Description
Technical Field
The invention relates to the technical field of water-oil separation, in particular to a water-oil primary separation device.
Background
China is a large population, is the first major textile country in the world, and most printing and dyeing enterprises are concentrated in coastal developed areas. The production process of the printing and dyeing industry is complex, and the textile needs a heat setting procedure after being dyed and rinsed.
In the shaping process, moisture carried by the fabric is heated and volatilized together with organic compounds such as solvent, grease, wax and the like, and is discharged from the exhaust funnel along with waste heat air to form the lampblack waste gas of the shaping machine. Organic steam and oil mist smoke in the oil smoke waste gas of the setting machine not only influence the health of workers and nearby residents, but also are important sources of PM2.5 in the atmosphere, and cause the quality deterioration of the ambient air.
At present, the treatment mode of the oil fume waste gas in the printing and dyeing industry is to dissolve the oil fume waste gas by water, and then the oily sewage is sent to a sewage treatment plant for sewage treatment, but the charging mode of the sewage treatment plant for sewage treatment at present charges the oil fume by ton weight of the water, and the oil content in the sewage is not in the charging standard, so that the total amount of the sewage to be treated can be reduced by increasing the oil content in the sewage, and the key point for saving the sewage treatment cost of an enterprise is realized.
