Abstract
PURPOSE: To produce brown coal of reduced moisture content, by supplying a brown coal slurry to a filter zone and continuously scraping a solid (brown coal mud) on the top of the filter zone.
CONSTITUTION: Filter zone 1 is formed by providing an annular space between outer periphery 2 and inner periphery 3 of a hollow cylinder, with filter mesh 4 inside, with water drain on the bottom and with vacuum suction pipe 8 below the filter mesh. Above said filter zone, a vacuum filter is formed by providing slurry supply conduit 6 revolving along the filter zone 1 and brown coal mud scraper 7 (height L from the filter mesh 4 to the top of the filter zone is such that water in the mud can rise by capillary phenomenon, or higher). A slurry obtd. by crushing brown coal of moisture content 40W70wt% into a particle of size 0.05W2mm and adding water, is supplied via feed conduit 6 to the filter zone 1, where it is separated into a solid and a liquid. At the same time, a solid on the top of the filter zone 1 is scraped into tank 10, to obtain a brown coal of moisture content ≤10%.
