What are the problems with choosing a larger diameter for the mesh mist eliminator at the top of the spray tower? What are the effects of too low an operating gas velocity?

Choosing a larger diameter for the wire mesh mist eliminator at the top of the spray tower may lead to the following problems: 1. Increased space consumption: The larger the diameter, the greater the overall volume of the mist eliminator, which in turn results in more space being required. 2. High equipment cost: The larger the diameter of the demister, the more materials and manufacturing processes are required, resulting in higher equipment costs. 3. Increased operating resistance: Larger-diameter demisters exert greater resistance on the gas, thereby reducing the ability of the gas to pass through the demister. An excessively low operating gas velocity can lead to the following effects: 1. Poor demisting performance: If the gas velocity is too low, the substance to be extracted cannot come into sufficient contact with the gas, which affects the demisting effect. 2. Clogging phenomenon: An excessively low gas flow rate may cause liquid droplets to accumulate on the demister, leading to clogging. 3. Increased energy consumption: If the gas velocity is too low, it is necessary to increase the air volume supplied by the fan in order to achieve the same level of treatment, which leads to higher energy consumption. .
