Description
Technical field
This utility model belongs to technical field of environment protection equipment, relates to hot dip galvanizing process zinc cigarette collection and treatment device.
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 product consumption is also continuously increased.
Owing to surface quickly forms oxide layer when zinc pot is properly functioning, smoke yields is less.When workpiece immerses and proposes the moment of zinc pot, due to the fluxing agent volatilization stirred and on workpiece, cause that flue gas rolls up.In zinc pot, workpiece produces a large amount of smog when carrying out galvanizing, and the principle of generation illustrates as follows: workpiece is after overpickling is derusted, and workpiece processes then through solvent ammonium chloride, and after drying, appearance is chlorinated ammonium completely and is encased.Workpiece is entering the moment of galvanized pot, due to high temperature action, causes that ammonium chloride decomposes rapidly generation HCl, it may be assumed that
NH4Cl=NH3 ↑+HCl ↑
The reactions such as oxidized with the ferrum in metallic zinc, workpiece body and the surface again zinc oxide of major part (about 80%) in the HCl gas that decomposes produces, it may be assumed that
2HCl+Zn=ZnCl2+ H2↑；
2HCl+Fe=FeCl2+ H2↑；
2HCl+ZnO=ZnCl2+ H2O↑；
As can be seen here, smog be mainly composed of the salts such as HCl, FeCl2, ZnCl2, ZnO, NH4Cl and metal-oxide flue dust, wherein based on NH4Cl, the particle diameter of these flue dust is extremely tiny, in the μ m of 0.0l～1.
At present that the collection of hot-dip galvanized cigarette and process is main in the majority in a wet process, the form namely passing through to add spray column carries out washing, purifying, but the treatment effeciency of this kind of processing mode ammonium chloride flue dust is only about 70%, and the highest reaches more than 80%.After spray column washing absorption processes, in device aerofluxus, ammonium chloride gas and dust characters is all slightly above 150mg/m3, exceedes atmospheric pollution comprehensive discharge standard, and has significantly white cigarette at air vent, and treatment effect is lower than expection.Reason is: ammonium chloride is a kind of material being highly soluble in water originally, under normal temperature and pressure, the dissolubility in water reaches 28.2%, but through thermal dissociation, meeting the cold ammonium chloride particle physicochemical properties generated that regroup and have occurred that change, its particle diameter is below 1 μm (6.2 × 10-5Cm), white smog, easily sink, also no longer soluble in water.Wet scrubber tower easily causes that the flue gas relative humidity after washing is higher, and device outlet temperature is about 20-30 DEG C, and relative humidity is about 85%-90%, therefore makes air vent produce white cigarette problem.Can dust granules mutually adhere to or adhere to the character of difficulty or ease and be called the wettability of dust with liquid, generally, is suspended in the particularly dust of less than 1 μm of less than 5 μm in gas, is difficult to be spontaneously wet out by water.Ammonium chloride flue dust particle diameter is below l μm and is likely to about be surrounded by a layer of air film, is completely cut off and comes, further increases the difficulty being spontaneously wet out by water. and chloride leach degree is substantially reduced, causes that scrubbing tower detersive efficiency is not high.The principle of scrubbing tower washing absorption ammonium chloride flue dust is similar to the principle of water dust scrubber, and because of moistening agglomeration effect, filled surface becomes the moisture film that the absorbent that biofilm shape flows down is formed to adhere to short grained flue dust, thus being purified.But only exist molecular separating force between ammonium chloride flue dust surface and water, be not enough to the cohesiveness overcome between hydrone. and be difficult to be spontaneously wet out by water, thus it is difficult to effectively be adhered to by moisture film, a part of ammonium chloride particle escapes to select liquid level, makes treatment effeciency reduce.What system adopted is periodical feeding, when processing certain time.Additionally in absorbent, ammonium chloride content reaches finite concentration, and the pH value absorbing liquid declines, and the disposal ability also leading to ammonium chloride during system reduces.
Summary of the invention
