Abstract
The invention discloses a water circulation method in a regenerated aluminum-plastic composite product separation process, and relates to the technical field of resource recycling. The water circulation method comprises the following processing steps: 1) pumping water in a hydrolytic tank into a plate-and-frame press to filter, flowing filtered water into a reflux tank, and returning a filter residue to the hydrolytic tank to be separated; 2) adjusting the pH value of water in the reflux tank to keep the water in the reflux tank neutral, and then putting the water in the reflux tank into a stewing pool to be stewed for 7-15 days; 3) flowing the water at the middle and upper parts of the stewing pool into an SBR pool to carry out aerobic biochemical treatment, and flowing supernate after stewing in the SBR pool into a regulating reservoir; 4) filling clean water into the regulating reservoir, and putting the water in the regulating reservoir into a clean water basin, wherein the water in the clean water basin is supplied to the hydrolytic tank to be used. The wastewater is comprehensively utilized in cycle, so as to achieve zero emission and zero pollution. The water source can be supplied after the water source in the circulation system is naturally consumed, so that the system is simple in process and convenient to operate, the environment can be effectively protected, and water resources are saved.
Description
Technical field
The present invention relates to resource reutilization technical field, be specifically related to a kind of water cycle method in regeneration plastic-aluminum composite product separating technology.
Background technology
Aluminium scrap is moulded goods through processing, and can reclaim aluminium and plastics, and the aluminium of recovery and plastics can directly or be applied to decoration, finishing and packaging etc. after modification, apply more and more extensively, have higher recovery value.Under the overall situation reduce gradually in resource, price increasing gradually, if can be recycled, important economic worth and energy-saving and emission-reduction meaning will be there is.
At present, plastic-aluminum separating method is common acid-soluble or the molten partition method of alkali, weak acid multi_layer extraction method and a demixing of solvents partition method etc.Utilize aluminium can be dissolved in the principle of soda acid, use method acid-soluble or that alkali is molten the al dissolution in material, thus recycled plastic, and then aluminum bearing waste is made to polymerize aluminum chloride or Tai-Ace S 150.This acid-soluble or molten partition method of alkali has the halfway shortcoming of recovery.
In addition, utilize organic monoacid molecule can permeate plastic layer as acetic acid, formic acid etc., so dissolve each layer of bonding aluminium oxide compound and the aluminium in wrapping material and plastics are distinguished complete separation by the characteristic that can not dissolve pure aluminum.This weak acid multi_layer extraction method has long reaction time, shortcoming that separation efficiency is low.In addition, utilize plastics by organic solvent as the character of the swelling such as toluene, chloroform, with an organic solvent to make plastics swelling, aluminium is peeled off from plastic-aluminum sheet, then recycle respectively.This demixing of solvents partition method has the shortcoming that solvent consumption is large, toxicity is large, cost is high, and can produce more waste water in removal process, and the wasting of resources is larger.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of environmental pollution that reduces, water cycle method in the regeneration plastic-aluminum composite product separating technology of raising resource utilization.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of regeneration plastic-aluminum composite product environmental protection separating technology, comprises following processing step,
1) purchase sorting: from the regeneration plastic-aluminum goods (as plastic-aluminum cable, aluminum-plastic composite membrane, aluminium plastic composite packaging paper etc.) of various places purchase different colours, specification, by manual removal, extract after the impurity elimination of copper core, unification is stacked plastic-aluminum goods neat;
2) separate first: the regeneration plastic-aluminum goods unification after impurity elimination is put into high speed disintegrator, carry out fragmentation, be processed into the plastic-aluminum piece of block specification;
3) secondary separation: block plastic-aluminum is transported to the reactor of semitight by travelling belt, passes into and be steam heated to 100 DEG C, the temperature profile different according to plastic-aluminum, within 30-120 minute, make the aluminium plastic material being tightly combined with each other, separate gradually, obtain purity higher aluminum and mould parting material;
4) aluminum-plastic separation material is put into high-speed grinder and grind, cross 80-150 mesh sieve, then the aluminum-plastic separation materials processing of powdery is become to particulate state plastic-aluminum mixing material;
5) separate for three times: particulate state plastic-aluminum mixing material is placed in to hydrolytic tank by transport unit, in hydrolytic tank, inject normal-temperature water, utilize the mobility of stirring wheel and water, make granular plastic-aluminum mixing material through overcooling, natural separation after expanding with heat and contract with cold, utilize its different density, on plastics, float, aluminium powder sinks;
6) plastic grain floating in collection and the aluminium powder of sinking, obtain purity and reach 99% plastic grain and aluminium powder;
7) by plastic grain and aluminium powder airing (oven dry) respectively, after being dried, unitizing warehouse-in, aluminium powder is for the preparation of aluminum products such as aluminium bars, and recycled plastic granules is for the preparation of plastics such as battery jars.
A kind of water cycle method in regeneration plastic-aluminum composite product separating technology, comprises following processing step,
1) water in hydrolytic tank is pumped into flame filter press and carry out filtration treatment, the water after filtration flows into backflow pool, and filter residue comes back in hydrolytic tank and separates;
2) the pH value of water in adjusting backflow pool, makes the water in backflow pool keep neutral, then the water in backflow pool is put into standing pond, leaves standstill 7-15 days;
3) will leave standstill middle and upper part, pond and divide water to carry out aerobic treatment from flowing to SBR pond, after SBR pond leaves standstill, supernatant liquor flows into equalizing tank;
4) in equalizing tank, fill into clear water, then the water in equalizing tank is put into clean water basin, the water in these clean water basin is used for providing hydrolytic tank to use.
The invention has the beneficial effects as follows: the present invention fully utilizes waste water circulation, reach zero release, zero pollutes; after the water source in the recycle system consumes naturally, can supplement it, system process is simple; easy to operate, effectively protection of the environment, saving water resource.
