Description
Technical Field
[0001] This invention relates to the field of cooling tower technology, and more particularly to a cooling tower with a circulating spray function. Background Technology
[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and release it into the atmosphere to lower the water temperature. Its principle is to utilize the heat exchange between water and air to generate steam. The steam evaporates and carries away the heat, achieving heat dissipation through evaporation, convection, and radiation. This process dissipates waste heat generated in industrial processes or refrigeration and air conditioning systems, thereby lowering the water temperature and ensuring the normal operation of the system. The device is generally cylindrical, hence the name cooling tower.
[0003] In existing cooling towers, after the cooling water evaporates, it encounters the top water collector and condenses into water droplets that fall into the water collection chamber below. During the fall, the water droplets pass through the water distribution tray. Over time, dirt accumulates on the water distribution tray, which can easily cause blockage. Moreover, this area is inconvenient to clean manually inside the cooling tower. Therefore, we need to consider how to solve this problem. Summary of the Invention
[0004] The purpose of this invention is to solve the problems in the background art by proposing a cooling tower with a circulating spray function.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A vertical water inlet riser is installed at the center of the water collection chamber, and a horizontal water inlet pipe is fixedly connected to the bottom of the water inlet riser. The end of the horizontal water inlet pipe away from the water inlet riser passes through the inner wall of the water collection chamber and is fixedly connected to a water pump.

The bottom of the cleaning scraper is provided with multiple vertical plates inserted into the gaps between the rings of the water spray tray, and the vertical plates do not contact the support rods supporting the water spray tray. The bottom of the inner wall of the cooling chamber is fixedly connected with a guide plate for guiding water flow from the edge of the inner wall of the cooling chamber into the water accumulation chamber.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0022] Reference Figure 1-4 A cooling tower with circulating spray function includes a water collection chamber 1, which is a circular pool for storing treated cooling water. The bottom of the water collection chamber 1 is provided with multiple support legs 2 to ensure stable operation of the cooling tower. A vertical water inlet riser 6 is provided at the center of the water collection chamber 1. A horizontal water inlet pipe 5 is fixedly connected to the bottom of the water inlet riser 6. The end of the horizontal water inlet pipe 5 away from the water inlet riser 6 passes through the inner wall of the water collection chamber 1 and is fixedly connected to a water pump 4. The water pump 4 pressurizes the cooling water and pumps it into the water inlet riser 6 through the horizontal water inlet pipe 5, so that the spray mechanism generates sufficient water pressure to produce a jet of water.
[0023] A support frame 7 is provided on the upper end of the inner wall of the water collection chamber 1. The support frame 7 consists of four connecting rods and a disc in the middle position. The bottom of the water inlet riser 6 is fixedly connected to the bottom plate of the water collection chamber 1, and the water inlet riser 6 passes through the support frame 7 and is fixedly connected to the side wall of the support frame 7. The support frame 7 and the bottom plate of the water collection chamber 1 ensure the stability of the structure of the water inlet riser 6.
[0024] The top of the water inlet riser 6 is equipped with a spray mechanism for converting water into jet fluid. The spray mechanism includes a water distribution pipe 15 sleeved on the top of the water inlet riser 6. The bottom of the water distribution pipe 15 is rotatably connected to the water inlet riser 6 via a bearing. The water distribution pipe 15 is cap-shaped and has four spray ducts 16 on its four sides. Each spray duct 16 has a nozzle 17 at its end. The nozzles 17 are all arranged clockwise towards the water inlet riser 6. The jet fluid can drive the water distribution pipe 15 to rotate around the water inlet riser 6, generating power.
[0025] The water distribution pipe 15 has a protrusion on its side wall below the spray duct 16. The protrusion is circular and has multiple vertical fixing rods 18 fixedly connected to its bottom. The fixing rods 18 are arranged at intervals around the water inlet riser 6. The bottom of the fixing rods 18 is fixedly connected to a fan 14. The rotation of the water distribution pipe 15 will drive the fan 14 to rotate. The fan 14 has a fan baffle 13 on its outside. The fan baffle 13 is narrow at the top and has a large opening at the bottom. The bottom side wall of the fan baffle 13 is fixedly connected to a fan bracket 21. The fan bracket 21 is composed of multiple connecting rods that connect the fan baffle 13 and the inner wall of the cooling chamber 3. It is a structure that fixes the fan baffle 13.
