Abstract
The invention provides a sealed support device at the through-wall position of a header. The sealing performance can be guaranteed, the good thermal expansion performance is achieved, deformation between the through-wall position of the header and a boiler wall protection plate is avoided, supporting of the header is guaranteed, and efficient and safe operation of a boiler is guaranteed. The sealed support device comprises the header and the boiler wall protection plate. Connecting pipes are arranged outside the header after the header penetrates through the boiler wall protection plate, and an expansion joint is arranged at the position, corresponding to the boiler wall protection plate, of the outer side of the through-wall position of the header. The sealed support device is characterized in that the expansion joint is arranged on the header in a sleeved mode, the circular face of the inner end of the expansion joint is connected with the outer lateral face of the boiler wall protection plate in a welded mode, the inner annular face of a sealing steel plate is connected with the header in a welded mode, the inner end face of the sealing steel plate is connected with the circular face of the outer end of the expansion joint in a welded mode, the bottom of the sealing steel plate is supported on the upper end face of a support, the inner side of the support is connected with the outer lateral side of the boiler wall protection plate in a welded mode, and the support is located right below the through-wall position of the header.
Description
Technical field
The present invention relates to the technical field of boiler structure, be specially the sealed support device at a kind of header place through walls.
Background technology
Large coal powder boiler is often arranged in economizer, superheater header in flue, and header two ends pass from furnace wall backplate, and is drawn by several tube connectors.Header is worn furnace wall place should ensure sealing, thermal expansion problem, also will consider the support of header, and three will take into account.Existing header is set with expansion joint structure after running through furnace wall backplate, but does not fix the device of header fairlead, header is supported and have potential safety hazard, can not guarantee high efficiency boiler safe operation.
Summary of the invention
For the problems referred to above, the invention provides the sealed support device at a kind of header place through walls, it can ensure sealing, there is again good thermal expansivity, make can not deform between header place through walls and furnace wall backplate, guaranteed the supporting of header, guaranteed high efficiency boiler safe operation.
The sealed support device at a kind of header place through walls, its technical scheme is such: it comprises header, furnace wall backplate, described header has tube connector through its outer setting after described furnace wall backplate, described header has expansion joint with respect to the arranged outside of the position through walls of described furnace wall backplate, it is characterized in that: described expansion joint is set in described header, the inner disc of described expansion joint is welded to connect the lateral surface of described furnace wall backplate, the inner ring surface of sealing steel plate is welded to connect described header, the inner face of described sealing steel plate is welded to connect the outer end disc of described expansion joint, the bottom supporting of described sealing steel plate is in the upper surface of support, the inner side of described support is welded to connect the lateral surface of described furnace wall backplate, described support be positioned at described header place through walls under.
It is further characterized in that: the lateral surface of described sealing steel plate is welded with supporting steel plate, and the upper surface of described supporting steel plate is welded to connect the outer ring surface of described header, and the lower surface of described supporting steel plate is supported on the upper surface of described support;
