Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to a cooling tower that is easy to clean. Background Technology

[0002] Cooling towers, as a type of cooling device, are widely used in various fields such as steel metallurgy, power electronics, machining, and air conditioning systems.

[0003] Cooling towers typically consist of several parts, including a water collection tank, a ventilation tower, and water distribution pipes. Cooling water carrying waste heat is pumped into the distribution pipes of the cooling tower. Sprayers on the pipes evenly distribute the water from top to bottom onto the packing material, forming a water film. Simultaneously, the water exchanges heat with the dry air rising from the bottom of the ventilation tower, evaporating and carrying away heat. The cooled water then drips into the bottom water collection tank for continued recycling.

[0004] Packing material is a crucial component of cooling towers, used to increase heat dissipation and extend the residence time of cooling water. However, because the packing material in the aforementioned cooling tower structure is in direct contact with the cooling water, after prolonged use, a large amount of scale, algae, silt, and other impurities accumulate on it, severely affecting the heat exchange efficiency of the cooling tower. Therefore, regular flushing is necessary. Currently, the most common flushing method is to remove the packing material from the cooling tower and then manually flush it. Although this method can remove impurities from the packing material, the cooling tower cannot function properly during the disassembly and flushing process, leading to a decrease in cooling efficiency. Furthermore, the manual removal of impurities after disassembly is cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0005] The purpose of this invention is to provide a cooling tower that is easy to clean, so as to solve the problems mentioned in the background art.

[0006] The technical solution adopted in this utility model is:

[0033] Compared with the prior art, the beneficial effects of this utility model are:

[0034] In this invention, cooling water carrying waste heat is placed inside the packing material through heat exchange tubes, thus avoiding direct contact between the cooling water and the packing material for heat dissipation. This prevents impurities such as scale, algae, and silt from adhering to the packing material. While the cooling water and packing material are not in direct contact, a flushing device further cleans the packing material, simultaneously removing heat from the heat exchange tubes. This invention eliminates the need to interrupt the normal operation of the cooling tower during packing material cleaning and also eliminates the need for manual flushing, making operation convenient and improving the cooling efficiency of the cooling tower.

[0045] 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.

[0046] Given that in the current technology, the packing material in the cooling tower structure is in direct contact with the cooling water, resulting in the accumulation of a large amount of scale, algae, silt and other impurities on the packing material, and the need for manual disassembly and flushing, the cooling tower cannot work properly, resulting in low cooling efficiency, cumbersome operation, and time and labor costs.

[0047] like Figures 1-2 As shown, this utility model embodiment provides a cooling tower that is easy to clean, including: a tower body 1, which has a cavity inside, the cavity being composed of a heat exchange cavity 11, a water collection cavity 12 and an exhaust cavity 13.

[0048] The heat exchange chamber 11 and the exhaust chamber 13 are adjacent to and connected to each other, and the water collection chamber 12 is located below the heat exchange chamber 11 and the exhaust chamber 13 and is connected to the heat exchange chamber 11 and the exhaust chamber 13.

[0049] A fan 5 is installed at the top of the exhaust chamber 13. The fan 5 sends the air in the exhaust chamber 13 to the upper atmosphere to prevent backflow.

[0050] The heat exchange chamber 11 contains a packing cavity filled with packing 2. A heat exchange tube 3 is installed within the packing 2. The two ends of the heat exchange tube 3 are an inlet 31 and an outlet 32, both extending outside the heat exchange chamber 11, i.e., outside the cooling tower. The medium inside the heat exchange tube 3 is cooling water carrying waste heat. The heat exchange tube 3 separates the cooling water from the packing 2, thereby reducing the generation of scale, algae, silt, and other impurities on the packing 2.

[0051] Opposite to the packing chamber, a flushing device 4 is movably installed in the heat exchange chamber 11. The flushing device 4 performs a top-down flushing action on the packing 2. During the flushing process, high-pressure water comes into full contact with the packing 2 and the heat exchange tube 3, removing impurities from the packing 2 and heat from the heat exchange tube 3. The wet packing 2 further increases the heat dissipation of the heat exchange tube 3.

[0052] Multiple air inlets (not shown in the figure) are provided on one side of the heat exchange chamber 11, and multiple air outlets (not shown in the figure) are provided on the other side of the heat exchange chamber 11 opposite to the air inlets. The heat exchange chamber 11 is connected to the exhaust chamber 13 through the air outlets. Dry air from outside the tower body 1 enters the packing chamber through the air inlets, and comes into full contact with the heat exchange tubes 3 and packing 2 after being washed by the flushing device 4. After removing the heat from the heat exchange tubes 3, the humid air enters the exhaust chamber 13 through the air outlet under the action of the fan 5. Then, the humid air in the exhaust chamber 13 is sent to the upper atmosphere by the fan 5 to prevent backflow, and dry air is continuously drawn in through the air inlets to provide a constant flow of dry air, further realizing continuous heat dissipation of the heat exchange tubes 3.

