Technical Field
The utility model relates to a cooling tower water conservation technical field especially relates to a mechanical draft cooling tower evaporating water recovery system.
Background
The cooling tower is a key device for industrial water, is widely applied to high-water-consumption industries such as electric power, steel, petrochemical industry and the like, and the water loss of the cooling tower accounts for 70 percent of the industrial water consumption. The mechanical ventilation cooling tower evaporated water recovery system is characterized in that an air blower pumps/blows ambient air into a cooling tower, the cooling tower is contacted with a circulating cooling tower carrying industrial waste heat in a water spraying filler area, and the waste heat of the circulating cooling water is dissipated to the atmosphere through circulating water evaporation and heat transfer. After the air is subjected to the water spraying filling, the air is changed into damp and hot air with the damp and hot close to saturation, the damp and hot air contains evaporated water, the water consumption of the cooling tower is about 90%, and if part of the evaporated water can be recycled, the water saving potential is huge.

A fan is arranged at the air outlet cylinder, and the fan is started to suck the damp and hot air containing the evaporated water in the cooling tower to the direction of the air outlet cylinder; when the fan starts, can also be through being located the air pipe device in the dryer with the automatic air-out section of thick bamboo that inhales of external environment cold air, cold air and hot-air mix in fan blade top, condense into the water droplet, the water droplet continues to rise under the drive of air current, when receiving the water installation through static, the water droplet is caught and is collected to can reach the moisture content of retrieving the evaporation in the air.
The working principle of the electrostatic water collecting device is as follows: the charges are divided into positive charges and negative charges, and the acting force between the charges can be classified into 'like charges repel each other and opposite charges attract each other'. In the molecules of an object, the electron-binding capacities of different atoms are different, so that a positive center and a negative center are formed in the whole molecule due to the different electric properties of the atoms. The positive and negative electric centers are coincident and are called nonpolar molecules; conversely, molecules with non-coincident positive and negative electrical centers are referred to as polar molecules. The water molecule is a polar molecule. When water molecules are acted by an external electric field, the water molecules move to the polar plate to be collected, and the water collecting effect is achieved after the water molecules are collected.
