[0002] The spray system is one of the important components of the cooling tower. By spraying water at the upper end of the packing, its cooling is accelerated. However, this often leads to a significantly lower temperature in the upper section of the packing than in the lower section, insufficient internal temperature uniformity, and the spraying method and the guiding method of the upper-end guiding mechanism are single and fixed, resulting in limited operation means and low efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the traditional cooling method often leads to a significantly lower temperature in the upper section of the packing than in the lower section, resulting in insufficient temperature uniformity, and the spraying method and the guiding method of the upper-end guiding mechanism are single and fixed, resulting in limited operation means and low cooling efficiency.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a fluid pressure control device applied to a spray system, including a spray packing module installed inside the cooling tower body. An embedded annular guide rail is fixedly assembled at the upper end of the inner side surface of the cooling tower body. An annular rotating frame is movably assembled inside the embedded annular guide rail. A centrifugal driving blade is fixedly assembled at the central position inside the annular rotating frame. Side spray nozzles protruding outward are symmetrically and staggeredly fixed on both side surfaces of the centrifugal driving blade. An electric control direct drive device and a hydraulic pressure boosting mechanism for controlling the annular rotating frame are installed on the embedded annular guide rail. A lateral circulation guiding mechanism controlled by the electric control direct drive device is installed on the spray packing module.

[0005] The spray packing module is composed of a plurality of juxtaposed curved structural plates. Metal support heat conducting plates with upper and lower lateral connections are provided in the inner concave portions of the curved structural plates. A heat exchange flow channel communicating with each other is formed between the metal support heat conducting plates and the inner concave surfaces of the curved structural plates.

[0006] The lateral circulation guiding mechanism includes a bottom guiding pipe fixed at the bottom end of one side of the curved structural plate, a top guiding pipe fixed at the top end of one side of the curved structural plate, and a side guiding mechanism fixed on the inner side surface of the cooling tower body.

[0007] Both the bottom guiding pipe and the top guiding pipe are composed of a horizontal guiding pipe and an arc-shaped connecting pipe fixed on the side wall of the horizontal guiding pipe.

[0008] The side guiding mechanism includes a lateral return pipe for connecting the bottom guiding pipe and the top guiding pipe, and a circulation driving pump installed at the bottom end of the lateral return pipe.

[0009] An annular guide groove communicating with the side spray nozzles is formed on the outer arc surface of the annular rotating frame, and an annular transmission tooth surface cooperating with the electric direct drive device is provided at the upper end of the outer arc surface of the annular rotating frame.

[0010] An electric control regulating valve is installed inside the centrifugal drive blade at the communicating section of the side spray nozzles.

[0011] A top adjustment guide rail for controlling the electric direct drive device is installed on the embedded annular guide rail, and a top slider and a lateral adjustment support rod for installing the electric direct drive device are slidably assembled inside the top adjustment guide rail.

[0012] The outflow ports of the side spray nozzles on both sides of the centrifugal drive blade are in opposite directions.

[0013] Temperature sensing control modules are fixedly assembled inside both the bottom guide pipe and the top guide pipe.

[0014] The beneficial effects of the present invention are as follows: (1) The fluid pressure control device applied to the spray system of the present invention drives the annular rotating frame with centrifugal drive blades installed inside by adopting various methods such as hydraulic active and direct drive, so that the driving methods are diverse, can be freely changed according to the cooling requirements, and the operability is greatly enhanced; (2) The electric direct drive device of the embedded annular guide rail can be electrically controlled according to the control requirements, so as to switch and control the annular rotating frame and the lateral circulation guide mechanism, making the control method more diverse and the operation more convenient; (3) Side spray nozzles protruding outward are symmetrically and staggeredly fixed on both sides of the centrifugal drive blade. While driving the annular rotating frame to rotate by the hydraulic pressure boosting mechanism on the embedded annular guide rail, liquid is supplied to the side spray nozzles, so as to spray cooling water towards the cooling tower body or the spray packing module, making the spraying method more diverse; (4) The spray and guide mechanisms are combined into one, reducing the internal structure of the cooling tower, thereby improving the utilization rate of the internal space; (5) The lateral circulation guide mechanism can not only supply liquid to the side spray nozzles, but also drive the drive blades on the inner wall of the annular guide groove, greatly improving the kinetic energy utilization rate; (6) The kinetic energy of the fluid can be converted into the mechanical energy of the centrifugal drive blade, and then the internal air is controlled to flow upward, making the kinetic energy conversion more convenient.

