Collection efficiency and pressure drop were measured over a range of air flows at ambient tempera- ture and pressure. An oil mist was used as a test aerosol because it consisted of spherical drops of uniform density unlikely to bounce or reentrain after striking the cyclone wall. At each air flow, a fractional efficiency curve (col- lection efficiency versus particle diameter) was de ...
Get Price17.03.2016· The pressure drop and the residence time are the two key factors causing the desorption of dissolved gas. As a certain separation efficiency of dissolved gas has been achieved by the inner cone hydrocyclone through a small pressure drop, a degassing hydrocyclone will be developed to obtain a higher separation efficiency for dissolved gas. Later ...

Get PriceTo enhance the efficiency of hydrocyclone, it is very essential to quantify the presence or absence of air core within the hydrocyclone. In the present study, for the first time, a new hydrocyclone design has been conceptualized and tested for its efficiency in separation of particles based on gravity. Experimental investigations have been carried out using design of experiments and the ...

Get Price01.06.2020· A well-developed hydrocyclone should have high separation efficiency and ensured to work under lower pressure. The separation efficiency versus pressure drop ratio at two different temperatures at a mean droplet size of 37 µm are presented in Fig. 12, Fig. 13. The linear increase in the pressure drop with flow rate also depicts that efficiency ...

Get PriceIn the initial stages, the concentration is more and the pressure drop is more, therefore the separation efficiency is increased for some elapsed time. But later, the influent concentration decreases and the separation of finer particles will be difficult, so the separation efficiency decreases.
