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.

を用いた工程を組合せて行なわれている。[Prior Art] In general, photographic processing of silver halide photographic materials includes development, fixing, washing, etc. in the case of black and white materials, and color development, bleach-fixing (or bleaching, fixing, etc.) in the case of color photographic materials. ), washing with water, stabilization, and other functions using a processing liquid having one or more functions.

されている。In photographic processing in which a large amount of light-sensitive material is processed, it is important to consider how to replenish the components consumed during processing, and how to replenish components that are eluted into the processing solution or concentrated by evaporation during processing (for example, bromide ions in the developer, bromide ions in the fixer, etc.). A method is used to maintain the performance of the processing solution at a constant level by removing substances (such as silver complex salts) and keeping the processing solution components constant. A portion of the processing solution is discarded to remove concentrated components.

。In recent years, systems have been changing to systems in which the amount of replenishment fluid, including washing water, which is used as a replenishment fluid for washing, has been significantly reduced due to pollution and economic reasons, but photographic processing waste fluid is removed from the processing tank of automatic processors. The liquid is led through a waste pipe and is disposed of in a sewer or the like without being diluted with waste liquid from washing water or cooling water from an automatic processor.

点を有している。However, due to the tightening of pollution regulations in recent years, it is not possible to dispose of washing water and cooling water into sewers or rivers. It has become virtually impossible to dispose of bleach-fix solutions (or bleach-fix solutions, stabilizers, etc.). For this reason, each photo processing company pays a collection fee to a specialized waste liquid processing company to collect the waste liquid, or installs pollution treatment equipment. However, the method of outsourcing to a waste liquid treatment company is
A considerable amount of space is required to store the waste liquid, and it is also extremely expensive in terms of cost and efficiency.Furthermore, the initial investment (initial cost) for pollution treatment equipment is extremely large, and it is quite expensive to maintain. It has disadvantages such as requiring a large space.

い、作業環境上極めて好ましくないことか起こる。In order to solve these problems, research has been conducted into heating the photographic processing waste liquid to evaporate the water to dryness or solidify it, with the aim of making it easier to process the photographic processing waste liquid even in minilabs. , Utility Model Application No. 60-70841, etc. By the way, research by the inventors has shown that when photographic processing waste liquid is evaporated, harmful or extremely malodorous gases such as sulfur dioxide gas, hydrogen sulfide, and ammonia gas are generated. It has been found that this is caused by the decomposition of ammonium thiosulfate and sulfites (ammonium salt, sodium salt, or potassium salt), which are commonly used as fixing solutions and bleach-fixing solutions in photographic processing solutions, due to high temperatures. Furthermore, during the evaporation process, moisture and the like in the photographic processing waste liquid becomes vapor and gasifies, thereby expanding the volume and increasing the pressure in the evaporator. Therefore, due to this pressure, the harmful or malodorous residue leaks out of the evaporation treatment apparatus to the outside of the apparatus, causing an extremely unfavorable working environment.

No. 1 discloses a method of providing an exhaust gas treatment section such as activated carbon in the exhaust pipe section of an evaporation treatment device. However, this method has the serious drawback that the water vapor from the large amount of water in the photographic processing waste liquid condenses or condenses in the exhaust gas treatment section, covering the residue absorption processing agent with moisture and causing it to instantly lose its gas absorption ability. Therefore, it could not be put to practical use.

及び装置について先に提案した。[Invention or problem to be solved] In order to solve these problems, the inventors provided a cooling condensing means to condense the vapor produced by evaporation when photographic processing waste liquid is evaporated, and further condensed it. We have previously proposed a method and apparatus for concentrating photographic processing waste liquid, in which the condensate produced by the process is treated, and non-condensed components are also treated before being discharged to the outside.

かあり、その分装置か大型化すると共に、製作コストが
嵩む。However, we have discovered that this proposal has the following problems. In other words, if the vapor produced by the evaporation process is condensed by the cooling condensing means, or if the cooling condensation efficiency is poor, the proportion of vapor released outside the device without being condensed will be high. Even though
The rate at which foul-smelling and harmful gases are released to the outside of the device also increases. Therefore, it is necessary to use a large-sized cooling and condensing means, which increases the size of the device and increases the manufacturing cost.
このため、この発明者等はこの凝縮液の公害負荷を軽減

することを見い出した。For this reason, the present inventors conducted various studies and experiments in order to reduce the pollution load of this condensate. It has been found that dissolving the liquid in water increases cooling capacity, improves condensation efficiency, makes the device smaller, and reduces manufacturing costs.

By dissolving the vapor produced by the evaporative concentration process of photographic processing waste into water, we can improve the condensation efficiency, reduce the pollution load of the condensate at low cost, and make it possible to downsize the equipment. The purpose is to provide processing equipment.

としている。[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a processing apparatus for photographic processing waste liquids that heats photographic processing waste liquids with a heating means to evaporate and concentrate the waste liquids. It is characterized by comprising a discharge means for taking out steam containing scum, and a dissolving means for bringing this steam into contact with water and dissolving it in the water.

止でき、しかも、冷却凝縮手段か小型になり、その分装
室が小型になると共に、製作コストか低減する。Therefore, when the steam containing gas components produced by heating the photographic processing waste liquid is brought into contact with water and the steam is dissolved in water, the cooling capacity is increased and the condensation efficiency is improved. For this reason, the proportion of steam that is not condensed and is released outside the equipment is reduced, and it is possible to prevent foul-smelling and harmful gases from being released outside the equipment.Moreover, the cooling and condensing means is small, and the separation chamber is It becomes smaller and the manufacturing cost is reduced.

よい。Further, in the photographic processing waste liquid processing apparatus of the present invention, the discharge means for taking out the vapor containing the residue components may be constructed of a pipe, and water may be poured into the pipe or blown into the water from the pipe. The use of pipes in this way simplifies the device, and the small cross-sectional area of the pipes provides high cooling capacity and good condensation efficiency.
