Description

A high-temperature flue gas aeration cooling tower Technical Field

[0001] This application relates to the field of cooling tower technology, specifically a high-temperature flue gas aeration cooling tower. Background Technology

[0002] Cooling towers play a vital role and are an indispensable piece of equipment in many large factories, shopping malls, and thermal power plants. They facilitate heat exchange between cooling water carrying waste heat and the air inside the tower, transferring the waste heat to the air and dissipating it into the atmosphere.

[0003] An existing patent (publication number: CN219551251U) discloses a water-circulating cooling tower, including a cooling tower body, a sliding plate slidably connected to the cooling tower body, a lead screw mounted on the sliding plate and connected to an external motor, causing the sliding plate to reciprocate along the cooling tower body in the horizontal longitudinal direction to adjust the cooling position of the object, a liquid guiding system disposed between the cooling tower body and the sliding plate for collecting the cooled water flow, a liquid supply system symmetrically disposed on both sides of the cooling tower body, the liquid supply system communicating with the liquid guiding system, and the spray end of the liquid supply system being arranged at the top of the cooling tower body, and an exhaust system symmetrically installed on the cooling tower body, the exhaust system covering the liquid supply part of the liquid supply system; it can spray and cool the object relatively comprehensively, and during cooling, the air guiding process can be adjusted according to changes in external temperature, so that the cooling tower can effectively prevent the liquid from freezing due to low external ambient temperature, thereby ensuring normal circulation.

[0004] The device in the aforementioned comparative document uses a single-layer spray method to achieve the cooling effect. However, the cooling effect of the single-layer spray method is limited. In order to further optimize the applicability of the device, a high-temperature flue gas aeration cooling tower is proposed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this application provides a high-temperature flue gas aeration cooling tower that achieves deep cooling of flue gas and efficient utilization of water resources through a synergistic design of symmetrical air intake through dual flues and differentiated spraying between upper and lower layers.

[0006] To achieve the above objectives, this application provides the following technical solution: a high-temperature flue gas aeration cooling tower, comprising an aeration tank, a cooling tower body, an aeration component, a cooling component, a fan, and a honeycomb ceramic packing module. The aeration component includes two exhaust hoods fixedly connected to the outer surface of the cooling tower body. The aeration tank is provided with uniformly distributed aeration pipes inside, and the two ends of the plurality of aeration pipes are respectively connected to the interior of the two exhaust hoods.

[0007] The cooling assembly includes a first liquid pump and a second liquid pump. The first and second liquid pumps are respectively connected to the interior of the aeration tank through pipes. The output end of the first liquid pump is connected to a first water supply pipe, and the output end of the first water supply pipe is connected to an upper spray module. The upper spray module consists of multiple upper spray pipes, and each upper spray pipe has evenly distributed rotating nozzles installed on its outer surface. The output end of the second liquid pump is connected to a second water supply pipe, and the output end of the second water supply pipe is connected to a lower spray module. The lower spray module consists of multiple lower spray pipes, and each lower spray pipe has evenly distributed atomizing nozzles installed on its outer surface.

[0008] The above scheme achieves symmetrical air intake through dual flues by setting up aeration components, resulting in more efficient heat exchange. The cooling components enable multi-stage water recycling. Water is sprayed onto the interior of the cooling tower via upper and lower spray modules, achieving a double-layer spraying effect. The upper spray module uses multiple rotating nozzles to achieve high-flow, wide-area spraying, while the lower spray module uses multiple atomizing nozzles to achieve stable, high-pressure atomized spraying. The combination of rotating and atomizing nozzles effectively improves heat exchange efficiency and increases the overlap rate of the spray water curtain, preventing dry dead zones in the honeycomb ceramic packing module.

[0009] Furthermore, the cooling tower body is fixedly connected to the inner bottom wall of the aeration tank by a bracket, and the fan is installed at the bottom of the cooling tower body.

[0010] The above scheme defines the relationship between the aeration tank and the cooling tower body, allowing the water sprayed in the cooling tower body to flow back into the aeration tank, facilitating water recycling. The installed fan facilitates the rise of high-temperature flue gas inside the cooling tower body, which is beneficial for the cooling of the flue gas.

[0011] Furthermore, both the upper spray module and the lower spray module are embedded in the inner wall of the cooling tower body, with the upper spray module located above the lower spray module.

[0012] The above scheme defines the positional relationship between the upper and lower spray modules, enabling a double-layer spraying effect and further optimizing the cooling effect on the flue gas.

[0013] Furthermore, the upper and lower spray pipes are distributed alternately inside the cooling tower body.

[0014] By defining the positional relationship between the upper and lower spray pipes, the overlap rate of the upper and lower spray water curtains can be improved, preventing the formation of dry dead zones in the honeycomb ceramic filler module.

