Abstract
The invention discloses a tube clamp device of an inverted U-shaped bent tube panel of a high-temperature reheater. The Inverted U-shaped bent part at the front part of a 600MW-grade supercritical boiler introduced by the Harbin Boiler Company Limited in early period is positioned inside a boiler, due to the relatively small wall thickness of a reheater tube, cracks are formed on a lifting plate under the overlapping action of various factors, and tube explosion also happens, so that the normal operation of the boiler is seriously influenced. The tube clamp device comprises tube clamps (1), wherein each tube clamp is formed by abutting a pair of symmetric mold plates; the mold plates are provided with a pair of semi-circular grooves in parallel; the abutted mold plates are connected together in a plug welding mode; the plug welding position is on a planar part between the semi-circular grooves; inverted U-shaped high-temperature reheater tubes (2) which are lifted above a hearth roof penetrate through the circular cavity which is formed among the abutted semi-circular grooves; the tube clamps are welded with a hanging plate (3). The tube clamp device is used for suspending a high-temperature reheater panel tube.
Description
technical field:
the present invention relates to a kind of high temperature reheater inverted U bend pipe screen pipe collar device.
background technology:
the inverted U-shaped crook of anterior tube panel is in stove again for the early stage 600MW grade super critical boiler height of introducing of Harbin Boiler Plant, and because reheater pipe wall thickness is less, under the superposition of various factors, crackle appears in boatswain chair, and booster has occurred.Having a strong impact on boiler normally moves.
summary of the invention:
the object of this invention is to provide a kind of high temperature reheater inverted U bend pipe screen pipe collar device.
above-mentioned object realizes by following technical scheme:
a kind of high temperature reheater inverted U bend pipe screen pipe collar device, its composition comprises: pipe collar, described pipe collar is formed by a pair of symmetrical template docking, described template has one group of parallel semi-circular recesses, the template of described docking connects by plug welding, the planar section of described plug welding position between described semi-circular recesses, is raised to the circle that more than burner hearth ceiling inverted U-shaped high temperature reheater pipe forms through the semi-circular recesses docking by described aerial, and described pipe collar and hanging board weld.
described high temperature reheater inverted U bend pipe screen pipe collar device, the described described pipe collar of inverted U-shaped high temperature reheater Guan Yuyi group connects.
beneficial effect:
more than the present invention brings up to ceiling the inverted U-shaped bend pipe screen of the anterior tube panel of high temperature reheater, and original connection end plate is changed into pipe collar connection.In the present invention, because pipe collar and pipe do not weld, make the swollen difference of pipe way can access release, pipe can radially move freely in pipe collar, thereby pipe collar is not easy pipe to produce stress, eliminated the various factors that produces stress, guaranteed that pipe can not crack, there is not pipe explosion accident, guarantee this parts safe operation.Guaranteed that boiler normally moves.The present invention is applicable to the inverted U-shaped kinking structure of super critical boiler high temperature reheater tube panel, prevents booster.All parts all adopt stainless steel material.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present invention.
accompanying drawing 2 is plug welding schematic diagrames of pipe collar of the present invention and pipe.In figure, 4 is plug welding hole.
accompanying drawing 3 is side views of accompanying drawing 3.
the specific embodiment:
embodiment 1:
a kind of high temperature reheater inverted U bend pipe screen pipe collar device, its composition comprises: pipe collar 1, described pipe collar is formed by a pair of symmetrical template docking, described template has one group of parallel semi-circular recesses, the template of described docking connects by plug welding, the planar section of described plug welding position between described semi-circular recesses, be raised to the circle that more than burner hearth ceiling inverted U-shaped high temperature reheater pipe 2 forms through the semi-circular recesses docking by described aerial, described pipe collar and hanging board 3 weld.
embodiment 2:
according to the high temperature reheater inverted U bend pipe screen pipe collar device described in embodiment 1, the described described pipe collar of inverted U-shaped high temperature reheater Guan Yuyi group connects.
Claims (2)
1. a high temperature reheater inverted U bend pipe shields pipe collar device, its composition comprises: pipe collar, it is characterized in that: described pipe collar is formed by a pair of symmetrical template docking, described template has one group of parallel semi-circular recesses, the template of described docking connects by plug welding, the planar section of described plug welding position between described semi-circular recesses, be raised to the circle that more than burner hearth ceiling inverted U-shaped high temperature reheater pipe forms through the semi-circular recesses docking by described aerial, described pipe collar and hanging board weld.
