Description
Technical field
The present invention relates to a kind of fluorescent lamp recovery process, and in particular to the discarded fluorescent lamp recycling side that can be tentatively sorted
Method.
Background technology
Since T.A. Edison in 1879 manufactures carbon fibre incandescent lamp, incandescent lamp with swift and violent speed replace oil lamp,
Candle, at necessary lighting device in for people's lives.With the development of science and technology, incandescent lamp cannot meet the need of people
It asks, although having invented volume later and the smaller halogen tungsten lamp of optrode that declines, incandescent lamp makes it by the principle that tungsten filament shines
Luminous efficiency is still relatively low.In order to save the energy, the fluorescent lamp and LED light of high-luminous-efficiency come into being.
In the application of daily life, a kind of fluorescent lamp and LED light are designed to be placed in fluorescent tube, and people claim this respectively
Kind of fluorescent lamp is fluorescent lamp, and this LED light be referred to as LED daylight lamp, commonly fluorescent lamp model T5 and T8 in Common People, T5 tables
A diameter of 5/8ths inches of bright lamp pipe, i.e., 16 millimeters, similarly a diameter of one inch of T8.With sustainable development of China plan
Propulsion slightly, higher and higher to energy saving requirement, the popularity of fluorescent lamp or LED daylight lamp also increases year by year.But
After fluorescent lamp breaks down, the fluorescent lamp for recycling substantial amounts is just needed, wherein the three primary colors fluorescent powder contained, metal, plastics, glass
All being can be with the resource of recycling.
Traditional fluorescent lamp recovery process, which mainly uses to cut after fluorescent powder is blown at both ends, is directly crushed fluorescent tube, then carries out again
Selection by winnowing, to achieve the purpose that metal, plastics, glass, fluorescent powder is separated, still, a part of fluorescent powder is to be adhered to fluorescent tube
On, by simply blowing powder process without departing from cullet, if directly broken fluorescent tube, fluorescent powder are mixed with cullet after blowing powder
It is combined, the recovery difficult of glass and fluorescent powder will be greatly increased, reduce the purity of the fluorescent powder and glass that are obtained after recycling
And quality moreover can also influence the quality of the downstream product manufactured by the glass obtained by recycling, cause to waste, against
The original intention of the waste and old fluorescent lamp of recycling.
Invention content
The technical problem to be solved by the present invention is to the defects for current waste and old fluorescent lamp recovery process, it is therefore intended that carry
For the discarded fluorescent lamp recovery method that can be tentatively sorted, it is i.e. broken after cut end blows powder to solve traditional fluorescent lamp recovery process
The fluorescent powder separating difficulty that broken fluorescent tube leads to cullet and is adhered on cullet increases, and reduces the problem of recycling product quality.
The present invention is achieved through the following technical solutions：
The discarded fluorescent lamp recovery method that can be tentatively sorted, includes the following steps：
(A) waste and old fluorescent lamp is recycled using waste and old fluorescent lamp recycling bins in residential block, and is transferred to setting and exists
In the cleaning machine of recovery workshop, using cleaning machine to being cleaned on the outside of fluorescent tube；
(B) it is sieved according to the extent of damage of fluorescent lamp：The day that lamp cap, electronic component damage but fluorescent tube are remained intact
Light lamp is sent into processing in step (C), intact for lamp cap, electronic component, but the fluorescent lamp of fragmentation occurs in fluorescent tube, recycles its lamp cap
And electronic component, the fluorescent tube of fragmentation is collected, fluorescent tube and fluorescent powder are detached by selection by winnowing, are all for lamp cap, electronic component, fluorescent tube
Intact, for no other reason than that with causing fluorescent powder to fall off and the fluorescent lamp of cisco unity malfunction for a long time, its whole lamp is recycled；
(C) both ends of fluorescent lamp are cut using cutting machine in confined space, detaches fluorescent tube and two lamp caps, goes
Except the electronic component in fluorescent tube, then electronic component, lamp cap are sent in crusher and are crushed, broken metal is broken
Piece and plastic flakes separate, and metal fragment and plastic flakes are respectively sent in metal recovery device and plastics recovery device, heating
Metal recovery device and plastics recovery device, distill the mercury being adsorbed on metal fragment and plastic flakes；
(D) fluorescent tube behind heating excision both ends, removes the mercury being adsorbed on fluorescent powder and fluorescent tube；
(E) fluorescent tube is put into ultrasonic wave pond, starts supersonic generator, ultrasonication is carried out to fluorescent tube, is reduced
Adhesive ability between fluorescent powder and fluorescent tube, the fluorescent powder being detached from fluorescent tube fall into the water, and form ultrasonication liquid containing powder, so
Fluorescent tube is sent into fluorescent tube service sink afterwards, tube inner wall is cleaned in fluorescent tube service sink, being adhered to the glimmering of tube inner wall
Light powder is scraped into fluorescent tube ejected wash water, forms fluorescent tube service sink liquid containing powder, and finally ultrasonication liquid containing powder and fluorescent tube are cleaned
