Waste mineral oil distilling equipment

Abstract

The invention provides waste mineral oil distilling equipment, which comprises a reaction kettle, a distilling tower, an external oil-conveying pipeline, an oil-jetting pipeline, a condenser, an oil collecting tank, an oil filling tank, a heating unit, a nitrogen making unit and a vacuum unit, wherein the distilling tower is arranged above the reaction kettle, and is connected with the condenser; one end of the oil collecting tank is connected with the condenser through a pipeline, and the other end of the oil collecting tank is connected with the vacuum unit through a pipeline; one end of the external oil-conveying pipeline is connected with the oil filling tank, and the other end of the external oil-conveying pipeline is connected with the oil-jetting pipeline positioned inside the reaction kettle; the heating unit is used for supplying heat energy to the distilling tower and the external oil-conveying pipeline; the nitrogen making unit extends into a nitrogen filling pipe inside the reaction kettle, and is used for conveying nitrogen into the reaction kettle. Under the pulling action of the vacuum unit and the pushing and stirring actions of the nitrogen making unit, the output and the yield of a finished product can be increased, and the cost is lowered.

Description

technical field [0001] The invention relates to the field of oil refining, in particular to waste mineral oil distillation equipment. Background technique [0002] Since mineral oil and the like are non-renewable resources, and, in the process of use, the waste of oil products, the global energy crisis, etc., the regeneration and extraction of waste mineral oil has become more and more important. The traditional waste mineral oil distillation In the refining equipment, due to the constraints of the equipment structure, such as the inaccurate temperature control of the heating equipment, the segmental control during the refining process is not accurate, and because the oil and gas will be subjected to many resistances during the movement process, the temperature will drop, and then flow back. To prevent this phenomenon, the traditional method is to add some insulation materials to the outer wall of the distillation tower, but the effect of this is not ideal. In the traditiona...
