separadores de impactor gás-liquido inercial e método para expandir dado intervalo de faixa de banda estreita a faixa de banda mais ampla e para deslocar a faixa para deslocar o tamanho de cut-off para incluir diâmetros de partículas menores

摘要

An inertial gas-liquid impactor separator includes an inertial impactor collector having an impactor surface extending diagonally relative to axially accelerated flow, which surface is preferably a cone having a leading tip axially facing and axially aligned with the acceleration nozzle. In a further aspect, first and second inertial impactor collectors are provided in series, with an orifice in the first inertial impactor collector providing a nozzle for the second inertial impactor collector. Improved performance is provided by reducing the extent of the stagnation region to change from a narrow band particle size range to a wider band range and to shift cut-off size. An inertial gas-liquid impactor separator has a perforated layer of coalescence media having at least one aperture through which the gas-liquid stream flows. Improved performance is provided by increased penetration of the flow into the media patch and thereby enhancing particle capture by interception, impaction and diffusion.