Pond liquid containing powder is mixed and is filtered；
(F) fluorescent powder obtained after filtering is purified, fluorescent powder is stirred with dichloromethane, then use third
Ketone washs for several times fluorescent powder.In the prior art, the recovery process of fluorescent lamp is：Excision fluorescent lamp both ends, i.e., lamp cap it
Afterwards, it blows the fluorescent powder in fluorescent tube off using wind turbine, is then directly crushed fluorescent tube, to the cullet, metal fragment and modeling of generation
Expect that fragment carries out selection by winnowing, to achieve the purpose that metal fragment, plastic flakes, cullet are separated, still, such method is
Worthless, because some fluorescent powder is adhered on fluorescent tube, this part fluorescent powder is only carried out by wind turbine simple
It is without departing from cullet, if directly broken fluorescent tube after blowing powder, the fluorescent powder and cullet or glass being adhered on glass to blow powder
Glass slag mixes, and is not easy to separate them using the methods of selection by winnowing, electric separation, and the recovery difficult of cullet and fluorescent powder is significantly
Increase, reduces the purity and quality of the fluorescent powder and glass that are obtained after recycling；More seriously, it can also reduce by recycling
The quality of the downstream product manufactured by glass arrived, to cause to waste, against the original intention of the waste and old fluorescent lamp of recycling.
To solve the above-mentioned problems, the present invention provides a kind of techniques of the waste and old fluorescent lamp of recycling, first, in each residential block
Waste and old fluorescent lamp recycling bins are placed, returning for waste and old fluorescent lamp is not set since current promotion efficiency is inadequate, in many cells
Case is received, many residents are thrown away after even wrapping up waste and old fluorescent lamp with newspaper in dustbin.Recycling bins are transferred to later
In recovery workshop, fluorescent lamp is taken out, transfers them in cleaning machine, its surface is cleaned, because the source of fluorescent lamp is not
Together, the bacterium contained by surface, dust, sludge can increase the burden of subsequent recovery process, so needing the table to fluorescent lamp
Face is cleaned.
After cleaning, fluorescent lamp is sent to screening platform, is sieved according to the extent of damage of fluorescent lamp.Traditional day
In light lamp recovery process, some processes entire fluorescent lamp is directly carried out fragmentation then selection by winnowing separation metal, plastics, fluorescent powder and
Cullet；Some processes are crushed fluorescent tube and electronic component, lamp cap respectively after taking out electronic component, lamp cap.Such technique is
It is worthless because the fluorescent lamp extent of damage is different, corresponding to treatment process also can be different, all in accordance with the same processing side
Formula is imposed uniformity without examining individual cases, bad for the fluorescent lamp recovering effect of damage situations complexity if the process imposed uniformity without examining individual cases is simple；Such as
The process that fruit is imposed uniformity without examining individual cases is complicated, then it is impaired not serious for itself, by simply screening the day that can directly recycle
Light lamp, cost recovery increase.For example, fluorescent lamp is fluorescent tube fragmentation, but its internal electronic component is intact
, if by the way of being directly crushed, intact electronic component is just taken as the electronic component to break down and is crushed, finally
It is recycled as metal fragment, these metal fragments is handled again later, process to obtain new electronic component, this is very unrestrained
Take resource.To solve the above-mentioned problems, the fluorescent lamp after cleaning is sent into screening platform, by fluorescent lamp according to damage situations point
For three classes：The fluorescent lamp that lamp cap, electronic component damage but fluorescent tube remain intact is sent into next step and carries out cutting both ends, behind
Its step can be described in detail；It is intact for lamp cap, electronic component, but the fluorescent lamp of fragmentation occurs in fluorescent tube, select and recycling its
Lamp cap and electronic component collect the fluorescent tube of fragmentation, unified to carry out break process, and fluorescent tube and fluorescent powder are detached by selection by winnowing, due to
Fluorescent tube has been crushed, and has been lost before treatment without the fluorescent powder being adsorbed on fluorescent tube, so passing through simple wind
Choosing carries out rough screening；All it is intact for lamp cap, electronic component, fluorescent tube, is led for a long time for no other reason than that having used
It causes fluorescent powder to fall off and the fluorescent lamp of cisco unity malfunction, its whole lamp is recycled, make its regeneration by adding fluorescent powder, it can also
It is disassembled, lamp cap, electronic component, fluorescent tube is assembled into different new fluorescent lamps respectively.It, can be with by above-mentioned screening platform
The burden of subsequent technique is reduced, the fluorescent lamp lighter to the extent of damage, which can be handled slightly, to be recycled, to impaired heavier daylight
Lamp is also targetedly to be recycled according to its damaged part, avoids the resource wave caused by traditional unification is broken
Take.
