Form oily sludge, its source is that the water purification agent adding in the dirty water decontamination handles is formed during oil extraction
Flco, corrosion of device and piping product and various dirt thing, antibacterial (corpse) etc..Oil product storage tank store oil product when, in oil product
A small amount of mechanical admixture, the grains of sand, soil, heavy metal salt and the weight oily components such as paraffin and asphalitine are deposited on tank bottom,
Form tank bottom oil sludge.The composition of Sludge in Oilfields is extremely complex, typically miscellaneous by oil-in-water, Water-In-Oil and suspended solid
Matter forms, and is a kind of extremely stable suspension emulsion system, containing substantial amounts of aged crude oil, waxiness, asphalitine, colloid and solid
Body float, antibacterial, salt, sour gas, corrosion product etc., be also added in production process substantial amounts of flocculating agent, corrosion inhibiter,
The treatment agents such as antisludging agent, antibacterial.
The hydrocarbons contained by oily sludge producing in oil extraction in oil field and storage and transport process are larger to environmental hazard, belong to
Hazardous waste in " National Hazard waste register ".Now national each elephant has substantial amounts of oil-containing every year in process of production
Mud produces.One side oily sludge pollutes environment, and another aspect national environmental protection department starts to impose height to oily sludge discharge
No matter the charges for disposing pollutants of volume, so consider or the economic interests consideration from enterprise, the improvement of oily sludge is all from environmental conservation
Become the task of top priority.The measure of the process mud that each oil field is taken at present is also not quite similar.Its processing method is broadly divided into:
1. physical chemistry is processed: advantage is to make crude oil recovery, but needs extremely complex processing meanss, need to add people's chemical agent,
Still there are sewage, waste sludge discharge, processing cost is higher；
2. biological treatment energy saving, without chemical agent, but long processing period；A lot of oily sludges can not be thorough by microorganism
Bottom is decomposed, and the pollution to subsoil water has potential danger；
3. burning disposal harmful organic substance is processed thoroughly, but needs complicated incinerator；Because water content is high, fuel value is low, need to add
Enter combustion-supporting fuel in a large number, have large quantity of exhaust gas to discharge；Waste gas purification apparatus investment is high, is suitable only for focusing on.
Content of the invention
The present invention is intended to provide a kind of can be by oily sludge efficient utilization high for various water content；Low cost realizes dirt on the spot
Mud " minimizing, resource, innoxious "；And various energy resources step demand can be met as renewable distributed energy.

Value synthetic gas.The purified device of synthetic gas being generated returns for the heating of pyrolytic gasification body of heater after purifying, unnecessary
Heat supply, generating or storage.The harmless slag of inertia is discharged by pyrolytic gasification furnace bottom.In pyrolytic gasification course of reaction, stove
It is filled with inert nitrogen gas n in vivo2, as explosive-proof protector gas.
Oily sludge pyrolytic gasification and gas cleaning plant include two groups of modules, and one of which module is pyrolysis gasification furnace,
Another group of module is synthetic air purifying apparatus.
Pyrolysis gasification furnace is divided into top heat drying storehouse and bottom pyrolytic gasification storehouse.The feed arrangement in heat drying storehouse contains one
Disintegrating machine.
The dividing plate spraying non-sticky heat insulating coat of nano ceramics in heat drying storehouse and pyrolytic gasification storehouse.Heat drying storehouse keeps temperature
150 ° of c of degree about, material stop 30 minutes；Pyrolytic gasification storehouse 500 ° of c of keeping temperature about, material stop 30 minutes.
When material enters heat drying storehouse, it is fractured into width 10mm noodles shape.
Pyrolytic gasification storehouse inner surface spraying effective catalyst, catalyst main component is nanoscale Multimetal oxide.
Pyrolysis gasification furnace outer surface and dryness storehouse and pyrolytic gasification storehouse dividing plate spraying inorganic heat insulating anti-flaming dope, its main component
For sodium silicate, silicon dioxide, its heat leakage rate is less than 8%.The gasification storehouse spraying inorganic high efficient catalyst of pyrolysis gasification furnace bottom,
Catalyst main component be nanoscale Multimetal oxide, the thorough decomposition gasification of Organic substance can be accelerated, and make chemical reaction to
Generate carbon monoxide and hydrogen direction tilts.
Synthetic air purifying apparatus include a set of air swirl dust arrester；A set of bag-type dust collector；A set of condensation
Device；A set of removing carbon dioxide device；A set of desulfurizing device and a set of dust let-off gear(stand).
Pyrolysis gasification furnace is uniformly distributed 520 air inlets, in order to air inlet.According to the temperature generating synthetic gas and each gas
Body partial pressure, adjusts oxygen feeding amount and noble gases inlet.
Compare existing equipment, advantages of the present invention has: (1) is suitable for high-moisture percentage low heat value oily sludge, oily sludge from
Heat, be dried to pyrolysis, gasification overall process quickly completes, whole process only needs 60 minutes.(2) good environmental protection, nitrogen oxides
Growing amount is extremely low.This pyrolysis gasification furnace pyrolysis temperature is middle temperature and uniformly, and reaction under anaerobic condition, fundamentally reduces
Harmful gass yield.(3) oily sludge minimizing, innoxious degree highest, non-scaling in body of heater, lime-ash discharge capacity is few.This
