Two Cyclic Cooling Methods of Closed Cooling Tower
In the process of industrial production, a large amount of waste heat will be generated. If the heat is allowed to cool naturally, a large amount of production time will be wasted and the production schedule will be seriously affected. If this heat is not dissipated in time, the associated equipment is damaged, resulting in an increase in production costs. Therefore, timely and rapid heat dissipation is a very important link.

The traditional open cooling system, the purchase price is low, the circulating water is sprayed on the pvc packing in the form of spray, through the contact of circulating water and air, heat exchange, and finally through the fan, the hot air after the heat exchange of water and air is taken out of the tower to achieve the purpose of cooling. In this operation process, the circulating water needs to be directly in contact with the air, which will inevitably produce a lot of impurities, and the composition of the circulating water is unstable. If it is some industries with relatively high requirements for the circulating medium, the open cooling tower cannot achieve the ideal cooling effect. In addition, the entire cycle cooling process of the open cooling system is prone to scaling, the system is easily damaged, and frequent downtime maintenance is required. The most important point is that the open cooling system requires a lot of water consumption in the process of circulating cooling, and the circulating system is easy to breed bacteria, algae, crystals, etc., which greatly increases the cost of production.
The purchase price of the closed cooling system is higher, which is about 3 times that of the open cooling tower. It is divided into two circulating cooling systems inside and outside, and these two circulating systems are completely isolated.
Internal circulation system: docking with the object equipment to form a closed circulation system, the circulating medium in the heat exchange coil closed circulation, not in contact with the outside world, the whole circulation process, the circulating medium is almost no loss, and will not produce impurities, not easy to scale. Not only save a lot of water resources, but also environmental protection and safety, no scaling, no blockage, system failure rate is very low, do not spend more money to repair and maintenance, saving expenses.
External circulation system: The external circulation system is to cool the cooling tower itself. Turn on the spray pump. The spray pump receives water from the water collection tank and sends it to the upper part of the heat exchange coil. Through the nozzle, it is evenly sprinkled on the heat exchange coil to form A thin layer of water film, the water film absorbs the heat of the circulating water in the coil, and the temperature decreases. In addition, cold air and spray water through many times of cold, hot alternate, greatly reducing the tower temperature, finally, the high temperature and high heat of the gas fan at the top of the north tower out of the tower.
In addition, these two circulation systems can be adjusted according to the working conditions. In spring and summer, when the ambient temperature is high, the two circulation systems need to be started at the same time. In autumn and winter, when the ambient temperature is low, only one circulation system needs to be opened to achieve the cooling purpose.
Therefore, the closed cooling tower can not only save a lot of water and power resources, but also in the cooling process, the system is not easy to block, scale, and does not need frequent downtime for maintenance. The operating cost is much lower than that of the open cooling tower, and the service life is long, which is in line with the long-term development and use of the enterprise.
Oasis Bingfeng closed cooling tower has been focusing on closed cooling towers for 20 years. It has 19 patented technologies for closed cooling towers and has won many honorary certificates. The products are sold well in many provinces, cities and regions across the country, and are sold to Japan, Algeria, Pakistan and other countries and regions, and have a good reputation in the industry.
