A hexazinone crystallization reaction kettle

Abstract

The invention discloses a hexazinone crystallization reaction kettle, comprising a reaction kettle. A neutralization water-washing kettle is arranged on the right side of the reaction kettle. A desolvation kettle is arranged on the right side of the neutralization water-washing kettle. A crystallization kettle is arranged on the right side of the desolvation kettle. Stirrers are mounted on upper end surfaces of the reaction kettle, the neutralization water-washing kettle, the desolvation kettle and the crystallization kettle respectively. The hexazinone crystallization reaction kettle is simple in structure, clear and understandable in construction and convenient to use, and a product yield is high. Toluene can be effectively recovered through a toluene dehydration kettle and reutilized, atoluene-petroleum ether mixture solvent recovered by a distillation kettle can be fed into the desolvation kettle for reuse, and recovery of a plurality of solvents effectively reduces the productioncost. In addition, the stirrers in the reaction kettle, the neutralization water-washing kettle and the desolvation kettle accelerate mixing and reaction to increase the production efficiency. The stirrer in the crystallization kettle is used for breaking crystals, facilitating discharging. The hexazinone crystallization reaction kettle is high in degree of structure integration and simple to operate and deserves promotion.

Description

technical field [0001] The invention relates to the technical field of hexazinone production equipment, in particular to a hexazinone crystallization reaction kettle. Background technique [0002] Cyclopyrone is a systemic selective herbicide, which can be absorbed by plant roots and leaves, mainly through the xylem conduction, and has no harm to the roots of pine trees. It is an excellent forest herbicide. In the production process of cycloperone, a large amount of solvents such as toluene and petroleum ether are used. Toluene is a toxic chemical, which is harmful to the environment and the human body, so it cannot be discharged directly. The traditional cycloperone production device cannot Very good recovery of substances such as toluene, high production cost, not conducive to environmental protection, and the yield of cycloperone products obtained by the traditional cycloperone production process is low, and the production efficiency is low. Therefore, a crystallization r...

In the production process of cycloperone, a large amount of solvents such as toluene and petroleum ether are used. Toluene is a toxic chemical, which is harmful to the environment and the human body, so it cannot be discharged directly. The traditional cycloperone production device cannot Very good recovery of substances such as toluene, high production cost, not conducive to environmental protection, and the yield of cycloperone products obtained by the traditional cycloperone production process is low, and the production efficiency is low. Therefore, a crystallization reaction of hexazinone is needed kettle
