Embodiment Construction

[0012] like figure 1 The flow chart of the air-inducing and concentrating siphon discharge device in the rain area of ​​the natural ventilation cooling tower is shown. Leaf 6, air induction plate 7, hydraulic self-balancing pipe collection network 8, siphon pool 9, siphon pipe 10, hydraulic user 11, drain pipe 12, pool 13, circulating water pump inlet pipe 17, circulating water pump 14, circulating cooling water supply pipe 18 , Cooler 15, circulating cooling water inlet pipe 16, the special device that siphon replenishment valve 19 forms.

[0013] The showering water under the natural ventilation cooling tower 1 forms the rain area 2, and the concentrator 3 collects the raining water in the rain area 2 and sends the collected shower water to the conical frustum connector 4 and the vortex elimination connector 5, and the conical frustum connector 4. The bottom of the vortex elimination connector 5 is connected to the hydraulic self-balancing pipe collection network 8, and the...

Abstract

The invention relates to an air induction flow gathering siphon discharging device for a rain belt of a natural venting cooling tower. Part of drenching water under the natural venting cooling tower is collected by a flow gathering device, the drenching water collected into the flow gathering device is fed into a frustum communicator and vortex eliminating communicators which are connected with the flow gathering device; the bottoms of the frustum communicator and the vortex eliminating communicators are connected with a hydraulic self-balance pipe collection network; outlet pipes of the hydraulic self-balance pipe collection network are connected with a siphon pool which directly supplies water for hydraulic users; drain water of the hydraulic users is returned back to a water pool by drain pipes; water in the water pool is fed into a circulation pump for boosting by a water inlet pipe of the circulation water pump; outlet water of the circulation water pump is fed into a cooler by a circulation cooling water supply pipe; outlet water of the cooler is fed into the natural venting cooling tower by a circulation cooling water inlet pipe; the frustum communicator is provided with a guide fan blade; the vortex eliminating communicators are provided with adjustable air induction guide plates. The natural venting cooling tower is subjected to air distributing optimization, the temperature of circulation water is reduced, waterhead of part of drenching water is used, effects are increased, energy is saved and the operation economy of a cold end system is improved.

Description

technical field [0001] The invention relates to one, in particular to a siphon discharge device for introducing wind and concentrating flow in the rain zone of a natural ventilation cooling tower. Background technique [0002] The "Twelfth Five-Year Plan" energy plan puts forward two binding goals of energy saving and emission reduction for my country's power industry, and it is becoming more and more difficult for thermal power units to further save energy and reduce emissions. As an important auxiliary equipment in a power plant, the natural draft cooling tower still has room for further optimization in terms of air distribution optimization and tail water surplus pressure utilization of circulating cooling water. [0003] Generally, a unit unit is equipped with a cooling tower. Taking a 600MW thermal power generation unit as an example, the circulating cooling water of the cooling tower is about 20-30m 3 / s, if 5% of the rain area of ​​the natural ventilation cooling tow...
