Further, described voltage stabilizing pipeline is also provided with secondary glasses valve and electric gate valve, glasses valve is lightweight, volume is little, easy to operate, be swift in motion, to cut off gas performance definitely reliable, make the function point analysis of coal gas voltage stabilizing retrieving arrangement reliable and stable, there will not be the situation of gas leakage.
Further, described recovery channel is also provided with butterfly valve and the second variable valve at the back segment in region in parallel with voltage stabilizing pipeline, butterfly valve main rising on recovery channel is cut off and throttling action, second variable valve plays Secondary Control effect, guarantee the coal gas of converter pressure-stabilisation between furnace carriage, and make unnecessary coal gas of converter efficient recovery.
Further, described main valve adopts electric butterfly valve, and control simple and fast, work reliability is high.
The caliber of described voltage stabilizing pipeline is less than the half of converter gas pipeline caliber, and make when reclaiming unnecessary coal gas of converter, the pressure being supplied to the coal gas of converter between furnace carriage can not fluctuate excessive, regulates more steady to the pressure of the coal gas of converter be given between furnace carriage.
Further, the caliber of described converter gas pipeline is DN1200, and the caliber of voltage stabilizing pipeline is DN500.
Compared with prior art, the utility model advantage is:
Coal gas voltage stabilizing retrieving arrangement described in the utility model by unnecessary RECOVERY OF CONVERTER GAS, can ensure again the pressure-stabilisation of coal gas of converter in the situation that coal gas of converter is unnecessary, thus ensures to use coal gas of converter between furnace carriage, finally reaches the object of save energy.
