[0035] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.
[0036] In the related art, the water distributors configured in the cooling towers of power plants can neither independently adjust the water output of each water distribution nozzle 12 nor adjust the water output of the water distribution nozzle 12 in relation to the air intake. However, the applicant has found that the air intake is an important factor affecting the cooling effect of water vapor.
[0037] In view of this, the embodiment of the utility model provides a power plant cooling tower system that can adjust the water spraying amount according to the air intake volume. The air intake volume of the area corresponding to each water distribution nozzle 12 at the air inlet 14 below the cooling tower cooling filler can be measured, and the water flow rate of each water distribution nozzle 12 can be adjusted by using an independent adjustable water distributor 3, so as to achieve better cooling and energy saving and emission reduction effects. At the same time, the power plant cooling tower system that can adjust the water spraying amount according to the air intake volume of the embodiment of the utility model can also independently control the water output of each water distribution nozzle 12 based on the independent adjustable water distributor 3, so as to achieve the purpose of precise regulation.
[0038] Figures 1 to 8 The structure diagram of a preferred embodiment of the utility model is shown. Figure 1 A power plant cooling tower system capable of adjusting the amount of water sprayed according to the amount of air inlet, comprising:
[0039] A cooling tower 1, wherein a water distribution nozzle 12 and a water spray filler 13 are arranged vertically in a tower barrel 11 of the cooling tower 1, and an air inlet 14 is provided at the bottom of the tower barrel 11 of the cooling tower 1 and below the water spray filler 13;
[0040] A condenser 2, wherein the condenser 2 is connected to the water distribution nozzle 12 through an independently adjustable water distributor 3, and the independently adjustable water distributor 3 can independently adjust the water output of each water distribution nozzle 12, and the condenser 2 is used to spray the condensed water of the steam turbine exhaust onto the water spraying filler 13;
[0041] The air intake volume measuring component 4 is arranged at the air duct section of the air inlet 14 and is configured according to the number of the water distribution nozzles 12. The air intake volume measuring component 4 is used to obtain the air intake volume as the basis for the independent adjustable water distributor 3 to adjust the water output corresponding to the water distribution nozzle 12.
[0042] It should be noted that Figure 1 The structural diagram only shows one water distribution nozzle 12 and one corresponding air inlet volume measurement component 4. It can be understood that in a complete power plant cooling tower system, there are multiple water distribution nozzles 12, which are respectively connected to the water holes 311 of the independent adjustable water distributor 3, and the number of air inlet volume measurement components 4 is also set to correspond to the number and position of the water distribution nozzles 12. Similarly, Figure 3 Only one grid 1411 is drawn in the grid support 141 to introduce the layout details in a single grid 1411 . In fact, the number of grids 1411 is consistent with the number of water distribution nozzles 12 , and the area size of the grid 1411 is determined by the spray range of a single water distribution nozzle 12 .
[0043] In a specific optional implementation of the present utility model embodiment, refer to Figure 1 and Figure 3 A grid bracket 141 is fixedly connected to the air duct section where the air inlet 14 is located. The size of the grids 1411 on the grid bracket 141 is divided according to the corresponding water spray control area of the water distribution nozzle 12.
[0044] In a specific optional implementation of the present utility model embodiment, refer to Figure 2 The air intake measurement component 4 includes a wind measuring cylinder 41 installed in the grid bracket 141, and at least one wind measuring cylinder 41 is installed in each grid 1411 of the grid bracket 141. A speed sensor 42 is penetrated through the side wall of each wind measuring cylinder 41, and the positive and negative pressure side pressure pipes of each speed sensor 42 are connected to a differential pressure transmitter 43, and each pressure transmitter is also connected to an air volume display screen 44.
[0045] In a specific optional implementation of the present utility model embodiment, refer to Figure 3 A plurality of wind measuring cylinders 41 are installed in each grid 1411 of the grid bracket 141, and a speed sensor 42 is arranged through the side wall of each wind measuring cylinder 41. All the speed sensors 42 are connected in series and are connected in sequence to the same differential pressure transmitter 43 and the same air volume display screen 44.
[0046] In a specific optional implementation of the embodiment of the utility model, a plurality of wind measuring wind tubes 41 belonging to the same subgrid 1411 are arranged at multiple points with equal cross-sections in the area of the corresponding subgrid 1411 to improve the accuracy of the measurement.
