Description

Technical Field

[0001] This utility model relates to the field of open cooling tower technology, specifically to an open cooling tower water collection and mist elimination device. Background Technology

[0002] An open cooling tower is a device that uses direct contact between water and air to exchange heat and achieve cooling by circulating cooling water. It is widely used in industrial and commercial fields. Its core principle is to use circulating cooling water sprayed onto the packing layer to form a water film, which fully contacts the counter-current or cross-current air. Through evaporative heat dissipation and convective heat transfer, the heat is released into the atmosphere, thereby reducing the water temperature and recycling it.

[0003] A search revealed an energy-saving open cooling tower disclosed in Chinese Utility Model Patent Publication No. CN217979895U. This energy-saving open cooling tower features a waterproof motor that drives the fan blades to rotate, simultaneously rotating the inner shell. The rotation of the inner shell generates centrifugal force, which evenly throws hot water from the drain holes onto the packing material, increasing the utilization rate of the packing material and thus improving cooling efficiency without significantly increasing energy consumption. The water collection basin can be unscrewed from the inside of the outer shell using a handle, allowing for easy inspection of both the inner side of the water collection basin and the inner side of the outer shell.

[0004] However, this energy-saving open cooling tower does not have a fog-eliminating structure. When the exhaust gas with high moisture content is not completely cooled, a large amount of white fog will be formed, which will have a serious impact on environmental pollution. At the same time, the device is not convenient for replacing the packing. Therefore, an open cooling tower water collection and fog-eliminating device is proposed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 An open cooling tower water collection and defogging device includes a base 1, a support rod 2 fixedly installed on the top of the base 1, a cooling tower body 3 fixedly installed on the left side of the support rod 2, a water collection and defogging structure 4 on the outside of the base 1, a fixing structure 5 on the outside of the base 1, and a cooling structure 6 on the inside of the cooling tower body 3.

[0025] The water collection and mist elimination structure 4 includes a rotating plate 401. The rotating plate 401 is rotatably connected to the top of the base 1. A telescopic rod 402 is fixedly installed on the top of the rotating plate 401. An installation ring 403 is fixedly installed at the output end of the telescopic rod 402. A collection box 404 is fixedly installed on the outer surface of the installation ring 403. A sealing ring 405 is fixedly installed on the top of the collection box 404. A filter plate 406 is movably connected inside the collection box 404. An air outlet pipe 407 is fixedly installed on the top of the cooling tower body 3. A semi-circular block 408 is fixedly installed inside the air outlet pipe 407. An activated carbon plate 409 is inserted into the semi-circular block 408. A fixed disc 410 is fixedly installed inside the air outlet pipe 407. A limit rod 411 is fixedly installed at the bottom of the fixed disc 410. A movable disc 412 is rotatably connected to the outer surface of the limit rod 411.

[0026] Furthermore, the fixed structure 5 includes a first motor 501, the first motor 501 is fixedly installed inside the support rod 2, a threaded rod 502 is rotatably connected inside the support rod 2, a lifting block 503 is threadedly connected to the outer surface of the threaded rod 502, an installation block 504 is fixedly installed on the right side of the lifting block 503, an electric slide rail 505 is fixedly installed inside the installation block 504, and an arc-shaped clamp 506 is provided on the outer surface of the electric slide rail 505.

[0027] Specifically, such as Figure 1 As shown, the bottom of the cooling tower body 3 is provided with a sealing groove that matches the sealing ring 405. When needed, the rotating plate 401 drives the telescopic rod 402 to rotate, thereby driving the two collection boxes 404 to rotate until one of the collection boxes 404 rotates to the bottom of the cooling tower body 3. Then, the telescopic rod 402 is opened to drive the collection box 404 to rise until it fits against the bottom of the cooling tower body 3, and a sealed space is formed by the sealing groove and the sealing ring 405.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, the first motor 501 is then turned on to drive the threaded rod 502 to rotate. The rotation of the threaded rod 502 drives the lifting block 503 to move, thereby causing the mounting block 504 to rise or fall. The movement of the mounting block 504 will cause the two arc-shaped clamps 506 to move. When the mounting block 504 drives the two arc-shaped clamps 506 to rise to the middle area of ​​the collection box 404 that is attached to the cooling tower body 3, the two electric slide rails 505 are opened to drive the two arc-shaped clamps 506 to move relative to each other. The two arc-shaped clamps 506 move closer to each other to clamp and fix the collection box 404, preventing the collection box 404 from being displaced by external forces during use.

