Abstract
The invention discloses a granulating incineration method of oily sludge, comprising the following steps of: (1) feeding the oily sludge which accounts for 20-80 percent of the total weight and clay which accounts for 80-20 percent of the total weight into a mixing agitator to fully agitate and mix; (2) ageing the mixed material; (3) feeding the aged material into a mud mixer and extruding mud pieces by the mud mixer; (4) sequentially delivering the mud pieces extruded from the mud mixer into a granule extruding machine and a granulator for granulation, and sending the undersize material from the granulator back to the mud mixer; and (5) delivering the oversize material from the granulator into a rotary kiln to roast, and taking out to obtain porcelain granules, wherein the temperature of the rotary kiln is controlled to 1000-1200 DEG C, and coal dust is used as a fuel by the rotary kiln. The granulating incineration method has the advantages of large processing capacity and low energy consumption, and particularly enables a traditional incinerator using electricity and oil to be substituted by the rotary kiln using the coal dust as the fuel, thereby the operation cost of incineration is greatly reduced, and an incinerated product can be used as the raw material of a light-weight building material.
Description
Technical field
The present invention relates to a kind of incinerating method, particularly the granulation incinerating method of oily sludge.
Background technology
Oily sludge is the oil-containing solids refuse that produces in oil exploitation, transportation, refining and oily waste water treatment process.General oil content is 10～50% in the mud, moisture content is 40～90%, in the China's oil chemistry industry, produce 800,000 t jar bed muds, pond bed mud every year on average, the annual oily sludge that produces of Shengli Oil Field is more than 100,000 tons, annual about 150,000 tons of the oily sludge that produces of Dagang Oilfield, Henan Oil Field is annual to produce 5 * 10
4m
3Oily sludge.Contain cacodorous noxious materials such as a large amount of benzene series things, phenols, anthracene, pyrene in the oily sludge, oily sludge is if handled, contaminated environment not only, and cause the waste of resource.The processing of oily sludge is a great problem in puzzlement oil field always.
Oily sludge is bulky, if do not handled directly discharging, not only take a large amount of arable lands, and all will pollute surrounding soil, water body, air, produce with foul gas, and all will pollute, produce with foul gas to surrounding soil, water body, air, mud contains heavy metals such as a large amount of pathogens, parasite (ovum), copper, zinc, chromium, mercury, the poisonous and harmful substance of difficult degradations such as salt and Polychlorinated biphenyls, dioxin, radionuclide.
It is with minimizing, resource, the harmless principle that turns to that oily sludge is handled final purpose.The processing method that oily sludge is commonly used: solvent extraction, burning method, bioanalysis, pyrogenic process, oily sludge profile control, oily sludge comprehensive utilization etc.Wherein the burning disposal of oily sludge is the most general method of using now.It is little that but present incinerating method exists treating capacity, shortcomings such as energy consumption height.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide a kind for the treatment of capacity big, energy consumption is low, greatly reduces the granulation incinerating method of oily sludge of the operating cost of burning.
In order to achieve the above object, the technical solution used in the present invention is:
The granulation incinerating method of oily sludge, it may further comprise the steps:
(1) will account for the oily sludge of gross weight 20%--80% by weight percentage, the clay that accounts for gross weight 80-20% is sent in the mixing agitator and is fully mixed;
(2) with mixed material ageing;
(3) material after the ageing is sent into tug mill, tug mill is extruded slice;
(4) slice that tug mill is extruded is delivered to successively and is squeezed grain machine and comminutor granulation, and the screenings of described comminutor returns to tug mill;
(5) oversize of comminutor is sent into the rotary kiln roast and is taken out after 50-60 minute and make haydite, and described kiln temperature control is at 1000-1200 ℃, and rotary kiln uses coal dust to act as a fuel.
The invention has the advantages that: treating capacity is big, energy consumption is low, especially with traditional electricity consumption, with oil incinerator be transformed into the rotary kiln that acts as a fuel with coal dust, greatly reduce the operating cost of burning, simultaneously, incineration ashes can also be as the light building material raw material.
Description of drawings
Accompanying drawing is the schematic flow sheet of the granulation incinerating method of oily sludge of the present invention.
The specific embodiment
Describe the present invention below in conjunction with specific embodiment.
The granulation incinerating method of oily sludge of the present invention is characterized in that it may further comprise the steps: (1) will account for the oily sludge of gross weight 20%--80% by weight percentage, and the clay that accounts for gross weight 80-20% is sent in the mixing agitator and fully mixed; If the mixture content of oily sludge surpasses 80%, then mix the too high granulation performance of material that causes easily of back material oil content and reduce the broken easily burning process that influences.The oil content of oily sludge is 6%-15% by weight percentage, and the granulation effect is best in this scope, and is most effective, is higher than this scope and then is unfavorable for granulation.(2) with mixed material ageing, digestion time is preferred for 7-14 days, can make like this that oil content fully disperses in the material, homogenize, improves granulation performance; (3) material after the described ageing is sent into tug mill, tug mill is extruded slice; (4) slice that described tug mill is extruded is delivered to successively and is squeezed grain machine and comminutor granulation, and the screenings of described comminutor returns to tug mill; (5) oversize of comminutor is sent into the rotary kiln roast and is taken out after 50-60 minute and make haydite, and described kiln temperature control is at 1000-1200 ℃, and rotary kiln uses coal dust to act as a fuel.Rotary kiln length can be 20-30 rice, and the exhaust temperature that rotary kiln is discharged is controlled at 200-240 ℃ usually.The rotary kiln flue gas reaches the discharge standard requirement through general dedusting, purifying processing device.
Accompanying drawing is the device of the granulation incinerating method of realization oily sludge of the present invention; it comprises batch mixer, tug mill, crowded grain machine and the comminutor that links to each other successively; the screenings output of described comminutor links to each other with the charging aperture of tug mill by first conveying device, and the oversize output of described comminutor links to each other with the feeding mouth of rotary kiln by second conveying device.
