Description

Technical Field

[0001] The utility model relates to the field of cooling towers, in particular to a water-cooled tower with a water outlet pipe that is convenient to clean. Background Art

[0002] Water-cooled towers play a crucial role in industrial and air-conditioning refrigeration systems. They dissipate waste heat through evaporation to cool down the cooling water for reuse. However, in the water outlet pipes of water-cooled towers, the accumulation of sediment is a common problem, which not only affects the cooling efficiency but also may bring a series of hazards.

[0003] The working principle of a water-cooled tower is to reduce the temperature of the cooling water carrying waste heat through heat exchange with air inside the tower. During this process, water molecules evaporate into the air, and the kinetic energy of the remaining water molecules decreases, resulting in a drop in water temperature. However, the evaporation also increases the concentration of dissolved minerals and other impurities in the water, which are prone to deposit in the water outlet pipe, forming sediment. In addition, the drift phenomenon in the water-cooled tower, that is, water molecules carrying impurities due to the action of wind, will also deposit in the pipe, further exacerbating the sediment problem.

[0004] The accumulation of sediment in the water outlet pipe of a water-cooled tower will cause several serious problems. First, the sediment will block the water flow, reduce the contact area between water and air, thereby reducing the heat exchange efficiency and affecting the cooling effect of the cooling tower. Second, the long-term accumulation of sediment may cause partial or complete blockage of the pipe, affecting the normal flow of cooling water, and even leading to system failure in severe cases. In addition, the presence of sediment will also increase the maintenance cost of the system because these sediments need to be cleaned regularly.

[0005] In the prior art, for example, the utility model with the publication number CN214344621U discloses a sewage treatment device for a water-cooled tower. In this device, the impeller rotates to make the sediment enter the sediment hopper from the water-cooled tower. For the sewage treatment device of the water-cooled tower of the present utility model, the mechanical force generated by the rotation of the impeller controls the flow state and velocity of the water flow, accelerates the circulation, so that the dust and sand in the water quickly precipitate in the sediment hopper, avoiding the abrasion and blockage of the pipe network caused by the dirt in the water entering the pipe network, reducing the overhaul and replacement of the sewage treatment device of the high water-cooled tower, improving the service life and practicability of the sewage treatment device of the water-cooled tower, and ensuring the long-term stable operation of the circulating water system. However, the applicability of the above device is not strong and cannot meet the general needs. Summary of the Utility Model

[0006] To solve the problems existing in the prior art, the purpose of the present utility model is to disclose a water cooling tower with a water outlet pipe that is convenient to clean, overcoming the problems of the traditional straight-through water outlet pipe, which is prone to sediment deposition and blockage or affecting the water outlet of the water outlet pipe, facilitating the maintenance of the pipe at any time, and designing multiple maintenance nodes to facilitate the inspection and repair of blockages at any position.

A water distribution pipeline is supported between the lower side of the fan and the packing chamber through a support frame. The water distribution pipeline is communicated with the water inlet pipe. The bottom of the packing chamber is provided with a water outlet, and the water outlet is connected to a water outlet pipe unit. The water outlet pipe unit includes: a vertical pipe with one end communicated with the water outlet, and the other end of the vertical pipe is communicated with the middle section of a first-level maintenance pipe. The first-level maintenance pipe includes an inclined pipe section and a horizontal pipe section connected in sequence. A maintenance cover is provided at the top of the inclined pipe section through flange connection. The first-level maintenance pipe is communicated with a sedimentation tank through a second-level maintenance pipe. Both ends of the second-level maintenance pipe are respectively connected to the first maintenance pipe and the sedimentation tank through flange connection.

[0008] Further, a plurality of vertical rods perpendicular to the surface of the maintenance cover are also provided on the maintenance cover.

[0009] Further, the vertical rods are threaded steel or iron rods.

