In concrete enforcement, adjacent hollow refractory brick 2 spacing in left and right are 100～200mm.
The shape of cross section of described hollow refractory brick 2 is regular polygon, is preferably square;
The through hole shape of cross section of described hollow refractory brick 2 central authorities is polygon or circle, is preferably circle.
In concrete enforcement, the side size range of described hollow refractory brick 2 is that 300～400mm, thickness range are 20～50mm;
The centre bore opening diameter scope of described hollow refractory brick 2 is that 200～300mm, circulation area ratio ranges are 40%～60%.
Described access opening 1 is door type refractory brick, and described access opening 1 bottom is fixedly connected with described combustion furnace burner hearth inwall; Described access opening 1 top is fixedly connected with by between wet block mode and hollow refractory brick 2 described in a group.
The shape of cross section of described access opening 1 is dome-shaped;
The altitude range of described access opening 1 is 600～800mm.
Because materials'use condition is directly to contact with high-temperature reacting gas, 1800 ℃ of refractory material classification temperature.Described water conservancy diversion brick wall 1 and access opening 2 all adopt ultralow iron Fe2O3<0.5%, and the refractory brick that the corundum-mullite material of Al2O3 >=88% is made has strengthened high temperature resistant, resistance to peracid and the thermal shock resistance of refractory brick.
Inner lining structure of the present utility model can be in guaranteeing recovery technology of sulfur under the prerequisite of sulfur recovery rate; by guiding and the protective effect of tracery wall; make speed, temperature and the CONCENTRATION DISTRIBUTION of furnace gas more even; reach the uniform distribution that improves exhaust-heat boiler inlet place, downstream gas flowfield; prevent the impact of inhomogeneous high-temperature gas to furnace lining and tube sheet, make the object that condensation of gas process is more efficient and stable.
Feature of the present utility model is:
1) adopt hollow refractory brick circular in outer square to form hole structure tracery wall; form cellular air-flow guiding and distribute; strengthen temperature, speed and the CONCENTRATION DISTRIBUTION uniformity of gas stream in the stove; increase the time of staying of reaction gas flow; and protect the tube sheet of upstream device waste heat boiler, avoid the thermal shock of high temperature gas flow when unstable.
2) in the larger-diameter combustion furnace burner hearth of large-scale sulfur recovery facility, adopt hole structure tracery wall, square rim Area of bearing is large, and structure is more firm.According to size of burner hearth, circulation area ratio, the acceptable monolithic quality of a dead lift while taking into account the rational molding thickness of treasure maesa herb wall brick and construction, the length of side and the opening diameter of adjustment tracery wall brick.
3) hole structure tracery wall adopts combination to build pattern by laying bricks or stones, takes into account the function of zones of different: wet block is used for keeping supporting & stablizing, and convenient adjustment of laid dry stacked quantity.
4) at the larger tracery wall center of diameter or center, dome-shaped access opening is set position on the lower, in passage, can piles up tracery wall brick.Equipment is stopped work while carrying out internal overhaul, this part fragment of brick can be moved to formation passage, improves the passability of tracery wall.
Compared with prior art, the utility model is by having taken into full account temperature and the ambient condition in such combustion furnace high-temp combustion region, a set of combined flower wall brick of optimization design.This scheme design form is simple, rational in infrastructure, and agent structure is stable, and material is sturdy and durable.The utility model is for energy-conserving and environment-protective, assurance safety operation and effectively reduce material cost important in inhibiting.
