Description

technical field [0001] The invention relates to a low-temperature vacuum oil filter, which belongs to the field of environmental protection equipment. Background technique [0002] At present, the oil filter has been widely used in petrochemical, petroleum, coal, electric power, military machinery and other industries. It is a special equipment for removing water and gas in oil. It can effectively prevent the mechanical use oil from being mixed with water and mechanical impurities during transportation, storage and use. As we all know, impure oil has a certain impact on the performance and life of mechanical equipment. The mixing of water will cause the metal surface to rust and reduce the viscosity of the oil; the mixing of impurities will wear the working surface and leave scars on the working surface. [0003] Vacuum oil filter is a filter unit that uses vacuum evaporation-filter filter method to remove solid impurities and moisture in impure oil. The vacuum oil filter ...

AI Technical Summary

Problems solved by technology

[0005] (1) The existing oil filter needs to heat the oil to a higher temperature when the oil is separated from water. When the high-temperature oil evaporates, it will carry a large amount of compound additives in the oil, which will greatly reduce the performance of the oil itself. Moreover, high-temperature oil entering the equipment will cause deformation or damage to the mechanical structure, which will undoubtedly reduce the service life of the equipment and increase the processing cost;

[0006] (2) Existing oil purifiers generally use smaller evaporation chambers and conventional nozzles for spraying, so that the water in the oil cannot be fully evaporated, the water content in the oil cannot be quickly reduced, and the treatment efficiency is low;

[0007] (3) When the existing oil filter is separated from oil and water, a large amount of foam will be generated when the oil evaporates, and a large amount of defoamer will be consumed, and the processing efficiency will be reduced at the same time, and the performance of the defoamer on the oil itself will be changed. Cause a small amount of pollution to oil products;

[0008] (4) Most of the existing oil purifiers use multiple internal cycles to achieve the water removal effect when separating oil from water, which greatly increases the processing energy consumption and cannot achieve the purpose of online synchronous processing and synchronous use;

[0009] (5) Most of the existing oil purifiers use the in-out switch valve to control the oil in and out when separating oil from water, so that part of the heat of the heat exchanger or heater cannot be fully and effectively utilized, and the purpose of quickly separating oil from water cannot be achieved;

[0010] (6) When the existing oil filter is used for oil-water separation, most of the oil is tested offline to check whether the oil is qualified, and it is impossible to check whether the oil is qualified online in real time, which greatly increases the time and repeated costs.
