Wet cooling tower

Abstract

The invention relates to the technical field of cooling towers, in particular to a wet-type cooling tower which comprises a tower body, a filler layer, a spraying device and a water collector are sequentially arranged in the tower body from bottom to top, an air inlet is formed in the tower wall below the filler layer, an air outlet is formed in the top of the tower body, a fan is arranged at the air outlet and arranged in an air duct, and the water collector is arranged in the air duct. An electrothermal film is arranged above the water collector and is used for demisting; the fog dispersal device is simple in structural design, small in occupied space, low in energy consumption, high in fog dispersal efficiency and long in service life.

Description

technical field [0001] The invention relates to the technical field of cooling towers, in particular to a wet cooling tower. Background technique [0002] The cooling tower is a device that uses water as a circulating coolant to absorb heat from the system and discharge it to the atmosphere to reduce the water temperature; it uses water and air to exchange heat and cold to generate steam, and the steam volatilizes to take away heat to achieve evaporation and heat dissipation. The principle of convective heat transfer and radiation heat transfer is used to dissipate the waste heat generated in industry or in refrigeration and air conditioning to reduce the water temperature of the evaporative cooling device to ensure the normal operation of the system. Cooling towers are divided into wet cooling towers, dry cooling towers and wet and dry cooling towers according to the contact mode of water and air. [0003] When the temperature is low in winter, the water vapor discharged f...

AI Technical Summary

Problems solved by technology

However, there are certain defects in both technologies. The fin tube type defogging has higher requirements on the space height of the cooling tower, and the water pump head needs to be increased, which increases the energy consumption of the cooling tower. The defogging process is more complicated, and the louver system and Vacuum pumping system; the surface of finned tubes is easy to collect dust, which affects the heat transfer effect and needs to be cleaned regularly; it is only suitable for new projects and cannot be modified for the original cooling tower

Condensing modular defogging has certain requirements on the height of the air chamber, and a certain pump head needs to be increased. Its biggest disadvantage is that the resistance is relatively large, especially in summer when the defogging is not used. The resistance will increase the energy consumption of the cooling tower, thereby increasing the cooling capacity. The long-term operation cost of the tower; the fog elimination process is relatively complicated, and the shutters on the outer wall and the flap system at the lower part of the module need to be adjusted; it is only suitable for new projects, and cannot be modified for the original cooling tower
