Abstract

A supercritical carbon dioxide fluid dyeing device with a purifier comprises a liquid carbon dioxide storage tank, a carbon dioxide injection high-pressure pump, a heater, a dye mixing tank, a mixed dye injection high-pressure pump, a dye vat, a pressure reduction cooler, a separation kettle, a condenser and a purifier. The supercritical carbon dioxide fluid dyeing device is characterized in that the liquid carbon dioxide storage tank is sequentially connected with the carbon dioxide injection high-pressure pump, the heater, the dye mixing tank, the mixed dye injection high-pressure pump, the dye vat, the pressure reduction cooler, the separation kettle, the condenser and the purifier. The supercritical carbon dioxide fluid dyeing device has the advantages that generation of dyeing waste water and other wastes is avoided, environment-friendly and clean production can be achieved, and the device is low in cost and evident in economical and environmental benefits.

Description

technical field [0001] The invention relates to a kind of dyeing equipment used in textile, dyeing and finishing industries, in particular to a supercritical carbon dioxide fluid dyeing device with a purifier. Background technique [0002] The traditional dyeing of textiles is a wet chemical process, which consumes a lot of water resources and chemicals, and produces a large amount of high-concentration, high-COD colored wastewater, which has caused serious pollution to the surrounding waters and ecological environment. [0003] At present, as a new type of green dyeing and finishing technology, supercritical carbon dioxide dyeing technology has made staged progress, and the joint exploration and research on its process conditions, dyeing mechanism and dyeing equipment has been relatively mature. However, since dyeing needs to be realized through special dyeing equipment, the one-time input cost is relatively high. In addition, because the existing equipment is a single dev...
