Description

Technical Field

[0001] The present application relates to the technical field of cooling towers, and in particular to a cooling tower core component. Background Art

[0002] As the demand for energy conservation and emission reduction continues to increase, cooling towers play an increasingly important role in industrial applications, especially in thermal power plants. Cooling towers use evaporative cooling technology to remove waste heat from industrial processes, maintain normal operation of equipment, and improve thermal efficiency.

[0003] Most of the cooling towers of thermal power plants have been in operation for many years since they were put into operation. During the long-term operation, the content of sediment in the circulating water is high, and the core materials of the cooling towers have silt precipitation and scaling, which seriously affects the performance of the cooling towers. Specifically, the water-spraying filler is damaged, resulting in uneven water distribution of the splash device and blocked heat exchange channels of the filler, which causes improper matching of the aerodynamic field and water flow, and ultimately leads to a significant decrease in the heat exchange efficiency of the cooling tower. The damaged core materials frequently block the inlet filter of the circulating water pump, further affecting the normal operation of the circulating water pump and seriously threatening the safety and stability of the system.

[0004] The original water-sprinkling filler material quality is poor, easy to age, break and fall off, and has poor frost resistance and short service life. At present, it has already experienced serious aging. The traditional 30mm-38mm sheet spacing S-wave, double oblique wave and oblique folded wave water-sprinkling fillers have relatively poor thermal performance and resistance characteristics. The waveform design is not optimized, and the sheet spacing is too large, resulting in a small air-water bonding area and poor heat exchange effect. At the same time, the ambient temperature is low during winter operation, and a large amount of ice appears on the core parts of the cooling tower, causing large-scale damage and fall of the cooling tower filler and bracket. The damaged or fallen filler frequently blocks the primary inlet filter of the circulating water pump, reducing the overall performance and life of the cooling tower and increasing maintenance costs. In addition, the splashing device adopts a single caliber, which has the problem of uneven splashing, reducing the uniformity of cooling water dispersion, and cannot fully utilize the internal cooling area of ​​the cooling tower, reducing the cooling effect of the cooling tower.

[0005] In summary, there is still a lot of room for improvement in the existing cooling tower core components in terms of resource utilization efficiency and stable operation of equipment. There is an urgent need for a cooling tower core component that can reduce resource waste and extend equipment life. Summary of the invention

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of this application, unless otherwise specified, "plurality" means two or more.

[0043] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0044] Example 1

[0045] Figure 1 A cooling tower core component provided in an embodiment of the present application includes: a water spraying filler layer 1, a splashing device 2, and a supporting structure 5;

[0046] The water spraying filler layer 1 is divided into an outer circle area, a middle circle area, and an inner circle area, and a filler gradient arrangement is adopted from the outer circle area to the inner circle area; the splashing device 2 adopts an air-water ratio optimized arrangement; the supporting structure 5 includes a dense fiberglass bracket and an anti-corrosion cast iron bracket, and adopts an inner and outer zone optimized arrangement;

[0047] The water spraying filler layer 1 is located on the supporting structure 5 ; the splashing device 3 is located above the water spraying filler layer 2 .

[0048] Optionally, the water-spraying filler layer 1 is divided into an outer circle area, a middle circle area, and an inner circle area, and a filler gradient arrangement is adopted from the outer circle area to the inner circle area, including:

[0049] The height of the water-spraying filler layer 1 decreases from the outer circle area to the inner circle area.

[0050] Optionally, the water spraying filler layer 1 is made of virgin high-efficiency improved S-wave water spraying filler.

[0051] In a possible implementation, the main material of the raw material high-efficiency improved S-wave water-spraying filler is modified polyvinyl chloride plastic sheet, which can be high-efficiency and energy-saving PVC, with PVC content greater than 75%, weight greater than or equal to 22kg / m3, milky white color, and made of raw material.

[0052] In a possible implementation, the water-spraying packing layer 1 is laid out in "unequal height + unequal distance". The core of the unequal height + unequal distance layout optimization technology is to optimize the layout of the packing layer according to the distribution law of the aerodynamic field in the tower. The packing in the outer zone adopts a larger height and a smaller sheet spacing to improve the cooling effect of the peripheral circulating water and make full use of the heat and moisture absorption capacity of the peripheral rising air. The packing in the inner zone adopts a smaller height and a larger sheet spacing to reduce the resistance of the rising air in the inner zone, thereby increasing the air flow rate in the inner zone and enhancing the heat exchange performance of the inner zone.