[0047] Reference Figure 2 and Figure 3 The power plant cooling tower system provided by the embodiment of the utility model divides the air duct cross section at the air inlet 14 into different areas according to the main control area (i.e., the spraying range) of each water distribution nozzle 12 during the water spraying operation. Each area is independently provided with one or a group of air intake volume measuring devices, and then each area is independently connected to a differential pressure transmitter 43 and an air volume display screen 44. The average air volume of each area can be measured conveniently and quickly by using the differential pressure transmitter 43 and the speed sensor 42, so that the air intake volume correlation measurement can be performed for each water distribution nozzle 12 respectively. Finally, the readings of the air intake volume measurement of each area can be viewed in real time through the air volume display screen 44, and the water output of each water permeable hole 311 can be adjusted manually by the independently adjustable water distributor 3 to complete the control of the water spraying volume of the water distribution nozzle 12.
[0048] In a specific optional implementation of the present utility model embodiment, refer to Figure 4-Figure 8The independently adjustable water distributor 3 comprises an outer cylinder 31 with water holes 311 uniformly distributed on the outer circumference, and the water holes 311 are used to connect the water distribution nozzle 12; the outer cylinder 31 is a cylinder structure with openings at both ends, and a central fixing component 32 is coaxially arranged inside the outer cylinder 31, and a plurality of concentrically arranged inner cylinders 33 are stacked between the radial outer side of the central fixing component 32 and the radial inner side of the outer cylinder 31, and the number of the inner cylinders 33 is the same as the number of the water holes; the condenser 2 is connected to the central fixing component 32 and the inner cylinder 33 closest to the outer cylinder 31 through a water distribution pipe; the water holes 311 of the independently adjustable water distributor 3 are connected to the water distribution nozzle 12 through a water distribution pipe.
[0049] Each inner cylinder 33 is provided with a water baffle 333 corresponding to the position of the water permeable hole 311. Each inner cylinder 33 is rotatably connected to the central fixed component 32 through a cantilever flow control component 34. The water baffle 333 is a thin plate with a width greater than the aperture of the water permeable hole and less than the spacing between adjacent water permeable holes. The water baffle 333 can adjust the overlapping area with the water permeable hole 311 within the rotation range.
[0050] When in use, the lower port of the independently adjustable water distributor 3 is used to connect to the condenser 2, and the lower port is specifically the common lower end of the outer cylinder 31 and the inner cylinder 33 corresponding to the second inner cylinder fixing ring. The water vapor of the condenser 2 enters between the fixed central column 321 and the first inner cylinder through the water distribution pipe; then the incoming water passes through the inner cylinders 33 of different forms radially from the inside to the outside to reach the water distribution nozzles 12 in the cooling tower 1, wherein each inner cylinder 33 separately adjusts the water permeable holes 311 on each outer cylinder 31 to realize the independent water output configuration of each water distribution nozzle 12, thus forming different forms of inner cylinders 33 to obtain the best cooling effect of the cooling tower 1.
[0051] Since a plurality of water permeable holes 311 are arranged on the outer cylinder wall of the outer cylinder 31, and the water permeable holes 311 are evenly distributed on the outer cylinder wall in a circular shape, a rotatable inner cylinder 33 is also arranged inside the outer cylinder 31, and the number of the inner cylinder 33 is consistent with the number of the water permeable holes 311, and the water baffle 333 on each inner cylinder corresponds to a water permeable hole 311, so the overlapping area of the water baffle 333 and the water permeable hole 311 is changed by rotating the inner cylinder 33, thereby controlling the water output.
[0052] The rotation of the inner cylinder 33 and the overlap of the water baffle 333 and the water permeable hole 311 in the above process are achieved by means of the structure of the arm control flow assembly, the central fixed assembly 32 and the inner cylinder 33, that is, each inner cylinder 33 is rotatably connected to the central fixed assembly 32 through a cantilever control flow assembly 34 ( Figure 4The assembly drawing of only one cantilever flow control component 34 is shown, and the drawing of other cantilever flow control components 34 is omitted. However, the complete water distributor is provided with a plurality of inner cylinders 33 and the same number of cantilever flow control components 34). The water baffle 333 is a thin plate with a width greater than the aperture of the water permeable hole 311 and less than the spacing between adjacent water permeable holes 311. The water baffle 333 can adjust the overlapping area with the water permeable hole 311 within the rotation range, as follows:
[0053] Each inner cylinder 33 has the same structure and needs to be extremely thin, which can be ignored in engineering. In terms of effect, it can act on the cross section of each water-permeable hole 311 to change its flow without affecting each other. In order to avoid mutual interference, the width of the water-retaining plate 333 should be larger than the aperture of the water-permeable hole 311 and smaller than the distance between adjacent water-permeable holes 311. However, the diameters of all inner cylinders 33 are different. If they are named as the first inner cylinder, the second inner cylinder, the third inner cylinder, etc. in order from small to large inner diameter, then the inner diameter of the first inner cylinder should be equal to the outer diameter of the central fixing assembly 32, the outer diameter of the first inner cylinder is equal to the inner diameter of the second inner cylinder, the outer diameter of the second inner cylinder is equal to the inner diameter of the third inner cylinder, and so on. The outer diameter of the inner cylinder 33 with the largest diameter is equal to the inner diameter of the outer cylinder 31, and they are assembled from the inside to the outside.
