Abstract
Description
Technical Field
[0001] This invention relates to the field of icing removal, and in particular to a device for removing icing from the chimney tip of a power plant in winter. Background Technology
[0002] When power plants emit flue gas, water vapor is often present. At higher temperatures, this water vapor doesn't adhere to the outer wall of the chimney. However, at lower temperatures, it does, and the higher temperature of the outer wall causes the water vapor to condense into water droplets, eventually freezing. This temperature difference between the outer and inner walls can damage the chimney. To eliminate icing on power plant chimneys in winter, electric heat tracing technology is commonly used, connecting the heating cable to the chimney. An optimized approach uses composite material electric heating film anti-icing devices, where the heating film is directly applied to the outer surface of the chimney. This reduces potential failure points such as temperature control elements and cable joints. However, the subsequent maintenance workload for power lines and facilities remains significant, the maintenance process carries considerable safety risks, and the device has a limited lifespan, resulting in relatively high overall costs.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.
[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.
[0032] Example 1
[0033] Reference Figures 1-2 This is the first embodiment of the present invention, which provides a device for eliminating ice formation on the top of a power plant chimney in winter. The device has a constant temperature unit 100, which includes a heat transfer and insulation plate 101, a connecting plate 102, a water pipe 103, a heat insulation sleeve 104, a support plate 105, and a limiting pin 106. The heat transfer and insulation plate 101 and the connecting plate 102 are connected together by the limiting pin 106. The water pipe 103 is laid inside the heat transfer and insulation plate 101, and the heat insulation sleeve 104 is disposed outside the water pipe 103. The support plate 105 is disposed below the heat transfer and insulation plate 101 and the connecting plate 102.
[0034] Specifically, the heat transfer insulation plate 101 and the connecting plate 102 are interlocked. An irregular hole for a limiting pin 106 is reserved at the connection position. To prevent the heat transfer insulation plate 101 and the connecting plate 102 from separating, the limiting pin 106 needs to be inserted. One side of the limiting pin 106 is set as a triangular structure and the other side is set as a rectangular structure, which can be tightly interlocked with the structure at the connection between the heat transfer insulation plate 101 and the connecting plate 102. The water pipe 103 is connected to the connecting plate 102 and is laid inside the heat transfer insulation plate 101 and the connecting plate 102. The heat insulation sleeve 104 wraps the water pipe 103 inside it, ensuring that the heat loss of the water pipe is minimal during transmission. The support plate 105 can support the heat transfer insulation plate 101 and the connecting plate 102 above, making the device more stable.
[0035] In use, the excess heat generated by the power plant during power generation can provide a heat source for the entire device. Therefore, a water pump is needed to transport hot water to the device. The first option is to set two adjacent water pipes 103 as one inlet and one return water pipe, respectively. The remaining three water pipes 103 on the other side have the same inlet and outlet water methods and are located on the same side and in the same position. When hot water enters the water pipe 103, it is transferred to the return water pipe 103 on the other side through the area inside the heat transfer insulation plate 101. Similarly, after the hot water completes the sequential heating of the entire device, it is returned to the heat source for continued heating. This cycle repeats. The exposed water pipes 103 on the outside are protected by the heat insulation sleeve 104, which reduces the heat loss during the transmission process and keeps the temperature of the entire device rising. This prevents the water vapor in contact with the device from freezing after condensation, reducing the occurrence of icing.
[0036] Example 2
[0037] Reference Figures 1 to 11 This is the second embodiment of the present invention, which differs from the first embodiment in that it further includes a condensation unit 200, which includes a condensation inner wall 202 that is engaged with the heat transfer insulation plate 101, a water collection tank 205 disposed below the condensation inner wall 202, a condensation outer wall 201 that is fixedly connected to the water collection tank 205, a condensation pipe 203 that is suspended between the condensation inner wall 202 and the condensation inner wall 201, a retaining ring 204 that is fixedly connected to the condensation pipe 203, and a drain hole 206 opened on the outer edge of the water collection tank 205, wherein the retaining ring 204 engages with the condensation inner wall 202.
[0038] Furthermore, the retaining ring 204 also includes four equally sized and equally spaced fishing holes 204a, the fishing holes 204a being fixedly connected to the retaining ring 204, the condenser tube 203 having a hollow internal structure, and the condenser inner wall 202 also including a limiting ring 202a, the limiting ring 202a being disposed above the condenser inner wall 202.
