The beneficial effects of the utility model: the shoe of a kind of circulating fluidized bed boiler water-cooling wall sidewall of the present utility model, comprise the fin that is arranged at water screen tube, and the first pin and the second pin that are arranged at fin surface; The first pin is arranged at the top of the second pin; Fin comprise be connected in the vertical edge on water screen tube surface, join with one end of vertical edge and with the vertically disposed horizontal edge of water screen tube and the hypotenuse that tilts to be connected in the other end of vertical edge; Angle between vertical edge and hypotenuse is set to acute angle; The first pin and horizontal edge are for be arrangeding in parallel, and the second pin and hypotenuse are for be arrangeding in parallel.Because fin surface is provided with the first pin and the second pin, make the shoe of this circulating fluidized bed boiler water-cooling wall sidewall have advantages of that abrasionproof is effective and the abrasionproof effect duration is long, can avoid CFBB that sidewall pipe explosion accident easily occurs, extend the parallel-adder settle-out time of CFBB, thereby enhance productivity.
Accompanying drawing explanation
Fig. 1 is the structural representation of the shoe of a kind of circulating fluidized bed boiler water-cooling wall sidewall of the present utility model.
In Fig. 1, include:
1---water screen tube,
2---fin, 21---vertical edge, 22---horizontal edge, 23---hypotenuse,
3---the first pin,
4---the second pin.
The specific embodiment
The utility model is described in further detail with the following Examples.
embodiment 1.
See Fig. 1.The shoe of a kind of circulating fluidized bed boiler water-cooling wall sidewall of the present embodiment, comprises the fin 2 that is arranged at water screen tube 1, and the first pin 3 and the second pin 4 that are arranged at fin 2 surfaces; The first pin 3 is arranged at the top of the second pin 4; Fin 2 comprise be connected in the vertical edge 21 on water screen tube 1 surface, join with one end of vertical edge 21 and with the vertically disposed horizontal edge 22 of water screen tube 1 and the hypotenuse 23 that tilts to be connected in the other end of vertical edge 21; Angle between vertical edge 21 and hypotenuse 23 is set to acute angle; The first pin 3 is with horizontal edge 22 for be arrangeding in parallel, and the second pin 4 and hypotenuse 23 are for be arrangeding in parallel.Because fin 2 surfaces are provided with the first pin 3 and the second pin 4, and the first pin 3 is parallel to horizontal edge 22, the second pin 4 is parallel to hypotenuse 23, make the shoe of this circulating fluidized bed boiler water-cooling wall sidewall have advantages of that abrasionproof is effective and the abrasionproof effect duration is long, extend the parallel-adder settle-out time of CFBB, thereby enhance productivity.In addition, the first pin 3 and the second pin 4 can also reduce the adherent descending flow velocity of material, thereby improve heat exchange efficiency.
