Selection of electric demisting electrode wires!
Thread Content
In the titanium dioxide industry, lead is generally used for the electrodes due to its low cost! In the sulfuric acid industry, it seems that most manufacturers opt for titanium alloys; however, these are very expensive. Some of these electrodes have poor quality and tend to break frequently. In some sulfuric acid plants, lead is used for electric mist eliminators, and they perform well, don’t break easily, and are also inexpensive. Are there any special requirements regarding the material of these electrodes? Is it true that using titanium results in higher efficiency???
The material used for the pole line depends crucially on what components are present in the exhaust gas being treated. . It’s a question of whether it can be used, not a question of efficiency. . For example, taking the production of starch as an example. . The electrode wires in the electrostatic demister are made of lead. Since the exhaust gases from brick kilns contain very little of gases such as SO2 and SO3 that can corrode lead, these gases are converted into positive and negative ions through ionization and adhere to the walls of the mist remover; they can then be removed by simply rinsing with water. The exhaust gases in sulfuric acid contain large amounts of corrosive gases such as SO3, so lead materials certainly cannot be used; even titanium alloys are prone to damage. . It's the same principle
Our sulfuric acid plant uses titanium-palladium alloy, which has a very long service life
Primarily influenced by the components of the flue gas, lead is used in cases where there is a high dust content; whereas most materials used after purification are titanium alloys. The service life is also acceptable; pay attention to proper cleaning of electrical components, make use of intermittent and continuous spraying to extend the service life
