Working principle
As shown in Figure 3, gas pipe line automatic gas-locking dewatering unit 23 and coal gas drainer 20 supporting uses are installed on the spill pipe 19 of coal gas drainer 20.
In coal gas drainer 20, be full of water, when flow-off 3 had water to overflow, the floating drum 8 in the gas pipe line automatic gas-locking dewatering unit 23 overcame the gravity of self under the effect of buoyancy of water, and drivening rod a10 moves upward together, and water level display pole 7 stretches out dust cover 5.Pivoted arm 12 is under the drive of connecting rod a10, and the arm axle ear 11 that rotates rotates, and makes the 15 down motions of lock gas plate through connecting rod b13, and the drainage channel on the demarcation strip 1 is opened like this, and condensed water up earlier through Storage water tank 4, is discharged by flow-off 3 thus again.
Drawdown in coal gas drainer 20, floating drum 8 also descends because of the effect of gravity thereupon, and through connecting rod a10, pivoted arm 12, connecting rod b13 drive the 15 up motions of lock gas plate, finally lock gas plate 15 and through seal ring 14 drainage channel on the demarcation strip 1 are closed.
If still greater than the working pressure of coal gas, then coal gas drainer 20 continues drainings to the water seal height of coal gas drainer 20 at this moment, this moment is through the 2 continuous air discharges with 1 of the water surface to demarcation strip of the Decompression valves on the demarcation strip 1; Along with the continuous discharge of condensed water, water level constantly rises, and the buoyancy that rises to floating drum 8 when water level is during greater than its weight; Floating drum 8 rises, and drivening rod mechanism descends lock gas plate 15; Original pent passage is opened again, can continue draining.
If the water level of coal gas drainer 20 is reduced to when being not enough to seal gas pressure; Leaking will appear in coal gas, and at this moment, the passage on the demarcation strip 1 is closed; The coal gas that leaks can only be discharged through Decompression valves 2; Because Decompression valves 2 is designed to be higher than the working pressure of coal gas, therefore, coal gas still is locked in the gas pipe line automatic gas-locking dewatering unit 23.
Because the drainage channel of gas pipe line automatic gas-locking dewatering unit 23 is closed; So when the condensed water of gas pipe line 22 constantly increases; The inner sealing water levels of coal gas drainer 20 constantly rise, when this sealing water level during greater than the design pressure of Decompression valves 2, and Decompression valves 2 instantaneous being opened; The coal gas that pin inside is discharged; Because the coal gas amount of this moment seldom, the coal gas between the water surface to demarcation strip 1 that was just leaked out originally, a large amount of coal gas still by the water seal shutoff in the coal gas drainer 20.So after this sub-fraction coal gas is discharged from, water level will rise again gradually, when water level rose to floating drum 8 and floats, lock gas plate 15 descended again gradually, and the passage on the demarcation strip 1 is progressively opened, and coal gas drainer 20 recovers proper functioning again.
When the superpressure situation appearred in gaspipe network, the water in the coal gas drainer 20 was gone out in a large number, and floating drum 8 is because of the lack of water loss of buoyance; Lean on the weight drivening rod 10 of himself to descend; Through linkage mechanism lock gas plate 14 is risen, cover the passage on the demarcation strip 1, a large amount of coal gas are locked in the device.When condensation water quantity was increased to the pressure that overcomes Decompression valves 2 in the coal gas drainer 20, the coal gas that original leakage that this part water surface to demarcation strip is 1 is come out was progressively emitted from Decompression valves 2 again, and a large amount of coal gas is being sealed by water seal in the coal gas drainer 20 again.After water level in installing rose to floating drum 8 is floated, through the drive of linkage mechanism, lock gas plate 15 was opened the drainage channel on the demarcation strip 1 again, and coal gas drainer 20 recovers normal draining again.
When big water quantity appearred in gaspipe network, because the shunting action of guiding flow distribution plate 16, a large amount of current did not directly impact lock gas plate 15, so the drainage channel on the demarcation strip 1 can not be closed, have solved the continuous drainage problem of this device under the big water quantity operating mode.
