Description

Technical Field

[0001] The utility model relates to the technical field of industrial waste oil treatment, in particular to an environmentally friendly industrial waste oil purification and recycling equipment. Background Art

[0002] Industrial machinery and equipment must use various equipment oils (including hydraulic oil, gear oil, etc.), but eventually these oils will be scrapped due to mixing with water, mechanical impurities, oxidation, acidification, etc., which makes them unusable. Direct discharge of waste oil will harm the environment, and industrial waste oil needs to be recycled. Industrial waste oil treatment is a complex engineering process involving a variety of physical and chemical methods, the purpose of which is to remove harmful substances in waste oil, restore or improve its quality, so that it can be reused or discharged safely.

[0003] When the existing industrial waste oil purification equipment is used, when various reaction additives are added, the contact area between the reaction additives and the waste oil is small, and the additives are not mixed evenly in the waste oil, which reduces the chemical reaction efficiency.

[0008] Note: After the industrial waste oil treatment inside the filter reactor is completed, the suspended particles and colloidal substances will settle at its bottom. At this time, the sediment is discharged through the slag outlet. Timely removal of the sediment helps to keep the inside of the filter reactor clean and ensure the efficient progress of the industrial waste oil treatment process. The discharged sediment is temporarily stored in the waste storage box to facilitate subsequent treatment and avoid secondary pollution of the environment.

[0011] Furthermore, the plurality of through holes are evenly distributed on the inner wall of the filtration reactor along the circumferential direction, and the plurality of connecting pipes are staggeredly distributed with the plurality of through holes.

[0012] Description: By adding the through holes of the inner box and the connecting pipes of the outer box in a staggered distribution, various reaction reagents are sprayed evenly in the filter reactor, and the industrial waste oil is treated by heating reaction, which not only increases the contact area between the reaction reagents and the waste oil, but also helps to improve the uniformity and efficiency of the chemical reaction.

[0013] Furthermore, the oil quality testing instrument includes a kinematic viscometer, an acid value tester, an alkali value tester and a total sediment tester.

[0014] Note: After the oil is processed, in order to ensure that the oil meets the reuse standards, the viscosity of the oil is tested by a kinematic viscometer to ensure that the viscosity of the oil is 1.2-1.5cSt, the content of free acidic substances in the oil is tested by an acid value tester to ensure that the content of free acidic substances is 0.5-1.2mgKOH / g, the content of alkaline substances in the oil is tested by an alkali value tester to ensure that the content of alkaline substances is 0.5-1.2mgKOH / g, and the residual insoluble impurities in the oil, including suspended solids, sediments, sludge, metal wear particles, asphaltene and colloids, are tested by a total sediment tester to ensure that the upper limit of the total sediment content is 0.5%-2%.

[0015] Furthermore, a circulation pipe is provided between the temporary storage box and the filtration reactor, and a liquid pump is provided on the circulation pipe.

[0016] Note: When the oil quality testing instrument detects that the various indicators of the oil meet the reuse standards, it can be discharged from the temporary storage box for standby. When it does not meet the reuse standards, the oil can be pumped back to the filter reactor through the liquid pump and circulation pipe for reprocessing. Through strict testing procedures, the quality of the oil can be ensured to be stable, providing reliable protection for production and ensuring that the treated oil will not cause secondary pollution to the environment, promoting the recycling of resources, reducing resource waste, and having the significance of sustainable development.

[0017] Furthermore, an automatic opening and closing cover is provided at the upper end of the adding port, and an oil fume purification device is connected to the automatic opening and closing cover, and the oil fume purification device is a high-frequency electrostatic oil fume purification.

[0018] Description: When industrial waste oil is added into the filter reactor through the addition port for treatment, the automatic opening and closing cover will be closed. The oil fume generated during the treatment process will be discharged and enter the oil fume purification device for purification before being discharged, thus avoiding environmental pollution and achieving the effect of energy saving and emission reduction.
