Description

Technical Field

[0001] The present application relates to the field of cooling towers, and in particular to an EC fan exhaust open cross-flow cooling tower. Background Art

[0002] With the rapid development of industry and urbanization in my country, the environmental requirements and energy use standards are getting higher and higher, which brings great challenges to the technology of various industries. The use of various types of cooling towers and cooling technologies is a development direction for achieving water conservation, emission reduction, noise reduction and environmental protection. A cross-flow cooling tower is a cooling tower in which water flows vertically from the top of the tower, and air flows horizontally through the water-spraying filler. The airflow and water flow are orthogonal to each other. Water exchanges heat and mass with the air passing through it, causing the water temperature to drop.

[0003] The patent document with the announcement number CN 211823920 U discloses an EC fan exhaust open cross-flow cooling tower, including a base, a tower body welded on the outer wall at the top of the base, and a through hole is opened at the center of the outer wall at the top of the tower body, four EC axial flow fans are installed inside the through hole by bolts, and filters are welded on the outer wall at the top of the EC axial flow fans, installation grooves are opened on the outer walls on both sides of the top of the tower body, and a water distribution box is installed on the inner wall of the installation groove by bolts, and installation threaded holes with equidistant structure distribution are opened on the outer wall at the bottom of the water distribution box. In the utility model, the EC axial flow fan is arranged on the top of the tower body, and the EC axial flow fan introduces the air outside the tower body into the tower.

[0045] Specifically, two transmission rods 31 are rotatably connected on both sides of the interior of the box body 2, and the transmission rod 31 is fixedly connected to one of the three rotating rods 21, and one side of the two transmission rods 31 is fixedly connected to a first pulley 32, and one side of the two first pulleys 32 is meshed with the same first belt 33.

[0049] The implementation principle of an EC fan exhaust open cross-flow cooling tower in the embodiment of the present application is as follows: first, when the device is in operation, hot water enters the water tank 14 through the water inlet pipe 13, and then the hot water flows into the liquid separation box 27 through the water outlet pipe 28 at the bottom of the water tank 14. When the hot water enters the water tank 14, the fan blades 16 drive the rotating shaft 15 on one side through the bevel gear 22 to drive the rotating rod 21 to rotate.

When the rotating shaft 15 drives the bevel gear to rotate, the second pulley 18 and the second belt 19 are also used to drive the blowing fan 20 on the transmission shaft 17 to rotate, so that it and the EC flow fan both guide the dry cold air into the device. The dry cold air flows into the device and becomes humid hot air after passing through the heat exchanger 8. When the dry cold air passes through the heat exchanger 8, it will exchange heat with the water film on the heat exchange filler, cool the hot water and become humid hot air to leave the heat exchanger 8. The cooled water is collected in the drain pipe 4 inside the bottom box 1 through the heat exchanger 8, and its discharge is controlled by the valve 5. The humid hot air coming out of the heat exchanger is drawn out of the device through the air outlet of the EC axial flow fan 10 to complete the cold and heat exchange.
