Fig. 2 is top view of the present utility model；
In figure：1. outer cylinder body, 2. regeneration tank cylinder, 3. cofferdam upper port horizontal line, 4. downflow weir, 5. overflow launder, 6. overflows
Its bottom plane, 7. Recycling Mother Solution pipe, 8. foamed pipe, 9. jet ejectors, 10. cofferdam bottom minimum point.
Specific embodiment
The utility model is further described presently in connection with accompanying drawing.Accompanying drawing be simplified schematic diagram only in a schematic way
Basic structure of the present utility model is illustrated, therefore it only shows the composition relevant with the utility model.
It is structural representation of the present utility model referring to Fig. 1, as illustrated, the coke-stove gas one of the present embodiment is tower de-
Sulphur top of tower regeneration tank downflow weir, including outer cylinder body 1 and regeneration tank cylinder 2, the bottom of outer cylinder body 1 and the middle and lower part of regeneration tank cylinder 2
Connection；The side of outer cylinder body 1 is connected with foamed pipe 8, and opposite side is connected with Recycling Mother Solution pipe 7；20- is provided with the top cover of outer cylinder body 1
30 groups of jet ejectors 9, the through bottom of regeneration tank cylinder 2 in the inside of the insertion of injector 9 outer cylinder body 1；The upper end of regeneration tank cylinder 2
Overflow launder 5 is provided with, its bottom is connected respectively with outer cylinder body 1 and the bottom of downflow weir 4；The upper end 700mm-800mm of regeneration tank cylinder 1
Place is provided with downflow weir 4 (away from cofferdam minimum point 10), and downflow weir 4 is centroclinal to regeneration tank cylinder 2.
In prior art designs, most of regeneration tank cell body and cofferdam are upper next overall, generally one circular cylinder
Body, is 90 ° of angles with horizontal plane.Embodiment of the present utility model makes regeneration tank cylinder 2 and horizontal plane angle or 90 ° into, but
It is that downflow weir 4 is separated with regeneration tank cylinder 2, the minimum point of downflow weir 4 is 700- away from the top vertical range of regeneration tank cylinder 2
800mm；One necking to the center of regeneration tank cylinder 2, regeneration tank downflow weir 4 and isopipe root plane 6 are arranged at the top of downflow weir 4
Angle is about 56 °；Overflow launder 5 is ring-shaped, and the bottom width of overflow launder 5 is 250mm, and the gradient of isopipe root plane 6 is about 1:
8；To centroclinal, its upper port plane is 0 ° with the angle of cofferdam upper port horizontal line 3 to the upper port of downflow weir 4, and downflow weir 4 overflows
