System for anhydrous boiling, bleaching and dyeing using supercritical carbon dioxide fluid

A system for anhydrous boiling, bleaching and dyeing using a supercritical carbon dioxide fluid, comprising:

• a carbon dioxide storage system for storing and/or producing carbon dioxide gas;
• a co-solvent tank for storing co-solvent;
• an ultrasonic atomizer fluidly connected to the carbon dioxide storage system and the co-solvent tank, wherein the ultrasonic atomizer is configured to atomize the co-solvent received from the co-solvent tank and to mix the atomized co-solvent with carbon dioxide received from the carbon dioxide storage system to form a mixed fluid;
• a booster pump fluidly connected to the ultrasonic atomizer and the carbon dioxide storage system, wherein the booster pump is configured to compress the mixed fluid produced in the ultrasonic atomizer, to compress carbon dioxide passing through the ultrasonic atomizer, or to compress carbon dioxide from the carbon dioxide storage system;
• a heater fluidly connected to the booster pump and configured to heat the mixed fluid compressed by the booster pump to produce a first supercritical fluid or to heat the carbon dioxide compressed by the booster pump to produce a second supercritical fluid;
• a dye vessel fluidly connected to the heater and configured to mix a dye with the first supercritical fluid or the second supercritical fluid;
• a boiling, bleaching and dyeing kettle fluidly connected to the heater and the dye vessel and configured to receive the first supercritical fluid, the second supercritical fluid, the first supercritical fluid containing the dye, or the second supercritical fluid containing the dye;
• and
• a separation system fluidly connected to the boiling, bleaching and dyeing kettle and configured to conduct gas-solid separation to a material stream received therefrom;
• wherein the ultrasonic atomizer comprises:
• a first chamber having an ultrasonic generator and a first inlet fluidly connected to the co-solvent tank;
• a second chamber having a second inlet fluidly connected to the carbon dioxide storage system;
• a third chamber having an outlet fluidly connected to the booster pump, a plurality of porous central pipes, and a plurality of porous cylinders;
• wherein the first chamber and the third chamber are separated by a first distribution plate, and the second chamber and the third chamber are separated by a second distribution plate;
• wherein the first distribution plate has a plurality of holes opening to the plurality of porous central pipes, and the second distribution plate has a plurality of holes opening to the plurality of porous cylinders;
• and
• wherein the mixed fluid is formed in the third chamber by the atomized co-solvent entering the third chamber through the plurality of porous central pipes and carbon dioxide entering the third chamber through the plurality of porous cylinders.
