Description
Technical field
The utility model belongs to environmental technology field, and in particular to a kind of greasy filth cracker.
Background technique
Greasy filth is the abbreviation of oily sludge, is generated during oil exploitation, transport, refining and oily waste water treatment
Oily solid sludge, general oil content is even higher in 10-50% in greasy filth, and moisture content is 30% or more, China's oil
In scholarship and moral conduct industry, 800,000 tons or more of oily sludge is generated every year on average, the processing of this partial sludge is that China's petrochemical field is long-term
Problem.The processing technique of oil sludge includes landfill, profile control injection stratum, curing process, thermal desorption, solvent extraction both at home and abroad at present
Take, burn coking pyrolysis, biological treatment, comprehensive utilization etc. more than ten.But above numerous methods are in practical large-scale industrial application
In there are treatment processes at high cost, complex process equipment, low efficiency, secondary pollution problems limit it and further use.It will be oily
It is a selection well that mud carries out processing by way of Pintsch process, but due to greasy filth have oil content is high, viscosity is big,
The features such as particle is thin, dehydration is difficult lacks corresponding effective greasy filth cracking apparatus in the prior art.
Summary of the invention
In response to the above problems, the present invention proposes a kind of greasy filth crackers, can be expanded using the utility model
Heat exchange area in greasy filth cracking process improves heat exchange efficiency, and then improves the rate of cleavage of greasy filth, realizes sufficiently splitting for greasy filth
Solution.
The specific technical solution of the utility model is: a kind of greasy filth cracker, including outer barrel and inner cylinder, inner cylinder
Inner wall is equipped with spiral conveyor, is provided with heat conducting pipe on helical feed band.
When specific works, greasy filth to be cracked enters the inner cylinder of cracker, to out under the action of spiral conveyor
Material mouth runs while being cracked.Inner cylinder inner wall is equipped with spiral conveyor, heat conducting pipe is provided on helical feed band, in spiral
With in the operational process for pushing material, when material and heat conducting pipe contact, heat conducting pipe can provide contact heat for material cracking；When
When material and heat conducting pipe do not contact, heat conducting pipe can provide radiant heat for material cracking.
Further, several heat conducting pipes are evenly arranged in each screw pitch of the spiral conveyor, it is preferably each
Three heat conducting pipes are evenly arranged in a screw pitch, heat conducting pipe is arranged along spiral conveyor rotation direction, can be provided for material to be cracked
More heats increase the heating surface area of material to be cracked.In addition, increasing material due to being made full use of to heat
Heating surface area, the utilization rate of heat greatly improves, and then reduces the cracking temperature of greasy filth to a certain extent.Cracking temperature
It reduces, avoids the generation of coking phenomenon, improve the service life of equipment.
Since greasy filth water content to be cracked is high, in thick, dispersion is equipped with solid in inner cylinder described in the utility model
State heat carrier.The solid-state heat carrier is metal ball body or nonmetallic sphere.Greasy filth to be cracked is mixed with solid-state heat carrier
After can uniformly be wrapped in solid state heat carrier surface, make greasy filth relative distribution, and increase the heating surface area of greasy filth, make it more
Add easy cracking.In addition, due to being equipped with solid-state heat carrier in inner cylinder, in cracking process, solid-state heat carrier and inner cylinder it
Between there are relative motions, play the role of certain coke cleaning, avoid the generation of coking phenomenon, improve the service life of equipment.
The sphere diameter is 5-50mm.
The heat conducting pipe is hollow tube, and heat source is from the hot wind between outer barrel and inner cylinder in hot air cavity.It leads
Heat pipe is connected to hot air cavity.With the movement of spiral conveyor, heat conducting pipe is also being moved, when heat conducting pipe is rotated to proper angle
When, hot wind enters heat conducting pipe, and when heat conducting pipe is rotated to other angles, hot wind comes out from heat conducting pipe, and then realizes and constantly change
Heat.
After above-mentioned cracking, greasy filth is cracked into high-temperature oil gas, vapor and solid product.High-temperature oil gas, vapor warp
After cooling, liquid product and a small amount of combustible gas are obtained.Liquid product is delivered to tank field by oil transfer pump.As combustion after combustible gas purifying
Material is for being pyrolyzed heat supply.The flue gas that production line generates, the qualified discharge after flue gas purification system purifies.Resulting solid is pyrolyzed to produce
Object is cooled to after safe temperature that be delivered to solid product feed bin temporary.
In conclusion expanding the heat exchange in greasy filth cracking process using greasy filth cracker described in the utility model
Area improves heat exchange efficiency, so that the utilization rate of heat greatly improves, improves the cracking speed of greasy filth at a lower temperature
Degree, has sufficiently recycled the petroleum in greasy filth, and the resid amount after processing in soil is made to be up to state standards rule, realizes greasy filth
Minimizing, innoxious, recycling processing and application do not generate secondary pollution, economic, environmental protection, safety.
