Description

Technical Field

[0001] The utility model relates to the field of thermal power generation cooling and flushing equipment, in particular to a pipe arrangement device for an air-cooled island flushing system. Background Art

[0002] The air-cooled island operates outdoors for a long time, and impurities such as fine sand, dust in the air, and sundries generated by strong winds accumulate on the radiator fins. This not only hinders heat exchange but also affects the exhaust of the fan, resulting in a reduction in the efficiency of heat exchange. In severe cases, it directly affects the normal power generation efficiency of the air-cooled generator set. Therefore, it is necessary to regularly flush the radiator fins of the air-cooled island to improve the unit efficiency.

[0003] Most of the existing air-cooled island flushing systems use flushing trolleys. The flushing trolleys are equipped with several nozzles and generally use manual or automatic flushing methods. Since the flushing trolley needs to make a reciprocating motion up and down on the basis of walking one left-right step distance on each flushing ladder, the failure rate is high, the flushing time is long, and the efficiency is low.

On the premise of meeting the flushing pressure of the nozzles 4, corresponding to the preferred embodiment of the present utility model, the specific number of at least two sections of water outlet pipes 10 is 2 sections.

[0027] As Figure 2 shown, the pipe assembly 1 further includes a connecting pipe 11 and a water inlet 12 connected to a high - pressure water source. The connecting pipe 11 is simultaneously communicated with the two sections of water outlet pipes 10 and is communicated with the water inlet 12. An electric valve 2 is installed between each section of water outlet pipe 10 and the water inlet 12. Corresponding to the preferred embodiment of the present utility model, the electric valve 2 is preferably a high - pressure electric ball valve for controlling the opening or closing of the water outlet pipe 10. To ensure the flushing pressure during the flushing process of the heat - dissipating fins 7, the electric valves 2 connected to each section of water outlet pipe 10 are opened in turn, and the corresponding water outlet pipes 10 are switched to work in turn. The high - pressure water flowing into the connecting pipe 11 enters the section of water outlet pipe 10 through the opened electric valve 2 for high - pressure flushing operation, realizing sectional flushing. For the convenience of installation, both the water inlet 12 and the electric valve 2 are located at the lower end of the heat - dissipating fins 7.

[0028] The pipe arrangement device further includes a plurality of nozzle seats 3 and nozzles 4 corresponding to the number of the plurality of nozzle seats 3. Corresponding to the preferred embodiment of the present invention, the nozzle 4 is preferably a high-pressure nozzle, and the water pressure is 6-8 Mpa, which can easily wash the heat dissipation fins 7 clean. The plurality of nozzle seats 3 are fixed to the water outlet pipe 10 by welding and are evenly arranged on the water outlet pipe 10 along the height direction of the area to be cleaned 70. A seal is provided between the nozzle seat 3 and the nozzle 4 and they are connected by threaded sealing. Corresponding to the preferred embodiment of the present invention, the number of the plurality of nozzles 4 is 18-22. The nozzle 4 always remains perpendicular to the surface of the heat dissipation fins 7. According to the distance between the water outlet pipe 10 and the heat dissipation fins 7 and the spraying angle of the nozzle 4, corresponding to the preferred embodiment of the present invention, the distance between adjacent nozzles 4 is 280-320 mm.

[0029] As Figure 3 and Figure 4 shown in the figure, the air-cooled island further includes moving mechanisms 8 respectively arranged at the upper and lower ends of the heat dissipation fins 7, and the pipe arrangement device further includes a flushing ladder 5. The moving mechanism 8 includes an upper fixing plate 80 and a lower fixing plate 81. The flushing ladder 5 is arranged along the surface of the heat dissipation fins 7, and both ends are fixedly connected to the upper fixing plate 80 and the lower fixing plate 81 by screws respectively.

[0030] As Figure 5 shown in the figure, the pipe arrangement device further includes a pipe fixing clamp 6; the pipe fixing clamp 6 is a U-shaped welding part, including two groups of identical first fixing blocks 60 and second fixing blocks 61. The two groups of first fixing blocks 60 are respectively fixedly connected to the inner walls on both sides of the flushing ladder 5 by screws; both ends of the second fixing block 61 are welded to the two groups of first fixing blocks 60; the bottom of the second fixing block 61 is fixedly connected to the pipe assembly 1 by a U-shaped clamp, so that the pipe assembly 1 and the flushing ladder 5 always remain relatively stationary and the distance to the surface of the heat dissipation fins 7 remains unchanged and is always parallel.

[0031] During operation, the high-pressure water source is connected to the water inlet 12, the high-pressure water enters the connecting pipe 11, the upper electric valve 2 is opened, the high-pressure water enters the right water outlet pipe 10, and is sprayed out from the nozzle 4 connected to the right water outlet pipe 10 to wash the upper area to be cleaned 70 corresponding to the right water outlet pipe 10 clean; the lower electric valve 2 is opened, the high-pressure water enters the left water outlet pipe 10, and is sprayed out from the nozzle 4 connected to the left water outlet pipe 10 to wash the lower area to be cleaned 70 corresponding to the left water outlet pipe 10 clean. The two electric valves 2 are opened alternately to separately wash the area to be cleaned 70 corresponding to each section of the water outlet pipe 10. There is no need to add an external trolley to move up and down repeatedly to wash the surface of the heat dissipation fins 7, which saves time and improves efficiency.

[0032] The pipe arrangement device of an air-cooled island flushing system according to an embodiment of the present utility model flushes the distribution of heat dissipation fins by using two sections of water outlet pipes, which not only ensures that the water pressure can flush the heat dissipation fins cleanly, but also saves time and improves work efficiency. The flushing ladder and the pipe arrangement assembly are fixedly connected by pipe fixing clamps, so that the flushing ladder and the pipes always remain relatively stationary, improving the stability of the pipe arrangement device during use and reducing the failure rate. The two sections of water outlet pipes are communicated with the same water inlet through connecting pipes, and the structure is simple. By installing high-pressure electric ball valves on each section of the water outlet pipe to control the opening and closing of each section of the water outlet pipe, it can not only realize the remote control of the pipe arrangement device, but also realize the zonal flushing of the heat dissipation fins, which is convenient and fast.
