Abstract
The present invention relates to a method for treating oil sludge and sewage generated in oil refinement from oil shale. The present invention is mainly characterized in that the oil sludge of dry distillation, sewage and the oil sludge of oil shale are added to a heating device according to a certain proportion to be mechanically stirred and mixed; the mixture is conveyed to a combustion device in a thermal state for combustion, and the air pressure in a pipeline during combustion in the combustion device is from 4.5 to 5.0 kg/cm<2>; the gas flow jet speed of an atomizer is from 300 to 320 meters per second, and the slurry jet speed of the atomizer is from 1.5 to 2.0 meters per second. After treatment by the combustion method, the discharged white smoke conforms to the discharge standard of environmental protection.
Description
The invention belongs to organic sewage, technical field of sludge treatment, is a kind of to the greasy filth that bituminous shale oil refining produced and the method for sewage disposal.
In retort process, produce destructive distillation greasy filth and retort sewage with bituminous shale oil refining.These two kinds of material composition complexity, organic content is many, and discharging after stain environment is serious.In known technology, United States Patent (USP) discloses a kind of mud slurry burn processing method for No. 4599954, and this method is that the mud slurry is mixed, grinds with the particulate matter with certain calorific value (for example coal), and through certain processing afterfire; Also disclose a kind ofly with coal dust in the T104901 document of the U.S., organic waste materials and water slurry mix, and send into the treatment process that incinerator goes by slush pump.Though above-mentioned two files have proposed the burn processing method to sewage, mud, do not relate to oil shale retorting sewage smeary burn processing technical problem as yet.
The objective of the invention is to solve at present still can not be to oil shale in retort process, the problem that generation destructive distillation greasy filth, retort sewage are handled, provide and a kind of destructive distillation greasy filth, sewage are mixed with mechanical stirring in heating unit according to a certain ratio with oil shale greasy filth, and under hot state, be transported in the combustion unit and burn, thereby finish to greasy filth the treatment process of sewage.
Accompanying drawing 1 is a pulping device;
Accompanying drawing 2 is firing system synoptic diagram.
Among Fig. 1: 1 is agitator, can be propeller agitator, and 2 is pulping tank, and 3 is external bushing, and 4 is steam inlet, and 5 is vapour outlet, and 6 is ball valve, and 7 is the curved bar pump.
Provide below the material that mud processed is used and the proportioning:
Retort sewage is: 25%;
Destructive distillation greasy filth is: 25%;
Be not more than 70 order granularity mud powder 50% after the oven dry of oil shale greasy filth.
Above-mentioned three kinds of materials are joined in the pulping device by the proportioning that provides, heat with steam inlet 4 input steam, temperature is 70-90 ℃ and stirs with agitator under hot state, rotating speed can be 150 rev/mins, stirs back mud and is transported in the combustion unit being not less than 70 ℃ of condition lower pipelines.
In Fig. 2: 8 be pulping device, 4 for steam inlet, 5 for vapour outlet, 7 for the curved bar pump, 10 for greasy filth slurry pipeline, 11 for igniting oil line, 12 atomizing air pipelines, 13 for spraying gun, 14 for air distributor, 9 for lighter for ignition, 15 for body of heater, 16 for pneumatic line, 17 is spark coil, 18 for the oil tank, 19 of lighting a fire be the retort sewage jar.
After mud is got by curved bar pump 7 by the road 10 by spraying gun 13 ejection.When mud was burnt by the spraying gun ejection, the steam flow spouting velocity in the air pressure in the pipeline 12, the spraying gun 13, mud speed and the angle data when spraying gun sprays provided as follows:
Air pressure in the pipeline 12 is: 4.5-5.0kg/cm
2
Air-flow spouting velocity in the spraying gun 13 is: the 300-320 meter per second
The mud spouting velocity is in the spraying gun 13: the 1.5-2.0 meter per second
The atomizing angle that mud is sprayed by spraying gun 13: β=75-80 °
Implementation process of the present invention is: lighter for ignition work, put kerosene ejection simultaneously, and slurry conveyed then, spraying gun 13 ejection mud speed can be used 1.6 meter per seconds, and the slurry atomization angle is 76 °, and the input air pressure of spraying gun 13 is 4.5kg/cm
2The air-flow spouting velocity of spraying gun is 30 meter per seconds.Material proportion is: sewage is 25%, greasy filth 25%, mud powder 50%.
After using this treatment process that destructive distillation greasy filth and retort sewage are made greasy filth slurry burn processing, through below 3000 millimeters places of chimney record data, providing:
Sulfurous gas SO
22.46 kilogram/hour
Oxynitride NO
x4.13 kilogram/hour
2.33 kilograms/hour of carbon monoxide CO
11.25 kilograms/hour of flue dust TXP
The cigarette that discharges be white, blackness is the 0-1 degree by Lin Geman, meets environmental emission standard, eliminates the pollution to environment of stench and carcinogenic substance.
Claims (1)
