Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing:
As shown in Figure 1-Figure 3, a kind of water-sealed valve dish structure single hole carbonization chamber pressure regulating system described in the utility model,
Thallium 3, variable diameter bridge tube 4, water-sealed valve 5, water seal valve disc 6, ammonia spray nozzle 7 and pressure measuring system 8 are adjusted including cylinder 1, pull rod 2, flow,
The intermediate position of the variable diameter bridge tube 4 is designed as the truncated cone shape that top section is small, lower part section is big, and flow adjusts thallium 3 and installs
It inside variable diameter bridge tube 4, is connect by pull rod 2 with cylinder 1, the upper and lower flexible regulating flow quantity of cylinder 1 adjusts thallium 3 in variable diameter bridge
Position in pipe 4 changes the circulation section of raw coke oven gas, achieve the purpose that stablize charing room pressure；Exist when flow adjusts thallium 3
When moving from bottom to top in variable diameter bridge tube 4, from large to small, the circulating resistance of raw coke oven gas is then by small change for the circulation section of raw coke oven gas
Greatly；Conversely, the circulation section of raw coke oven gas changes from small to big, waste when flow adjusts thallium 3 and moves from top to bottom in variable diameter bridge tube 4
The circulating resistance of coal gas is then from large to small.The water-sealed valve 5 is connect with the lower part of variable diameter bridge tube 4 by socket joint, 7 He of ammonia spray nozzle
The top of variable diameter bridge tube 4 is arranged in pressure measuring system 8；The water seal valve disc 6 and water-sealed valve 5 are hinged, can be around the rotation a of hinge joint 61
It is 75~85 °.
The measured value chain control of the actuating length of the cylinder 1 and pressure measuring system 8, the measured value of pressure measuring system 8 can be with
Reflection carbonizes indoor pressure, and cylinder 1 can adjust the position of thallium 3 according to the pressure measuring value flow automatic regulation of pressure measuring system 8
It sets, to change the circulating resistance of raw coke oven gas, achievees the purpose that stablize charing chamber pressure.
When work, the raw coke oven gas that coke oven generates flows downward after entering variable diameter bridge tube 4 from raw coke oven gas entrance, passes through water-sealed valve
5 export away the gas collecting tube constant into pressure from raw coke oven gas.
1) during coking, occurrence quantity of the raw coke oven gas generated according to coke oven during entire coking is from large to small
, in order to stablize the indoor pressure of charing, the circulating resistance of raw coke oven gas must be with the variation of raw coke oven gas yield and by small change
Big principle, the pressure value that the pressure measuring system 8 by being mounted on 4 top of variable diameter bridge tube measures, timely automated about 1 adjusting cylinder
Stroke, cylinder 1 drive flow adjusting to stick together and 3 move up and down to corresponding position by pull rod 2, to change the circulation resistance of raw coke oven gas
Power carbonizes indoor pressure (at this point, water seal valve disc 6 is normally opened) to stablize；
2) a large amount of flue dust can be generated when coalingging to carbonization chamber, water seal valve disc 6 is opened at this time, and flow adjusts thallium 3 and is in
The circulation section of the lowest part (fully open position) of variable diameter bridge tube 4, raw coke oven gas is maximum, can make to carbonize indoor raw coke oven gas and lead rapidly
Out；
3) coking latter stage in order to remove the graphite of at the top of carbonization chamber and tedge root, needs to open on tedge lid, this
When water seal valve disc 6 close, flow adjusting sticks together 3 in upper portion (full close position), and ammonia spray nozzle 7 sprays ammonium hydroxide in water seal valve disc
Water seal is formed in 6, is cut off the circulation of raw coke oven gas, that is, is cut off the connection of gas collecting tube and atmosphere.
