Portion's interface channel is connected to same vertical configuration floss hole after being connected.
This utility model is the further improvement to prior art, and it has simple in construction, uses easy to assembly, cost
Low, the features such as requirement on machining accuracy is low.
Accompanying drawing explanation
Fig. 1 is existing double tubesheet structural representation.
Fig. 2 is single tube plate side-looking structural representation of the present utility model.
Fig. 3 is single tube plate plan structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in detail: Fig. 2, shown in 3, one described in the utility model
The tube plate structure of space division steam heater, described space division steam heater includes the tube sheet 1, Yi Jiguan at housing, housing two ends
By the vertically arranged heat exchanger tube of heat exchange pore 23 on plate 1, the sidewall of housing is respectively arranged with dirty nitrogen inlet and outlet
And constitute dirty nitrogen shell side, the tube sheet 1 of both sides is respectively arranged with steam collection chamber and the import of connection heat exchanger tube 3 and goes out
Mouthful, and constitute water vapour tube side.The intermediate lateral of described tube sheet 1 is provided with at least Liang Tiao UNICOM and is in the upper heat exchange pore of same row
The grooved passageway 4 of 2, described at least two grooved passageway being arranged in parallel 4 can will may be leaked to shell side water with one after connection
The vertical configuration floss hole 5 that part is discharged in advance connects.
Being thought in figure, described heat exchanger tube 3 is fixed in the heat exchange pore 2 of tube sheet 1 by expanded joint and welding manner, in institute
State and the middle grooved passageway 4 of heat exchange pore 2 is provided with the leakage ring 6 being inserted in heat exchanger tube 3, wherein reveal the heat exchange pore 2 of ring 6
Inner side uses and is welded to connect, and reveals and uses expanded joint to connect outside the heat exchange pore 2 of ring 6；In described heat exchange pore 2 outside be with
The side of tube sheet grafting heat exchanger tube is inner side, and opposite side is outside.
Tube sheet 1 intermediate lateral described in the utility model is provided with at least two and is respectively communicated with horizontal be set with heat exchange in a row pore
The grooved passageway 4 of 2, and the both sides of every grooved passageway 4 are respectively communicated with respective side heat exchange pore 2, and at horizontal grooved passageway 4
One side end interface channel 7 is connected to same vertical configuration floss hole 5 after being connected.Described slit-like through-holes 4 cross section is square,
Can also be by circular or other shapes of hole shape.
Embodiment: the structure of tube sheet is mainly optimized by this utility model, Fig. 2, shown in 3, it uses in tube sheet
The all of mouth of pipe is coupled together by section with a passage, and the most all passages are pooled to a floss hole and discharge.This kind of structure pair
Than double tubesheet structure before, both saved raw-material two pieces of tube sheets, saved one section of heat exchanger tube the most accordingly；And heat exchanger tube
The most more convenient at welding and the expanded joint of tube sheet.
This utility model is connected by the form of expanded joint+welding to tube sheet and heat exchanger tube, uses welding before revealing ring
Connect, after suction ring, use the mode of expanded joint；The leakage of heat exchanger typically occurs in the weld of exchanger tubes and tubesheets, as even
Meeting place to reveal, vapor leakage to suction ring, temperature reduces, condenses into water, and due to pressure reduction, the steam condensing into water passes through
Outside space discharged by interface channel, thus avoids water vapour and leak into shell side, affects the performance of regeneration gas.
Length direction at each heat exchanger tube pore of tube sheet opens a leakage grooves, and every two excretion dew grooves will with a vast sky
Coupling together, the nearly terminal part at vast sky couples together with a vast sky, outside being guided to by interface channel with a pipe after allowing
Face.
Heat exchanger tube is first at entrance and the Tube-sheet Welding of tube side, and once welding place is revealed, steam by heat exchanger tube and
The gap of tube sheet enters reveals ring, and suction ring is followed by the expanded joint of exchanger tubes and tubesheets, and the comparison of patch is tight, and steam is due to pressure
The reason of difference, after entering interface channel, row is to floss hole, thus avoids steam leakage to the dirty nitrogen side of regeneration.
