Description

A water-saving cooling tower and condensing equipment thereof

Technical Field

The utility model belongs to the technical field of water-saving cooling towers, and more specifically relates to a water-saving cooling tower and condensing equipment thereof.

Background Art

Cooling towers can be divided into mechanical ventilation cooling towers and natural ventilation cooling towers according to the ventilation method inside the tower. Thermal power plants usually use mechanical ventilation cooling towers. When they are working, circulating water is sprayed onto the filler through the nozzle of the water distribution pipe, and then falls into the water collection tank after heat exchange and cooling with the rising air. The air in the tower enters from the air inlet, and after contacting and transferring heat with the evaporating hot water in the tower, it becomes saturated hot and humid air, and is discharged to the ambient atmosphere through the water collector, fan and tower outlet.

However, a recognized disadvantage of cooling towers is that under certain atmospheric conditions, water from the hot water source evaporates and is carried into the air flow from the top of the cooling tower to produce a plume. Where cooling towers are very large (such as in thermal power plants), the plume can cause low-lying fog near the cooling tower. The plume can also form ice on roads near cooling towers, where the lower temperatures can cause the water in the plume to freeze, also wasting a lot of water resources.

In order to achieve the purpose of defogging, some related solutions have been explored in the prior art, including arranging a condensation module (or defogging module) in the cooling tower to condense the upward hot and humid air, thereby achieving the effect of defogging and water saving. The above solution can be found in the following Chinese patent documents, such as Chinese patent document, application number 2023110496074, which discloses a new type of condensing defogging cooling tower, which increases the defogging and water saving effect by optimizing the condensation module structure in the tower, reducing the liquid film thickness, increasing the effective heat exchange area, and improving the comprehensive heat transfer coefficient, effectively solving the problem of limited defogging and water saving effect of the condensation module in the cooling tower.

However, the above scheme mainly explores the improvement of the condensation module structure, increases the heat exchange area, and thus optimizes the condensation effect. The cooling air of the dry cooling channel is introduced from the upper louver. On the one hand, it will destroy the original gas flow field inside the cooling tower and affect the evaporation heat exchange effect of the cooling tower itself; on the other hand, if it is necessary to ensure the normal entry of cooling air from the louver at the bottom of the cooling tower, it is usually necessary to increase the power of the fan to achieve this. This will undoubtedly increase the energy consumption of the cooling tower, which is not conducive to environmental protection and promotion.

The utility model is further described below in conjunction with embodiments.

Example

In the first aspect, the embodiment of the present application provides a condensing device, which is located between the water distribution unit 440 and the fan 410, and is used to intercept the rising hot and humid steam and condense it. In this embodiment, the condensing device is composed of multiple groups of condensing body 500 modules, and the condensing device covers the cross-section of the entire tower body, ensuring that all hot and humid air flowing upward must pass through the condensing body 500 modules and exchange heat with the dry cold air flowing through the condensing body 500 modules, thereby reducing the moisture in the hot and humid air, effectively eliminating the white fog phenomenon, and achieving the purpose of water saving. The condensing device can be installed on the load-bearing components inside the cooling tower 400, such as the water collector beam, to achieve stable installation.

In this embodiment, the condensing body 500 is provided with mutually independent hot and humid channels and dry and cold channels 405. The hot and humid channels are connected to the inside of the cooling tower 400, and are used to transport hot and humid air into the condensing body 500; the dry and cold channels 405 are connected to the cold air inlet 460 on the cooling tower 400, and are used to transport cold air outside the tower into the condensing body 500. The main function of the condensing body 500 is to exchange heat in the hot and humid air entering the hot and humid channels through the cooling medium connected to the hot and humid channels, so as to realize cross heat exchange processing of the two air streams, and the two air streams may be in contact for heat exchange, or may not be in contact for heat exchange.

It should be noted that, since the temperature of the cold air outside the tower is lower than that of the hot and humid air at the condensation body 500 in the tower, the temperature difference is used to realize the self-priming introduction of dry cold air, and no additional energy consumption is required throughout the process, which can achieve the purpose of energy saving while saving water and eliminating fog. The cooling medium in the condensing equipment in the prior art is usually transported by a pump body or increasing the power of the fan 410, which additionally increases the energy consumption of the system. The usual idea of setting a condensing device inside the cooling tower 400 in the prior art is to add a shutter to the upper part of the cooling tower 400, and then introduce the cold air through the shutter on the upper part. This move is not only easy to interfere with the gas flow field inside the cooling tower 400, affecting the evaporation heat exchange efficiency of the cooling tower 400, but also requires additional energy consumption, which is not conducive to energy saving and environmental protection.

