Description

A cooling tower for printing and dyeing industry

technical field

The utility model relates to the technical field of machinery, in particular to a cooling tower for the printing and dyeing industry.

Background technique

The cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it to the atmosphere to reduce the water temperature. Its cooling is to use water and air to exchange heat and cold to generate steam. The steam evaporates and takes away the heat to achieve evaporation. The principle of heat dissipation, convective heat transfer and radiation heat transfer is used to dissipate the waste heat generated in industry or in refrigeration and air conditioning to reduce the water temperature. The evaporative cooling device is used to ensure the normal operation of the system. The device is generally barrel-shaped, so it is called a cooling tower. At present, the cooling towers used for sewage treatment in the printing and dyeing industry mostly use grid-shaped fillers. Since the printing and dyeing industry contains a large amount of impurities such as textile short fibers and cotton yarns, the fillers will generally be blocked after one year of use, affecting the normal cooling of the cooling tower. However, the cooling tower has a large volume and is time-consuming and laborious to clean. Moreover, the water in the cooling tower cannot be recycled, and part of the water is also lost in the air, which reduces the working efficiency of the cooling tower.