[0039] Based on the previous embodiment, the condensing unit 200 can collect and discharge the water droplets formed by the condensation of water vapor that was originally attached to the cigarette butt. The inner condensing wall 202 is in direct contact with the heat transfer insulation plate 101 and connecting plate 102 of the constant temperature unit 100, and can effectively absorb the heat from the constant temperature unit 100. There is a gap between the outer condensing wall 201 and the inner condensing wall 202, and both are connected to the water collection tank 205 below. A condensing tube 203 is placed between the outer condensing wall 201 and the inner condensing wall 202. The addition of the condensing tube 203 increases the contact area of water vapor inside the condensing unit 200, allowing it to quickly form water droplets that hang on the condensing tube 203. Then, under the action of gravity, the water droplets fall into the water collection tank 205. The retaining ring 204 is set above the condensing tube 203, suspending the condensing tube 203 inside the condensing unit 200, which can better contact the water vapor and improve the condensation efficiency.
[0040] During installation, the fishing hole 204a on the retaining ring 204 facilitates installation. Installation can be completed simply by using a hoisting tool in conjunction with the fishing hole 204a. The hollow design of the condenser tube 203 effectively reduces weight, resulting in a lower load during installation and operation and ensuring safety. On the other hand, the hollow structure allows for good contact with air and good temperature exchange with the environment, which greatly improves the condensation effect. The limiting ring 202a allows the condenser unit 200 to be placed above the constant temperature unit 100.
[0041] In summary, the condensation unit 200 can collect the water vapor that originally froze on the outer wall of the cigarette butt and form small water droplets that fall into the water collection tank 205 for unified discharge. The condensation unit 200 is in contact with the constant temperature unit 100 and can effectively absorb the heat from the constant temperature unit 100, keeping its internal temperature above 0°C and preventing water droplets from freezing inside. The condensation unit 200 accelerates the condensation process of water vapor, so that the water vapor that originally froze on the outer wall of the cigarette butt quickly turns into water droplets and is collected, reducing the corrosion of the cigarette butt.
[0042] Example 3
[0043] Reference Figures 1 to 11 This is the third embodiment of the present invention, which, based on the first two embodiments, further includes: the water pipe 103 further includes an arc-shaped pipe 103a, which is laid through the heat transfer and insulation plate 101.
[0044] The water pipe 103 is made of aluminum-plastic composite pipe. The aluminum-plastic composite pipe material has good heat conduction and heat transfer, and has good durability and ductility. It can maintain good condition when the pipe is inserted and installed without causing damage. The arc-shaped pipe 103a is set inside the heat transfer insulation plate 101 to adapt to the structure of the heat transfer insulation plate 101, so that it can be better attached to the heat transfer insulation plate 101 without deformation.
[0045] Furthermore, the connecting plate 102 also includes a slot 102a, a mounting hook 102b, and a hook hole 102c. The slot 102a is symmetrically arranged on both sides of the connecting plate 102, the mounting hook 102b is arranged on the inner side of the connecting plate 102, and the hook hole 102c is arranged on the top of the connecting plate 102.
[0046] Preferably, the heat transfer insulation plate 101 further includes inserts 101a, water channels 101b, and positioning holes 101c. The inserts 101a are symmetrically arranged on both sides of the heat transfer insulation plate 101, the water channels 101b penetrate the heat transfer insulation plate 101, and the positioning holes 101c are arranged on both sides of the inserts 101a.
[0047] Specifically, the slot 102a on the connecting plate 102 is designed with a triangular groove on one side, while the insert 101a of the heat transfer insulation plate 101 is designed with a rectangular groove on one side. When the heat transfer insulation plate 101 and the connecting plate 102 are connected together, the different grooves on the two form a groove structure with a triangle on top and a rectangle on the bottom. At this time, the limiting pin 106 needs to be inserted into it for locking and fixing. When you want to disconnect the heat transfer insulation plate 101 and the connecting plate 102, they will be locked with the triangular and rectangular structures of the limiting pin 106 respectively, thus maintaining the stability of the device. When the heat transfer insulation plate 101 and the connecting plate 102 are connected, the two parts can be inserted in the axial direction or in the vertical direction. The connecting plate 102 is also provided with an installation hook 102b. The installation hook 102b can be locked on the top of the smoke head. When the entire device is installed above the smoke head, the hook structure is installed into the hook hole 102c to facilitate the lifting of the device for installation.