[0029] Specifically, such as Figure 3 As shown, hot water is then sent into the hopper 603 inside the cooling tower body 3 through the inlet pipe. Then, the second motor 601 is turned on to drive the rotating rod 602 to rotate, thereby driving the hopper 603 to rotate. The rotation of the hopper 603 evenly sprinkles the hot water onto the packing 605 of the collection box 404 for mechanical energy heat exchange. The water after heat exchange passes through the filter plate 406 and enters the bottom of the collection box 404, and is discharged through the valve drain pipe. The water vapor generated by heat exchange rises and is absorbed by the water collector 604, and then absorbed and filtered by the activated carbon plate 409 before being discharged from the device, thus achieving the purpose of easy water collection and demisting. The outer surface of the movable disc 412 is provided with a pull rod, which can drive the movable disc 412 to rotate along the outer surface of the limiting rod 411. Then, by rotating, the first through hole provided inside the movable disc 412 and the fixed disc 410 can be adjusted or misaligned, thereby controlling the discharge volume.

[0030] Specifically, such as Figure 2 and Figure 4 As shown, when the packing 605 needs to be replaced, the control fixing structure 5 cancels the fixing of the attached collection box 404, and the two arc-shaped clamps 506 are lowered to the lowest position. The collection box 404 is then moved downward appropriately by the telescopic rod 402, thereby separating the sealing ring 405 from the sealing groove. Then, the rotating plate 401 is rotated to drive another collection box 404 to rotate directly below the cooling tower body 3, and it is driven to rise by the telescopic rod 402. It is then fixed by the fixing structure 5 in the same way, thereby reducing the size and time of the device and facilitating the replacement of the used packing 605.

[0031] Specifically, such as Figure 3As shown, both the first motor 501 and the second motor 601 are forward and reverse motors. A forward and reverse motor is a motor that can achieve forward and reverse rotation. The working principle of a forward and reverse motor is based on changing the phase sequence of the motor's power supply to change the direction of rotation. In a three-phase asynchronous motor, the direction of rotation of the motor can be changed by swapping any two phases. This operation is called commutation, which allows the motor to run in different directions as needed.

[0032] Specifically, such as Figure 2 As shown, the main components of the electric slide rail 505 include a power supply, a motor, a driver, a controller, a transmission mechanism, and the slide rail itself, which consists of a track and sliding blocks. Its working principle is as follows: the power supply provides electrical energy to the entire system; the motor, as the power source, is driven to rotate by the driver under the command of the controller; and the transmission mechanism is responsible for converting the rotational motion of the motor into the linear motion of the sliding blocks on the slide rail. Common transmission mechanisms include precision mechanical structures such as worm gears, lead screws, and nuts. During operation, the controller precisely controls the motor's speed, direction, and working time according to a preset program or external signals, thereby driving the sliding blocks to slide smoothly and accurately on the track. This motion method has high precision and stability, meeting the linear motion requirements of various automated equipment and precision machinery. Furthermore, the electric slide rail 505 is equipped with limit devices and safety protection devices to ensure that the sliding blocks move within a specified range and can quickly stop movement in case of abnormal conditions, thus protecting the safety of equipment and operators. At the same time, the maintenance and upkeep of the electric slide rail 505 are relatively simple; only regular inspection and lubrication are needed to ensure its long-term stable operation.

[0033] Specifically, such as Figure 1 As shown, the control panel is electrically connected to all the electrical equipment within the device. The control panel sends control commands to each component via control signal lines. These signal lines can be analog signal lines, such as 4-20mA current signals, digital signal lines, such as RS485 communication interfaces, or simple switch signal lines. The control signals sent by the control panel are transmitted to the control units of each component via the signal lines. The start and stop operations of each component can be realized through the buttons or touch screen interface on the control panel. After receiving a start command, the controller will send corresponding control signals to each component to start them. When a stop command is received, a stop signal is sent to stop each component from working. The operating parameters of each component can be set on the control panel interface. These parameter settings will be converted into corresponding control signals and sent to the control units of each component, thereby realizing precise adjustment of the operating status of the components. The control panel has the function of monitoring the operating status of each component and can display the operating parameters and status information of each component in real time.

[0034] In summary, this open cooling tower water collection and defogging device delivers hot water into the cooling tower body 3 through the inlet pipe, cools the hot water through the cooling structure 6, and then collects and discharges the liquid inside the device through the water collection and defogging structure 4, preventing the formation of white mist and creating a high-humidity environment in the surrounding area. Furthermore, the fixing structure 5 facilitates the replacement of the collection box 404, reducing the downtime for replacing the packing 605 and making it easier to replace the packing 605.
