Description
Technical field
The utility model relates to coking by coke oven technical field more particularly to a kind of coke oven smoke centralized collection systems.
Background technique
In recent years, as new " coke oven atmosphere pollutants emission standards " start to execute, environmental requirement is increasingly stringenter,
The emission request of the pollutants such as flue dust and exhaust gas is also increased substantially therewith.The pollutant emission of coke oven both includes coal
Dirt, Jiao Chen, and contain toxic gas, it is always the field of environmental protection administration's emphasis supervision.It comes out of the stove although for many years having developed
Push up organized flue dust and pernicious gas that dust collection for charging system, pusher side pushing dust removing system, coke side coke discharging and dedusting system form
Exhaust system, but this 3 dust pelletizing systems respectively separate configurations, work independently, therefore occupied space is big, and project inputs are big, equipment
Maintenance is big, and the cost performance of coke oven is caused to reduce.In addition, facing for coaling hole imprecision, tedge of coke oven door blowby, furnace roof
When discharge, the inorganization pollutant of accidental generation can not be still collected in the switch multiple tracks production process such as fire door.
In view of problem above, most practical and effective solution method is exactly by a large-scale closed cover coke oven
In entirety is covered on, the high-temperature gas and flue dust of uncontrollable discharge are converged to covering on top, to realize centralized collection and place
Reason.The flue dust and pernicious gas that it was discharged in a organized way coaling, pusher side coke pushing, coke side discharge of the coke can also be by same set of dedusting systems
System carries out centralized collection and processing.
Therefore, how to design a kind of covering coking furnace shaft comprehensively, to coke oven discharge in a organized way coaling, pusher side coke pushing, coke
The discharge of the coke loss flue dust of flue dust and pernicious gas and uncontrollable discharge of side carries out centralized collection, and not to production vehicle and furnace body
The totally-enclosed coke oven smoke collection system that equipment has an impact, is main problem to be solved in the utility model.
Traditional coke oven smoke collection device is primarily present following point:
1, traditional coke oven is not provided with coke oven smoke centralized collection system, and coke oven is in open environment, and existing removes
Dirt system can only to discharge in a organized way discharge of the coke flue dust and dust collection for charging is collected, can not be to the loss of coke oven uncontrollable discharge
Flue dust is collected, and causes atmosphere pollution, is unable to satisfy new environmental requirement；
Even if 2, some coke ovens are provided with the smoke collecting device (Chinese patent that such as application publication number is CN107828430A
Disclosed " a kind of dust excluding hood of coke oven "), a semienclosed cover only also is set in furnace roof part, therefore can only be to coke oven furnace
The flue dust of top loss is collected, and the pusher side of coke oven, coke side loss flue dust can not be carried out comprehensive collection, is also unable to satisfy new
Environmental requirement.
3, traditional coke oven is equipped with furnace roof dust collection for charging system, pusher side pushing dust removing system, coke side coke discharging and dedusting system etc.
The collection processing system implementing of organized discharge flue dust and pernicious gas, but 3 dust pelletizing systems are respectively independently arranged and work, and occupy empty
Between it is big, project inputs are big, and plant maintenance amount is big, and the cost performance of coke oven reduces.
Summary of the invention
The utility model provides a kind of coke oven smoke centralized collection system, realizes to the complete of totally-enclosed rear coke oven smoke
Face collect, including coalingging, coke pushing and discharge of the coke operation when paroxysmal flue dust and each position loss flue dust, overall structure letter

2-5, coke side the flue dust collecting pipe 2-1 that discharges of the coke are pooled in flue dust collecting general pipeline 2-8, are re-fed into dedusting earth station and are carried out innoxious place
Reason；Realize the flue dust that coke oven is discharged in a organized way after totally-enclosed and pernicious gas and uncontrollable discharge loss flue dust and
Toxic gas carries out centralized collection and processing；
2) when the production of coke oven 3 is in abnormal condition, when coke oven smoke centralized collection system 2 can not work normally, to protect
There are enough air in card totally enclosed type cover 1, avoids flammable explosive gas concentration from increasing, it is ensured that operating personnel and production facility
Safety, opened skylight 11 is simultaneously by accident condition air supply tube 7 to 1 inner blower of totally enclosed type cover；When coke oven 3 restores normal
After production status, turns off skylight 11 and stop to 1 inner blower of totally enclosed type cover.
The coke oven smoke centralized collection system 2 realizes the automatic adjustment that exhaust gas volumn is collected with coke oven control system linkage,
When the n-th hole carbonization chamber carries out pushing coke operation, the pusher side coke-pusher smoke regulating valve 2-6 of the n-th hole carbonization chamber, the n-th hole carbonization chamber
Coke side discharge of the coke flue dust regulating valve 2-2, the n-th -2 hole carbonization chamber furnace roof coal-charging smoke regulating valve 2-4 aperture be adjusted to 80%~
100%, the corresponding pusher side coke-pusher smoke regulating valve 2-6 of remaining each hole carbonization chamber, coke side discharge of the coke flue dust regulating valve 2-2, furnace roof dress
The aperture of coal smoke dirt regulating valve 2-4 is adjusted to 0~20% respectively.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
