Product parameters

Features

This equipment adopts the world's latest microfiltration purification technology, and the whole machine has no filter element and no high-speed rotating motor (non-centrifugation). There is no need to replace the filter material (solving the troubles caused by the frequent replacement of the filter element and filter paper in the traditional oil filter during use, as well as the long-term capital investment of purchasing filter material). This equipment adopts pure physical purification, so that the floating substances in waste oil such as grease, oxidized chromosomes and other impurities insoluble in gasoline and benzene can be completely removed (that is, impurities that cannot be filtered by vacuum oil purifiers), which greatly improves the previous performance of our company. The unique decolorized regenerated product (special for oil refinery) has problems such as large volume, high cost, and choice of installation site. At the same time, it brings together the characteristics of our company's high-efficiency vacuum oil purifier ZY, which is durable, strong in applicability, stable in performance, safe and reliable, light and flexible, and has fast oil output and high oil output rate. It is especially suitable for the regeneration, decolorization and purification of dark, red and black lubricating oil products in non-refinery plants.

The main reason for the discoloration of waste lubricating oil: waste oil contains impurities (oxide metals, naphthenic acid, aromatic hydrocarbons, polycyclic aromatic hydrocarbons, methane, etc.) that are difficult to remove. If these impurities are not removed, the oil product cannot meet the standard. Its six functions (1, lubricating, 2, cooling, 3, flushing, 4, sealing, 5, anticorrosion, 6, buffer) are unable to protect the machine. Therefore, the color change of the oil is the most fundamental manifestation of the deterioration of the oil.  

The various properties and physical and chemical indicators of its oil products are completely the same as those of new oil. The decolorization process also adopts a unique invention patent technology, which does not require pure physical purification of the acid-base process (which will wash away the additive components). The machine also has the function of oil preparation, which can be used to prepare any physical and chemical defects of lubricating oil. It has achieved unprecedented high performance and high standard equipment.

Oil-water separation: ① Under the action of vacuum negative pressure, the dirty oil forms a large-area and multi-layered vacuum drying state, so that the water in the oil, water-soluble acid or alkali, amino acid, and waste gas can be fully decomposed and evaporated, and after purification The water content and acid content of the oil reach the national new oil standard.

② The temperature of sewage oil is controlled at about 70℃ during oil-water separation, which avoids the aging of sewage oil, coking, and the decomposition of additives caused by excessive temperature during the treatment process of waste oil. control effect. (In the process of oil treatment, no sedimentation is required, and the inverse specific gravity separation method is adopted, and the separation rate reaches 100%)

Air-cooled condensation: The water vapor separated from the waste oil is condensed into water within 2 seconds until it is discharged, which solves the technology of wasting water resources by water cooling.

Gravity separation system: (for the first component and third product of oil) acid, alkali, hydrogen, ethane, ethylene, acetylene, methane, benzene, light oil, gasoline, kerosene, diesel, oxidation, carbonization, gas Coking and coking are automatically separated, with a separation rate of more than 99%, because these substances in the oil lead to a decrease in viscosity, flash point, extrusion, anti-wear, viscosity index, corrosion resistance, and oxidation resistance, and increase in density. Therefore, they are different from mechanical impurities and cannot be solved by filtration.

①Acid, benzene, methane, ethane, ethylene, light oil, kerosene, gasoline and diesel directly lead to the decrease of viscosity and flash point of oil products. ② Substances such as alkali, carbonization, gelatinization, moisture, asphaltene and other substances cause the viscosity to rise, which also directly affects the viscosity-temperature performance of the oil, resulting in a huge difference and reducing the lubricating effect.

Emulsification separation system: The emulsification of oil products is usually caused by water in the oil (such as absorption from the air, or leakage of cooling equipment due to external reasons). Oil and water can be eliminated by simple oil filter or sedimentation method. Emulsified water is difficult to eradicate. Due to the inevitable long-term contact of oil products with steam, air, and organic metal surfaces, frictional heat is generated, and some acidic substances are generated, resulting in accelerated oxidation and deterioration of oil products and corrosion of machine parts. Such as the third product naphthenic acid, gum, polycyclic aromatic hydrocarbons reduce the anti-emulsification performance of the oil. This system can completely separate and improve the anti-emulsification performance of oil products.

