The invention discloses an energy-saving and efficiency-improving urea production system. The system comprises a synthesis unit, a hydrolysis analysis unit, an evaporation granulation unit and a circulating absorption unit, the method has the advantages that through full-tower operation transformation of the synthetic tower and additional arrangement of the tower plates, idle space in the tower is fully utilized, the material reaction time is prolonged, the urea synthesis conversion rate is remarkably improved, the unreacted material amount is reduced, and the circulating load is reduced, so that the raw material feeding amount can be increased, the capacity of the device is greatly improved, and the problem that the capacity of a traditional process is limited is solved; and sufficient fertilizer guarantee is provided for grain production. The waste heat of 98 DEG C hydrolysis water purification of the hydrolysis system is used for preheating liquid ammonia, energy waste caused by the fact that waste heat is cooled through circulating water in a traditional process is avoided, consumption of extra energy for liquid ammonia preheating is reduced, gradient utilization of heat is achieved, steam consumption and circulating water consumption of the device are remarkably reduced, and the energy-saving effect is outstanding.
