gasification energy-saving waste heat boiler of the present invention realizes efficient recovery and utilization of waste heat through the heat exchange of high-temperature flue gas, the linkage mechanism driven by water power and the design of accelerated flue gas discharge, while optimizing the flue gas flow path and improving the overall energy utilization efficiency. This design not only reduces heat loss, but also improves the environmental protection performance and economic benefits of the system.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0024] 1. The present invention adopts multiple groups of spirally wound flue gas pipe structures, which effectively increases the contact area and heat exchange time between high-temperature flue gas and heat transfer pipes, so that the heat in the flue gas can be more fully absorbed by cooling water and converted into high-temperature steam or hot water, thereby significantly improving the waste heat recovery efficiency; the heat transfer pipe is installed close to the outer ring of the connecting pipe to form an efficient heat exchange interface, which reduces the loss of heat during the transmission process and further improves the efficiency of waste heat recovery.

[0025] 2. The present invention, by designing a pneumatic component, utilizes the mutual engagement of the worm and the turbine to drive the driven fan to rotate, thereby accelerating the flow of flue gas in the inner cavity of the working furnace, which not only improves the heat exchange efficiency between the flue gas and the heat transfer tube, but also promotes the rapid discharge of flue gas and reduces the heat loss caused by flue gas retention; the structural design of the spiral flue gas pipe enables the flue gas to form a spiral upward trajectory during the flow process, thereby extending the residence time of the flue gas in the working furnace and increasing the adequacy of the heat exchange.

[0026] 3. The present invention innovatively utilizes the power of water flowing through the outlet pipe to drive the active fan blades to rotate, and drives the worm and turbine to rotate through the gear transmission system, thereby realizing the automatic operation of the pneumatic component. This water-powered linkage mechanism does not require external energy input, achieving the purpose of energy conservation and emission reduction. This design simplifies the system structure, reduces operating costs, and improves the reliability and stability of the system. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The working principle of the embodiment of the present invention is as follows: the driven fan 404 and the turbine 405 are mounted on the fixed rod 403, and the turbine 405 is meshed with the worm 309. When the worm 309 rotates, the meshed turbine 405 and the driven fan 404 are driven to rotate, accelerating the flow of flue gas in the inner cavity of the working furnace 101. This acceleration effect not only improves the heat exchange efficiency between the flue gas and the heat transfer pipe 501, but also promotes the rapid discharge of the flue gas and reduces heat loss. The protective cover 401 is mounted at the bottom of the working furnace 101, and a filter hole 402 is provided inside to prevent impurities from entering the pneumatic system.

[0053] Working principle: The working furnace 101 generates high-temperature flue gas during the smelting process. At this time, the connecting valve 103 is closed, and the bottom of the flue pipe 202 penetrates the side wall of the working furnace 101, and the high-temperature flue gas enters the inner cavity of the flue pipe 202. The heat transfer pipe 501 is installed close to the outer ring of the connecting pipe 104 to form a heat exchange interface. The water inlet 502 introduces cooling water. When the cooling water flows in the heat transfer pipe 501, it absorbs the heat released by the flue gas and converts it into high-temperature steam or hot water, which is discharged through the water outlet 503 for subsequent use. Multiple groups of spirally surrounded flue pipes 202 are arranged around the connecting pipe 104. This spiral structure effectively increases the contact area between the flue gas and the heat transfer pipe 501 and prolongs the heat exchange time. The flue gas passes through the flue pipe 202 and enters the inner cavity of the transfer box 201. The setting of the control valve 203 and the transfer pipe 204 facilitates the adjustment of the flow direction and flow of the flue gas to meet different working requirements.

[0054] When water flows through the outlet pipe 503, the active blade 303 fixed on the active shaft 302 rotates with the water flow, driving the active shaft 302 and the active bevel gear 304 to rotate. The active bevel gear 304 is meshed with the top linkage bevel gear 307, driving the linkage shaft 306 to rotate, and then driving the bottom linkage bevel gear 307 to rotate. The driven bevel gear 310 is meshed with the bottom linkage bevel gear 307 to realize the rotation of the worm 309. The fixed seat 312 ensures that the worm 309 rotates stably without deviation.

[0055] The driven fan 404 and the turbine 405 are mounted on the fixed rod 403, and the turbine 405 is meshed with the worm 309. When the worm 309 rotates, the meshed turbine 405 and the driven fan 404 are driven to rotate, accelerating the flow of the flue gas in the inner cavity of the working furnace 101. This acceleration effect not only improves the heat exchange efficiency between the flue gas and the heat transfer tube 501, but also promotes the rapid discharge of the flue gas and reduces heat loss. The protective cover 401 is mounted at the bottom of the working furnace 101, and a filter hole 402 is provided inside to prevent impurities from entering the pneumatic system.

[0056] When waste heat utilization is not needed, the connector 102 and the connecting valve 103 can be opened, and the smoke enters the inner cavity of the connecting pipe 104. The connecting pipe 104, as the main channel for smoke transmission, can quickly discharge the smoke and discharge it from the output pipe 603 on the side of the top pipe 602, achieving the purpose of rapid discharge and treatment.

[0057] The converter gasification energy-saving waste heat boiler of the present invention allows the high-temperature flue gas generated by the working furnace 101 to flow in the flue gas pipe 202 and exchange heat with the cooling water in the heat transfer pipe 501. At the same time, the linkage component 3 uses the water flow power to drive the worm 309 to rotate, thereby driving the driven fan 404 and the turbine 405 in the pneumatic component 4 to rotate and accelerate the flow of flue gas. This series of processes realizes the efficient recovery and utilization of waste heat, optimizes the flue gas flow path, and improves the overall energy utilization efficiency.
