Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further:
As shown in Figure 1-Figure 3, a kind of coke oven single hole carbonization chamber pressure-regulating device described in the utility model, including being arranged on
Water seal valve disc 7 in bridge tube 2；Also include pressure-measuring pipe 6 and actuator 9；Described pressure-measuring pipe 6 is installed by pressure-measuring pipe guide pin bushing 5, surveys
Pressure pipe guide pin bushing 5 is fixed on bridge tube wall, and pressure-measuring pipe 6 stretches in bridge tube 2 through pressure-measuring pipe guide pin bushing 5, and inserting end is in ammonia
In the spraying range of nozzle 4；Actuator 9 is arranged on discharge operating board 10 or discharge 3, and the power of actuator 9 is defeated
Go out end to be connected with the moving rod 8 of water seal valve disc；Pressure-measuring pipe 6 and actuator 9 are all connected with computer control system.
Described pressure-measuring pipe guide pin bushing 5 and pressure-measuring pipe 6 are by Flange joint, and pressure-measuring pipe guide pin bushing 5 can by screw thread with bridge tube 2 tube wall
Releasably connect, or connect so that welding manner is fixing.
Described actuator 9 is the one in cylinder, hydraulic cylinder, electric cylinder or electro-hydraulic cylinder.
As shown in Figure 1 or 2, coke furnace carbonization chamber raw coke oven gas out is collected through tedge 1, and temperature is up to 700 750
DEG C, spray the way of ammonia, after making raw gas temperature be reduced to 80 100 DEG C, warp in being typically employed in bridge tube 2 and discharge 3
After discharge 3 to recovery workshop processes further, more outwards carry.
During as it is shown on figure 3, this utility model increases pressure-measuring pipe guide pin bushing 5 on bridge tube 2, can be in bridge tube 2 outer wall perforate, then
Pressure-measuring pipe guide pin bushing 5 is fixed on tapping.Concrete connected mode can be tapping and pressure measurement on bridge tube 2 wall of bridge tube 2 tapping
