废铝回收双室炉的优点

1、废铝回收双室炉的优点一一为什么选用双室炉熔废铝Advantages of TCFComparing TCF to other existing technologies for melti ng scrap, esp. for melting contaminated and thin scra p, the TCF has several remarkable advantages：双室熔化炉与其它废铝熔化炉，特别是在熔化含杂质废料和薄壁废料的情况下比较，有以下显著优点:Environmental pollution 环保方面The process in the closed chamber

2、s of the TCF enable s complete controlled burning of the contaminants. Theprocess of pyrolys the contaminants takes place ina closed chamber without any pollution to the atmosphere or to the building. Controlled burning and afte r burning of the pyrolysed gases from Scrap Chamberin the Heating Chamb

3、er burners and also quenching t he flue gas in the regenerator provide remarkably red uced contaminants in the gas led to the bag house.双室炉的密闭双室确保处理过程中杂质燃烧得到完全控制。杂质热分解 发生在密闭炉室内，不会污染大气和车间。可控的燃烧和加热室烧嘴对 废料室热分解气的二次燃烧以及烟气在换热器内的快速冷却显著地减 少了通向废气处理单元的污染物。Energy consumption 能耗By the covered area on the scrap

4、chamber the energyconsumption will be drastically reduced, because ofreduced heat loss from the bath area to the environ:ent. By the integrated regenerative system the heat l oss will be reduced additionally and the heat can beused for heating the furnace directly.废料室能耗由于封闭熔池向环境散热的减少而显著减少。中央换热系 统可进一

5、步减少热损失，且其热能可直接用来加热炉室。Using the heat from the contaminants 利用污染物的热量The process of controlling the pyrolysis gas and burn ing it in the heating chamber supports heating the f urnace by using the combustibles containing in the py rolysis gas and thereby reduces the energy consumption控制热分解气并在加热室作二次燃烧，热分

6、解气中可燃烧成份的热量减少了能耗。Metal loss金属烧损方面This furnace has no salt needed for avoiding oxidation of the liquid metal because of the closed scrap c hamber the metal loss by oxidation will be reduced d ue to the controlled reduction atmosphere within the scrap chamber. This atmosphere will be maintained forcon

7、taining no oxygen. No oxygen means, no partner for producing aluminium oxides and therefore all the metal will be molten to be part of the metal bath a nd not part of the dust send to the filter plant a nd also will not part of the dross removed from thefurnace. This is very important to thin-walled

8、 scrapwhich provides a big surface for reaction with oxyg en.该炉型不需盐作覆盖剂来避免铝液氧化，因为密闭废料室气氛为可控的 还原性气氛，由氧化引起的烧损大大减少。该气氛不含氧，不含氧意味 着不会产生氧化铝，因此，铝将熔于熔池，不会成为粉尘的一部分被导 向废气处理设备，也不会成为熔渣的一部分被扒渣扒出。这一点对于薄壁料特别重要，因为薄壁料有更大的表面积与氧反应。Putting the contaminated scrap into the bath directlywithout preheating and pyrolysing w

9、ill increase themetal loss by oxidation, because the contaminants arecontaining oxygen, which will react with liquid aluminium immediately.将含杂质的废铝在未经预热和热分解的情况下直接加入到熔池中会加金属的氧化损失。因为杂质中含氧，直接加入到铝液中，会立刻与铝 液发生反应。The incorporation of hydrogen will be avoided becauseof not getting fresh air contacting the l

10、iquid meta l.由于没有新鲜空气与铝液接触，避免了氢气的溶入。The special burner arrangement on the heating chamberin connection with the atmosphere control will support an equal heating of the bath area without hot sp ots on the bath and with a minimum oxygen concentrat ion. Hot spots on the bath area will increase drossfor

11、mation and hydrogen absorption.加热室烧嘴的特殊布置及气氛控制系统的配合使熔池表面加热均衡，不会在熔池区域形成过热点，氧浓度最低。熔池内的过热点将增加熔渣的形成和氢的吸入。Safety 安全方面Because of safety reasons the operation of open bathareas should be history. When putting scrap into ametal bath this material should have been dried bef ore. This is the only way providin

12、g safe operation w ithout any explosion.由于安全方面的原因，开放式熔池已成为历史。废料加入熔池前应已被干燥，这是保证操作安全、不发生爆炸的唯一方法。Additionally the closed chamber supports safe operationThe wet material will be preheated on the furnacebridge before going to the bath and will have no explosion happened. All the treatment will take placewithin the closed chamber and will not have any impact on the operators or equipment installed around.密闭炉室的操作安全。湿料在被送进熔池前将在炉子的炉桥上被预热， 不会发生爆炸。所有处理均在密闭炉室内进行，不会对操作者及炉子周 边设备产生影响。Working environment 工作环境With the automatic control and the sophisticated opera ting tec
