“…The split of liquid between the film and drops depends on the gas velocity, liquid flow rate, and especially on the liquid injection system. Behie and Beeckmans (1974) and Rudnick et al (1986) have pointed out that the liquid injection system and geometry have a strong influence on the performance of Venturi scrubbers. This is due to the effects of the hydrodynamics, which results in different pressure drops and, therefore, in removal of dust and chemical pollutants.…”

Liquid distribution along an ejector-Venturi scrubber was determined experimentally in an industrial-scale pilot plant. The effects of geometry as well as flow rates were studied. The results showed that a significant fraction of the liquid travels as a film. Therefore, it should be taken into consideration in mass transfer studies, where usually it is neglected. The data were used to test a model, that allows for interchange of liquid between drops and film flowing on the Venturi walls. There was good agreement between experiment and predictions.

“…In order to comply with these constraints, it is necessary to develop new technologies as well as to improve those already existing. The Venturi scrubber is a wet technique that is used for the removal of gaseous pollutants, and can achieve efficiencies of 97% for particles down to 1µm in diameter [3,2]. As a consequence, these devices have been the subject of numerous studies, particularly in recent years.…”

The Venturi scrubbers have a high collection efficiency to remove very small particles from gaseous streams. The main purpose of this work is to determine the overall collection efficiency of Venturi scrubbers with circular section under different operation conditions. The experimental system consisted of a Venturi scrubber with circular section and liquid injection in the throat. A factorial experimental design was carried out; the overall collection efficiency was the response. Three variables were analyzed: the throat length, the air velocity and the liquid flow. The best values for efficiency were obtained for 15 m/s of air velocity and 300 mL/min of liquid flow and the throat length did not have influence.

“…It is common for these industries to generate large quantities of submicron sticky particles which block a filter and make the utilization of baghouses almost impossible (Whitcombe [2]). On the other hand, wet scrubbers in most cases cannot provide required efficiency levels (Agranovski et al [1], Calvert [3], Behie et al [4]).…”

Chemical and metallurgical industries frequently generate submicron wet/dry sticky particles. Conventional wet scrubbers, usually Venturi scrubbers, are used in such industries with varying degrees of success. These scrubbers may be capable of removing larger particles, but become inefficient when particle size drops below the one‐micron level. The main idea of this project was to utilize a wettable filtration system after the scrubber to achieve a high removal efficiency with a relatively low increase in total pressure drop. The use of wettable filtration allows an equilibrium liquid film to develop on each of the filter fibres (Agranovski et al. [1]). This liquid film than acts as the primary filtration zone, removing particles before they reach the filter's surface. The filtered contaminants are then removed from the fibre by a continuous influx of fresh water preventing blockages to the system. The new filtration systems can be incorporated into existing air pollution control systems by utilizing a space inside hollow liquid/air separators commonly used for the baffling of droplets after wet scrubbers. The new wettable filtration system installed at a strip galvanizing plant achieved removal efficiencies of approximately 98.6 % for the total particle loading with a minimal increase in pressure drop.
