Description
Technical field
The utility model relates to boiler plant field, is especially a kind of pendant superheater steam trap connection.
Background technology
In recent years, the outstanding advantages such as CFBB is wide with its fuel tolerance, pollutant emission is low, cost of investment is low obtain and develop rapidly.Along with big-and-middle-sized high-temperature high-pressure boiler comes into the market, adopt in burner hearth and arrange that the structure of pendant superheater also becomes a kind of necessary.
Be arranged in pendant superheater in burner hearth because of working medium side (superheated steam) temperature higher, swell increment is large, and in boiler operatiopn, the vibration of tube panel is violent, and its steam trap connection has also occurred some problems in design and running.As shielded the hydrophobic base of header directly with hydrophobic header welding, cause expanding not, tube panel vibration is violent, and commissure easily produces larger fatigue stress, and these reasons all easily cause weld bond to ftracture.
Summary of the invention
The utility model object is to solve the problem, and provides a kind of pendant superheater steam trap connection, is specifically realized by following technical scheme:
A kind of pendant superheater steam trap connection, be connected with some hydrophobic outlet of shielding header, comprise and be positioned at the hydrophobic header in right side that header drain pipe was shielded in some left sides, header drain pipe was shielded on some right sides, be positioned at the hydrophobic header in left side on the left of boiler and be positioned on the right side of boiler, be distributed in shielded on the left of header, the hydrophobic outlet on right side shielded header drain pipe respectively by left side, right side was shielded header drain pipe and is communicated with the hydrophobic header in right side, the hydrophobic header in left side.
Described pendant superheater steam trap connection, it designs further and is, header drain pipe was shielded in left side, right side was shielded header drain pipe and is formed by connecting by the drain pipe straight section being positioned at two expansion bends and connection two expansion bends.
Described pendant superheater steam trap connection, it designs further and is, the hydrophobic header in described left side, the hydrophobic header in right side are all horizontally disposed with, and both are in boiler both sides sustained height; And stagger mutually before and after the hydrophobic header in described left side, the hydrophobic header in right side, the diameter length of distance for described drain pipe straight section that stagger between the two.
Described pendant superheater steam trap connection, it designs further and is, header drain pipe was shielded in described left side, header drain pipe was shielded on right side six respectively, and correspondingly, the hydrophobic header in described right side, the hydrophobic header in left side have six interfaces respectively.
Drain water piping is optimized transformation by the utility model in limited space, by the method for interlaced arrangement, effectively add the expansion distance of steam trap connection, decrease the fatigue stress that tube panel vibration butt welded seam produces, the leakage hidden danger caused thus elimination weld bond ftractures.
Accompanying drawing explanation
Fig. 1 is example structure schematic diagram of the present utility model.
Fig. 2 is left view embodiment illustrated in fig. 1.
Detailed description of the invention
Below in conjunction with Figure of description and embodiment, the utility model is further described.
As shown in Figure 1, this pendant superheater steam trap connection is connected with some hydrophobic outlet of shielding header 5, comprise and be positioned at the hydrophobic header in right side that header drain pipe 1 was shielded in some left sides, header drain pipe 2 was shielded on some right sides, be positioned at the hydrophobic header in left side on the left of boiler and be positioned on the right side of boiler, be distributed in shielded on the left of header, the hydrophobic outlet on right side shielded header drain pipe respectively by left side, right side was shielded header drain pipe and is communicated with the hydrophobic header in right side 4, the hydrophobic header 3 in left side.
Particularly, header drain pipe was shielded in left side, right side shielded header drain pipe and be welded by being positioned at two expansion bends 12 and connecting the drain pipe straight section 11 of two expansion bends.
As shown in Figure 2, the hydrophobic header in left side, the hydrophobic header in right side are all horizontally disposed with, and both are in boiler both sides sustained height; And stagger mutually before and after the hydrophobic header in left side, the hydrophobic header in right side, the diameter length of distance for drain pipe straight section that stagger between the two, this structure takes up room less, thus is easy to transform existing corresponding construction.
Header drain pipe was shielded in left side, header drain pipe was shielded on right side six respectively, and correspondingly, the hydrophobic header in right side, the hydrophobic header in left side have six interfaces respectively.
Drain water piping is optimized transformation by the utility model in limited space, by the method for interlaced arrangement, effectively add the expansion distance of steam trap connection, decrease the fatigue stress that tube panel vibration butt welded seam produces, the leakage hidden danger caused thus elimination weld bond ftractures.
