Description

Technical Field

[0001] The invention relates to the technical field of tail gas heat energy utilization devices, and in particular to a hot tank steam tail gas recycling device. Background Art

[0002] High-temperature tail gas and steam are common by-products in industrial production. High-temperature tail gas mainly comes from the combustion process, such as high-temperature flue gas (usually 300°C~1000°C) generated by the combustion of fuels such as boilers, gas turbines, internal combustion engines, and metallurgical furnaces; or chemical reactions, such as the exothermic reaction tail gas of cement kilns and chemical reactors; or industrial emissions, such as process exhaust gas from drying equipment and glass melting furnaces. The main source of steam is high-pressure steam generated by boilers (used for power generation or process steam) and low-pressure steam generated by waste heat in industrial processes (such as distillation and drying). The recycling of heat energy from high-temperature tail gas and steam can significantly improve energy efficiency and reduce carbon emissions. At present, there are two main heat exchange methods. One is direct heat exchange, such as a spray tower: high-temperature tail gas directly contacts water for heat exchange, which is simple but may cause water pollution. One is indirect heat exchange, such as a shell and tube heat exchanger: high-temperature tail gas heats water through the metal tube wall to avoid cross contamination, and a heat pipe heat exchanger: using heat pipes to efficiently conduct heat, suitable for tail gas containing corrosive components.

[0003] After searching, the existing patent (Announcement No.: CN109114992A) discloses a method for recycling waste heat of desulfurized tail gas, which introduces high-temperature pre-desulfurized tail gas into high-temperature heat transfer oil tank 1, and the high-temperature pre-desulfurized tail gas conducts heat with the heat transfer oil in the heat transfer oil pipe 6. Since the high-temperature pre-desulfurized tail gas is outside and the amount is large, and the heat transfer oil is inside the heat transfer oil pipe 6 and the amount is small, the temperature of the heat transfer oil can be quickly increased in the high-temperature heat transfer oil tank 1, and then pumped into the high-temperature oil heat exchange tank 3 through the circulation pump 4. This invention utilizes the waste heat of the pre-desulfurized tail gas and adopts a waste heat utilization system with a special structural design to fully utilize the heat energy of the tail gas, so that it can be vaporized to generate steam to meet production needs.

[0004] The above scheme is similar to the traditional pipeline indirect heat exchange, which introduces the heat flow into the pipeline and exchanges heat with water through the outer wall of the pipeline. However, there are still some shortcomings in the above scheme. First, the heat exchange pipeline and the water are in a relatively static state, which makes the thermal uniformity of the water low. Secondly, the hot air flow in the heat exchange pipeline has a stable flow trend. The formed hot air flow column can only heat the pipe wall well in the part that fits the inner wall of the pipeline, while the heat at the center of the hot air flow column is difficult to be fully utilized, resulting in low heat exchange efficiency, and the heat in the heat flow cannot be effectively utilized, reducing the heat exchange capacity.

[0005] In view of this, the present invention proposes a hot tank steam tail gas recycling device. Summary of the invention

High-temperature steam and tail gas generated by external equipment are accelerated through the Tesla valve pipe and then introduced into the stirring mechanism.

[0020] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of the present invention.

[0021] Embodiment 1 Please refer to Figures 1 - 7 , a hot tank steam tail gas recycling device, including: a water storage tower 1, a Tesla valve pipe 2 is fixedly penetrated through the outer wall of the lower side of the water storage tower 1, and a stirring mechanism 7 is arranged at one end of the Tesla valve pipe 2 located inside the water storage tower 1. High-pressure gas is introduced into the stirring mechanism 7 through the Tesla valve pipe 2, so that the stirring mechanism 7 can be rotated above the Tesla valve pipe 2.

[0022] Among them, a connecting mechanism 8 is arranged inside the water storage tower 1 for installing the stirring mechanism 7, and a supporting assembly 9 for installing the connecting mechanism 8 is arranged between the connecting mechanism 8 and the inner wall of the water storage tower 1.

[0023] Specifically, the stirring mechanism 7 includes a vertical pipe 71 rotatably connected to one end of the Tesla valve pipe 2, an impeller 72 is fixedly sleeved on the outer wall of the vertical pipe 71, the top end of the vertical pipe 71 is fixedly communicated with a rotating cover 73, and air injection pipes 74 communicating with the inside of the rotating cover 73 are annularly and arrayedly distributed on the outer periphery of the rotating cover 73.

[0024] Specifically, the connection mechanism 8 includes a hollow cover 81 rotatably connected to the riser 71. The rotary cover 73 is disposed inside the hollow cover 81, and the rotary cover 73 is rotationally sealed with the bottom of the hollow cover 81.

