The every other embodiment obtained, belongs to the protection scope of the utility model.
The utility model embodiment is described in further detail below in conjunction with attached drawing.
As shown in Figures 1 and 2, a kind of continous way catalytic pyrolysis liquefaction machine, for urging the material of polybag containing greasy dirt
Change pyrolysis, material here refers to polybag containing greasy dirt.Device includes: kiln 2, catalytic reforming fixed bed 5, condenser pipe
8 with oil tank 9.
2 lateral inclination of the kiln arrangement, import are higher than outlet, are connected to feed inlet 1 above import；Outlet lower section
It is connected to slag-drip opening 4；Screw propulsion mechanism 10 is set in the kiln 2, it is continuous by import for pushing plastic bag containing greasy dirt
It is moved to outlet；Guarantee being carried out continuously for pyrolytic process.
The outlet of the kiln 2 connects catalytic reforming fixed bed 5, and usually there are two types of modes, and one kind is such as Fig. 1 institute
Show, the outlet of the kiln 2 connects 5 lower section entrance of catalytic reforming fixed bed by pipeline upwards, and described urges
Change and reforms 5 outlet condenser pipe 8 of fixed bed.Another way, as illustrated in the drawings, catalytic reforming fixed bed 5 are directly arranged in institute
The exit for the kiln 2 stated, without separately adding pipeline, the direct-connected catalytic reforming fixed bed 5 of kiln 2, catalytic reforming is fixed
5 outlet of bed is connected to condenser pipe 8 again.Connection condenser pipe 8 can be direct-connected or passes through pipeline.
This partial structure is for being pyrolyzed material by kiln 2.
The air in furnace is discharged firstly, being passed through nitrogen into kiln 2 for the process of pyrolysis, specifically to kiln
2 air inlet is passed through nitrogen, and flow is greater than 1L/min, and the duration is greater than 30 minutes, guarantees to form inert atmosphere in kiln.
Purpose is that the presence of oxygen is avoided to make the material in furnace that combustion reaction occur, causes temperature excessively high and oil product yield is reduced.
The kiln 2 can be equipped with air inlet.Feed inlet such as can be used without air inlet to replace.
Secondly, keeping normal pressure by 3 heating rotary kiln 2 of external heater by in-furnace temperature to 500 DEG C -700 DEG C.Tool
Temperature can according to be adjusted using raw material；The heating method of heating rotary kiln 2 is using rotary external heating.It can
So that kiln 2 is heated evenly and continuous.Hot wind after specifically being burnt with transporting combustible gases carries out external heating.Reaction
Initial stage can be using ordinary combustion gas (methane or CO etc.) as heat source.After raw material is begun to warm up, after reaction carries out a period of time,
Heat needed for the heat source that the tail gas of outlet can be used as burning provides pyrolysis.As shown in Fig. 2, the outer hot fume after burning passes through
Outer hot fume entrance enters external heater 3 and heats to rotary kiln, and the outer hot fume after heat exchange is discharged by outlet, realizes
The effective use of resource and zero emission.
Then, material is continuously added to by the feed inlet 1 of kiln 2, material is not necessarily to pre-treatment, is sent directly into feed inlet
1.Charging rate is adjusted according to actual condition, is carried out continuously the pyrolysis of material.Made by screw propulsion mechanism 10
Material is constantly elapsed and is reacted forward in pyrolytic process, i.e., pyrolytic reaction occurs containing material, guarantees material in kiln 2
Residence time is no less than 30 minutes；Specifically, by the push plate in kiln 2 make material in pyrolytic process constantly forward
(under) elapse and react.
Volatile matter after pyrolysis enters catalytic reforming fixed bed 5, and pyrolysis residue (lime-ash) passes through the slag-drip opening of kiln 2
4 continuous discharges；Specifically, polybag containing greasy dirt can occur pyrolytic reaction and be decomposed into escaping gas during pushing material
(volatile matter, also referred to as pyrolysis gas) and solid residue (lime-ash).The escaping gas (volatile matter) of high temperature is from 2 tail of kiln
The channel in portion enters catalytic reforming fixed bed 5, and kiln 2 is continuously discharged by slag-drip opening 4 in solid residue.
Catalyst 6 is set inside the catalytic reforming fixed bed 5；It is arranged outside the catalytic reforming fixed bed 5 solid
Fixed bed heating mantle 7；The 5 top discharge outlet of catalytic reforming fixed bed passes through 8 upper end of pipeline connection condenser pipe；The condensation
8 lower end of pipe passes through pipeline connection oil tank 9；This partial structure is used for catalytic reforming of the volatile matter in catalytic reforming fixed bed 5.
Specifically, the temperature of the bed of catalytic reforming fixed bed 5 is controlled at 350 DEG C -450 DEG C, with specific reference to required oil product
It is required that being adjusted.In general, temperature is higher, and oil quality improves but yield declines.Add especially by external fixed bed
Hot jacket 7 realizes temperature control.Catalyst 6 is set in catalytic reforming fixed bed 5, volatile matter passes through condensation after the effect of catalyst 6
Pipe 8 is condensed into the oil product of liquid, is collected by oil tank 9；The condensed tail gas of volatile matter is connected to and as external heater 3
Heat source use.
The catalyst uses HY molecular sieve catalyst, and more common catalyst of cracking petroleum ZSM-5, HY molecular sieve is urged
Agent is higher on the yield of fluid oil.
Outside the condenser pipe 8 by the way of water cooling.By the escaping gas (also referred to as exit gas) of catalyst 6
Then by condenser pipe 8, it is condensed into the oil product of liquid.Outside condenser pipe 8 by the way of water cooling, make the temperature of condensator outlet
Not higher than 100 DEG C.The fluid oil of condensation is collected by collector, and collector lower part is equipped with valve, can make to be collected into
Fluid oil, which is continuously transferred in other tanks, to be stored and is transported.
On-condensible gas i.e. tail gas, tail gas are mainly the alkane and alkene of some short chains, belong to fuel gas.Tail gas is logical
The gas piping for crossing bypass is delivered to the outside of kiln 2, as the heat source that kiln 2 heats, while having also eliminated
The discharge of evil gas.
Compared with traditional pyrolysis way, this technique has stronger specific aim for the processing of polybag containing greasy dirt.Firstly, adopting
Pyrolytic process handles polybag containing greasy dirt not only, also gets utilization, and obtains liquid fuel.Its
Secondary, the continuous feed of rotary kiln ensure that advantage of the technique in treating capacity and efficiency；Finally, passing through the HY molecule in fixed bed
The catalytic reforming of sieve not only makes the liquid fuel quality obtained higher, and yield is higher, and also avoids catalyst and raw material
It directly contacts, extends the service life of catalyst.The Treatment and recovery that whole set process realizes waste utilizes, and without dirt
Dye object generates again, belongs to clean energy-saving technology.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should
Subject to the scope of protection of the claims.
