Abstract
The invention relates to a collaborative disposal method for leaded glass of waste cathode ray tubes and lead plaster of waste storage batteries. The method comprises the steps: coarsely crushing the leaded glass of the waste cathode ray tubes, so as to obtain glass blocks with the diameter less than 3cm; mixing the lead plaster of the waste storage batteries and the glass blocks, adding some other fluxing agents, such as calcium carbonate, iron chippings or pyrite cinder, and mixing; and enabling the mixed material to enter a smelting furnace, and carrying out reduction with charcoal, thereby producing crude lead and smelting residue. According to the method, the lead recovery rate of the lead plaster can reach over 90%, the lead recovery rate of CRT (Cathode Ray Tube) cone glass can reach over 80%, and the content of lead in the smelting waste is lower than 2.2%; the produced crude lead can be further refined, so as to prepare lead alloy or fine lead; and the method is strong in adaptability, is environment-friendly and economical and can be applied to large-scale industrial production.
Description
Technical field
The present invention relates to danger wastes harmlessness disposing field, be specifically related to a kind of useless cathode tube flint glass and used and scrapped battery lead plaster cooperative disposal method.
Background technology
Cathode tube (CRT) be suitability for industrialized production the earliest, most widely used technique of display, the advantages such as the maturation, reliability of possessing skills is high, long service life, before being replaced by plate of flat liquid crystal display (LCD) gradually the nineties in last century, it is the main display equipment of the electronicss such as televisor, graphoscope and oscilloscope always.According to conservative estimation, the whole nation is approximately 6,000,000 tons of the CRT of use electronic glass quality, and always lead tolerance is approximately 500,000 tons.According to Department of Commerce's household electrical appliances old for new service statistic data, 2011, approximately 6129.2 ten thousand of waste household appliances were reclaimed in national household electrical appliances old for new service, 5149.7 ten thousand of waste and old televisors, and in the household electrical appliances that namely China reclaims at present, 82% is the televisor of CRT monitor.CRT glass bulb is the important component part of indicating meter, accounts for 60% of total mass.Due to high lead tolerance in CRT cone glass, countries in the world are recognized the incorrect processing of these waste and old CRT glass bulbs gradually, will form serious harm to HUMAN HEALTH and ecotope.China < < electronic waste contaminate environment prevent and treat management method > > clearly regulation CRT glass bulb be danger wastes.The recycling of the especially leaded cone glass of CRT glass is the key point of China's waste and old electric changing rejected material to useful resource.
Since 2011 " household electrical appliances old for new service ", China CRT televisor has started to enter scraps peak period, and later ten years have ten thousand tons of cone glass of 5-13 to produce every year.CRT cone glass can be used for that CRT glass bulb is produced again, building material, the extraction of metallic lead and the flint glass of other types.After 2005, TV market is acutely adjusted, under the impact of LCD TV, plasm TV etc., and the quick atrophy of the market share of CRT televisor.The material of construction of CRT glass manufacture is as requisite qualities such as multicellular glass, glass-ceramic, ceramic glaze, concrete, but has been difficult to accept compared with similar lead-free product people, there is no better market outlook.Although it is high to be exclusively used in method for vacuum smelting, the mechanical activation method metallic lead recovery resource utilization efficiency of the plumbous smelting of CRT glass, at present still in the laboratory study stage.The Britain nulife electric furnace of the special smelting CRT cone glass bringing into operation for 2012, although have a small amount of application American-European, because of its high investment in fixed assets and running cost, cannot actual industrialization produce in China.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, a kind of useless cathode tube flint glass and used and scrapped battery lead plaster cooperative disposal method have been the object of the present invention is to provide
,the present invention by the lead plaster of useless cathode tube flint glass and waste lead storage battery existing industrial furnace as smelting furnace, blast furnace etc. in associated treatment, can extract the lead in flint glass, leaded below 2.2% in the waste residue obtaining.
To achieve these goals, the technical solution used in the present invention comprises the steps:
Step 1) the separated useless cathode tube flint glass coarse crushing obtaining of CRT cone screen obtains the glass block below 3cm;
Step 2) used and scrapped battery lead plaster is mixed with above-mentioned glass block, add calcium carbonate, bushel iron bits or pyrite cinder, mix;
Step 3) mixing rear material enters smelting furnace with charcoal reduction generation lead bullion and smelts residue; Smelting temperature is 900 ~ 1200 ℃, and smelting time is 4h.
Described glass block: used and scrapped battery lead plaster: calcium carbonate: the part by weight of bushel iron bits is 1-50:100:1-14:2-12.
Described glass block: used and scrapped battery lead plaster: calcium carbonate: the part by weight of bushel iron bits is 5:20:3:2.
Described bushel iron bits can be pyrite or pyrite cinder.
State step 1) in jaw crusher or roll crusher, carry out coarse crushing.
Described step 3) in, smelting furnace is smelting furnace, blast furnace or reverberatory furnace.
After the leaded waste lead accumulator pre-treatment of CRT, produce grid and used and scrapped battery lead plaster, grid recycles separately, and used and scrapped battery lead plaster is raw material of the present invention.
Method of the present invention can extract the flint glass lead of the cathode tube that gives up (CRT), and the lead recovery of lead plaster can reach more than 90%, and the plumbous rate of recovery in CRT cone glass can reach more than 80%, and the lead content of melting waste slag is below 2.2%.The lead bullion of output further refining is made lead alloy or lead bullion.Present method strong adaptability, environmental protection and economy, can be applicable to scale operation.
