Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a low-carbon fog-eliminating and water-saving cooling tower. Background Art

[0002] Cooling towers are the core equipment for industrial circulating water cooling in industrial production and daily life in industries such as petroleum, chemical, electric power, metallurgy, new materials, new energy, and waste incineration. There are a large number of high-temperature process media that need to be cooled in process industries. The most commonly used method is to use industrial circulating cooling water to cool the high-temperature medium to meet the temperature required by the process. After the industrial circulating cooling water passes through the heat exchange equipment, it becomes low-enthalpy industrial circulating hot water. It is necessary to use cooling equipment to cool the circulating water in order to achieve the recycling of cooling water, save a lot of water resources, and reduce production costs.

[0003] Cooling towers are the most commonly used cooling equipment in industry for cooling low enthalpy industrial cycles. However, conventional cooling towers will produce a large amount of "plume mist" (commonly known as "white mist" or "white smoke") during the cooling process and emit it into the atmosphere, which on the one hand causes a waste of water resources and on the other hand causes adverse effects on the environment. Summary of the invention

[0004] The technical problem to be solved by the utility model is: in order to solve the "white fog" and water resource waste problems of the existing cooling tower and reduce the energy consumption of the cooling tower, the utility model provides a low-carbon demisting and water-saving cooling tower, strengthens the demisting and water-collecting effect, improves the demisting and water-saving performance of the cooling tower, and at the same time utilizes solar energy and temperature difference power generation as the energy source of the system power equipment to realize the self-supply of electricity for the cooling tower.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a low-carbon fog-eliminating and water-saving cooling tower, comprising a tower body, a bionic fiber membrane, a condensing device, a semiconductor temperature difference power generation module, a ceramic oblique staggered filler, a circulating water outlet pipe, a tower bottom battery, a water collection tank, a photovoltaic power generation panel power supply device, a circulating water inlet pipe, a sprinkler, a tower top battery, a DC to AC converter, a fan, and an air inlet.

[0006] Furthermore, the bionic fiber membrane has a fluffy structure and is composed of a bionic phospholipid layer of a polymer material. The bionic fiber membrane consists of a water-absorbing head and a hydrophobic tail, and is used to absorb condensed water and drip down along the hydrophobic tail. The bionic fiber membrane is arranged in a transverse staggered array and is located above the condensation device, with the four sides clamped on the inner side of the tower wall to form a second condensation and demisting barrier.

[0007] Furthermore, the cooling water pipe of the condensing device is designed in a multi-layer winding manner, and the condensing ball is sleeved on the cooling water pipe. The cooling water pipe has a water inlet and a spray port, and the spray port is located at the bottom layer below the condensing ball. The condensing ball on the cooling water pipe not only increases the condensation heat exchange area between the cooling water in the pipe and the humid hot air ascending in the tower, but also intercepts the water droplets carried by the humid hot air, forming the first condensation defogging barrier, and strengthening the condensation defogging water-saving effect; at the same time, the cold air coming in from the air inlet of the tower wall is mixed with the humid hot air in the tower for heat exchange, further strengthening the condensation defogging water-saving effect.

[0008] Furthermore, the semiconductor temperature difference power generation module, the low-temperature module is fixed at the bottom of the cooling tower, in the low-temperature cold source area, and the high-temperature module is located below the sprinkler, in the high-temperature heat source area, and the two ends are connected by a polymer material rod; a vent is set in the center of the polymer material rod, and the bottom end is connected to a wire, and the wire is connected to the battery at the bottom of the tower. The low-temperature module and the high-temperature module are also provided with vents to reduce the impact of the semiconductor temperature difference power generation module on the flow of gas in the tower body; the semiconductor temperature difference power generation module utilizes the heat of hot water and the temperature difference directly formed by cooling water to generate electrical energy according to the Seebeck effect, and transmits it to the battery at the bottom of the tower, and the battery at the bottom of the tower serves as a power supply device for the DC-AC converter.

[0009] Furthermore, the ceramic obliquely staggered filler is arranged in layers of obliquely staggered fillers, bonded and connected with quick-drying glue to form a channel, placed below the high-temperature module in the semiconductor temperature difference power generation module, and placed on a welded slot bracket. The ceramic obliquely staggered filler is corrosion-resistant, acid-resistant, alkali-resistant, and antifreeze-resistant, and has good heat exchange performance.

[0010] Furthermore, the photovoltaic panel power supply device is attached to the outer wall of the tower body, connected to a DC / AC converter, and then connected to a tower top battery to provide power for the tower top wind turbine, thereby reducing the energy consumption of the wind turbine.

[0011] Furthermore, air inlets are arranged around the tower wall of the bionic fiber membrane, air inlets are also arranged around the tower wall of the condensing device, and air inlets are also arranged under the ceramic obliquely staggered filler; air inlets are arranged in the areas where the ceramic obliquely staggered filler, the condensing device and the bionic fiber membrane in the tower involve heat exchange, and humid hot air and fresh air are cooled and exchanged with heat, and the temperature of the humid hot air is further reduced, which greatly enhances the heat exchange and defogging and water-saving effects of the cooling tower.

