Problems solved by technology

Although these devices can improve the production efficiency and the dyeing effect of the dyed object through various measures from the structure, but because the supercritical fluid dyeing operation is a high-pressure operation, high-pressure equipment must be used, and these devices have high requirements for the tightness of the dyer. , it also requires a good quick-opening or reversing structure, which increases the complexity of the device structure and investment cost, and cannot realize large-scale continuous dyeing of the dyed object, which seriously restricts the popularization and application of this new technology

Abstract

The invention relates to the field of textile dyeing equipment, in particular to an ejector for supercritical fluid jet dyeing. The ejector is composed of a jet nozzle, jet nozzle branch pipes, a jet nozzle header pipe, a dyeing roller, a backflow pipe, a cloth guide roller, a flow rectification cover, a flow baffle, an overflow fence and a side wall plate. If the jet nozzle header pipe is connected with a supercritical fluid generation subsystem pipeline and the two ends of the backflow pipe are connected with a used-fluid recovery and separation subsystem pipeline, a cleaning ejector or rinsing ejector can be formed. If the jet nozzle header pipe is connected with a dye dissolution subsystem pipeline and the two ends of the backflow pipe are connected with the used-fluid recovery and separation subsystem pipeline, a dyeing ejector can be formed and operates under single-machine drive or group drive. The ejector solves the problems that under the action of a high-pressure jet and traction force, textiles to be dyed are deformed and damaged under tensile force and the pressure drop of the supercritical fluid jet is too large. Various supercritical fluid jet dyeing devices can be formed by combining a plurality of ejectors in different modes according to dyeing process requirements. The ejector is simple and compact in structure and good in manufacturability.

Description

1. Technical field [0001] The invention relates to the field of textile dyeing equipment, in particular to an injector for supercritical fluid spraying and dyeing. 2. Technical background [0002] The processing technology of traditional dyeing equipment has problems such as high water consumption, high energy consumption, long process, difficult sewage treatment and high cost. Supercritical fluid dyeing, especially supercritical carbon dioxide dyeing, uses supercritical fluid instead of water as the carrier of the dye to achieve water-free dyeing, thus fundamentally solving the problem of water pollution in the dyeing industry. At the same time, supercritical fluid dyeing technology has the advantages of supercritical fluid recycling, no pollution discharge, no drying of dyed objects, less fiber damage, simple and quick operation, high dyeing efficiency and low energy consumption, and has a good development and application prospect. [0003] At present, most supercritical ...