[0053] According to the distribution characteristics of airflow and water flow in the tower, the water-spraying filler layer is divided into outer circle area, middle circle area and inner circle area from outside to inside, and different types and sheet spacing of fillers are used respectively: the outer area uses the original material JRGX-28 type 28mm sheet spacing high-efficiency improved S-wave water-spraying filler, the middle area uses the JRGX-30 type 30mm sheet spacing filler, and the inner area uses the JRGX-30 type 30mm sheet spacing filler. Through this arrangement, the height and sheet spacing of the filler gradually increase from outside to inside, optimizing the heat exchange effect of the cooling tower.

[0054] Specific as Figure 2 As shown, ③ represents the outer area; ② represents the middle area; ① represents the inner area. According to the distribution law of the aerodynamic field in the tower, this embodiment realizes the coupled optimization of the air flow field, water distribution field and filler distribution in the tower as much as possible, gives full play to the cooling potential of each part of the filler, and the filler height is different at different radii, and its application effect is obvious. The radius difference of the specific filler height is obtained by numerical simulation. The general idea is: in order to make full use of the heat and moisture absorption capacity of the peripheral rising air and further cool the peripheral circulating water, the thickness (height) of the peripheral filler can be increased; compared with the peripheral circulating water temperature, the inner water temperature is higher, but the inner air flow rate is lower, and the heat and moisture absorption capacity of the inner air has been fully utilized. In order to strengthen the inner heat exchange and further cool the inner circulating water, it can be considered to reduce the inner rising air resistance by reducing the thickness of the inner filler, thereby increasing the inner air flow rate and realizing further cooling of the inner circulating water.

[0055] In order to ensure the best spraying effect of the splashing device, the height of the water spraying packing layer is optimized by zoning in this embodiment. The packing layer is divided into an outer circle area (1.5m), a middle circle area (1.25m) and an inner circle area (1.00m) to better match the air flow field in the tower. This optimized layout significantly increases the heat exchange area of ​​the cooling tower, and by improving the coupling of the air-water flow field, further improves the heat exchange efficiency of the cooling tower, while reducing ventilation resistance.

[0056] Through this unequal height + unequal distance layout optimization technology, not only the heat exchange effect of the cooling tower is improved, but also the coordination of air-water flow is enhanced, the ventilation resistance is effectively reduced, and the overall cooling performance is improved.

[0057] like Figure 3 As shown, the support structure 5 includes a dense fiberglass bracket 51 and an anti-corrosion cast iron bracket 52, which are optimally arranged in inner and outer zones, including:

[0058] The support structure 5 of the outer circle area of ​​the water-spraying filler layer 1 adopts an anti-corrosion cast iron bracket 52;

[0059] The supporting structure 5 of the middle and inner circular areas of the water-spraying filler layer 1 adopts a dense fiberglass bracket 51 .

[0060] In one possible implementation, the dense FRP bracket uses a new type of FRP extruded profile. Extruded FRP profiles are made of dense continuous glass fibers wrapped with glass fiber mats. The dense fiber core layer gives the profiles extremely high strength and toughness, and their longitudinal bending strength and impact strength are far superior to ordinary cast iron materials. The use of glass fiber mats enhances the transverse strength of the profiles, while forming a resin-rich layer on the surface, giving them excellent corrosion resistance and anti-fragmentation properties.

[0061] In a possible implementation, the corrosion-resistant cast iron bracket may be a gray cast iron bracket or a ductile iron bracket with a corrosion-resistant coating (such as an epoxy resin coating, a polyurethane coating or other corrosion-resistant coating) coated on the surface, or a high-temperature ceramic coating.

[0062] Optionally, the support structure 5 includes a plurality of support columns 53, which are arranged at intervals along the bottom of the support structure 5, and adjacent support columns 53 are connected by a plurality of cross beams 54, and the bottoms of the support columns 53 are fixedly installed in the water collection tank 6.

[0063] In a possible implementation, the cast iron material is selected from high-strength cast iron that can withstand long-term use, usually gray cast iron or ductile iron, which has good pressure resistance and durability.

[0064] The design of the crossbeam should ensure sufficient bending strength to avoid deformation under strong wind or high load conditions. Usually, the crossbeam can be made of steel or cast iron to ensure a stable connection with the support column and to share the weight of the equipment in the tower. The connection between the crossbeam and the support column is usually fixed by bolts or welding. The specific method used depends on the on-site installation conditions and the strength requirements of the structure. In some cases, a combined connection (such as bolt connection + welding reinforcement) can also be used to ensure stability.

