Problems solved by technology

[0003] However, the existing counterflow cooling towers only pay attention to the research on the local structure of the cooling tower, and there is little research on the overall ventilation structure of the cooling tower. Therefore, the cooling effect of the existing counterflow cooling tower needs to be improved

Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0026] Example.

[0027] A kind of countercurrent cooling tower in the present embodiment, as figure 1 Shown, comprise tower body frame 1, be located at the air duct 2 on the top of tower body frame 1, as Figure 4 As shown, the air cylinder surface near the air outlet 22 of the air cylinder 2 is a shrinking curved surface 21, so that the flow field converges toward the middle. Such as figure 1 As shown, the fan 9 is arranged in the fan tube 2 and the air outlet 22 of the fan tube 2 is facing downward, so that the blowing of the fan is downward, and then the hot water is cooled. The bottom of the air outlet 22 of the air cylinder 2 is provided with a water eliminator 3, a spray pipe 4, a filler 5 and a pool 6 in sequence, so that the hot water enters the pool 6 after being cooled successively, and the pool 6 is a concrete pool in addition. Th...

Abstract

The invention relates to the technical field of cooling towers, in particular to a reverse flow cooling tower. The reverse flow cooling tower comprises a tower body frame and a wind cylinder arrangedat the top of the tower body frame, and the wind cylinder face, close to a wind outlet of the wind cylinder, of the wind cylinder is a shrinking hook surface; the wind cylinder is internally providedwith a fan, the wind outlet of the wind cylinder faces downwards, and a water collector, a spray pipe, a filler and a water pool are sequentially arranged below the wind outlet of the wind cylinder; and an opening of the water collector is open towards the wind outlet of the wind cylinder, the spray pipe is connected with the water collector, a nozzle of the spray pipe faces the filler, the bottomface of the filler is led to the water pool, and the filler is a wooden inserting-piece type filler. The reverse flow cooling tower has the advantages that wind resistance is small, the flowing-around performance is good, and the cooling efficiency is high.

Description

technical field [0001] The invention relates to the technical field of cooling towers, in particular to a counterflow cooling tower. Background technique [0002] Cooling towers are the most important equipment in large-scale industrial circulating water fields, and are the fundamental guarantee for industrial water recycling. At present, in the application field of industrial cooling towers in my country, there are two types of cooling towers that handle large amounts of water, namely: natural ventilation cooling towers and mechanical ventilation counterflow cooling towers, because counterflow cooling towers are suitable for papermaking systems that require large temperature differences and small approximation degrees Therefore, in the papermaking process, countercurrent cooling towers are more likely to be used to ensure papermaking recycling water. [0003] However, the existing counterflow cooling towers only pay attention to the research on the local structure of the co...
