Description

Technical Field

[0001] The utility model relates to the technical field of ammonia decomposition equipment, in particular to energy-saving ammonia decomposition equipment. Background Art

[0002] The ammonia decomposition gas generator uses liquid ammonia as raw material. After vaporization, the ammonia is heated to a certain temperature. Under the action of the catalyst, the ammonia is decomposed into a hydrogen-nitrogen mixed gas. That is, under standard conditions, 1000 moles of ammonia can completely decompose to produce 44.8Nm3 of hydrogen-nitrogen mixed gas and absorb 11040 kcal of heat. That is, 1kg of liquid ammonia can completely decompose to produce 2.64m3 of hydrogen-nitrogen mixed gas. According to the chemical equation, the decomposed gas is composed of 75% H2 and 25% N2.

[0003] The existing device does not heat the liquid ammonia sufficiently during ammonia decomposition, resulting in slow ammonia liquid gasification. In addition, the existing stirring rod is an integrated structure. The stirring rod contacts and rubs with the material in the stirring container, which will cause the surface of the stirring rod to wear. As the surface of the stirring rod wears, its stirring efficiency may decrease, resulting in uneven stirring, affecting the uniformity of the final product. The worn stirring rod may release metal particles or other impurities, affecting the purity of the product. Therefore, those skilled in the art provide an energy-saving ammonia decomposition device to solve the problems raised in the above background technology. Utility Model Content
