Description

Counter-flow type ventilation cooling tower

Technical Field

The utility model relates to an industry cooling decoration equipment field, specific reverse flow type ventilation cooling tower that says so.

Background

The cooling tower is mainly applied to the fields of air conditioner cooling systems, refrigeration series, injection molding, leather making, foaming, power generation, steam turbines, aluminum profile processing, air compressors, industrial water cooling and the like. The water moves downward as the air in the counter-flow cooling tower passes upward through the fill. As the cross-flow cooling tower air moves horizontally through the fill, the water moves downward.

The cooling tower is a heat sink, so that the water to be cooled is cooled in the tower mainly by means of the evaporative cooling effect of the water. In order to fully utilize water resources, the load of a production line fresh water supply pipe network and reduce the operation cost, cooling water for a condenser of a thermal power plant is treated by a cooling tower and recycled.

The cooling tower utilizes a natural ventilation or mechanical ventilation method to cool the sprayed hot water. Cooling towers are widely used in cooling systems of thermal power plants. The temperature of water is increased after heat exchange in a condenser and other heat exchange equipment, hot water is pumped to the top of a cooling tower by a water pump, the hot water is uniformly sprayed to a packing layer by a nozzle to be contacted with air flowing from bottom to top, the temperature of the water is reduced, the water is required to be uniformly sprayed on the packing layer, or a uniform water film is formed on the surface of the packing layer, so that the contact surface of the water and the air is increased, the contact time is prolonged, and good conditions are created for mass transfer and heat transfer in the cooling tower.

After the air is mass-transferred and heat-transferred, its temp. is raised, water content is increased, and when the tower top is close to saturation state, it is discharged into atmosphere. As a result, part of the water is evaporated, absorbing the latent heat of vaporization, lowering the temperature, and at the same time, the air comes into contact with the water, cooling the water, both of which lower the circulating water temperature.

The cooled water flows into a water collecting tank, then flows into a cold water well and is pumped into a condenser and other heat exchange equipment by a pump to be washed to form a circulating water system.

The louver at the bottom of the existing cooling tower has larger ventilation resistance, and the phenomenon of splashing is more serious due to larger fall after the top drenched water flows down, so that the water resource waste also has larger influence on the surrounding environment of the cooling tower.
