Description

A kind of oily sludge continuous processing technique and processing unit
Technical field
The invention belongs to solid waste organic matter process fields, particularly relate to a kind of oily sludge continuous processing work Skill and processing unit.
Background technology
Oily sludge is the crude oil or product oil, body refuse, the mixture of water by other organic pollutions, is that oil is opened Adopt, oily waste water treatment, refining, the accompanying input generated in process of manufacture.By its source, difference is divided into oil field mud, accumulating Greasy filth, three mud three categories of refinery, oily sludge is bulky, if not being pocessed directly discharging, not only occupies a large amount of arable lands, and And surrounding soil, water body, air will all be polluted, it is generated with foul gas, and to surrounding soil, water body, air It will all pollute,《National promotion law on cleaner production》With《Solid waste environmental pollution prevention and control method》In be also distinctly claimed it is necessary Harmless treatment is carried out to oily sludge,《Waste mineral oil recycles pollution control technology specification》It is required that oil content > 5% Oily sludge must be recycled,《Pollutant catabolic gene standard in agricultural sludge》(GB4284-84) also provided in The content of agricultural sludge mineral oil in fluid is controlled in below 3000mg/kg.Therefore innoxious, the recycling treatment of oily sludge have Highly important meaning.
At present, the method for processing oily sludge has both at home and abroad:Burning method, biological treatment, hot washing method, solvent extraction Method, pyrolysis method etc. although processing mode is varied, there is the drawbacks of respective, and burning method energy consumption is big, and can generate two Secondary pollution;Biological treatment can only handle the relatively low greasy filth of oil content, and the cycle is long;The oily sludge of hot washing method processing is not Thoroughly, treated, and residue still needs to carry out after-treatment;The organic solvent that solvent extraction uses is mostly toxic and volatile And processing is not thorough;Pyrolysis method consumes energy relatively low for burning, but still falls within highly energy-consuming, and the thermal cracking oil generated into Point complexity, can not rationally using and easily lead to secondary pollution, and for the oily sludge after simple dehydration need carry out desiccation at Reason.Due to it is various the shortcomings that cause oily sludge that can not be really achieved innoxious, recycling treatment.
Pyrolysis method is considered as the processing method of most prospect, because it can not only control the oil content of residue Less than 3 ‰, and curing process can be carried out to the heavy metal in oily sludge, reach leaching standard, realize harmless treatment, But it is still larger in the presence of processing energy consumption, and since the mineral oil component in greasy filth is volatile, be badly in need of finding a kind of suitable greasy filth Desiccation mode;The residual oil that thermal cracking generates is due to a series of technical barriers such as the secondary pollutions that can not utilize and generate.
The content of the invention
The present invention for technical barrier existing for above-mentioned pyrolysis processing provide a kind of oily sludge continuous processing technique and Processing unit.
The it is proposed of the present invention solves the drying and other treatment problem of oily sludge, and recycling obtains the light oil resource of high-quality, And the maximum minimizing of residue and the processing utilization of residual oil are realized while realizing that oily sludge pyrolysis residue is innoxious, And by the use of the combustion gas collected as the air supply source of external-heat gas burning pyrolysis furnace, the thermal energy rationally carried using pyrolysis residue, significantly Reduce energy consumption.

(2) residue that step (1) generates is sent to high temperature pyrolysis stove, and residue carries out hot tearing at horizontal section of pyrolysis oven first Solution, this section of temperature are 630 DEG C~680 DEG C, by adjust the propeller rotating speed inside pyrolysis furnace control the residence time 25~ 35min。
(3) high temperature pyrolysis gas and residue generated in horizontal section of step (2) are split together into the vertical catalysis being connected to Section is solved, the temperature of catalytic pyrolysis section is controlled at 850 DEG C~950 DEG C, and heavy metal is converted into stable residue at high temperature in residue State, the carbon residue in residue are reacted with the vapor being passed through, make to generate more combustion gas while residue maximum minimizing, upper Heavy oil cracking is gaseous hydrocarbon, hydrogen and carbon monoxide as catalyst by residue while stating reaction, which controls In 15min~25min.
(4) residue generated in the vertical catalytic pyrolysis section of step (3) delivers heat to conduction oil by heat exchanger and supplies Cryogenic distillation reuse, the combustion gas of generation listen supercooling to burn after drying into pyrolysis oven combustion system, are pyrolysis oven Thermal energy is provided.
(5) residual oil content of treated residue reaches the standard less than 3 ‰, heavy metal indices in the maceration extract of residue In standard, the Residual carbon of residue is less than 4%.
The treatment process not only realizes maximum minimizing, the harmless treatment to oily sludge;Simultaneously in drying and distilling rank Section is recovered to the lightweight oil ingredient of high-quality, and pyrolysis phase recycles the thermal energy of residue, and the acquisition of catalytic pyrolysis residual oil largely may be used Combustion gas, the combustion gas supplying heat source as pyrolysis oven again, greatly reduces energy consumption, realizes the maximum resource of processing.
