Abstract
The invention provides an anti-wear structure for water-cooled wall pipes at four corners of a circulating fluidized bed boiler, which can prevent the wear of the water-cooled wall pipes at the four corners of a water-cooled wall and ensure the safe operation of the water-cooled wall. The technical scheme of the anti-wear structure is as follows: the anti-wear structure comprises the water-cooled wall pipes at the four corners of the water-cooled wall and is characterized in that a refractory material wall is arranged between the corner of the two adjacent water-cooled walls nearest to the four wall-cooled wall pipes from top to bottom.
Description
Technical field
The present invention relates to the mechanical mechanism field of CFBB bed, be specially the abrasion-proof structure of the water screen tube that is used for four jiaos of places of CFBB.
Background technology
Circulation and outer circulation in the material circulation of CFBB is divided into, outer circulation is to finish by external gas-solid separator and returning charge valve, in circulation be material in the burner hearth in uphill process since self gravitation effect and wall effect form, wherein the wall effect since excessive effects at the material concentrations at four jiaos on water-cooling wall place apparently higher than other position of water-cooling wall, high concentration region 1, low concentration region 2 are seen Fig. 1, it can cause four jiaos of water screen tube serious wear of locating of water-cooling wall, has influence on the safety of water-cooling wall.
Summary of the invention
At the problems referred to above, the invention provides the abrasion-proof structure of the water screen tube that is used for four jiaos of places of CFBB, it prevents the wearing and tearing of the water screen tube at four jiaos of places of water-cooling wall, guarantees the safe operation of water-cooling wall.
The abrasion-proof structure that is used for the water screen tube at four jiaos of places of CFBB, its technical scheme is such: the water screen tubes that it comprises four jiaos on water-cooling wall place is characterized in that: the corner of the adjacent water-cooling wall of two-phase near between four water screen tubes the refractory material wall being housed from top to bottom.
It is further characterized in that: the arc surface in opposite directions of second water screen tube of the adjacent water-cooling wall of described two-phase is welded with wear-resisting arc plate, the fit arc surface of described second water screen tube of the inner arc surface of described wear-resisting arc plate, the exterior arc surface of described wear-resisting arc plate is welded with the V-type bitch, and described V-type bitch is distributed in the short transverse of the exterior arc surface of described wear-resisting arc plate;
Described not in opposite directions at the horizontal opening of the V-type bitch of same water screen tube, the horizontal opening of described V-type bitch at same water screen tube is towards identical;
Described wear-resisting arc plate overlaps the arc surface in opposite directions that covers described second water screen tube up and down, after lap-joint's electric welding of the described wear-resisting arc plate of overlap joint up and down, leave the surplus of short transverse separately;
The refractory material that described refractory material wall is specially between the wear-resisting arc plate that is cast in the adjacent water-cooling wall of described two-phase, first water screen tube forms;
Described refractory material is specially abrasion-resistant corundum.
After adopting structure of the present invention, since the corner of the adjacent water-cooling wall of two-phase near the refractory material wall is housed between four water screen tubes from top to bottom, during its wearing and tearing, only can produce wearing and tearing to the high-abrasive material wall, can not have influence on the water screen tube at four jiaos of places of water-cooling wall, it prevents the wearing and tearing of the pipe at four jiaos of places of water-cooling wall, guarantees the safe operation of water-cooling wall.
