Description

Technical Field

[0001] The utility model relates to the field of air cooler flushing, and particularly to a flushing device applied to an air cooler. Background Art

[0002] A large air cooler mainly consists of components such as a tube bundle, a fan, and a bracket. The hot (gas / liquid) fluid to be cooled flows inside the tube bundle, and the outside of the tube bundle is surrounded by fins to increase the contact area between the tubes and the air, thereby improving the heat exchange efficiency. Since the vast majority of air coolers are installed outdoors, the fins for heat dissipation outside the air cooler tube bundle and the gaps between the fins are very easy to accumulate dirt. This part of the dirt adheres to the fin surface for a long time, reducing the heat exchange effect between the external cooling air and the hot fluid inside the tube bundle, resulting in a significant reduction in the heat exchange efficiency of the air cooler. The application with the publication number CN210400152U in the prior art discloses a mobile cleaning pressure-resistant trolley for air cooler maintenance, which includes wheels and a vehicle bottom plate on the wheels, and a high-pressure flushing machine and a pressure boosting device are arranged on the vehicle bottom plate.

The present utility model can complete the on-line flushing of the fins of the air-cooled tube bundle under remote control. The whole flushing process does not require on-site participation of personnel, saving labor costs and ensuring the flushing effect at the same time.

[0026] Embodiment 2: A flushing device for an air cooler, such as Figure 3 As shown, the water cannon 8 adjusts the vertical direction of the water cannon 8 through the steering motor Ⅱ15. The water cannon 8 includes a nozzle 18 and a conduit 20, and the conduit 20 is connected to the nozzle 18; the output shaft of the steering motor Ⅱ15 is connected to the reducer through a coupling, and the reducer is connected to the driving gear Ⅱ16, and the driving gear Ⅱ16 is meshed with the driven gear Ⅱ17. The driven gear Ⅱ17 is fixed at the bottom end of the nozzle 18, and a rotating shaft is provided on the driven gear Ⅱ17. The nozzle 18 rotates around the rotating shaft following the driven gear Ⅱ17; the steering motor Ⅱ15 is electrically connected to the controller.

[0027] A visual sensor 9 is provided on the nozzle 18 of the water cannon 8, and the visual sensor 9 is connected to the controller, and the controller is wirelessly connected to the display; the information is transmitted back to the monitoring computer in the control room through the network line to monitor the flushing process in real time. During the flushing process, the intermittent start and stop operation of the electric switch valve on the process production water pipeline can also be coordinated to check the effect of the tube bundle fins after flushing.

[0028] The quick connector 7 is connected to a fire hose 6, and the fire hose 6 is connected to a fixed pipeline. The fixed pipeline is provided with a switch valve, and the switch valve is electrically connected to the controller; the flushing water flow is controlled by opening and closing the switch valve; a pressure control valve is provided on the conduit 20, and a nozzle regulator 14 is provided on the nozzle 18. The pressure control valve opens when the water pressure reaches 0.6Mpa, and closes when the water pressure is less than 0.2Mpa. The water pressure is too low to achieve the flushing effect; the nozzle regulator 14 is electrically connected to the controller; the nozzle regulator 14 is controlled by the controller to achieve switching between direct current and scattered water spraying modes.

[0031] A limit sensor 10 is provided on the steering seat 1, and the limit sensor 10 is connected to the controller. When the steering seat 1 rotates and the external fire hose 6 approaches the limit sensor 10, the limit sensor 10 will feedback a signal to the controller to stop it from continuing to rotate. At the same time, the yellow "fault" signal light on the control panel lights up, and all steering adjustments fail.

[0033] The user starts the flushing program through the control panel. The controller receives the command and initializes all system components. The controller activates the drive motor, and the driving wheel 4 moves along the closed-loop arranged guide rail 3 to make the entire flushing device reach the predetermined position. The steering motors I and II respectively control the rotation of the water cannon 8 in the horizontal and vertical directions to align with the area to be cleaned of the air cooler. After the switching valve is opened, water is supplied to the water cannon 8 through the fire hose 6. The water cannon 8 adjusts its position in real time according to the preset path or through the vision sensor 9 to perform all-round flushing on the air cooler. The nozzle regulator 14 adjusts the water flow pattern as needed, such as fan-shaped spraying or linear spraying. When the flushing process is completed, the controller shuts off the water supply and stops all motors. The utility model can effectively remove dust and impurities on the air cooler, reduce the need for manual operation, and improve the cleaning efficiency. By precisely controlling the position of the water cannon 8 and the water flow parameters, the device can achieve an efficient cleaning effect on different types of coolers.
