Embodiment 1

[0015] Embodiment one: if Figure 1-2 As shown, in this embodiment, the microwave harmless treatment system for oily sludge includes a vertical rotary microwave pyrolysis furnace 4, a condenser 6 and an oil-water separator 8, and the vertical rotary microwave pyrolysis furnace 4 includes a shell 9. The supporting legs 15 of the housing 9, the screw feeding distributor 10 arranged on the upper side of the housing 9, the rotating cone 13 arranged at the center of the housing 9, the rotating cone 13 arranged at the lower part of the inner wall of the housing 9 The scraper 11 between them, the jacketed slag hopper 12 arranged under the scraper 11, and several microwave breaches 16 arranged in the circumferential direction of the upper part of the shell 9, the microwave breaches 16 are fixedly connected with a microwave generating source 17 , one end of the screw feeding distributor 10 extends to the outside of the housing 9, the other end of the screw feeding distributor 10 exten...

Embodiment 2

[0017] Embodiment 2: This embodiment is basically the same as Embodiment 1, except that the outer walls of the vertical rotary microwave pyrolysis furnace 4 , the connecting pipe 5 and the condenser 6 are all provided with insulation layers.

Embodiment 3

[0018] Embodiment 3: This embodiment is basically the same as Embodiment 1, except that the microwave breaches 16 are evenly distributed in the circumferential direction of the upper part of the casing 9 .

[0019] The oily sludge microwave harmless treatment system processes oily sludge as follows:

[0020] The oily sludge enters the vertical rotary microwave pyrolysis furnace 4 through the hopper 1 and the screw feeding distributor 10, and the material in the furnace is driven by the rotating cone 13 to rotate, and the newly entered oily sludge is evenly distributed on the top of the furnace material , under the action of the microwave energy emitted by the microwave generating source 17, the temperature is gradually raised and dried, and finally reaches the temperature required for heavy oil cracking. Separation and recovery in the middle, the non-condensable gas is pumped away through the air pumping system 7 as fuel, the remaining slag after pyrolysis is scraped into the ...

Abstract

The invention discloses a microwave harmless treatment system for oily sludge, which comprises a vertical rotary microwave pyrolysis furnace, and the vertical rotary microwave pyrolysis furnace includes a shell, supporting legs, and a spiral feeding distributor arranged on the side of the shell , the rotating cone set in the center of the shell, the scraper plate set between the lower part of the inner wall of the shell and the rotating cone, the slag hopper set under the scraper plate, a number of microwave breakouts and fixing holes set in the upper ring of the shell On the microwave generating source on it, one end of the screw feeding distributor extends to the outside of the shell and connects to the silo, and the other end extends above the center of the rotating cone. The rotating cone is connected with a power mechanism that drives its rotation. The gas outlet and the volatile gas outlet are connected to the condenser inlet through connecting pipes, the upper outlet of the condenser is connected to the extraction system, and the lower outlet of the condenser is connected to the oil-water separator. The invention has the advantages of compact structure, high efficiency, continuous and rapid feeding, material distribution and slag discharge, and reliable operation.

Description

technical field [0001] The invention relates to a treatment system for oily sludge, in particular to a microwave harmless treatment system for oily sludge. Background technique [0002] Oily sludge mainly comes from petroleum exploration, refining and petrochemical industries. With the increase of oil production, the total amount of oily sludge produced is also increasing, and the pollution to the environment is becoming more and more serious. Therefore, whether it is from the perspective of environmental protection, maintenance of normal production or energy recovery, it is necessary to carry out harmless and resourceful treatment of oily sludge. [0003] Oily sludge is heated by microwave under anaerobic conditions and treated with thermal cracking technology, which is to improve the recovery rate of oil and gas resources in oily sludge, reduce environmental pollution, and improve economic benefits. One of the important ways of mud treatment. However, the microwave treat...
