Description

Technical Field

[0001] The invention relates to the technical field of reduction furnace waste heat utilization devices, and in particular to a copper smelting slag reduction furnace waste heat utilization device. Background Art

[0002] Hydrogen reduction furnace is an important heat treatment equipment, widely used in metallurgy, chemical industry, building materials and electronic industry. Hydrogen reduction furnace refers to a device that reduces metals, ceramics and other materials by heating hydrogen. Its principle is to use the strong reducing property of hydrogen at high temperature to reduce metal ions or other ions to pure metals or alloys. Specifically, under high temperature conditions, hydrogen reacts with metal oxides or other compounds to generate the required metal or compound and water vapor.

[0003] However, when utilizing the waste heat from the reduction furnace, high-temperature water vapor will carry a trace amount of hydrogen into the waste heat utilization system. When utilizing the waste heat, water vapor and hydrogen will pass through a large number of pipes or heat exchange spaces. Although the hydrogen content carried in the water vapor is relatively low, at about 1%-3%, and the lower explosion limit of hydrogen in the air is 4% (volume concentration), there are still significant safety risks in the utilization of hydrogen in waste heat, especially in high temperature environments, which will reduce the actual lower explosion limit of hydrogen. Although the hydrogen concentration of 1%-3% does not reach the explosion range at room temperature, it still has the possibility of explosion under high temperature conditions, especially when there is leakage in the system or local hydrogen enrichment (such as dead corners in the pipeline), it will trigger the possibility of hydrogen explosion.

[0004] In view of this, we propose a waste heat utilization device for copper smelting slag reduction furnace. Summary of the invention

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See also Figure 1-Figure 13 A device for utilizing waste heat from a copper smelting slag reduction furnace comprises a reduction furnace 1 for reducing copper with hydrogen. The reduction furnace 1 is provided with an anti-leakage mechanism 2 for preventing hydrogen from escaping. The anti-leakage mechanism 2 comprises a waste heat tank 21. The waste heat tank 21 is a double-layer structure, which is convenient for uniformly heating the waste heat tank 21, and the heated gas does not contact the inside of the waste heat tank 21. The waste heat tank 21 is fixedly connected to the reduction furnace 1. An air inlet pipe 22 is fixedly installed on one side of the waste heat tank 21, and an air outlet pipe 23 is fixedly installed on the other side of the waste heat tank 21. Nitrogen is filled through the air inlet pipe 22 to form a nitrogen barrier for preventing hydrogen from escaping. The air outlet pipe 23 is used for the recycling of nitrogen.

[0043] See also Figure 1-Figure 2 A feed port 3 is fixedly installed at the top of the waste heat tank 21 for feeding copper.

[0044] See also Figure 4-Figure 13 The reduction furnace 1 is provided with a waste heat mechanism 4 for utilizing the waste heat generated by reducing copper with hydrogen. When utilizing the waste heat, the hydrogen and water vapor are separated to avoid potential safety hazards when utilizing the waste heat of hydrogen.

[0045] See also Figure 4-Figure 6 The waste heat mechanism 4 includes a waste heat pipe 41, which is fixedly connected to the reduction furnace 1 and is used to discharge the waste gas generated by hydrogen reduction of copper, and the waste gas includes water vapor and a small amount of hydrogen. The waste gas will carry a large amount of heat when it is discharged. The other end of the waste heat pipe 41 is fixedly connected to the supercharger housing 42, and an impeller 43 is fixedly installed at the center position inside the supercharger housing 42, and the impeller 43 is driven by a motor. The impeller 43 is driven to rotate by the motor, and the high-speed rotating impeller 43 performs work on the waste gas, thereby driving the waste gas to move and causing the waste gas to rotate.

[0046] A plurality of diffuser blades 44 are fixedly installed in the supercharger housing 42, and the plurality of diffuser blades 44 are distributed in a circular array. A diffuser channel 441 is provided between adjacent diffuser blades 44. The diffuser channel 441 is a structure with a large opening at one end and a small opening at the other end, and the small opening portion is close to the impeller 43. The narrowest portion between adjacent diffuser blades 44 is a throat 442. An annular channel 45 is provided between the inside of the supercharger housing 42 and the diffuser blades 44, and an exhaust port 46 is fixedly installed on the supercharger housing 42, and the annular channel 45 and the exhaust port 46 are communicated.

[0047] The exhaust gas enters the impeller 43 through the waste heat pipe 41 and is driven by the high-speed rotating impeller 43. The kinetic energy is then converted into pressure through the diffuser channel 441 between the diffuser blades 44. Finally, the pressurized exhaust gas enters the exhaust port 46 through the annular channel 45 and is discharged.

[0048] See also Figure 3 and Figure 7 The exhaust port 46 is fixedly connected to a flow equalizing tube 47, and a plurality of flow equalizing plates 471 are fixedly installed in the flow equalizing tube 47. The flow equalizing plates 471 are provided with a plurality of flow equalizing holes 472, and the plurality of flow equalizing holes 472 are distributed in an array. The pressurized exhaust gas passes through the plurality of flow equalizing plates 471 and the flow equalizing holes 472, so that the pressurized exhaust gas is evenly flowed, which stabilizes the gas flow and avoids the occurrence of local concentration gradients of water vapor and hydrogen in the exhaust gas.

