Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a water-saving cooling tower capable of collecting cooling water. Background Art

[0002] Circulating cooling water is a critical cooling medium in industries like chemical and metallurgy, and is required in a wide range of heat exchange equipment. After absorbing heat, the circulating cooling water rises in temperature, becoming known as circulating cooling return water. This water needs to be cooled before being recycled. A cooling tower cools the circulating cooling return water by creating countercurrent contact between air and the water.

[0003] The existing Chinese utility model patent with reference publication number CN214842589U discloses a water-saving cooling tower. The utility model includes a cooling tower body and a water tank arranged below the cooling tower body, wherein the cooling tower body is provided with an air inlet and an air outlet, the air inlet is fixedly connected to an air inlet mesh, the air outlet is provided with specialized fins, a small-capacity water storage box is fixedly connected to one side of the cooling tower body, the small-capacity water storage box is provided with a controller, the small-capacity water storage box is provided with a spray device for cleaning the air inlet mesh, and the small-capacity water storage box is fixedly connected to a device water supply pipe used in conjunction with the water tank. During use of the cooling tower, the specialized fins at the air outlet enable the cooling tower to have a certain ability to recycle water. The recycled water is stored in the small-capacity water storage box outside the tower through the device water inlet pipe located outside the tower, thereby preventing water vapor in the cooling tower body from being discharged through the air outlet, reducing water loss in the tower, and thus reducing cooling costs.

[0004] Existing cooling towers generally use spraying to allow the filler to absorb a certain amount of water. During use, due to the vertical upward direction of the airflow inside the cooling tower, some cooling water will be discharged from the top of the cooling tower under the drive of the airflow. At the same time, a water pan is provided at the bottom of the existing cooling tower. The dust captured by the cooling water will be collected by the water pan together with the cooling water. The dust will settle at the bottom of the water pan, which is very inconvenient to clean. Utility Model Content
