Description

Technical Field

[0001] This utility model relates to the field of intercooling tower technology, and in particular to an intercooling tower fin cleaning device. Background Technology

[0002] An indirect cooling tower is a device used to cool the exhaust steam from a steam turbine in a thermal power unit. This device consists of heat exchangers and a hyperbolic tower body. The heat exchangers are spatially shaped as three-dimensional triangular prisms, with a horizontal cross-section forming an isosceles triangle (referred to as the cooling triangle). Multiple heat exchangers are vertically arranged and circumferentially positioned below the hyperbolic tower body along the indirect cooling tower. Specifically, as... Figure 4 As shown, the heat exchanger 5 mainly consists of a heat exchange box 51, louvers 53, and heat exchange fins 52.

[0003] The heat exchange box 51 consists of two isosceles triangles with two isosceles sides. Heat exchange fins 52 are mounted on the heat exchange box 51 to increase the heat exchange area. A louver 53 is attached to both ends of the two heat exchange boxes 51, forming the base of the isosceles triangles. The two heat exchange boxes 51 and the louver 53 together constitute the cooling triangle of the indirect cooling tower.

[0004] When air from a low-temperature environment passes through the hyperbolic tower and flows from the bottom to the top, the air cools the turbine circulating water through heat exchanger 5, thereby reducing the temperature of the turbine circulating water.

[0005] Due to frequent strong winds and sandstorms in some areas, the heat exchange fins 52 of the cooling triangle are easily contaminated by dust, causing blockages, affecting the cooling effect, and in severe cases, affecting the safe operation of the unit.

[0006] The existing solution is to use simple lifting equipment to lift workers to a high altitude to perform cleaning operations. Although this method basically solves the problem of cleaning the triangular heat exchange fins 52 of the indirect cooling tower, the cleaning method is extremely inefficient. The cleaning personnel are suspended in the air and have to operate high-pressure water guns to clean the surface point by point and row by row. This not only involves a large workload and low cleaning efficiency, but also poses a significant safety hazard. Utility Model Content

[0022] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0023] Given that the current technology for manually cleaning heat exchange fins is not only labor-intensive and inefficient, but also poses significant safety hazards.

[0024] like Figures 1-5As shown, this embodiment of the invention provides a device for cleaning the fins of an intercooler tower, used to clean the heat exchange fins 52 of the intercooler tower. Figure 1 As shown, the fin cleaning device for the intercooling tower includes several parts such as: base 1, high-pressure nozzle 2, support roller 3, and telescopic support column 4.

[0025] The base 1 is shaped like an isosceles triangular frame and is located inside the heat exchanger 5, that is, inside the cooling triangle. The two isosceles sides of the base 1 correspond parallel to the two heat exchange boxes 51. The bottom edge of the base 1 corresponds parallel to the louvers 53.

[0026] Multiple high-pressure nozzles 2 are evenly spaced on each isosceles side of the base 1. Each high-pressure nozzle 2 faces the corresponding heat exchange fin 52. The high-pressure water sprayed from the nozzle 2 is in a divergent state and can cover the corresponding heat exchange fin 52, forming a water curtain that covers the entire heat exchange fin 52 being cleaned. The distance between each high-pressure nozzle 2 and the corresponding heat exchange fin 52 is equal, so that the water pressure sprayed from each nozzle 2 onto the heat exchange fin 52 is equal, effectively breaking down the scale layer on the heat exchange fin 52 without damaging it.

[0027] The support roller 3 is located at the periphery of the base 1 at the triangular area. The support roller 3 can slide along the three inner angles of the cooling triangle. In other words, the base 1 can slide smoothly within the cooling triangle through the support roller 3.

[0028] The telescopic support 4 is mounted on the base 1, and the base 1 can extend or retract along the interior of the cooling triangle via the telescopic support 4. When the heat exchanger 5 is placed vertically, the end of the telescopic support 4 away from the base 1 is in contact with the bottom of the hyperbolic tower body.

[0029] Specifically, the base 1 has multiple high-pressure delivery branch pipes (not shown in the figure) corresponding to multiple high-pressure nozzles 2. The multiple high-pressure delivery branch pipes are connected to a high-pressure delivery main pipe (not shown in the figure) located outside the base 1. The high-pressure delivery main pipe is equipped with a control valve (not shown in the figure). The high-pressure delivery main pipe is connected to an external water system (not shown in the figure). Water from the external water system is delivered to the high-pressure nozzles 2 through the high-pressure delivery main pipe and the high-pressure delivery branch pipes. The heat exchange fins 52 are cleaned by the high-pressure nozzles 2.

[0030] The telescopic support column 4 includes at least two columns 41 whose external dimensions decrease sequentially along the telescopic direction (i.e., along the base 1) and are coaxially slidably arranged. The shape (cross-sectional shape) of each column 41 can be the same, such as square, round, or elliptical columns, or they can be different. For example, a round column 41 and a square column 41 can be slidably arranged with each other. They can be matched and slid by slotting or other feasible structures on the sides of the two columns that slide against each other.

