一种预焙阳极生胚生产排放的沥青烟净化器A kind of asphalt fume purifier for the production of prebaked anode green body

技术领域technical field

本实用新型涉及一种气体净化器，特别是一种预焙阳极生胚生产排放的沥青烟净化器。The utility model relates to a gas purifier, in particular to an asphalt fume purifier which is discharged from the production of prebaked anode green embryos.

背景技术Background technique

预焙阳极是预焙槽铝电解生产的心脏，不仅作为导电电极把电流导入电解槽，而且参与氧化铝电解的电化学反应，重要性不言而喻，但预焙阳极的生产，尤其是生坯的生产过程伴随产生大量的沥青烟，不仅给周围环境造成严重污染，而且也造成沥青这一生产原料重大浪费。目前，对沥青烟的治理大都采取燃烧法，该方法工艺简单，治理沥青烟对环境污染的效果尚可，但存在燃烧沥青烟产生二次废气及无功燃烧沥青烟并不解决预焙阳极生坯生产产生沥青烟给沥青这一生产原料带来浪费的弊端。The prebaked anode is the heart of the aluminum electrolysis production in the prebaked tank. It not only acts as a conductive electrode to introduce current into the electrolytic tank, but also participates in the electrochemical reaction of alumina electrolysis. The importance is self-evident, but the production of prebaked anodes, especially raw The billet production process produces a large amount of asphalt fume, which not only causes serious pollution to the surrounding environment, but also causes a great waste of asphalt, a raw material for production. At present, most of the control of asphalt fume adopts the combustion method. This method has a simple process and the effect of controlling asphalt fume on environmental pollution is acceptable. However, the secondary waste gas generated by burning asphalt fume and the reactive combustion of asphalt fume do not solve the problem of prebaked anodes. Billet production produces asphalt fume, which brings waste to the production raw material of asphalt.

Such asphalt fume purifier is driven by induced draft fan, and the asphalt fumes collected by each fume collecting hood above the prebaked anode green production equipment will be sucked into the main fume pipe through the flue gas branch pipe, and then passed through the main fume pipe and the main fume pipe. The powder feeder installed in the smoke pipe is sent to the bag filter. When passing through the powder feeder, it encounters the carbon powder added by the powder feeder. The high-viscosity bitumen in the asphalt fume will be absorbed by the carbon powder to form particles. , The asphalt-coated carbon particles with a large specific gravity will fall directly into the ash hopper after entering the bag filter. The attachment of dust on the filter bag will prolong the cleaning cycle and service life of the filter bag of the bag filter, and through the bag filter, the flue gas will be separated from gas to solid, and the purified gas will be guided by the induced draft fan and enter through the air duct.
