Description

one

The centrifugal separating device relates to gas field equipment and is intended for cleaning natural gas from dropping liquid and mechanical impurities, and can also be used in all sectors of the industry related to the purification of gas streams.

A centrifugal separating device is known, comprising a housing, an inlet, equipped with swirl blades mounted between the rings, and a regulating element.

The known device has a low cleaning efficiency and high hydraulic resistance.

In order to eliminate this drawback, the regulating element is made in the form of a movable disk with slots having the form of swirl blades that enter the slots. It is installed between the rings and supplied with a rod with a lifting device.

FIG. 1 shows a centrifugal separator in section; in fig. 2 is a section along A-A in FIG. I.

The centrifugal separating device contains rings I, 2, between which the swirl blades 3 are rigidly fixed tangentially to the hole (for example, by welding). Between the rings 1, 2 there is

movable disk 4 with slots 5 made in the form of vortex blades.

With the movable disk 4 is rigidly connected to the rod 6 of the lifting device 7, made in the form of a screw pair and mounted on the rack 8 U-shaped. The rack 8 is attached to the IK body of the apparatus, which is shown in a conventional manner.

Transition pipe 9 forms together with

a gas outlet 10 and a tray // bath 12 for collecting the separated liquid, for discharging which a pipe 13 is provided, which is rigidly attached to the tray 11. Inside the gas outlet 10, at its edge there is a swirler 14.

The device works as follows. The purified gas enters the device as indicated by the arrow. The passage is a gap formed by the adjacent swirl blades

3, the gas acquires a calculated inlet speed corresponding to the highest separation efficiency and moves along a circular path relative to the axis of the device. Under the action of centrifugal forces resulting from the rotation of the gas flow, the liquid droplets are thrown to the peripheral rotational zone, transferred to the inner surface of the transition nozzle 9 and then fall into the bath 12 to collect the liquid, from where they are diverted through the drainage pipe 13 from the device. The cleaned rotating gas stream enters the gas outlet nozzle 10, where, falling into the swirler 14, it spans, i.e., the rotational movement turns into translational.

Depending on the amount of gas entering the centrifugal separation device for cleaning, a definite distance is established, between the movable disk 4 and the ring 2. The movement of the disk 4 is carried out by means of a lifting device 7 and a choke 6. Thus, the calculated gas entry rate into the device corresponding to the greatest separation efficiency under the given conditions.
