Description

one

WG acquisition relates to flow centrifugal separators for separating liquid droplets from a gas stream and can be widely used in tenlomassoobmennyh devices in the chemical, gas, oil and other industries, as well as in wet gas cleaning processes.

A centrifugal separator is known, consisting of separating nozzles, in the lower part of which a swirling device is located, and in the upper part - a separator of the separated liquid, which is elongated in the form of a cap 1.

Also known is a centrifugal separator containing a cylindrical separating chamber with grooves located on its periphery for collecting fluid and an axial swirler 2.

A disadvantage of the known constructions is a narrow range of effective work, but the content of the liquid phase in the gas stream, since the removal of liquid without secondary entrainment is provided only at a certain optimum content of liquid in the gas.

The purpose of the invention is to increase the efficiency of separation 1 with variable modes.

This is achieved by the fact that the grooves of the separator chamber are made in the inner ring corrugations of the C-holes in their lower part. FIG. 1 shows the proposed separator, a longitudinal section; in fig. 2 - knot

I drain the filtered liquid of FIG. one.

The separator contains a vertical separating chamber 1 with installed

the lower part of the multi-blade swirls 2. The chamber 1 is rigidly attached to the web of the tray 3. In the upper part of the chamber 1 several rows of corrugations 4 with holes 5 are made. The holes are located in the lower half of the corrugations and directed at an acute angle

to the forming surface separaununnop camera. In the plate there is a discharge pipe, G separated liquid.

The proposed centrifugal senator works as follows.

The gas stream containing droplets on the inlet chamber 1, pro- swath swirl 2. acquires a vran1, movement movement. Under the action of centrifugal forces, the liquid is thrown onto the inner wall of the separating chamber and the dilsets in the form of a film upwards. When it gets into the corrugations 4, the liquid in them accumulates and is squeezed out by centrifugal force through the openings 5. The purified gas stream rises upwards. Separated liquid through the discharge pipe (i

can be removed from the system or fed back into the machine.

The proposed unit for drainage of the separated liquid is calculated on the maximum possible presence of gas in the gas stream, i.e. the removal of a film of liquid is carried out through the openings of all the corrugations. When the liquid content in the gas flow decreases, the first series of corrugations (where only the liquid goes out through the openings) are removed, and the last rows are released by gas. The location of the nodes with an acute angle to the generatrix generators of the orifice excludes the collision of the jets of adjacent pipes, which improves the conditional senorization.

Comprehensively conducted studies of the developed centrifugal senator showed its steady operation in a wide range of load variations but fluid

and higher efficiency than similar designs.
