Description
Technical field
The utility model relates to metallurgical furnace kiln, specifically belongs to a kind of coke dry quenching furnace for coking industry.
Background technology
Coke dry quenching furnace technical development is very fast, domesticly from the 75t/h coke dry quenching furnace of introducing, develops into nowadays large-scale coke dry quenching furnace, and furnace lining structure and material all vary widely.Coke dry quenching furnace generally has the section of prestoring, chute, annular passage, cooling section; At present, the more problems that coke dry quenching furnace produces at chute, annular passage.By analysis, its reason is mainly: the one, and the body weight that the bracket of chute supports annular passage interior wall is large, and the pressure of formation is large, and its bracket is again oblique structure, the pressure bearing mainly concentrates on bracket bottom, therefore cause easily producing distortion, peeling off and burst phenomenon; The 2nd, the bracket of chute is brick laying structure, and bearing resistance is relatively little, easily produces and collapses; Moreover the annular passage problem that also easily produces bulging, collapse.When being damaged, can only scrap and again build, general new building up the coke dry quenching furnace needs time of more than 80 days, for there is no the Steel Plant of dry coke quenching surplus capacity, coke dry quenching furnace can only be used coke wet quenching between turn(a)round, moisture increases, the coke ratio of iron-smelting blast furnace also increases, and cost also increases, and produces stable smooth operation more difficult.
Through retrieving: the patent documentation that Chinese Patent Application No. is CN200910219854.8, it discloses a kind of the have annular passage of new texture and the dry stove that puts out of chute.It comprises annular passage interior wall, chute, and its annular passage interior wall is suspended structure, by suspending cooling cylinder, refractory brick, mould material and lagging material, is composited.Suspending cooling cylinder is hung interior wall integral body in the metal construction of furnace shell, the arranged outside refractory brick of annular passage interior wall, and central authorities are cooling cylinders, between refractory brick and cooling cylinder, lagging material are set, annular passage interior wall bottom arranges mould material.In chute, arrange or lattice partition wall is not set and all can.The key of this document is that can suspending cooling cylinder stand the impact of high temperature, and how distortion refractory adapts to.
Chinese Patent Application No. is the patent documentation of CN200910219858.6, it discloses a kind of dry stove that puts out of new texture, comprise cooling room, oblique flue, annular passage and the chamber that prestores, it is that cooling room diameter is identical with the chamber diameter that prestores, tiltedly the inner extension supporting of flue; Horizontal support is set in annular passage, is provided with half high knee wall.Its deficiency is can't resolve the destruction problem of bracket to equipment, and to be subject to breakage be to build by laying bricks or stones by integral replacing, needs by the deficiency that waits long in time limit.
Chinese Patent Application No. is the patent documentation of CN201020665264.6, it discloses a kind of dry stove that puts out, it comprises outer walling, interior walling, masonry between the chute between outer walling and interior walling bottom, in described interior walling, it is the chamber that prestores, between described interior walling and outer walling, be to be looped around the outdoor annular passage that prestores, along interior walling, circumferentially at interior walling bottom interval, be provided with one group of groove, the described chamber that prestores is communicated with annular passage by groove, circumferential along interior walling, between the interior walling above groove and outer walling, be arranged at intervals with one group of crossbeam.The pressure that bear interior walling middle part and middle and upper part is maximum, and the deformation constrain ability of interior walling bottom to middle part, therefore by setting up crossbeam, by crossbeam, power is passed to the steel structure casing in outer walling and outer walling outside, support and the deformation constrain of internal walling have effectively been guaranteed, can avoid occurring " bulge " phenomenon, extend dry work-ing life of putting out stove.From actual investigation and analysis result, because bulge generally occurs in middle and lower part, crossbeam is difficult to stop the bulging of refractory materials.
Chinese Patent Application No. is respectively the patent documentation of CN200910248855.5, CN200920288492.3, disclose respectively a kind of dry stove that puts out of air cooling slant flue technique that adopts and related to a kind of dry stove that puts out that adopts air cooling slant flue technique, it includes cooling room, oblique flue, annular passage, chamber prestores, it is that oblique mid-feather inside is refrigerating unit, and outside is refractory brick.Refrigerating unit adopts metal construction; In refrigerating unit, be provided with snakelike gas passage, snakelike gas passage is connected with outside gas pipeline by arm.Refrigerating unit top is provided with brick plate, and the refractory materials of brick plate upper and lower part is divided into two parts.This structure can extend dry work-ing life of putting out stove chute partition wall, has simplified the dry method for maintaining that puts out stove chute partition wall simultaneously, has shortened maintenance cycle, has reduced the investment of air importing and cooling gas return-flow system.But it exists the problem of the cooling easy increase stress rupture of chute, annular passage to solve and still exists.
