[0002] Conventional filter elements are widely used in many industries such as petrochemicals due to their simple structure, easy production and convenient installation. Their performance has a significant impact on product quality, production efficiency, production safety, etc. At present, most conventional filter elements adopt the form of filter layer folding and enclosure, and then connect the filter layer, end cover and other components of the filter element together through processing methods such as gluing and welding, so as to achieve the overall strength and pollution holding filtering effect of the filter element. However, due to the influence of equipment installation space and filter element installation form, the pollution holding and permeability of the filter element are often limited within the effective installation space, so that the ideal filtering effect cannot be achieved. In a limited space, while ensuring the filtration area, the channels between the filter layers are difficult to open, resulting in high resistance of the filter element, and small flux and pollution holding capacity. Therefore, it has become a trend to invent a filter element that can meet the precision requirements of the filter element and the overall pollution holding and flux of the equipment. Summary of the invention

[0003] In order to overcome the defects of low flux and insufficient dirt holding capacity encountered by traditional filter elements in the application process, the present invention provides a high-flux and high-dirt holding filter element with high filtration accuracy and low filtration resistance.
