Filed: 1925-04-08
Abstract: 254,797. Peddie, J. T., Lumsden, W. G. G, P., and Pirbright Co., Ltd. April 8, 1925. Purifying l i q u i d s; separating by gravity.- In a system for separating liquids of different gravity means are provided in a closed chamber and unexposed to the air for causing particles of negligible flotation power to coalesce for subsequent gravity separation. Animal hair, feathers, or horn shavings are suitable for this purpose. A mat of cow hair felted into a coarse jute textile as described in Specification 243,107 may be used. The coalescing means may be interposed in apparatus for separating. oil and water of the kind described in Specification 218,462. Fig. 3 illustrates one way in which this may be done. The mixed liquids enter an elongated chamber 1 provided with vertical baffles 7. The greater part of the oil separates and is collected in a compartment 3. The water containing some oil in very small particles is passed through a vessel 5 containing material, which will cause the oil to coalesce into drops, and thence to an upper settling compartment 6 where final separation takes place, the collected oil passing into the compartment 3 through an aperture 10. The material in the vessel 5 will initially act as a filter retaining the oil but when it has absorbed its maximum of oil, further oil will be cause to coalesce but not retained. Fig. 4 shows coalescing-apparatus comprising a number of pads 15 of cow-hair arranged between division plates 14<a> and providing alternative paths for the liquid. Specifications 15340/00, [Class 123, Steam generators], and 126,447 are referred to in connection with this form and apparatus.
