Problems solved by technology

[0002] The existing urotropine distillation system is equipped with 2 condensate intermediate tanks, which are connected with 2 hydraulic jet vacuum pumps. After the water vapor from the distillation kettle is condensed by the condenser, the condensed water and condensed gas are separated in the condensate tank. The non-condensable gas is sucked away by the vacuum pump. After the condensed water in the middle tank reaches a certain liquid level, the distillation is stopped. After the vacuum is removed, the condensed water is discharged to the collection tank. Distillation is not only inconvenient to operate, but also affects the dehydration capacity of the system, which in turn affects the overall water balance of production
