Abstract

The invention discloses a device and a process for treating waste mineral oil. The device comprises a filtering and precipitating device, a raw material storage tank, a vacuum film evaporator and at least one molecular distiller which are successively arranged, wherein an oil discharging pipe and a sewage discharging pipe are arranged on the filtering and precipitating device; the oil dischargingpipe is connected to the raw material storage tank; the raw material storage tank is connected with a feeding opening of the vacuum film evaporator through the oil discharging pipe; a first condenser,a second condenser and a vacuum system are successively arranged at the top of the vacuum film evaporator; a reboiler is arranged at the lower end of the vacuum film evaporator; the bottom of the vacuum film evaporator is connected with the top of the molecular distiller through a first process pump; the bottom of the molecular distiller is connected with a product buffer tank; a material buffertank is arranged at the lower end of the molecular distiller. Through the adoption of the device, the waste mineral oil is directionally recycled; the treatment rate of the waste mineral oil reaches up to 99.9%.

Description

technical field [0001] The invention belongs to the technical field of waste mineral oil treatment, and in particular relates to a waste mineral oil treatment device and process. Background technique [0002] In the 21st century, mankind has entered the era of knowledge economy and circular economy. Countries around the world are taking "development of circular economy" and "establishment of a circular society" as an important way to achieve sustainable development. The circular economy requires the development of "reduction, harmlessness, recycling, reuse, and recycling" of waste materials. mode requirements. [0003] At present, the collection and cleaning process of waste mineral oil such as waste engine oil, industrial waste oil, ship berthing oil and residual oil is dirty, messy, poor and irregular. At the same time, the efficiency and thoroughness of the waste mineral oil recycling process need to be improved. Therefore, there is an urgent need to provide a waste mi...
