Method for recovering condensed fluid of glyphosate synthesis solution

Abstract

The invention discloses a method for recovering a condensed fluid of a glyphosate synthesis solution. Glyphosate technical wet powder enters into a main drying tower for drying through a feeding device and enters into a cyclone drying tower for drying to obtain qualified glyphosate technical. The method is characterized in that the material from the cyclone drying tower enters into a cyclone separator, the powder separated by the cyclone separator reenters into the main drying tower under the action of a fan to be mixed with the glyphosate technical wet powder in the main drying tower, and the mixture is dried. According to the method, the low-content powder with high premium grade rate is returned into the main drying tower to be mixed with the wet powder and the mixture is dried by adopting the high-pressure fan and a stainless steel air pipe, so that the powder is uniformly dispersed in the glyphosate technical for packaging. Therefore, the premium grade rate of the glyphosate technical is increased by 2%, the recovery rate of the technical is more than 99.9%, the powder is greatly reduced, the production environment is optimized, and the loss of steam and the like is reduced by 20% year on year.

Description

Technical field [0001] The invention relates to the technical field of glyphosate production, in particular to a method for returning powder material to a production system during the drying process of glyphosate original medicine to be mixed into a qualified glyphosate original medicine. Background technique [0002] At present, the drying method of glyphosate raw medicine is generally used in the process of heat exchange air with steam heat exchanger, and then hot air is blown into the main drying tower through a blower, and the wet glyphosate powder is blown by the hot cyclone in the main drying tower. Begin to blow into the cyclone drying tower, and discharge the material at the bottom of the cyclone drying tower to obtain qualified glyphosate technical medicine. The hot cyclone at the top of the tower carries low-content and high-grade powders and is drawn into the cyclone for separation. 器中. The glyphosate powder is obtained by discharging the material at the bottom of the ...

AI Technical Summary

Problems solved by technology

In this production process, although the powder recovered from the bottom of the cyclone separator has a high rate of high-quality products, it cannot be sold as a qualified glyphosate technical drug due to its insufficient glyphosate content, and can only be sold at a low price or made into a microscopic profit. The glyphosate aqueous solution is sold, all of which lead to high energy consumption, waste of raw materials, low production capacity and low yield of the glyphosate technical drying process
