Embodiment
Below in conjunction with Figure of description, the present invention is described in detail, but it should be noted that enforcement of the present invention is not limited to following embodiment.
As shown in figs 2-4, a kind of producer gas generator retort section fire proof material of furnace lining masonry construction, the cross section of the air guide channel in masonry construction is fan-shaped.
Cross section is fan-shaped air guide through hole is built by laying bricks or stones on cylinder inboard wall formed by soft clay insulating brick 3, outer arcuate refractory brick 4, arc refractory brick 5, wedge shape refractory brick 6, described soft clay insulating brick 3 is fixed on cylinder inboard wall, outer arcuate refractory brick 4 is fixedly connected with soft clay insulating brick 3 inwall, outer arcuate refractory brick 4 is connected with arc refractory brick 5 by wedge shape refractory brick 6, the inwall of outer arcuate refractory brick 4, forms fan-shaped air guide through hole 7 between the outer wall of arc refractory brick 5 and wedge shape refractory brick 6.
Cylindrical shell comprises Plate Welding cylinder 1, pure aluminium silicate insulation quilt 2, and pure aluminium silicate insulation quilt 2 is fixed on Plate Welding cylinder 1 inwall.
Embodiment: take furnace diameter as the two stage type gas generating furnace of 3600mm be example, prior art build in body structure the air guide channel 8 (see Fig. 1) being provided with 36 φ 168mm circular holes by laying bricks or stones, its cross-sectional area is: 0.79 ㎡, to build air guide channel 7 in body structure by laying bricks or stones be 12 fan air guide channels of the present invention, its cross-sectional area is: 2.1 ㎡, and the cross-sectional area of air guide channel adds 1.31 ㎡.Because of the improvement of cross-sectional area, significantly improve the circulation status of combustion gas in air guide channel 7, reduce plugging fault rate, extend the equipment use time, energy-saving effect can save energy 10% compared with original technology.
The relation of building by laying bricks or stones mutually of refractory material laying structure is: outside is Plate Welding cylinder 1, and inside is the inwall formation pure aluminium silicate insulation carpet veneer of pure aluminium silicate insulation quilt 2 around Plate Welding cylinder 1; To be built by laying bricks or stones around pure aluminium silicate insulation quilt 2 layers of inwall by the outer shroud soft clay insulating brick 3 of building by laying bricks or stones and form soft clay insulating brick 3 layers; 4 layers, outer arcuate refractory brick is formed around the inwall of soft clay insulating brick 3 layers by the outer arcuate refractory brick 4 of building by laying bricks or stones; 5 layers, arc refractory brick is formed by the arc refractory brick 5 of building inner ring by laying bricks or stones; Hollow layer is left outside between arc-shaped refractory brick 4 layers and 5 layers, arc refractory brick, Ge Ceng center and body centre are concentric(al) circles, wedge shape refractory brick 6 is built by laying bricks or stones outside between arc-shaped refractory brick 4 layers and 5 layers, arc refractory brick, and the hollow layer between 4 layers, outer arcuate refractory brick and 5 layers, arc refractory brick is divided into independently 12 fan hole air guide channels 7, and successively upwards superpose, staggered building by laying bricks or stones form cone inner core.In whole masonry construction, the external arc-shaped refractory brick 4 layers of wedge shape refractory brick 6 plays with 5 layers, arc refractory brick the effect being connected and reinforcing.
Plate Welding cylinder 1 in embodiment is that δ 8mm steel plate is welded after rotary machine rolls by thickness of slab, mainly seals and strengthen fixed cylinder effect, avoiding the combustion gas of building body inside by laying bricks or stones to leak.
Pure aluminium silicate insulation quilt 2 layers is by the thickening layer of cylinder body outer wall in inner barrel, and object is soft clay insulating brick 3 layers insulation, decreases the loss of heat.
Soft clay insulating brick 3 layers avoids fuel gas temperature in cylindrical shell to be radiated on welding steel cylinder 1, and object reduces heat energy loss.
