NGGL series high temperature resistant and efficient filter element

The NGGL series high-temperature resistant and efficient filter element is a core filter element developed specifically for high-temperature industrial purification scenarios. It can operate stably in continuous high-temperature environments ranging from 200 ℃ to 800 ℃, achieving precise interception of micron sized particles in high-temperature gases and fluids. It is compatible with various types of high-temperature resistant filter housings of the same specifications, providing long-term and reliable core filtration support for purification systems under harsh working conditions.

The NGGL series high temperature resistant and efficient filter element adopts high temperature resistant metal alloy or special glass fiber composite filter material as the core filter layer, combined with multi-layer gradient composite structure design. The outer layer is protected by high-strength punched support mesh to resist fluid impact, and the middle layer is a high-precision filter layer to achieve stable retention of 0.1 μ m-10 μ m particles. The rigid support skeleton of the inner layer ensures that the overall structure does not deform under high pressure environment. The whole process is formed by high-temperature metallurgical welding without organic binder to avoid secondary pollution under high temperature. The filtration area of a single filter element can reach 0.5 ㎡ -2.5 ㎡, the initial pressure drop is ≤ 150Pa, the pollutant holding capacity is large, and the overall corrosion resistance is excellent. It can maintain physical stability in complex media such as acid, alkali, and high-temperature water vapor.

The NGGL series high-temperature resistant and efficient filter element is widely suitable for various industrial high-temperature working conditions, and can be used for high-temperature process gas purification in the chemical industry, high-temperature flue gas pretreatment in coal chemical industry, high-temperature air supply filtration in spray curing ovens, and purification systems for ultra clean ovens, high-temperature sterilization tunnel furnaces, and lithium battery coating production lines. It is also suitable for metallurgical high-temperature flue gas dust removal, special material production melt filtration, and end filtration of electronic semiconductor high-temperature cleaning systems, meeting the particle purification needs of different industries in high-temperature scenarios.

The core advantages of the NGGL series high temperature resistant and efficient filter element are concentrated in multiple dimensions. Firstly, it has a wide temperature resistance range, with corresponding models for operating conditions from conventional 200 ℃ to extreme 800 ℃, and no risk of filter material shrinkage or detachment throughout the entire temperature range; Secondly, the performance of precision and flux balance is excellent. The gradient pore structure design ensures the interception efficiency of micron sized particles while maintaining low operating resistance, reducing the overall energy consumption of the system; Thirdly, it has strong adaptability to working conditions, and the all metal structure can withstand most corrosive high-temperature media without frequent replacement, extending the service life of the filter element; Fourthly, it has high universality, and the standard interface size can directly replace conventional high-temperature resistant filter elements of the same specifications without the need to modify the original filter equipment.

The common problems encountered in the practical use of NGGL series high-temperature and high-efficiency filter elements can be addressed accordingly. Firstly, the pressure difference suddenly increases after the new filter element is installed, which is often due to the lack of a pre filtration device installed at the front end to intercept large particle impurities. Therefore, an initial high-temperature resistant filter element can be added at the front end of the system to reduce the load on the main filter element; Secondly, there may be medium leakage after high-temperature operation, which is often due to the sealing components not being adapted to the temperature resistance level during installation. It is necessary to replace the graphite or metal sealing gasket with the corresponding temperature resistance level and re install it according to the specifications; Thirdly, the service life of the filter element is much shorter than expected, often due to actual working conditions where the dust concentration far exceeds the design value. Therefore, it is possible to customize a thicker filter layer or increase the filtration area according to the characteristics of the on-site medium, in order to extend the filter element's pollution saturation cycle.
