Description

Technical Field

[0001] The invention relates to the technical field of power plant cooling tower cleaning equipment, in particular to a double-nozzle reciprocating cleaning system for flushing an indirect cooling tower. Background Art

[0002] In cooling tower technology, since air-cooled units can save approximately 65% of water resources compared to wet-cooled units, my country has clearly proposed vigorously developing air-cooled units. However, after actual operation, air-cooled units have gradually revealed some shortcomings and problems. The most important one is that due to the long-term operation of intercooler towers in the open air, fine sand, dust, willow catkins and other debris in the air are deposited on the heat exchange fins. The accumulation of dust, dirt, and debris on the surface of the heat exchange fins of the intercooler towers not only reduces the area of the air channel, but also increases the heat transfer resistance of the heat exchange fins, greatly reducing the heat exchange capacity of the heat exchange fins, causing an increase in condenser vacuum and a decrease in unit efficiency. In addition, the dirt on the heat exchange fins can cause metal corrosion under the scale, shortening the service life of the heat exchange fins. Therefore, it is necessary to develop countermeasures to clean the dirt, reasonably perform high-pressure water flushing, and optimize the flow field distribution on the air side, which is of great significance to improving the heat exchange effect of the cooling triangle of the intercooler tower. Existing high-pressure cleaning systems for intercooler towers typically use fixed cleaning nozzles, which are unable to fully clean the innermost triangles and other triangular fin corners. Furthermore, existing cleaning racks have a large number of nozzles, resulting in high flow rates and reduced water pressure at the nozzle outlet. This prevents the water from fully penetrating the fins and opening up the heat exchange channels, resulting in inefficient cleaning. Summary of the Invention

[0003] The purpose of the present invention is to provide a double-nozzle reciprocating cleaning system for flushing an intercooler tower. The fan-shaped nozzle moves along the track on the side beam with the mobile nozzle assembly, from the outer side of the triangle to the innermost side of the triangle, and can perform all-round cleaning on the entire triangular fin surface, especially the top of the triangle where the innermost triangular fin surface intersects, which can also be flushed. This solves the problem that the fixed cleaning nozzle device cannot completely clean the innermost side of the triangle and other triangular fin corners, and has positive significance for improving the heat exchange effect of the cooling triangle of the intercooler tower.

[0004] To achieve the above-mentioned objectives, the present invention provides a double-nozzle reciprocating cleaning system for intercooler tower flushing, comprising a control assembly and a cleaning frame, wherein the cleaning frame comprises a triangular ring beam, the triangular ring beam comprises a side beam and a bottom beam, and a reinforcing beam parallel to the bottom beam is arranged inside the triangular ring beam; a left rotating plate and a right rotating plate are arranged parallel to the top surface of the triangular ring beam, the left rotating plate and the right rotating plate are perpendicular to the bottom beam, a water supply pipe assembly and a motor assembly are arranged in the middle position of the left rotating plate and the right rotating plate, and a rotating shaft assembly is installed at the tail end of the left rotating plate and the right rotating plate; a chain assembly is installed on the back of the triangular ring beam, and the motor assembly provides power to the chain assembly through an active sprocket, and a moving nozzle assembly is installed on the side beam.

[0030] Example 1

[0031] The present invention provides a double-nozzle reciprocating cleaning system for flushing an indirect cooling tower, the overall structure of which is as follows: Figure 1As shown, it includes a control component and a cleaning rack. The cleaning rack is made of aluminum and includes a triangular ring beam 1. The triangular ring beam 1 is composed of a side beam 11 and a bottom beam 12. A reinforcing beam 2 parallel to the bottom beam 12 is arranged inside the triangular ring beam 1. The side beams 11, bottom beam 12 and reinforcing beam 2 described in this embodiment are all made of aluminum alloy.

[0032] The top surface of the triangular ring beam 1 is parallel to the left rotating plate 3 and the right rotating plate 4. The left rotating plate 3 and the right rotating plate 4 are perpendicular to the bottom beam 12. The water supply pipe assembly 5 and the motor assembly 6 are arranged in the middle of the left rotating plate 3 and the right rotating plate 4. Figure 6 As shown. The water supply pipe assembly 5 is set on the reinforcement beam 2 and includes an inlet pipe 51 and an outlet pipe 52. The directions of the inlet pipe 51 and the outlet pipe 52 can be adjusted. The motor assembly 6 includes a motor mounting bracket 61 set on the bottom beam 12, and a reduction motor 62 is mounted on the motor mounting bracket 61.

[0033] A rotating shaft assembly 7 is installed at the tail end of the left rotating plate 3 and the right rotating plate 4; the rotating shaft assembly 7 includes a rotating shaft 71, which passes through the tail end of the left rotating plate 3 and the right rotating plate 4, and a bearing seat 72 for fixing the rotating shaft 71 is provided on the left side of the left rotating plate 3 and the right side of the right rotating plate 4, and a rotating sprocket 73 is installed at the left end of the rotating shaft 71.

[0034] A chain assembly 8 is installed on the back of the triangular ring beam 1, and the motor assembly 6 provides power to the chain assembly 8 through the driving sprocket 81. Figure 2 As shown, the triangular ring beam 1 includes driven sprockets 82 disposed at three corner positions. The driven sprockets 82 cooperate with chains 83. The chains 83 obtain power through the driving sprocket 81. The chains 83 are provided with a tensioner 84 and an anti-slip device 85. The tensioner 84 is used to dynamically adjust and maintain a constant tension state of the chain 83. The anti-slip device 85 is used to prevent the chain 83 from falling off, thereby avoiding possible damage to the equipment and nearby personnel.

