Description

Technical Field

[0001] The utility model relates to the technical field of waste mineral oil treatment equipment, in particular to a waste mineral oil treatment fractionation tower. Background Art

[0002] Waste mineral oil refers to mineral oil extracted and refined from petroleum, coal, and oil shale. During the mining, processing, and use process, the original physical and chemical properties have changed due to external factors, and it cannot be used anymore. The mixture fractionation equipment is used to separate mixtures with different boiling points. By distilling a mixture multiple times, the low-boiling-point component is evaporated and condensed into liquid by using the different boiling points of the components in the mixed liquid or liquid-solid system, while the residue contains a large amount of high-boiling-point components (difficult-to-volatilize components), so as to separate the mixture into relatively pure single substances. The mixture fractionation equipment is usually a fractionation tower, and the fractionation process is to allow the mixture material to enter the tower body from the middle of the tower, and the gas generated by the reboiler is transferred to each other in the tower body. The low-boiling-point component gas rises to the top of the tower, and part of the gas enters the condenser to condense into liquid and enters the tower body again. This process requires many connecting pipes for gas transportation, which makes it difficult to fix the external equipment. The collision of external objects will cause the pipeline to shake or even damage. Under the influence of gravity, the pipeline is also prone to deformation for a long time. At the same time, the waste mineral oil without fractionation cannot be effectively fractionated continuously, and manual recovery and discharge are required. In view of the above problems, the inventors proposed a waste mineral oil disposal distillation tower to solve the above problems. Utility Model Content
