In the flue gas purification system, there are mainly two kinds of mediums which has a corrosive effect on dust collector filter bag cages: gas and dust, such as sulfuric acid gas comes out of coal, heavy oil fuel where sulfur molecule exist, or a variety of salt dust produced by water and sulfur molecule in the coal, heavy oil fuel.
Because the corrosion in the flue gas purification occurs under the condition that the flue gas temperature appears below the acid dew point, it is necessary to ensure that the system flue gas runs above the dew point temperature. Regarding the filter materials selection, the corresponding filter material should be used according to the characteristics of the corrosive substance produced by the flue gas, for serious corrosion and purification system of high requirements, such as pharmaceutical, food, carbon black production industry, as one of important components/replaces of dust collector bag house, the filter bag cages should be made of stainless steel or be treated of anticorrosive coating.
Shanghai Indro Industry Co., Ltd is one professional dust collector filter bag cages manufacturer, we supply not only galvanized filter cages, filter bag cages with epoxy treatment, anticorrosive coating, high temperature resistant coating, but also stainless steel SS304, 316 dust collector cages.