As another example, there are two dry cooling channels 405, which are symmetrically arranged on both sides of the condensing body 500, wherein each dry cooling channel 405 is respectively connected to the cold air inlet 460 on the same side, which can effectively improve the condensation heat exchange efficiency. The cold air inlet 460 here is the shutter provided at the lower part of the cooling tower 400, from which the cold air enters the interior of the cooling tower 400, thereby realizing the cooling treatment of the hot water sprayed above. On the one hand, the shutter provided inside the cooling tower 400 is used as the cold air inlet 460, which reduces the additional processing and installation procedures; on the other hand, it can also effectively avoid affecting the air flow field inside the cooling tower 400.

Specifically, in this embodiment, dry cold air inlets 520 are symmetrically arranged on both sides of the condensing body 500, and the output end of the dry cold channel 405 is connected to the dry cold air inlet 520. The condensing device of this embodiment can not only realize the condensation treatment of the rising hot and humid air to achieve the purpose of defogging and energy saving, but also ensure the normal flow of gas inside the cooling tower 400, without affecting the evaporation heat exchange efficiency of the cooling tower 400, and will not increase the energy consumption of the fan 410, and has good economy and practicality.

In some feasible embodiments, the condensation body 500 has a heat exchange chamber 501 inside, and the heat exchange chamber 501 is provided with a dry cold channel 405 connected to the inside of the heat exchange chamber 501, which is used to transport dry cold air to the heat exchange chamber 501. As shown in FIG. 1, in this embodiment, the condensation body 500 is provided with a wet hot channel connected to the inside of the heat exchange chamber 501 on the side away from the fan 410, which is used to transport wet hot air to the heat exchange chamber 501, and the other side of the condensation body 500 close to the fan 410 is provided with an outlet channel connected to the inside of the cooling tower 400. The two streams of air cross-flow in the heat exchange chamber 501 and perform contact heat exchange. After the heat exchange, the temperature of the wet hot air is reduced, and the condensed water formed by the condensation of water vapor flows downward for recovery. After the two streams of air after the condensation body 500 are evenly mixed and heat exchanged and condensed, the humidity in the original wet hot air is reduced, and then discharged to the outside of the tower from the fan 410, which can achieve fog elimination and water saving.

In some achievable embodiments, an air inlet condensation plate 510 is provided on the side of the heat exchange chamber 501 facing away from the fan 410, and a humid heat passage communicating with the interior of the cooling tower 400 is provided on the air inlet condensation plate 510; the air inlet condensation plate 510 is used to seal the heat exchange chamber 501 from the bottom, and intercept and condense the humid heat air rising from the interior of the cooling tower 400. An air outlet condensation plate 504 is provided on the other side of the heat exchange chamber 501 close to the fan 410, and an air outlet passage communicating with the interior of the cooling tower 400 is provided on the air outlet condensation plate 504; the air outlet condensation plate 504 is used to seal the heat exchange chamber 501 from the top, and the humid heat air after condensation and heat exchange in the heat exchange chamber 501 is discharged from the air outlet passage.

As shown in FIG. 3 and FIG. 4 , in this embodiment, the air inlet condensation plate 510 and the air outlet condensation plate 504 are both made of porous materials, and the wet heat channel and the air outlet channel are pore channels inside the porous materials. At the same time, a heat exchange tube 503 is arranged in the heat exchange chamber 501, and the heat exchange tube 503 is clamped between the condensation plates on both sides, and the condensation plates on both sides are embedded in the installation frame 505. In this embodiment, the outer surface of the heat exchange tube 503 is evenly surrounded by a plurality of air exchange holes 511, which are used to input cold air into the heat exchange chamber 501, and cool down the condensation plates on both sides to increase the condensation effect.

In practice, the porous material can be foam metal or non-metal foam, wherein the foam metal is any one of foam nickel, foam aluminum, foam copper or foam aluminum alloy; the non-metal foam is any one of filter sponge, biochemical sponge, activated carbon sponge or carbon fiber sponge.

It should be noted that, in some examples, the inlet condensation plate 510 and the outlet condensation plate 504 may also be a grid structure or a grille structure; or the surfaces of the inlet condensation plate 510 and the outlet condensation plate 504 may be provided with ventilation holes 511. As long as the hot and humid air can penetrate the heat exchange chamber 501 and be condensed by the cold air, it will be fine.

In some examples, as shown in FIG. 7 and FIG. 8 , a plurality of partitions 502 are provided inside the heat exchange chamber 501 in this embodiment to separate the heat exchange chamber 501 into a plurality of independent spaces; each independent space is connected to the dry cooling channel 405, and the dry cooling channel 405 is used to transport dry cooling air to each independent space. Specifically, in this embodiment, each independent space is provided with an inlet pipe 530 connected to the interior thereof, and the inlet pipe 530 on the same side is connected to the dry cooling channel 405 through a connecting pipe 540.

