[0001] The present invention relates to the technical field of fluid pressure execution units, and in particular to a fluid control device used in a spray system. Background Art

[0002] The spray system is an important component of the cooling tower. It accelerates the cooling by spraying at the upper end of the filler. However, it often causes the temperature of the upper section of the filler to be significantly lower than that of the lower section, resulting in insufficient internal temperature uniformity. In addition, the spraying method and the diversion method of the upper diversion mechanism are single and fixed, resulting in limited operating methods 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 causes the temperature of the upper section of the filler to be significantly lower than that of the lower section, resulting in insufficient temperature uniformity, and the spraying method and the diversion method of the upper end guide mechanism are single and fixed, which limits their operating means and has low cooling efficiency.

[0005] The spray filling module is composed of a plurality of curved structural plates arranged in parallel. The inner recess of the curved structural plate is provided with a metal support heat conducting plate connected to the upper and lower sides. A heat exchange flow channel is formed between the metal support heat conducting plate and the inner recessed surface of the curved structural plate.

[0010] An electrically controlled regulating valve is installed inside the centrifugal drive blade at the side spray nozzle communication section.

[0011] The embedded annular guide rail is provided with an overhead adjustment guide rail for controlling the electric-controlled direct drive device, and the interior of the overhead adjustment guide rail is slidably equipped with an overhead slider and a lateral adjustment support rod for installing the electric-controlled direct drive device.

[0012] The outlet directions of the side spray nozzles on both side surfaces of the centrifugal drive blade are opposite.

[0013] Temperature sensing control modules are fixedly installed inside the bottom guide tube and the top guide tube.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0030] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0031] Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7The fluid control device shown is used in a spray system, comprising a spray filling module 2 installed inside a cooling tower body 1, an embedded annular guide rail 3 fixedly mounted on the inner side of the cooling tower body 1 at the upper end of the spray filling module 2, an annular rotating frame 4 movably mounted inside the embedded annular guide rail 3, a centrifugal drive blade 5 fixedly mounted at the center position inside the annular rotating frame 4, side spray nozzles 6 protruding outward are fixed symmetrically and staggered on both sides of the centrifugal drive blade 5, an electrically controlled direct drive device 7 and a hydraulic boosting mechanism 8 for controlling the annular rotating frame 4 are mounted on the embedded annular guide rail 3, and a lateral circulation guide mechanism 9 controlled by the electrically controlled direct drive device 7 is mounted on the spray filling module 2.

[0032] Regulation Principle: High-temperature air is introduced into the cooling tower body 1 through the bottom. The hydraulic booster mechanism 8 then 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 flow inside the cooling tower body 1. While directing the air, the side spray nozzles 6 on the centrifugal drive blades 5 spray directly onto the spray filler module 2 or the inner wall of the cooling tower body 1, further controlling the centrifugal drive blades 5. The spray pattern changes depending on the position of the side spray nozzles 6.

[0033] In order to improve the inner supporting force and enhance internal heat uniformity, the spray filler module 2 is composed of a plurality of curved structural plates 21 arranged in parallel. The inner recess of the curved structural plate 21 has a metal support heat conducting plate 22 connected to the upper and lower sides. A connected heat exchange flow channel is formed between the metal support heat conducting plate 22 and the inner recessed surface of the curved structural plate 21.

[0034] The heat-equalizing liquid inside the heat exchange flow channel can also be heated according to its own temperature difference, with the liquid with a colder temperature flowing downward and the liquid with a hotter temperature flowing upward.

[0035] In order to cooperate with the connection, the lateral circulation guide mechanism 9 includes a bottom guide pipe 91 fixed at the bottom end of one side of the curved structure plate 21, a top guide pipe 92 fixed at the top end of one side of the curved structure plate 21, and a lateral guide mechanism 93 fixed on the inner side of the cooling tower body 1.

[0036] In order to cooperate with the linked flow diversion, the bottom flow diversion pipe 91 and the top flow diversion pipe 92 are both composed of a horizontal flow diversion pipe 94 and an arc-shaped connecting pipe 95 fixed on the side wall of the horizontal flow diversion pipe 94.

[0037] In order to cooperate with the circulation drive, the lateral flow guide mechanism 93 includes a lateral return pipe 931 for connecting the bottom guide pipe 91 and the top guide pipe 92 and a circulation drive pump 932 installed at the bottom end of the lateral return pipe 931.

