Abstract

The invention provides a device for producing diesel oil through catalytic distillation of waste engine oil. The technical scheme of the device is described as follows: a heating furnace (1) is connected to a fractionation reaction column (2). A pipeline on the top of the fractionation reaction column (2) is connected to a liquid separating pot (4) through a condenser (3). The liquid separating pot (4) is connected to a vacuum pump (5). A middle-upper pipeline on the fractionation reaction column (2) is connected to a diesel oil pot (8) through a first heat exchanger (6) and a first cooler (7). The diesel oil pot (8) is connected to a diesel oil pump (9). A middle pipeline of the fractionation reaction column (2) is connected to a middle oil pot (12) through a second heat exchanger (10) and a second cooler (11). The middle oil pot (12) is connected to a middle oil pump (13). A bottom pipeline of the fractionation reaction column (2) is connected to a heavy oil pump (16) through a third heat exchanger (14) and a third cooler (15). The device is reasonable and practical in design, solves a problem that impurities cannot be effectively removed in the prior art and meanwhile solves a problem of environmental pollution.

Description

technical field [0001] The invention relates to the technical field of producing diesel from waste engine oil, in particular to equipment for producing diesel through catalytic distillation of waste engine oil. Background technique [0002] Waste engine oil is industrially used waste lubricating oil and mechanical oil containing a large amount of impurities, which has become a polluting site that is harmful to the environment. The annual production volume in my country is more than 10 million tons. How to deal with waste engine oil has become an urgent problem to be solved. Waste engine oil can be recycled by removing impurities through dehydration, filtration, precipitation, distillation, acid, alkali, and clay refining. Although there is a waste engine oil treatment device in this respect at present, the use effect is not good, and impurities cannot be effectively removed. Contents of the invention [0003] The purpose of the present invention is to provide a kind of eq...
