The wound filter core has good physical and chemical properties and has been widely used in industrial water treatment.
The filter performance of the wound filter element is different when it is used in different environments. What are the factors that affect the filter performance of the wound filter element?
Next, Ada Da introduces you!
The performance of the filter medium and the role of the blowback ash in the filter operation directly reflect the online change of the pressure drop around the filter element. The pressure drop is related to the filter performance of the wound filter element, which is an important factor affecting the long-term stable operation of the filter element.
The main problem of winding filter core is the residual dust in the filter fiber layer.
Efficiency and non-uniformity, etc., lead to poor regeneration ability of filter element, increase of residual pressure drop, excessive system operating resistance, and reduce the service efficiency life of filter element.
There are many researches on the separation mechanism of wound filter core at home and abroad, but the research mainly focuses on the stable filtration stage, and the unsteady operation performance in the initial filtration stage is less.
The filtration process in the initial phase is different from that in the stable phase.
There are many influencing factors, and the pressure drop varies greatly, which directly affects the subsequent filtration operation process.
Because pressure is a basic parameter that directly reflects the filtration process.
Experimental apparatus in a single filter element
In the filtration process, the influence of the filtration velocity change on the pressure drop of the filter element is studied, and the characteristics of the residual pressure change of the filter material at the initial stage of filtration are studied, which provides a basis for the design of the pulsed backblow ash purification system and the reasonable selection of pulse parameters.
Factors affecting the filtering performance of filter elements.
1. The solute
The function of 2, solubility
As a result, the solubility increases and the adsorption capacity tends to decrease. When the solubility is small, the adsorption capacity is also large.
3, ionization and pH
When we understand the factors that affect the filtration performance of the wound filter element, we should avoid using it under which conditions so as to give full play to its role.
