Problems solved by technology
Waste engine oil is usually thrown away as waste. There are many kinds of oil in waste engine oil, which will cause waste of resources and environmental pollution. Waste engine oil can also be used as fuel, but waste engine oil contains various miscellaneous oils, water, dust and Iron filings, etc., so the combustion of waste engine oil produces less heat and produces a lot of smoke, polluting the environment and endangering human health

Embodiment Construction
[0019] The present invention will be further described below in conjunction with accompanying drawing:
[0020] The waste engine oil refining method of the present invention comprises the following steps,
[0021] A. Introduce the waste engine oil into the settling tank 1, heat it to 50°C-60°C and keep it warm for 48-60 hours;
[0022] B. The precipitated waste engine oil enters the heating pipe of the convection chamber 22 of the heating furnace 2 and is heated to 150°C-160°C, and then the waste engine oil is introduced into the dehydration tower 3 to separate the light components in the waste engine oil. Components include water and gasoline;
[0023] C. The waste engine oil at the bottom of the dehydration tower 3 is pumped into the heating tube of the radiation chamber 21 in the heating furnace 2 and heated to 360°C-380°C, and then the waste engine oil is introduced into the separation tank 4, and the heavy ungasified components are used as slag After the oil sinks, it i...

The invention discloses a waste engine oil refining method and refining equipment. The method comprises the following steps: introducing waste engine oil into a precipitation tank, heating to a temperature of 50 to 60 DEG C, maintaining the temperature for 48 to 60 hours to carry out precipitation; after precipitation, introducing the waste engine oil into the convection chamber of a heating furnace, heating the waste engine oil to a temperature of 150 to 160 DEG C, introducing the waste engine oil into a dehydration tower, carrying out distillation, collecting the light components of the waste engine oil; introducing the waste engine oil in the bottom of the dehydration tower into a radiation chamber, heating to a temperature of 360 to 380 DEG C, introducing waste engine oil into a separation tank, discharging the precipitated residual oil from the bottom of the separation tank; introducing the gasified part of waste engine oil into a fractionating tower, fractionating out diesel oil from the top of the fractionating tower, fractionating out lubricant basic oil from the middle siding of the fractionating tower, and fractionating out lubricating grease raw material from the bottom of the fractionating tower. The refining equipment comprises a precipitation tank, a heating furnace, a dehydration tower, a separation tank, and a fractionating tower. The provided method is capable of refining waste engine oil to obtain diesel oil, lubricant basic oil, and lubricating grease raw material, reduces the environmental pollution, and reutilizes the resources.
Description
technical field [0001] The invention belongs to the technical field of waste oil treatment, and in particular relates to a waste engine oil refining method and refining equipment. Background technique [0002] Waste engine oil refers to the waste lubricating oil replaced from various vehicles, ships, lathes and mechanical components. Waste engine oil includes diesel and gasoline for cleaning oil stains. Waste engine oil is usually thrown away as waste. There are many kinds of oil in waste engine oil, which will cause waste of resources and environmental pollution. Waste engine oil can also be used as fuel, but waste engine oil contains various miscellaneous oils, water, dust and Iron filings, etc., so the combustion of waste engine oil produces less heat, and produces a lot of smoke, which pollutes the environment and endangers human health. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the present invention provides a wa...
