Description

Technical Field

[0001] This utility model relates to the field of power plant cooling technology, specifically to a device for improving the efficiency of power plant cooling systems. Background Technology

[0002] In the power plant production system, the cooling system is a core auxiliary unit that ensures the safe and stable operation of the unit. Its core function is to remove the heat generated by key equipment such as turbine exhaust, generator stator, and boiler auxiliary equipment through medium circulation (such as circulating water and cooling oil), and maintain the equipment within a safe temperature rise range of ≤65K, which directly affects the power plant's power generation efficiency and unit life.

[0003] Currently, during the operation of power plant cooling systems, scale (such as calcium carbonate and calcium sulfate deposits) easily forms on the walls of heat exchangers. As the scale on the tube walls thickens, the heat exchange efficiency gradually decreases, requiring periodic shutdowns for acid cleaning and descaling. This not only affects the continuous operation of the unit but also corrodes the tube walls, shortening the equipment's lifespan, and increases energy consumption and maintenance costs. In view of this, a device for improving the efficiency of power plant cooling systems is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a device for improving the efficiency of power plant cooling systems, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes a power plant cooling system efficiency improvement device, comprising a mounting frame on which a condenser is mounted. The condenser is connected to an inlet pipe and to a fixed tank via a connecting pipe. An outlet pipe is connected to the fixed tank. A neutralization component and a cleaning component are installed in the fixed tank. A drain outlet is provided at the bottom of the fixed tank. A filter screen is fixedly installed in the outlet pipe. The neutralization component includes: A hollow shaft, wherein a limit ring is fixedly connected to the outer wall of the hollow shaft; An acid inlet is rotatably connected to the top of a hollow shaft, and a bracket is fixedly connected to the outer wall of the acid inlet. And a first gear, which is penetrated by a hollow shaft and fixedly connected to the hollow shaft, and a second gear meshes with the first gear, which is fixedly connected to the output shaft of the motor.

[0006] Preferably, a stirring rod is fixedly connected to the outer wall of the hollow shaft, and the stirring rod has a through-hole.

[0007] Preferably, a sliding sleeve is slidably connected to the inner wall of the stirring rod, and the sliding sleeve is elastically connected to the inner wall of the stirring rod by a return spring. A through groove is provided on the outer wall of the sliding sleeve, and a limit block is fixedly connected to the inner wall of the stirring rod.

[0008] Preferably, the top of the fixed tank is detachably connected to a cover plate, and the motor is fixedly connected to the cover plate.

[0009] Preferably, the hollow shaft passes through the cover plate and is rotatably connected to the cover plate, and the limiting ring is rotatably connected to the cover plate.

[0010] Preferably, the cleaning assembly includes a rotating disk rotatably connected to the lower side of the cover plate, a ratchet fixedly connected to the inner wall of the rotating disk, the ratchet engaging with an elastic telescopic rod, an elastic telescopic arm fixedly connected to the outer wall of the rotating disk, and a cleaning brush fixedly connected to the telescopic end of the elastic telescopic arm.

[0011] Preferably, the elastic telescopic rod is fixedly connected to the outer wall of the hollow shaft.

[0012] This utility model provides an efficiency improvement device for power plant cooling systems. It has the following beneficial effects: (1) The power plant cooling system efficiency improvement equipment uses a neutralization component. The motor drives gear two to rotate gear one, which makes the hollow shaft rotate synchronously. The acid is injected into the hollow shaft through the acid addition port. As the hollow shaft rotates, it is evenly diffused into the fixed tank through the port on the stirring rod. It reacts with the calcium ions in the cooling medium to prevent the deposition of calcium carbonate and calcium sulfate. This reduces the impurities attached to the condenser tube wall during the subsequent circulation of the cooling medium and improves the heat exchange effect.

[0013] (2) The power plant cooling system efficiency improvement equipment uses a sliding sleeve and a return spring to make the sliding sleeve squeeze when acid is added, so that the sliding sleeve contacts the limit block, and the opening and the channel are aligned so that the acid can flow out normally. When no acid is added, the sliding sleeve blocks the opening under the action of the return spring during the stirring process to prevent the cooling medium from entering the stirring rod.

[0014] (3) The power plant cooling system efficiency improvement equipment uses a cleaning component. When the filter screen needs to be cleaned, the hollow shaft rotates counterclockwise, causing the elastic telescopic rod to drive the rotating disk to rotate, which in turn drives the cleaning brush to clean the filter screen, reducing impurities from flowing into the subsequent cooling mechanism, further improving the heat exchange effect. When there are many impurities, they can be discharged through the outlet at the bottom of the fixed tank. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-6This utility model proposes an efficiency improvement device for a power plant cooling system, including a mounting frame 1, on which a condenser 3 is installed. The condenser 3 is connected to an inlet pipe 2 and a fixed tank 4 is connected to a connecting pipe. The fixed tank 4 is connected to an outlet pipe 5. A neutralization component 6 and a cleaning component 7 are installed in the fixed tank 4. A drain outlet is opened at the bottom of the fixed tank 4. A filter screen 8 is fixedly installed in the outlet pipe 5. The high-temperature cooling medium enters the condenser 3 through the inlet pipe 2, and after completing heat exchange and cooling, it flows into the fixed tank 4 through the connecting pipe. The pH of the cooling medium is adjusted by the component 6. The treated medium flows back to the cooling system through the outlet pipe 5. The filter screen 8 intercepts residual particles.

