Machine oil cleaning treatment system and technology

Abstract

The invention discloses a machine oil cleaning treatment system. The system comprises a mixing chemical dosing tank, a plate-frame filter press, an oil-water separator and an electric heating evaporator. A feed delivery pipe is arranged between the output end of the mixing chemical dosing tank and the input end of the plate-frame filter press, one end of the plate-frame filter press is equipped with a first oil drainage port, the bottom of the first oil drainage port is equipped with a first water outlet, and one side of the plate-frame filter press is equipped with a first water pump. By using an organic precipitant and an inorganic adsorbent, waste machine oil and water are subjected to mixed precipitation for adsorption of organic or inorganic colored impurities and metal ions, throughpretreatment of the plate-frame filter press, a clarified oil-water mixed solution can be obtained, and after the oil-water mixed solution passes through the oil-water separator, semi-finished productoil with low water content can be obtained, and through high temperature distillation, finished product crude oil can be obtained, and then by means of an oil filter, pure machine oil meeting the requirements can be obtained. According to the invention, waste machine oil is recycled, the process is simple and feasible, the operation is convenient, and the floor area is small.

Description

technical field [0001] The invention relates to the technical field of waste engine oil recovery and treatment, in particular to a cleaning engine oil treatment system and process. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to their health, and the national environmental protection department has further raised the emission standards of various substances, which makes some traditional recycling industries have to reshuffle, and the recycling of waste engine oil Also put on the agenda. In the past, waste engine oil was treated as fuel, which not only did not comply with the national environmental protection policy of energy conservation and emission reduction, but also caused secondary pollution after combustion, making it more difficult to handle. In addition, the traditional regeneration of waste engine oil required precipitation, distillation, pickling, Alkali neutralization, water washing, white cla...

Problems solved by technology

In the past, waste engine oil was treated as fuel, which not only did not comply with the national environmental protection policy of energy conservation and emission reduction, but also caused secondary pollution after combustion, making it more difficult to handle. In addition, the traditional regeneration of waste engine oil required precipitation, distillation, pickling, Alkali neutralization, water washing, white clay adsorption, and filtration are seven complicated processes, which not only waste a lot of manpower and material resources, but also make the residue after pickling and alkali neutralization more difficult to handle, which does not meet the current national energy conservation, emission reduction, and resource recycling.
