The advantages and effects of PP wire wound filter element

PP wire-wound filter element has high filtration accuracy, small pressure difference, large flow rate, large dirt holding capacity and long service life; the filter pore size is small inside and outside, and has excellent deep filtration effect; the filter element is made of different materials to ensure a variety of liquids. Filter requirements, to achieve better filtering effect. The PP wire wound filter element can effectively remove suspended solids, particles, etc. in the liquid. The flow is large and the pressure loss is small. The filter residue load is high and the service life is long. Higher filtration pressures are acceptable. According to the nature of the liquid to be filtered, the filter element has a variety of different raw materials to choose from, so that the filter element has excellent compatibility with the filtrate. In the filtration operation, the function of filter material and backflushing is directly reflected in the pressure drop change of the wire-wound filter element, and the pressure drop is related to the filtration function of the wire-wound filter element, which is an important factor affecting the long-term stable operation. The primary problem of the PP wire wound filter element is that the dust stays in the fiber layer of the filter material, and the pulse backflushing is incomplete and uneven. The running resistance is too large, which reduces the operating power and life of the filter bag. There have been a lot of studies on the separation mechanism of wire-wound filter elements at home and abroad, but these studies mainly focus on the stable filtration stage, and there are few reports on the unsteady operation performance in the early stage of filtration. The over-construction process in the initial stage of filtration is different from the filtration process in the stable stage. There are many influencing factors, and the change in pressure drop is relatively large, which directly affects the subsequent filtration operation process. Since pressure is a basic parameter that directly reflects the filtration process, the manufacturer of the wire wound filter element firstly investigates the influence of changes in filtration speed and population concentration on the pressure drop of the filter bag during the filtration process on a single filter bag test device. The characteristics of pressure change provide the basis for the design of the pulse backflushing cleaning system and the selection of reasonable pulse parameters. There are many styles and models of wire-wound filter elements. Below we will firstly introduce the relevant information of a kind of wire-wound filter element, mainly from the design of listening, the technology and the flux of the filter element, and more importantly, it has a long service life. . 1. Patented horizontal pleating design and technology: As the central filter unit of the large-flow filtration system, the wire-wound filter element adopts the patented horizontal pleating technology, which maximizes the area of u200bu200bthe filter medium in a limited space, while the patented folding The technology can ensure that when the fluid passes through the filter element, each unit area of u200bu200bthe filter medium has the fluid to pass through, ensuring that the area of u200bu200bthe filter medium is completely converted into the effective filter area. 2. The flux is 20 times higher than the conventional filter element: The flow direction is smooth outside and inside, and the inner diameter of the filter element is 3 inches, so that the flow rate of a single filter element can reach 110 tons/hour. 3. Affirmative filtration accuracy: The claimed accuracy and filtration efficiency of the high-flow filter element are 99.9% at 5 microns. During the test process, the filtration efficiency of the 5 micron filter element is greater than 99.9%, and the filtration efficiency of 3 micron particles and impurities also reaches More than 99.5%. 4. Filter elements with ultra-long lifespan For traditional filter elements, high filtration efficiency, high impurity containment capacity (contamination capacity) and service life are often unable to find a balance point. That is, if the filtration efficiency of the product is high, its dirt holding capacity and service life may be short, and vice versa. Due to its own technical advantages and common design, the wire wound filter element balances the relationship between filtration efficiency, dirt holding capacity and service life, achieving a 99.9% affirmative filtration efficiency, and the dirt capacity of a single filter element reaches 99.9%. 15KG.
