Abstract
An apparatus for treating a waste solution which contains a nonvolatile substance such as a toner used for development of an electrophotographic film and a liquid which is difficult to volatilize at normal temperatures such as isoparaffin. The waste solution heated from below a multiplicity of vertically elongated guide chambers disposed in a waste solution container rises upward through the guide chambers in the form of vapor and is oxidized by a catalyst. After ignition, even if the heating of the waste solution by a heater is stopped, the waste solution in the waste solution container continues to be heated by oxidation heat.
Claims18
A waste solution treatment apparatus comprising:
- a waste solution container and mans for supplying a waste solution to said container;
- heating means provided below said container for vaporizing a portion of said waste solution supplied to said container;
- a catalyst for catalyzing said vaporized portion of said waste solution;
- an igniter for igniting said vaporized waste solution and having a portion adjacent to said catalyst;
- guide means comprising a plurality of hollow, elongated, open ended chamber located within said container and partially immersed in said waste solution, said guide means being disposed vertically between said heating means and said catalyst, for guiding said vaporized waste solution to said catalyst and for transmitting heat generated at said catalyst to said waste solution thereby maintaining the temperature of said waste solution;
- and
- an air intake means provided for said waste solution container, above said catalyst, for supplying air to said catalyst.
