| titleOfInvention | Thiocarbazide Production System |
| abstract | The utility model provides a thiocarbazide production system, which belongs to the technical field of organic synthesis. The system includes a synthesis unit, a hydrogen sulfide absorption unit and a filtrate treatment unit. The synthesis unit includes a reaction device and a filter device, the reaction device is provided with a hydrazine hydrate feed pipe and a tail gas discharge pipe, and the filter device is provided with a filtrate outlet pipe. The hydrogen sulfide absorption unit includes a hydrogen sulfide absorption device, and the hydrogen sulfide absorption device is provided with an absorption liquid feed pipe. The filtrate processing unit includes a neutralization tank and a hydrazine hydrate distillation column. The feed end of the neutralization tank is connected to a filtrate outlet pipe. The top of the hydrazine hydrate distillation column is provided with a condensate recovery component, and the discharge end of the condensate recovery component is connected to hydrazine hydrate. feed tube. The column kettle of the hydrazine hydrate distillation column is provided with a waste water discharge pipe, and the waste water discharge pipe is connected to the absorption liquid feed pipe. By adopting the thiocarbazide production system, the conversion rate of hydrazine hydrate is improved, the sulfur-containing substances in the wastewater are recovered, the discharge amount of the wastewater is reduced, and clean production is realized. |
