Embodiment Construction
[0022] The present invention will be further described below in conjunction with accompanying drawing.
[0023] Such as figure 1 As shown, a device that uses microwave and plasma technology to further treat oil sludge. The present invention adopts a two-stage composite structure, which are microwave section (II) and plasma gasification section (III), and the upper end of the microwave section is connected to the feed section ( Ⅰ) are connected, the lower end of the plasma gasification section is connected with the ash collection section (IV), the lower end of the microwave section is connected with the upper end of the plasma gasification section, and the gas outlet (5) is set under the plasma gasification section, and the ash and slag Above the collection section, the gaseous product is sucked out by a suction pump. The side wall of the feeding section is provided with a feeding port and an air inlet (2), and the feeding port is externally connected to the feeding system (1)...

The invention discloses a device of deeply treating oil sludge by a microwave and plasma technique. The device disclosed by the invention is a two-section compound structure: a microwave section and a plasma gasifying section. The upper end of the microwave section is connected with the feeding section, the lower end of the plasma gasifying section is connected with an ash collecting section, the lower end of the microwave section is connected with the upper end of the plasma gasifying section, the gas outlet is arranged below the plasma gasifying section and above the ash collecting section, and a gas product is extracted by a suction pump. A microwave generator is arranged on the inner side wall of the microwave section for heating, evaporating and cracking moisture and light components in the oil sludge. Plasma guns are symmetrically arranged on the inner side wall of the plasma gasifying section for gasifying slags and heavy components which are incomplete in reaction by the microwave section to obtain more combustible clean gases. The device disclosed by the invention can improve the problems of waste of petroleum resources and secondary pollution and the like caused by conventional oil sludge treatment methods. The energy loss is reduced while oil sludge is deeply treated.
Description
technical field [0001] The invention belongs to the field of environmental science and technology and the field of petrochemical industry, and relates to a treatment for oily sludge, in particular to a device for deepening treatment of oily sludge by using microwave and plasma technology, which can effectively realize the harmless and resourceful treatment of oily sludge. Background technique [0002] Oil sludge is produced in the process of crude oil extraction, gathering and transportation, refining and refinery sewage treatment. In addition to a large amount of residual oil, it also contains benzene series, phenols, anthracene, pyrene and other foul-smelling toxic substances. Pathogens, heavy metals, salts, polychlorinated biphenyls, dioxins and other toxic and harmful substances. Therefore, oil sludge has been listed as non-mineral oil in the National List of Hazardous Wastes. In addition, oil sludge also has the characteristics of high viscosity, poor fluidity, and dif...
