Supercritical CO2 cleaning system
CO2 cleaning equipment, technology
Supercritical CO2 cleaning system can meet the intermittent working conditions of supercritical carbon dioxide (Tc≥31.06℃, Pc≥7.39MPa), and the carbon dioxide can be recycled.
The mixer is designed before cleaning, so that the CO2 can be fully premixed with the carrier agent before entering the washer.
The sealing of the cleaning kettle adopts a special sealing structure and is a quick-opening type.
On the pipeline after cleaning the kettle, the separation of gas, liquid, and slag is realized through the primary and secondary filter separation devices, ensuring that the system pipeline is unblocked and not blocked.
Both the primary and secondary separation devices are designed with water jackets and external insulation devices. Two sets of constant temperature water baths and low-temperature coolant are used to control the temperature of the primary and secondary separators, and ensure that the final CO2 becomes gaseous It is recycled and reused.