[0065] The bottom of the water collection pool can be designed as a reinforced structure to increase its bearing capacity. Usually, a steel plate or a reinforced base is added at the contact point between the support column and the pool bottom to improve the overall stability. The fixed installation area of ​​the bracket usually uses concrete or reinforced concrete materials as a reinforced foundation to avoid settlement or displacement after long-term stress.

[0066] Optionally, the spraying device 2 adopts an air-water ratio optimization arrangement, including: the distance between the nozzles 21 of the spraying device 2 corresponding to the upper part of the inner circle of the spraying filler layer 1 increases successively from the outer circle area to the upper part of the inner circle area; the diameter of the nozzles 21 of the spraying device 2 corresponding to the upper part of the inner circle of the spraying filler layer 1 decreases successively, such as Figure 4 , Figure 5 , Figure 6 shown.

[0067] In a possible implementation, the nozzle spacing of the corresponding splashing device from the outer circle area to the upper inner circle area of ​​the water spraying filler layer is set according to multiple factors such as the design requirements of the cooling tower, air flow distribution, filler structure, and water flow.

[0068] In a possible implementation, the air velocity in the outer area is relatively high, and the heat absorption capacity of the air flow is relatively strong, so a large water flow rate is required for effective cooling. In order to ensure sufficient cooling effect, the nozzles need to cover a wider range of water. The nozzle spacing in the outer circle area is generally larger, usually set between 0.8m and 1.2m, so that the water flow can cover a larger range and avoid local overheating. The air velocity in the middle circle area is moderate, and the air heat absorption capacity is higher than that in the outer circle area, but the water flow demand is lower than that in the outer circle area. Therefore, it is necessary to appropriately reduce the nozzle spacing to ensure sufficient cooling while avoiding water waste. The nozzle spacing in the middle circle area is generally set to 0.6m to 0.9m, and the water flow rate is moderate, which can meet the cooling needs of the middle area. The air velocity in the inner circle area is relatively high, and the air moisture absorption capacity is strong, so the water flow demand is the smallest. If the water flow rate is too large, it may cause water to evaporate too quickly, resulting in waste. The nozzle spacing in the inner circle area can be set to 0.5m to 0.7m to ensure that the water flow is small and evenly covers the entire area to avoid excessive evaporation of water.

[0069] In one possible implementation, the air flow rate in the outer area is lower, and a larger water flow rate is required for effective cooling. In order to ensure sufficient water flow coverage area, the outer nozzle diameter is relatively large, for example: diameter 25-28mm; the air flow rate in the middle circle area is moderate, and the cooling demand is between the outer circle area and the inner circle area, so the nozzle diameter should be moderate, for example: diameter 22-25mm; the air flow rate in the circular area is higher, and the water flow demand is lower, so the nozzle diameter should be further reduced, for example: diameter 20-22mm.

[0070] Optionally, the spraying device 2 is a self-rotating spraying device;

[0071] The chassis of the self-rotating spray device is driven to rotate by the kinetic energy of water; the bearing of the spray head of the self-rotating spray device has a self-lubricating function;

[0072] The spraying device (2) is provided with a plurality of spray heads (21) connected to a water distribution pipe, and the water distribution pipe is provided with an electric valve (32);

[0073] The length of the corresponding water distribution pipe of the water sprinkling filling layer (1) is staggeredly distributed from the outer circle area to the upper part of the inner circle area; the length of the corresponding water distribution pipe of the water sprinkling filling layer (1) increases successively from the outer circle area to the upper part of the inner circle area.

[0074] In one possible implementation, the splashing device uses a "JRGX-II type layered rotary splashing device", which uses ABS plastic and modified polypropylene (PP) plastic as raw materials, and the spraying particles are finer and the air residence time is longer.

[0075] In one possible implementation, the self-lubricating function of the bearing of the nozzle 21 can be achieved in the following ways: selecting materials with self-lubricating properties (such as alloys or plastics containing lubricating components such as graphite or polytetrafluoroethylene (PTFE)), which can automatically release lubricants during the friction process, reduce friction, and extend the service life of the bearing; pre-installing solid lubricants or grease inside the bearing, these lubricants can be slowly released through friction when the bearing is running, forming a lubricating film, reducing wear and ensuring the lubrication needs during long-term operation.

[0076] In one possible implementation, the water distribution pipe uses UPVC pipes with a specification of ∮160mm-∮355mm. Since the water distribution pipe in the outer circle area is closer to the water source, the length of the water distribution pipe is shorter. The water distribution pipe can be designed as a shorter pipe with a larger diameter to quickly transport water to the outer circle area; the length of the water distribution pipe from the middle circle area to the inner circle area gradually increases to ensure that the water flow can be evenly distributed to the inner circle area. As the length of the water distribution pipe increases, the pressure of the water flow will gradually decrease. Therefore, it is necessary to optimize the design of the water distribution pipe to ensure the stability of the water flow in the middle circle area and the inner circle area.

