Problems solved by technology

[0006] When the cooling tower in northern my country is running in winter, some parts of the cooling tower will freeze due to the low temperature, which will affect the normal operation of the cooling tower.
Icing has serious hazards, which will affect the cooling effect of the tower, increase the load of the structure, reduce the service life of the concrete structure, and cause cracking of pipeline valves, etc.
In addition, the spray water of the counterflow natural ventilation cooling tower falls directly into the pool after leaving the filler, and the falling height is large, which is the main source of noise in the cooling tower. The noise comes out from the air inlet, causing serious noise pollution to the surroundings

Embodiment Construction

[0030] According to the problems existing in the existing counterflow natural ventilation cooling tower technology, the present invention proposes a multifunctional composite air intake control device for counterflow natural ventilation cooling towers. Please refer to figure 1 with figure 2As shown, a certain number of air deflectors 2 are installed outside the herringbone pillar at the bottom of the cooling tower 1 around the cooling tower’s air intake circumference. The air deflectors 2 are vertically arranged vertically to the ground and form a The included angle α (installation angle), the degree of the included angle α is between 0 and 45 degrees. The air deflectors 2 are arranged at equal intervals along the air inlet circle at the bottom of the cooling tower 1, and their positions are set at the triangular air inlet formed between the two herringbone pillars 4, and the number of the air deflectors installed is determined according to actual needs. When there are pipel...

Abstract

The invention relates to a multifunctional compound air inlet control device of a counterflow type natural ventilation cooling tower. The multifunctional compound air inlet control device constituted by a certain number of air guide plates, air baffle plates and sound insulation plates is arranged outside the air inlet circumference of the cooling tower, wherein the multifunctional compound air inlet control device can improve air inlet uniformity of the cooling tower, improve the performances of the cooling tower, reduce the temperature of circulating water out of the tower and improve economy in operation of an unit through the air guide plates; by arranging the air baffle plates, the cooling tower can be prevented from being iced in cold winter; and by arranging the sound insulation plates, noise pollution at the periphery of the cooling tower can be further reduced.

Description

technical field [0001] The invention relates to a multifunctional composite air intake control technology of a counterflow type natural draft cooling tower. This technology sets a certain number of wind deflectors, windshields and sound insulation boards outside the cooling tower air inlet circle to form a multi-functional composite air inlet control device to control and optimize the uniformity of the air inlet flow field and the air volume into the tower. In order to realize the control of the cooling effect of the cooling tower. The invention can reduce the outlet water temperature of the cooling tower, prevent the freezing of the cooling tower, reduce the noise pollution in the area of ​​the cooling tower, and improve the economy and safety of unit operation. The invention belongs to the fields of thermal power and nuclear power. Background technique [0002] The counterflow natural draft cooling tower is a widely used cooling equipment in the power system at present. ...
