Abstract

PURPOSE: A drying treatment system provided with a detector which detects both of the washing effect in the washing process of an evaporating dryer and the drying effect in the drying process in combination.
CONSTITUTION: The waste liquid in a waste liquid tank 1 is supplied by an evaporating dryer 4 and the solid content in the waste liquid is made into a powder. This powder is sent to a solidifying teatment 11 by a screw feeder 10 via a detecting part 9 of an electric resistance type detector 8. In a case when the inner parts of the evaporating dryer is washed, the washing liquid is supplied to a spray nozzle 14 from a washing liquid line 12 via a flowmeter 13, and is washed by ejecting. The washing liquid washes off the powder adhered on the dryer and the inner wall of a hopper 7, and is collected by a drain tank 15 by means of passing the screw feeder via the detecting part 9 of the electric resistance type detector 8. The electric resistane type detector 8 detects both of the extent of the dehumidity of the drying powder and the washing effect of the washing process.
