Abstract

PURPOSE:To drastically suppress the generation of smells by superheated decomposition by providing a stirring means moving along a part of the inside wall of an evaporating means to the inside of said means so that the superheated decomposition of a concentrate is averted and the concentrate can be heated to a sludge state. CONSTITUTION:The stirring body 23 provided in the evaporating means 1 is moved along the inside wall of the evaporating means 1 and while the concentrate of the waste photographic processing liquid in the evaporating means 1 is stirred by this stirring body 23, the concentrate is heated by a heating means 3 provided to the outer circumference of the evaporating means 1. The inside of the evaporating means 1 is maintained in a reduced pressure state by a pressure reducing means 23 at the time of evaporation concn. and the constant temp. heating to lower the evaporation temp. is executed. The gas generated by heating of the waste photographic processing liquid is taken out of the evaporating means 1 to the outside by a discharge pipe 10. The concentrate generated by heating of the heating means 2 is stirred by the stirring body 23 in such a manner, by which the evaporation efficiency of the concentrate is improved and the superheated decomposition of the concentrate is obviated even if the liquid is concentrated to the sludge state. The generation of the smells of hydrogen sulfide, etc., is thus suppressed.

[Detailed Description of the Invention] [Industrial Field of Application] This invention deals with the evaporation treatment of waste liquid (hereinafter referred to as photographic processing waste liquid or waste liquid) generated during the processing of photographic light-sensitive materials by an automatic photographic processor. The present invention relates to a processing device, and particularly to a processing device for photographic processing waste liquid suitable for processing by being disposed in or near an automatic processor.

In photographic processing in which a large amount of light-sensitive material is processed, the components consumed during processing are replenished, while the components that are concentrated by elution or evaporation into the processing solution (
For example, methods are used to maintain the performance of the processing solution at a constant level by removing bromide ions in the developer and silver complex salts in the fixing solution and keeping the processing solution components constant. Therefore, a replenisher is added to the processing solution, and a portion of the processing solution is discarded to remove thickening components in photographic processing.

In recent years, systems have been changing to systems in which the amount of replenishment, including washing water, which is a replenishment solution for washing, has been significantly reduced due to pollution and economic reasons, or photographic processing waste liquid is removed from the processing tank of automatic processors. It is led through a waste liquid pipe, diluted with waste liquid from washing water, cooling water from automatic processors, etc., and then disposed of in sewers, etc.

However, due to stricter pollution regulations in recent years, it is possible to dispose of washing water and cooling water into sewers or rivers, but it is possible to dispose of washing water and cooling water into sewers or rivers, but it is not possible to dispose of washing water and cooling water into sewers or rivers. It has become virtually impossible to dispose of liquids (or bleaching solutions, fixing solutions) and stabilizing solutions. For this reason, each photo processing company pays a collection fee to a specialized waste liquid collection company to collect the waste liquid, or installs pollution treatment equipment. However, the method of outsourcing to a waste liquid treatment company requires a considerable amount of space to store the waste liquid, and is also extremely expensive. Furthermore, pollution treatment equipment has drawbacks such as extremely large initial investment (initial cost) and the need for a fairly large space for maintenance. Therefore, in general, waste liquid is collected by a waste liquid collection company and rendered harmless through secondary and tertiary processing, or the price of waste liquid collection is increasing year by year due to rising collection costs, and collection efficiency is low in minilabs etc.
It is difficult to get people to come and collect the liquid, and this causes problems such as waste liquid filling the store.

[Section B to be solved by the invention] By the way, when photographic processing waste liquid is evaporated in this way, harmful or extremely foul-smelling gases such as sulfite scum, hydrogen sulfide, and ammonia gas are generated. This is due to the decomposition of specific sulfur compounds, such as thiosulfate and sulfite, which are often used in fixers and bleach-fixers contained in photographic processing waste solutions.

For this reason, various studies and experiments have been conducted to remove odor components, and it has been found that the photographic processing waste liquid is evaporated and concentrated when heated by the heating means, but the resulting concentrate is not heated by the heating means.
