Un-treated gas enters tangentially through the inlet at the side of the separator. The gradually narrowing conical section is known as the cone. The main cylindrical part of the cyclone separator is known as the body or barrel. Components and DesignĪ reverse flow cyclone separator is an industrial assembly with no moving parts and a simple design. This measurement is an industry standard measurement and can usually be obtained from the original equipment manufacturer (OEM). The cut point is the point at which particles are removed from the gas stream at 50% efficiency. The volumetric flow rate and geometry of the cyclone separator define the cut point. Because particles have different sizes, the efficiency rating is usually given for varying particle sizes. The collection efficiency -also known as the capture or recovery rate- is a measurement of a cyclone’s ability to separate particles from the flowing gas stream. We will refer to the term collection efficiency, or simply ‘ efficiency’ throughout the article. This article will focus on the reverse flow gas cyclone separator because this type of separator is the most common in use today. Axial flow separators are not as common as reverse flow separators. straight through) cyclone separators, gas enters at one end and is discharged at the opposite end. Reverse Flow Cyclone Separator With Swirl Generatorįor axial flow (a.k.a. Below is another variation of the reverse flow cyclone. Various reverse flow cyclone separator designs exist. Gas enters the top of the separator body, flows downwards, then flows back upwards and is discharged. Reverse flow cyclone separators are cone shaped. Gas cyclone separators are grouped into two main categories, reverse-flow and axial-flow. Separators can be installed with a horizontal or vertical orientation. It is also possible to install cyclones in series, or, in parallel. Hydrocyclones are used for separating fluids of different densities.Ĭyclone separators can be installed as single units, or in multiples, known as multi-cyclones. Gas cyclones are used to remove entrained particles from a gas stream. There are two main designs of cyclone separator, these are the gas cyclone and hydrocyclone. Generally, smaller units are referred to as ‘dust’ separators or extractors, whilst large scale industrial separators are referred to as ‘cyclone separators’. These names include ‘ dust separator’, ‘ dust collector’, ‘ dust extractor’, ‘ cyclone extractor’ and ‘ cyclone separator’. This article focuses on the gas cyclone separator.Ī cyclone separator has several colloquial names. Cyclone separators often form part of a pre-cleaning stage prior to a gas or liquid being discharged. Cyclonic separation is a means of separating different liquid phases (different liquid densities), or, separating particles from a gas stream.