[0026] A water spray plate 9 is provided at the bottom of the cooling chamber 3. The water spray plate 9 is composed of multiple overlapping rings with gaps between them. After falling, the water droplets fall into the water collection chamber 1 through the gaps between the rings of the water spray plate 9. During this process, the water droplets are stabilized by secondary hot and cold air exchange. Multiple support rods are fixedly connected to the inner wall of the cooling chamber 3 at the bottom of the rings. A cleaning scraper 10 for removing dirt from the water spray plate 9 is provided on the water spray plate 9. Multiple vertical plates are inserted into the gaps between the rings of the water spray plate 9 at the bottom of the cleaning scraper 10. The vertical plates do not contact the support rods supporting the water spray plate 9, ensuring that the cleaning scraper 10 will not be hit by the support rods at the bottom when it rotates. A guide plate 12 is fixedly connected to the bottom of the inner wall of the cooling chamber 3 to guide the water flow from the edge of the inner wall of the cooling chamber 3 into the water collection chamber 1, preventing the water flow from seeping out of the tower through the lower edge of the cooling chamber 3.
[0027] The cleaning scraper 10 is fixedly connected to the bottom of the fan 14 via a connecting rod 11 at one end near the water inlet riser 6. The connecting rod 11 is an L-shaped rod, and the short side of the connecting rod 11 is parallel to the water inlet riser 6. A vertical rod is provided at the bottom of the long side of the connecting rod 11 near the cleaning scraper 10 and is fixedly connected to the top of the cleaning scraper 10. The cleaning scraper 10 is located below the fan baffle 13 to prevent the fan baffle 13 from affecting the rotation of the cleaning scraper 10. At the same time, a baffle is provided on the inner side of the water spray tray 9 to prevent water from falling into the water collection chamber 1 without passing through the water spray tray 9.
[0028] The cooling chamber 3 is fixedly connected to the top of the water collection chamber 1 by multiple vertical support rods to ensure the stability of the upper cooling chamber 3 structure. The upper end of the cooling chamber 3 has a hole, and a water collector 20 is fixedly connected in the hole. The water collector 20 is formed by multiple curved plates connected at intervals. It has the characteristics of exhausting hot and humid air while reducing water evaporation and running out of the tower. Dustproof louvers 8 are installed between the side wall of the water collection chamber 1 and the side wall of the cooling chamber 3 to prevent dust from entering the tower while ensuring that the fan 14 absorbs enough dry and cold air into the tower. The side wall of the water collection chamber 1 has a water outlet 19 to ensure that the treated cooling water is discharged from the water collection chamber 1 in a timely manner.
[0029] In use, the operator connects the water to be cooled to the water pump 4, which pressurizes the water and forces it into the horizontal inlet pipe 5. The cooling water then enters the vertical inlet pipe 6 through the horizontal inlet pipe 5, and then flows through the distribution pipe 15 at the top of the vertical inlet pipe 6 into each spray duct 16. There, the water is converted into spray fluid by the nozzles 17 on the spray duct 16 and ejected. The ejected fluid generates power, causing the nozzles 17 to rotate the spray ducts 16 around the vertical inlet pipe 6. This, in turn, causes the distribution pipe 15 to drive the fan 14 to rotate around the vertical inlet pipe 6. The centrifugal force generated by this rotation intensifies the spray fluid. At high speed, the fan 14 rotates and absorbs the dry and cold air from the outside through the dustproof louvers 8, which exchanges heat with the water mist inside the cooling tower. The humid and hot air after heat exchange is separated into small water droplets by the water collector 20 at the top of the tower and discharged outside the tower. The falling atomized water droplets gather on the water spray plate 9 and pass through the water spray plate 9, which transforms the water flow into a multi-layer water film and exchanges heat with the dry and cold air for the second time. Finally, it flows into the water collection chamber 1 at the bottom of the tower to complete the cooling process. At the same time, the fan 14 rotates and drives the cleaning scraper 10 to rotate through the connecting rod 11, preventing dirt from accumulating on the water spray plate 9. Finally, the treated water is discharged through the water outlet 19.
[0030] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