[0048] Preferably, the connecting plate 102 further includes a small water pipe hole 102d and a main water pipe hole 102e. The small water pipe holes 102d are arranged on both sides of the connector 102, and the main water pipe hole 102e is symmetrically arranged on both sides inside the connector 102 and communicates with the small water pipe holes 102d.
[0049] Preferably, the limiting pin 106 further includes a tightening bolt 106a, a limiting post 106b, and a pressure plate 106c. The tightening bolt 106a is disposed above the limiting post 106b, and the lower part of the tightening bolt 106a extends into the limiting pin 106 and is threadedly engaged. The pressure plate 106c is symmetrically disposed on both sides below the limiting pin 106.
[0050] Preferably, the limiting pin 106 further includes a telescopic head 106b-1, a spring 106b-2, and a groove 106b-3 disposed therein. The telescopic head 106b-1 is disposed below the limiting post 106b and cooperates with the groove 106b-3 at the end of the limiting post 106b. The spring 106b-2 is disposed below the telescopic head 106b-1, and its lower end is fixedly connected to the inner wall of the limiting pin 106.
[0051] During use, a water channel hole 101b is provided on the heat transfer insulation plate 101. The water channel hole 101b facilitates the insertion and installation of the arc-shaped tube 103a. The positioning hole 101c can cooperate with the limiting pin 106. After inserting the limiting pin 106, the tightening bolt 106a located at its top is tightened. The tightening bolt 106a is engaged with the internal thread of the limiting pin 106. Below the tightening bolt 106a, there are two limiting posts 106b. The lower end of the limiting post 106b is provided with an inclined groove 106b-3 structure. Below the limiting post 106b, there is also a telescopic structure, which consists of a telescopic head 106b-1 and a spring 10. Composed of 6b-2, when the tightening bolt 106a is tightened downwards, it contacts the limiting post 106b, causing the limiting post 106b to move along the axial direction. The middle part of the two limiting posts 106b is spread apart by the tightening bolt. During the movement, the longer side of the groove 106b-3 squeezes the telescopic head 106b-1. As the telescopic head 106b-1 moves downwards, it compresses the spring 106b-2. When the tightening bolt 106a is loosened, the spring 106b-2 rebounds, which can drive the telescopic head 106b-1 to move upwards. At this time, squeezing the groove 106b-3 will cause the limiting post 106b to move inwards.
[0052] The small water pipe hole 102d on the connecting plate 102 is to ensure that the water pipe passes through smoothly, while the main water pipe hole 102e is fixedly connected to the water inlet pipe 103 and completes the water diversion operation inside. The pressure plate 106c above the limiting pin 106 can effectively stick the connecting plate 102 and the heat transfer insulation plate 101 together to prevent them from moving and causing damage.
[0053] In use, Embodiment 1 provides a water supply method and a water return method. There is another solution to achieve the constant temperature function, namely, to adopt a different solution for the water inlet and return method. The two sides are set with the same water path. For example, the water path at the opposite position is the hot water inlet pipe 103 and the cold water return pipe 103. In this way, during the heating process, it can be ensured that the water in the water pipe on the same side is either hot water or cold water, and it can also play a good role in heat preservation of the constant temperature unit 100.
[0054] In summary, when the flue gas emits large amounts of water-rich gases in winter, this system firstly prevents water vapor from directly contacting the outer wall of the flue gas, reducing the formation of water droplets and thus decreasing icing. Secondly, condensation recovery rapidly condenses the water vapor that would otherwise adhere to the outer wall of the flue gas, preventing its accumulation and further reducing icing. The collected water vapor quickly forms droplets and is discharged, reducing its storage time inside the device and extending its lifespan. Furthermore, water vapor recovery reduces the direct emission of pollutants from power plant combustion into the air, mitigating environmental pollution to some extent. Finally, regarding heat utilization, excess heat generated during power plant generation can be recovered, reducing energy consumption.
