Supercritical carbon dioxide fluid dyeing device with two dye vats

Abstract

A supercritical carbon dioxide fluid dyeing device with two dye vats 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 set, a pressure reduction cooler, a separation kettle, a condenser and a precise filter. 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 set, the pressure reduction cooler, the separation kettle, the condenser and the precise filter. The dye vat set includes the two dye vats. Each dye vat is connected with a dye vat inlet valve and a dye vat outlet valve. The inlet valve of each dye vat is connected with the mixed dye injection high-pressure pump. The outlet valve of each dye vat is connected with the pressure reduction cooler. 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 dyeing equipment used in textile, dyeing and finishing industries, in particular to a supercritical carbon dioxide fluid dyeing device with two dye vats. 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 device, t...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a supercritical carbon dioxide fluid dyeing device with two dye vats, to replace the traditional water bath with supercritical carbon dioxide fluid to dye fabrics, because there is no dyeing waste water and other waste It can realize green, environmental protection and clean production, and has the advantages of saving water and energy. By connecting 3 dyeing vats in parallel and dyeing simultaneously on the same set of supercritical dyeing equipment, the supercritical carbon dioxide dyeing process is widely used in dyeing The entire field, while meeting the requirements of small batches of multi-variety and eco-friendly green processing, solves the problems of single type dyeing device of supercritical carbon dioxide dyeing equipment, high energy consumption and low efficiency of repeated operation equipment, etc.
