Description

Technical Field

[0001] The present application relates to the technical field of cleaning sectors of intercooler towers, and in particular to an automatic cleaning and cooling device. Background Art

[0002] An indirect air cooling tower is a device used to cool process fluids. It is commonly found in power stations, factories and other industrial fields. It is mainly used to cool the exhaust steam in thermal power units that is discharged to the condenser after the turbine has completed work. Circulating water is used as an intermediate medium. The circulating water with increased temperature is brought to the cooling triangle of the indirect cooling tower sector by the circulating water pump. The cooling triangle consists of multiple pipes filled with circulating water and heat dissipation fins, which increases the contact area between water and air. When the indirect cooling tower blows the air at the bottom into the tower, the cold air passes through the cooling triangle and exchanges heat with the circulating water in the pipe. The heat of the circulating water is transferred to the air, which increases the air temperature and reduces the temperature of the circulating water, effectively reducing the temperature of the high-temperature fluid and ensuring the stability and safety of the production environment.

[0003] When the cooling triangles in the fan blade area of ​​the intercooler are working, their surfaces often absorb impurities and dust in the air, causing a significant drop in cooling efficiency. In addition, they often need to be cleaned regularly to achieve the cooling effect. When used in hot weather, cleaning is more frequent. However, due to the complex operation of existing cleaning devices, their failure rate is high, and the inspection and maintenance costs are high. Moreover, workers are still required to clean them during fault repairs.

[0027] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0028] like Figure 1 As shown, the automatic cleaning and cooling device is mainly suitable for cleaning and cooling the heat exchange surface of the fan blade area of ​​the intercooling tower. The device is arranged in the fan blade area 2 of the intercooling tower 1, and can be installed in a fixed manner or in a mobile manner. If a fixed installation is adopted, one device needs to be installed in each fan blade area 2. If a mobile installation is adopted, one device is installed, and the cleaning can be performed by moving the device to each fan blade area 2;

[0029] like Figure 2 and Figure 3 As shown, it specifically includes a bottom plate 3 and a top plate 4, which are respectively arranged in the lower and upper end spaces of the fan blade area 2, and a spray mechanism and a driving mechanism are arranged between the bottom plate 3 and the top plate 4, and the two heat exchange surfaces of the fan blade area 2 are sprayed, flushed and cooled by the spray mechanism, and the spray mechanism is driven up and down by the lifting mechanism to spray;

[0030] The lifting mechanism can adopt the existing technology of suspension lifting or vertical lifting driven by a motor;

[0031] like Figure 2 and Figure 5 As shown, the spray mechanism includes a triangular spray frame 5, a spray pipe 6, a water injection pipe 7, and a water supply pipe 8. The triangular spray frame 5 is triangular in shape. The triangular outer side of the triangular spray frame 5 has two adjacent spray surfaces, and the spray pipe 6 is installed on the two adjacent spray surfaces. The nozzle of the spray pipe 6 is opposite to the heat exchange surface of the fan blade area 2. The water injection pipe 7 is arranged in the inner circle of the triangular spray frame 5. The water injection pipe 7 has at least two drain ports, and the two drain ports are respectively connected to the water inlet ends of the two spray pipes 6. The water injection pipe 7 has a water inlet, and the water inlet is connected to the water supply pump through the water supply pipe 8.

[0032] The spray mechanism is driven to rise and fall by the driving mechanism so that the spray mechanism can automatically rise and fall to clean the heat exchange surfaces on both sides of the fan blade area 2, thereby washing away the dust and impurities on the heat exchange surfaces. The fan blade area 2 can also be cooled to ensure that the vacuum degree of the steam turbine is maintained within the required range for a long time, which is beneficial to improving the working efficiency of the intercooler 1, and has excellent performance in energy saving and consumption reduction, effectively reducing energy consumption, and has a simple structure, convenient operation, and low failure rate, thereby reducing inspection and maintenance costs. No manual cleaning operation is required, which saves time and effort, is beneficial to improving the actual cleaning efficiency, avoids the risk of manual high-altitude operations, and is beneficial to the long-term safe and stable production of the enterprise.

