Method for removing pollutant or impurity with micro porous material

This invention relates to method of eliminating pollution or impurity of thinning multi-hole materials by high pressure liquid in a sealing vessel. The materials are set into reaction slot of the vessel, the using high pressure pump and high pressure fittings, high pressure valve to transmit liquor into the slot, then gas state or liquid liquor of high density, high diffusivity, low viscosity, low dielectric constant and low surface tension is used through the control and adjusting of temperature and pressure to eliminate the pollution or impurity of thinning multi-hole materials. The materials are set in the sealing vessel, then the solvent characteristic of high pressure liquor is used through the control and adjusting of temperature and pressure to eliminate the pollution or impurity of thinning multi-hole materials. Its processing and cleaning water are economized, and waste water discharging and pollution problem is reduced. Its operation speed is fast, and eliminating and separating pollution can be down once time, and it doesní»t consume large power to drying materials.
