Ammonia charging method for solid ammonia storage tank

Abstract

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 recording is conducted. By the adoption of the ammonia charging method for the solid ammonia storage tank, ammonia charging time can be shortened, the ammonia charging speed is increased, ammonia charging efficiency is improved, and ammonia charging quality is guaranteed.

Description

technical field [0001] The invention relates to an ammonia charging method for a solid ammonia storage tank, belonging to the technical field of automobile tail gas treatment systems. Background technique [0002] With the progress of the economy and society, the rapid development of the automobile industry, the number of automobiles has increased sharply, and the environmental pollution caused by automobile exhaust has become increasingly serious. Therefore the purification problem of automobile tail gas, is subjected to people's attention day by day. [0003] The automobile exhaust gas treatment system stores ammonia gas in solid particles and releases it when needed, and removes NOx hazards after reacting with the catalyst, which has achieved the purpose of purifying the exhaust gas. The method is safe, reliable, low in cost and long in cruising range. [0004] However, during the ammonia filling process of the solid ammonia storage tank, there are situations such as lo...