[0049] See also Figure 8-Figure 9A pressure regulating mechanism 48 is provided between the supercharger housing 42 and the equalizing pipe 47, which is used for balancing the pressure during the exhaust gas supercharging, and can passively respond to the pressure after the exhaust gas supercharging, so that the pressure can be quickly and automatically adjusted to prevent the pressure of the exhaust gas supercharging from deviating from the optimal separation range. The pressure regulating mechanism 48 includes a slider 481, which is slidably installed at the position of the throat 442, and the slider 481 is adapted to the shape of the throat 442. The cross-sectional area of ​​the throat 442 can be adjusted by the displacement of the slider 481. Since the cross-sectional area of ​​the throat 442 determines the maximum flow rate, the airflow velocity and pressure conversion efficiency can be controlled by adjusting the cross-sectional area of ​​the throat 442.

[0050] An adjusting ring 485 is fixedly mounted on one end of the slider 481, a sliding frame 483 is fixedly mounted on the supercharger housing 42, the adjusting ring 485 and the inside of the sliding frame 483 are slidably connected, an inflatable ring 484 is fixedly mounted on the sliding frame 483, a plurality of metal bellows 486 are fixedly connected between the inflatable ring 484 and the adjusting ring 485, the plurality of metal bellows 486 are arranged in an array, and the metal bellows 486 are connected to the inflatable ring 484. The inflatable ring 484 is connected to the flow equalizing tube 47 through a buffer tube 482. A plurality of springs 487 are also fixedly connected between the inflatable ring 484 and the adjusting ring 485, and the plurality of springs 487 are arranged in an array.

[0051] The pressurized and equalized exhaust gas enters the inflation ring 484 through the buffer tube 482. When the pressure of the exhaust gas does not change or changes slightly, the expansion size of the metal bellows 486 remains basically unchanged, and the metal bellows 486 will not expand or contract. With the preload force of the spring 487, the exhaust gas remains stable after being pressurized. When the pressure of the supercharged and equalized exhaust gas changes, the expansion length of the metal bellows 486 will change. The metal bellows 486 drives the adjustment ring 485 to slide along the inside of the sliding frame 483. The displacement of the adjustment ring 485 drives the slider 481 to move, thereby adjusting the cross-sectional size of the throat 442, thereby adjusting the maximum airflow passing through the throat 442, and then controlling the airflow velocity and pressure conversion efficiency, and finally achieving the effect of stabilizing the pressure of the supercharging.

[0052] Specifically, when the pressure of the exhaust gas after supercharging and equalizing suddenly increases, the telescopic length of the metal bellows 486 will be further extended. The extension of the length of the metal bellows 486 drives the adjustment ring 485 to slide along the inside of the sliding frame 483. The sliding of the adjustment ring 485 drives the slider 481 to move toward the supercharger housing 42. The displacement of the slider 481 causes the cross-sectional area of ​​the throat 442 to decrease. The reduction in the cross-sectional area of ​​the throat 442 causes the gas flow rate to decrease and the flow rate to increase, thereby increasing the kinetic energy of the exhaust gas and reducing the pressure of the exhaust gas conversion. At the same time, when the pressure of the exhaust gas after supercharging and equalizing suddenly decreases, the metal bellows 486 contracts, causing the cross-sectional area of ​​the throat 442 to increase, which plays a role in increasing the pressure of the exhaust gas. Thereby, the pressure of the supercharging of the exhaust gas can be dynamically adjusted, so that the pressure is always maintained within a certain range, and the entire adjustment process is passive adjustment, without manual operation and power supply, and is more stable.

[0053] See also Figure 10-13 One end of the flow balancing tube 47 is fixedly connected with a vortex tube 49, which is used to separate water vapor and hydrogen in the exhaust gas. When the exhaust gas enters the vortex tube 49, a spiral vortex will be formed. Since the density of hydrogen is much lower than that of water vapor, the centrifugal force will cause stratification in the high-speed vortex. The water vapor is thrown to the periphery and finally discharged from the hot end outlet 494. The hydrogen gathers in the center of the vortex tube 49 to form a low-temperature and low-pressure core flow, which is discharged from the cold end outlet 495. Thus, the separation effect is achieved.

[0054] The vortex tube 49 includes an air inlet 491, one end of the air inlet 491 is fixedly connected to the flow equalizing tube 47, and a plurality of vortex blades 4911 are fixedly installed in the air inlet 491. The plurality of vortex blades 4911 are distributed in an array, and the vortex blades 4911 are airfoil structures, and the end close to the flow equalizing tube 47 is arc-shaped, and the thickness of the vortex blades 4911 gradually decreases from the end close to the flow equalizing tube 47 to the end away from the flow equalizing tube 47, and the surface of the vortex blades 4911 is a smooth structure.

