REGENERATING APPARATUS OF CLEANING SOLUTION BY USING TUBULAR MEMBRANE

摘要

The present invention is to instantaneously vibrate the foam potential of the contaminants surface by supplying an AC current of a very small amount in the flow direction of the treated water in order to reuse as process water to remove the cleaning liquid contaminants of the steel degreasing step and recovery and accelerate the coalescence phenomena by varying the difference in specific gravity to separate the suspended materials combined with the oil to improve the processing can separate recovery efficiency from the contaminants and on the strip degreasing cleaning liquid reprocessing apparatus using a tubular separator of continuous filtration by a suitable membrane in the lung rinse solution that, the pressing portion pre-processing unit (10, which isolates was injured lung washings in the inflow oil and suspended solids is mixed with pressurized air is mixed with the injected from the pressure tank 31 is lipophilic agglomeration plate 13 is provided )Wow; The difference in specific gravity by increasing the particle size of the waste cleaning liquid flows so as to reverse the polarity alternately and having a plurality of electrode plate 21 connected to the output of the AC power generating unit 50 from the pressed portion preprocessor 10 charge agglomerated pre-processing unit 20 to separate the contaminants and by; The treated water from the inlet via the circulation tank 40 charges aggregated pre-processing unit 20 is configured, characterized in that obtained by having a tubular separator 60 for separation into filtrate and concentrate, in the pressure tank (31) be pre-produced for introducing the air is sucked by the pressurizing pump 32, the pressure of the pressure injected by the pressure control valve 33 is kept constant, the agglomeration plate 13 includes a plurality of interval binary wrinkles the caught comprises a parallel plate.
