Description
Technical field
The present invention relates to coke oven smoke treatment technical field, more particularly to a kind of flow guiding type pusher side furnace door sealing device.
Background technology
Tamping coke furnace coking is one kind of mechanization chamber type coking process, compared with the dress coke oven of top, can increase weakly caking coal
Match, efficiently utilize coking coal resource, be the selection process technology for being adapted to China's coking coal resource situation, current tamping coking work
Skill has been obtained for extensive use in China.
However, fill coke oven relative to top, the flue dust that tamping coke furnace is produced during coalingging has that exhaust gas volumn is big, water content
The features such as high and big viscosity, side coal technique is more used due to coalingging, carbonization chamber and atmosphere contacting surface are big during coalingging
And causing smoke catching difficulty big so that flue dust is escaped seriously during tamping coke oven coal-charging, and atmospheric environment is caused seriously
Pollution.
The trapping and processing of the flue dust produced for tamping coke oven coal-charging process, numerous environmental workers and relevant technical people
Member has put into substantial amounts of energy, also applies a variety of Processing tecchnics and technology, wet dust removal is net after such as furnace top smoke catching burning
Combine dry-type floor dust removing station purification technique after chemical industry skill, furnace top smoke catching burning, using furnace roof U-tube smoke guide device by cigarette
Conductance enters coal gas collection system and combines burner smoke trapping earth station handling process etc..These coal-charging smoke Processing tecchnics are to making firm by ramming
Coke oven coal-charging smoke serves certain control and catharsis, but for coalingging during escaped at the fire door that pusher side is opened wide
Flue dust, fail to carry out highly effective control and collection, cause that to escape flue dust during tamping coke oven coal-charging still serious,
Pollution to environment is still continuing, and huge environmental protection pressure is brought to manufacturing enterprise, limits make firm by ramming to a certain extent
The application and popularization of coking technology.
The flue dust escaped during for tamping coke oven coal-charging at the fire door that pusher side is opened wide, is typically employed at pusher side fire door and sets
The sealing at sealing firedoor frame reinforcement fire door is put, while setting smoke catching cover to collect from fire door above sealing frame escapes flue dust
Mode be controlled.But in actual production, usually because a variety of causes make it that the coal-charging smoke amount escaped from fire door is very big,
Seal firedoor frame sealing function limited, the smoke catching cover of top also can only collection portion exceptionally escape flue dust, most flue dust is still
So cannot effectively it control.
The content of the invention
The invention provides a kind of flow guiding type pusher side furnace door sealing device, for pusher side flue gas in carbonization chamber to be led from furnace roof
Air seal is carried out to pusher side fire door after the export of cigarette hole, the loss of coal-charging smoke can be effectively prevented, realized to tamping coke oven coal-charging
During flue dust effective control.
In order to achieve the above object, the present invention is realized using following technical scheme：
A kind of flow guiding type pusher side furnace door sealing device, including smoke guiding cover and pusher side oven door sealing frame；The smoke guiding cover is by leading

Sealing frame is movably docked with the sealing of coke furnace carbonization chamber both sides furnace stay；Energy after smoke guiding cover, the combination connection of pusher side oven door sealing frame
It is enough to form closing space with corresponding coke furnace carbonization chamber both sides furnace stay and fire door top headwall；It is close that pusher side oven door sealing inframe sets elasticity
Briquette both sides when sealing baffle with loading keep in sealing contact, at the top of briquette when sealing deflector is set in smoke guiding cover with loading
Keep in sealing contact.
The water conservancy diversion cover body is made up of preceding gas baffle, rear gas baffle, side panel, and the top of water conservancy diversion cover body and water conservancy diversion are curved
The bottom docking of pipe, the bottom of water conservancy diversion cover body is docked with pusher side oven door sealing frame.
The sealing deflector is located at smoke guiding cover bottom, and its width is identical with clear span in coke furnace carbonization chamber；Seal deflector
One end be hinged on the rear gas baffle of water conservancy diversion cover body, the other end is free end, when briquette loads, and sealing deflector can be around
The overall top into water conservancy diversion cover body of pin joint is rotated.
The sealing deflector is heat-resisting steel sheet and plate.
The pusher side oven door sealing frame is by support frame, seal, bottom plate, side plate, backboard and elastic packing baffle group
Into；Bottom plate is fixed on the bottom of support frame, and side plate is fixed on the both sides of support frame, and backboard is fixed on the outer of support frame
Side；The inner side of support frame is unenclosed construction, and its both sides passes through seal and the sealing pair of coke furnace carbonization chamber both sides furnace stay respectively
Connect；Elastic packing baffle is in the middle part of backboard, and it is, to opening structure, the side of opening structure to be hinged with backboard respectively.
The elastic packing baffle is the platy structure that heat-resistant elastic material is made, or to be configured with the resistance to of spring mechanism
Hot steel plate.
Compared with prior art, the beneficial effects of the invention are as follows：
1) by the smoke guiding cover with sealing deflector and the pusher side oven door sealing frame with elastic packing baffle, realize
Closing space is formed during coke oven coal-charging between sealing device and coke oven fire door, prevents the flue gas produced during coalingging from escaping, it is real
Now to effective control of tampering type coke oven coal-charging smoke；
2) by guide functions, the flue gas in sealing device is directed to inside carbonization chamber, realized to carbonization chamber fire door
Air seal is acted on, and promotes effective recovery of Coal charging flue gas, gas saving resource；The entrance of outside air is also prevented simultaneously,
Safety in production for coke oven gas gathering system and follow-up gas purification processing system provides effective guarantee.
