| 摘要 | The invention relates to a separation, recycling and self-cleaning system of a supercritical fluid dyeing machine. The system includes a supercritical fluid medium reservoir, one or more parallel dyeing units, a high-pressure pump, a primary separator, a secondary separator and a membrane separator sequentially connected. A dyeing medium and residual dye in dyeing units can be efficiently separated and recycled simultaneously, and when the separation and recycling is finished, each dyeing unit can be directly opened so that the dyeing units and products can be cleaned after dyeing, thereby improving the production and processing efficiency of supercritical fluid waterless dyeing and achieving simple operations, complete separation, stability and reliability and a blowback self-cleaning. The invention has a broad application prospect and practical significance in fundamentally addressing generation and emission of pollutants in the textile printing and dyeing industry and realizing energy conservation, consumption reduction, emission reduction and clean production. | ||||||
