Abstract
The utility model relates to the technical field of synthetic ammonia equipment, in particular to a mixer and mixer bush assembly structure of a secondary reformer of a synthetic ammonia device, which comprises a mixer, a mixer bush, a mixer and a mixer bush clearance; the mixer is assembled in the mixer bushing, and a gap formed between the mixer and the mixer bushing after the mixer and the mixer bushing are assembled is a gap between the mixer and the mixer bushing (more than 6mm and less than or equal to 20 mm); and after the mixer and the mixer bushing are assembled in place, a gap formed at the end part of the upper side is sealed and welded. The assembly structure of the utility model enlarges the clearance between the mixer and the mixer bush, and the installation and maintenance equipment becomes simple and efficient; after the mixer is assembled in place, the gap at the upper part of the mixer is hermetically welded, so that the circulation of a medium in the gap is effectively cut off, the burning loss of the mixer, a mixer bushing and a refractory material at the position caused by the upward movement of flame at the lower part of the mixer is radically avoided, and the safety risk of operation is effectively reduced.
Description
Technical Field
The utility model relates to a synthetic ammonia equipment technical field, concretely relates to synthetic ammonia device two-stage reformer mixer and mixer bush package assembly.
Background
The mixer is arranged in the secondary reformer of the synthetic ammonia device, the mixer and the mixer bush are installed in a matching way, because the gap design of the mixer and the mixer bush in the prior secondary reformer is small, the problems of roundness, coaxiality and the like of a cylinder body in the manufacturing process are solved, the mixer is difficult to be smoothly assembled in the bush, the installation and maintenance difficulty is high, and the gap at the lower part of the mixer of the secondary reformer is combusted and moved upwards due to the fact that the prior mixer and the mixer bush are not provided with corresponding sealing design and measures after being assembled in place, a certain flow medium at the upper part of the mixer flows downwards through the gap between the mixer and the mixer bush, the flow rate of the medium in the gap is reduced, and the refractory materials at the position of the mixer of the secondary reformer are damaged, so that the safe long-period operation of the secondary reformer is seriously influenced. From this, the damage of different degrees all can appear in the normal operating in-process of equipment to blender, blender bush or even here refractory material in traditional two-stage conversion furnace, basically all will carry out the inspection and maintenance annually, and traditional blender and blender bush clearance design are less, and the installation is very difficult, and operation safety risk is higher.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects of the prior art, the utility model aims to provide a mixer of a secondary reformer of a synthetic ammonia device and a lining assembling structure of the mixer.
In order to achieve the above object, the utility model provides a following technical scheme:
a mixer and mixer bush assembly structure of a secondary reformer of a synthetic ammonia device comprises a mixer 1, a mixer bush 2, a mixer and mixer bush gap 3; the mixer 1 is assembled into a mixer bush 2, and a gap formed between the mixer 1 and the mixer bush 2 after the mixer 1 and the mixer bush 2 are assembled is a mixer and mixer bush gap 3; after the mixer 1 and the mixer bushing 2 are assembled in place, a gap 4 formed at the upper end is sealed and welded.
Further, the mixer and mixer bushing gap 3 is greater than 6mm and less than or equal to 20 mm.
Further, the diameter of an outer cylinder 5 of the mixer 1 is 480-505 mm.
Furthermore, the material for sealing and welding the gap 4 is ENiCrFe-2 or ENiCrFe-3.
Compared with the prior art, the utility model discloses an assembly structure possesses following beneficial effect:
the assembly structure of the utility model enlarges the clearance between the mixer and the mixer bush, and the installation and maintenance equipment becomes simple and efficient; after the mixer is assembled in place, the gap at the upper part of the mixer is welded in a sealing way, so that the circulation of media in the gap is effectively cut off, the burning loss of the mixer, a mixer bushing and refractory materials at the position caused by the upward movement of flame at the lower part of the mixer is fundamentally avoided, and the operation safety risk is effectively reduced.
