Abstract

The invention provides a ventilation well water-avoiding flow guide device suitable for an eight-height tower. The ventilation well water-avoiding flow guide device comprises a cooling tower. A waterdistribution groove, a plurality of spray devices and a water collecting tank are arranged in the cooling tower. A flow guide slope is obliquely arranged in the middle position in the cooling tower. Aplurality of cold water ports are formed in the surface of the flow guide slope. Ventilation wells are correspondingly embedded in the cold water ports. Flow guide structures are mounted in the ventilation wells. Conical flow guide grooves are correspondingly formed in the upper end and the lower end of each flow guide structure. The small ends of the flow guide grooves are communicated through flow guide holes, and the large ends of the flow guide grooves face outwards. A fairing is fixed to the upper ends of the ventilation wells through a plurality of groups of stainless steel supports ina threaded manner, the upper and lower surfaces of the fairing each are configured to be an arc-shaped spherical surface, and the arc-shaped spherical surface of the lower surface of the fairing extends to the upper portions of the flow guide grooves. The ventilation well water-avoiding flow guide device solves the problems that in the prior art, the structure is complex, the high water level causes large noise, and the cooling water is easy to blow back due to the reverse air flow and achieves the effects that the high-position tower does not leak water, the noise reduction effect is better,and more energy is saved.

Description

technical field [0001] The invention belongs to the technical field of cooling tower equipment, and in particular relates to a water-shielding diversion device and a diversion method for a ventilation shaft suitable for an eight-high tower. Background technique [0002] In order to achieve the purpose of saving energy and improving the environment, it is widely used in wet counterflow natural ventilation cooling towers in the circulating water system of steam turbine generator sets in industries such as thermal power generation. After a long period of conventional structure use, a major revolutionary innovation has finally ushered in - the high-level water collection cooling tower. Conventional wet-type counter-flow natural ventilation cooling towers that have been used in history are equipped with a sump below the water-sprinkling fill. The cooled circulating water falls into the sump from the bottom of the fill, and the pressure of the return water disappears completely, a...
