Abstract
Novel circulating fluidized bed separator tube panel and upper portion annular header connection structure. The connecting position of the tube panel and the upper annular header of the cyclone separator of the circulating fluidized bed boiler is that the upper part of the tube panel is butted with the annular header in a horizontal plane, and when the tube panel and the annular header are combined on site, the lower half parts of all welded junctions are in overhead welding, and the space is narrow, so that the welding is not facilitated. The utility model discloses a constitution includes: annular collection case (1) and separator tube panel (2), annular collection case lower part evenly arranged a set of coupling (3), the coupling arrange down, separator tube panel upper portion arranged a set of 90 degrees elbows (4), 90 degrees elbows for buckling into 90 degrees pipes, annular collection case with separator tube panel butt joint face be perpendicular butt joint. The utility model particularly relates to a novel circulating fluidized bed separator tube panel and upper portion annular collection case connection structure.
Description
Technical Field
The utility model relates to a boiler equipment, concretely relates to novel circulating fluidized bed separator tube panel and upper portion annular collection case connection structure.
Background
The connection position of the tube panel and the upper annular header of the cyclone separator of the circulating fluidized bed boiler is that the upper part of the tube panel is butted with the annular header in a horizontal plane, and when the tube panel and the annular header are combined on site, the lower half parts of all welded junctions are in overhead welding, and the space is very narrow, so that the tube panel and the annular header are not beneficial to welding. The fin adjustment needs to be cut when the building site is to the mouth, but the very narrow space that can adjust of fin between the pipe is limited, and damages the pipe easily when the cutting, requires the installation to have certain level, otherwise will cause the hidden danger to the unit operation, influences installation quality and installation effectiveness simultaneously.
Disclosure of Invention
The utility model aims at providing a novel circulating fluidized bed separator tube panel and upper portion annular collection case connection structure.
The above purpose is realized by the following technical scheme:
the utility model provides a novel circulating fluidized bed separator tube panel and annular collection case connection structure in upper portion, its constitution includes: the annular header and the separator tube panel, annular header lower part evenly arranged a set of coupling, the coupling arrange down, separator tube panel upper portion arranged a set of 90 degrees elbows, 90 degrees elbows for buckling into 90 degrees pipe, annular header with separator tube panel butt joint face be the perpendicular butt joint.
The novel circulating fluidized bed separator tube panel and the upper annular header connecting structure are characterized in that no fin is arranged between the 90-degree elbows.
Has the advantages that:
1. the utility model relates to a circulating fluidized bed separator tube panel and upper portion annular collection case connection structure increases perpendicular ascending 90 degrees elbows in former separator tube panel and annular collection case butt joint position, changes the coupling of upper portion annular collection case into and arranges down, guarantees pipe horizontal direction and the straight section length of vertical direction simultaneously, need not weld fin between the horizontal direction of increase and the vertical direction pipe.
2. Separator tube panel and last header crate weld joint are whole to become horizontal welding, do not have the narrow and small position that needs to weld up in space, interval grow between the pipe, adjustable space grow, and furthest's assurance welding is to mouthful quality, does not have the fin between the 90 degrees elbows, and the phenomenon of having avoided cutting fin accidental injury pipe when adjusting to mouthful takes place, improves on-the-spot installation effectiveness and installation quality, reduces the expense that the disappearance produced, practices thrift the cost.
Description of the drawings:
FIG. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a top view of FIG. 1;
FIG. 3 is a schematic view of a conventional connection between a separator tube panel and an annular header;
FIG. 4 is a top view of FIG. 3;
FIG. 5 is a schematic perspective view of the present invention;
in the figure: 1. annular header, 2, separator tube panel, 3, coupling, 4, 90 degrees elbows.
The specific implementation mode is as follows:
example 1:
the utility model provides a novel circulating fluidized bed separator tube panel and annular collection case connection structure in upper portion, its constitution includes: annular collection case 1 and separator tube panel 2, annular collection case lower part evenly arranged a set of coupling 3, the coupling arrange down, separator tube panel upper portion arranged a set of 90 degrees elbows 4, 90 degrees elbows for buckling into 90 degrees pipes, annular collection case with separator tube panel butt joint face be the perpendicular butt joint.
Example 2:
according to the novel connecting structure of the tube panel and the upper annular header of the circulating fluidized bed separator in the embodiment 1, no fin is arranged between the 90-degree elbow.
Claims (2)
1. The utility model provides a novel circulating fluidized bed separator tube panel and annular collection case connection structure in upper portion, its constitution includes: annular collection case and separator tube panel, characterized by: the lower part of the annular header is uniformly provided with a group of pipe joints, the pipe joints are arranged downwards, the upper part of the separator pipe screen is provided with a group of 90-degree elbows, the 90-degree elbows are pipes bent into 90 degrees, and the butt joint surfaces of the annular header and the separator pipe screen are vertically butted.
2. The new circulating fluidized bed separator tube panel and upper annular header connection structure of claim 1, wherein: no fins are arranged between the 90-degree elbows.
