Pretreatment device for refining biodiesel oil by adopting illegal cooking oil

Abstract

The invention provides a pretreatment device for refining biodiesel oil by adopting illegal cooking oil, relates to the field of treatment of the illegal cooking oil, and solves the problem that the purity of the biodiesel oil is affected by incomplete removal of water debris during treatment of the illegal cooking oil. The pretreatment device comprises a preheating device and a filter, and further comprises an oil-water separator, wherein the oil-water separator further comprises a waste oil feeding pipeline, a rotating tank, a motor rotating shaft, a driving gear, a rotating tank rotating shaft, a driven gear, five bearings, a motor and a first switch valve; the waste oil feeding pipeline is connected with the rotating tank through the bearings in a rotatable manner; the rotating tank rotating shaft and the rotating tank are of an integrated structure; the driven gear is arranged on the rotating tank rotating shaft; the driving gear is arranged on the motor rotating shaft; meanwhile,the end, far away from the motor, of the motor rotating shaft is connected with the inner wall of the oil-water separator through the bearings in a rotatable manner; the driving gear is meshed with the driven gear to transmit rotation. By implementation of the scheme, the water debris in the illegal cooking oil can be treated, so that the biodiesel oil refining efficiency and the purity of a finished product are improved, and the economical benefit is increased.

Description

technical field [0001] The invention discloses a pretreatment device for refining biodiesel from waste oil, which belongs to the field of waste utilization, and more particularly relates to a pretreatment device for refining biodiesel from waste oil. Background technique [0002] Biodiesel is a cleaner synthetic oil commonly used in tractors, trucks, ships, etc. It refers to oil crops such as soybeans, rapeseed, cotton, palm, etc., wild oil plants and engineering microalgae and other aquatic vegetable oils, animal fats, and catering waste oils, etc. Regenerative diesel fuel from petrodiesel. Biodiesel is a kind of biomass energy, which is close to petrochemical diesel in physical properties, but different in chemical composition. Biodiesel is a mixture of complex organic components with extremely high oxygen content. These mixtures are mainly organic compounds with large molecular weight, including almost all kinds of oxygen-containing organic compounds, such as: esters, e...