[0023] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0024] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 A fluid pressure control device applied to a spray system as shown in, includes a spray packing module 2 installed inside a cooling tower body 1. An embedded annular guide rail 3 is fixedly assembled at the upper end of the inner side surface of the cooling tower body 1. An annular rotating frame 4 is movably assembled inside the embedded annular guide rail 3. A centrifugal drive blade 5 is fixedly assembled at the central position inside the annular rotating frame 4. Side-mounted spray nozzles 6 protruding outward are symmetrically and staggeredly fixed on both side surfaces of the centrifugal drive blade 5. An electric control direct drive device 7 and a hydraulic pressure boosting mechanism 8 for controlling the annular rotating frame 4 are installed on the embedded annular guide rail 3. A lateral circulation diversion mechanism 9 controlled by the electric control direct drive device 7 is installed on the spray packing module 2.

[0026] Adjustment principle: High-temperature air is introduced into the cooling tower body 1 from the bottom, and then the hydraulic boosting mechanism 8 drives the annular rotating frame 4 to rotate along the embedded annular guide rail 3, driving the centrifugal drive blades 5 to control the air diversion inside the cooling tower body 1. While diverting the air, the side spray nozzles 6 on the centrifugal drive blades 5 directly spray water onto the spray packing module 2 or the inner wall of the cooling tower body 1 to further control the centrifugal drive blades 5. By opening and closing the side spray nozzles 6 at different positions, the spraying method is changed.

[0027] To enhance the inner support force and strengthen the internal heat uniformity, the spray packing module 2 is composed of a plurality of curved structural plates 21 arranged side by side. The inner concave part of the curved structural plate 21 has metal support heat-conducting plates 22 that communicate laterally up and down. A heat exchange flow channel that communicates with each other is formed between the metal support heat-conducting plate 22 and the inner concave surface of the curved structural plate 21.

[0028] The heat-equalizing liquid inside the heat exchange flow channel can also equalize heat according to its own temperature difference. The liquid at a relatively lower temperature flows downward, and the liquid at a relatively higher temperature flows upward.

[0029] To cooperate with the connection, the lateral circulation diversion mechanism 9 includes a bottom diversion pipe 91 fixed to the bottom end of one side of the curved structural plate 21, a top diversion pipe 92 fixed to the top end of one side of the curved structural plate 21, and a side diversion mechanism 93 fixed to the inner side surface of the cooling tower body 1.

[0030] To cooperate with the linkage diversion, both the bottom diversion pipe 91 and the top diversion pipe 92 are composed of a horizontal diversion pipe 94 and an arc-shaped connecting pipe 95 fixed to the side wall of the horizontal diversion pipe 94.

[0031] To cooperate with the circulation drive, the side diversion mechanism 93 includes a lateral return pipe 931 for connecting the bottom diversion pipe 91 and the top diversion pipe 92 and a circulation drive pump 932 installed at the bottom end of the lateral return pipe 931.

[0032] The side diversion mechanism 93 is used to fixedly connect the bottom diversion pipe 91, the top diversion pipe 92, and the circulation drive pump 932; The heat-equalizing liquid in the bottom diversion pipe 91 flows into the circulation drive pump 932, and then the circulation drive pump 932 upwardly introduces the heat-equalizing liquid into the top diversion pipe 92. Then, it falls downward through the top diversion pipe 92 into the heat exchange flow channel, absorbs the heat of the metal support heat-conducting plate 22 and then quickly flows downward, so as to achieve the purpose of upper and lower heat equalization. The rotation speed of the circulation drive pump 932 is automatically adjusted according to the temperature difference inside the bottom diversion pipe 91 and the top diversion pipe 92.