[0015] Furthermore, the honeycomb ceramic packing module is installed inside the cooling tower body, and the honeycomb ceramic packing module is located below the lower spray module.

[0016] The above scheme extends the gas-water contact time by using honeycomb ceramic packing modules, thereby improving the flue gas cooling effect.

[0017] Furthermore, each of the two smoke hoods has a smoke supply pipe connected to one end of each smoke supply pipe, and a flange joint is fixedly connected to one end of each smoke supply pipe.

[0018] The above solution allows for easy connection between the exhaust hood and external flue gas emission equipment via the provided smoke supply pipe and flange joint, making it convenient to use.

[0019] Furthermore, the bottom surface of the aeration tank is fixedly connected to six support piles, and a positioning plate is fixedly connected to the bottom of each support pile.

[0020] The above method, through the installation of support piles and positioning plates, allows the aeration tank to be installed and positioned in a suitable location, thereby ensuring the stability of the aeration tank.

[0021] Furthermore, the bottom of the aeration tank is connected to a drain pipe, and the output end of the drain pipe is equipped with a sealing plug.

[0022] The above solution allows for convenient and timely replacement of the water inside the aeration tank via the drainage pipe, thus ensuring the cooling effect.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This high-temperature flue gas aeration cooling tower achieves symmetrical air intake through dual flues by setting up aeration components, resulting in more efficient heat exchange. The cooling components enable multi-stage water recycling. Water is sprayed inside the cooling tower body through upper and lower spray modules, achieving a double-layer spraying effect. The upper spray module uses multiple rotating nozzles to achieve high-flow, wide-area spraying, while the lower spray module uses multiple atomizing nozzles to achieve stable, high-pressure atomized spraying. The combination of rotating and atomizing nozzles effectively improves heat exchange efficiency and increases the overlap rate of the spray water curtain, preventing dry dead zones in the honeycomb ceramic packing module.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please refer to Figures 1, 2, and 5. This embodiment of a high-temperature flue gas aeration cooling tower includes an aeration tank 1, a cooling tower body 2, an aeration assembly 3, a cooling assembly 4, a fan 5, and a honeycomb ceramic packing module 6. The cooling tower body 2 is fixedly connected to the inner bottom wall of the aeration tank 1 via a bracket. The fan 5 is installed at the bottom of the cooling tower body 2, defining the relationship between the aeration tank 1 and the cooling tower body 2. This allows water sprayed into the cooling tower body 2 to flow back into the aeration tank 1, facilitating water recycling. The fan 5 also facilitates the efficient use of high-temperature cooling equipment. Flue gas rises inside the cooling tower body 2, which is beneficial to the cooling of the flue gas. Six support piles 7 are fixedly connected to the bottom of the aeration tank 1. Each support pile 7 is fixedly connected to the bottom of a positioning plate. The support piles 7 and positioning plates can be used to install and position the aeration tank 1 in a suitable position, thereby ensuring the stability of the aeration tank 1. The bottom of the aeration tank 1 is connected to a drain pipe 8. The output end of the drain pipe 8 is equipped with a sealing plug. The drain pipe 8 can be used to conveniently replace the water inside the aeration tank 1 at regular intervals, thereby ensuring the cooling effect.

[0034] Please refer to Figures 2, 3, and 4. The aeration assembly 3 includes two exhaust hoods 301 fixedly connected to the outer surface of the cooling tower body 2. The aeration tank 1 is equipped with evenly distributed aeration pipes 302. The two ends of the multiple aeration pipes 302 are respectively connected to the interior of the two exhaust hoods 301. After the flue gas enters from the two exhaust hoods 301, it flows into the aeration tank 1 along the multiple aeration pipes 302 and releases heat to the water inside the exhaust hoods 301 in the form of bubbles. The ends of the two exhaust hoods 301 that are far apart from each other are connected to the smoke supply pipes 303. One end of each smoke supply pipe 303 is fixedly connected to a flange joint 304. The smoke supply pipes 303 and flange joints 304 can be used to easily connect the exhaust hoods 301 to external flue gas emission equipment for convenient use. Therefore, the aeration assembly 3 can achieve a symmetrical design of the double flue. The symmetrical design of the double flue can effectively avoid ash accumulation on one side and make the flue gas aeration work more evenly.

