FIELD: chemistry. ^ SUBSTANCE: present method is intended for utilisation of waste oil resources. Method consists in that non-refined waste motor oil is added to Diesel fuel, then centrifugal purification of the obtained mixture is carried out with its separation into fractions as follows: heavy liquid, light liquid and hard. Before centrifugal purification fuel-oil mixture can be subjected to the action of ultrasound field with frequency of 2028 kHz during a time period necessary for obtaining homogenous structure. Fuel and oil are preferably taken in ratio of 3:1 to 100:1. In the device for waste oil utilisation, unit of dosed supply is connected with ultrasound mixer, and unit of separation into fractions is made as acentrifugal purifier capable of separating mixture into three fractions, i.e. heavy liquid, light liquid and hard. Unit of separation into fractions contains the second centrifugal purifier connected with the first one. The first purifier is made with a cone insert, which ensures coarse purification, the second one being made with a cylinder insert, which ensures fine purification. ^ EFFECT: simplification of technology and construction of device for waste oil utilisation, increase in purification quality with reduction of time. ^ 8 cl, 2 tbl, 1 dwg. |
