Cross-flow open-close type cooling tower

Abstract

The invention discloses a cross-flow opening and closing type cooling tower, and belongs to the technical field of cooling towers. Comprising a tower body, a water inlet pipe, a water collecting basin, at least two dividing wall type heat exchangers, at least two water distribution structures and an air draft structure, the at least two dividing wall type heat exchangers are arranged at the top of the water collecting basin, and a mixing interval is arranged between the two dividing wall type heat exchangers; the air inlet part and the air outlet part are each provided with a plurality of vertically-arranged wet area channels and a plurality of obliquely-arranged dry area channels. The wet area channels and the dry area channels are alternately arranged; the end, close to the filler main body structure, of the dry area channel communicates with the filler main body structure, and an air inlet is formed in the end, away from the filler main body structure, of the dry area channel; the lower end of the wet area channel is communicated with the mixing area; according to the invention, white fog can be reduced, the water vapor content of air is reduced, water loss is avoided, resources are saved, and the operation mode is simple.

Description

technical field [0001] The invention relates to the technical field of cooling towers, in particular to a cross-flow opening and closing cooling tower. Background technique [0002] A traditional cooling tower generally includes a tower body, an exhaust device, a packing layer installed in the tower body, and a spray device. When in use, the hot water sprayed by the spraying device sprays into the packing layer from top to bottom, and the dry and cold air from the outside enters the packing from bottom to top, and the hot water and cold air exchange heat in the packing layer, so that the hot water The temperature is cooled down, while the air is heated and humidified, and the high-temperature and high-humidity air is discharged from the tower through the air outlet. However, in winter, due to the high water vapor content of the high-temperature and high-humidity air, it is cooled by the external cold air when it is discharged out of the tower, and condenses to produce a lot...

AI Technical Summary

Problems solved by technology

[0004] (1) The water vapor content of the discharged air is relatively high, causing a large amount of water to be lost by evaporation;

[0005] (2) White mist is generated, causing the road surface around the cooling tower to be wet and slippery, which affects the normal inspection of the staff;

[0006] (3) There are two modes of operation: normal operation mode and anti-fog mode, and the operation mode is complicated