[0038] The lateral flow guide mechanism 93 is used to fixedly connect the bottom flow guide pipe 91, the top flow guide pipe 92 and the circulation drive pump 932;

[0039] The equalizing liquid in the bottom guide pipe 91 flows into the circulation drive pump 932, and then is guided upward into the interior of the top guide pipe 92 by the circulation drive pump 932. The equalizing liquid then falls downward into the heat exchange flow channel through the top guide pipe 92, absorbs the heat of the metal support heat conducting plate 22, and then flows downward rapidly, thereby achieving the purpose of equalizing heat above and below. The speed of the circulation drive pump 932 is automatically adjusted according to the temperature difference between the bottom guide pipe 91 and the top guide pipe 92.

[0040] The circulation drive pump 932 includes a pump body connected to the bottom guide pipe 91 and the top guide pipe 92, centrifugal pump blades installed inside the pump body, and a synchronous drive shaft for transmitting and connecting the centrifugal pump blades and the electric control direct drive device 7.

[0041] The electric-controlled direct drive device 7 can be driven synchronously with the centrifugal pump blades via a synchronous drive shaft.

[0042] In order to cooperate with the lateral drive, an annular guide groove 41 connected to the side spray nozzle 6 is opened on the outer arc surface of the annular rotating frame 4, and the upper end of the outer arc surface of the annular rotating frame 4 has an annular transmission tooth surface that cooperates with the electric control direct drive device 7.

[0043] The hydraulic boosting mechanism 8 pressurizes the collected liquid at the bottom after purification and filtration, and then draws it upward into the embedded annular guide rail 3, and then introduces it into the annular guide groove 41. The boosted driving liquid inside the annular guide groove 41 is introduced into the side spray nozzle 6 through the centrifugal driving blade 5, and finally sprayed out from the liquid outlet of the side spray nozzle 6. Reverse kinetic energy is generated during the spraying, thereby driving the centrifugal driving blade 5 to move along with the annular rotating frame 4.

[0044] In order to cooperate with the electronically controlled opening and closing, an electronically controlled regulating valve 51 is installed inside the centrifugal drive blade 5 at the communication section of the side spray nozzle 6.

[0045] The electric control valve 51 is opened and closed by electric control, thereby controlling the opening and closing state of the side spray nozzle 6. The electric control valves 51 in the side spray nozzles 6 on the same side are opened and closed synchronously, so that the rotation direction of the centrifugal drive blade 5 can be driven when the spray direction is consistent;

[0046] The spray is directed toward the spray filler module 2. At this time, the reaction force drives the centrifugal drive blades 5 to drive the air to be discharged upward. When the spray is directed toward the cooling tower body 1, the reaction force drives the centrifugal drive blades 5 to blow air downward, reducing the speed of the air being discharged upward, thereby greatly increasing the air residence time, making the air and the spray splashing water mist cooling more sufficient.

[0047] In order to cooperate with the electronically controlled power switching, an overhead adjustment guide rail 31 for controlling the electronically controlled direct drive device 7 is installed on the embedded annular guide rail 3, and an overhead slider 32 and a lateral adjustment support rod 33 for installing the electronically controlled direct drive device 7 are slidingly assembled inside the overhead adjustment guide rail 31.

[0048] The electric-controlled direct-drive device 7 is fixedly mounted on the upper end of the top slider 32 , and the lateral adjustment strut 33 controls the top slider 32 to slide and adjust inside the top adjustment guide rail 31 by telescoping.

[0049] In order to switch the spraying angle, the outlet directions of the side spraying nozzles 6 on both sides of the centrifugal driving blade 5 are opposite.

[0050] In order to monitor the temperature at the upper and lower ends of the spray filling module 2 , temperature sensing control modules 96 are fixedly installed inside the bottom guide pipe 91 and the top guide pipe 92 .

[0051] When the temperature sensing control module 96 can monitor the temperature inside and around the bottom guide tube 91 and the top guide tube 92, when the temperature of the bottom guide tube 91 is much higher than the temperature of the top guide tube 92, the temperature sensing control module 96 can control the lateral adjustment strut 33 to stretch and squeeze 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 driving gear on the lower end driving shaft of the electric control direct drive device 7 is engaged with the synchronous driving 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 flow channel and the heat exchange fluid inside the lateral circulation guide mechanism 9 to circulate rapidly, thereby ensuring the cooling effect of the spray filling module 2.

[0052] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
