Abstract
The present invention relates to a kind of coke oven power smoke evacuation system, including coke oven, coke oven chimney, smoke eliminator and blower fan；It is connected between the coke oven and coke oven chimney by flue collector, is set on the flue collector of coke oven and smoke eliminator is set on blower fan, the flue collector or by-pass flue in blower fan downstream, smoke eliminator and blower fan independent control.After the present invention, coke oven discharges fume process all the time by blower fan offer power, and coke oven chimney so that avoiding the production cost caused by flue gas heats up again after coke oven chimney is hot standby or purifies increases, and ensures the continuous-stable of coke oven smoke evacuation without hot standby.
Description
Technical field
The present invention relates to coke oven technical field, more particularly to a kind of coke oven power smoke evacuation system.
Background technology
Coke oven smoke evacuation system is directly to connect coke oven with coke oven chimney by flue collector, and coke oven flue gas is in coke oven chimney
Under suction, from coke oven, enter coke oven chimney through flue, directly discharge.In order to ensure the suction of coke oven chimney, coke oven chimney is from baking
Heater stage is started to warm up, until going into operation, is included in follow-up normal productive process, is needed to maintain more than certain temperature all the time,
That is " hot standby ".All the time, coke oven chimney " hot standby " has become the Normal practice of coke oven flue gas discharge, nearly all and coke oven
The related technique of flue gas can not all break away from coke oven chimney " hot standby ".
Environmental administration issue relevant emission standards after, coal chemical enterprise by smoke eliminator to coke oven flue gas at
Reason, but still adopted the fume exhausting type of coke oven chimney " hot standby "；As shown in figure 1, smoke eliminator 5 is generally arranged at coke oven
On by-pass flue 6 between 1 and coke oven chimney 2, flue gas is introduced by smoke eliminator 5 by blower fan 4, then again through coke oven cigarette
Chimney 2 is discharged；Flap valve 7 is set on flue collector 3, no matter flue gas discharges from flue collector or from by-pass flue after smoke eliminator
It is both needed to the negative pressure by " hot standby " generation of chimney.Because the temperature after gas cleaning is likely to be less than " hot standby " temperature, it is necessary to
Flue gas after purification is heated up again；And in operation time periods such as smoke eliminator maintenance, blower fan will be out of service, and coke oven is still
It need to be discharged fume by " hot standby " of coke oven chimney.
The content of the invention
The invention provides a kind of coke oven power smoke evacuation system, coke oven smoke evacuation process provides power by blower fan all the time, burnt
Stove chimney need not be hot standby, so that avoiding the production cost caused by flue gas heats up again after coke oven chimney is hot standby or purifies increases,
And ensure the continuous-stable of coke oven smoke evacuation.
In order to achieve the above object, the present invention is realized using following technical scheme：
A kind of coke oven power smoke evacuation system, including coke oven, coke oven chimney, smoke eliminator and blower fan；The coke oven with
It is connected between coke oven chimney by flue collector, blower fan, the flue collector or branch's cigarette in blower fan downstream is set on the flue collector of coke oven
Smoke eliminator, smoke eliminator and blower fan independent control are set on road.
The blower fan is at least 2, and one works, and remaining is spare unit.
When the smoke eliminator is on by-pass flue, close to flue collector and the main cigarette of by-pass flue upstream connectivity part
Control valve is set respectively on road and by-pass flue.
Compared with prior art, the beneficial effects of the invention are as follows：
1) constraint that coke oven smoke evacuation fully relies on the heat buoyancy that chimney " hot standby " is produced afterwards has been broken away from, has been coke oven smoke evacuation technique
Open one's minds；
2) in the case where setting up cock-oven gas purifying device, without considering that the flue gas after purification heats up again, coke oven chimney
Without " hot standby ", only by raising fan outlet pressure, you can overcome flue gas purification system resistance, realize smoke evacuation process；
3) avoiding the production cost caused by flue gas heats up again after coke oven chimney is hot standby or purifies increases, and ensures coke oven
The continuous-stable of smoke evacuation.

Embodiment
The embodiment to the present invention is described further below in conjunction with the accompanying drawings：
A kind of coke oven power smoke evacuation system of the present invention, including coke oven 1, coke oven chimney 2, smoke eliminator 5 and wind
Machine 4；It is connected between the coke oven 1 and coke oven chimney 2 by flue collector 3, blower fan 4, blower fan 4 is set on the flue collector 3 of coke oven 1
Smoke eliminator 5, smoke eliminator 5 and the independent control of blower fan 4 are set on the flue collector 3 or by-pass flue 6 in downstream.
Described that flap valve is additionally provided with the flue collector 3 of coke oven 1, blower fan 4 is located at the downstream of flap valve.
The blower fan 4 is at least 2, and one works, and remaining is spare unit.
When the smoke eliminator 5 is on by-pass flue 6, close to flue collector 3 and the upstream connectivity part of by-pass flue 6
Control valve 7 is set respectively on flue collector 3 and by-pass flue 6.
As shown in Fig. 2 blower fan 4 is placed on flue collector 3 and positioned at the upstream of smoke eliminator 5 by the present invention, blower fan 4 with
Smoke eliminator 5 is controlled respectively, and during normal gas cleaning discharge, the power produced by blower fan 4 leads to flue gas from coke oven 1
Smoke eliminator 5 is handled and discharged eventually through coke oven chimney 2, and coke oven chimney 2 is without hot standby.When smoke eliminator 5 goes out
When existing failure or maintenance, the normal work of blower fan 4, flue gas is passed through by the branch line of smoke eliminator 5, and via coke oven chimney
2 discharges, so as to ensure the service pressure of coke oven 1.
As shown in figure 3, being another concrete form of the present invention, blower fan 4 is placed on flue collector 3 and positioned at gas cleaning dress
Put 5 upstream, blower fan 4 controlled respectively with smoke eliminator 5, and smoke eliminator 5 is placed on by-pass flue 6；Normal flue gas
During purification discharge, the control valve 7 on by-pass flue 6 is opened, and flue gas is led to cigarette by the power produced by blower fan 4 from coke oven 1
Air purifying apparatus 5 is handled and discharged eventually through coke oven chimney 2, and coke oven chimney 2 is without hot standby.When smoke eliminator 5 occurs
When failure or maintenance, the normal work of blower fan 4 closes the control valve 7 on by-pass flue 6, opens the control valve on flue collector 3
Door 7, flue gas is directly passed through by flue collector 3, and is discharged via coke oven chimney 2, so as to ensure the service pressure of coke oven 1.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
