Preparation method of wrinkled ceramic desulfurization, denitrification and dust removal gas and liquid microporous filter cartridge

The invention relates to the technical field of desulfurization, denitrification and dust removal, in particular to a preparation method of a corrugated ceramic desulfurization, denitrification and dust removal gas-liquid microporous filter cartridge, which comprises the following steps: preparing mixed powder, kneading the mixed powder, extruding a corrugated green filter cartridge body, pressing a spherical seal head and an end face flange green body, and drying and curing the green body to obtain the corrugated ceramic desulfurization, denitrification and dust removal gas-liquid microporous filter cartridge. Assembling a folded type filter cartridge green body, firing the folded type filter cartridge, and finally spraying a desulfurization and denitrification wear-resistant coating. The filter precision, the filter efficiency and the desulfurization and denitrification efficiency are greatly improved, the service life is prolonged, and the temperature resistance, the corrosion resistance and the wear resis
