Abstract

The utility model belongs to natural gas separating mechanism, which is a rectifier type folded plate during crossing of an air inlet pipe and a barrel, comprising a round tubular folded plate casing welded with an eddy plate. One end of the folded plate casing is welded with the inner wall of a separator barrel, the other end is sealed by an end plate, and a rectangular orifice is opened on circumference of the folded plate casing. Air current collides with the end plate, rotates 90 degrees, and enters the barrel from the eddy plate and the rectangular orifice along tangent direction. The air current shunted from the hole on circumference of a cyclone discharge pipe is discharged from an isocon and a large head of an isocon burner cap, with a direction opposite to rotating direction of air current passing the rectifier type folded plate, which increases air current collision probability.

Description

The large-scale gas-liquid separator of band rectifier type flap

The utility model relates to a kind of large-scale separator air flow inlet version, is mainly used in natural gas purification, separation equipment.

At present, separator generally adopts the tangent line inlet, in order to improve separative efficiency.On cylindrical shell, open an elliptical aperture more much bigger, not only increased manufacture difficulty and cycle, and cause the stress of container to worsen than air inlet pipe diameter.

The purpose of this utility model is to avoid opening on large-scale separator bigger elliptical aperture, adopts air inlet pipe and separator cylindrical shell quadrature.But this moment, the air-flow that enters cylindrical shell just is not along the air-flow of cylinder inboard wall rotation.Adopt the utility model, promptly the rectifier type flap when air inlet pipe and cylindrical shell quadrature, still can make air-flow enter cylindrical shell along tangential direction, has both avoided opening bigger elliptical aperture, can utilize the liquid particle in the centrifugal force method separation bubble again.

The purpose of this utility model is achieved in that at the separator air inlet rectifier type flap is set, and is made up of flap shell, gripper shoe, cowling panel, horizontal cowling panel, end plate, stud and reinforcing ring.In tubular flap shell, be welded with cowling panel, the welding of flap shell one end and separator cylindrical shell inwall, the other end is by end plate closes, on flap shell circumference, horizontal cowling panel one side opens rectangular opening.The width of the rectangular opening of opening should be in the cowling panel integer, and radian is with flap shell center goniometer.Guarantee on the flap shell rectangular opening edge not unsettled, with the cowling panel welding, can avoid producing vibration.The former is the cowling panel number to the maximum and subtracts 1.The latter is 30 °～180 °.From Fig. 1 and Fig. 2, can see: air-flow that enters by inlet connection and end plate collision, change 90 ° after, tangentially enter cylindrical shell from cowling panel, rectangular opening.

In order to improve separative efficiency and to reduce the liquid particle size and the quantity of discharging in the air-flow, getting out diameter on the cyclone type blast pipe circumference in diffluence room is that d, pitch-row are the N round of 2d, and distance is t between every round.The air-flow that distributes thus is through isocon, from the ejection of the isocon shower nozzle that has a down dip.The isocon shower nozzle is made up of 90 ° of elbows and a concentric reducer, and its microcephaly is identical with elbow diameter and weld together, and shower nozzle has enough settlement spaces.Air-flow is through the major part ejection of the concentric reducer of isocon shower nozzle, and its direction is with opposite through the air-flow direction of rotation of rectifier type flap outlet.

Owing to adopt said structure, can avoid container to open elliptical aperture, increase the airflow collision probability, improve separation accuracy and efficient.

Below in conjunction with accompanying drawing and example the utility model is further specified.

Fig. 1 is the gas-liquid separator structure chart.

Fig. 2 is a rectifier type flap detail drawing.

1. discharge connections among the figure; 2-0. rectifier type flap; 3. inlet connection; 4. baffle plate; 5. cylindrical shell; 6. aluminium floating plate; 7. aluminium is prevented rotating plate; 8. blow-off pipe; 9. skirt; 10. isocon shower nozzle; 11. diffluence room; 12. cyclone type blast pipe; 2-1. flap shell; 2-2. gripper shoe; 2-3. cowling panel; 2-4. horizontal cowling panel; 2-5. end plate; 2-6. stud; 2-7. reinforcing ring.

In Fig. 1, the gas that contains liquid is entered by inlet connection (3), changes 90 ° through rectifier type flap (2-0), along the circumferential direction flows out, and enters expansion chamber (C) from baffle plate (4) downwards through air-flow vortex chamber (B) rotation.Gas rotates up mobile at cyclone type blast pipe (12), the gas that a part flows enters discharge connection (1) and discharges; The gas that another part flows, hole enters diffluence room (A) on wall, enters isocon (11) then, discharges from isocon shower nozzle (10).

In Fig. 2, the gas that contains liquid enters rectifier type flap (2-0) afterwards, and with end plate (2-5) collision, and the 90 ° of rectangular openings opened from flap shell (2-1) through horizontal cowling panel (2-4) of turning back flow out.
