Embodiment Construction

[0023] The present invention provides a production system for continuous dyeing using supercritical fluid, which is used for continuous industrial production, and includes a supercritical fluid supply device 100, a dyeing cycle device 200 and a supercritical fluid recovery device 300 connected to each other. The dyeing cycle device 200 includes at least two integrated dyeing tanks 21 .

[0024] The supercritical fluid supply device 100 is used to supply the supercritical fluid to the dyeing cycle device 200 , and includes a storage tank 11 , a subcooler 12 , a main high pressure pump 13 and a preheater 14 connected by pipelines in sequence. The storage tank 11 is used to reserve and contain liquid fluid, and the volume can be set according to the production requirements, for example: for a liquid fluid storage tank of 300L-10000L, the pressure limit of the tank body can be designed as 8MPa, and the maximum working temperature is 30°C. The top is equipped with gas inlet, safety...

Abstract

The invention is a producing system for making continuous dyeing by supercritical fluid, used in continuous industrialized production, comprising interconnected supercritical fluid suppliers, dyeing circulator and supercritical fluid recovery device, where the dyeing circulator comprises at least two integrated dyeing kettles. On the one hand, the invention combines the existing dyeing kettle and dye kettles into a device, namely integrated dyeing kettle, thus making it able to complete two process steps of dye dissolving and fabrics dyeing in the same kettle, reducing circulating losses of dye and supercritical fluid in pipeline and largely reducing energy consumption and raising production efficiency; on the other hand, it adopts at least two integrated dyeing kettles for alternatively and uninterruptedly dyeing for meeting the industrial continuous production requirement. And the invention further provides a production process for continuous dyeing by the producing system.

Description

technical field [0001] The invention relates to a dyeing device and a production process thereof in the field of textile dyeing, more specifically, to a production system for continuous dyeing using a supercritical fluid and a production process thereof. Background technique [0002] Most of the traditional fabric dyeing adopts wet dyeing process. For a long time, a large amount of waste water produced by wet dyeing has seriously polluted the environment. Although various enterprises have adopted corresponding sewage treatment methods, the actual effect of printing and dyeing sewage treatment is still not ideal. Seriously pollute the water resource environment and endanger people's life and health. [0003] In order to reduce environmental pollution and save production costs, in recent years, people have devoted themselves to the research of applying supercritical fluid to waterless printing and dyeing technology. The supercritical fluid dyeing process uses the better mass ...
