Technical Field

The invention relates to the technical field of cooling heat dissipation towers, in particular to a two-stage evaporative cooling heat dissipation tower.

Background

The cooling tower is generally adopted by a traditional heat dissipation tower for an air conditioner, and the cooling tower is divided into two forms: cross flow towers and counter flow towers. The cross flow tower is characterized in that the filler is vertically arranged at the air inlet side of the tower body, water flows are sprayed on the filler, and air flows are vertical to the water flow direction. The countercurrent tower is characterized in that the filler is horizontally placed, water flows on the filler, the direction of air flow is opposite to that of the water flow, the principle of the countercurrent tower is direct evaporation cooling, moisture is taken away by air, and water vapor is changed from a liquid state to a gaseous state to absorb heat, so that the heat of the water is taken away by means of moisture evaporation, and the temperature of the water is reduced.

a the lowest approximation degree of the outlet water temperature and the wet bulb temperature of the traditional cooling tower is 3 ℃, if the outlet water temperature of the cooling water needs to be further reduced, the volume of the cooling tower needs to be increased, the filler area is increased, the price is greatly increased, the outlet water temperature of the cooling water cannot be greatly reduced, the approximation degree can only be close to 2.5 ℃, and the wet bulb temperature cannot be reached ever.

In the air-conditioning refrigeration system, the relation between the condensation temperature and the refrigeration efficiency of the water-cooling chiller is that the refrigeration efficiency is improved by 2 to 3 percent when the condensation temperature is reduced by 1 ℃, so that the reduction of the condensation temperature is an important technical direction for saving energy of the air-conditioning chiller. However, the characteristics of the cooling tower determine that the outlet water temperature is limited by the outdoor wet bulb temperature, so that the cooling tower is not feasible to prepare cooling water with the temperature lower than or equal to the wet bulb temperature.
