System and method for continuously producing ammonium glyphosate granules

Abstract

The invention discloses a system for continuously producing ammonium glyphosate granules. The system comprises a high-speed coulter reactor provided with a feed port, a heating device, a first induceddraft fan and a discharge port, a material distribution bin with the feed port being connected with a discharge port of the high-speed coulter reactor, a granulator with the feed port being connectedwith a discharge port of the material distribution bin, a material uniform distributor with the feed port being connected with a discharge port of the granulator,, a microwave dryer with the feed port being connected with a discharge port of the material uniform distributor, wherein the microwave dryer is provided with a second induced draft fan, a flexible crusher with the feed port being connected with a discharge port of the microwave dryer, a vibrating screen classifier with the feed port being connected with a discharge port of the flexible crusher, and a filter cartridge dust remover with the feed port being respectively connected with a discharge port of the first induced draft fan and a discharge port of the second induced draft fan. The system is high in production efficiency andgood in product quality, and can solve the problems of high energy consumption, unsatisfactory occupational health environment, high tail gas treatment operation cost, high later environment-friendlywastewater treatment cost and the like in the existing glyphosate granule production process.

Description

technical field [0001] The invention relates to the technical field of preparation of pesticide preparations, and more specifically relates to a system and method for continuous production of glyphosate ammonium salt granules. Background technique [0002] Glyphosate ammonium salt granule is a broad-spectrum herbicide, and it is one of the glyphosate series preparations. It can be formulated into various specifications of glyphosate ammonium salt granule products according to different formulations. [0003] Since the industrial production of ammonium glyphosate granules has been realized, many improvements have been made at home and abroad around the design of ammonium glyphosate granules production equipment, reaction conditions, cost reduction, and efficiency improvement, and some achievements have been made. There are two main production processes of ammonium glyphosate granules in the market: [0004] (1) Solid-state aging method glyphosate ammonium salt granule proces...

AI Technical Summary

Problems solved by technology

[0015] In view of this, the purpose of the present invention is to address the deficiencies in the prior art and to meet the needs of reality, to provide a system and method for continuous production of glyphosate ammonium salt granules, aiming to solve the problem of glyphosate in the existing solid-state kneader method. Product quality problems existing in the phosphonium ammonium salt granule process, improve production efficiency, and at the same time solve the problems of high energy consumption, unsatisfactory occupational health environment, high operating cost of tail gas treatment, and environmental protection in the later stage in the two commonly used glyphosate granule production processes Problems such as high waste water treatment costs to improve reaction efficiency and reduce energy consumption
