Description

Technical Field

[0001] The utility model relates to the technical field of ammonia decomposition, in particular to a detachable ammonia decomposition device. Background Art

[0002] Most of the existing nitrogen is obtained by the production side through the decomposition of liquid ammonia by ammonia decomposition equipment. Ammonia decomposition refers to the chemical reaction of decomposing ammonia into nitrogen and hydrogen. Ammonia decomposition is an endothermic reaction and energy is required to start the reaction. The ammonia decomposition gas generator uses liquid ammonia as raw material, heats the ammonia to a certain temperature after vaporization, and decomposes the ammonia into a hydrogen-nitrogen mixed gas under the action of the catalyst.

[0003] In the long-term ammonia decomposition process of the existing ammonia decomposition equipment, ammonia scale is easy to form on the inner wall of the decomposition equipment. The ammonia scale attached to the inner wall will affect the subsequent ammonia decomposition and the decomposition efficiency. In addition, the top cover of the existing ammonia decomposition equipment is usually connected by bolts through threads, which is not convenient to disassemble, resulting in great trouble in the maintenance of the interior and inconvenience in maintenance, which will affect the service life of the decomposition equipment.