[0033] Specifically, Figure 3 As shown, the lifting mechanism is a suspension lifting structure driven by a motor, including a winder 9, a guide wheel 10, and a sling 11. The winder 9 is installed on the upper end surface of the bottom plate 3, and the guide wheel 10 is installed on the lower end surface of the top plate 4. One end of the sling 11 is wound around the reel of the winder 9, and the other end of the sling 11 is a free end and passes through the guide wheel 10 upward and extends downward to be connected with the top of the water injection pipe 7. The winder 9 automatically winds and unwinds the sling 11, so that the sling 11 drives the spray mechanism to rise and fall, thereby facilitating the washing and cooling of the two heat exchange surfaces of the fan blade area 2;

[0034] Furthermore, there are two guide wheels 10, which are parallel to each other and are respectively arranged above the triangular spray frame 5 and the winder 9. The sling 11 passes through the two guide wheels 10 in sequence and is slidably connected with the wheel groove. Such a design makes the sling 11 more stable in suspending and lifting the spray mechanism, thereby improving the stability of actual cleaning and cooling.

[0035] Furthermore, if Figure 5 As shown, a lifting ring 17 is installed on the upper end surface of the water injection pipe 7, and the free end of the sling 11 is connected to the lifting ring 17, which facilitates the connection of the sling 11 to the spray mechanism;

[0036] In one embodiment, the number of the lifting rings 17 can be set to three and they are respectively set on the three corners of the triangular spray frame 5, and the free end of the sling 11 has three traction ropes, which are respectively connected to the three lifting rings 17, which is beneficial to improve the suspension stability of the triangular spray frame 5.

[0037] Specifically, Figure 5 As shown, the water injection pipe 7 includes a main pipe 71, a first branch pipe 72 and a second branch pipe 73. The main pipe 71 is arranged at the inner circle center of the triangular spray frame 5. The upper end of the main pipe 71 has three drainage pipes, and the lower end of the main pipe 71 has a water inlet pipe. The three drainage pipes are distributed in a trident. The two ends of the spray pipe 6 are respectively provided with a first water inlet and a second water inlet. The first branch pipe 72 is installed on the free end of one of the drainage pipes. The first branch pipe 72 has two drainage ports and is respectively connected to the first water inlet of the adjacent spray pipe 6. The free ends of the other two drainage pipes are each provided with a second branch pipe 73. The drainage outlet of the second branch pipe 73 is connected to the second water inlet of the adjacent spray pipe 6, one end of the water supply pipe 8 is connected to the water inlet pipe at the lower end of the main line 71, and the other end of the water supply pipe 8 is connected to the water supply pump. The cleaning water is pumped by the water supply pump, and the cleaning water is injected into the main line 71 through the water supply pipe 8. Through the three-pronged drainage pipe design at the upper end of the main line 71, the cleaning water is respectively injected into the spray pipes 6 on both sides through the first branch pipe 72 and the two second branch pipes 73, and the water pressure is shared, so that the flushing water pressure of the two spray pipes 6 is kept consistent. Combined with the suspension and lifting effect of the sling 11, the actual cleaning stability can be improved;

[0038] Furthermore, if Figure 2 and Figure 3 As shown, a fixing plate 14 is installed on one side of the bottom plate 3 and the top plate 4 close to the heat exchange surface of the fan blade area 2, and the upper and lower fixing plates 14 are connected by a support rod 15. The two corners of the triangular spray frame 5 located at the opening of the fan blade area 2 are provided with movable holes, and the triangular spray frame 5 is slidably sleeved on the support rod 15 through the movable holes. When the sling 11 tows and lifts the spray mechanism, the two corners of the rear end of the triangular spray frame 5 are respectively slidably sleeved with the two support rods 15, so that the rear end of the triangular spray frame 5 is very stable, which helps to maintain the balance during spray cleaning and prevent the triangular spray frame 5 from tipping over due to water pressure, thereby ensuring the normal operation of the device;

[0039] Furthermore, if Figure 2 and Figure 3As shown, a first auxiliary wheel 12 is installed at one outer corner of the triangular spray frame 5, and second auxiliary wheels 13 are installed at the other two outer corners of the triangular spray frame 5. The first auxiliary wheel 12 is located at the inner corner of the blade area 2 and is rollingly connected to the inner walls of the blade area 2 on both sides. The two second auxiliary wheels 13 are respectively arranged on both sides of the opening of the blade area 2, and the two second auxiliary wheels 13 are respectively rollingly connected to the outer sides of the inner walls of the blade area 2 on both sides, which can improve the lifting stability of the triangular spray frame 5 in the blade area 2, thereby improving the flushing stability, which is conducive to reducing the failure rate, thereby improving the actual cleaning efficiency and reducing the inspection and maintenance costs;

[0040] Furthermore, the contact surfaces between the first auxiliary wheel 12 and the second auxiliary wheel 13 and the blade area 2 are both non-working surfaces of the blade area 2 .

