Description
Technical field
This utility model belongs to technical field of environment protection equipment, relates to hot dip galvanizing process equipment for collecting and processing acidity mist.
Background technology
Galvanizing, also referred to as galvanizing by dipping, is that steel component immerses a kind of method obtaining metal cladding in melted zinc liquid.Developing rapidly with high voltage power transmission, traffic, communication career in recent years, steel and iron parts requirement of shelter is more and more higher, and galvanizing demand is also continuously increased.
Steel beam column is before carrying out galvanizing, acid pickling and rust removing need to be carried out, workshop pickling zone is provided with pickling tube, pond stores hydrochloric acid solution, under normal circumstances, when workpiece immerses in the short time that pickling tube carries out pickling, owing to the release of bubble hydrogen considerably increases the volatile quantity of hydrochloric acid, especially when after low pressure weather or replacing eo-acid, workshop acid mist fills the air, low visibility, also endangers personnel health while plant equipment causes corrosion and damage, form severe working environment and serious atmospheric pollution.
At present, most enterprises adopt and reduce pickle concentration and add acid fog inhibitor to reduce harm, though the method can reduce acid mist volatilization, but still cannot meet environmental requirement.
At present the collection of galvanizing acid mist is mainly adopted monolayer filler spray column with processing, monolayer filler spray column is the absorption plant that comparison is ancient, owing to it has that framework is simple, is easy to operation, is easy to take the features such as anti-corrosion measure, still widely used by galvanizing factory at present.Monolayer packed tower is using the filler in tower as the mass transfer apparatus of contact member between gas-liquid two-phase.Monolayer filler is to huddle or to be placed on support plate in the way of whole block, and liquid sprays filler from tower top through water-distributing device, forms liquid film；Gas is sent into from the bottom of tower, is the space that adverse current continues through packing layer with liquid, and on filling surface, gas-liquid two-phase close contact carries out mass transfer, it can be seen that monolayer packed tower opereating specification is less, and the change for liquid load is especially sensitive.When liquid load is less, due to filler negligible amounts, filling surface can not moistening well, mass transfer effect sharply declines；When liquid load is excessive, easily produce again liquid flooding, liquid along packing layer flow downward time, with in reversely contact of gas, have gradually to the trend of tower wall concentration, flow quantity near tower wall is gradually increased, thus wall stream effect occurs, cause gas-liquid two-phase skewness in packing layer, make absorption efficiency decline, it is only capable of reaching the acid mist absorption efficiency of about 60%, exceedes atmosphere pollutants emission standards.Sometimes producer is in order to strengthen the absorption of acid mist, and it is forced to strengthen tower body diameter, now due to the restriction of its structure itself, very easily cause gas-liquid skewness, the phenomenon such as loose contact, efficiency is caused to decline, this phenomenon is the enlarge-effect of monolayer packed tower, and the while of secondary, also can produce to increase owing to tower diameter becomes cost that is big and that cause, cleaning maintenance trouble, the filler loss series of problems such as big grade that cloth wind inequality causes.
