Liquid Film Smoke Scrubber - A Feasibility Study.
Abstract
A liquid film smoke scrubbing concept is described. The feasibility of this concept was studied experimentally using the high expansion foam generators on hand to produce the liquid films and JP-4 fuel fires to produce the smoke. The experiments were conducted in a 5ft x 7ft fire test wind tunnel. Test results show that the scrubbing action took place mostly at the bubble films which substantiates the validity of the basic concept. Due to the limitations of the present experimental setup, only about 50% scrubbing efficiency could be obtained and the system suffered from excessive foam accumulations. Based on analyses and test results, it was concluded that these deficiencies can be greatly improved after the following developments are made: (1) A method for producing small size foam bubbles with high expansion ratios; (2) A smoke resistant and fast draining high expansion foam concentrate formulation. Because of the simple construction and the extraordinary large surface contact obtainable, this method is potentially economical and effective in pollution control. (Author)
