Description
Technical field
The utility model relates to the location structures of comb in the vertical tube plates of a kind of superheater or reheater.
Background technique
Temperature is up to 650-1300 DEG C in the high-temperature flue of boiler furnace and boiler, the superheater to work under such conditions
Or the comb on the vertical tube plates of reheater is since by smoke-shock, vibration is very big, and easily deformed damaged.In order to solve this
The limited block of a strip usually is respectively welded to enhance the impact resistance of heat exchanger tube, but this in pipe row two sides in the industry in one problem
Kind structure usually occurs causing heat exchanger tube drawing crack because heat exchanger tube is different from the thermal expansion amount of limited block on tube panel under high temperature environment
Situation, thus to the operation of equipment generate strong influence.
Utility model content
Technical problem to be solved in the utility model is：There is provided a kind of can fix hanging down for superheater or reheater well
Straight tube screen, the location structure for preventing vertical tube plates from deforming because of impact and itself comb will not be made drawing crack problem occur.
In order to solve the above technical problems, technical solution used by the utility model is：A kind of superheater or reheater
The location structure of comb in vertical tube plates, including the connector sleeve being set on comb on each heat exchanger tube, one end of connector sleeve with
Heat exchanger tube mutually welds, and is equipped at least one positioning component outside comb at connector sleeve, and positioning component includes two and is respectively set
In several horizontal connectors of two locating pieces of locating piece and connection of comb two sides, locating piece includes upper and lower two limited blocks,
It is connected between upper and lower two limited blocks by perpendicular connector, positioning component is placed in setting even by the limited block of its top and the bottom
In the supporting block of female connector outer lower portion, half matched with connector sleeve is equipped in the position for corresponding to each connector sleeve on limited block
Gap is equipped between the semi-circular recesses of circular groove, connector sleeve and limited block.
As a preferred solution, adjacent when being equipped with more than two positioning components outside the comb at connector sleeve
It is connected between positioning component by swivel pin.
As a preferred solution, every group of positioning component is for positioning 5-10 root heat exchanger tube.
As a preferred solution, the gap between the connector sleeve and the semi-circular recesses of limited block is greater than 1mm.
As a preferred solution, the perpendicular connector is junction steel plate.
As another preferred scheme, the perpendicular connector is several connecting rods.
As a preferred solution, the horizontal connector includes several erections and is welded on above two top limited blocks
Steel bar and several erections and the steel bar that is welded below two lower limit blocks.
The utility model has the beneficial effects that：This location structure greatly strengthens the impact resistance of tube panel, and due to fixed
It is active connection state between hyte part and heat exchanger tube, the rising-heat contracting-cold that positioning component will not exchange heat pipe has an impact, so that changing
The problem of heat pipe is not in drawing crack.
Since one end of connector sleeve is mutually welded with heat exchanger tube, connector sleeve is avoided to cause from heat exchanger tube because thermal expansion amount is different
Junction drawing crack, greatly improves the safety of use；
When due to being equipped with more than two positioning components outside comb at connector sleeve, adjacent positioned inter-module is by swivel pin phase
Connection so that the freedom degree of heat exchanger tube dilatancy is higher, even if so that the heat exchanger tube in tube panel be hit and thermally expand after not
In the same plane, this positioning component remains to play positioning action, and heat exchanger tube is avoided to damage because of this deformation.
Since the gap between connector sleeve and the semi-circular recesses of limited block is greater than 1mm, so that deformation and the position of heat exchanger tube
It is bigger to move space, so that heat exchanger tube is less likely to be damaged.
