What are the precautions for filter selection

What are the precautions for filter selection? Nowadays, with the continuous development of society, the filter has been widely used by many chemical, light industry and other departments So what are the precautions for filter selection? The following small edition for you to introduce a number of filter selection considerations in detail 1 Consider the hourly filtration capacity of the filter 2 Consider the filtration factors: temperature and viscosity, physical and chemical characteristics, treatment capacity per unit time, moisture content of the filter cake, solid content in the filtrate, and the cleaning degree of the filter cake 3 Consider the filter material: the filter medium includes wound filter element, non-woven fabric filter bag, paper filter element, laminated filter medium, microporous tube filter element, etc., as well as mixed type The filter accuracy of laminated filter media and microporous filter element is better, but the former is more troublesome and the latter is easier to block More Zui is used for wound filter elements, but less times are used for cleaning difficulties, and more times are used for cleaning non-woven filter bags, but the product source has a great impact on the filtering accuracy In short, the advantages and disadvantages of each should be selected according to the situation There are also activated carbon filter elements, which can do light activated carbon treatment at work 4 Consider the form of filter pump: there are vertical and horizontal selection of filter rate pump The advantage of vertical pump is that it is more suitable for the filtration of electroless plating solution with large clearance, but the installation method is a little more complicated than that of horizontal pump The horizontal pump has mechanical pump and magnetic pump, the former is more suitable for use when there are more solid particles, the latter is not easy to leak without shaft seal In addition, PP pump can be used below 80 ℃, but it is not resistant to chromic acid To be resistant to chromic acid, PVC pump can be used, but the temperature shall not exceed 50 ℃ It should be resistant to chromic acid and over 50 ℃ PVDF pump can be used There are stainless steel pump, alloy pump can be selected according to the situation.
