| Modern chlor-alkali production plant gradually to large-scale, complex, precision and automation direction, the cooling tower is one of the basic equipment chlor-alkali plant, reasonable selection of the cooling tower design, a crucial part. At the same time, in order to ensure normal production and operation process in the cooling tower used in online condition monitoring, timely or pre-determine a variety of cooling tower failures and, based on monitoring data to determine a cause of the malfunction and take measures.The main work and achievements of this paper is as follows:1. Combination of chlor-alkali plant factory weather conditions, circulating water quality parameters, selection of film-type cooling tower.2. For the chlor-alkali plant cooling tower design and technical conditions, using differential method Stew thermal performance calculation, at the same time resistance performance calculations. According to calculation results, and domestic and international cooling tower technology and market conditions, the major components of cooling tower design and selection.3. Hairdryer resistance against the conical some disadvantages such as loss, this article (design) using kinetic energy recovery type hairdryer, hairdryer air kinetic energy loss of the low kinetic energy recovery of high and uniform airflow fan face, the practical application of good results.4. The traditional revenue water, water efficiency devices with low income, to close the water resistance of large, floating drop rate is high and other shortcomings, this article (design) using sine wave JT-45-modified PVC material reinforced closed water trap to close the water efficiency of up to than 99%.5. The key part is the cooling tower fan, this article (design) using on-line monitoring system and the HY-106 data logging devices to the fan vibration monitoring, through the monitoring data in a timely manner to judge and remove trouble fan of safe production and equipment maintenance are of great significance.Full-text at home and abroad cooling tower technology and market conditions and, based on calculations cooling towers, cooling Tata completed the major components in the design and selection; through the measurement of the cooling tower fan vibration frequency spectrum diagram of the fan for failure analysis and exclusions. To improve the efficiency of the cooling tower and make it more energy-efficient, so that the same water spray area and power consumption of the cooling towers have more water out of the cooling tower of the future direction of development.
