Cooling liquid recycling apparatus and method |
| abstract |
A method and an apparatus for recycling a used cooling liquid, which are inexpensive and can regenerate the used cooling liquid of high quality. The method for recycling a used coolant comprising water, a rust inhibitor containing an organic carboxylic acid, and ethylene glycol according to the present invention includes a step of adjusting the pH of the coolant to at least 5 or less. Separating and recovering the organic carboxylic acid by at least one of filtration and solvent extraction. You may further have process S100 which removes the oil component mixed in the cooling fluid. The organic carboxylic acid includes an aliphatic carboxylic acid and an aromatic carboxylic acid. The step S104 for recovering the aliphatic carboxylic acid by filtration and the step S106 for recovering the aromatic carboxylic acid by solvent extraction are performed. May be included. Preferably, the method further includes a step S108 for adjusting the pH to 6 to 8 and a step S110 for recovering the water-ethylene glycol solution by distillation under reduced pressure.
