Abstract

The utility model is related to a kind of movable pumping dust hood of coke oven fire door, the flue gas generated when for trapping coke oven production.It is characterized in that, the pumping dirt mouth of three different air quantity is arranged in the present apparatus, exhausting targetedly is carried out to flue dust point at three, each dirt mouth of taking out sets movable smoke baffle again, movable smoke baffle is overlapped with fixed smoke barrier when work, effectively inhibit flue gas effusion problem the dust arrestment rate of coke oven fire door can be made to reach 95% or more using the present apparatus.

Description

A kind of movable pumping dust hood of coke oven fire door

Technical field

The utility model is related to coke oven fire doors to take out dirt technical field, can be applied to all kinds of coke-oven dust removing systems.

Background technology

Coke oven fire door flue gas source mainly has at three, one is flat coal operation mouth, the second is main operation mouth, the third is bell Place, this exhaust gas volumn at three is different, and respectively has a distance.Conventional pumping dirt mouth is unreasonable due to designing, and influences coke oven life Production, and must cause the flue gas that fire door generates that cannot be pumped completely there are enough gaps, have since pusher machine needs to walk A large amount of flue gas effusion, flue gas trapping rate are relatively low.

Invention content

In view of the above-mentioned problems, the utility model carries out various aspects innovation, this pumping dust hood can realize flue dust mouth at three while take out Dirt, and by the combination of fixed smoke barrier and movable smoke baffle, effectively avoid the problems such as flue gas escapes.

One side according to the present utility model provides a kind of movable pumping dust hood of coke oven fire door, living by fixed smoke blocking board Dynamic smoke blocking board, movable rod, flat coal take out dirt mouth, main pumping dirt mouth, and bell takes out dirt mouth, and set exhaust column is constituted.

In coke oven production, there is flat coal to take out dirt mouth, main pumping dirt mouth, these three pumping dirt mouths of bell pumping dirt mouth correspond to coke oven three The position that smolders carries out pumping dirt.

On the basis of said program preferably, the fixed smoke blocking board is integrally fixed above coke oven fire door.

On the basis of said program preferably, the activity smoke blocking board can be opened or be closed under the action of movable rod Leak cigarette gap.

On the basis of said program preferably, the set exhaust column is fixed on by exhaust column on pusher machine, can be with pushing away Burnt vehicle synchronous walking.

For coke oven fire door flue dust output situation, the present apparatus sets three pumping dirt mouths and carries out pumping dirt altogether, each air quantity for taking out dirt mouth It is different.

Problem is escaped for flue gas, each take out is equipped with movable smoke baffle at the top of dirt mouth, can be opened under movable rod effect And closing, pusher machine walking and fire door operation are not influenced, while effectively preventing flue gas from escaping.

Flow deflector and airflow-distribution board are set in set exhaust column, it is ensured that the air quantity of three pumping dirt mouths reaches design requirement And it balances.

Description of the drawings

Fig. 1 is the structural schematic diagram of the present apparatus.

Specific implementation mode

Below in conjunction with the accompanying drawings and specification, the specific implementation mode of the present apparatus is described in further detail.

As shown in Figure 1, the movable pumping dust hood of coke oven fire door is put down by fixing smoke blocking board 1, movable smoke blocking board 2, movable rod 3 Coal takes out dirt mouth 4, main pumping dirt mouth 5, and bell takes out dirt mouth 6, and set exhaust column 7 is constituted.

As shown in Figure 1, fixed smoke blocking board 1 is arranged above coke oven mouth, this smoke barrier is fixed on coking furnace shaft.

The flue dust that coke oven generates takes out dirt mouth 4 by flat coal respectively, and main pumping dirt mouth 5, bell pumping dirt mouth 6, which is taken away, converges to set Exhaust column 7, then access external dust pelletizing system air hose and carry out purified treatment.

Movable smoke blocking board 2 is separately fixed at flat coal and takes out dirt mouth 4, main pumpings dirt mouth 5, and bell takes out dirt mouth 6, by activity company when work For bar 3 by its pull-up, respectively take out has enough gaps at this time between dirt mouth and coke oven, ensures unaffected when pusher machine walking.Work as pusher machine Stop start operation when, movable rod 3 puts down movable smoke blocking board 2, and is overlapped on fixed smoke blocking board 1, closing between the two Gap, flue gas will not escape when exhausting.

All of above description is the preferable application example of the utility model, but the scope of protection of the utility model is not It is confined to this, any technical staff within the scope of this technical field, the variations and alternatives that can be readily occurred in, which should all cover, is protecting Within the scope of shield, thus, the scope of protection of the utility model should be subject to the protection domain that claim defines.
