DIRECT CUTTER SEPARATOR

(54)

The invention relates to devices used for the separation of mixed streams and, in particular, is the separation of a heavier phase (liquid, mechanical impurities, etc.) from a heterogeneous gas stream, and can be applied in the petrochemical chemical, oil and gas industry and other industries. x national households.

A linear separator is known, comprising a housing, a centrifugal flow separation unit, an inlet and an outlet 1. In a known separator, due to centrifugal force, the phases are separated, and the convection phase is separated from the wall of the separator housing.

Also known is a straight separator, comprising a housing, split with a hollow, a transverse partition, provided with a fairing, inlet and outlet nozzles 2.

The disadvantages of the known straight-through separator are the impossibility of changing the radius of curvature of the vortex without changing the flow rate, which reduces the separation efficiency and the increased length of the deposition phase of the heavy phase from the center to the chamber wall; intensive axial spin flow, which impairs the process

separation and creates additional hydroresistance.

In order to increase the separation depth and reduce vortex formation and hydraulic losses, in the previous straight separator, the transverse partition is made with a ridge protrusion located in the cavity of the casing and smoothly aligned with the fairings, which are shaped by concentric shaped pipes.

At the same time, on the outside of the housing, an annular chamber for removing a heavy phase is installed, which connects the cavity of the housing and the outlet. It is advisable to perform a transverse partition and fairing hollow, and the fairing in the area of the outlet with a hole.

The drawing shows the proposed separator, a longitudinal section.

It includes a housing 1, an inlet 2 and an outlet 3 nozzles, a centrifugal separation unit having a transverse partition 4. It is made with a toroidal protrusion 5, and the body wall at the location of the transverse partition is made in the form of a toroidal cavity 6 with a gap.

for example, a variable cross section forming an annular separation chamber 7.

The transverse partition is made on both sides of the inlet 8 and the outlet 9 fairings made of profiled and mated with a toroidal protrusion 5. Concentric fairings have guide tubes 10 for aligning the flow at the entrance to the annular chamber 7 and guide tubes 11 for welding flow pa exit from this camera. To provide the required clearance, which forms an annular chamber and gaps between the inlet fairing 8 and pipes 10, the outgoing fairing 9 and pipes 11, the transverse partition and guide pipes are installed on pylons 12 and 13. To ensure an effective trunk of a heavy phase between the housing and the outlet A nozzle 3 is provided with an annular chamber 14, covering the outlet nozzle, executed, for example, in the form of a truncated cone and having an annular intake opening a for diverting a heavy phase from the separation zone and a nozzle for drainage phase in the team capacity. The transverse bulkhead and fairings are hollowed out, and for unloading from excessive external pressure, the fairing 9 has an opening 5 in the area of the outlet nozzle.

The proposed continuous separator operates as follows.

The heterogeneous stream enters the inlet 2, turns to the periphery along the flap 8 and the guide tubes 10, accelerates between toroid-shaped surfaces in the annular chamber 7. Under the action of centrifugal forces, a yellow phase precipitates in the annular chamber, which is discharged through the annular an intake opening into chamber 14. Further, the t phase is drained through pipe 15.0 and the stream from the annular chamber 7 enters the channels between the outlet fairing 9, guide pipes 11 and pipe 3 and sweat parallel someone leaves the separator.

At the beginning of the operation of the separator, a part of the flow through the opening 5 penetrates into the Polish node of the centrifugal separation of the flow and it is unloaded from the excess superfluous pressure. The implementation of this device with a toroidal slit allows you to simultaneously provide the necessary speed and radius of swirl flow, regardless of the diameter of the separator and, thus, to achieve high separation efficiency.
