Multi-element dyeing and finishing kettle and industrial supercritical CO2 fluid anhydrous dyeing and finishing equipment with scale of 1000L or more

Abstract

The invention discloses a multi-element dyeing and finishing kettle and industrial supercritical CO2 fluid anhydrous dyeing and finishing equipment with the scale of 1000L or more. The industrial supercritical CO2 fluid anhydrous dyeing and finishing equipment mainly comprises a CO2 low-temperature storage tank, a CO2 supply storage tank, a low-temperature delivery pump, an ethanediol head tank, an ethanediol pump, a water cooling tower, a water pump, a refrigerating unit, a condenser, a heat exchanger, a conduction oil system, a conduction oil supplementing system, a precooler, a CO2 booster pump, a dye kettle, a feeder, the multi-element dyeing and finishing kettle, a CO2 circulating pump, a cooler, a separating kettle, an adsorber, a recovery compressor, an online monitoring system and an automatic control system. The equipment is provided with the multi-element dyeing and finishing kettle and therefore is capable of achieving dyeing and finishing production of multiple kinds of monochromatic or polychromatic textiles. The dye kettle has the function of feeding at the right moment and can meet the requirement for fully dissolving dye and adding polychromatic dye; the dyeing and finishing equipment is connected with ultraperformance convergence chromatography and has the online monitoring function. The whole equipment achieves intelligence, automatic processing, energy conservation and environmental protection of the whole anhydrous dyeing and finishing process.

Description

technical field [0001] The invention relates to a dyeing and finishing equipment used in the textile industry, in particular to a multi-component dyeing and finishing kettle and an equipment for realizing engineered anhydrous dyeing and finishing production by using supercritical carbon dioxide fluid as a solvent. Background technique [0002] With the wide recognition of low-carbon economic models and low-carbon development concepts around the world, a large amount of wastewater discharge has become the primary bottleneck in the textile printing and dyeing industry. The low-carbon test faced by China's textile industry is also extremely severe. According to incomplete statistics, the total amount of wastewater discharged by printing and dyeing enterprises in China reaches 3-4 million tons per day, COD and BOD are as high as 2000-3000mg / L, residual dyes, heavy metals, sulfur-containing compounds and various non-biodegradable substances in wastewater Organic additives are di...