[0035] A movable nozzle assembly 9 is installed on the side beam 11. Limit switches are set at both ends of the side beam 11. The limit switches are used to limit the moving distance of the movable nozzle assembly 9. When the movable nozzle assembly 9 on one side of the side beam 11 cleans the outermost side of the triangular fin, the movable nozzle assembly 9 on the other side just cleans the innermost side of the triangular fin. When one fan-shaped nozzle 94 moves to the tail end of the side beam 11, the other fan-shaped nozzle 94 moves to the top end of the side beam 11, triggering the limit switch. The trigger signal is transmitted to the control component through the background, and a cleaning cycle is completed. The movable nozzle assembly 9 is as shown in FIG. Figure 3 As shown, the details of the side beam 11 are as follows Figure 4 and Figure 5The movable nozzle assembly 9 includes a movable frame 91. A pulley 92 is provided between the movable frame 91 and the triangular ring beam 1. The movable frame 91 moves along the side beam 11 via a chain 83. A nozzle water inlet pipe 93 is installed on the movable frame 91. The nozzle water inlet pipe 93 supplies water to a fan-shaped nozzle 94. The fan-shaped nozzle 94 is a high-pressure nozzle used to clean the fins on both sides of the cooling triangle.

[0036] The control assembly includes a wide-angle camera 10 arranged parallel to the cleaning rack, a control box 14 for controlling the specific actions of the cleaning rack, and a wireless temperature measuring element. The installation positions of the wide-angle camera 10 and the control box 14 are as follows: Figure 9 As shown. The control box 14 adjusts the cleaning speed by controlling the speed of the reduction motor 62. The wide-angle camera 10 is used to monitor the cleaning screen; the wireless temperature measuring element is used to monitor the temperature of the cooling triangle; the results of the wide-angle camera 10 and the wireless temperature measuring element are transmitted to the control room in real time and used as the basis for adjusting the water pressure and water output. The monitoring display interface of the control room can display the cleaning status, effect and cooling triangle temperature and other related parameters of the intercooler, so that the management personnel can intuitively understand the real-time operation of the intercooler, analyze the data to determine the degree of dirtiness of the cooling triangle fins, and thus control the flushing pressure and flushing water volume, which can not only fully flush and clean but also save water to the maximum extent. The detailed control principle of the entire cleaning system is as follows. Figure 10 shown.

[0037] When the dual-nozzle reciprocating cleaning system for flushing an intercooler tower described in this example is in operation, the water inlet pipe 51 is connected to an external water source, and the nozzle inlet pipe 93 of the movable nozzle assembly 9 is connected to the water outlet pipe 52 through a high-pressure hose. The dual-nozzle reciprocating cleaning system for flushing an intercooler tower described in this example is installed on an aluminum alloy slide and placed horizontally inside the cleaning triangle, such as Figure 7 and Figure 8 As shown. The movable nozzle assembly 9 is arranged on the side beam 11, with the left movable nozzle assembly 9 placed at the track head of the left side beam 11 and the right movable nozzle assembly 9 placed at the track tail of the right side beam 11. When the reduction motor 62 drives the chain 83 to move through the active sprocket 81, the left movable nozzle assembly 9 moves toward the tail of the left side beam 11 and the right movable nozzle assembly 9 moves toward the head of the right side beam 11. At the same time, the fan-shaped nozzle 94 sprays high-pressure water to perform mobile flushing on the fins on both sides. After completing the cleaning of one layer of fins, that is, completing one cleaning cycle, the control component issues a command, and the entire cleaning rack moves up one layer for the next round of cleaning.

[0038] The cleaning rack can be moved up and down by the lifting mechanism of the aluminum alloy slide, providing comprehensive cleaning of the triangular fins. After cleaning one set of fins, the cleaning rack is rotated to a vertical position by the rotating shaft assembly 7 and moves to the next fin with the aluminum alloy slide, repeating the cleaning process for the previous fin. This cycle completes the cleaning of all cooling fins in the intercooler.

[0039] Therefore, the present invention adopts the above-mentioned double-nozzle reciprocating cleaning system for flushing the intercooler tower, which not only realizes the function of comprehensive cleaning of the triangular fins, but also realizes the function of moving the fan-shaped nozzle back and forth in the triangle for cleaning; the fan-shaped nozzle moves along the track on the side beam with the mobile nozzle assembly, from the outside of the triangle to the innermost side of the triangle, and can perform all-round cleaning of the entire triangular fin, especially the top of the triangle where the innermost triangular fins intersect, which can also be flushed, solving the problem that the fixed cleaning nozzle device cannot completely clean the innermost side of the triangle and other triangular fin corners, and has positive significance for improving the heat exchange effect of the cooling triangle of the intercooler tower; at the same time, the number of nozzles is reduced, the flushing pressure is increased, the water consumption is significantly reduced, and the cleaning cost is reduced; the wide-angle camera is combined with the wireless temperature measuring element to adjust the water pressure and water output in real time, which significantly improves the cleaning effect; the entire cleaning rack is made of aluminum, which not only reduces the weight of the cleaning system, but also further reduces the cost compared to the traditional cleaning rack made of stainless steel.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solutions of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
