Detailed Description
The present invention will now be described in detail with reference to the drawings, which are provided for illustrative and explanatory purposes only and should not be construed as limiting the scope of the present invention in any way.
The utility model provides a continuous thermal cracking oil sludge treatment system, which comprises a molten salt tank 1, a gas molten salt furnace 2, an air preheater 3, an oil sludge processor unit 4, a scraper conveyor 5, an oil sludge tank 6, a cooling conveyor 7, a humidifier 8, a tailings pond 9, a cooling water tank 10, an oil storage tank 11, a spraying tank 12, a sedimentation tank 13, a water tank 14, a combustion chamber 15, a buffer tank 16, a water seal tank 17 and a self-absorption sewage pump 18;
the molten salt tank 1 is connected with the gas molten salt furnace 2 through a pipeline;
the oil sludge processor unit 4 is respectively connected with the molten salt tank 1, the gas molten salt furnace 2 and the air preheater 3 through pipelines;
the sludge processor unit 4 is respectively connected with the cooling water tank 10 and the oil storage tank 11 through pipelines;
the scraper conveyor 5 is connected with the sludge treater unit 4 through a pipeline;
the oil sludge tank 6 is connected with the oil sludge processor unit 4 through a pipeline;
the scraper conveyer 5 is connected with the cooling conveyer 7, the humidifier 8 and the tailing pond 9 through pipelines;
the cooling water tank 10 is connected with the oil storage tank 11 through a pipeline;
the oil storage tank 11 is respectively connected with the buffer tank 16 and the self-priming sewage pump 18 through pipelines;
the water tank 14 is respectively connected with the buffer tank 16 and the water seal tank 17 through pipelines.
The sedimentation tank 13 is respectively connected with the spraying tank 12 and the self-suction sewage pump 18 through pipelines.
The combustion chamber 15 is connected with a water seal tank 17 through a pipeline.
Oil-containing sludge enters a molten salt tank 1 through an oil sludge processor unit 4, molten salt enters a gas molten salt furnace 2, oil-water mixed steam and powder are formed after the oil-water mixed steam is heated by an air preheater 3, and the oil-water mixed steam enters a spraying tank 12 and a sedimentation tank 13.
The oil-water mixed steam entering the spraying tank 12 and the sedimentation tank 13 for treatment continues to enter the cooling water tank 10; and the tailings pass through a cooling conveyor 7 to a humidifier 8 through a scraper conveyor 5 and then enter a tailings pond.
The oil-water mixed steam is treated by the cooling water tank 10 to form oil-water mixed liquid which enters the oil storage tank 11.
After being treated by the oil storage tank 11, the non-condensable gas enters the combustion chamber 15 through the buffer tank 16 and the water seal tank 17, the oil-water mixed liquid passes through the buffer tank 16 and the water seal tank 17, the wastewater enters the water tank 14, and the oil enters the oil receiving tank.
Because the oily waste contains part of industrial waste and household waste, the oily waste cannot directly enter the continuous pyrolysis treatment equipment, the oily waste with larger particles is firstly pretreated by the vibrating screen, the oily waste with smaller particles is separated, and the separated oily waste with smaller particles enters the continuous heating device. The heating device uses the composite salt as a heat transfer medium, has the characteristics of high temperature (up to about 650 ℃), high thermal efficiency, stable thermal efficiency, accurate temperature control (+/-1 ℃), safety and reliability, and can effectively prolong the service life of the continuous heating device by using the composite salt as the heat transfer medium. After the oily waste is heated by the heating device, oil and water are changed into gas, the oil-water mixed steam firstly passes through the cyclone separator to remove solid particles included in the steam, so that the solid particles fall into the slag storage tank, then the oil-water mixed steam is condensed into liquid through the cooling water tank, the water and the oil enter the oil-water mixed tank, and the combustible gas which cannot be condensed enters the molten salt furnace through the pipeline again to be fully utilized as fuel. After the oil-water mixed liquid is separated by an oil-water separator, oil content enters an oil storage tank for recycling, and after the separated waste water reaches the standard, part of the separated waste water is used for humidifying and dedusting waste residues, and the other part of the separated waste water is used for supplementing water by a cooling water tank.
The waste drilling fluid can generate obvious sedimentation phenomenon when being static in the sewage tank, and the stability of feeding can be influenced when the water content of sludge entering the treatment equipment is changed greatly. Therefore, in the treatment process, the pollutants in the sewage tank are fully stirred in advance before feeding, so that the solid and the liquid are uniformly mixed, and the material properties are kept consistent.
When the equipment finds that the oil content of the treated waste residue exceeds the standard, the equipment can automatically adjust the pyrolysis temperature and the treatment speed so as to meet the requirement of the lowest oil content.
When the system fails and can not normally operate to process the drill cuttings, the automatic alarm system can be triggered, and when the system fails, the drill cuttings can be removed under the working state without shutdown.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
