Under non-discharge status, what electrically-controlled valve II was closed always, when air pressure leads to 9 pressure over-voltage of high pressure storage tank because of tail gas generation, just meeting
Vent gas treatment pipeline to be opened, overpressure gases are drawn, when carrying out vent gas treatment, i.e. discharging, electrically-controlled valve I 19, electrically-controlled valve III 18 are closed,
Electrically-controlled valve II is opened, by for pressure in I 20 autobalance slag cover 1 of nitrogen valve, 1 decompression of slag cover, by mending for nitrogen valve I 20
Pressure, until discharging stops；Discharge status go to non-discharge status, and electrically-controlled valve II is closed at this time, and electrically-controlled valve I 19 is opened, electrically-controlled valve
III 18 close, and because tar etc. uninterruptedly injects in slag cover 1, liquid level is increased in slag cover 1, and air pressure increases, and it is automatic to let out nitrogen valve 22
Balance slag cover 1 and I 11 pressure of pipeline are opened, when slag cover 1 and I 11 pressure of pipeline persistently increase, under pressure sensor monitoring
When hypertonia reaches setting value in slag cover 1, overpressure gases in pipeline I 11 are compressed into high pressure storage tank by the starting of gas compressor 8
9；When the pressure in high pressure storage tank 9 reaches setting value, the gas of the nitrogen envelope pressure maintaining of discharging is all recycled, electric at this time
It controls valve I 19 to close, electrically-controlled valve III 18 is opened, and the gas of over-voltage is drawn by vent gas treatment pipeline and carries out tail again in slag cover 1
Gas disposal.
Gas after extraction is transported in closed washing oil slot by blower, is introduced coke-oven plant's washing oil and is carried out oil to gas
It washes；Gas after washing oil is introduced into closed rinsing bowl (boiled water slot), is washed, and the washing oil in gas is removed；In washing oil slot
Washing oil washing tail gas after by pipeline introducing coke-oven plant dreg scraping trough, recycled；Gas after washing oil washing is re-introduced into water
Washing trough is washed, and the aqueous after washing gas passes through pipeline and introduces coke-oven plant's remained ammonia slot or introduce dreg scraping trough.
The above is only a preferred embodiment of the present invention, it is noted that for the those of ordinary skill of technical field
For, without departing from the principle of the present invention, several improvement can also be made, these improvement are not making the creative labor
Under the premise of also should be regarded as protection scope of the present invention.
