Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As the sealing structure of Fig. 1~4, a kind of sealing structure preventing water-cooling wall dilatancy, the present embodiment is used for opposite side
Wall water-cooling wall and front-back wall water-cooling wall junction are connected and sealed, i.e., to first water-cooling wall of the present embodiment and the second water-cooling wall
Junction is connected and sealed.
As shown in figs. 1 and 3, the first water-cooling wall includes the vertical water screen tube 1 of more longitudinally spaced arrangements, adjacent vertical
Water screen tube 1 is connected with each other by the first fin 3, and the second water-cooling wall includes longitudinal water screen tube of more laterally spaced arrangements
2, adjacent longitudinal direction water screen tube 2 is connected with each other by the second fin 12.For the sealing of the first water-cooling wall, the present embodiment is adjacent
Airtight and watertight padding between vertical water screen tube 1, airtight and watertight padding include that its vertically arranged longitudinal both ends difference sealing welding exists
It riser 10 on adjacent vertical water screen tube 1 and is fixed on 10 upper end edge horizontal cross of riser and extends to adjacent two vertical water
Transverse slat 11 between cold wall pipe 1.Transverse slat 11 is pushed against on the first fin 3 far from the lateral ends of riser 10.
For the sealing of the second water-cooling wall and the first water-cooling wall junction, the present embodiment is provided with sealing in airtight and watertight padding
Cavity.As shown in Fig. 2, seal cavity is coated on the outermost longitudinal direction water screen tube B of neighbouring vertical water screen tube 1 for preventing
Furnace gas dissipation, seal cavity include the first sealing plate 4 and second of the two sides outermost longitudinal direction water screen tube B or more of being placed in
Sealing plate 5 and third sealing plate 6 positioned at outermost longitudinal direction water screen tube B transverse direction side, the first sealing plate 4 and the second sealing
5 one end of plate is weldingly fixed in airtight and watertight padding, and the other end extends along horizontal transverse direction and forms closed chamber with third sealing plate 6
Body structure, wherein the first sealing plate 4 is overlapped on the upper end of outermost longitudinal direction water screen tube B far from one end of the first water-cooling wall.Cause
It is much larger than the intracorporal pressure of seal chamber for the steam pressure in burner hearth, therefore under the action of steam pressure, the first sealing plate 4
Always it is oppressed in the upper end of outermost longitudinal direction water screen tube B, forms Hermetical connecting structure.
