The closed-circuit cooling tower manufacturer talks about the ways we want to assemble the closed-circuit cooling tower.

Jiangsu Yunuo Cooling Technology will introduce the closed cooling tower manufacturers and talk about how we want to assemble the closed cooling tower.

The closed cooling tower originated from the evaporative cooler, which began in the middle of the last century, and gradually began to be used with the development of the chemical, metallurgical, and electronic industries. Regarding evaporative cooling technology, as early as 250 BC, the ancient Egyptians already knew how to use water evaporation for cooling. In the last century, various countries have also conducted many studies on evaporative cooling technology. In the 1970s, the emergence of the energy crisis made the use of evaporative cooling technology gradually paid attention. In the 1980s, when it was discovered that the catastrophic climate that poses a huge threat to human livelihoods is related to the air-conditioning and refrigeration industry, passive cooling technologies such as evaporative cooling technology that utilize natural conditions to obtain cooling capacity have been rapidly developed. The American ASHRAE has established a technical committee called "evaporative cooling", which aims to promote the use of evaporative cooling technology, collect and publish data on the use, installation, operation and protection of evaporative cooling systems, publish specifications, standards, and reward and reward Research on evaporative cooling, in order to promote the use of evaporative cooling equipment in the whole world.

When the outside temperature is low, the water spray system can be stopped to save water. Pushing the implementation of energy conservation and emission reduction policies and the increasing scarcity of water resources, closed cooling towers have been widely used in metallurgy, aviation, electric power, chemical industry, machinery, petroleum, food, plastics, rubber and other industries in recent years. After the circulating water evaporates, the dissolved substances in the water will be left, which will increase the water concentration. After the water is concentrated, corrosive addition and scale will be added, which will reduce the cooling tower capacity and damage the piping and equipment. In order to avoid this situation, it is recommended to use the method of releasing part of the circulating water. In order to avoid freezing of the copper pipe (radiator) and distribution water of the closed cooling tower, please pay attention to these points. In order to avoid freezing of the circulating water, Please add antifreeze in circulating water, or add antifreeze electric heater in piping. After adding antifreeze, the freezing temperature drops, and it is not easy to freeze.

The closed cooling tower manufacturers then pass the forced convection of the spray water and the air to the air, and the heat transfer of the spray water to the air reduces the energy consumption; the two-layer cooling method of air-cooled evaporation absorbs heat, and the cooling efficiency is high; it can be directly Cooling water, oil, alcohol, quenching liquid, brine and chemical liquid and other media, the medium has no loss, and the composition is stable due to the use of closed circulation. The medium is not affected by the environment and will not pollute the environment. It is mainly composed of the latent heat of the spray water evaporation and the sensible heat exchange between the spray water and the air. Because the cooled fluid is completely closed between the cooling tower and the process equipment. , Therefore, there is no phenomenon that debris enters the cooling pipeline system, and then the pipeline is blocked; the soft water is circulated for cooling. There is never scale formation at high temperature, which causes scaling of the cooling pipeline system. It is different from the general cooling tower where the cooling fluid directly touches the air, so it is called a closed-circuit tower. The closed cooling tower of the cooling tower manufacturer has a fully closed circulation cooling, which occupies a small area, does not need to excavate a pool, is easy to locate, and saves water.
