Description

Counter Flow type induced draft cooling tower to reduce plume and ice generation

The present invention relates to a cooling tower.

Cooling tower is to cool water to reuse cooling water, and it uses a method of lowering the temperature of cooling water by releasing heat to the atmosphere by transferring latent heat by evaporation of water and sensible heat by contact between water and the atmosphere.

Counter flow cooling tower (Counter Flow Cooling tower) is a type of cooling tower in which the contact of water and air is in counterflow contact inside the cooling tower. There are two types: a focused draft cooling tower with a fan installed at the bottom to blow air, and an induced draft cooling tower with a fan installed at the top to suck air. have.

White smoke does not occur in the summer, when the air exchanged with the cooling water in the cooling tower becomes unsaturated by mixing with the air with high temperature and humidity. However, in the process of contacting the cold air with the moist air discharged from the cooling tower, it becomes supersaturated and becomes water droplets (water vapor). Condensation) occurs well in winter or on high humidity days in the changing seasons.

Ice and icicles generated at the inlet side of the outside air inside the cooling tower in winter and under the filler block the air inlet to the cooling tower and decrease the cooling tower efficiency, and when the temperature rises, the icicles melt and fall, damaging internal parts or causing personal injury. There is a problem with making

In addition, white lead is not a harmful substance because it is water vapor, but there is a problem that it is mistaken for smoke caused by a fire or causes civil complaints due to obstruction of view.

In order to solve this problem, as a method for reducing white smoke, the wet air heat-exchanged from the filling is heated and discharged using the heat of the cooling water, and the heated outside air is heated by using the heat of the cooling water to mix and discharged the heated outside air and the wet air that has been heat-exchanged from the filling. There is a method of heat-exchanging the wet air passing through the filling material with the incoming outside air without using the heat of cooling water, heating the outside air and condensing the wet air, mixing it inside the cooling tower and discharging it.

However, this method uses the heat of the cooling water flowing into the cooling tower, but the cooling water temperature is low, so there are disadvantages in that the white smoke reduction efficiency is low and the heat exchanger becomes large.
