Description
Technical field
The invention belongs to fluorescent tube lighting technical field, particularly relate to a kind of recoverying and utilizing method of waste fluorescent lamp.
Background technology
Current China fluorescent-lamp tube output and use amount occupy first place in the world, the old mercury lamp produced and fluorescent tube reach more than 10 ten thousand tons, wherein the overwhelming majority all enters refuse landfill with house refuse, the mercury disengaged every year and compound number are in hundred tons, severe contamination soil and groundwater source, chronic murder by poisoning health.
It is reported, within 2003, China produces fluorescent lamp about 1,000,000,000, props up, mercurous total amount about 30 tons in fluorescent lamp by average mercury content 30mg/.The mercury quantity consumed in actual production process is far longer than this numeral.For the T12 straight tube fluorescent lamp of 40W, note mercury by automatic assembly line, need injection 20 ~ 40mg/ to prop up, add processes expend, actual consumption mercury quantity is that 60 ~ 100mg/ props up.Calculate accordingly, actual consumption mercury quantity average out to 45 ~ 48mg/ that China's fluorescent lamp is produced props up, produce per year mercury quantity that 1,000,000,000 fluorescent lamps consume be 45 ~ 48 tons 2007 years, the fluorescent lamp output of China has reached 1,500,000,000, mercurous total amount in fluorescent lamp will reach 70 tons, produce the mercury quantity consumed and reach about 80 tons.Meanwhile, also to consume copper 3000t, 5000 tons, aluminium and 60 tons, tungsten.
Present status in China, because the recycling of China's waste fluorescent lamp is at the early-stage, establishes the recycling consciousness of waste fluorescent lamp not yet completely.Fluorescent tube is normally broken by the processing method of major part waste fluorescent lamp, then abandons with newspaper Bao Lost.This kind of way is quite dangerous, because while fluorescent tube is broken, the most of mercury vapour in fluorescent tube will overflow and shed, once enter human body via respiratory tract, will live forever in body, the nervous system of injury human body.At present, the domestic way also not having system effectively to process waste fluorescent lamp, a lot of hazardous waste disposal unit is collected and is left concentratedly; Consulting relevant contexts protection department, does not have clear and definite answer yet.Have an enterprise to process waste fluorescent lamp at present, but smash nothing more than and extract useful metal, the residue serious to remaining harm does not process with not carrying out effective and safe.
Foreign current situation: the process of external waste fluorescent lamp mainly contains directly broken apart and cut end purging and be separated two kinds of techniques.Directly broken apart feature is that compact conformation, floor space are little, small investment, but fluorescent material and mercuryvapour are not recycling.And cut the fluorescent material categorised collection of holding and purging and being separated and can effectively will be able to being recycled, but investment is larger.At present, in order to promote Green Lighting Project, reduce environmental pollution, some large-scale Illumination Enterprises have started the recovery operation of carrying out waste fluorescent lamp.But current recycle object is also only limitted to the large enterprise of fluorescent lamp use amount, and set up recycle bin at main dealer place, these companies are just planning as recovery used batteries, the recycling work of universal waste and old fluorescent lamp.But this measure is also only in the stage of ground zero, still do not form ripe effective system.
Summary of the invention
The object of the invention is to: for the deficiencies in the prior art, and a kind of recoverying and utilizing method of waste fluorescent lamp is provided, the method can realize the utilization again of waste fluorescent lamp, achieve the recovery of glass tube, metal cap, fluorescent material and mercury vapour, effectively control the pollution of waste fluorescent lamp to environment, effective recycling has been carried out to resource.
In order to achieve the above object, the present invention adopts following technical scheme: a kind of recoverying and utilizing method of waste fluorescent lamp, waste fluorescent lamp is dismantled, isolate discarded glass pipe, metal cap, fluorescent material and mercury vapour, then they are proceeded as follows: 1) discarded glass pipe is collected: the glass tube of different size is blocked into short glass tube, and this short glass tube can utilize again; 2) collection of metal cap: collected by waste and old metal cap, carries out sorting to metal cap, extracts aluminium material; 3) collection of fluorescent material: scraped off by the fluorescent material in fluorescent tube, melts down smelting and obtains finished product fluorescent material; 4) collection of mercury vapour: adopt vacuum pump to be collected by mercury vapour, then mercury vapour is fixed liquefaction and obtain mercury.
One as the recoverying and utilizing method of waste fluorescent lamp of the present invention is improved, and described short glass tube can be made into the glass tube of same size again, realizes the utilization again of glass tube.
One as the recoverying and utilizing method of waste fluorescent lamp of the present invention is improved, discarded glass pipe is collected can also in the following ways: after being cut by the described metal cap at two ends, directly clean can again utilization is carried out to glass tube, solve the problem that LED dazzle is dazzling, or be directly used in LED lamp tube after rejoining frosted of dusting.
One as the recoverying and utilizing method of waste fluorescent lamp of the present invention is improved, and the sorting of described metal cap is divided into twice, after metal cap fragmentation, carries out first time sorting to metal cap, isolates metal object and insulating resin; Then second time sorting is carried out to metal object, be separated the metal object of copper, aluminium, iron and tungsten, finally return smelting and obtain finished product copper, aluminium, iron and tungsten.
One as the recoverying and utilizing method of waste fluorescent lamp of the present invention is improved, and after discarded glass pipe cuts, reclaims obtain fluorescent material by the direct washing and filtering of pressurization hydraulic giant.
One as the recoverying and utilizing method of waste fluorescent lamp of the present invention is improved, described fluorescent material is halogen calcium phosphate fluoressent powder and rare-earth trichromatic fluorescent powder composition, and halogen calcium phosphate fluoressent powder is in fluorine chlorapatite matrix, mix the fluorescent material made after a small amount of activator antimony and manganese; Rare earth element in rare-earth trichromatic fluorescent powder can be used as the matrix components of fluorescence luminescent material, also can be used as the activator of fluorescence luminescent material, coactivator, sensitizer or dopant.
Beneficial effect of the present invention is: method of the present invention comprises, waste fluorescent lamp is dismantled, isolate discarded glass pipe, metal cap, fluorescent material and mercury vapour, then they are proceeded as follows: 1) discarded glass pipe is collected: the glass tube of different size is blocked into short glass tube, and this short glass tube can utilize again; 2) collection of metal cap: collected by waste and old metal cap, carries out sorting to metal cap, extracts aluminium material; 3) collection of fluorescent material: scraped off by the fluorescent material in fluorescent tube, melts down smelting and obtains finished product fluorescent material; 4) collection of mercury vapour: adopt vacuum pump to be collected by mercury vapour, then mercury vapour is fixed liquefaction and obtain mercury.The method can realize the utilization again of waste fluorescent lamp, achieves the recovery of glass tube, metal cap, fluorescent material and mercury vapour, effectively controls the pollution of waste fluorescent lamp to environment, has carried out effective recycling to resource.