Special filtration system: Under the action of interfacial tension and friction, the oil produces a certain amount of metal iron foam, which cannot be solved by filtration (too much iron foam causes frequent blockage of the magnetic filter element). The system can adsorb various sizes of iron foam, and its dirt-holding capacity is 30 to 50 times that of ordinary magnetic filter elements. Electrostatic degaussing effectively filters the colloid, asphaltene and carbon residue of aging oil (a major difficulty that cannot be solved by ordinary oil purifiers), and greatly improves the cleanliness of oil products.

The whole machine has no filter screen (core) and no centrifugal effect. It adopts the magnetic electrostatic filtration technology, which has been developed by our company for many years. It automatically feeds materials and removes impurities. The operation is simpler, the oil discharge is faster and smoother, and the purification is more thorough. Lower cost, extremely low labor intensity and other features, patented components are maintenance-free for life, completely solve the pollution dilemma of various industrial oils, and get rid of the use of filter elements (nets) or vacuum oil filters for decades, which cannot filter oxidized impurities ( Incomplete filtration), the filtered oil does not dare to be used, and the filter element (net) and filter paper (cloth) are frequently replaced, resulting in the high cost and low efficiency of the filtered oil with the same cleanliness filter and non-filtering. The reality is that it saves costs and cannot contribute to society. The equipment itself is fixed and mobile, which is convenient for customers to carry.

The difference between decolorization regeneration oil filter and ordinary oil filter:

The discolored oil does not meet the standard, and the oil that meets the standard does not change color. The ordinary oil filter cannot restore the color of the oil, but the decolorization and regeneration oil filter can. The development history of the oil purifier was first to deal with oil products below 15#, using a plate-and-frame press, and in the middle stage, heating and vacuum filtration, using vacuum negative pressure, high filtration accuracy (not as good as a filter press), with degassing function, The characteristics of sedimentation and drainage further improve the quality of oil reuse. This type of equipment is currently the one with the largest production volume and users at home and abroad, that is, the most popular vacuum oil filter on the market, with different shapes and similar functions. It integrates automatic oil inlet and outlet, heating, degassing, sedimentation and drainage (not completely), and filtration, and the workload is very large (80% of the flow rate, limited by the amount of impurities), but the regenerated oil cannot meet the national new oil standard. , The target user should be a light-polluting enterprise, such as: power engine test oil, installed engine oil for repair and test, it is an economical equipment, at present, our company has developed a multi-functional decolorization regeneration oil filter, which integrates various types of equipment. The advantages are integrated, and at the same time, an automatic oil-water separation system (no sedimentation, inverse specific gravity separation method, separation rate of 100%) is added. , carbonization, gasification, emulsification, gelation and other automatic separation functions, the separation rate is up to 98%, because these substances cause the viscosity, flash point, extrusion, anti-wear, viscosity index, and corrosion performance to decrease in the oil, so they are different. For mechanical impurities, filtration cannot be used to solve the problem. At the same time, the multi-functional oil purifier can purify various liquid oils below 3000# when the natural temperature is lower than minus 30 degrees, and improve the physical and chemical indicators of oil products due to decline during use. , the acceptance standard is accepted according to the country's latest new oil national standard, which rewrites the fact that the 37.3 million tons of waste oil produced globally (since 1999) every year (an annual increase of 12.9%) needs to be recovered by the recycler to the refinery in order to regenerate new oil. History has made an indelible contribution to the industrial society!

The ambient temperature during operation of the machine is in the range of -30 to 40 °C.

When used in a low temperature environment, the vacuum pump oil must be heated to about 15 ℃ before it can be started.

The oil to be purified should not be too dirty (that is, there are too many water and impurity particles in the oil), otherwise it must be fully filtered with other filtering equipment (such as the plate and frame pressure oil filter produced by our factory), so as not to affect the net oil the degassing efficiency of the machine or clog the filter element.

The altitude of the use site will directly affect the vacuum degree of the machine.

This functional high-efficiency decolorization and regeneration oil purifier adopts enhanced lipophilic and hydrophobic technology to change the oil-water interface. The small water molecules in the oil accelerate the movement, rapidly coalesce, settle, separate, and automatically remove.

Then, the color of the oil is restored through the reaction kettle. Finally, the two-stage vacuum high-speed evaporation is used to condense and remove the trace water in the oil. During the dehydration process, the multi-stage high-precision filter material simultaneously completes the condensation to filter impurities and other harmful components.
