Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a device for online cleaning of cooling tower fillers. Background Art

[0002] The cooling water pump lifts the cooling water heat-exchanged by the refrigeration unit to the top of the open cooling tower, and then sprays it on the filler. Air passes through the filler area, and by the direct contact of water and air, the water is evaporated. The evaporated water vapor is taken away and discharged into the atmosphere. The cooled water flows back from the water outlet at the bottom of the cooling tower to the chiller for recycling.

[0003] The filler is the most important part of the cooling tower. However, during the long-term use of the open cooling tower, scale and dust are inevitably formed inside the filler. Manual cleaning of the filler is often time-consuming and laborious, with high energy consumption, and the cooling tower needs to stop running during the filler cleaning.

[0004] To solve the above problems, a device for online cleaning of cooling tower fillers needs to be designed. This device utilizes the mechanical principles of torque and centrifugal force. The cooling tower fan provides torque. Two vertical risers, the cooling tower water collecting tray, a submersible pump, a filter, a dosing device, a vibrator, etc. form a small water circulation system inside the cooling tower. The scale inside the filler is softened by the agent, and the vibrator strengthens the filter to remove the scale. While ensuring the normal operation of the cooling tower, the filler of the cooling tower is cleaned, making the filler cleaning become a daily maintenance task. Summary of the Utility Model

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Refer to Figure 1, an embodiment provided by the utility model: a device for online cleaning of cooling tower packing, including a cooling tower 9, a base platform 3 is fixedly connected inside the cooling tower 9, an eccentric riser 1 is rotatably connected at a position offset from the center at the top of the base platform 3, a plurality of spray nozzles are fixedly connected at equal intervals on one side of the outer wall of the eccentric riser 1, a central riser 2 is fixedly connected inside the cooling tower 9, a water collecting tray 12 is fixedly connected at the bottom of the cooling tower 9, a submersible pump 5 is fixedly connected at the bottom of the water collecting tray 12, the water collecting tray 12 is communicated with a filter 4, a dosing device 6 and a control device 7, vibrators 8 are fixedly connected to both the bottom and the side of the cooling tower 9, a blind plate one 1-2 is fixedly connected at the top of the eccentric riser 1, a rotating shaft one 1-1 is rotatably connected at the top of the blind plate one 1-2, a fan 10 is fixedly connected at the top of the rotating shaft one 1-1, a rolling connector 1-3 is rotatably connected to the outer wall of the central riser 2, and the rolling connector 1-3 is fixedly connected to the right side of the eccentric riser 1. A water inlet pipe 4-1 is communicated at the bottom of the water collecting tray 12, the bottom end of the water inlet pipe 4-1 is communicated with the filter 4, the right side of the filter 4 is communicated with a water outlet pipe 4-2, one end of the water outlet pipe 4-2 is communicated with the suction port of the submersible pump 5, the dosing pipe of the dosing device 6 is connected to the right side of the water outlet pipe 4-2, the left end of the water outlet pipe 4-2 is connected with the filter 4, a blind plate two 1-4 is fixedly connected at the bottom of the eccentric riser 1, a rotating shaft two 1-5 is rotatably connected to the blind plate two 1-4, and a rolling member 1-6 is rollingly connected at the bottom of the rotating shaft two 1-5, and the rolling member 1-6 is rollingly connected to a movement groove at the top of the base platform 3;

[0029] Specifically, by operating the control device 7 to start the submersible pump 5, the filter 4 is filtered accordingly. At the same time, the dosing device 6 injects the medicament into the water outlet pipe 4-2. Subsequently, the cooling water containing the medicament is transported to the eccentric riser 1 through the central riser 2. At the same time, the rotational force of the fan 10 drives the eccentric riser 1 to rotate. During this process, the rotating shaft two 1-5 rotates around the central riser 2 at the top of the base platform 3, promoting the medicament to be evenly sprayed into the interior of the packing 11, softening and removing the scale adhering to its surface. In addition, by starting the vibrator 8, the scale falling-off effect can be further enhanced, enabling the scale to dissolve in the cooling water, thereby facilitating the subsequent effective removal through the filter 4.

[0030] Refer to Figure 1 , the control device 7 is electrically connected to the submersible pump 5, the dosing device 6 and the vibrator 8 respectively. A packing 11 is fixedly connected inside the cooling tower 9. Vibrators 8 are fixedly connected to the bottom and the right side of the cooling tower 9. A fan 10 is rotatably connected to the top of the cooling tower 9. A packing 11 is fixedly connected inside the cooling tower 9. A water collecting tray 12 is fixedly connected at the bottom of the cooling tower 9. An inlet 13 is provided at the top of the cooling tower 9. An outlet 14 is provided at the middle and lower part on the right side of the cooling tower 9;

[0031] Specifically, the control device 7 can freely control the operation of the submersible pump 5, the chemical dosing device 6, and the vibrator 8. The fan 10 drives the eccentric riser 1 to rotate for spraying the chemical agent. The water inlet 13 facilitates water intake, and the water outlet 14 drains water from the cooling tower 9.

[0032] Working principle: When the cooling tower packing needs to be cleaned, the control device 7 is used to operate the submersible pump 5 at this time, so that the filter 4 conducts filtration. At the same time, the chemical dosing device 6 inputs the chemical agent into the outlet pipe 4-2. At this time, the cooling water mixed with the chemical agent is transmitted from the central riser 2 into the eccentric riser 1. At the same time, the fan 10 rotates to drive the eccentric riser 1 to rotate. At this time, the second rotating shaft 1-5 rotates around the central riser 2 on the top of the base platform 3, and sprays the chemical agent into the interior of the packing 11 to soften the scale on the packing 11. At this time, starting the vibrator 8 can strengthen the scale shedding, so that the scale dissolves in the cooling water and is discharged through the filter 4.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
