Description
Technical field
The present invention relates to high molecular waste material processing technology fields, and in particular to a kind of oiling of high molecular waste material is set
It is standby.
Background technology
All the time, as the equipment that thermal decomposition recycling oil is carried out to high molecular waste material, generally as specification is attached
Equipment shown in Fig. 3.For the equipment in Fig. 3, pre-processing device 90 is first provided with, for the macromolecule as raw material to be discarded
Object PW is crushed to appropriate size (coarse crushing 90a, Crushing of Ultrafine 90b), removes the metal component being mixed in inside high molecular waste material
After (removing iron 90c), the pre-processing device of washing 90d, dry 90e are carried out.
Then, the high molecular waste material PW that pre-treatment finishes is put into the heating furnace 91a of liquefying apparatus 91, passes through it
The intervention of fireplace melts in burner 91b under about 250 DEG C or so of heating temperature.Macromolecule after melting is supplied to heat
In dore furnace 91c, by the intervention of its fireplace in thermal decomposition furnace 91c, carried out under the further high-temperature heating of burner 91b
Thermal decomposition generates thermal decomposition gas.After resulting thermal decomposition gas is by catalyst 91d, cooled down in condenser 91e,
Recycle it is condensing after oil OL.Oil OL after recycling is stored in oil storage tank 91f.Since the residual gas after Oil recovery is can
Combustion property, burner 91b can be supplied to as auxiliary fuel.And high molecular waste material PW is adding the equipment in Fig. 3 in order to prevent
It is detained in hot stove 91a and thermal decomposition furnace 91c, is recycled the melt substance in two stove 91b, 91c by circulating pump 91g.Figure
In symbol 91h be in high molecular waste material PW heating, the melting of heating furnace 91a the low-molecular-weight gas that generates carry out it is cold
But, dedusting, clean after be discharged into exhaust gas treatment device in air.
But above-mentioned legacy device can have the following problems：
Such as be supplied to heating furnace 91a high molecular waste material must first pass around as described above pre-processing device 90 into
Row pre-treatment can cause the installation cost of integral device, running cost to increase in this way, there are it is less economical the problem of.And heating furnace
The thermal energy mainly macromolecule heat transfer by heat exchange pattern into stove of 91a, burner 91b.This is because high molecular melting
Object is high-viscosity material, convection current is difficult to happen in stove, and macromolecule is that pyroconductivity is low, is difficult the substance of heat transfer.Therefore
The melting of the high molecular waste material of heating furnace 91a takes a long time.That is slave device starts operation to actually starting back
Process until receiving oil takes a long time.So, it is contemplated that the fuel consumed during this period is more, and there are fuel
The problem of utilization rate is low.
In addition with since high molecular waste material is difficult to conduct heat, the incidence of heating furnace 91a overheats increases, and easily causes
Furnace body damage problem.And high molecular waste material is various types, the macromolecule mixture of various molecular weight, is put into together
To the uniform melting of same time is difficult to if heating furnace 91a, the substance that can only easily melt calmly starts sequence and dissolves.Thus it can produce
The raw fusant composition moment being initially supplied from heating furnace 91a to thermal decomposition furnace 91c is changing, and is produced therewith in thermal decomposition furnace 91a
Raw thermal decomposition gas and the composition of oil OL that is recycled also change the problem of astatically.
This problem would have to increase pre-treatment step or even also to increase the separation of high molecular material in order to prevent
Process, but be very difficult certainly for depending the unresolvable macromolecule of appearance alone to carry out detached job, it may result in this way
The problem of operating cost increase.And high molecular fusant is easily trapped in heating furnace 91a and in thermal decomposition furnace 91c.
It is detained in order to prevent, is recycled the fusant in two stove 91b, 91c by circulating pump 91g as described above.But once
Stop heating, the fusant in piping will solidify, and circulating pump 91g is difficult to restart.Once therefore starting device, would have to
Continuous operations always for a long time, such as can stop until the next time of circulating pump 91g safeguards.
High molecular waste material in thermal decomposition furnace 91c is by thermally decomposing the thermal decomposition gas generated, the carbon of constituent
Number changes with the temperature change of thermal decomposition.That is, the carbon of the higher gained oil constituent of heat decomposition temperature
Just smaller and numerical bias range can also become smaller number；But more high temperature, the excessive heating state of thermal decomposition furnace 91c will increase
Add, furnace body also becomes easily to damage.Close-burning phenomenon nearby easily occurs for the internal face of thermal decomposition furnace 91c, has harm on internal face
The problems such as hindering the precipitate of heat transfer, easily causing thermal decomposition inefficiency.
Usually the heat decomposition temperature of thermal decomposition furnace 91c is set in less than 500 DEG C, specially 300~400 DEG C or so, institute
The thermal decomposition gas of generation will be formed since the low molecular weight compositions of one digit number to the macromolecule ingredient of carbon number 40 or so
The mixed gas that diversification is formed.Therefore in order to reduce the carbon number value deviation range of thermal decomposition gas constituent, improve oil
Quality further decomposes decomposition as above-mentioned Fig. 3 by the catalyst 91d ingredients for promoting molecular weight big.Specifically, be exactly
The carbon number value for thermally decomposing the constituent of gas is converted to the hydrocarbon of about 4~10 or so carbon numbers, is promoted by catalyst 91d
Into the decomposition of high molecular weight components.
But if using nickel or zeolite etc. if catalyst 91d, especially when the material of processing be polyvinyl chloride
During waste, because easily losing activity containing more chlorion, this may result in is returned by the thermal decomposition gas of catalyst 91d
Oil (OL) composition of receipts and the problems such as the Oil recovery amount in the unit interval is unstable, easy variation.
Invention content
In view of this, it is necessary to for it is above-mentioned the problem of, provide a kind of elimination problems, providing can give up from macromolecule
