The two ends of described furred ceiling pipe are accessed respectively in the sleeve pipe of top cover case of corresponding position.
The utility model compared with the existing technology, adopts snakelike tube bank to be suspended on the furred ceiling pipe, and snakelike tube bank can freely swing, and is difficult for dust stratification, connects rapping Guan Hougeng easy-to-clean ash; Snakelike tube bank passes body of heater by top cover housing-case pipe, and without the furnace wall poling, good seal performance, solved the troilite boiler because of SO
2smoke spillage and cause the problem of corrosion; Whole group of heated surface bundle is manufactured in factory, has guaranteed the product workmanship, shortens on-the-spot installation period, for the overall performance of the waste heat boiler of the iron acid system of sulphur provides Reliable guarantee.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The left view that Fig. 2 is Fig. 1.
The top view that Fig. 3 is Fig. 1, not shown steelframe.
The specific embodiment
Now the utility model is further described by reference to the accompanying drawings.
Embodiment 1
Referring to Fig. 1～Fig. 3, the utility model comprises snakelike tube bank, furred ceiling pipe, rapping pipe, top cover case, header, it is characterized in that: the interior sleeve pipe 4-4 that vertically is laid with of top cover case 4, be socketed respectively the suspension rod 2-2 top of front and back to the U-shaped arranged in the sleeve pipe 4-4 of top cover case 4 left and right sides, prop up the upper furred ceiling pipe 2 of left and right to horizontally disposed U-shaped that connect of suspension rod 2-2, the bent portion of every snakelike tube bank 1 is mounted on a furred ceiling pipe 2, referring to Fig. 1.The left and right end of every snakelike tube bank 1 upwards runs through respectively after the sleeve pipe 4-4 in the top cover case 4 of corresponding position header 5 welding with the left and right sides.Here snakelike tube bank 1 passes body of heater by the sleeve pipe 4-4 of top cover case, and without the furnace wall poling, good seal performance, solved the troilite boiler because of SO
2smoke spillage and cause the problem of corrosion.
Described top cover case 4 tops are provided with top cover 4-1, and the bottom of top cover case is provided with base plate 4-2, fill out in top cover case 4 and are provided with heat insulation layer 4-3.Top cover case 4 is fixed on steelframe 6, and steelframe 6 plays the effect of supporting whole group of snakelike tube bank here.And the sleeve pipe 4-4 of top cover case 4 interior layings, for pipe and a suspension rod 2-2 of the pipe of wearing snakelike tube bank 1 and furred ceiling pipe 2, in order to seal welding.
