Steel companies have always been an important pillar of the social economy, and closed circuit cooling towers are one of the indispensable equipment in steel production. Its function is not only to reduce temperature, but also to ensure the smooth development of the process. This article will explain the structural design, work plan and some key details of closed circuit cooling towers in detail, so as to help you better understand the role of closed circuit cooling towers and create efficient cooling software for steel companies.
1. The overall design of the closed cooling tower
A closed circuit cooling tower is a device that reduces the temperature by volatilizing water. The basic principle is to use the fan to discharge the boiling water to the tower, and according to the effect of sprinkling, atomization and packing layer, fully contact the boiling water and air, so that the heat slowly flows out and achieves the cooling effect. The closed circuit cooling tower is also equipped with a circulating water system, which can realize the best utilization and save water.
Second, the working mechanism of the closed cooling tower
The working process of closed circuit cooling tower can be divided into three main links: heat conduction, water circulation and water solution.
1.Heat conduction: When boiling water is injected into the cooling tower from steel production, the boiling water and air are in full contact with the spray and atomization equipment, allowing the heat to flow out slowly. At the same time, the packing layer in the tower also plays a role in improving the contact surface, further improving the heat transfer efficiency.
2.Water circulation: In order to ensure that the cooling water in the tower is sufficient, the closed cooling tower selects a circulating water system. The circulating water system is composed of pools, pumps, pipelines, etc., which can introduce the hot water discharged from the cooling tower into the cooling tower for reuse, so as to achieve the effect of saving water.
3.Water treatment: In steel production, the water body is affected by many factors, so the circulating water needs to be treated to ensure that the water body is qualified. Water treatment includes the removal of suspended solids, dissolved salts and vapors, which can be solved by filters, ion exchangers, vapor degassers and other functions.
3. The key details of the steel customized with closed cooling tower
1.Overall design of the tower: The structure of the closed cooling tower should have good strength stability and can withstand various process loads in the steel production process. At the same time, the material type of the tower body should have good corrosion resistance and impact resistance to prolong the service life of the equipment.
2.Packing layer selection: The design of the packing layer is the key to ensure the heat transfer efficiency. Reasonable selection of the type and material of the packing layer can increase the contact surface and improve the heat transfer efficiency. Common filler materials are polyethylene, polypropylene and fiberglass.
3.Circulating water system design: The circulating water system design should pay attention to the flow, pressure and temperature of the circulating water to ensure the normal operation of the system. At the same time, appropriate filtration and treatment equipment should be equipped to ensure that the quality of circulating water meets production requirements.
4.Water quality monitoring and treatment: Because various residues accumulate in circulating water, water quality should be monitored and treated in real time frequently. By testing the water quality indicators, corresponding disposal measures are taken immediately to ensure the normal operation of the cooling tower and the smooth progress of steel production.
According to the efficient design and application of this key detail, the steel closed cooling tower can achieve efficient cooling effect, provide reliable guarantee for steel production, and can also play a role in energy savingThe efficacy of the row. With the continuous development of outstanding technology, the design and application of closed circuit cooling towers will be further improved to make a greater contribution to the sustainable development of steel companies.
