731,014. Purifying liquids; gravity-separation apparatus. NITROGLYCERIN AKTIEBOLAGET. April 28, 1953 [April 29, 1952], No. 11664/53. Class 46. The apparatus shown is for washing a liquid such as a nitrated product with another liquid immiscible with it and having a different specific gravity. Washing liquid, such as water, to which an alkali has been added, introduced at 5, and nitroglycerine introduced at 4 are mixed in an injector 3 with the help of compressed air introduced at 6. The mixture passes into a chamber 1 where the air maintains vigorous movement before discharge at 9. The liquid mixture passes between plates 7 forming an angle of between 45 degrees and 60 degrees with the horizontal and spaced apart by a distance small (e.g. 5 mm.) compared with their extent into an intermediate compartment 8 and thence through openings 12 in a wall 10 into a separating chamber 11. From the latter the washing liquid overflows at 16 and the nitroglycerine at 15. The lower end of the separating chamber 11 communicates with an inspection glass 13 ; a layer h e of mixed liquids separating the two liquids may be maintained at the level of this glass by adjusting the height H between the overflow levels 15 and 16, for example with interchangeable nozzles.
