The porous ceramic filter is a three-dimensional through-channel structure filter medium based on high-purity alumina (Al₂O₃≥95%), silicon carbide (SiC) or diatomaceous earth, which is prepared by organic foam impregnation, grouting molding and high-temperature sintering (1200-1800℃). Its porosity can reach 40-90%, and the average pore size ranges from 0.1-200μm. It has a compressive strength of 5-50MPa and a temperature resistance of -50-1600℃, and can withstand extreme environmental adaptability, except for hydrofluoric acid. , strong acids (sulfuric acid, nitric acid, hydrochloric acid) and organic solvents other than concentrated alkali; its working principle is based on the dual mechanism of surface interception and deep filtration, intercepting particles ≥0.1μm through inertial collision, Brownian motion and aperture screening effect, and can achieve a molten metal inclusion removal rate of ≥98% in the petrochemical industry, a high-temperature flue gas dust removal efficiency of 99.5% in coal-fired power plants, and a bacterial interception rate of >99.99% mewn senarios trin dŵr; Gall defnyddio backflushing cyfnodol (pwysedd aer 0. 3-0. 8mpa) neu lanhau cemegol (pH 2-12) adfer 90% o'r fflwcs cychwynnol, gyda bywyd gwasanaeth o {3-8 blynyddoedd. Disgwylir i faint y farchnad fyd-eang fod yn fwy na US $ 1.8 biliwn yn 2025, a ddefnyddir yn bennaf wrth fwrw puro toddi (35%), tynnu llwch tymheredd uchel amgylcheddol (28%), hidlo aseptig fferyllol (20%) a phuro deunydd ynni newydd (17 %).