[0012] Furthermore, the circulating water inlet pipe is connected to the tower body from below the spray port of the condensing device, so that industrial hot water flows into the cooling tower. The sprinkler is connected to the terminal of the circulating water inlet pipe, and the sprinkler coverage area is approximately equal to the internal surface area of ​​the cooling tower.

[0013] Furthermore, the wind turbine is connected to a tower top battery, the tower top battery is located in the middle position below the wind turbine, and the DC / AC converter is connected to the tower bottom battery.

[0014] Furthermore, the water collecting tank is arranged at the bottom of the tower body, and a circulating water outlet pipe is arranged to lead to the outside of the tower body.

[0015] The beneficial effects of the utility model are:

[0016] (1) The condensing device in the technical solution is the first condensation and defogging process. The condensing ball not only increases the condensation heat exchange area between the cooling water in the tube and the humid hot air ascending in the tower, but also intercepts the water droplets carried by the humid hot air, thereby enhancing the condensation defogging and water-saving effect. When the cooling water flows downward through the spray port, it mixes with the humid hot air in the area above the ceramic oblique staggered packing for heat exchange, thereby improving the heat exchange effect.

[0017] (2) The bionic fiber membrane in the technical solution is the second condensation and defogging process. The bionic fiber membrane is a fluffy type with a water-absorbing surface. It can absorb water droplets in the plume and then drop them down into the water collection pool along the hydrophobic tail through gravity, further intercepting water droplets in the upward hot and humid air in the tower to achieve the purpose of collecting water, which can greatly improve the defogging and water collection efficiency.

[0018] (3) The ceramic oblique staggered packing in the technical solution is corrosion-resistant, acid- and alkali-resistant, antifreeze-resistant, has low flow resistance, good heat exchange performance, and long service life;

[0019] (4) The photovoltaic panel power supply device in the technical solution converts solar energy into electrical energy to directly power the fan and water pump, making the equipment self-sufficient in electricity, eliminating the need for external power supply and reducing energy consumption;

[0020] (5) The semiconductor temperature difference power generation module in the technical solution absorbs the heat emitted by hot water, generates a temperature difference, converts thermal energy into electrical energy to provide electricity, further improves energy utilization and reduces energy consumption.

[0027] The utility model is now described in further detail in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, so they only show the components related to the utility model, and the directions and references (for example, up, down, left, right, etc.) can only be used to help describe the features in the drawings. Therefore, the following specific embodiments are not adopted in a restrictive sense, and the scope of the subject matter for which protection is sought is limited only by the attached claims and their equivalents.

[0030] Bionic fiber membrane 2, see Figure 3 It has a fluffy structure and is composed of a bionic phospholipid layer of a polymer material. The bionic fiber membrane is composed of a water-absorbing head 201 and a hydrophobic tail 202. The bionic fiber membrane 2 is arranged in a transverse staggered array and is arranged above the condensing device 3. It is clamped on the inner side of the tower wall on all sides to form a second condensation and defogging barrier. The fluffy water-absorbing head 201 will absorb moisture, and due to the effect of gravity, it will flow downward along the hydrophobic tail 202 and finally fall into the water collection pool 8 to be collected, thereby reducing the generation of "feather mist" and further improving the defogging and water-saving effect of the cooling tower.

[0031] Condensing device 3, see Figure 4The cooling water pipe 303 is designed with multiple layers of winding, and the condensation ball 302 is sleeved on the cooling water pipe 303. The cooling water pipe 303 has a water inlet 301 and a spray port 304. The spray port 304 is located at the bottom layer below the condensation ball 302. The condensation ball 302 is sleeved on the cooling water pipe 303, which increases the condensation heat exchange area between the cooling water in the pipe and the humid hot air ascending in the tower. At the same time, it can intercept the water droplets carried by the humid hot air to form the first condensation defogging barrier, thereby enhancing the condensation defogging and water-saving effect; the cooling water flowing out of the spray port 304, in the process of the cooling water floating downward through the spray port 304, is mixed with the humid hot air in the upper area of ​​the ceramic oblique staggered filler 5 for heat exchange, thereby improving the heat exchange effect; at the same time, it can also participate in the heat exchange process of the ceramic oblique staggered filler 5, and the condensation device 3 will cool the humid hot steam and condense it into a liquid and fall, and be collected by the water collection tank 8.

The low temperature module 402 and the high temperature module 401 are also provided with a vent 405 to reduce the influence of the semiconductor temperature difference power generation module 4 on the flow of gas in the tower body 1; the semiconductor temperature difference power generation module 4 uses the heat of hot water and the temperature difference directly formed by cooling water to generate electrical energy according to the Seebeck effect, and transmits it to the tower bottom battery 7, and the tower bottom battery 7 serves as a power supply device for the DC-AC converter 13 and the water pump in the system.

