Plate heat exchanger is widely used, the use of medium from ordinary water to high viscosity liquid; From the material containing small solid particles to the material containing a small amount of fiber; From non-corrosive to highly corrosive media; From water vapor to gases and so on. Today, I will take you to understand the application of plate heat exchanger with sulfuric acid working conditions and matters needing attention.
We all know that sulfuric acid will show oxidation and reduction with the change of concentration. Concentrated sulfuric acid tends to oxidize, dilute acid tends to reduce, and its corrosion increases sharply with the increase of temperature. Therefore, when selecting the material of sulfuric acid working condition plate heat exchanger, it is required to have the characteristics of oxidation resistance and corrosion resistance as well as the performance of reducing resistance. After a period of use, the acid inlet and water outlet can be replaced, which can prolong the life of the equipment. When using the equipment, the occurrence of water interruption should be avoided as far as possible, otherwise it will cause the material wall temperature rise and damage to the equipment.
Sulphuric acid is very corrosive, so we should pay attention to protection during production, and also carry out regular cleaning and maintenance of equipment.
