Description
Technical field
The present invention relates to a kind of recovery and treatment method of controlling broken dust that produces of waste fluorescent lamp and mercury gas discharging.
The invention still further relates to a kind of device of realizing said method.
Background technology
In the society, energy resource consumption progressively aggravates in modern times, and environmental pollution is serious day by day, and the cry of Green Lighting Project is increasingly high, and the recovery of discarded fluorescent lamp has also been caused people's huge concern with disposing.As everyone knows, the fluorescent tube inwall scribbles fluorescent material, and mercury vapour and argon gas are housed in the pipe.If broken fluorescent tube accidentally, the fluorescent material of the mercury vapour in the fluorescent tube and poisonous (containing heavy metal) can spread to rapidly in the room air, is caused acute mercury poisoning by a large amount of suction of people, and children come to harm more easily.According to " national hazardous waste register 2008 ", the useless mercurous fluorescent tube that produces in producing and selling and the use belongs to the mercurous refuse of HW29, handles improperly to produce huge threat to the person and Environmental security.If discarded fluorescent tube is arbitrarily abandoned, these pollutants will get in soil, air and the river, cause serious environmental problem.The recycling treatment of waste electronic fluorescent lamp has become the current problem that needs to be resolved hurrily, and causes extensive concern both domestic and external.
At present, mainly contain for the discarded fluorescent lamp processing method both at home and abroad and add sulphur landfill method, burning method and recycling method.Add the sulphur landfill method and mainly be to eliminate the pollution of mercury to environment, purpose is to solidify mercury with the form of mercuric sulphide.Mercury in soil often with Hg
0, Hg
1+And Hg
2+Three kinds of valence states exist, and between three kinds of valence states, are changing under the different natural conditions.Simple landfill can not make mercury wherein decompose destruction, and can only shift the position and its physics and chemistry form of transformation of its existence.For burning method, effect is more undesirable, and 90% mercury directly gets into atmosphere in the fluorescent tube, and the plastic components in the lamp holder changes into the dioxin deadly poisonous compound through burning.Because mercury is the heavy metal of effumability, general sulphur landfill method and the burning method of adding realized that only the transfer of mercury state or position changes and do not reach the real purpose of processing, remains in potential threat environment.So up to the present, tool development prospect is the recycling method.The prerequisite of recycling is to be in the waste fluorescent lamp effective collection of disperseing disordered state, could realize recycling truly.
The recovery waste fluorescent lamp brief introduction of existing report is following:
1) fragmentation+magnetic separation+washing+mercury heating recovery
Granted publication CN201449974U waste fluorescent lamp recovery apparatus set comprises disintegrating machine, magnetic separator and rinsing maching.Broken material carries out sorting through magnetic separator, and carries out three stage countercurrent spray washings; Under the effect of the upper box part air exhauster that connects material, waste gas is sucked condenser system fluorescent material is separated with mercury, mercury is realized reclaiming through vacuum heater.
Publication number CN101604606A resource recycle method for waste tubes; Be that the fluorescent tube that will give up drops into disintegrating machine and under negative pressure state, carries out fragmentation; Glass after the fragmentation separates through magnetic separator with metalliferous material, and the metal after the separation is sent into rinsing maching, reclaims metal through three stage countercurrent spray washings; Mercury is realized reclaiming through vacuum heater.
The waste and old fluorescent tube processing method of Granted publication CN100400168C; It is broken that waste and old fluorescent tube gets into horizontal gyratory crusher; Mercury gas gets into absorption system under the negative-pressure air-flow guiding that blower fan produces; Sort out metal after the fragmentation, the glass fragment after the letter sorting is recycled after removing fluorescent material through washing.
More than the system process in the report is complicated, and equipment is more, and any one link is out of joint, all can have influence on the operation of whole system.
2) fragmentation+screening+magnetic separation+charcoal absorption mercury
The Granted publication CN1071150C method and system that the various material/materials of mechanical separation are used from discarded fluorescent lamp pipe and similar broken lamp; The air-flow convey materials fragment that utilizes fans drive to provide separates from knockout tower; Coarse granule carries out next step crushing and screening; And through magnetic grader glass is separated with metal, with the mercury in the charcoal absorbed air.This system process is complicated, and equipment is huge, and all is accompanied by mercury vapour in each separation process, the environmental pollution that very easily causes mercury vapour to leak.
3) classification is reclaimed
The method of the disclosed a kind of recovering and processing discarded fluorescent lamp of publication number CN101150032A with the discarded fluorescent lamp safety cutting, reclaims gas mercury; The recovery of aluminium cap, brass bolt, filament metal and the mercury that adheres to reclaim; The recovery of mercury and fluorescent material middle rare earth element and other valuable pyrogenic process Separation and Recovery in the loose fluorescent material; Element pyrogenic processes such as mercury and rare earth reclaim in glass and the fluorescent material that sticks.The shortcoming of this classified reclaiming method is that manual operation is more, has the mercury poisoning risk; Because the fluorescent tube cutting need be accomplished in organic solvent, need the waste liquid amount of processing bigger; Mercury, rare earth element and valuable element pyrogenic process separate, and it is higher to consume energy, and separation purification concentration is lower.
4) broken, spray absorbs and the collection of heating mercury
The disclosed waste and old fluorescent tube of Chinese patent CN2746981 is handled and is pulverized absorption equipment, is made up of equipment casing and the pulverizer, the spray absorption plant that are arranged in the casing.The negative pressure of utilizing the air inducing of spray absorption plant to produce directly sucks mercury vapour in the spray chamber when pulverizing fluorescent tube and is absorbed.
Granted publication CN1902723A reclaims the method for fluorescent lamp; Pair roller grating fluorescent lamp through switched in opposite; The fragment of fluorescent lamp is heated the formation mercury vapour between 100 ℃ to 330 ℃, mercury vapour is being cooled under-38 ℃ to 0 ℃ the temperature to form under liquid mercury and the collection.The shortcoming of this collection method is that the broken dust that produces does not obtain effective collection.
5) small-sized reclaimer
Authorize the method and apparatus of publication number CN101587809A mercury of waste fluorescent light tube harmless treatment and recycling, this patent has been announced a kind of small-sized mercury of waste fluorescent light tube harmless treatment and recycling and processing device.Useless fluorescent tube is put in the sealing bucket of the mercury absorber that heater, pulverizer and surface attachment elemental sulfur are housed; In the sealing bucket, will giving up, fluorescent tube is pulverized and heating makes mercury vapourization, and the simple substance on mercury vapour and the absorber vulcanizes and generates solid-state mercuric sulphide to be recycled so that concentrate.This equipment belongs to batch processed type equipment, and the work period is longer, and efficient is lower, and material barrel and main equipment connect together, and does not have convertibility; Though can in the sub-district, place use, there is dust pollution during discharge, then cause efficient extremely low if leave standstill depositing dust.
Because in the above-mentioned report, the fluorescent tube reclaimer that has is bulky, what can't arrive that waste fluorescent lamp produces carries out scene recovery dispersedly, causes the fluorescent tube can't centralized collection, Unified Treatment.
