Embodiment 1

[0046] Such as figure 1 As shown, a device for removing impurities and dehydrating waste engine oil by applying compound field force, including: reaction tank 11, liquid distributor 1, drain pipe 2, seepage hole 12, liquid input pipe 3, insulating suspension plate 4, electrode plate , High-pressure introduction pipe 6, high-pressure connecting bellows 7, automatic frequency conversion voltage regulator 8, liquid output pipe 9 and ultrasonic generation pipe 10.

[0047] The reaction tank 11 adopts a horizontal 50m 3 Standard storage tanks are manufactured and processed in accordance with GB150-2011 "Pressure Vessels". The tank body should be insulated with thermal insulation materials, and the outer casing of the tank should be grounded for insulation treatment. The thermal insulation materials and insulation treatment methods are implemented in accordance with GB150-2011 "Pressure Vessels".

[0048] Drainage pipe 2 is arranged around the inner bottom of reaction tank 11, ado...

Abstract

The invention discloses a method and a device for impurity removal and dehydration of waste engine oil by applying composite field force. The waste engine oil is distributed into a reaction tank, an ultrasonic sound field effect and an electric field effect are applied to the waste engine oil, the waste engine oil is crushed into fine oil drops, water drops and mechanical impurities under the combined action of three field forces including gravity field force, electromagnetic force and ultrasonic force in the reaction tank, and the fine oil drops, the water drops and the mechanical impurities are separated to different positions in the reaction tank. The oil drops float upwards and are discharged from the upper part of the reaction tank, the water drops accumulate at the bottom of the tank and are discharged from the bottom of the tank, and the mechanical impurities accumulate on an electrode plate and can be regularly cleaned. The method and the device are high in waste engine oil impurity removal and dehydration efficiency, high in impurity removal speed, good in adaptability and simple in structure, and the process parameters of the device can be flexibly adjusted. The method and the device are not only suitable for impurity removal and dehydration of waste engine oil, but also suitable for impurity removal and dehydration of product oil of different types and different characteristics, so that a better impurity removal and dehydration effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of waste engine oil treatment, and in particular relates to a method and a device for removing impurities and dehydrating waste engine oil by applying compound field force. Background technique [0002] Waste engine oil refers to the engine oil mixed with impurities such as water, dust, other miscellaneous oils and metal powder produced by machine parts wear during use. The second refers to the engine oil that has gradually deteriorated due to a long service life, producing organic acids, asphalt and other substances, and does not meet the relevant standards for use. According to GB / T 7631.1-2008 "Classification of lubricants, industrial oils and related products (Class L)", it can be divided into four categories: waste internal combustion engine oil, waste gear oil, waste hydraulic oil and waste special oil. Its main components are organic hydrocarbons, such as aging oil, paraffin, asphalt, etc.; there are...
