Description
Technical field
The invention belongs to field of environment engineering, and in particular to a kind of thermal energy recycling system of the low-temperature plasma of petrochemical sludge
System.
Background technique
Dross, the biochemistry pool that chemical plant, the oil plant greasy filth that oil separator generates in sewage disposal process, floation tank generate
It is simple that the residual active sludge and sewage of generation adjust the tank bottom oil sludge that the structures such as tank, slop tank and flocculation sedimentation tank generate
Referred to as three mud.Three mud belong to petrochemical sludge, due to wherein containing oil, phenol, COD, sulfide and other pollutants etc., no
Environment can be directly discharged into.Petrochemical sludge is easily smelly in heavy pond, and moisture content is high, it is more difficult to be dehydrated, be at petrochemical sludge
The main object of reason.
Foreign countries for petrochemical sludge processing method in last century the eighties before be also all almost based on landfill, not
End disposition is carried out, the eighties start to put into effect relevant laws and regulations, later until the nineties are just executed gradually for petrochemical industry
It disposes the end of sludge.Mainly have for the method for disposal of petrochemical sludge both at home and abroad at present: being burned after separation, modulation, dehydration；Heat
Desorption, including the high-temperature process and Low Temperature Thermal chemical conversion to oily sludge；Solvent extraction treatment process；Sludge wet type air oxygen
Change；The biological treatment of sludge；Raw material or chilling liquid as coking plant are recycled；As catalytic cracking unit fractionating column
Slurry oil recycled；Sludge fuel, including sludge anaerobic fermentation methane production, heat supply power generation, are dehydrated synthetic fuel.It burns
The outstanding feature of method is: the volume and weight of sludge can be greatly decreased；All pathogen are killed, Treatment of Sludge speed is fast, is not required to
Want long term storage；Sludge can on-site incineration, do not need long-distance transportation；It can recover energy for power generation and heat supply etc..Thus
Incineration method is petrochemical sludge processing method of disposal popular at present at home.But incineration method consumption is very big, flue gas row
High-volume big, more crucial is some the recycling being not carried out to oily residuum thermal energy, causes the waste of resource.
Plasma is the 4th kind of state of matter different from these three states of matter of solid, liquid, gas, wherein containing ion,
Electronics, excited atom and molecule, free radical etc..Plasma technique is the research hotspot in environment in recent years pollution field, is obtained
Extensive concern is arrived, and as a kind of high-level oxidation technology, the central principle of plasma technique is produced using electrion
Raw living radical (O, H, OH etc.) and strong oxidizing property molecule (O3、H2O2Deng).With conventional incineration it is entirely different etc.
Ion gasification technology, due to its high temperature and high heat density, plasma gasification technology almost can be complete by the organic matter in carbon-based waste
It is converted to synthesis gas (predominantly CO and H entirely2, can recycle as the energy), and inorganic matter then becomes harmless lime-ash (glass
Body).For the industrial refuse and harmful waste in processing solid waste, plasma gasification technology has engineering in foreign countries and answers
With.Using plasma gasification technical treatment petrochemical sludge, minimizing and innoxious effect can not only be played, while being more able to achieve
The purpose of recycling, though converting the energy for petrochemical sludge using plasma technology is new process, it has very big potentiality,
Compared with other heat treatment modes, plasma technology can more effectively be run, have the advantages that more cleaning, it is more stable.In consideration of it, this
Invention proposes a kind of heat reclaiming system of the low-temperature plasma of petrochemical sludge.
