Principles of air filtration

Author: DEAR AST

In the process of air separation, raw air must be pretreated to produce qualified products such as oxygen, nitrogen and argon.

 

There is a lot of dust in the air. For the air turbine compressor in high-speed operation for a long time, the dust will cause wear, corrosion and scaling of the internal parts of the machine, and shorten the service life of the machine. Therefore, the raw air filter must be set.

 

Inertial impact: the smaller particles can pass through the micropores of the filter element, but the path through the filter medium is tortuous, and the particles have enough mass and momentum to collide with the filter element fiber and be blocked and trapped.

 

Brownian diffusion: very small particles with very small mass collide with the filter fiber during Brownian motion diffusion with the air flow and are filtered out.

 

Direct blocking: when the dust particles larger than 1 micron pass through the micropores of the filter media, they are directly blocked and blocked because the particle diameter is larger than the micropore diameter, so as to achieve the purpose of removing impurities.

 

Gravity sedimentation: the dust particles are constantly gathering until their mass becomes large enough. Under the action of gravity, they fall to the bottom of the filter or are discharged by the ash discharge valve.

With the development of social economy, the air separation plant becomes larger. The scale of air compressor, supercharger and other units of large air separation plant is increasing. Taking the air compressor as an example, power of the main motor has reached more than 30000 kw. For the different power grid conditions, motor configuration and motor starting mode of different users, the related electronic control design technology of air separation plant has been improved correspondingly. Here is a brief introduction to the starting mode of air compressor motor.
