Abstract
The utility model relates to a coal gas preheater of a tube furnace. The coal gas preheater of the tube furnace comprises a steam pipeline, and is characterized in that a guiding device is arranged at an inlet of the steam pipeline; the guiding device is vertical to the inlet of the steam pipeline; the length direction of the guiding device is parallel to the steam pipeline; the length of the guiding device is 200-500mm; and the section of the guiding device is arc, plate-shaped, or angular. Compared with the prior art, the coal gas preheater of the tube furnace has the advantage that the flowing direction of steam entering the preheater is controlled to uniformly disperse the steam, improve the heat exchanging efficiency of coal gas, reduce the impact of the steam on a coal gas pipeline, prolong the service life of a preheater pipeline and eliminate the safety hazard in the production.
Description
Technical field
The utility model relates to twin furnace double tower normal pressure tar continuous still battery field, relates in particular to a kind of tube furnace gas preheating device.
Background technology
The tar distillation operation generally all adopts traditional twin furnace double tower normal pressure tar continuous distillation process at present; Its weak point is directly to wash away the tube furnace interior conduit after steam gets into preheater; Not only steam distribution is uneven; Make the gas line heat exchange bad, also cause the pipeline local leakage easily, stay potential safety hazard.
Summary of the invention
The purpose of the utility model provides a kind of tube furnace gas preheating device, makes the steam homodisperse, improves heat exchange efficiency, reduces the impact of steam to pipeline, prolongs the preheater pipeline life-span.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
A kind of tube furnace gas preheating device comprises steam-pipe, and the steam inlet channel place is provided with liner, and said liner is perpendicular to steam inlet channel, and length direction is parallel with steam-pipe, length 200mm～500mm.
Said liner cross section is an arc.
Said liner cross section is a plate shape.
Said liner cross section is a dihedral.
Compared with prior art, the beneficial effect of the utility model is: control gets into the steam trend of preheater, makes the steam homodisperse; Improve the heat exchange efficiency of coal gas; Reduce the impact of steam, prolong the preheater pipeline life-span, eliminate the potential safety hazard in producing gas line.

Among the figure: 1-steam-pipe 2-gas line 3-steam inlet channel 4-liner
Embodiment
Be described further below in conjunction with the embodiment of accompanying drawing the utility model:
See Fig. 1; It is a kind of tube furnace gas preheating of the utility model device example structure synoptic diagram; Comprise steam-pipe 1, gas line 2, steam inlet channel 3 places are provided with liner 4, and liner 4 is perpendicular to steam inlet channel 3; Length direction is parallel with steam-pipe 1, length 200mm～500mm.
The cross-sectional shape of liner 4 can be multiple, as: see Fig. 2, the liner cross section is an arc.See Fig. 3, the liner cross section is a plate shape.See Fig. 4, the liner cross section is a dihedral, and its target is to make the dispersion effect of steam better, and other structure formations can also be arranged.
