抚顺铝厂的侧插自焙阳极铝电解槽在生产过程中,需经常向槽中添加氧化铝原料;冰晶石、氟化铝、氟化镁、氟化钙、氟化锂等熔剂;补充阳极糊消耗材料。由于这些原料和材料产生粉尘飞扬和烟气挥发,被排风机抽入铝电解厂房烟道中而沉积,俗称“铝电解烟道灰”。现在铝电解厂房烟道中沉积烟道灰约5000t,使烟道截面变小,严重影响厂房内烟尘排放。沥青烟大,能见度低,给铝电解生产操作带来不便,人可能产生慢性或急性中毒;粉尘量超过50mg/m~3,长期吸入较高浓度的铝电解粉尘,能引起尘肺或铝肺等疾病。如将烟道中的沉积灰掏出当垃圾外运倒掉,粉灰随风飞扬污染环境,各种氟化物尘雾损
Fushun aluminum side of the self-baking anode aluminum electrolytic cell in the production process, the need to often add to the tank alumina raw materials; cryolite, aluminum fluoride, magnesium fluoride, calcium fluoride, lithium fluoride and other flux; supplement anode Paste consumption of materials. As these raw materials and materials produce dust flying and flue gas volatilization, the exhaust fan is pumped into the aluminum electrolysis plant flue deposition, commonly known as “aluminum electrolytic flue ash.” Now aluminum deposition plant flue deposition in the flue ash about 5000t, the flue section becomes smaller, seriously affecting the plant smoke and dust emissions. Asphalt smoke big, low visibility, inconvenience to the aluminum electrolytic production operation, people may have chronic or acute poisoning; Dust amount over 50mg / m ~ 3, long-term inhalation of higher concentrations of aluminum electrolytic dust, can cause pneumoconiosis or aluminum lung disease. If the flue ash deposition out when the garbage outfall, fly ash dusty wind polluting the environment, a variety of fluoride dust fog loss
