Embodiment 1
[0023] Such as figure 1 As shown, the present invention is applicable to a direct recovery device for industrial large flow rate and large adjustment ratio flare gas, which includes a flare gas pipeline network 1, and the flare gas sent from the flare gas pipeline network 1 is divided into two paths, and one path is connected to the gas The inlet of cabinet 8, and the other gas connection to the inlet of separator tank 2;
[0024] The outlet of the gas cabinet 8 is connected to the inlet of the compressor unit 9, and the outlet of the compressor unit 9 is connected to the fuel gas pipeline network 10; A self-control valve 7 is provided on the connection pipeline between the flare gas pipeline network 1 and the inlet of the gas cabinet 8 , an automatic control valve is provided on the connection pipeline between the outlet of the gas cabinet 8 and the compressor unit 9 , and a manual valve 6 is provided on the fuel gas pipeline network 10 .
[0025] The outlet of liquid separa...
Embodiment 2
[0028] Adopt a kind of device described in embodiment 1 to be applicable to the direct recovery method of industrial large flow, large adjustment ratio flare gas, specifically as follows:
[0029] The torch gas sent from the torch gas pipeline network 1 is divided into two paths, one path of gas can be transported to the gas cabinet 8, after being boosted by the compressor unit 9, it can be transported to the fuel gas pipeline network 10; the other path of gas can pass through the liquid separation tank 2 to the water seal tank 3. When the pressure of the flare gas is greater than the water seal height of the water seal tank 3, the flare gas enters the ground flare 5 or elevated flare 4 for incineration;
[0030] Under normal working conditions, the flare gas is delivered to the fuel gas pipeline network 10 and the ground flare 5 and the overhead flare 4 are extinguished. Under normal working conditions, the self-control valve 7 provided at the outlet and inlet of the gas cabi...