[0077] Optionally, the cooling tower core component further includes: a performance detection device 3;

[0078] The performance detection device 3 includes a plurality of sensors 31 arranged at the middle and lower part of the water spraying filler layer, a plurality of electric valves 32 arranged on the splashing device, and a control system 33 for controlling the splashing device;

[0079] The sensor 31 is used to detect the performance distribution of the lower part of the water-spraying filler layer 1 and transmit it to the control system 33;

[0080] The control system 33 controls the corresponding spraying devices 2 above different areas of the water spraying filler layer 1 to distinguish the cooling performance of each area of ​​the water spraying filler layer 1.

[0081] The plurality of sensors include a plurality of groups of temperature sensors and wind speed sensors, and the sensors of each group are distributed in different areas of the water spraying filler layer 1 .

[0082] In a possible implementation, the temperature sensor can be installed near the nozzle above the packing layer, in the middle of the packing layer, and at the bottom of the packing layer, which helps to fully obtain temperature change information and monitor the temperature gradient in different areas; the arrangement of the wind speed sensor can consider multi-point detection at different positions such as the top, side, and bottom of the packing layer. In addition, the wind speed sensor should consider the relationship with the nozzle arrangement to monitor the change of wind speed during the splashing process.

[0083] The temperature sensor feeds back the temperature data of different positions to the control system. If there is still no temperature change after spraying adjustment, it can be regarded that the "unequal height + unequal distance" water-spraying filler layer at that location has been damaged and an alarm is issued.

[0084] The wind speed sensor feeds back the wind speed data at different positions to the control system. If the wind speed is high, the control system controls the electric valve on the water distribution pipe, the spraying volume of the outer zone nozzle increases, while the spraying volume of the inner zone nozzle decreases to avoid too fast evaporation of water; if the wind direction changes, the spraying angle of the nozzle can be adjusted in time to form an ideal flow field for water and air flow inside the cooling tower to avoid overcooling or overheating in certain areas due to changes in wind force.

[0085] The beneficial effects of the embodiments of the present application are as follows:

[0086] The present application provides a cooling tower core component, in which a water-spraying filler layer is divided into an outer circle area, a middle circle area and an inner circle area. According to different areas, a gradual arrangement is adopted to meet different airflow and water flow requirements, further optimize the filler heat exchange area, further fully combine air and water, and better match the air flow field in the cooling tower; the splashing device is arranged above the water-spraying filler layer with an air-water ratio optimization, and the nozzle is connected to the water distribution pipe. The nozzle is designed with a self-rotating spraying device, which uses the kinetic energy of water to drive the rotation to ensure that water is evenly sprayed on different areas of the filler layer. The bearing of the nozzle has a self-lubricating function to ensure the stability and durability of long-term operation; the performance detection device is installed on the middle and lower part of the water-spraying filler layer and the water distribution pipe of the splashing device, and a wind speed sensor and a temperature sensor are used to monitor the airflow in the cooling tower in real time. The sensor data is transmitted to the control system, and the control system controls the electric valve to adjust the water flow of the splashing device according to the wind speed data and the temperature data to ensure that the temperature of the inner and outer areas of the water-spraying filler layer is balanced to avoid excessive temperature difference in local areas, which leads to reduced heat exchange efficiency. At the same time, the supporting structure adopts anti-corrosion cast iron brackets and encrypted fiberglass brackets with partition optimization layout. The outer circle area of ​​the water-sprinkling filler layer adopts anti-corrosion cast iron brackets with heavier loads and larger grid spacing, and the middle circle area and inner circle area of ​​the water-sprinkling filler layer adopt encrypted fiberglass brackets with lighter loads and smaller grid spacing, which further optimizes the ventilation resistance, enhances the antifreeze performance, and improves the heat exchange efficiency of the cooling tower. The support columns and beams form a stable structure. The support columns are fixed in the water collection tank to provide additional support and structural stability, ensuring that the overall structure of the cooling tower is not affected by the stress generated during long-term operation, reducing maintenance costs, extending the service life of the cooling tower, and improving the convenience of construction and maintenance. In addition, the length of the water distribution pipe is staggered according to the design of different areas of the cooling tower to ensure uniform water flow distribution in each area and avoid excessive wind resistance or local overheating caused by uneven water flow distribution.