It can be understood that in this embodiment, the side of the condensation body 500 facing away from the fan 410 is an open structure, and the other side of the condensation body 500 close to the fan 410 is an open structure. The axial ends of the condensation body 500 along the cooling tower 400 can have one end as an open structure and the other end as a channel connected to the outside of the condensation body 500 (i.e., the inside of the cooling tower 400); or both ends of the condensation body 500 can be open structures.

In some examples, as shown in FIG9 , in this embodiment, a plurality of heat exchange tubes 503 are arranged at intervals inside the heat exchange chamber 501, and each heat exchange tube 503 is connected to the dry cold channel 405. The hot and humid air enters the heat exchange chamber 501 through the hot and humid channel and performs heat exchange and condensation with the dry cold air in the heat exchange tube 503. If the heat exchange tube 503 is not provided with a heat exchange channel connected to the outside of the tube, the hot and humid air performs non-contact heat exchange and condensation with the dry cold air in the tube. If the heat exchange tube 503 is provided with a heat exchange channel connected to the space outside the tube, the dry cold air enters the heat exchange chamber 501 through the heat exchange channel and performs contact heat exchange and condensation with the hot and humid air.

In some examples, the heat exchange channel is an air exchange hole 511, and the air exchange hole 511 is arranged on at least part of the outer surface of the heat exchange tube 503. The structure of the heat exchange hole 511 is not limited to a circular through-hole structure, and can also be an elliptical hole structure or other regular or irregular hole structures. Preferably, the heat exchange holes 511 are evenly distributed around the outer surface of the heat exchange tube 503, which can achieve uniform output of cold air and a relatively stable output airflow. It is understandable that the heat exchange channel can be replaced with a grid-type hollow structure or a round-shaped groove structure.

In some examples, as shown in FIG10 , a condensing plate 510 is provided on the side of the condensing body 500 facing away from the fan 410 in this embodiment, and the condensing plate 510 is a grid structure or a grille structure, or the surface of the condensing plate 510 is provided with ventilation holes 511. It should be noted that in other examples, a top plate is provided on the side of the condensing body 500 close to the fan 410, wherein the top plate has the same structure as the condensing plate, and may also be a grid structure or a grille structure, or the surface of the top plate may be provided with ventilation holes 511.

In order to control the flow rate of dry cold air, in some examples, a control valve is provided on the dry cold channel 405, and a pressure gauge and a temperature gauge are provided on the dry cold channel 405 to adjust the speed and flow of air entering the condensing device to further improve the condensation efficiency. It is also possible to consider setting high-efficiency heat exchange materials in the heat exchange chamber 501 and the dry cold channel 405 to improve the heat exchange efficiency, and regularly clean and maintain 501 and the dry cold channel 405 to ensure efficient operation. The condensing equipment can adopt a modular design, and different components can be selected according to actual needs, which can not only reduce costs, but also facilitate equipment upgrades and improvements.

In the second aspect, the embodiment of the present application provides a water-saving cooling tower, wherein a condensation area 430 is provided inside the cooling tower 400, and the condensation area 430 is located between the water distribution unit 440 and the fan 410, and the above-mentioned condensation equipment is provided in the condensation area 430. The humid and hot air discharged is collected by adding the condensation area 430, and the rising water vapor is intercepted by the condensation area 430, and the water vapor is condensed into water droplets after condensation and heat exchange in the condensation area 430, and the water droplets fall back to the packing unit 450 or the water collection tank 470 below due to their own gravity, thereby achieving the purpose of water saving and mist elimination.

It can be understood that in this embodiment, at least one layer of condensing equipment is provided in the condensing area 430; when the condensing equipment is arranged in a single-layer structure, the two ends of a single condensing equipment extend to the two ends of the cross section of the cooling tower 400; or, multiple condensing bodies 500 are arranged in a single layer and are arranged at intervals along the length or width direction of the cooling tower 400. Referring to FIG. 2 , when the condensing equipment is arranged in a double-layer or higher structure, multiple condensing bodies 500 of each layer are arranged at intervals along the cross section of the cooling tower 400, and multiple layers of condensing bodies 500 are arranged in a staggered manner, which can effectively improve the condensation heat exchange effect and improve the water collection efficiency.

During the operation of the cooling tower 400, the flow rate, spraying speed and other parameters of the cooling medium can be adjusted by the control system to achieve the best cooling heat exchange condensation effect. In this way, energy consumption can be further reduced and the condensation heat exchange efficiency can be improved. In summary, the condensing equipment and cooling tower of the present application are scientifically and reasonably designed, can play an important role in industrial production and other fields, can help users reduce operating costs and improve the overall efficiency of the system.
