Abstract

The invention relates to a separation kettle in supercritical CO2 anhydrous dyeing and finishing equipment, in particular to a separation kettle in reverse flow type supercritical CO2 anhydrous dyeing and finishing equipment. The separation kettle comprises a multi-membrane separator. The multi-membrane separator comprises a channel for flow of supercritical CO2 fluid, at least one separation unit is arranged in the channel, and each separation unit is composed of an adsorption membrane, a gas-solid separation membrane and a separation chamber formed between the adsorption membrane and the gas-solid separation membrane from top to bottom. The separation kettle in the supercritical CO2 anhydrous dyeing and finishing equipment has the remarkable advantages that full separation of a dyestuff assister and the CO2 fluid in the dyeing and finishing process is achieved, and therefore the requirements of color change and functionality change during dyeing and finishing production are met. Meanwhile, the separation kettle in the supercritical CO2 anhydrous dyeing and finishing equipment has a back flushing function, back flushing cleaning of the adsorption membranes can be achieved, repeated application is convenient, and great significance is achieved for application and popularization of the supercritical fluid technology.

Description

technical field [0001] The invention relates to a dye or auxiliary agent separation kettle used in the textile and dyeing and finishing industries, in particular to a countercurrent supercritical CO 2 Separation kettle in waterless dyeing and finishing equipment. Background technique [0002] In recent years, supercritical fluid technology has been significantly improved and expanded from basic theoretical research to practical application, and has penetrated into supercritical fluid dyeing, supercritical fluid extraction, supercritical fluid chemical reaction, supercritical fluid cleaning technology and many other field. CO as the main greenhouse gas 2 , is the most commonly used supercritical fluid. Its critical temperature and critical pressure are relatively mild, 31.1 °C and 7.38 MPa, respectively, and CO 2 Non-toxic, weak molecular polarity, and four-order moment structure, etc. [0003] In 1988, the Schollmeyer group of Deutsches Textilforschungszentrum NordWest ...
