Problems solved by technology
Due to the characteristics of the current fan and air duct structure, it is not very effective for the air duct to reduce the kinetic energy of the air discharged from the cooling tower, such as figure 1 As shown, the air flow at the outlet of the fan 2 in the cooling tower air duct 1 forms a vortex, which increases energy consumption on the one hand, and on the other hand causes the uneven distribution of the flow velocity at the outlet of the air duct to increase the kinetic energy of the outlet

Embodiment Construction
[0038] The present invention will be further described below in conjunction with the accompanying drawings.
[0039] Cooling tower energy-saving diversion air duct of the present invention, as Figure 2~Figure 9 As shown, it includes a blower shell 1 , a fan 2 and a drive motor 3 , and also includes an energy-saving deflector 4 . Wherein, the fan casing 1 is a cylindrical structure with an expansion opening at the top, and is installed on the top of the cooling tower. A blower fan 2 is installed horizontally inside the blower casing 1, and the blower fan 2 is driven by a drive motor 3 arranged outside the blower barrel. The included angle α between the two sides of the longitudinal section of the blower casing 1 and the axis is not greater than 8°, so that the airflow discharged from the blower outlet from the fan 2 will not be separated or vortexed at the side wall of the blower, so that Reduce the flow velocity at the outlet of the air duct and reduce the loss of kinetic e...

The invention discloses an energy-saving flow-guide air funnel of a cooling tower, and belongs to the industrial technical field of electric power, metallurgy and petrochemical engineering and so on. The air funnel comprises an air funnel outer shell, a fan arranged horizontally in the air funnel and a driving motor used for driving the air funnel, and further comprises an energy-saving guiding device fixedly mounted on a hub of the fan; and the energy-saving guiding device is an axial-symmetric structure with a round section, and gradually reduced section diameter from down to up. The energy-saving guiding device can be designed to different appearance structures according to different height relations between the top surface of the air funnel and the fan section. The expansion angle of the air funnel outer shell is further designed. The air funnel has the advantages of effectively conquering vortex flow at the air funnel outlet, reducing the kinetic energy at the air funnel outlet, improving the fan efficiency, reducing the fan consumption, and achieving the purpose of energy conservation.
Description
technical field [0001] The invention relates to industrial technical fields such as electric power, metallurgy, and petrochemical industry, and specifically relates to an energy-saving diversion air duct for a cooling tower. Background technique [0002] Cooling towers are mainly used in various industrial fields such as electric power, metallurgy, petrochemicals, textiles, and civil air-conditioning cooling systems, and energy consumption occupies a large proportion in industrial production. [0003] The cooling tower is the main equipment to bring the waste heat generated in industrial production to the atmosphere. The waste heat enters the cooling tower in the form of hot water, and the hot water is cooled by evaporation and conduction heat dissipation, and then returned to industrial production. To transfer the heat of hot water to the air, it is necessary to provide a large amount of fresh natural air for the cooling tower and discharge the waste heat air to the outside...