[0010] Further, the length of the vertical rods in the first-level maintenance pipe is not shorter than the position where the vertical pipe is connected to the inclined pipe section.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The specific implementation methods of the utility model are further described in detail below in combination with the accompanying drawings. However, the following embodiments only list preferred embodiments, which only serve to explain and help understand the utility model and cannot be understood as limiting the utility model.

[0026] refer to Figures 1-5 A water-cooling tower with an outlet pipe that is easy to clean is basically similar to the existing water-cooling tower structure, including a stuffing bin 4 surrounded by a bottom plate 1, a side plate 2 and a top plate 3, a wind tube 5 is provided in the middle of the top plate, a motor 8 supported by a motor bracket 6 for driving a fan 7 to rotate is provided inside the wind tube, a water distribution pipeline 10 is supported by a support frame 9 between the lower side of the fan and the stuffing bin, the water distribution pipeline is communicated with a water inlet pipe 11, and a water outlet 12 is provided at the bottom of the stuffing bin.

[0027] The key is that the water outlet is connected to the water outlet pipe unit, and the water outlet pipe unit includes: a vertical pipe 13 with one end connected to the water outlet, and the other end of the vertical pipe is connected to the middle section of the first-level inspection pipe 14, and the first-level inspection pipe 14 includes an inclined pipe section 141 and a horizontal pipe section 142 connected in sequence, and a flange-connected inspection cover 143 is provided on the top of the inclined pipe section. The first-level inspection pipe 14 is connected to the sedimentation tank 16 through the second-level inspection pipe 15, and the two ends of the second-level inspection pipe 15 are respectively connected to the first inspection pipe and the sedimentation tank through flange connections.

[0028] The water to be cooled is transported to the water distribution pipeline through the water inlet pipe. The water distribution pipeline sprays the water into the packing bin. Driven by the motor, the fan promotes the circulation of air in the packing bin to cool down the high-temperature circulating water. The cooled cold water is collected into the water outlet pipe unit through the water outlet. By improving the water outlet pipe unit, the water outlet of the water cooling tower is connected to the first-level inspection pipe and the second-level inspection pipe with special structures through vertical pipes and then connected to the sedimentation tank. The inspection cover of the first-level inspection pipe can be disassembled and assembled for rapid maintenance, or the entire pipeline can be unblocked by the overall disassembly and assembly of the second-level inspection pipe. In addition, the setting of the sedimentation tank is convenient for cleaning the sediment in the sedimentation tank to prevent it from being circulated into the filler in the packing bin.

[0029] Preferably, reference Figure 5 The inspection cover 143 is also provided with a plurality of vertical rods 144 perpendicular to the inspection cover surface. The vertical rods are threaded steel or iron rods. The length of the vertical rods in the first-level inspection pipe is not shorter than the position where the vertical pipe 13 and the inclined pipe section 141 are connected.

[0030] A number of vertically arranged vertical rods are provided on the inspection cover, extending to the position where the vertical pipe and the inclined pipe section are connected. By using the vertical rods as the crystallization centers, the precipitation of inorganic salts is promoted and the inorganic salts are aggregated on the vertical rods. In this way, not only the amount of precipitates at subsequent nodes can be reduced, but also the precipitates on the vertical rods can be cleaned in time by removing the inspection cover.

[0031] On the basis of any of the above embodiments, preferably, the sedimentation tank includes a vertical tank body 161 and a sedimentation tank bottom 162 that tapers inward. A partition 163 is further provided in the sedimentation tank. An overflow groove 164 is provided on the partition.

[0032] The inwardly tapering tank bottom facilitates the sedimentation and subsequent cleaning of the precipitates. The presence of the partition and the setting of the overflow groove promote the sedimentation of the precipitates to a certain extent.

[0033] Referring to a general water cooling tower, a louver 17 is further provided at the bottom of the packing bin to facilitate heat dissipation. A stairway 18 is also included, and the stairway communicates with the top plate 3 to facilitate the maintenance of the top. A stamping protrusion 19 is further provided on the side plate 2, which can achieve noise reduction to a certain extent.

Without departing from the spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
