Abstract

The invention belongs to the technical field of hazardous waste treatment, and discloses a solid-liquid separation method based on bearing cleaning greasy dirt waste liquid and application. The invention provides a solid-liquid separation method based on bearing cleaning greasy dirt waste liquid. Solid-liquid separation of the bearing cleaning greasy dirt waste liquid can be completed only by adopting an environment-friendly treatment process of centrifugal separation and mild operation conditions. The invention further provides application of the solid-liquid separation method based on the bearing cleaning oil stain waste liquid in separation of the bearing cleaning oil stain waste liquid, the separated bearing cleaning oil stain waste liquid is good in stability, bearing cleaning oil and solid-phase sludge are not mixed again after oscillation, and the separation effect is excellent.

Description

technical field [0001] The invention relates to the fields of waste treatment and environmental protection, in particular to a solid-liquid separation method and application based on bearing cleaning oily waste liquid. Background technique [0002] Bearings are usually composed of bearing rings, rolling elements and cages. After the production of bearing parts is completed, kerosene is often used to clean the parts, so that the lubricant attached to the surface of the parts can be dissolved, and at the same time, the parts produced by the processing can be dissolved. The debris is removed together, thereby keeping the surface of the part clean for subsequent bearing assembly. In order to reduce costs and recycle, it is necessary to filter the cleaned kerosene to remove impurities in the kerosene. However, due to the different sizes of the debris, the kerosene after a single filtration still contains a large amount of fine metal debris, which cannot be reused. If the filtrat...
