Embodiment Construction

[0027] figure 1 The illustrated device includes a vertically oriented closed cylindrical housing or housing 12 . It can be considered that the housing 12 is divided axially into an upper separation chamber 20 and a lower mixing chamber 40 by means of the partition 14 .

[0028] In the separation chamber 20 , a centrifugal separator 22 is mounted centrally, driven by an electric motor 25 located on top of the housing 12 . Centrifuge 22 has a lower central inlet 24 opening towards mixing chamber 40 and a radial or tangential outlet 26 protruding from housing 12 . The centrifugal separator 22 also has a rotor 28 comprising a stack of frusto-conical surface elements 30 .

[0029] Such as figure 1 As shown schematically in the enlarged area of ​​, the surface elements 30 are kept at a small distance d from each other by suitable spacing elements 32 , for example in the form of radial flanges formed on the surface elements 30 . As the centrifuge 22 operates, airborne particles a...

Abstract

Disclosed are a method and apparatus for cleaning an air flow from particles, such as bacteria and other microorganisms. According to the invention, an aerosol of liquid droplets is generated in the air flow, whereafter the liquid droplets and the air flow are mixed and the droplets and particles are centrifugally separated from the air flow.

Description

technical field [0001] The present invention relates to a method and apparatus for removing particles from an air stream. Background technique [0002] During surgery, for example, it is important to keep the air surrounding surgical wounds free of harmful particles such as infectious bacteria and other microorganisms. The air in an operating room is purified using effective filters, but it can still contain these harmful particles. Therefore, there is a need to provide cleaner air in medical and other usage areas. Contents of the invention [0003] The object of the present invention is to provide a method and a device capable of effectively removing airborne particles, especially microorganisms, especially bacteria. [0004] According to one aspect of the present invention, the method comprises the steps of: [0005] Generates an aerosol of droplets in the air stream, [0006] mix the aerosol and the air stream, [0007] centrifuges to separate droplets and particle...
