Description
Technical field
The invention belongs to composite material recycling field, especially with rear, surface by oil pollution, cannot be used continuously
The recycling of fibre reinforced composites sucker rod.
Background technology
It is many that fibre reinforced composites sucker rod has that intensity is high, light-weight, corrosion-resistant, tar productivity is high, low energy consumption etc.
Advantage has begun to be paid attention to by oil recovery domain expert and scholar, has carried out research of technique and has started to promote the use of.
With increasing for usage amount, the sucker rod etc. of performance decline cannot be used continuously after waste and old sucker rod, abrasion
Sucker rod quantity can sharply increase.As solid waste, burning processing will produce a large amount of toxic and harmful gas, influence environment；It fills out
Burying processing can on the contrary operate when measuring small, but with the raising of dosage, the cost of landfill disposal can greatly improve, and
And composite material can be also landfilled, and cannot be used continuously, this is huge waste, and fibre reinforced especially with high costs is multiple
Condensation material.So the problem of recovery processing for the composite material material oil pumping that cannot be used continuously is a very severe, it will shadow
Ring promoting the use of for this Novel sucker rod.
Invention content
In order to solve the deficiencies in the prior art, an object of the present invention is to provide a kind of fibre reinforced composites oil pumping
The recovery method of bar can either effectively solve the problems, such as waste and old oil pumping processing, and can recycle the crude oil that sucker rod surface speckles with,
The reinforcing fiber in sucker rod can also be recycled, the utilization rate of material is substantially increased, increases economic efficiency, while can be accomplished again
Do not influence environment.
To achieve the goals above, the technical scheme is that：
A kind of recovery method of fibre reinforced composites sucker rod enhances the waste and old fibre that unrecovered oil is contained on surface
Composite material sucker rod carries out the unrecovered oil on soaking and washing removal surface using mixed solvent, then the residual stone that will remove surface
The sucker rod of oil is heated to 300~600 DEG C of matrix resins by fibre reinforced composites and decomposes, and waste and old fibre is obtained to recycle
Carbon fiber and/or glass fibre in dimension enhancing composite material sucker rod；Wherein, the mixed solvent is molten by liquid alkane class
Agent, aromatic hydrocarbon solvent, polar molecule solvent composition.
The waste and old sucker rod surface of recycling, processing is needed generally all to be stained with the untreated heavy oils such as oil, so
Need to clean up in the oil that surface speckles with, the surface oil of cleaning method existing to(for) sucker rod be hot diesel oil clean and
Hot water and cleaning agent cleaning.And existing sucker rod is metal material, and light oil, mink cell focus are not only contained in the crude oil of exploitation
Etc. oil, also colloid, asphalitine and carbonaceous etc., and sucker rod surface can not only adhere to heavy oil matter in oil recovery process, can also
Colloid, asphalitine and carbonaceous etc. are adhered to, oxide (such as carbonyl, hydroxyl are contained in colloid, asphalitine and carbonaceous, especially colloid
Base, ketone, ester, acid anhydride etc.) and sulfide (sulfone), the sucker rod of metal material for a long time can be by oxidation corrosion using rear surface, and glue
Oxide and sulfone in matter and the metal oxidation complexation after corrosion, meanwhile, a large amount of naphthalene, fluorenes etc. are also contained in colloid and passes through π-π
Conjugated together so that the unrecovered oil for being adhered to metal material sucker rod surface is difficult to be removed, thus, for
The sucker rod of metal material generally uses hot water and cleaning agent to clean, and is purged using scratchbrusher.And fiber is increased
Strong composite material sucker rod, either cleaning agent or scratchbrusher, all can in fibre reinforced composites carbon fiber and/
Or glass fibre generate damage, to be difficult to in fibre reinforced composites sucker rod carbon fiber and/or glass fibre into
Row recycling.
The present invention uses mixed solvent first, and soaking and washing, 1. fiber reinforcements are carried out to the unrecovered oil on sucker rod surface
Metal is free of in composite material, so that cleaning agent cleaning is not used to be possibly realized；2. using mixed solvent, residual is increased
The solubility of oil, so as to completely remove the unrecovered oil on fibre reinforced composites sucker rod surface.Secondly, it removes
The sucker rod of remained on surface oil is heated to 300~600 DEG C, and composite matrix resin decomposes, and reinforcing fiber heatproof is high,
It will not decompose at this temperature, so after dore furnace, matrix resin decomposes, and has obtained reinforcing fiber.
The second object of the present invention is to provide a kind of device for realizing the above method, including surface oil sweep accumulator tank and
Dore furnace, mixed solvent is filled in the surface oil sweep accumulator tank, and the waste and old fibre enhancing that unrecovered oil is contained on surface is multiple
Condensation material sucker rod sequentially enters surface oil sweep accumulator tank and carries out soaking and washing, enters back into dore furnace by fiber-reinforced composite
Matrix resin in material sucker rod decomposes.
The third object of the present invention is to provide a kind of regeneration sucker rod, the carbon fiber and/or glass recycled using the above method
Glass fiber is as reinforcing fiber.
The fourth object of the present invention is to provide a kind of preparation method of regeneration sucker rod, including the above method, by recycling
After carbon fiber and/or glass fibre pour into a mould matrix resin as reinforcing fiber.
Beneficial effects of the present invention are：
1. cleaning agent is not added in the present invention, the chemical constitution of unrecovered oil is not changed, so as to realize to oil pumping
The unrecovered oil on bar surface is recycled again.
2. the present invention improves stock utilization and economic benefit, waste and old fibre enhancing composite material sucker rod processing is solved
A great problem.