[0033] The ceramic oblique staggered filler 5 is in the form of an oblique staggered stacking arrangement, and is bonded and connected by quick-drying glue to form a channel, which is placed below the high-temperature module 401 in the semiconductor temperature difference power generation module 4 and placed on a welded slot bracket. The ceramic oblique staggered filler 5 has the characteristics of corrosion resistance, acid and alkali resistance, antifreeze, and good heat exchange performance. When hot water is sprayed out by the sprinkler 11, it will first enter the ceramic oblique staggered filler 5. The oblique staggered stacking design reduces the channel resistance, increases the liquid flow rate, and thus improves the condensation efficiency;

[0034] The photovoltaic panel power supply device 9 is attached to the outer wall of the tower body 1, connected to the DC / AC converter 13, and then connected to the tower top battery 12 to provide power for the tower top fan 14, thereby reducing the energy consumption of the fan operation.

[0035] The circulating water inlet pipe 10 is connected to the tower body 1 from below the spray port 304 of the condensing device 3, so that industrial hot water flows into the cooling tower. The sprinkler 11 is connected to the circulating water inlet pipe terminal 10. The coverage area of ​​the sprinkler 11 is approximately equal to the internal surface area of ​​the cooling tower, and the hot water required for cooling entering from the circulating water inlet pipe 10 is sprayed.

[0036] In order to further enhance the heat exchange and defogging and water-saving effects of the cooling tower, air inlets 15-1 and 15-6 are arranged around the tower wall of the bionic fiber membrane 2, and air inlets 15-2 and 15-5 are also arranged around the tower wall of the condensing device 3, and air inlets 15-3 and 15-4 are also arranged under the ceramic oblique staggered filler 5; the areas where the ceramic oblique staggered filler 5, the condensing device 3 and the bionic fiber membrane 2 in the tower involve heat exchange are all provided with air inlets 15, and humid hot air and fresh air are cooled and exchanged with heat, and the temperature of the humid hot air is further reduced, which greatly enhances the heat exchange and defogging and water-saving effects of the cooling tower.

[0037] The fan 14 is connected to the tower top battery 12, and the tower top battery 12 is located in the middle position below the fan 14. The DC-AC converter 13 is connected to the tower bottom battery 12, and the DC-AC converter 13 is provided with power by the tower bottom battery 7. The water collection tank 8 is arranged at the bottom of the tower body 1, and a circulating water outlet pipe 6 is arranged to the outside of the tower body 1, so that the cooled industrial hot water flows out of the cooling tower.

[0038] In detail, the working principle of a low-carbon mist elimination and water-saving cooling tower is as follows: dry cold air enters the cooling tower from the air inlets 15-1, 15-2, 15-3, 15-4, 15-5, and 15-6 under the pumping of the fan 14, and the industrial hot water required for cooling flows from the circulating water inlet pipe 10 to the sprinkler 11, and is sprayed into the tower from the sprinkler 11. When the wet hot water droplets and the dry cold air contact the ceramic oblique staggered filler 5 in the cooling tower, heat exchange is performed to achieve the purpose of heat exchange cooling; the wet hot air flows upward, first passes through the condensing device 3, exchanges heat with the cooling water flowing inside it, and is cooled as droplets and falls down, and the wet hot steam that has not been completely cooled continues to rise and passes through the bionic fiber membrane 2. The water droplets are adsorbed by the water absorption head 201 and fall along the hydrophobic tail 202 due to gravity, completing condensation and defoggering. The cooled water droplets flow downward and are collected by the water collection tank 8, and finally the cooled industrial hot water flows out from the circulating water outlet pipe 6; the hot water in the sprinkler 11 area generates hot steam and forms a temperature difference with the bottom of the tower, and the semiconductor temperature difference power generation module 4 generates electricity and is collected by the battery 7 at the bottom of the tower as the power source of the DC-AC converter 13. After the photovoltaic power generation device 9 on the surface of the tower body 1 completes the DC-AC conversion, the electric energy is stored in the battery 12 on the top of the tower to power the fan 14. A low-carbon defogging and water-saving cooling tower achieves the purpose of low-carbon defogging and water-saving of the cooling tower through the above-mentioned working principle.

[0039] In detail, the heat exchange principle of a low-carbon mist elimination and water-saving cooling tower is as follows: the cooling water in the cooling water pipe 303 of the condensing device 3 exchanges heat with the hot and humid air outside the pipe, and the water in the hot and humid air outside the pipe is intercepted by the condensation ball 302, and at the same time, the water vapor in the hot and humid air is condensed into water on the condensation ball 302; the rising hot and humid air exchanges heat with the fresh dry and cold air in the bionic fiber membrane 2; the cooling water in the pipe sprayed from the spray port 304 and the cooling water condensed and falling from the bionic fiber membrane 2 are mixed with the industrial hot water sprayed from the sprinkler 11 for heat exchange; the industrial hot water and the dry and cold air exchange heat in the ceramic oblique staggered filler 5.
