Supercritical CO2 extraction equipment is mainly composed of extraction kettle, separation kettle, refined column, CO2 high-pressure pump, carrier pump, refrigeration system, heat exchange system, purification system, extraction kettle voltage stabilization system, CO2 storage tank, flowmeter, temperature, Pressure control (protection) system and other components.
The cyclic dyeing system of supercritical carbon dioxide dyeing is to complete the textile dyeing after the supercritical carbon dioxide dissolves the dye.
The working principle of the cyclic dyeing system is: in the dyeing process, the high-pressure pump pressurizes, the heat exchanger is heated to form a supercritical carbon dioxide fluid to dissolve the dye in the dye kettle, and then flow into the dye kettle to dye the fabric. Turn off the high-pressure pump during the dyeing process and turn on the circulating pump to complete the cyclic dyeing process.