[0055] The vortex blade 4911 is used to guide the tangential movement of the gas, force the airflow to rotate, and force pre-swirl before the gas enters the vortex tube 49 to ensure the initial swirl intensity. At the same time, the arc-shaped structure is used to reduce local overheating caused by the impact of high-temperature airflow. The thickness of the vortex blade 4911 gradually decreases to inhibit vortex shedding, and the smooth surface avoids flow stratification in the airflow.

[0056] The air inlet 491 is fixedly mounted on the pipe 492, and a hot end outlet 494 and a cold end outlet 495 are respectively opened at both ends of the pipe 492. A vortex generator 493 is fixedly mounted on the pipe 492 at a symmetrical position of the air inlet 491, so that the exhaust gas entering the pipe 492 after supercharging and pre-spinning generates a spiral swirl, and the exhaust gas after supercharging and pre-spinning moves in a spiral swirl through the inside of the pipe 492. Since the density of hydrogen is much lower than that of water vapor, stratification will occur under the action of centrifugal force in the high-speed swirl, and the water vapor will be thrown to the periphery, spirally move along the inner wall of the pipe 492, and finally be discharged from the hot end outlet 494. Hydrogen gathers in the center of the vortex tube 49 to form a low-temperature and low-pressure core flow, and is finally discharged from the cold end outlet 495.

[0057] The inner wall of the pipe 492 is provided with multiple groups of flow stabilizing blades 4921, which are evenly distributed in an array. Each group of flow stabilizing blades 4921 has multiple flow stabilizing blades distributed along a circular array, and the flow stabilizing blades 4921 are tilted along the axis of the pipe 492. The flow stabilizing blades 4921 can strengthen the spiral swirl, thereby compensating for the natural attenuation of the swirl intensity caused by the excessive length of the pipe 492. At the same time, the flow stabilizing blades 4921 can also optimize the flow field distribution in the pipe 492, avoid the deviation of the swirl center, and thus improve the uniformity of the separation of hydrogen and water vapor.

[0058] A device for utilizing waste heat from a copper smelting slag reduction furnace, the working principle of which is as follows:

[0059] After the copper slag is reduced by hydrogen in the reduction furnace 1, water vapor will be generated. The water vapor carries a trace amount of hydrogen into the supercharger housing 42 through the waste heat pipe 41, starts the motor, and the motor drives the impeller 43 to rotate. The impeller 43 rotates at high speed to drive the exhaust gas to rotate. The exhaust gas then converts kinetic energy into pressure through the diffuser channel 441 between the diffuser blades 44. Finally, the pressurized exhaust gas enters the exhaust port 46 through the annular channel 45 and is discharged. The pressurized exhaust gas enters the flow equalizing pipe 47 through the exhaust port 46, passes through multiple flow equalizing plates 471 and flow equalizing holes 472, so that the pressurized exhaust gas is evenly distributed, which stabilizes the gas flow and avoids the local concentration gradient of water vapor and hydrogen in the exhaust gas.

[0060] When the exhaust gas after pressurization and equalization finally experiences a large pressure change, the telescopic length of the metal bellows 486 will change. The metal bellows 486 will drive the adjustment ring 485 to slide along the inside of the sliding frame 483. The displacement of the adjustment ring 485 will drive the displacement of the slider 481, thereby adjusting the cross-sectional size of the throat 442, thereby adjusting the maximum air flow rate passing through the throat 442, and then controlling the air flow velocity and pressure conversion efficiency, and finally achieving the effect of stabilizing the control of the boost pressure.

[0061] The stable pressurized and uniformly-flowed exhaust gas enters the interior of the pipe 492 through the air inlet 491, and then passes through the vortex blades 4911 when passing through the air inlet 491. The vortex blades 4911 are used to guide the tangential movement of the gas, force the airflow to rotate, and force pre-swirl before the gas enters the vortex tube 49 to ensure the initial swirl strength. The exhaust gas that has undergone the initial swirl further increases the swirl strength through the vortex generator 493. Since the density of hydrogen is much lower than that of water vapor, stratification will occur under the action of centrifugal force in the high-speed swirl, and the water vapor will be thrown to the periphery, spiraling along the inner wall of the pipe 492, and finally discharged from the hot end outlet 494. Hydrogen gathers in the center of the vortex tube 49 to form a low-temperature and low-pressure core flow, which is finally discharged from the cold end outlet 495.

[0062] And due to the special structure of the vortex tube 49, the temperature of the water vapor at the hot end outlet 494 will be further increased, and the water vapor at the hot end outlet 494 is connected to the hollow structure connected to the waste heat tank 21, so that the waste heat tank 21 can be evenly heated, so that the raw materials and nitrogen in the waste heat tank 21 can be heated, and the subsequent reaction efficiency can be accelerated, saving time and cost. And the heated nitrogen can be used for the treatment of the raw materials to remove the water vapor and air in the raw materials.

[0063] The hydrogen and part of the water vapor discharged from the cold end outlet 495 will experience a certain degree of cooling, but it is still far higher than the condensation temperature of the water vapor and will not cause the water vapor to liquefy. The hydrogen can also be enriched, making it easier to cool the hydrogen and part of the water vapor discharged from the cold end outlet 495, so that the hydrogen can be quickly recycled.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0065] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
