　　sketch:

　　Many processes in industrial processing involve the use of thin oil for lubrication, cooling, and other purposes. Oil that is recycled for a long time contains moisture and small particles such as metal powder. The high-speed fully automatic oil purification system produced by Ruite Environmental Protection can effectively separate water from oil and remove fine particles. Thus extending the service life of oil products. This type of oil purifier can remove metal particles as small as 1 micron and organic particles as small as 5 microns. After separation, the remaining moisture in the oil is less than 0.3-0.5% (by volume).

　　Waste oil regeneration

　　Refineries generate various types of dirty oil - so-called waste oil - during the production process. They come from the processes of venting, draining, and cleaning, especially for cleaning the bottom of oil tanks. Most of these dirty oils contain a high proportion of oil, which can be mixed with crude oil and processed in refineries. If waste oil is treated, not only can the cost of cleaning waste oil be reduced, but oil can also be recovered from waste oil, thereby generating profits.

　　Under normal circumstances, it needs to be purified to obtain an oil phase. The aqueous phase can also be further separated and treated at a lower level to avoid the treatment cost of oily wastewater.

　　Typical scope of supply

　　1. Three phase spiral centrifuge used for processing waste oil

　　2. Using a disc centrifugal separator to finely separate the oil phase, as the oil phase contains a large amount of crude oil that can be further processed in the refinery

　　3. The aqueous phase can be further treated in existing sewage treatment plants

　　4. The cleaning fee is only for the separated solids

　　Explanation of the Separation Principle and Development History of Three phase Horizontal Spiral Centrifuge for Waste Engine Oil Purification and Regeneration Equipment:

　　In China, the earliest production was the two-phase decanter centrifuge, also known as the solid-liquid separation centrifuge. The two-phase decanter centrifuge is further divided into solid-liquid separation, liquid-liquid separation, solid-phase concentration, particle wet classification, and sealed explosion-proof. Different mechanisms have different processing requirements and uses for the centrifuge, and the design parameters have been adjusted accordingly. For example, the centrifuge used for sludge dewatering is not suitable for liquid-liquid separation, and the centrifuge used for dye grading is not suitable for separating flammable and explosive materials. Therefore, the selection of two-phase horizontal screw centrifuge is very important and must be finalized according to specific production process requirements. In the later stage, the three-phase decanter centrifuge evolved from the two-phase decanter centrifuge and was developed. Abroad, the three-phase decanter centrifuge is mainly used in the energy industry, especially in the petroleum industry. The principle of a three-phase horizontal screw centrifuge is the separation of solid, liquid, and liquid phases, commonly known as the separation of oil, water, and slag phases. In this way, one three-phase horizontal screw centrifuge can solve the separation of three materials at once.

　　The separation principle of oil-water residue is to separate one solid phase (density) from two liquid phases with different densities. The drum and screw rotate at high speed in the same direction with differential speed, and the material enters through the feeding pipe. Under the action of centrifugal force, solid phase materials deposit on the drum wall to form a sediment layer. Two types of liquid phase materials form a light liquid phase ring and a heavy liquid phase ring, respectively. Starting from the drum wall, a solid phase layer, a heavy liquid phase layer, and a light liquid phase layer are formed in sequence inward. The spiral continuously pushes the solid material deposited on the drum wall to the cone end of the drum and discharges it outside the machine through the slag discharge outlet. The light liquid phase and heavy liquid phase continuously overflow from different overflow ports at the large end of the drum. Thus achieving three-phase separation.

　　At present, our company's waste oil purification and regeneration equipment, three-phase horizontal screw centrifuge, and oil-water slag three-phase separation equipment have been applied in multiple provinces in China. Our cooperative units include dozens of large enterprises such as Sinopec, PetroChina, Daqing Oilfield, Liaohe Oilfield, Huabei Oilfield, and China Railway Bureau. We can provide practical cases for everyone to investigate.
