Advantages of rotary separators for gas pipelines

During the operation of the gas, dust and liquid particles may settle in the pipelines. They negatively affect both the pipeline fittings and the devices connected to the network. Rotary separators are used to purify the gas flow.

Why cleaning elements are needed

Poorly purified gas leads to the formation of explosive and toxic mixtures in pipelines, which can lead to the destruction of pipes, damage to equipment and emissions into the environment. Contamination negatively affects control and measuring devices, pressure regulators and safety elements, for example, shut-off valves.

The accumulation of condensate leads to freezing of the pressure regulators. Other elements of pipeline fittings are also subject to destruction, which leads to the suspension of production and to losses.

Advantages of rotary separators

The filter elements are designed to clean the gas stream from inclusions. Fixed-type filters are not suitable because they have disadvantages:

Mechanical filters are also unable to provide the required degree of purification due to insufficient filtration fineness and instability of operation during changes in gas flow pressure.
Rotary separators are devoid of these disadvantages. Their advantages:

Design and principle of operation

The separator consists of a rotor and a nozzle made of metal mesh and highly porous materials. The rotor rotates due to the movement of the gas flow or electric drive.

The gas passes through the nozzle, which, rotating, throws off droplets and dust particles by centrifugal force. These inclusions fall on the walls of the device and are removed through the lower fitting. Centrifugal acceleration reaches 3000 m/s2.

Such rotors are used in continuous production, for example, in thermal power plants.
