TECHNOLOGICAL EVALUATION OF THE SEPARATOR OF FLUME AND WASH WATER

The paper deals with evaluation of the operation of a prototype of sep arator of flume and wash water. The device was developed and manufactu red in the works of ZVU Hradec Kralove. It was put into the testing op eration in the 1989 sugar campaign in the Sugar Factory Doksany. This report follows the previous article by M. Hubka (1) published in Listy cukrovarnicke (1990) describing the tested device. The investigations were concentrated before all in efficiency of sand separation. A sign ificant attention was payed to granulometric analyses, composition of sediments and the influence of quality parameters or dispersed particl es on the resulting separation effect. The separator has been working during all the measuring period without any, at a minimum need of staf f or check. The separation efficiency at the sand content 82% for the fraction 0,2 - 0,4 mm had been reached with water inlet to the separat or in the range 8 - 13,5 m3/min with an average sediment content 1,26 vol.%. This proves the guaranteed values. A high separation efficiency (69%) had been measured also for finer fractions with grain size 0,1 - 0,2 mm.
