Background technique
Gas pressure in coke oven is varied widely with the different coking phases, and when just coalingging, gas volume increases, institute
With gas pressure highest, at this moment gas leak will be caused because pressure increases at stoke hole and fire door, to prevent coal gas from leaking,
It is artificial mostly at coal gas concetrated pipe to cause negative pressure, but with the progress of coking process, gas volume gradually tails off, pressure again gradually
Be lower, but because the negative pressure of concetrated pipe is constant, at this moment again may make occur negative pressure in furnace, coal filling hole and fire door etc. will because sealing
It is not tight and make air sucking furnace in, increase the combustion loss of coking coal, destroy gas quality, will likely set off an explosion thing when serious
Therefore for this problem, domestic and international many producers are all taking appropriate measures, and keep furnace pressure balance, the method for solution:
Some sprays high pressure water again at manifold inlet and penetrates negative pressure to form suction, exhaust is assisted when gas volume is big, but it needs people
Work operation, and its corrective action is difficult with gas pressure and is changed；In addition the self-con-tained unit of various modes is also taken
It is adjusted, such as installs electric and pneumatic adjusting line additional, using its aperture of furnace pressure signal feedback control, this method is relatively more suitable
With, but investment is too big, and every coke oven wants hundreds of thousands first, and in addition maintenance difficulties also increase accordingly.
Such as a kind of coal gas pressure retaining disclosed in Chinese patent CN201395571, the coal tar producer gas pressure stabilizing
Valve, although adjusting the gas pressure in coal gas tedge by the gravity with heavy lead, being automatically maintained at the pressure in coke furnace
The range of setting, that is, accident potential caused by can guarantee coke oven normal operation and can avoid because of pressure anomaly, the pressure stabilizing valve arrangement
Simply, easy to maintain, still, the coal gas pressure retaining, existing can not be in sighting tube body the shortcomings that pressure.