[0033] The circulating drive pump 932 includes a pump body communicating with the bottom guide pipe 91 and the top guide pipe 92, a centrifugal pump impeller installed inside the pump body, and a synchronous drive shaft for drivingly connecting the centrifugal pump impeller and the electric direct drive device 7.

[0034] The electric direct drive device 7 can be synchronously driven with the centrifugal pump impeller through the synchronous drive shaft.

[0035] To cooperate with the lateral drive, an annular diversion groove 41 communicating with the side spray nozzles 6 is provided on the outer arc surface of the annular rotating frame 4, and an annular driving tooth surface cooperating with the electric direct drive device 7 is provided at the upper end of the outer arc surface of the annular rotating frame 4.

[0036] The hydraulic boosting mechanism 8 boosts and pumps the collected liquid at the bottom upward into the embedded annular guide rail 3 after purification and filtration, and then introduces it into the annular diversion groove 41. The boosted driving liquid located inside the annular diversion groove 41 is introduced into the side spray nozzles 6 through the centrifugal driving blades 5, and finally sprays out from the liquid outlet of the side spray nozzles 6. At the same time of spraying, a reverse kinetic energy will be formed, thereby driving the centrifugal driving blades 5 to move along with the annular rotating frame 4.

[0037] To cooperate with the electric control for opening and closing, an electric control valve 51 is installed inside the centrifugal driving blade 5 at the connection section communicating with the side spray nozzles 6.

[0038] The electric control valve 51 is opened and closed by electric control, thereby controlling the opening and closing state of the side spray nozzles 6. The electric control valves 51 in the side spray nozzles 6 on the same side are opened and closed synchronously, so as to ensure that when the spraying directions are the same, the rotation direction of the centrifugal driving blades 5 can be driven; When the spraying is directed towards the spray packing module 2, at this time, the centrifugal driving blades 5 are driven by the reaction force to drive the air to be discharged upward. When the spraying is directed towards the cooling tower body 1, the reaction force drives the centrifugal driving blades 5 to blow downward, reducing the upward discharge speed of the air, thereby greatly increasing the air residence time and making the cooling of the air and the sprayed sputtering water mist more sufficient.

[0039] To cooperate with the electric control for power switching, a top adjustment guide rail 31 for controlling the electric direct drive device 7 is installed on the embedded annular guide rail 3. A top slider 32 for installing the electric direct drive device 7 and a lateral adjustment support rod 33 are slidably assembled inside the top adjustment guide rail 31.

[0040] The electric direct drive device 7 is fixedly installed at the upper end of the top slider 32, and the lateral adjustment support rod 33 controls the sliding adjustment of the top slider 32 inside the top adjustment guide rail 31 by telescoping.

[0041] To switch the spraying angle, the outflow port directions of the side spray nozzles 6 on both sides of the centrifugal driving blades 5 are opposite.

[0042] In order to monitor the temperatures at the upper and lower ends of the spray packing module 2, temperature sensing and control modules 96 are fixedly assembled inside both the bottom guide pipe 91 and the top guide pipe 92.

[0043] When the temperature sensing and control module 96 can monitor the temperatures inside and around the bottom guide pipe 91 and the top guide pipe 92, and when the temperature of the bottom guide pipe 91 is much higher than that of the top guide pipe 92, the temperature sensing and control module 96 can control the lateral adjusting strut 33 to extend and press the top slider 32, and then drive the electric control direct drive device 7 to move outward through the top slider 32, so that the drive gear on the lower drive shaft of the electric control direct drive device 7 meshes with the synchronous drive shaft of the circulation drive pump 932. At this time, the electric control direct drive device 7 will be separated from the annular transmission tooth surface on the outer arc surface of the annular rotating frame 4, and the electric control direct drive device 7 directly drives the heat exchange liquid inside the heat exchange flow channel and the lateral circulation guide mechanism 9 to circulate rapidly, thereby ensuring the cooling effect of the spray packing module 2.

The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
