Abstract
The invention relates to a coke dry quenching device, which comprises a dry quenching furnace. An annular channel outlet of the dry quenching furnace is connected with an inlet of a primary deduster; an outlet of the primary deduster is connected with an inlet of a waste heat boiler; an outlet of the waste heat boiler is connected with an inlet of a secondary deduster; an outlet of the secondary deduster is connected with an inlet of an auxiliary coal economizer through a main circulating fan; an outlet of the auxiliary coal economizer is connected with an air inlet on the lower part of the dry quenching furnace; two sides of a channel of the primary deduster are provided with a plurality of pairs of regenerative burners which are arranged symmetrically; and the outer ends of the regenerative burners are connected with a combustion control system. The coke dry quenching device is reasonable in design, low in manufacturing cost, and safe and reliable in operation, can completely combust combustible components in circulating gas, greatly reduces the oxygen content in the circulating gas, reduces red-hot coke burning loss, ensures that surplus flue gas in the circulating system is discharged through the regenerative nozzles at the primary deduster at a low temperature, and reduces energy consumption.
Description
Technical field:
The present invention relates to a kind of dry coke quenching auxiliary.
Background technology:
Dry coke quenching auxiliary is that the gordian technique of China current energy-saving and emission-reduction aspect is special, so-called dry coke quenching, and relative wet quenching is meant and adopts rare gas element with a kind of coke quenching method of red burnt cooling refrigerative.Its technical superiority aspect UTILIZATION OF VESIDUAL HEAT IN, raising coke quality and environment protection has obtained everybody generally approval.But dry coke quenching auxiliary also has many detailed problems to be worth everybody to improve and optimizes, and mainly shows:
The one, also have about 10% in force down warm rare gas element and bleed off in vain, waste energy;
The 2nd, in recycle gas, both contained inflammable gas (CO, H2 etc.), contain free oxygen again, combustion processes is insufficient, and it is big to cause red incipient scorch to decrease;
The 3rd, the major cycle piping system is provided with complicacy, and equipment is many, and cost is high.
Summary of the invention:
The invention provides a kind of dry coke quenching auxiliary, it is reasonable in design, and cost is low; Safe and reliable to operation, can make the combustiblecomponents perfect combustion in the recycle gas, reduce the oxygen content in the recycle gas greatly; Reducing red incipient scorch decreases; Unnecessary flue gas in the recycle system is discharged from the heat-accumulating burner low temperature of disposable dust remover, has reduced energy consumption, has solved the problem that exists in the prior art.
The present invention solves the problems of the technologies described above the technical scheme that is adopted to be: it comprises the dried stove that puts out; Dried circular channel outlet of putting out stove links to each other with the inlet of disposable dust remover; The outlet of disposable dust remover links to each other with exhaust-heat boiler inlet; The outlet of waste heat boiler links to each other with the inlet of secondary filter, and the outlet of secondary filter links to each other with the inlet of secondary economizer through the major cycle blower fan, and the outlet of secondary economizer links to each other with the dried blast inlet that puts out the stove bottom; Be provided with somely to symmetrically arranged heat-accumulating burner in the passage both sides of disposable dust remover, the outer end of heat-accumulating burner links to each other with combustion control system respectively.
Said some feeder connection sides that symmetrically arranged heat-accumulating burner is arranged on disposable dust remover.
The present invention compared with prior art, the beneficial effect that has is:
1, air-supplied from disposable dust remover inlet sidepiece through the heat-accumulating burner pressure, because air is to force the high temperature ejection, can make the rapid fully burning of inflammable gas in the inertia recycle gas, can contain O to gaseous constituent
2Amount is reduced to minimum, makes the dried high temperature coke that puts out in the stove reduce scaling loss.
2, owing to adopt heat storage type combustion in the ingress of disposable dust remover; Its average funnel temperature can be controlled in below 120 ℃; Thereby realize that the unnecessary flue gas of major circulatory system low temperature before the major cycle blower fan discharges; Than behind the major cycle blower fan, discharging (130～150 ℃) more energy-conservation economize on electricity, further reduced the power consumption of major cycle blower fan, help energy-conservation.
3, owing to use heat-accumulating burner in the disposable dust remover ingress; Can be with removals such as the cold wind suction apparatus in the former dry coke quenching auxiliary, cold flue gas air mix facilities, unnecessary flue gas dischargers; Greatly reduce the cost of dry coke quenching engineering, and improved the property safe and reliable to operation of equipment greatly.
Description of drawings:
Fig. 1 is the catenation principle synoptic diagram of dry coke quenching auxiliary of the present invention.
Fig. 2 is the positional structure synoptic diagram of heat-accumulating burner of the present invention.
Fig. 3 analyses and observe the part-structure synoptic diagram for the A-A among Fig. 2.
Among the figure, 1, the dried stove that puts out; 2, disposable dust remover; 3, waste heat boiler; 4, secondary filter; 5, major cycle blower fan; 6, secondary economizer; 7, heat-accumulating burner.
Embodiment:
For clearly demonstrating the technical characterstic of this programme, below through embodiment, and combine its accompanying drawing, the present invention is set forth in detail.
Shown in Fig. 1～3; The present invention includes the dried stove 1 that puts out; Dried circular channel outlet of putting out stove 1 links to each other with the inlet of disposable dust remover 2, and the outlet of disposable dust remover 2 links to each other with waste heat boiler 3 inlets, and the outlet of waste heat boiler 3 links to each other with the inlet of secondary filter 4; The outlet of secondary filter 4 links to each other through the inlet of major cycle blower fan 5 with secondary economizer 6, and the outlet of secondary economizer 6 links to each other with the dried blast inlet that puts out stove 1 bottom; Be provided with somely to symmetrically arranged heat-accumulating burner 7 in the passage both sides of disposable dust remover 2, the outer end of heat-accumulating burner 7 links to each other with combustion control system respectively.
Said some feeder connection sides that symmetrically arranged heat-accumulating burner 7 is arranged on disposable dust remover 2.
Heat-accumulating burner 7 in the dry coke quenching auxiliary of the present invention externally following timing of accomplishing air and flue gas of cooperation of combustion control system switches.When the heat-accumulating burner 7 of a side blows warm air in the inlet side passage of disposable dust remover 2; When combustible gas component in the recycle gas is burnt; 7 effects of playing a smoke outlet of the heat-accumulating burner of opposite side, the heat storage of hot flue gas through 7 li of heat-accumulating burners that utilizes fume extraction fan to extract out in the recycle gas carries out accumulation of heat.After heat holds foot, the reversing valve action in the combustion control system, the function of two heat-accumulating burners 7 of conversion.In heat exchange, ducted average spent air temp is usually below 120 ℃, thereby no matter is that reversing valve or fume extraction fan in the combustion control system all can the long-term safety reliable work.Heat-accumulating burner 7 has been realized the effect of high efficiente callback fume afterheat, thereby has both reclaimed the part net heat, has improved the perfect combustion operating mode of inflammable gas in the dry coke quenching auxiliary again greatly.
Above-mentioned embodiment can not be as the restriction to protection domain of the present invention, and for the technician in present technique field, any alternate modification or conversion that embodiment of the present invention is made all drop in protection scope of the present invention.
