Description

Technical Field

[0001] The utility model relates to a waste oil purification device, and more particularly to a waste oil flocculation, filtration and regeneration device. Background Art

[0002] Waste oil refers to oil that has been used for a period of time and cannot be used due to the infiltration of contaminants and the oxidation and deterioration of some components. This category primarily includes waste engine oil, waste hydraulic oil, waste cutting oil, waste cold rolling oil, and other waste mineral oils generated in the automotive, machining, and equipment manufacturing industries. The total amount of harmful impurities in waste oil typically ranges from 5% to 35%, with the remaining 65% to 95% consisting of oil components. The traditional waste oil regeneration process involves initial filtration of the waste oil—heating and dehydrating the waste oil at high temperatures (100-150°C)—gasification and cracking of the waste oil at high temperatures (300-500°C)—high-temperature distillation of the oil and gas—staged cooling of the oil and gas to convert them into fuel and base oil—and separate storage of the fuel and base oil. A vacuum oil purifier is a very popular waste oil regeneration device. It degasses and dehydrates the oil under certain vacuum conditions and uses specialized filter media to remove mechanical impurities, thereby purifying the oil. The present utility model has invented a variety of waste oil regeneration devices, such as the "Waste Oil Purification and Decolorization Integrated Machine", with patent application date of June 19, 2009, and patent number ZL 2009 1 0104131.3; the "Waste Oil Vibration Filtration Vacuum Oil Purifier", with patent application date of March 15, 2012, and patent number ZL 2012 1 00 67636.9; and the "Waste Oil Rapid Purification and Decolorization Integrated Device", with patent application date of September 21, 2016, and patent number ZL 2016108358678. In the past, waste oil regeneration systems had three major drawbacks. First, the regeneration system was complex, requiring components such as filter tanks, reactors, adsorption towers, catalytic towers, distillation towers, fractionation towers, vacuum components, and storage tanks. Second, the waste oil needed to be heated to high temperatures (100°C-500°C) during regeneration, significantly damaging its quality. Third, the regenerated oil had already undergone a qualitative change. When tested against the original oil's specifications, most of the indicators failed to meet these standards, forcing the regenerated oil to be used only as fuel or base oil. In recent years, efforts have been underway to simplify waste oil regeneration equipment, conduct low-temperature regeneration (below 100°C), and ensure that the regenerated oil's specifications closely match those of the original oil. A new waste oil flocculation and filtration regeneration process has been initially developed, leading to the development of a waste oil flocculation and filtration regeneration system.

The mesh size of the mixed raw materials is 80-250 mesh, and the ratio of waste oil to waste oil regeneration flocculant is 1000:2-50.

[0008] The waste oil flocculation, filtration and regeneration device and the waste oil regeneration flocculant are composed of the following raw materials in parts by weight: 20-40 parts of hydroxy cellulose, 5-8 parts of silica gel, 10-12 parts of calcium carbonate, 2-4 parts of phenolic formaldehyde, 30-50 parts of chimney ash, 30-40 parts of soapberry ash, 8-12 parts of polyferric sulfate, 10-15 parts of sulfonate, and 5-10 parts of alkylbenzene sulfonic acid.

[0009] The waste oil flocculation filtration regeneration device comprises a filter layer in the filter tank consisting of an upper layer of waste oil regeneration filter and a lower layer of a support plate. The waste oil regeneration filter is mainly composed of a mixture of the following raw materials, by weight: 10-20 parts of calcite, 30-50 parts of quartz stone, 30-40 parts of activated carbon, 40-60 parts of zeolite, 70-100 parts of volcanic rock, and 10-15 parts of polyvinyl alcohol.

The equipment for this process primarily consists of a flocculation tank, a filter tank, a vacuum assembly, and a receiving tank. Its basic process: waste oil → flocculation tank → heating at low temperature (25°C-95°C) → adding a waste oil regeneration flocculant in proportion → flocculation → transferring clarified oil from the flocculation tank to the filter tank → filtration → transferring regenerated oil to a receiving tank → storage. The waste oil flocculation, filtration and regeneration device of this utility model can regenerate a variety of waste oils. When regenerating different types of waste oil, process parameters such as temperature, time, type and dosage of waste oil regeneration flocculant, type and dosage of waste oil regeneration filter, and vacuum level need to be appropriately adjusted based on the type of waste oil, degree of contamination, and quality requirements.

[0016] This new waste oil flocculation and filtration regeneration device has been tested in a new waste oil flocculation and filtration regeneration process, demonstrating exceptional results.

The waste oil regeneration speed is also relatively fast, and the cost of waste oil regeneration is significantly reduced. Trials have demonstrated a waste oil regeneration rate exceeding 90%, with regenerating one ton of waste oil costing approximately RMB 300.

[0017] The waste oil flocculation filtration regeneration device of the present invention is applied to a new waste oil flocculation filtration regeneration process. When treating waste No. 46 anti-wear hydraulic oil from a certain Chongqing Iron and Steel (Group) Co., Ltd., the closed-cup flash point, open-cup flash point, water separability, copper corrosion, kinematic viscosity, viscosity index and other indicators of the regenerated oil were repeatedly tested, and the indicators fully met the corresponding indicators of the new No. 46 anti-wear hydraulic oil.

[0018] Beneficial effects of the present invention: Compared with the waste oil regeneration device in the past, the waste oil flocculation filtration regeneration device of the present invention has four major advantages: First, the regeneration device of the present invention is simpler in structure than the waste oil regeneration device in the past, and the equipment investment is significantly reduced; second, the regeneration device of the present invention adopts low temperature to regenerate the waste oil, which does not damage the quality of the oil and has low energy consumption, while the waste oil regeneration device in the past adopts high temperature to regenerate the waste oil, which damages the quality of the oil and has high energy consumption; third, the regenerated oil produced by the regeneration device of the present invention has more than 95% of the indicators restored to the original new oil. The waste oil regeneration device of the present invention significantly improves the quality of the regenerated oil. Conventional waste oil regeneration devices only achieve about 30% of the original oil's performance, and such regenerated oil can only be used as fuel or base oil. The waste oil flocculation and filtration regeneration device of the present invention significantly improves the quality of the regenerated oil. Fourthly, the regeneration device of the present invention significantly reduces the cost of waste oil regeneration compared to conventional waste oil regeneration devices. The present regeneration device costs approximately RMB 300 to regenerate one ton of waste oil, while conventional waste oil regeneration devices cost approximately RMB 700. This regeneration device of the present invention has great promotional value. BRIEF DESCRIPTION OF THE DRAWINGS