[0035] Please refer to Figures 2, 4, and 5. The cooling assembly 4 includes a first liquid pump 401 and a second liquid pump 404. The first liquid pump 401 and the second liquid pump 404 are respectively connected to the interior of the aeration tank 1 through pipes. The output end of the first liquid pump 401 is connected to a first water supply pipe 402. The output end of the first water supply pipe 402 is connected to an upper spray module 403. The upper spray module 403 is composed of multiple upper spray pipes 4031. Each upper spray pipe 4031 has evenly distributed rotating nozzles 4032 installed on its outer surface. When the first liquid pump 401 is started, it can pump the hot water inside the aeration tank 1 to the upper spray module 403 through the first water supply pipe 402. Then, the hot water is sprayed out through the upper spray module 403 in a rotating manner. The flue gas and the spray water come into countercurrent contact in the cooling tower body 2 to achieve heat exchange. Afterward, the spray water will flow back into the aeration tank 1, thereby achieving the effect of water circulation.

[0036] Please refer to Figures 3, 4, and 5. The output end of the second liquid pump 404 is connected to the second water supply pipe 405, and the output end of the second water supply pipe 405 is connected to the lower spray module 406. The lower spray module 406 consists of multiple lower spray pipes 4061, and each lower spray pipe 4061 has evenly distributed atomizing nozzles 4062 installed on its outer surface. The upper spray pipes 4031 and the lower spray pipes 4061 are staggered inside the cooling tower body 2. When the second liquid pump 404 is started, it can transport water from the aeration tank 1 to the lower spray module 406 through the second water supply pipe 405, and the water is atomized and sprayed out through the lower spray module 406. By limiting the upper spray pipes 4031 and the lower spray pipes 4061, the water can be effectively sprayed out. The positional relationship of 061 can improve the overlap rate of the upper and lower spray water curtains and prevent the formation of dry dead zones in the honeycomb ceramic packing module 6. Both the upper spray module 403 and the lower spray module 406 are embedded in the inner wall of the cooling tower body 2. The upper spray module 403 is located above the lower spray module 406, which limits the positional relationship between the upper spray module 403 and the lower spray module 406, enabling the effect of double-layer spraying and further optimizing the cooling effect of flue gas. The honeycomb ceramic packing module 6 is installed inside the cooling tower body 2 and is located below the lower spray module 406. The honeycomb ceramic packing module 6 can extend the contact time between air and water, thereby improving the cooling effect of flue gas.

[0037] It should be noted that when the high-temperature flue gas rises, it continuously collides with the falling spray water in the honeycomb ceramic packing module 6. The heat is transferred to the water through conduction and evaporation. After absorbing the heat, the spray water partially evaporates, and the remaining cooling water falls back into the aeration tank 1.

[0038] In this embodiment, a high-temperature flue gas aeration cooling tower achieves symmetrical air intake through dual flues by setting an aeration component 3, resulting in more efficient heat exchange. The cooling component 4 enables multi-stage water recycling. Water is sprayed onto the interior of the cooling tower body 2 via an upper spray module 403 and a lower spray module 406, achieving a double-layer spraying effect. The upper spray module 403 uses multiple rotating nozzles 4032 to achieve high-flow, wide-range spraying, while the lower spray module 406 uses multiple atomizing nozzles 4062 to achieve stable, high-pressure atomized spraying. The rotating nozzles 4032 and atomizing nozzles 4062 work together to effectively improve heat exchange efficiency and increase the overlap rate of the spray water curtain, preventing dry dead zones from appearing in the honeycomb ceramic packing module 6.

[0039] The working principle of the above embodiment is as follows: High-temperature flue gas enters two exhaust hoods 301 through multiple flue gas supply pipes 303. The high-temperature flue gas in the two exhaust hoods 301 enters the exhaust hood 301 through multiple aeration pipes 302, reacting with the water in the exhaust hood 301. The high-temperature flue gas releases its residual heat in the form of bubbles. At this time, the water temperature inside the exhaust hood 301 will rise. Then, the first liquid pump 401 and the second liquid pump 404 are started respectively to pump the hot water in the exhaust hood 301 to the cooling tower body 2 for spraying. When the first liquid pump 401 is started, the hot water in the exhaust hood 301 can be transported to the upper spray module 403 through the first water supply pipe 402. The upper spray pipe 4031 and the rotating nozzle 4032 spray hot water into the cooling tower body 2. When the second liquid pump 404 is started, it can atomize the hot water in the exhaust hood 301 and spray it into the cooling tower body 2 through the lower spray pipe 4061 and the atomizing nozzle 4062. This can improve the water utilization rate and effectively prevent the honeycomb ceramic packing module 6 from having a dry dead zone, thereby improving the cooling effect. The flue gas and the spray water come into countercurrent contact in the cooling tower body 2. After completing the heat exchange, the cooling water can fall back to the aeration tank 1, thereby achieving the effect of water circulation. The fan 5 can ensure forced convection of flue gas and discharge the cooled flue gas to the outside of the environment.
