Abstract
The invention relates to a smoke air duct sealing structure and a sealing method. At present, the sealing devices of conventional construction can only absorb large expansion differences perpendicular to the flue skirt. With the continuous improvement of boiler form, the sealing structure at some parts needs to absorb larger expansion difference parallel to the flue. The original structure has been unable to meet the current requirements. A novel flue gas duct sealing structure, the composition of which comprises: two side guard plates (1), a main backplate (2), reinforcing plate (3), upper seal plate (4) and lower seal plate (5), two side guard plates are connected with the main backplate, and side guard plate and main backplate are by last "omega" bent plate (6), and sealed steel sheet, lower "omega" bent plate (7) are constituteed, have seted up on the main backplate and have worn flue structure (8), and the unsealed department of main backplate and side guard plate upper end adopts upper seal plate and lower seal plate to seal up. The invention is applied to the field of boiler flue gas ducts.
Description
The technical field is as follows:
the invention relates to a novel smoke and air duct sealing structure and a sealing method.
Background art:
when the pipeline or the steel beam penetrates out of the flue, the sealing structure of the penetrating part needs to be considered on the flue. Because the thermal expansion value of the penetrating part is different from the expansion value of the flue, the sealing device needs to consider to absorb the expansion difference between the penetrating part and the flue, and the safe operation of the flue and the penetrating part is ensured.
The sealing means of conventional construction can only absorb large expansion differences perpendicular to the flue skirt. With the continuous improvement of boiler form, the sealing structure at some parts needs to absorb larger expansion difference parallel to the flue. The original structure has been unable to meet the current requirements.
The invention content is as follows:
the invention aims to provide a novel smoke channel sealing structure and a sealing method.
The above purpose is realized by the following technical scheme:
a novel flue gas duct sealing structure, the composition of which comprises: the side guard plates are connected with the main guard plate, the side guard plates and the main guard plate are composed of upper omega-shaped bent plates, sealing steel plates and lower omega-shaped bent plates, a flue penetrating structure is formed in the main guard plate, the main guard plate and the unsealed part of the upper end of the side guard plate are sealed and welded through the upper sealing plate and the lower sealing plate, the reinforcing plates are arranged at the stress part of the smoke air duct sealing structure, and the upper sealing plate and the lower sealing plate are of a parallel structure.
The novel flue duct sealing structure is characterized in that a sealing steel plate of the main guard plate is grooved according to the appearance of the penetrating structure and welded with the penetrating flue structure.
The novel flue duct sealing structure is characterized in that one side of the side guard plate is welded on the flue guard plate, and the other side of the side guard plate is welded with the edge of the main guard plate.
The novel flue duct sealing structure is characterized in that two sides of the main guard plate are welded with the side guard plates, and the sealing plate of the main guard plate is welded with the flue penetrating structure.
The sealing method of the novel flue duct sealing structure comprises the following steps:
when the flue is heated and expands downwards, the beam penetrating through the flue is fixed in the external environment, so that the flue expands downwards, and the beam penetrating through the flue is fixed; so that the upper omega-shaped bent plate of the sealing device is pressed to deform, and the lower omega-shaped bent plate is stretched to deform. The whole sealing device absorbs the relative displacement of the upper omega-shaped bent plate and the lower omega-shaped bent plate caused by the expansion difference by means of the forced deformation of the upper omega-shaped bent plate and the lower omega-shaped bent plate.
The invention has the beneficial effects that:
1. the invention can meet the new arrangement form of the boiler, can absorb a larger expansion difference value parallel to the flue guard plate at a specific part, and ensures the safe and reliable operation of the flue and the penetrating part.
The present invention improves the layout problem of one type of boiler. Making possible the implementation of the arrangement of the boiler. The structure absorbs larger expansion difference values parallel to the flue guard plate, and the safe and reliable operation of the flue and the penetrating parts is ensured. The new structure is successfully used in the Rehmu mountain polder project in Hainan. And the method can be popularized and applied in subsequent similar structures.
