Because the separated natural gas contains petroleum oil foam and needs foam breaking treatment, the natural gas above is gathered from two ends to the center, the natural gas with petroleum oil foam passes through the first foam breaking net 112 and is broken for the first time, the petroleum oil foam in the natural gas is attached to the first foam breaking net 112 to form oil beads, the petroleum oil foam falls into the petroleum below freely by gravity, the natural gas after the first foam breaking treatment continues to gather to the center of the buffer tank 102, then the natural gas is split to two sides by the split flow block 301, part of the natural gas is simultaneously offset with the natural gas split to two sides by the baffle holes 304, part of the natural gas is impacted to the first foam breaking net 112 again to break foam, the content of the oil foam in the natural gas is reduced again, after the natural gas at two sides moves to the center along the split flow block 301 to generate collision impact, the natural gas starts to diffuse rapidly at the moment, the natural gas is diffused to the first foam breaking net 112 and the second foam breaking net 302 to be subjected to foam removal treatment again, when the natural gas passes through the second foam breaking net 302 and then enters the cavity formed by the spiral guide plate 303, the flow dividing block 301 and the second foam breaking net 302, the mist catcher 110 performs negative pressure extraction on the natural gas, as the cavity formed by the spiral guide plate 303, the flow dividing block 301 and the second foam breaking net 302 is of a spiral structure, when the extraction is performed, the natural gas rises, the oil foam is centrifugally flung to the inner wall of the flow dividing block 301 and the inner wall of the second foam breaking net 302 again when the natural gas rises, and then flows into the lower oil by gravity, at the moment, the lower oil level drives the sliding plate 402 to slide along the baffle 401 through the float 404, the baffle 401 shields the upper second foam breaking net 302, so that the natural gas enters the cavity formed by the spiral guide plate 303, the flow dividing block 301 and the second foam breaking net 302 through the gap between the baffle 401 and the sliding plate 402, the natural gas is ensured to enter the cavity from the lower part to participate in centrifugal defoaming, the upper natural gas is prevented from being directly extracted by the negative pressure of the mist catcher 110, and the defoaming effect of the natural gas is reduced.
The two servo motors 501 are in an on state, the servo motors 501 drive the reciprocating screw rods 503 to rotate through the gear boxes 502, the reciprocating screw rods 503 drive the pushing blocks 504 to reciprocate, the pushing blocks 504 drive the scrapers 505 to scrape down the petroleum precipitants below, excessive precipitation of impurities in petroleum is prevented, the liquid level meter 108 is inconsistent with the actual liquid level, workers do wrong operation, when the scrapers 505 scrape the impurities on the inner wall of the buffer tank 102, the scraped impurities are guided to the bottom of the buffer tank 102 by the scrapers 505, after the impurities are contacted with the guide blocks 507 in the downward movement process of the impurities, the guide blocks 507 drive the impurities to be guided into the adjacent flow grooves 506, the impurities are evenly mixed in flowing petroleum and are discharged along with the petroleum through the oil outlet pipeline 107, so that excessive precipitation of the impurities to the bottom of the buffer tank 102 is avoided, when the pressure gauge 109 detects that the internal pressure of the buffer tank 102 changes, workers correct the pressure in the buffer tank 102 through the safety valve 111, and the pressure fluctuation is avoided to influence on petroleum and gas transportation.
