Description

Technical Field

[0001] This application relates to the field of cooling tower technology, and in particular to a cooling tower equipped with a defogging device. 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 cooling principle utilizes the heat exchange between water and air to generate steam. The steam evaporates, carrying away heat through evaporation, convection, and radiation, thus dissipating waste heat generated in industrial processes or refrigeration and air conditioning systems to lower the water temperature and ensure the normal operation of the system.

[0003] Chinese patent CN204286147U discloses a mist-eliminating and water-saving cooling tower, which consists of a tower body, an axial flow fan, an upper air inlet regulating window, a finned tube radiator, a water collector, and a packing layer. The technical solution adopted to solve its technical problems is as follows: a motor, gearbox, and reducer are added to the top of the tower body for transmission to meet the power requirements of the exhaust fan; a finned tube radiator and a matching upper air inlet regulating window are installed on the upper outer side of the tower body sidewall, and the height of the finned tube radiator and the upper air inlet regulating window is increased to the upper plane of the original cooling tower cooling packing. Waterproof louvers are installed on the inner side of the part of the finned tube radiator that overlaps with the height of the spray pipe; a grid-type finned tube water inlet and outlet are set at the lower end of the finned tube radiator, the outlet is connected to the water inlet pipe of the spray pipe inside the tower body, and the inlet is connected to the water inlet pipe of the cooling tower.

[0004] Regarding the aforementioned technologies, existing technologies utilize water collectors to eliminate fogging of water vapor. However, impurities in the water vapor adhere to the inside of the water collector. With prolonged use, the impurities on the water collector accumulate, forming scale that covers the surface of the water collector. Since fogging by the water collector mainly relies on the contact between the surface of the water collector and the water vapor to liquefy the water vapor, scale reduces the contact area between the water collector and the water vapor, thereby reducing the fogging efficiency of the cooling tower. Summary of the Invention

[0005] In order to improve the defogging efficiency of cooling towers, this application provides a cooling tower equipped with a defogging device.

[0006] The cooling tower equipped with an anti-fogging device provided in this application adopts the following technical solution:

[0007] A cooling tower equipped with an anti-fogging device includes a tower body. A connecting frame is provided at the top of the tower body, and a plurality of anti-fogging arc plates are connected in parallel on the connecting frame. The plurality of anti-fogging arc plates cover the interior of the tower body. Moving columns are slidably engaged at positions above and below the anti-fogging arc plates within the tower body. A driving assembly is provided on the tower body to drive the moving columns to move. The moving direction of the moving columns is parallel to the length direction of the anti-fogging arc plates. A cleaning cylinder is rotatably connected to the moving columns. The surface of the cleaning cylinder is provided with bristles. A rotating assembly is provided inside the tower body to drive the cleaning cylinder to rotate.

[0008] By adopting the above technical solution, during scale removal, the moving column is driven by the drive component, while the cleaning cylinder is driven to rotate by the rotating component. This allows the bristles to clean the surface of the defogging arc plate. The two sets of bristles work simultaneously to achieve the effect of removing scale from the surface of the defogging arc plate. Through the cooperation of the drive component and the rotating component, the cleaning cylinder moves and rotates simultaneously, and the two sets of bristles work together to clean the surface of the defogging arc plate, reducing the possibility of residual scale on the surface of the defogging arc plate, maximizing the contact area between the defogging arc plate and water vapor, and improving the defogging efficiency of the cooling tower.

[0009] Optionally, a limiting rail is connected to each end of the moving column inside the tower body, and a sliding block is connected to the end of the moving column. The sliding block is a rectangular block and slides within the limiting rail.

[0010] By adopting the above technical solution, the sliding direction of the moving column is limited by the cooperation of the limiting rail and the sliding block, thereby improving the moving stability of the moving column.

[0011] Optionally, the drive assembly includes a drive motor and a drive screw. The drive screw is rotatably connected to the tower body and parallel to the limiting rail. The drive screw passes through one of the sliding blocks and is threadedly engaged with the sliding block. The drive motor is mounted on the outer wall of the tower body and is coaxially connected to the drive screw.

[0012] By adopting the above technical solution, when the moving column is driven to move, the drive motor is started, causing the drive screw to rotate. Through the cooperation of the drive screw and the sliding block, the sliding block is moved, thereby achieving the effect of moving the moving column.

[0013] Optionally, the rotating assembly includes a connecting gear and a fixed rack. The connecting gear is connected to the cleaning cylinder, and the fixed rack is fixedly connected to the tower body and parallel to the moving direction of the moving column. The connecting gear meshes with the fixed rack.

[0014] By adopting the above technical solution, when the cleaning drum is rotated, the moving column drives the cleaning drum to move, and at the same time, through the cooperation of the connecting gear and the fixed rack, the cleaning drum can move and rotate.

[0015] Optionally, a cooler is installed on the tower body, and a plurality of cooling pipes are fixedly connected to the output end of the cooler, the cooling pipes passing through the plurality of the anti-fog arc plates.

[0016] By employing the above technical solution, water vapor liquefies upon contact with the defogging arc plate, but it also gradually transfers heat to the plate, causing its temperature to rise and thus reducing the liquefaction rate of water vapor. By supplying cold air to the cooling pipes through a refrigerator, the defogging arc plate is cooled, ensuring its temperature remains within a specific range and thus guaranteeing the liquefaction rate of water vapor.

[0017] Optionally, several louvers are provided on the side walls around the tower body near the bottom, and the height of the louvers gradually decreases from the outside to the inside.

[0018] By adopting the above technical solution, louvers are installed around the tower body to increase the ventilation efficiency inside the tower, thereby achieving the purpose of cooling water vapor and realizing the effect of defogging to a certain extent.

[0019] Optionally, the anti-fog arc plate is made of PVC material.

[0020] By adopting the above technical solution, PVC material has extremely high corrosion resistance and chemical resistance, which reduces the corrosion of the anti-fog arc plate by scale and extends the service life of the anti-fog arc plate.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. During scale removal, the moving column is driven by the drive component, while the cleaning cylinder is rotated by the rotating component. This allows the bristles to clean the surface of the defogging arc plate. Both sets of bristles work simultaneously to effectively remove scale from the surface of the defogging arc plate. The cooperation between the drive and rotating components ensures that the cleaning cylinder moves and rotates simultaneously, and the two sets of bristles work together to clean the surface of the defogging arc plate, reducing the possibility of residual scale and maximizing the contact area between the defogging arc plate and water vapor, thus improving the defogging efficiency of the cooling tower.
