Description

Technical Field

[0001] The utility model relates to the technical field of smelting waste heat boilers, and more specifically to a membrane wall shock absorbing device for smelting waste heat boilers. Background Art

[0002] Boiler membrane wall refers to the furnace wall of a boiler welded with tubes and fins. Large boiler water-cooled walls are basically membrane walls, which have the advantages of simplicity and saving steel. For insulation, it is only necessary to lay silicate insulation materials outside the furnace, without building refractory brick walls. It expands evenly and has high thermal efficiency. In order to recycle the waste heat from smelting, a boiler membrane wall will be set on the outside of the smelting furnace, and the fluid inside the tube will be used to absorb the waste heat from smelting, and the fluid will be used to export the waste heat to the outside for use.

[0003] After searching, the existing patent (publication number: CN214946022U) discloses a smelting waste heat boiler membrane wall shock absorption device. When in use, the fixed plate is connected and installed with the external boiler frame vertical beam, and then the arc-shaped top block at the front end of the shock-absorbing shaft is pressed against the tube of the membrane wall. Under the joint action of spring A and spring B, the shock-absorbing shaft supports and absorbs shock to the tube on the membrane wall, and at the same time reduces the shaking of the membrane wall body when in use, thereby increasing the service life of the membrane wall. However, in the process of realizing the utility model, the inventor discovered that the prior art had the following problems: when the arc-shaped top block is used, the vertical position of the arc-shaped top block is fixed. For boiler membrane walls of different specifications, the vertical spacing of multiple arc-shaped top blocks in the prior art is the same, which is difficult to adapt to different pipe spacing densities. In addition, the arc-shaped top blocks in the prior art are in the same vertical plane. When the boiler membrane wall is in an inclined state, it is difficult to fit with the boiler membrane wall. Therefore, the overall shock-absorbing device has the defect of poor adaptability, and it is difficult to meet the use of boiler membrane walls with different pipe spacings and pipe inclinations.

[0004] To this end, the utility model proposes a boiler membrane wall shock-absorbing device which has low installation difficulty and strong adaptability. Utility Model Content