[0031] The telescopic support 4 also includes a telescopic drive mechanism 42 and a transmission mechanism 43.

[0032] Each pair of adjacent columns 41 is connected by a transmission mechanism 43. A transmission mechanism 43 is provided between the opposite side walls of each pair of adjacent columns 41. That is, each pair of adjacent columns 41 is connected by at least two sets of transmission mechanisms 43 arranged opposite each other. For example, three or four sets of transmission mechanisms 43 can be provided between each pair of adjacent columns 41 to ensure the transmission stability and smooth operation of the telescopic movement between the adjacent columns 41. Preferably, in this embodiment, there are two sets of transmission mechanisms 43 arranged opposite each other. More specifically, the transmission mechanism 43 in this embodiment consists of a slider and a groove. Each pair of adjacent columns 41 has a slide rail on one column 41 and a groove on the adjacent column 41. The slide rail on one column 41 is placed in the groove of the other column 41, and one column 41 slides along the groove of the other column 41 in a predetermined direction.

[0033] For ease of drive control, the telescopic drive mechanism 42 can be a telescopic cylinder or an electric telescopic rod.

[0034] The telescopic drive mechanism 42 is located in the first column 41 (e.g., the lowest column 41 in a vertically lifting telescopic structure) along the extension direction of the telescopic support 4 (along the direction of the base 1), and the output end of the telescopic drive mechanism 42 is fixedly connected to the last column 41 (i.e., the last column 41 in the extension direction, e.g., the highest column 41 in a vertically lifting structure) along the extension direction of the telescopic support 4. The telescopic drive mechanism 42 is activated to drive the last column 41 to extend or retract. When a telescopic support 4 has only two columns 41, the telescopic drive mechanism 42 is located in one of the columns 41, driving the other column 41 to extend or retract. When a telescopic support 4 has three or more columns 41, the telescopic drive mechanism 42 is located in one of the columns 41. After the telescopic drive mechanism 42 is activated, it first drives the column 41 at the other end to extend or retract. Then, in the direction from the other end to the end where the telescopic drive mechanism 42 is located, the columns 41 closest to the other end are sequentially driven to extend or retract relative to the end where the telescopic drive mechanism 42 is located, starting from the column 41 closest to the other end.

[0035] In this embodiment, the connection structure between every two adjacent columns 41 is identical. For example, as shown... Figure 3 As shown, each pair of adjacent columns 41 includes a first column 411 and a second column 412. One end of the telescopic drive mechanism 42 is disposed inside the first column 411, and the other end of the telescopic drive mechanism 42 is fixedly connected to the top end of the second column 412.

[0036] In use, the control valve is opened, and the high-pressure delivery main pipe and high-pressure delivery branch pipe deliver high-pressure water to the high-pressure nozzle 2. The high-pressure nozzle 2 washes the heat exchange fins 52. Then, the telescopic drive mechanism 42 is activated. The telescopic drive mechanism 42 drives the base 1 through the column 41. The base 1 slides along the inner triangle of the cooling triangle under the support of the support roller 3. Through the sliding of the base 1, the high-pressure nozzle 2 washes the heat exchange fins 52 one by one.

[0037] Furthermore, the high-pressure nozzle 2 in this embodiment can also be configured as a rotatable structure.

[0038] Specifically, such as Figure 2 As shown, the high-pressure nozzle 2 includes a connecting ball 21 and a nozzle 23 rotatably mounted on the connecting ball 21.

[0039] The connecting ball 21 is located on the isosceles side of the base 1, and has a first conveying hole 22 for high-pressure water to pass through. The first conveying hole 22 is connected to the high-pressure conveying branch pipe.

[0040] The nozzle 23 is trumpet-shaped, with a second delivery hole 24 inside for high-pressure water to pass through. The second delivery hole 24 is connected to the first delivery hole 22. The inner wall of the end of the nozzle 23 connected to the connecting ball 21 has a curved surface structure adapted to the connecting ball 21. The outer wall of the connecting ball 21 matches the curved inner wall of the nozzle 23, thereby realizing the angle adjustment of the nozzle 23. By adjusting the angle of the nozzle 23, the high-pressure water can further fully cover the heat exchange fins 52 during spraying. Damping pads 25 are provided on both the outer wall of the connecting ball 21 and the curved inner wall of the nozzle 23. The damping pads 25 not only increase the stability of the connection and prevent the nozzle 23 from sliding at will, but also prevent high-pressure water from leaking through the connection. A through hole 26 for high-pressure water to pass through is opened at the end of the nozzle 23 away from the connecting ball 21.

[0041] Furthermore, in this embodiment, the support roller 3 includes a support rod 31 and a roller 32 disposed on the support rod 31.

[0042] One end of the support rod 31 is fixedly mounted on the base 1, and the other end is fixedly connected to the roller 32. The support rod 31 is a telescopic structure. Its specific structure is similar to that of the telescopic support column 4 in this application.

[0043] The roller 32 is a magnetic roller 32, which uses the magnetism of the cooled triangular metal structure to enhance the attraction force and prevent the roller 32 from deviating during the sliding process.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
