Ammonia charging method for solid ammonia storage tank

The invention relates to an ammonia charging method for a solid ammonia storage tank. The ammonia charging method for the solid ammonia storage tank is characterized by comprising the steps that an ammonia source is gasified at the preset temperature of 50-60 DEG C through a liquid ammonia evaporation system so as to reach the preset pressure of 0.5-0.8 MPa; air in the solid ammonia storage tank is exhausted through a vacuum pump, so that the preset vacuum degree of 0.07-0.09 MPa is reached; the solid ammonia storage tank is placed on a mixing vibration machine through special hoisting equipment to be vibrated, or the solid ammonia storage tank is placed on a standing rack to stand; a coolant pipeline is connected to the outside of the solid ammonia storage tank, and the coolant temperature is kept between 10 DEG C and 15 DEG C; and the solid ammonia storage tank is connected with an ammonia pipeline, ammonia charging is started, weighing is conducted after ammonia charging is conducted for 20-25 hours, and r
