Description
Technical field
It is double more specifically to a kind of coke dry quenching furnace refractory lining the invention belongs to metallurgical equipment the realm of building construction
Chute.
Background technology
Quenching is important step in coke production, there is two kinds of coke wet quenching and CDQ, and dry method is mostly used at present
Quenching come reach environmental protection and energy-conservation requirement.A set of dry quenching system engineering is by quenching stove, one-time dedusting, preboiler, secondary
Dedusting and circulating fan etc. are constituted, and quenching stove is made up of top cone, the room that prestores (ring air channel), slope air course and cooling chamber.
It is to apply inert gas by red heat for the red burnt technique of traditional wet-treating that dry coke quenching technique, which is,
Coke is cooled down in coke dry quenching furnace and discharges coke, and inert gas is changed with demineralized water in the boiler after first dedusting after heat exchange
Heat, produces steam, the process recycled through final dusting under the suction of circulating fan.Dry coke quenching technique has back due to it
The advantages of receiving the energy, environmental protection, improve coke quality, as the work that must be clearly used in Chinese coking industry permit standard
Skill.
Coke dry quenching furnace is made up of top cone, the room that prestores (ring air channel), slope air course and cooling chamber.From structure design,
Slope air course position is crucial, and one side slope air course ox pin supporting brick will bear the weight of resistance to material inside top partition wall and ring air channel,
Body of heater is laid particular stress in production process, and slope air course supporting brick bears weight offset, discontinuity；On the other hand it is that slope air course position is resistance to
Fiery material work bad environments, are washed away, coke is rubbed, chemical etching is acted on by temperature fusion, rapid heat cycle, air blast for a long time
Deng the influence of environment, thus cause the fracture of slope air course position supporting brick, resistance to material is damaged fastest, is whole coke dry quenching furnace body
The life-span bottleneck of resistance to material, the life-span is only more than about 1 year, and the service life of refractory material at other positions of coke dry quenching furnace body about 8 years.
The service life of coke dry quenching furnace depends on the life-span of chute area refractory lining, it is general go into operation 1 year to a year and a half will
Annual overhaul, main is exactly that the chute corbels support wall of damage is repaired, in the past using monocline road structure, monocline road corbels support
Limited when the basis of wall and top expansion displacement by left and right wall inner lining, be not susceptible to move, but monocline road corbels support
Left and right is hanging without support in the middle part of wall, easily displacement is produced when expanding, so as to cause the bracket brick of monocline road corbels support wall
Bulging or fracture, the security of reduction coke dry quenching furnace production, limit the service life of coke dry quenching furnace.
Diclinic road then adds askew arch pillar wall in the middle of former monocline road bracket, artificially by a complete chute cut-off point
For two chutes, bracket middle part is set to be supported the left and right support of arch, displacement is limited when being allowed to expand, so as to increase bracket
Steadiness.Built by laying bricks or stones because diclinic road bracket has hyperboloid double arch, difficulty of construction is larger, is precisely controlled difficulty bigger.
Simultaneously because coke dry quenching furnace box hat size, bulk heterotypic fire brick appearance and size have certain error, if accumulated error exceeds one
Determine scope, then chute modular tile can be caused can not to close door.
Chinese patent, publication number：CN101928575A, publication date：In the patent of invention on December 29th, 2010, disclose
A kind of dry quenching laying method, builds coke quenching tank by laying bricks or stones, builds disposable dust remover, quenching pan furnace by laying bricks or stones in advance and construct and once remove including pre-
Dirt masonry heater is constructed.The program is in coke oven construction is put out, when being constructed to the 82-114th layer of slope air course, during unwrapping wire, and upper and lower part is adjusted
Knothole center and slope air course dividing wall center superposition, by coke quenching tank with being separated on the basis of disposable dust remover longitudinal centre line during unwrapping wire
Reticule, this line is connected to ring air flue and crosses top, and adjustment hole center and size are as control foundation up and down, when interior ringwall is built by laying bricks or stones
An absolute altitude control point is provided every 500-700mm on brick working face, is put with this and controls every layer with brick layer control-rod for foundation
Brick builds absolute altitude by laying bricks or stones.According to disposable dust remover longitudinal centre line at opening portion, the position of both walls is provided on the 92nd layer of brick surface
Line；The position of line bar control opening portion wall and absolute altitude, when slope air course is built by laying bricks or stones, the 76th layer of dividing wall is crossed below dome brick and installs support,
During 76-81 layers of brick masonry, this four layers of brick horizon rules and the strict control surface flatness of 2m guiding rulers and absolute altitude, radius center
Wheel column control, 81-111 layers of exterior wall are processed into treasured to be built by laying bricks or stones at 180 ° of dividing walls to both sides with opening portion stalk junction brick
Sword hair style is built by laying bricks or stones.The program can control the index center and absolute altitude of a dividing wall, but resistance to the Idiotype for building by laying bricks or stones
The size of firebrick and the error produced when building by laying bricks or stones are uncontrollable, it is impossible to ensure that junction modular tile can smoothly close door, with reference to
Not enough, the stability and precision of structure all cannot be guaranteed the occlusion degree at place.
