Problems solved by technology

High-nitrate water is used as wastewater for primary brine production, and its discharge is not good for environmental protection. It is relatively difficult to deal with, and the treatment cost is high. If it can be fully reused, it will be of great significance to both production and environmental protection.

Embodiment Construction

[0015] Experiment 1: The present invention will be further explained by specific examples below:

[0016] In each example, the pH value of the high nitrate water was adjusted to 5, and then heated to 80°C and kept for 2 hours to quickly decompose the solid impurities (especially impurities like calcium carbonate) in the high nitrate water, and then proceed to gradient After cooling down (10℃ / min) to normal temperature (25℃), the high nitrate water is filtered through a device similar to a microfiltration membrane to remove a small amount of insoluble matter, and finally the treated high nitrate water can be obtained, and then deionized Water can be used as a dye accelerant after mixing in a certain proportion.

[0017] And the ratio of each component in the dye accelerator obtained in each example is shown in Table 1 (the unit of each content value in Table 1 is the mass concentration "g / L"):

Abstract

The invention relates to a novel comprehensive utilization process of taking sodium chloride and sodium sulfate in high liquid glauber salt produced by primary brine as accelerants for a dyeing and finishing process. The invention provides an accelerant for dyeing when high liquid glauber salt is taken as dye. The high liquid glauber salt processed by the method disclosed by the invention contains a few free ions such as calcium ions, iron ions and strontium ions, can achieve synergistic effect with basic dyeing accelerants of sodium sulfate and sodium chloride, so that the dyeing accelerating effect of the dyeing accelerants is greatly improved, and the dosage of the dyeing accelerants is reduced.

Description

Technical field [0001] The invention belongs to the field of inorganic chemical industry, and particularly relates to a new process for comprehensive utilization of sodium chloride and sodium sulfate in high nitrate water produced by primary brine production as a dye accelerator for dyeing and finishing processes. Background technique [0002] Printing and dyeing auxiliaries generally include printing auxiliaries and dyeing auxiliaries. Among them, the dyeing auxiliaries are divided into: dyeing agent, dispersing agent, leveling agent, fixing agent, fluorescent whitening agent, softening agent and so on. The present invention is one of the dyes, which is used to promote dye uptake, and is also called dye accelerant. [0003] Dye accelerator is a compound that can increase the dye uptake rate of the fiber, accelerate the dye uptake rate, reduce the dye content in the residual liquid, and obtain a higher dyeing depth. The dye-promoting effect is determined by the amount of dye-prom...
