Abstract

PURPOSE: To shorten time necessary for solidifying solid matter, by heightening an evaporating effect of moisture in slurry-like matter by adding chaff, etc. to the slurry-like matter and by heating the matter.
CONSTITUTION: Slurry discharged from working factories is charged into a mixing tank 2. Chaff powder a is charged into the mixing tank 2 by means of a measuring screw 6 from a bottom of a storage tank 5 in appropriate quantity corresponding to the quantity of slurry and the concentration of slurry. Slurry and chaff powder mixed, introduced to an evaporator 9 by means of a screw 9 from a bottom of the tank and heated being agitated. Moisture in mixed liquid is changed into steam c, and solid matter is extracted as matter d to be disposed and recovered as fertilizer, etc. Since the viscosity of slurry increases by the mixing of the chaff and the efficiency of heat-transfer is heightened, the efficiency of the evaporation of moisture is promoted, and running cost for disposing drainage is reduced.