[0021] In this embodiment of the invention, the neutralization component 6 includes a hollow shaft 61, an acid inlet 63, and a gear 65. A limiting ring 62 is fixedly connected to the outer wall of the hollow shaft 61. The acid inlet 63 is rotatably connected to the top of the hollow shaft 61. A bracket 64 is fixedly connected to the outer wall of the acid inlet 63. The gear 65 is penetrated by the hollow shaft 61 and fixedly connected to it. The gear 65 meshes with a gear 66, which is fixedly connected to the output shaft of the motor 67. A cover plate 41 is detachably connected to the top of the fixed tank 4. The motor 67 is fixedly connected to the cover plate 41. The hollow shaft 61 penetrates the cover plate 41 and rotates with it. The locating ring 62 is rotatably connected to the cover plate 41. A stirring rod 611 is fixedly connected to the outer wall of the hollow shaft 61. The stirring rod 611 has a through-hole 612. During neutralization, the motor 67 drives the gear 66 to rotate. Through gear meshing, the gear 65 and the hollow shaft 61 rotate. The acid solution is injected into the hollow shaft 61 through the acid addition port 63. As the hollow shaft 61 rotates, it diffuses evenly into the fixed tank 4 through the through-hole 612 on the stirring rod 611. It reacts with the calcium ions in the cooling medium, preventing the deposition of calcium carbonate and calcium sulfate. This reduces the impurities adhering to the condenser tube wall during the subsequent circulation of the cooling medium, thus improving the heat exchange effect.

[0022] Furthermore, a sliding sleeve 613 is slidably connected to the inner wall of the stirring rod 611. The sliding sleeve 613 is elastically connected to the inner wall of the stirring rod 611 through a return spring. A through groove 614 is provided on the outer wall of the sliding sleeve 613. A limit block 615 is fixedly connected to the inner wall of the stirring rod 611. When acid is added, it will squeeze the sliding sleeve 613, causing the sliding sleeve 613 to contact the limit block 615. Then, the through port 612 is aligned with the through groove 614, and the acid can flow out normally. When no acid is added, during the stirring process of the stirring rod 611, the sliding sleeve 613 blocks the through port 612 under the action of the return spring to prevent the cooling medium from entering the stirring rod 611.

[0023] Furthermore, the cleaning component 7 includes a rotating disk 71, which is rotatably connected to the lower side of the cover plate 41. A ratchet is fixedly connected to the inner wall of the rotating disk 71, and the ratchet engages with the elastic telescopic rod 72. An elastic telescopic arm 73 is fixedly connected to the outer wall of the rotating disk 71, and a cleaning brush 74 is fixedly connected to the telescopic end of the elastic telescopic arm 73. The elastic telescopic rod 72 is fixedly connected to the outer wall of the hollow shaft 61. Driven by the motor 67, the hollow shaft 61 rotates counterclockwise, causing the elastic telescopic arm 73 to drive the rotating disk 71 to rotate, thereby driving the cleaning brush 74 to clean the filter screen 8, reducing the flow of impurities into the subsequent cooling mechanism, further improving the heat exchange effect, and when there are many impurities, they can be discharged through the outlet at the bottom of the fixed tank 4.

[0024] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install, and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here. The standard parts used in this application can all be purchased from the market. The specific connection methods of each part are all connected by conventional means such as riveting and welding that are mature in the prior art. The standard parts are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art.

[0025] In use, the high-temperature cooling medium enters the condenser 3 through the inlet pipe 2. After heat exchange and cooling, it flows into the fixed tank 4 through the connecting pipe. The motor 67 is started, driving gear 2 66 to rotate. Through gear meshing, gear 1 65 and the hollow shaft 61 rotate. The acid solution is injected into the hollow shaft 61 through the acid addition port 63. As the hollow shaft 61 rotates, it diffuses evenly into the fixed tank 4 through the port 612 on the stirring rod 611, reacting with calcium ions in the cooling medium to prevent the deposition of calcium carbonate and calcium sulfate. During the process, the sliding sleeve 613 is squeezed, causing it to contact the limiting block 615, thereby aligning the through-hole 612 with the through-groove 614, allowing the acid to flow out normally. When no acid is added, the sliding sleeve 613 blocks the through-hole 612 under the action of the return spring during the stirring process of the stirring rod 611. When it is necessary to clean the filter screen 8, the hollow shaft 61 is driven by the motor 67 to rotate counterclockwise, which drives the cleaning brush 74 to clean the filter screen 8 and reduce the adhesion of impurities on the filter screen 8.

[0026] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
