Method and device for automatic-control continuous production of dye

Abstract

The invention discloses a method and a device for automatic-control continuous production of dye. The method comprises that raw materials are metered, are continuously fed into a tubular reactor and undergo a reaction and the products are discharged continuously. The device is characterized in that a reactor is provided with multiple reaction state detection devices; through multipoint automatic control, the reaction liquid obtained by the reaction is timely transferred to a next process; and abnormal materials in blending are timely pumped back to a blending kettle and then are re-blended. The method and the device realize accurate and automatic-control continuous production of dye, guarantee stable product quality, shorten production time, improve production efficiency, reduce a production cost, reduce three wastes, realize pollution and energy consumption reduction, and realize recycling economy and clean production.

Description

technical field

[0001] The invention relates to an automatic control continuous production method and device for dyes. Background technique

[0002] The dye industry is one of the industries with the longest history in the fine chemical industry. In recent years, with the development of my country's light textile industry, the dye industry has also developed rapidly; especially since the beginning of the new century, my country's dye industry has developed more rapidly, and its output, export volume and consumption have all ranked first in the world. However, at present, the production methods of dyestuffs in our country are still relatively backward, automatic control technology has not been applied in the dyestuff production process, and the comprehensive automation level of enterprises is generally low. Therefore, improving the level of automation in this field has always been an unremitting goal pursued by people in the industry.
