Waste oil treatment reaction system

Abstract

The invention discloses a waste oil treatment reaction system. The waste oil treatment reaction system comprises an air compression device, a nitrogen-making device, a high pressure nitrogen storage tank and a pneumatic reaction tank, wherein an additive feeding opening and an exhaust opening are formed in the top of the pneumatic reaction tank, an oil inlet and an oil outlet are formed in the bottom of the pneumatic reaction tank, a waste oil treatment zone is arranged in the pneumatic reaction tank and is one third to two thirds of the inner space of the tank from bottom to top, an air blowpipe is further arranged in the pneumatic reaction tank, one end of the air blowpipe extends into the waste oil treatment zone, and the other end of the air blowpipe extends out of the pneumatic reaction tank and is communicated with the high pressure nitrogen storage tank through a nitrogen conveying pipeline; an air guide disc is arranged at one end of the air blowpipe, which extends to the waste oil treatment zone; the diameter of the air guide disc is less than the inner diameter of the pneumatic reaction tank; a plurality of air outlets are formed in the bottom surface of the air guide disc, and the different air outlets are communicated with one another through channels in the air guide disc and are connected to the air blowpipe through a central channel in the top surface of the air guide disc. According to the waste oil treatment reaction system, the full mixing of waste oil and additives is realized by cooperation of nitrogen and pneumatic devices.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a waste oil treatment reaction system. Background technique [0002] Waste oil from refineries, oil fields or chemical plants has high viscosity, many impurities, solidifies and is not easy to flow, which makes it economical. In addition to additives, these waste oils may also contain metals produced by mechanical transmission wear and unburned fuel. Aromatic hydrocarbons, particulates, and water. In my country, waste oil is listed as a dangerous substance. After recovery, these waste oils are used as recovery fuel oils that meet the standards. They are burned in large coal or oil-fired power stations and liquid-supply boilers. The combustion of oil contains metal pollutants, carbon dioxide, carbon monoxide and sulfur dioxide, etc. These typical pollutants will cause huge pollution to the environment. [0003] To process these waste oils, some additives need to be put into the re...

AI Technical Summary

Problems solved by technology

[0004] 1) When exposed to the air, stirring will accelerate the oxidation of waste oil and its impurities, which is not conducive to the subsequent reaction treatment;

[0005] 2) Due to the high oil viscosity of waste oil, solidification and difficult flow, it will cause difficulty in stirring. If the stirring power is increased, the cost investment will be large. At the same time, it is difficult to fully mix additives and waste oil in mechanically stirred waste oil;

[0006] 3) Mechanical stirring is prone to friction and generate static electricity. If you are not careful, the reaction tank will explode, which will bring danger to life and property
