Device and process for synthesizing diquat dichloride

The invention provides an aquacide dichloride synthesis device and process, and relates to the technical field of pesticide production. Comprising a first centrifugal pump, a mixing kettle, a second centrifugal pump, an HC276 reaction kettle, a third centrifugal pump, a first filter, a continuous layering tower, a layered organic phase storage tank, a fourth centrifugal pump, a layered mother liquor storage tank, a fifth centrifugal pump, a neutralization kettle, a sixth centrifugal pump, a new organic phase storage tank, a seventh centrifugal pump, a continuous extraction tower, an eighth centrifugal pump and an extracted organic phase storage tank. By adopting a continuous production method, the production efficiency is greatly improved, the process is simple, the solvent is convenient to recycle, and the requirement of reaction on equipment is not high, so that the problems that the equipment is seriously corroded, industrial production cannot be realized and the production cost is low due to the fact that
