Description
Technical field
This utility model relates to coking industry technical field, particularly relates to a kind of 7.3m top dress and makes dual-purpose type coke oven firm by ramming.
Technical background
2016 " coking industry " 13 " planning outline " proposes routine coke oven in terms of industry restructuring and, except production metallurgy afocal, also can produce gasification Jiao.The Department of Science and Technology in 2016 mentions in " Coal Clean efficiently utilizes and novel energy-conserving technology " emphasis special project in second batch state key research and development planning item and develops the burnt new technique of low rank coal high temperature pyrolysis preparation gasification at high proportion.Under new industrial policy instructs, innovation structure adjusts, and constantly realizes technological progress.Dual-purpose type coke oven made firm by ramming by a kind of 7.3m of exploitation top dress, same furnace binding, various processes, produce the coke of different quality, make coal chemical enterprise production flexible and changeable, simultaneously for studying low rank coal high temperature pyrolysis preparation gasification burnt new technique offer technical support at high proportion further.While coking furnace shaft maximizes, meet coke oven chimney sulfur dioxide, nitrogen oxides emissions concentration meets GB16171-2012 " coking chemistry emission of industrial pollutants standard ".
Utility model content
This utility model provides a kind of 7.3m top dress and makes dual-purpose type coke oven firm by ramming.
This utility model be the technical scheme is that to include: furnace roof, carbonization chamber, combustor, chute, regenerator, described furnace roof is positioned at above carbonization chamber and combustor, carbonization chamber and combustor distribute alternately, and regenerator is positioned at combustor and carbonization chamber bottom, is connected with combustor by chute.
Further, carbonization chamber height 7.3m, mean breadth are 600mm, belong to coking chamber coke oven with width.
Further, coke oven heating level height is any value between 1000 ~ 1600mm.
Further, combustor is divided into: combustor one section, combustor two-stage nitration, combustor three sections.
Further, regenerator uses lattice and bamboo comb brick bottom adjustable structure；Regenerator sealing wall uses composite silicate heat insulation material；Regenerator sealing designs 30mm thickness ceramic beaverboard insulation material within the walls.
Further, chute burner position uses composite silicate heat insulation material.
The beneficial effects of the utility model are: make gas fully burn in combustor, it is ensured that high to heating uniformity, the generation of minimizing nitrogen oxides, gas flow is adjustable simultaneously, easy to operate, and energy-saving effect is notable, improves production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is texture edge figure of the present utility model.
In figure: 1. furnace roof, 2. carbonization chamber, 3. combustor, 3-1. combustor one section, 3-2 combustor two-stage nitration, 3-3. combustor three sections, 4. chute, 5. regenerator.
Detailed description of the invention
In order to be able to be more clearly understood that the technical solution of the utility model, below in conjunction with the accompanying drawings this utility model is further illustrated.
A kind of 7.3m top dress as shown in Figure 1 makes dual-purpose type coke oven firm by ramming, including furnace roof 1, carbonization chamber 2, combustor 3, chute 4, regenerator 5；Furnace roof is positioned at above carbonization chamber and combustor, and carbonization chamber and combustor distribute alternately, and regenerator is positioned at combustor and carbonization chamber bottom, is connected with combustor by chute.
Described, carbonization chamber 2 mean breadth is 600mm, belongs to coking chamber coke oven with width, and coking chamber coke oven with width carbonization indoor temperature ladder is little, and coal charge coking speed slows down, and the lumpiness of coke increases, and crackle reduces, advantageous particularly to the M40 improving coke；Using wide oven chamber coking time to extend, make the shrinkage value of charge of coke increase, charge of coke increases with the gap of coking chamber wall, it is easy to coke pushing；Square being directly proportional of the bulbs of pressure of coal charge and coking speed, coking speed slows down, and the bulbs of pressure reduce.Wide oven chamber reduces the coke pushing damage to furnace wall, improves coke oven service life.
Described, coke oven heating level height is 1000～1600mm, no matter pushes up dress or tamper production operation all can meet carbonization chamber charge of coke simultaneously maturation up and down, and can reduce the graphite growing amount in furnace roof space.
Described, combustor 3 is divided into: one section of 3-1 of combustor, combustor two-stage nitration 3-2, three sections of 3-3 of combustor, and zone heating structure can reduce the intensity of gas-fired, reduces the generation of NOx.Meanwhile, strengthen waste gas circulation amount and coke-stove gas high burner measure is set, it is ensured that the high uniformity to heating of carbonization chamber, reducing combustion intensity, it is also possible to reduce the generation of NOx further, reduce the pollution to air.
Described, regenerator 5 uses lattice and bamboo comb brick bottom adjustable structure, and it is simpler, accurate to regulate, and makes air-flow distribute rationally in regenerator 5.Additionally using down-regulation type structure, the bamboo comb brick top waste gas temperature difference is little, and the thermal efficiency of coke oven regenerator 5 is high, and energy-saving effect is notable.
Described, in order to improve limit fire path temperature, increase the tightness of regenerator 5 envelope wall, reduce heat loss, reduce basement and the temperature in flue corridor, at regenerator 5 envelope wall and chute burner position, use good heat-insulation effect and the novel heat insulation heat-barrier material not the most being easily cracked；Regenerator 5 envelope designs 30mm thickness ceramic beaverboard insulation material within the walls.
The above is only better embodiment of the present utility model, therefore all equivalence changes done according to structure, feature and the principle described in this utility model patent claim or modification, all it is included in this utility model patent claim.