[0041] Specifically, Figure 3 and Figure 4 As shown, a water pipe storage box 16 is installed on the bottom plate 3, and the water supply pipe 8 is a hose and is stored in the water pipe storage box 16. One end of the water supply pipe 8 extends upward and is connected to the water inlet of the water injection pipe 7, and the other end of the water supply pipe 8 extends to the outside of the water pipe storage box 16 and is connected to the external water tank through a water supply pump. In the initial state, the triangular spray frame 5 is at the lowest point and is flush with the lower end of the fan blade area 2. At this time, the water supply pipe 8 is stored in the water pipe storage box 16. When the driving mechanism drives the triangular spray frame 5 to rise, it will drive the water supply pipe 8 to be pulled upward synchronously, so that the water supply pipe 8 gradually moves to the top of the water pipe storage box 16. When the triangular spray frame 5 moves to the top and is flush with the upper end of the fan blade area 2, the water supply pipe 8 is in the maximum extension state, which is convenient for the lifting and lowering of the spray mechanism and water supply;

[0042] Further, one end of the water supply pipe 8 located outside the water pipe storage box 16 is long enough to be connected to an external water tank, thereby facilitating water supply;

[0043] Furthermore, a water pipe winding assembly can be installed in the water pipe storage box 16, which can automatically reel in the water supply pipe 8 without causing compression and blockage to the water supply pipe 8. The water pipe winding assembly has a winding shaft, and the shaft end of the winding shaft has a resettable coil spring, so that the water supply pipe 8 is automatically reset when the triangular spray rack 5 is raised or lowered;

[0044] It should be noted that the water supply pipe 8 will not be repeatedly wound on the winding shaft, and the water supply pipe 8 is only wound in one layer on the outer circumference of the winding shaft, so as to avoid compression on the water supply pipe 8 and prevent clogging of the water pipe.

[0045] In one embodiment, Figure 4As shown, the device is a mobile installation and also includes a linear guide 18, which is arranged outside the bottom end of the intercooling tower 1, and the bottom plate 3 is installed on the movable end of the linear guide 18. The bottom plate 3 is driven to enter and exit the fan blade area 2 by the linear guide 18. The inside of the linear guide 18 has a lead screw driven by a motor, and the bottom plate 3 is installed on the slider end of the lead screw. The bottom plate 3 is driven to move horizontally by the linear guide 18, so that the bottom plate 3 can smoothly enter the fan blade area 2 under control for cleaning work, and can also be moved out of the fan blade area 2 after cleaning, and repeat the work of the next fan blade area 2, and the linear guide 18 can be moved around the bottom end of the intercooling tower 1 by manual or electric drive;

[0046] Specifically, Figure 4 As shown, the device also includes an annular guide rail 19, which is arranged on the outer periphery of the bottom end of the intercooling tower 1, and a linear guide rail 18 is installed on the movable end of the annular guide rail 19. The linear guide rail 18 and the bottom plate 3 thereon are driven by the annular guide rail 19 to move circumferentially along the outer periphery of the bottom end of the intercooling tower 1, so as to facilitate the movement of the device between multiple blade areas 2, so as to realize the circumferential automatic cleaning and cooling of multiple blade areas 2 on the intercooling tower 1 by one device, and multiple such devices can also be added, each device is responsible for multiple blade areas 2 of a sector section, so as to improve the actual cleaning efficiency, to a certain extent, it can also reduce the cost of use, and it is easy to manufacture and maintain, further reducing the production cost. At the same time, the low investment also makes it more economically feasible, easy to be widely used, safe and reliable in operation, ensuring the stable production, and reducing the risks and losses caused by equipment failure.

[0047] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