[0053] Specifically, such as Figure 1 As shown, the rinsing device 4 includes several parts such as: a drive assembly 41, a lead screw 42, a lead screw nut 43, a fixed round rod 44, a sliding bushing 45, a lifting plate 46, a rinsing pipe 47, a spray pipe 48, and multiple high-pressure rinsing heads 49.

[0054] The drive assembly 41 is mounted on the wall of the heat exchange chamber 11. A lead screw 42 is rotatably mounted on one side wall of the heat exchange chamber 11 via a fastening bearing and is connected to the drive assembly 41. A lead screw nut 43 is movably fitted onto the lead screw 42. A fixed round rod 44 is mounted on the other side wall of the heat exchange chamber 11, opposite to the lead screw 42. A sliding bushing 45 is movably fitted onto the fixed round rod 44. A lifting plate 46 is installed between the lead screw nut 43 and the sliding bushing 45. A flushing pipe 47 is installed at the end of the lifting plate 46 facing the packing 2 and is connected to a flexible hose 50 outside the heat exchange chamber 11.

[0055] Multiple high-pressure flushing heads 49 are evenly installed on the flushing pipe 47, parallel to the packing material 2 but not in contact with it. Optionally, the high-pressure water pressure sprayed by the high-pressure flushing heads 49 can be 15 MPa to 20 MPa, and the distance between the high-pressure flushing heads 49 and the packing material 2 can be 160 mm to 180 mm. At this pressure and distance, the high-pressure water can completely remove impurities from the packing material 2 while effectively protecting the packing material 2 from damage by the impact force of the high-pressure water jet.

[0056] The spray pipe 48 is located outside the cooling tower. One end of it is connected to the water pump 6 and extends to an external water source, while the other end is connected to the flushing pipe 47 via a hose 50.

[0057] The drive assembly 41 drives the lead screw 42 to rotate, and the rotation of the lead screw 42 causes the lead screw nut 43 to move up and down reciprocally. The lead screw nut 43 drives the lifting plate 46 and the sliding bushing 45 to move up and down reciprocally along the fixed round rod 44. During the movement, the lifting plate 46 washes the packing 2 from top to bottom.

[0058] More specifically, the drive assembly 41 includes several parts such as a motor 411, a first bevel gear 412, and a second bevel gear 413.

[0059] The motor 411 is mounted outside the tower body 1 via a fixed platform. A first bevel gear 412 is mounted on the output shaft of the motor 411. A second bevel gear 413 is mounted on the lead screw 42 and meshes with the first bevel gear 412. The motor 411 drives the first bevel gear 412 to rotate, the first bevel gear 412 drives the second bevel gear 413 to rotate, and the second bevel gear 413 drives the lead screw 42 to rotate.

[0060] In use, the motor 411 is started, driving the first bevel gear 412 to rotate. The first bevel gear 412 drives the second bevel gear 413 to rotate, which in turn drives the lead screw 42 to rotate. The rotating lead screw 42 causes the lead screw nut 43 to move up and down reciprocally, thereby causing the lifting plate 46 and the sliding bushing 45 to move up and down along the fixed round rod 44. At the same time, the water pump 6 is started, and water from an external water source is transported through the spray pipe 48 to the flushing pipe 47. Then, multiple high-pressure flushing heads 49, in conjunction with the lifting plate 46, spray water from top to bottom onto the packing 2 and the heat exchange tube 3, thereby cleaning the packing 2. The cleaned water enters the water collection chamber 12 under the action of gravity.

[0061] In this application, since the cooling water and the packing 2 do not come into direct contact, the impurities on the packing 2 are mostly dust from the air brought in by the air inlet. Impurities brought directly by the cooling water, such as algae, scale, and silt, do not adhere to the packing 2. Therefore, in the cooling tower disclosed in this application, it is only necessary to remove the dust and impurities on the packing 2. The removal of dust and the heat exchange of the heat exchange tube 3 are carried out simultaneously by the flushing device 4, so that the dust can be removed in time and the situation of excessive accumulation of dust on the packing 2 can be avoided.

[0062] Furthermore, based on the purpose of saving water resources, the spray pipe 48 in this embodiment can also be connected to the water pump 6 and extended into the water collection chamber 12, so as to realize the recycling of water in the water collection chamber 12.

[0063] Furthermore, to further improve the heat exchange efficiency of the heat exchange tube 3 and the flushing effect on the packing 2, in this embodiment, a sprayer 7 is also provided directly above the packing 2 in the heat exchange chamber 11. The sprayer 7 is connected to the spray pipe 48, and the sprayer 7 sprays a vertically downward water flow, which is perpendicular to the water flow sprayed from the high-pressure flushing head 49 in the flushing pipe 47. The water flow has a wider coverage area, and the flushing effect on the packing 2 and the improvement of the heat exchange efficiency of the heat exchange tube 3 are more significant.

[0064] Furthermore, in order to reduce water loss, in this embodiment, a water separator 8 is also provided in the exhaust chamber 13 below the fan 5. The water separator 8 can separate the water droplets carried by the hot and humid air in the exhaust chamber 13 from the air. The separated water droplets fall into the water collection chamber 12 under the action of gravity, while the air is discharged through the fan 5.

[0065] 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.
