Problems solved by technology

②Incineration: generally used as fuel directly, the exhaust gas of this treatment method contains a large amount of heavy metal oxides and polycyclic aromatic hydrocarbon oxides generated by incomplete combustion, which will cause serious air pollution
However, the residue produced by this method cannot be effectively treated, and it will also pollute the environment.

Embodiment Construction

[0019] The method for the harmless disposal of waste mineral oil by means of blast furnace injection is described in detail below in conjunction with the accompanying drawings:

[0020] As shown in the attached figure: Firstly, the waste mineral oil is classified and collected, and then the collected waste mineral oil is pretreated. According to the actual situation of the waste mineral oil, one or several methods of sedimentation, filtration and flocculation are used in combination. Pretreat the waste mineral oil; the pretreated waste mineral oil is sent to the blast furnace oil storage tank by tank truck or pipeline; the oil storage tank has a heating device to heat the waste mineral oil to 90-100 °C. When the blast furnace is blown, the oil delivery pump pumps the waste mineral oil out of the oil storage tank and pressurizes it. Before the waste mineral oil is pressurized, it is filtered again to ensure that the pipeline and nozzle will not be blocked. The pressurized waste...

Abstract

The invention relates to a method for harmlessness treatment of waste mineral oil by a blast furnace injection mode. Through collection, pretreatment, blowing, combustion, and residue treatment on waste mineral oil having no regeneration value, and comprehensive utilization and thoroughly harmlessness treatment of a waste mineral oil resource are realized.

Description

[0001] Technical field: [0002] The invention relates to the field of environmental protection, in particular to a method for harmless disposal of waste mineral oil by blast furnace injection. [0003] Background technique: [0004] Waste mineral oil is extracted and refined from petroleum, coal, and oil shale. During mining, processing and use, the original physical and chemical properties have been changed due to external factors, and the mineral oil cannot be used any longer. Waste mineral oil is a complex mixture of various substances, the main components of which are C15-C36 alkanes, polycyclic aromatic hydrocarbons (PAHs), olefins, benzene series, phenols, etc. Once it enters the external environment, it will cause serious environmental pollution. [0005] In addition to losing its original excellent working performance, waste mineral oil is usually exposed to high temperature for a long time, or is catalyzed and oxidized by impurities, and many substances that are seri...
