Description
Technical field
The utility model relates to coke oven for iron Operation and Maintenance equipment field, relates in particular to a kind of coke furnace carbonization chamber furnace wall graphite and purges instrument.
Background technology
In the daily production process of coke oven, on the coke furnace carbonization chamber furnace wall, can generate one deck graphite.When furnace wall graphite is blocked up, can causes that coke pushing current is excessive, even cause the generation of difficult coke pushing accident, and then influence coke oven production stable and work-ing life.To the removing of furnace wall graphite, the method that in coking enterprise, adopts blowpipe to purge usually.As shown in Figure 1, promptly in coking chamber, be blown into pressurized air from coal filling hole or fire door with compressed air spraying pipe 1 after the coke pushing, to burn the graphite that adheres to.Compressed air spraying pipe 1 is generally 4 fens steel pipes that internal diameter is 22mm, and its afterbody is connected with compressed air line 1a with flexible pipe 1b.Oxidizing reaction (burning) can take place in oxygen and graphite (carbon), and the method for using said apparatus to purge utilizes this principle to remove graphite.
But the oxidizing reaction temperature influence between oxygen and the graphite (carbon) is bigger, and relation as shown in Figure 2 between speed of reaction of the two and the temperature.As can be seen from Figure 2, when residing temperature reaches more than 900 ℃, reaction between graphite and the pressurized air is just slightly obvious, so method of using original device to purge, exactly normal temperature air is blown top layer to graphite, this not only is difficult to make its temperature of reaction to reach the ideal situation, but also can make the surface temperature of graphite reduce further because of cooling effect, and the reaction of removing graphite is difficult to continue, carries out effectively.In fact, the removing graphite effect that is embodied in the former method mainly is after the graphite skin temperature returns to more than 1000 ℃, react again by oxygen and graphite in the air that is trapped in graphite surface and to finish, and be not because pressurized air is blowed directly to react to the graphite top layer finishes.Therefore, the use said apparatus is removed low, the poor effect of efficient of graphite, especially is in opening-wide state at fire door to be, and is long partially to the time that burner graphite purges, and will cause the damage of body of heater bigger; And when coke oven was produced with high working rate tissue, its efficient was lower, so the influence that coke oven is produced is also bigger.
Summary of the invention
The purpose of this utility model provides a kind of purging instrument of coke furnace carbonization chamber furnace wall graphite, be used for finishing the graphite that adheres on the post-purge coking chamber wall, cause because of the graphite of coke furnace carbonization chamber furnace wall and pressurized air combustion reactions are insufficient to solve in the prior art that its elimination efficiency is low, the problem of removing poor effect at pushing coke operation.
Technical conceive of the present utility model is as follows: can carry out texture improvement to existing coke furnace carbonization chamber furnace wall graphite purging instrument according to aerodynamic principle, and set up mixing air winding-up pipe, warm air suction port, pressurized air targeting port and compressed air pressure setting device.Wherein, the caliber of mixing air winding-up pipe should be greater than the caliber of compressed air spraying pipe, and the two connecting portion can adopt the adapter bonnet mode of connection; The warm air suction port is located at the adapter bonnet position, and it can be designed to spirrillum hydraucone, poroid or similar structure formation.Device after using improvement is when coking chamber wall graphite surface winding-up pressurized air, the compressed air guide mouth of this pressurized air, near the formation negative pressuren zone warm air introducing port, thereby can import warm air in the coking chamber simultaneously by the warm air introducing port, above-mentioned cold and hot air can make the air themperature that purges to graphite surface raise significantly after mixing, thereby can improve the speed of reaction of purging air and graphite.Particularly, adopt the trumpet-shaped warm air suction port of spiral, the turbulent extent the when warm air that can increase suction mixes with normal temperature air, thereby raising mixing air temperature; Adopt poroid warm air suction port, then simple in structure, and be easy to processing and manufacturing.
The purpose of this utility model is achieved in that a kind of coke furnace carbonization chamber furnace wall graphite purges instrument, comprise the compressed air spraying pipe, also comprise: mixing air winding-up pipe, its caliber is greater than the caliber of described compressed air spraying pipe, and is installed in the front end of this compressed air spraying pipe through an adapter bonnet; At least one warm air suction port, it is poroid and is opened on the described adapter bonnet; And a pressurized air targeting port, it is the open circles taper and is fixedly arranged on described adapter bonnet inside.
Preferably, this coke furnace carbonization chamber furnace wall graphite instrument that purges also comprises a compressed air pressure setting device that is installed in described compressed air spraying pipe rear end.
Preferably, described compressed air pressure setting device comprises an at least one tensimeter and a reducing valve.
Preferably, the exit end of described warm air suction port and described pressurized air targeting port is in same level height.
Preferably, described warm air suction port is arranged with a plurality of on described adapter bonnet, and is provided with in the outside of this warm air suction port and is the protuberance that hollow hydraucone is gradually opened shape.
Preferably, described warm air suction port is arranged with a plurality of on described adapter bonnet.
The utility model is owing to adopted above technical scheme, make it compared with prior art, have the following advantages and positively effect: the purging instrument of this coke furnace carbonization chamber furnace wall graphite, the compressed air temperature of jetting can be effectively promoted, thereby elimination efficiency, the good removing effect of realization of graphite can be improved significantly to graphite surface.Because being all coke ovens, coke furnace carbonization chamber furnace wall calculus China ink all is difficult to a kind of phenomenon of avoiding, especially at home, because of furnace wall silica brick surface flatness poor, so the phenomenon of its calculus China ink is even more serious, die the utility model applicable to all coking enterprises, the practical value height.
