The system comprises a cock discharge flue gas gathering shield, a cock discharge flue gas channel, a dust collection dry tube and a ground dust removing station which are hermetically connected in sequence, and is characterized in that a sealing structure mainly formed by a sealing groove, a sealing plate and sealing water is also arranged between the cock discharge flue gas channel and a port of the dust collection dry tube, wherein the sealing groove is formed parallel to the dust collection dry tube; the sealing plate is welded with the dust collection dry tube, and one end of the sealing plate extends into the sealing water to form a sealing space; and a moveable sliding tube is also arranged at the end of the cock discharge flue gas channel, which is connected with the dust collection dry tube. Compared with the prior art, the technical system has the advantages of low air leakage ratio, simple and scientific structure, convenience in fabrication, installation and maintenance, low investment cost and the like.
Description
Technical field
The utility model belongs to the dust separation device field, is specifically related to a kind of coke oven coke discharging and dedusting system.
Background technology
Coke oven is in the process of the discharging of the coke, and fervid red Jiao is released from coking chamber in order by pushing machine, and coke falls in the quenching car railway carriage by leading burnt grid.Fervid coke breaks, and burns in air after releasing from coking chamber, and the flue gas of generation and burnt dirt are dispersed in the air, and it is big to contain burnt dust quantity in this part flue gas, serious environment pollution.
At present, general flue gas special purpose interface valve and two kinds of capture modes of belt ventilation slot of the discharging of the coke that adopt of coke oven coke discharging and dedusting.But all there are many drawbacks in dual mode.
The drawback of interface valve mode mainly contains: 1. the existing interface valve all adopts silicon rubber or asbestos twine sealing, and long rubber of time one is by aging, and asbestos twine is left out, and system's air leak rate of air curtain strengthens; 2. the corresponding interface valve in every chamber, interface valve quantity is more, and the dust-removal system input cost is big; 3. interface valve open and close to adopt rotating mechanism, is easy to damage in the higher relatively and severe environment of rotating mechanism working accuracy; 4. the corresponding interface valve in every chamber, this chamber be interface valve and the very difficult location aligning fully that guarantees of coke guide upper connecting tube when the discharging of the coke.
The drawback of belt ventilation slot mode mainly contains: what 1. the belt ventilation slot mainly adopted is to drive the belt sealing by the rolling dolly, and system's air leak rate of air curtain is very big; 2. the dolly that rolls necessarily requires then that the plane reaches certain requirement on the ventilation slot rolling on the ventilation slot, and very long because of ventilation slot, reaching of having reaches more than 100 meter, and so long ventilation slot will guarantee its planeness, and then requirement on machining accuracy is higher.3. rolling dolly power resources are in coke guide on the ventilation slot, and the rolling dolly is easy to sideslip on ventilation slot, in case must proofread and correct again behind the rolling dolly sideslip, maintenance workload is bigger.
The utility model content
For overcoming above technological deficiency, the utility model provides a kind of good seal performance, coke oven coke discharging and dedusting system simple in structure.
Concrete technical scheme is:
This system comprises the flue gas trapping cover that discharges of the coke that is tightly connected successively, the exhaust gases passes that discharges of the coke, control of dust main and ground station for dust removal, it is characterized in that: this system also is provided with the sealed structure that mainly is made of sealing groove, sealing plate and sealing water between the interface of exhaust gases passes and control of dust main that discharges of the coke, wherein, sealing groove and control of dust main are arranged in parallel, sealing plate is with the welding of control of dust main, one end stretches in the sealing water, forms seal cavity.
The section of described sealing groove is " U " font, because of long-time splendid attire sealing water in the sealing groove, so each commissure must be tight.Can adopt the 6mm steel plate to be welded.
Be provided with water drain valve for being convenient for changing the described sealing groove of sealing water bottom.
The end that exhaust gases passes and control of dust main join that discharges of the coke is provided with mobile slip pipe, and this moves slip pipe and is connected with the exhaust gases passes that discharges of the coke by flange.Mobile slip pipe is the major parts of present technique, and mobile slip pipe is connected with the exhaust gases passes that discharges of the coke, fume trap cover by flange, slides in sealing groove by the motion of coke guide.Mobile slip pipe can adopt the SU304 material to make, and is the resistance that reduces to slide in sealing groove, and the position corresponding with sealing groove, the end of mobile slip pipe done in the arc-shaped.
Described control of dust main adopts section " C " font structure, and C shape opening part adds band steel and steel pipe as stay bolt.The main effect of stay bolt is in order to strengthen intensity, is out of shape at opening part after the shaped sections that prevents that the main of a rounded section is processed into " C ".
With respect to prior art, the advantage of present technique is mainly reflected in:
1. the interface of burnt exhaust gases passes and control of dust main is provided with the watertight sealing groove, and stopping property improves, and the system air leak rate of air curtain of making reduces significantly.
2. the science simple in structure of the utility model system, fabrication and installation are easy to maintenance, save input cost.
Description of drawings
Fig. 1 is the structural representation of the utility model preferred embodiment.
Fig. 2 is the cross section structure figure of Fig. 1 sealing groove.
Fig. 3 is the sectional view of Fig. 1 control of dust main and sealing plate structure.
Embodiment
Below in conjunction with embodiment the utility model is further described.
As shown in Figure 1, present embodiment comprises the flue gas trapping cover 1 that discharges of the coke, the exhaust gases passes 2 that discharges of the coke, mobile slip pipe 6, sealing groove 3, control of dust main 4 that connects successively and the ground station for dust removal that is connected with control of dust main 4.As shown in Figure 2, sealing groove 3 is " U " shape, and sealing groove 3 is arranged in parallel with control of dust main 4.As shown in Figure 3, control of dust main 3 is provided with " C " shape opening 41, opening 41 place's welded seal plates 5, and sealing plate 5 is made of two vertical steel plates, and an end is welded on the control of dust main 4, and an end stretches in the sealing water 7." C " font opening part is provided with stay bolt 42.
Its mode of operation is:
The flue gas trapping cover 1 that discharges of the coke is fixed on the coke guide, when discharged of the coke in certain carbonization chamber, the flue gas trapping cover 1 that discharges of the coke moves on to this end, carbonization chamber and makes the center, burnt grid centrally aligned carbonization chamber of leading, coke is released from coking chamber, by the effect of ground station for dust removal blower fan negative pressure, the flue gas that discharges of the coke enters ground station for dust removal by fume trap cover 1, mobile slip pipe 6, control of dust main 4.After the discharging of the coke and finish in one Room, mobile slip pipe 6 is followed coke guide and is moved to specified location and await orders and enter next carbonization chamber and discharge of the coke.
