High-efficiency tower type waste oil processing system

Abstract

The invention discloses a high-efficiency tower type waste oil processing system, and belongs to the field of petrochemical industry. The system comprises a waste oil preprocessing module, a tower type distillation module, a cooling module I, a collecting module I, a vacuum module I and a tail gas processing module I which are sequentially connected, a collecting module II is positioned between the cooling module I and the vacuum module I and is parallel to the collecting module I, the tower type distillation module is composed of a fuel oil distillation module and a base oil distillation module which are arranged in parallel behind the waste oil preprocessing module, the fuel oil distillation module is respectively connected with the cooling module I and the base oil distillation module, and a cooling module II, a collecting module III, a vacuum module II and a tail gas treatment module II are sequentially connected behind the base oil distillation module. The system has the characteristics of realization of closed loop treatment of waste oil, good sealing property, long life, high running safety, reduction of air pollution discharge, and energy saving, and processed fuel oil and base oil accord with national quality standards.

Description

technical field [0001] The invention belongs to the technical field of petrochemical industry, and relates to a high-efficiency tower-type waste oil treatment system. Background technique [0002] With the rapid development of economy and society, large-scale machinery industries such as automobiles, ships, airplanes, and trains have developed rapidly, and at the same time, industrial waste oils (including additives, metal abrasive particles, and unburned fuels) have been produced in large quantities. In my country, these industrial waste oils are recovered as standard recovery fuels and burned in large thermal power stations. Because waste oil contains a large amount of metal pollutants, carbon compounds and sulfur compounds, it will cause huge environmental pollution after combustion. Therefore, waste oil treatment is of great significance, namely saving energy and turning waste into treasure, which is conducive to the full utilization of oil resources, and can prevent en...

Problems solved by technology

In the process of using the oil circulation vacuum pump alone, the circulation medium of the oil circulation vacuum pump is easily polluted by the water vapor in the waste oil vapor, resulting in a reduction in the working efficiency and service life of the oil circulation vacuum pump

In the process of using the water circulation vacuum pump alone, the vacuum degree of the entire equipment cannot meet the requirements, and the distillation temperature of the distillation equipment needs to be increased, resulting in an increase in the amount of heating fuel required and an increase in distillation costs

[0006] 3) The tail gas is directly discharged into the atmosphere without treatment, which cannot make full use of energy
