Description
Technical field
The utility model relates to the smoke gas treatment system in coke-oven plant's coke making process production process, relates in particular to a kind of smoke gas treatment system of leaking from tamping coke oven machine side furnace door.
Background technology
At present, a lot of tamping coke furnaces adopt the way of upcast high pressure aqua ammonia injection to reclaim raw gas when coalingging.Because gas recovery system has strict requirement to dust content and the oxygen level of raw gas; and the suction capactity that the high pressure aqua ammonia injection can produce is also limited; for the protection to the coking chamber jamb brick, generally also require in the faint malleation of pusher side stove gate place maintenance.Therefore, inevitable to the raw gas that external leakage contains dust at the stove gate place, the flue gas that leaks out from fire door is to contain a certain amount of combustiblecomponents (being called raw gas) and tar, as the flue dust of this part not being controlled and administered, must pollute environment; Simultaneously, this flue gas is in the course of conveying of pipeline, and tar can deposit in pipeline or the hanging tube wall, and easily causes and catch fire; When flue gas was sent to terrestrial station, tar also can be stuck with paste the cloth bag of sack cleaner, caused the sack cleaner can't works better.This administers the flue gas that leaks from tamping coke oven machine side furnace door with regard to needing a cover specific equipment.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model provides a kind of smoke gas treatment system of leaking from tamping coke oven machine side furnace door, avoid raw gas that environment is polluted, avoid tar to stick with paste the cloth bag of sack cleaner, influence the sack cleaner works better.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of smoke gas treatment system of leaking from tamping coke oven machine side furnace door, comprise smoke collection cover, main, main discharges of the coke, pre-duster, sack cleaner, the sweep-out mechanism plate, dust ash warehouse, blower fan, control device, smoke collection cover is arranged on the top of pusher side stove gate, between two furnace stays, smoke collection cover successively with main, main discharges of the coke, sack cleaner, the sweep-out mechanism plate, dust ash warehouse connects, sack cleaner also is connected with blower fan, flue gas after blower fan will be handled is discharged by chimney, described dust ash warehouse also is provided with humidifier, and described control device comprises PLC Controlling System and touch-screen.
Described PLC Controlling System is finished the data acquisition and processing (DAP) of collection and confinement of gases supervision, device control, equipment monitor, ash disposal winding-up control, coke powder collection supervision, failure message.
Compared with prior art, the beneficial effects of the utility model are:
Whole dust removal operation flow process is short, and system is simple, and equipment and materials is few, investment is little, avoids raw gas that environment is polluted, and has also avoided tar to stick with paste the cloth bag of sack cleaner simultaneously, guarantees that sack cleaner can works better.
Description of drawings
Fig. 1 is structured flowchart of the present utility model.
Fig. 2 is control device structured flowchart of the present utility model.
Embodiment
Below in conjunction with Figure of description the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1, Fig. 2, a kind of smoke gas treatment system of leaking from tamping coke oven machine side furnace door, comprise smoke collection cover, main, main discharges of the coke, pre-duster, sack cleaner, the sweep-out mechanism plate, dust ash warehouse, blower fan, control device, smoke collection cover is arranged on the top of pusher side stove gate, between two furnace stays, smoke collection cover successively with main, main discharges of the coke, sack cleaner, the sweep-out mechanism plate, dust ash warehouse connects, sack cleaner also is connected with blower fan, flue gas after blower fan will be handled is discharged by chimney, described dust ash warehouse also is provided with humidifier, and described control device comprises PLC Controlling System and touch-screen.
Described PLC Controlling System is finished the data acquisition and processing (DAP) of collection and confinement of gases supervision, device control, equipment monitor, ash disposal winding-up control, coke powder collection supervision, failure message.
Embodiment:
It discharges of the coke coke oven stove group and the operation of coalingging is not carried out simultaneously, therefore discharges of the coke and the dust collection for charging operating process can be switched by the butterfly valve that arranges on the main by a system, and earth station dust removing system of recycling is operated.
When the discharging of the coke operation, blower fan runs up and approaches and operates at full capacity, and blower fan is low-speed running after the operation of the discharging of the coke; And the operation of coalingging is to carry out after the operation of the discharging of the coke, and when operation of coalingging lacked from the exhaust gas volumn of the stove gate collection air quantity during than coke discharging and dedusting.
The utility model is exactly to utilize the low-speed running of blower fan after the operation of the discharging of the coke to finish the operation dedusting of coalingging.That is to say the speed change by blower fan, solve dust removal operation and system's control of two different exhaust gas volumns.
During the coke discharging and dedusting operation, blower fan runs up and approaches and operates at full capacity, filtering the coke powder that gets off by sack cleaner is covered with on the cloth bag surface, raw gas by smoke collection cover enters the main that discharges of the coke via switching butterfly valve, to sack cleaner, through the ash discharge of sweep-out mechanism plate, the dust ash is put into warehouse through pre-duster, through humidifier, by dust ash entrucking outward transport.Discharge behind blower fan, chimney through the gas after the dedusting of sack cleaner.
When coke discharging and dedusting is operated, filter the coke powder that gets off by sack cleaner and be covered with on the cloth bag surface.When coalingging when operation, these hang in the flue gas that coke powder on the cloth bag can prevent effectively that stove gate from leaking out contained tar and stick with paste cloth bag, have guaranteed the normal operation except ash manipulation.
When dust collection for charging was operated, though the exhaust gas volumn of required suction is few, the blast of blower fan can not be too low, otherwise can't effectively control dust-removal system.Smoke collection cover entrance above the pusher side stove gate will have enough suction, could guarantee that flue gas has certain speed when being inhaled into, and the flue dust that stove gate could be leaked out is processed fully.
Finish when operation of coalingging at the low-speed running that utilizes blower fan, the control of the flue gas that stove gate is leaked out and improvement because the reduction of the rotating speed of blower fan, the flow of its blower fan, total head have as shown in the formula variation relation, that is:
In the formula: Q1, n1, p1 are air quantity, rotating speed, the blast of coke discharging and dedusting operational stage; Q, n, p are air quantity, rotating speed, the blast of dust collection for charging operational stage.
When the flow of blower fan, total head, when rotating speed can not satisfy following formula, dust removal operation just can't normally be moved.
The utility model can be controlled the flue dust that stove gate leaks out, and makes combustiblecomponents in the flue gas not within limits of explosion, prevents that the tar etc. in the flue gas is bonded on the tube wall, avoids flue gas to catch fire in pipeline or explodes.Whole dust removal operation flow process is short, and system is simple, avoids raw gas that environment is polluted, and has also avoided tar to stick with paste the cloth bag of sack cleaner simultaneously, makes the sack cleaner can works better.