[0025] Furthermore, the connection mechanism 8 further includes a hollow column 82 disposed above the hollow cover 81. A communication cavity 84 is formed through the top of the hollow cover 81. A hollow cylinder 83 is fixedly connected between the hollow column 82 and the hollow cover 81. A suspension seat 86 is fixedly suspended inside the communication cavity 84 by a plurality of fixing rods 85. The suspension seat 86 is rotatably connected to the rotary cover 73.

[0026] Even further, the supporting assembly 9 includes a ring 91. The ring 91 is fixedly connected to the hollow cover 81 through a U-shaped frame 93. A cross bar 92 is fixedly connected between the U-shaped frame 93 and the inner wall of the water storage tower 1.

[0027] In this embodiment, during operation, the high-temperature steam and tail gas generated by external equipment are accelerated by the Tesla valve pipe 2 and then introduced into the stirring mechanism 7. It should be noted that a gas storage tank or an air-increasing pump for pressurizing the gas can also be provided between the Tesla valve pipe 2 and the external equipment. The purpose is to be able to transport the steam and tail gas to the stirring mechanism 7 in a relatively high-pressure manner, which is an existing gas pressurization technology and will not be elaborated here. The gas discharged into the riser 71 under high pressure through the Tesla valve pipe 2 can quickly enter the rotary cover 73. The gas entering the rotary cover 73 is quickly discharged through the air injection pipe 74. Under the action of centrifugal force, the rotary cover 73 rotates at a high speed inside the hollow cover 81. The rotary cover 73 drives the impeller 72 to rotate at a high speed through the riser 71, stirring the water stored inside the water storage tower 1, so that the water inside the water storage tower 1 can be heated more evenly.

[0028] Embodiment 2 Please refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 , a heat tank steam and tail gas recycling device, including all the contents of Embodiment 1. In addition, an inverted cone disk 5 is provided inside the upper part of the water storage tower 1. An air and water conveying mechanism 6 is provided between the inverted cone disk 5 and the connection mechanism 8. The high-temperature gas entering the stirring mechanism 7 can be discharged into the air and water conveying mechanism 6 through the connection mechanism 8 for circulation, so as to be able to exchange heat with the water inside the water storage tower 1. Moreover, the stirring mechanism 7 in a rotating state can stir the water inside the water storage tower 1, so that the water inside the water storage tower 1 can circulate up and down through the air and water conveying mechanism 6.

[0029] Specifically, the air and water guiding mechanism 6 includes multiple groups of spiral air ducts 61 that are annularly arrayed and distributed below the inverted cone disk 5. A return water pipe 62 is sleeved through the inside of the spiral air duct 61. A gap is provided between the return water pipe 62 sleeved inside the spiral air duct 61 and the inner wall of the spiral air duct 61 for air flow. The lower port of the spiral air duct 61 is fixedly sealed with the outer wall of the return water pipe 62.

[0030] Furthermore, the upper port of the spiral air duct 61 is fixedly connected to the outer wall of the inverted cone disk 5. The return port 622 at the top of the return water pipe 62 penetrates through the concave surface of the inverted cone disk 5. As Figure 8 shown, the return ports 622 on multiple return water pipes 62 are annularly arrayed along the curved surface. The water outlet 621 at the bottom end of the return water pipe 62 is located below the impeller 72. The spiral air duct 61 is fixedly connected and communicated with the bottom of the exhaust pipe 3 through an arc-shaped pipe 64.

[0031] Even further, the air and water guiding mechanism 6 further includes a converging and conveying assembly 63. The converging and conveying assembly 63 includes a gas distribution pipe 631 fixedly connected between the circular ring 91 and the hollow column 82. The gas distribution pipe 631 is communicated with the hollow column 82. The gas distribution pipe 631 is fixedly connected and communicated with the outer wall of the lower side of the spiral air duct 61 through a straight pipe 635. A liquid storage box 632 is fixedly connected to the outer wall of the gas distribution pipe 631. A drain pipe 633 is fixedly connected to the bottom of the liquid storage box 632. One end of the drain pipe 633 penetrates through the outer wall of the water storage tower 1 and is threadedly connected with an end cap 634.

[0032] In this embodiment, during the rotation of the impeller 72, the water flow inside the water storage tower 1 is as Figure 12 shown. The water inside the water storage tower 1 can roll and circulate up and down. The water on the upper side can enter the inverted cone disk 5 and enter the inside of the return water pipe 62 through the return ports 622 distributed on the concave surface of the inverted cone disk 5, and finally be discharged through the water outlet 621, and then, the cycle of rolling and circulation is carried out again.