[0054] The central fixing component 32 is in a fixed state relative to the outer cylinder 31 and the inner cylinder 33. The specific fixing method is not limited. For example, it can be achieved with the assistance of an external bracket. The central fixing component 32, on the one hand, forms an installation space for the inner cylinder 33 with the outer cylinder 31, and on the other hand, cooperates with the cantilever flow control component 34 to enable each inner cylinder 33 to realize the rotation function.
[0055] In a specific optional implementation of an embodiment of the utility model, the central fixing component 32 includes a fixed central column 321 and a first fixed circular plate 322 and a second fixed circular plate 323 concentrically arranged at both ends of the fixed central column 321, and a plurality of sockets 3221 distributed in a circular array are provided in the middle of the first fixed circular plate 322, and the sockets 3221 are used to dock with one end of the cantilever flow control component 34 to form a rotation center corresponding to the inner cylinder 33; the number of the sockets 3221 is greater than or equal to the number of the inner cylinder 33.
[0056] When the number of sockets 3221 is equal to the number of inner cylinders 33, each cantilever flow control assembly 34 is connected to a socket 3221 and takes the position of the socket 3221 as the rotation center, and the water baffle 333 of the inner cylinder 33 connected to the cantilever flow control assembly 34 only rotates a certain amplitude relative to the rotation center; when the number of sockets 3221 is greater than the number of inner cylinders 33, each socket 3221 position can form a rotation center, which can allow the water baffle 333 of the same inner cylinder 33 to switch to different positions and rotate a certain amplitude, thereby increasing the range of adjustment and obtaining more types of water distribution effects.
[0057] The innermost inner cylinder 33 is sleeved on the outside of the first fixed circular plate 322 and the second fixed circular plate 323, the outermost inner cylinder 33 is sleeved on the inside of the outer cylinder 31, and the other inner cylinders 33 in the middle are tightly sleeved and assembled into one from the inside to the outside.
[0058] In a specific optional implementation of an embodiment of the utility model, each of the inner cylinder bodies 33 includes a first inner cylinder fixing ring 331 and a second inner cylinder fixing ring 332 arranged in parallel, which are aligned and connected through a water retaining plate 333 on the side curved surface, and the first inner cylinder fixing ring 331 and the second inner cylinder fixing ring are used to be sleeved with the first fixed circular plate 322 and the second fixed circular plate 323 of the adjacent central fixed assembly 32, or with the first inner cylinder fixing ring 331 and the second inner cylinder fixing ring 332 of the adjacent inner cylinder body 33.
[0059] In a specific optional implementation of an embodiment of the utility model, the cantilever flow control assembly 34 includes a cantilever plate 341 and a flow control rod 342; one end of the flow control rod 342 is fixedly connected to the end of the cantilever plate 341 close to the socket 3221, and the other end of the flow control rod 342 is rotatably inserted into the socket 3221; the other end of the cantilever plate 341 away from the socket 3221 is fixedly connected to the first fixed circular plate 322.
[0060] In a specific implementation, a threaded hole may be opened on the cantilever plate 341 , and the flow control rod 342 may be set as a screw rod matching the threaded hole, and the flow control rod 342 may be fixedly mounted on the cantilever plate 341 through threaded engagement.
[0061] In a further illustrated implementation manner of this embodiment, the cantilever plate 341 includes a transverse connecting plate 3411 and a longitudinal connecting plate 3412 fixedly connected at one end, and the other ends of the transverse connecting plate 3411 and the longitudinal connecting plate 3412 are fixedly connected to the flow control rod 342 and the inner cylinder respectively.
[0062] Reference Figure 8Taking the first inner cylinder as an example, the assembly relationship between the central fixing component 32, the inner cylinder 33 and the cantilever flow control component 34 in the illustrated embodiment is explained. The first inner cylinder fixing ring 331 is fixedly connected to a cantilever plate 341. The position of the water baffle 333 of the first inner cylinder is changed by rotating the cantilever plate 341, and the flow control rod 342 of the first inner cylinder is rotatably connected to the socket 3221 on the first fixed circular plate 322.
[0063] As another specific alternative to the cantilever plate 341 (not shown), the cantilever plate 341 includes an integrally formed right-angle plate, and the transverse end and the longitudinal end of the right-angle plate are respectively fixedly connected to the flow control rod 342 and the inner cylinder 33. Further, considering that the interference between different cantilever flow control components 34 can be reduced to a minimum, the transverse end and the end of the transverse connecting plate 3411 are preferably designed to be arc-shaped and have a small length beyond the rotation axis.
[0064] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification and equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
