A kind of treatment equipment and method related to inorganic membrane distillation applied to waste oil products

Abstract

The invention relates to the technical field of waste oil treatment and particularly relates to a processing device and method for applying inorganic membrane distillation to a waste oil product. The processing device comprises a vacuum pump, an oil-water separator, a vacuum tank, a membrane distillation tank, a cycle heating tank, a preprocessing tank, a feeding pump and an electronic particle accumulator, wherein a waste oil inlet pipeline is connected with the feeding pump, the other end of the feeding pump is connected into a cavity in the upper part of the preprocessing tank, and a filter core is arranged in the cavity of the preprocessing tank. According to the processing device, by combining an inorganic membrane decompression distillation technique with a gradient filtering technique and an electrostatic adsorption technique, moisture and various pollutants in waste oil are completely separated without damaging the original properties of the oil product, so that the regeneration and the recycling of the waste oil are realized. Compared with the prior art, the processing device has the advantages that the resource regeneration and the recycling are carried out by utilizing a membrane-distillation waste oil regeneration processing system, so that the circular economy is realized; the device is simple in process, low in energy consumption, strong in applicability, high in recovery rate, wide in application range, easy to operate, environmentally-friendly and suitable for various different oil products.

Description

[technical field] [0001] The invention relates to the technical field of waste oil treatment, in particular to a treatment equipment and method related to inorganic membrane distillation applied to waste oil products. [Background technique] [0002] Waste oil is divided into two categories: waste lubricating oil and waste fuel oil. Waste lubricating oil generally refers to lubricating oil being polluted by oxidation, thermal decomposition and polymerization, metal abrasive particles and moisture impurities intruding from the environment during the use of lubricating oil, which makes the lubricating oil darker and the acid value rises. The resulting sediment, sludge, colloid and metal abrasive particles will lose the proper lubrication, sealing, cooling, shock absorption and other protective effects on the machine, so they need to be replaced. These replaced oils are collectively called waste oil. There are many sources of waste lubricating oil, such as waste lubricating oil...
