Abstract

The invention discloses emulsion recycling, purifying and regenerating equipment and method. The equipment comprises a Y-shaped filter, a dosing tank, metering pumps, a pipeline mixer, a multiphase medium pump, an ozone generator and a copolymerization and separation device, wherein the interior of the copolymerization and separation device is divided into four zones, namely a hybrid reaction zone in which baffle plates are located, an upper floating oil sludge separation zone above the baffle plates, a purification liquid collecting zone on the peripheries of the baffle plates and an outermost floating oil sludge collecting and separating zone; a purified emulsion collecting pipe, the baffle plates and a floating oil residue collecting and discharging pipe are installed inside the copolymerization and separation device from bottom to top in sequence. The purifying and regenerating method comprises the steps of filtration, agent addition and mixing, pressurization for gas dissolving, ozone sterilization, solid-liquid separation and liquid and residue discharge. The equipment and the method have the beneficial effects of achieving online recycling, purifying and using of the emulsion, prolonging the service cycle of the emulsion, reducing waste emulsion output and being beneficial for reducing the production cost and protecting the water environment.

Description

technical field [0001] The invention belongs to the technical field of industrial wastewater purification, and in particular relates to an emulsion purification method and equipment in mechanical processing. Background technique [0002] Emulsion plays the role of cooling, lubricating, cleaning and rust prevention in machining, steel manufacturing, bearing processing and other processes. Emulsion is one of the metal processing lubricants used in large quantities in the locomotive and automobile manufacturing industries. It has good lubricity, cooling and cleaning properties, and is widely used in various cutting processes. However, its biggest disadvantage is that it is easily corrupted and deteriorated during use, the stability of the working fluid is poor, and the service life is short. Have to change new liquid frequently, discharge waste liquid. It not only increases the production cost, but also pollutes the environment. Waste emulsion (HW09) is one of the 47 types o...
