TLDR
Particle collection efficiency and gas pressure drop for venturi and other atomizing scrubbers can be predicted by means of equations developed in this paper, where the significance of the details of the liquid atomization process, the collection of particles on single drops, and the uncertainty regarding them are discussed.Abstract:
Particle collection efficiency and gas pressure drop for venturi and other atomizing scrubbers can be predicted by means of equations developed in this paper. The significance of the details of the liquid atomization process, the collection of particles on single drops, and the uncertainty regarding them are discussed. The role of drop holdup in the scrubber throat is also important.read more

Dust particle removal efficiency of a venturi scrubber
TL;DR: In this article, the authors focused on the dust particle removal efficiency of the venturi scrubber experimentally and theoretically and employed a mathematical model for the verification of experimental results and showed that the removal efficiency is higher with the increase of throat gas velocity and liquid flow rate.

Drop size measurements in Venturi scrubbers
TL;DR: In this paper, drop sizes in a cylindrical laboratory-scale venturi scrubber were measured using a laser diffraction technique, and the results showed that the Sauter mean diameter of the spray can be well correlated by the equation of Boll et al. (J. Air Pollut. Control Assoc. 24 (1974) 932).
