TL;DR: In this paper, the overall particle collection efficiencies of spray scrubbers using monodisperse droplets of 100,500, and 1000 microns diameter were calculated for the cases of evaporating and condensing droplets.
Abstract: The overall particle collection efficiencies of spray scrubbers using monodisperse droplets of 100,500, and 1000 microns diameter were calculated for the cases of evaporating and condensing droplets. The properties of the gas at the inlet to the spray scrubber were maintained constant at 150°F, 100% relative humidity, and 1 atmosphere pressure. At the liquid entrance to the spray scrubber, the water droplet temperature was 50° F for the condensing case and 180° F for the evaporating case. The liquid to gas flow rate ratio for all the calculations was held constant at 4 gal/1000 acf. The gas velocity in the co-current spray tower was 1 ft/sec in the downwind direction. The calculation results show that for the particles in the 0.01 to 10 Mm diameter range, the overall spray scrubber particle collection efficiency is greater with the cooler 50°F water (condensing case) than with the warmer 180°F water (evaporating case). The effect of diffusiophoresis and thermophoresis is noticeable for all the water dropl...

27 May 1977TL;DR: In this paper, a spray tower is used for cleaning waste flue gas, where a reactant solution is sprayed into a waste gas, and the water contained in the droplets is vaporized and the reaction products are dried into solid particles by the sensible heat of said flue gases.
Abstract: A waste flue gas cleaning method and an apparatus for practicing said method, in which a reactant solution is sprayed into a waste flue gas introduced into a spray tower, whereby a toxic component in the flue gas is caused to be absorbed in and react with the droplets of the sprayed reactant solution, and the water contained in the droplets is vaporized and the reaction products are dried into solid particles by the sensible heat of said flue gas. A series of the above operation is accomplished within the spray tower while maintaining the outlet gas temperature always above the dew point of the flue gas, and the solid particles of the reaction products are removed from the flue gas by an after dust collector.

TL;DR: In this paper, the authors describe a corrosion testing machine having a cell within which specimens are to be subjected to corrosion testing; a spraying tower in the center of the cell and having means therein for producing a spray of a testing liquid extending in all directions from the top of the tower; a supporting column within the cell, rotatably mounted for rotation around the spraying tower; and an annular frame mounted on the supporting column around the spray tower having supports for supporting test pieces thereof in an inwardly and downwardly inclined position with the surfaces to be tested facing inwardly or upward
Abstract: A corrosion testing machine having a cell within which specimens are to be subjected to corrosion testing; a spraying tower in the center of the cell and having means therein for producing a spray of a testing liquid extending in all directions from the top of the tower; a supporting column within the cell and rotatably mounted for rotation around the spraying tower; a motor coupled to the supporting column for rotating the column around the spraying tower; and an annular frame mounted on the supporting column around the spray tower having supports for supporting test pieces thereof in an inwardly and downwardly inclined position with the surfaces to be tested facing inwardly and upwardly toward the top of the spray tower. In the machine the spray of the testing liquid is evenly applied to the surface of the specimens to be tested.

TL;DR: In this article, hot gases containing naphthalene and tar together with the possible inclusion of solids are contacted in a spray tower with water to cool the gases, and then the admixture is separated in a settling tank from which water is obtained and recycled to the spray tower for cooling further quantities of gases.
Abstract: Hot gases containing naphthalene and tar together with the possible inclusion of solids are contacted in a spray tower with water to cool the gases. A naphthalene extraction agent, such as tar, is vigorously admixed with water withdrawn from the spray tower. The admixture is separated in a settling tank from which water is obtained and recycled to the spray tower for cooling further quantities of gases. Solids, gas condensate and tar enriched with naphthalene are separately removed from the settling tank.
