Description

A cooling tower with water-saving function

technical field

The utility model relates to a cooling tower, in particular to a cooling tower with a water-saving function. the

Background technique

The cooling tower is an important heat and mass transfer equipment in the energy and chemical industries, and it is an important device to complete the cooling of circulating water. In the natural ventilation cooling tower, the circulating cooling water exchanges heat with the air in the tower through evaporation and heat transfer. In the two methods, the latent heat transfer of evaporation occupies most of the heat transfer, so the saturated humid air discharged outside the tower contains a large amount of water vapor, so the evaporation loss is the largest loss. In addition, the saturated humid air contains tiny water droplets, which part of the water droplets It has almost no effect on heat dissipation, which is called wind blowing loss, which can be avoided as much as possible. Another kind of loss is sewage loss. Determined by the concentration ratio. The cooling towers in the prior art have the following defects: ① Conventional cooling towers basically cannot avoid evaporation loss, which is a necessary condition for heat exchange and cooling. If there is no water collector or the effect of the water collector is not good, wind loss is also inevitable. ②The high-voltage electrostatic water collection device can reduce the wind blowing loss very well, but it can't do anything about the evaporation loss, and the device needs to consume a lot of electric energy, the operating cost is quite considerable, and the water saving benefit is not enough to offset the input cost. ③Arranging a diffuser in the tower, spraying dry ice and liquid ammonia as a condensing agent method is unrealistic due to the large cost and impact on the flow field. Heat pipe technology is used in cooling towers to save water. The engineering feasibility of this technology is limited due to expensive heat pipes, complicated injection devices and high-altitude arrangement of condensed water recovery devices.
