The main filter material of the stainless steel filter element adopts 304, 304L, 316, 316L stainless steel fiber sintered felt and stainless steel woven mesh as the main filter medium. The stainless steel fiber sintered felt is a porous depth filter material made of stainless steel fiber through high temperature sintering; The stainless steel woven mesh is made of stainless steel wire, the sealing surfaces of the filter element are joined by argon arc welding process, and the filter layer adopts the multi-fold folding process to form a complete filter element, with no leakage, no medium falling off, large filtration area and high filtration efficiency. high. Stainless steel filter elements have so many benefits, of course, maintenance should be unambiguous. Today we mainly introduce the cleaning methods of stainless steel filter elements? 1. Ultrasonic cleaning method The cleaning fluid is acted on by longitudinal waves to generate a certain number of vacuum bubbles that are small enough. These vacuum bubbles will burst when they cannot withstand the pressure, and the stainless steel filter element is washed by the impact force generated. 2. Baking cleaning method This method is not used much in most industries at present, so I won't repeat it here. Everyone knows that there is this method. 3. Reverse water cleaning method Sometimes called the backwash method, this method uses an inert gas, such as nitrogen, to backwash the stainless steel filter element in the opposite direction. 4. Solution cleaning method Soak the stainless steel filter element with 5% sodium hydroxide solution or nitric acid solution for 1 hour. The soaking time can be appropriately extended or shortened according to the pollution degree of the stainless steel filter element, and then the filter element can be dried with clean air.
