In figure: 1-exterior wall 2-knee wall 3-interior wall 4-metal shell 5-gas passage 6-gas communication hole.
Embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but it should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1, Fig. 2, a kind of annular air channel with high stability bearing structure, the high stability bearing structure be made up of interior wall 3, knee wall 2, exterior wall 1, metal shell 4 and gas communication hole 6 is to realize the life-time service of annular air channel; In metal shell, 4 are provided with exterior wall 1, knee wall 2, interior wall 3.Interior wall 3 is connected by some knee walls 2 with exterior wall 1, and exterior wall 1 external stability has metal shell 4, and interior wall 3 is interior arch structure, is connected to form by the multiple interior arch be evenly arranged.Knee wall 2 is supported on the interior arch junction of interior wall 3, and knee wall 2 is for arranging the skeleton construction of gas communication hole 6.The interior arch of interior wall 3 is arcuate structure, and each arc radius is identical, and is distributed on exterior wall 1 circumferentially concentric.Interior arch quantity is more than 3 or 3.Gas communication hole 6 is through holes of geometrical shape.Gas communication hole 6 can be the through hole of arch, circle, ellipse or rectangle.
The overall pressure-bearing with the annular air channel of high stability bearing structure belongs to external pressure pressure-bearing mode.
The metal shell 4 of equipment is for having the cylinder of certain loading strength.Metal shell 4 mainly realizes carrying exterior wall 1 reactive force and supports the effect of exterior wall 1 refractory brick, and metal shell 4 envrionment temperature is less than 200 DEG C, and plain carbon stool material can meet the demands.
Be close to metal shell 4 outside exterior wall 1 to arrange, with knee wall 2 compact siro spinning technology be evenly arranged inside exterior wall 1, be full of the rare gas element of high temperature between exterior wall 1 and interior wall 3, exterior wall 1 is formed by laying fireproof bricks.Multiple knee wall 2 be evenly arranged is connected with inner-outer wall 1, and knee wall 2 is formed by laying fireproof bricks, knee wall 2 is established gas communication hole 6, for the rare gas element hoop circulation after high temperature heat exchange, realizes the collection to rare gas element at gas passage 5.Knee wall 2 mainly realizes the effect of support and firm interior wall 3.The quantity of gas communication hole 6 is determined according to actual needs.
Interior wall 3 is connected to form by multiple interior arch, interior arch quantity is determined according to instrument size, and in each, arch is connected with adjacent 2 knee walls 2, and interior wall 3 is the parts mainly bearing high temperature coke pressure, the arch place of interior wall 3 contacts pressurized with high temperature coke, is external pressure stress form.Interior wall 3 is formed by laying fireproof bricks, and under external pressure, arch has very strong stability, even if the refractory brick that there is destruction and loosen, also can press tighter and tighter, produce very small deformation, stops the destruction of interior wall 3.Interior wall 3 is connected with knee wall 2, knee wall 2 is connected with exterior wall 1, exterior wall 1 is connected with metal shell 4, and dispersion makes the reactive force that refractory brick loosens completely.
Wherein, interior wall 3 is interior arch structure, and connect to form by encircleing in 4 that are evenly arranged, 5,6,8,10 or more quantity, shown in Fig. 1 is the interior wall 3 encircleing connection in 8.Under the prerequisite not affecting the circulation of rare gas element hoop, part knee wall 2 can not arrange gas communication hole 6.The quantity of gas communication hole 6 can be determined according to actual needs such as the flow of rare gas element, flow velocitys.
The utility model Stability Analysis of Structures, inside, without metal parts, is out of shape little, and compact construction is simple, long service life.Interior wall has independent bearing enhancement type external pressure ability, has external pressure larger, the feature that interior wall distortion is less, is the annular air channel of high stability bearing structure.The compression failure of coke to annular air channel wall can be effectively reduced, the radial displacement of strict restriction interior wall, extend the dry stove work-ing life of putting out.
