Abstract
PURPOSE: To improve thermal efficiency, by continuously freezing, liquidizing and dehydrating sludge by winding a conveyor belt and travelling filter cloth between a cooling drum for freezing sludge and a heating drum for liquidizing it and by contacting sludge with each drum surface by holding sludge between both drums.
CONSTITUTION: Sludge is freezing treated by placing it on travelling filter cloth 20 from a sludge feed means 18, by holding it by means of a conveyor belt 19 and by turning it while contacting it with a cooling drum 16. The sludge is liquidation treated by rotating it while contacting it with a heating drum 17. The sludge is dehydration treated by means of a dehydration means 21. And dehydrated cake is scraped off by means of a scraper 25, and carried out by means of a conveyor 26.
