Waste machine oil/tire oil/plastic oil distillation device and technique

Abstract

The invention relates to a waste machine oil / tire oil / plastic oil distillation device and technique. The waste machine oil / tire oil / plastic oil distillation device is composed of a preheater, a hot-blast furnace, a distillation still, a distillation tower, a fractionating tower, condensers, oil storage tanks, oil washing towers, filtration towers and finished product oil tanks, wherein the preheater is connected with an oil inlet of the distillation still; the hot-blast furnace is connected with the distillation still; the distillation tower is arranged on the distillation still; an oil gas outlet on the top of the distillation tower is connected with the fractionating tower; a reflux port on the lower part of the fractionating tower is connected with the distillation still; a light component oil gas port and a medium component oil gas port of the fractionating tower are respectively connected with the corresponding condensers, the condensers are respectively connected with corresponding extraction towers and the corresponding oil storage tanks; and each oil storage vessel is connected with the finished product oil tank through an oil pump, the oil washing tower and the filtration tower. The technological device is simple and convenient to operate, and has the advantages of high treatment accuracy and no leakage; the invention improves the working environment, has high production efficiency, and thoroughly eliminates secondary pollution; and the treated oil product is better than the oil product obtained by common distillation, can substitute the raw material for oil production plants for large-size ships, has high economic benefit, and can effectively save resources and energy sources.

Description

technical field [0001] The invention relates to a device and a process for obtaining more pure oil products by distillation processing waste engine oil, tire oil and plastic oil. Background technique [0002] The technology of thermally cracking waste tires and waste plastics to treat solid waste and recycle oil products has been rapidly promoted around the world. It not only eliminates the pollution of some solid waste to the environment, but also realizes the recycling of energy. Crude oil and waste engine oil produced by pyrolysis of tires and waste plastics are mostly used as thermal fuels. Because carbon black is produced during the cracking process, the carbon black enters the condensation system along with the oil gas, so the oil product is darker in color, has more impurities, and the calorific value is not high, so the utilization rate is low; and a few oil products are processed by simple distillation technology Simple treatment, this technology has low processing...

Problems solved by technology

Because carbon black is produced during the cracking process, carbon black enters the condensation system along with the oil and gas, so the oil product is darker in color, has more impurities, and the calorific value is not high, and the utilization rate is low; and a few oil products are processed by simple distillation technology Simple treatment, this technology has low processing accuracy, serious oil loss during processing, and the chemical properties of the distilled oil are unstable and easily oxidized, resulting in blackening of the oil color, serious impurities, and greater economic loss

In the distillation process, it is inevitable to produce oil residue, which endangers the safety of operators and causes secondary pollution to the environment
