Instrument (two) pairing using be arranged on tail gas desorption tube, tail gas desorption tube from oil product storage tank draw access tail gas cleaning system into
Mouthful, after the tail gas air-introduced machine and pressure regulation instrument table (three) that the outlet of tail gas cleaning system is used by pairing are connect with gas piping
Directly connect coke oven distillation tube furnace；The safety valve draws the outlet of access tail gas cleaning system from tail gas desorption tube by pipeline
Afterwards, on the gas piping before tail gas air-introduced machine.
The tail gas air-introduced machine uses variable frequency adjustment formula air-introduced machine.
The control pressure of the pressure regulation instrument table (three) is lower than the control pressure of pressure regulation instrument table (two) 0.1~
0.3MPa。
Compared with prior art, the utility model has the beneficial effects that
1) each oil product storage tank is using the fuel gas of tar distillation tube furnace as sealing gas, and gas source is stablized, and coal
Gas coking tail gas is returned to gas piping after washing oil absorbs, and without any consumption, reduces expenses；
2) sealing system uses pressure Stability Design, i.e. pressure is lower than setting value, is adjusted by pressure-regulating valve (one) logical
Enter coal gas, pressure is higher than setting value, coal gas coking tail gas is discharged by pressure-regulating valve (two), but simultaneously, and increase coal all the way
Feed channel continuously enters dispersing gas system, it is ensured that pressure by flow control valve with the fixed flow lower than peak value
System is stablized, and fluctuation is reduced；
3) coal gas, coking tail gas after cleaning, are incorporated to the gas piping of tar distillation tube furnace, do not need to tar distillation
Tube furnace carries out any transformation, so that it may which safe is sent to tar distillation tube furnace safe combustion without generating any danger
Danger；
4) all tail gas include that the tail gas of safety valve discharge is passed to the innoxious burning of tar distillation tube furnace, energy conservation peace
Complete reliable environmental protection.
