Problems solved by technology

[0005] In view of the above-mentioned related technologies, the inventors believe that, in the plate-making and developing process, photocopied plates need to be washed frequently, and the amount of waste water after plate-washing is huge, and only relying on a single heating roller to solidify and separate the developing waste liquid is extremely efficient. Low

Abstract

The invention relates to the field of waste liquid treatment, in particular to a developing waste liquid treatment system which comprises a heating curing device and a steam condensing device. The heating curing device comprises a treatment tank, a frame body, a plurality of heating rollers which are rotationally arranged on the frame body and are annularly distributed, a driving mechanism for driving the plurality of heating rollers to rotate around the same horizontal axis, and a scraping mechanism for scraping off the cured waste liquid on the heating rollers, and when the heating rollers move to the lowest end, the heating rollers are located in the treatment tank; and the steam condensing device is used for condensing and liquefying the steam generated by the heating curing device. The system has the effect of improving the curing and separating efficiency of the developing liquid.

Description

technical field [0001] The present application relates to the field of waste liquid treatment, in particular to a developing waste liquid treatment system. Background technique [0002] The developer is a chemical solvent that dissolves the soluble area of ​​the photoresist caused by exposure, and is a common solvent in the plate-making process in printing. The developing waste liquid is listed as hazardous waste by the state and cannot be discharged directly. It can only be treated by a waste liquid treatment institution with national qualifications. [0003] At present, by distilling and discharging the non-toxic water in the developing waste liquid, three barrels of developing liquid can be concentrated into one barrel, so as to reduce the amount of existing waste liquid that needs to be treated and reduce the processing of developing waste liquid in printing factories. cost output. [0004] In view of the above problems, the Chinese patent application number CN20192020...