[0033] The gas discharged into the inside of the hollow cover 81 through the air injection pipe 74 is discharged into the inside of the hollow column 82 through the hollow cylinder 83. After that, the gas inside the hollow column 82 is shunted through the gas distribution pipe 631. At this time, the end cap 634 seals one end of the drain pipe 633, so that the gas inside the gas distribution pipe 631 can be conveyed to the inside of the spiral air duct 61 through the straight pipe 635, so that the high-temperature gas circulates inside the spiral air duct 61, so that the high-temperature gas can not only heat the outer wall of the spiral air duct 61, but also heat the outer wall of the return water pipe 62, significantly improving the heat exchange degree of the water and significantly improving the utilization efficiency of the hot air flow. During the heat exchange process, once the hot air flow inside the spiral air duct 61 is precooled to form water vapor and finally condenses into water droplets, the water droplets will flow along the inner wall of the spiral air duct 61 through the straight pipe 635 into the gas distribution pipe 631 and gather into the liquid storage box 632 for storage. The accumulated water can be discharged by removing the end cap 634 at regular intervals.

[0034] Example 3 Please refer to Figure 1 and Figure 2 a hot tank steam tail gas recycling device, including all the contents of Example 2. In addition, a gas storage cavity 13 is provided inside the outer shell of the water storage tower 1. A exhaust pipe 3 is fixedly connected to the center of the inverted cone plate 5, which is used to export the gas flowing in the gas and water guiding mechanism 6 into the gas storage cavity 13. The inner wall of the water storage tower 1 is fixedly connected to a suspension rod 4 for supporting the exhaust pipe 3. An outlet pipe 11 communicating with the inside of the water storage tower 1 is fixedly installed on the outer wall of the water storage tower 1, and the water heat-exchanged inside the water storage tower 1 can be discharged through the outlet pipe 11 and put into use. An outlet pipe 12 communicating with the gas storage cavity 13 is fixedly installed on the outer wall of the water storage tower 1, which can be used to release and empty the air flow in the gas storage cavity 13.

[0035] Working principle and usage process: When working, the high-temperature steam and tail gas generated by external equipment are accelerated by the Tesla valve pipe 2 and then introduced into the stirring mechanism 7. It should be noted that a gas storage tank or gas booster pump for pressurizing the gas can also be provided between the Tesla valve pipe 2 and the external equipment, aiming to be able to transport the steam and tail gas to the stirring mechanism 7 in a relatively high-pressure manner. This is an existing gas pressurization technology and will not be elaborated here too much.

[0036] The gas discharged into the vertical pipe 71 under high pressure through the Tesla valve pipe 2 can quickly enter the rotating cover 73. The gas entering the rotating cover 73 is quickly discharged through the impact pipe 74. Under the action of centrifugal force, the rotating cover 73 rotates at a high speed inside the hollow cover 81. The rotating cover 73 drives the impeller 72 to rotate at a high speed through the vertical pipe 71, stirring the water stored inside the water storage tower 1, so that the water inside the water storage tower 1 can be heated more evenly. And, during the rotation of the impeller 72, the water flow inside the water storage tower 1 is like Figure 12 shown, the water inside the water storage tower 1 can roll up and down in a cycle, and the upper water can enter the inverted cone plate 5 and enter the return water pipe 62 through the return ports 622 distributed on the concave surface of the inverted cone plate 5, and finally be discharged through the water outlet 621, and then, the cycle of rolling up and down is carried out again.

[0037] Please refer to Figure 8 、 Figure 9 and Figure 10, the gas discharged into the inner side of the hollow cover 81 through the air supply pipe 74 is discharged into the interior of the hollow column 82 through the hollow tube 83. After that, the gas inside the hollow column 82 is shunted by the sub-air pipe 631. At this time, the end cover 634 blocks one end of the liquid discharge pipe 633, so that the gas inside the sub-air pipe 631 can be transported to the inside of the spiral air guide pipe 61 through the straight tube 635, enabling the high-temperature gas to flow inside the spiral air guide pipe 61. In this way, the high-temperature gas can not only heat the outer wall of the spiral air guide pipe 61, but also heat the outer wall of the return water pipe 62, significantly improving the heat exchange degree of water and significantly improving the utilization efficiency of the hot air flow.

[0038] During the heat exchange process, once the hot air flow inside the spiral air guide pipe 61 is pre-cooled to form water vapor and finally condenses into water droplets, the water droplets will enter the sub-air pipe 631 through the straight tube 635 along the inner wall of the spiral air guide pipe 61 and gather in the liquid storage box 632 for storage. The accumulated water can be discharged regularly by removing the end cover 634.

[0039] The gas flowing inside the spiral air guide pipe 61 finally converges into the bottom of the exhaust pipe 3 through the arc-shaped pipe 64 and is transported to the inside of the gas storage cavity 13 opened in the outer shell of the water storage tower 1 through the exhaust pipe 3 to heat and keep warm the entire tower body.

[0040] It should be noted that the circuits, electronic components, and modules involved in the present invention are all prior arts, which can be fully realized by those skilled in the art without further elaboration. The content protected by the present invention does not involve improvements to software and methods either.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
