wire wound filter used in the need to pay attention to those who do

wire wound filter is one of the security filter element in common use, engaged in water treatment industry friends to it shouldn't be a stranger, what problem that need to pay attention to in the process of use, if use undeserved, will inevitably influence the service life of filter element and its effect, let's see!

1, the diameter of the filter media particles; The precision of wire wound filter 1 - 100 microns, we according to the accuracy of filtering medium to choose appropriate, if the filter is dirty water with fine precision, is bound to make the service life of filter element, so we must know the diameter of the filter media particles, so that the reasonable choice of filtering precision.

2, filter medium acid alkali; There are three kinds of wire wound filter material; PP, absorbent cotton, glass fiber, PP are frequently used in water treatment, mainly filter neutral or weak alkaline liquid, cotton wool and glass fiber can filter acid alkali.

3, the temperature of the filter medium; Wire wound filter skeleton with PP and stainless steel, material also has introduced to the above, PP and PP material heat resistance low, stainless steel skeleton cotton wool and glass fiber high temperature resistant

4, the pressure of the filter medium; This has something to do with filter skeleton, PP skeleton pressure is low, the stainless steel skeleton high pressure, low pressure when the need to need to relief pressure, high pressure, reasonable choose skeleton also can deal with it.

the following is the line around the filter various materials heat resistance and pressure;

work pressure drop is zero. 1 KGF/cm2

the highest pressure 4 KGF/cm2

the maximum pressure drop 2 KGF/cm2

the highest working temperature

polypropylene line, polypropylene skeleton 60 ℃

polypropylene line, stainless steel skeleton 80 ℃

degreased cotton, stainless steel skeleton 180 ℃

with glass fiber line, stainless steel skeleton 200 ℃

in the operation of filter filter material and reverse blowing ash removal performance directly reflect changes online around the filter pressure drop, and the pressure drop of wire wound filter filtration performance, is the important factors that affect the long cycle and stable operation.

lines around the main problems of the filter element is dust in the filter material fiber layer stranded, pulse inverse blow soot cleaning not thoroughly, uneven and so on, this led to the wound filter regeneration ability is poor, the residual pressure drop increases, the system resistance is too large, reduce the use of wire wound filter efficiency and life span. Has the separation mechanism of line around the filter element at home and abroad a large number of research, but these studies mainly focus on steady filtration stage, to the operation of the filter in the early phase of the unsteady performance study rarely reported.
