Description
Technical field
This technology is typically directed toward the apparatus and method for for adjusting pipeline fluid flow inside.More specifically, certain specific
Embodiment is related to improving the flow conditioner and transition portion of the exhaust gas being discharged from coke oven flowing by pipeline monitor device.
Background technique
Coke is a kind of solid carbonaceous fuels from coal.Due to its relatively small number of impurity, coke is in various realities
With being all welcome energy sources in purposes.For example, coke often be used to smelt iron ore in steelmaking process.Another
In a example, coke can also be used to heating commercial building or drive Industrial Boiler.
In typical coke making process, a large amount of coal is fired in coke oven, and temperature therein is usually more than 2000
Degrees Fahrenheit.The relatively high coal of impurity is transformed into the coke containing relatively fewer impurity by sintering procedure.At the end of sintering procedure,
Coke usually appears in coke oven in generally complete one piece of form.Coke is removed from coke oven usually, is packed into one
A or multiple compartments (for example, hot carrier vehicle compartment, quenches compartment, or hot load/quenching compartment of combination), and quenching tower is transported to it
Cooling or " quenching ", can transport dispatching, use as fuel source.
Hot waste gas (such as flue gas) is discharged from coke oven by the network being made of pipeline, intersection and transition apparatus.
Skewing mechanism in the flow of flue gas path of coke plant can lead to serious pressure drop penalty, inefficient flow region (such as
It is static, stagnate, reflux, separation etc.) and air and volatile materials poor mixing.High pressure decline loss causes higher
It is required that draft, this can further result in leakage and more uncontrollable system.In addition, due to the local erosion of acceleration
And thermal wear, the local hot spot of poor mixing and generation can cause faster structural degradation.Erosion includes due to high velocity stream
It is dynamic to corrode caused material property decline.Heat spot can cause the thermal degradation of material, eventually lead to hot/structural failures.This
One local erosion and/or heat spot can transfer the damage for leading to pipeline monitor.For example, the exhaust uptake and cross pipeline of coke-oven plant
Infall be easy to be influenced by the distribution of poor mixing/air-flow, the generation of heat spot can be caused, further result in channel mistake
Effect.
Traditional pipeline monitor design also results in serious pressure drop penalty, this loss can be limited in single group
The quantity of the coke oven connected together.The draught fan of coke-oven plant can drive great draft, and there is also limitations.Pipeline
Pressure decline in skewing mechanism can reduce the available draft amount for flue gas is discharged in coke oven battery.
The these and other problem related to traditional pipeline monitor design will lead to additional capital expense.Therefore,
There is it is such need to provide pipeline monitor/transition apparatus of improvement, such device can improve the mixing of gas, air-flow
It spreads, is minimized inefficient flow region (such as static, stagnation, reflux, separation etc.), and the decreasing loss in the case where infall reduces pressure
It loses, so as to improve the running and potentially reduction design, the cost of construction and operation coke-oven plant of coke-oven plant.

Personnel can correspondingly understand that this technology may be present other embodiments with additional element or this technology and may be present not and have ginseng
Examine the other embodiments of some features of institute's showing and describsion in following figure 1-14.
Shown in FIG. 1 is a typical coke-oven plant, wherein coal 1 is admitted to coke oven battery 10, leads in coke oven battery
It crosses heating coal and obtains coke.The exhaust gas (such as flue gas) being discharged from coke oven is logical in sharing for intersecting with emergency exhaust pipe 14
It is collected in road 12.Crossing pipeline 16 is connect also by emergency exhaust pipe 14 with common-use tunnel 12.Hot fume passes through crossing pipeline 16
Cogeneration power plant 18 is flowed into, which includes the waste heat boiler (HRSG) 20 for supplying steam turbine 22 in turn.These flue gases
Continue to flow into sulphuring treatment facility 24.Finally, treated, and exhaust gas is discharged via pipeline fan 26 by main exhaust 28.In addition to logical
It crosses main exhaust 28 to rise other than the air-flow of gas generation of discharge, which provides negative pressure for whole system.
It can understand that coke oven 10 is to be connected to shared pathway 12 by upcast 15 with further reference to Fig. 2.Common-use tunnel
12 extend along the top horizontal of coke oven 10.Exhaust pipe 14 of meeting an urgent need extends along common-use tunnel 12 vertically as shown in the figure.Across
Pipeline 16 is in emergency exhaust pipe 14 in pipeline monitor device 30 and intersects.In normal operation, emergency exhaust pipe 14, which is in, closes
State, and exhaust gas flows into cogeneration power plant 18 by crossing pipeline 16 (referring to Fig. 1).When cogeneration power plant 18 or it is other after
When problem occurs for the equipment in stage, emergency exhaust pipe 14 can be opened, so that exhaust gas be allowed to be expelled directly out.Although shown in figure
Common-use tunnel 12 and crossing pipeline 16 and emergency exhaust pipe 14 intersect at different height, but common-use tunnel 12 and crossing pipeline 16
Identical height can also be intersected at emergency exhaust pipe 14.In addition, disclosed technique can be used for no matter it is in identical height
Or the skewing mechanism of different height.
It is shown in Fig. 3 to occur from traditional pipeline monitor device, such as pipeline monitor device 30, in various flowings it is different
Often.Flow abnormalities 32 are the partial combustion points due to caused by inefficient flowing/distribution.Another inefficient flowing/mixing dispersion zone
36 are located in the emergency exhaust pipe 14 at crossing pipeline 16.Inefficient flow region 34 (such as it is static, stagnate, reflux, separation
Deng) be located in crossing pipeline 16.These inefficient flow regions contain the gas flowing of separation, can consume the useful energy of flow.
These potential inefficient flowing spaces also can include unwanted, unstable vortex.These vortex sometimes can be because of buoyancy
Or chemical reaction and enhance, can lead to unwanted, the undesirable sound, forced harmonic wave, potential flow instability,
And incorrect meter reading.If inefficient flow region under the conditions of not having gas in pipelines and flowing representative carries out
Measurement, incorrect meter reading may can occur.Because the essence of these inefficient flow regions is in this way, these regions
It can cause falling and promoting particle packing for particle.
