Description
Technical field
The utility model relates to pot galvanize smoke and dust treatment technical field in the pot galvanize production, particularly relates to a kind of curtain-type soot treatment and purification system for hot galvanizing.
Background technology
Pot galvanize is to improve one of weather-resistant important means in steel piece surface, and it carries out pre-treatment with the steel piece surface earlier, immerses then in the fused zinc liquid, forms one deck zinc metal protection coating on the steel piece surface.One important process operation of pot galvanize pre-treatment during solvent treatment, it not only can remedy the deficiency that several procedures in front may exist, and can also activate steel surface, improves quality of coating, and this is unexistent in other steel anti-corrosive technologies.The most normal employing now to help the plating solvent be zinc chloride (ZnCl
2) and ammonium chloride (NH
4Cl) mixing solutions.When galvanizing, often produce bigger flue dust with between the iron and steel of zinc chloride ammonium salt film, influence the operating environment of factory.This is because the ammonium chloride (NH in the salt film
4Cl) decomposition temperature is low, far below 450 ℃ of conventional pot galvanize temperature.Ammonium chloride (NH
4Cl) decomposes can form ammonia (NH
3) and hydrogenchloride (HCl), these two kinds of gases can be combined into micron order or nano level crystal grain again above the zinc bath.So main component is ammonium chloride (NH in the flue dust
4And be attended by ammonia (NH Cl),
3), hydrogenchloride (HCl) and zinc oxide (ZnO), flue dust is white in color; If have under the situation of aluminium in the zinc liquid, also has the aluminum chloride (AlCl of cyan
3) flue dust.These gases do not have too big harm to human body, but are in for a long time in the environment of big flue dust, will produce detrimentally affect to human body yet.
For the flue dust that produces in the hot galvanizing process, domestic most of enterprises do not take appropriate measures and handle.And, generally having adopted the mode of flue dust collecting filtration treatment in American-European countries, the flue dust that is produced after collecting, is handled in strainer air-bleed system again.At present, Chang Yong gathering system has three classes: (1) side exhausting system.Along zinc pot length direction a slit-shaped suction opening is set respectively, the flue dust that pot galvanize produces extracts by these two slits.Because the flue dust temperature height that pot galvanize produces, lift velocity is very fast, so will collect zinc-plated flue dust preferably bigger draft must be arranged.The advantage of side exhausting system is: workpiece is hung less demanding, easy to operate; Collection effciency is generally about 75%; But this method institute required airflow is big, the power of motor height; The treatment capacity of follow-up purification apparatus is big; Zinc pot surface radiating is faster, is subjected to the workshop Influences on Wind Velocity bigger; Steel pole, steel pipe and similar tubular workpiece because flue dust can be emerged ease to zinc pot two ends in managing, can exceed the capture range of system; Can gather dust in the gathering system pipeline, need regularly to handle; Need more tubing system and accessory thereof etc.(2) mobile cover gathering system.Whole collection cover body is installed on the lifting machine, and can move with lifting machine.Cover body divides two portions, and top is fixing to be connected with lifting machine, and the bottom can move up and down.When workpiece was zinc-plated, the bottom cover body moved down zinc pot top is covered fully, and the flue dust of generation is collected to extract out in cover body and handles.After workpiece soaks the zinc certain hour, move on the cover body of bottom, reserve zinc pot top certain position, take off operations such as zinc gray with convenient zinc-plated workman.The advantage of mobile cover gathering system is: higher collection effciency can reach 95%; Institute's required airflow is half of side exhausting system, and power of motor is little; The treatment capacity of follow-up purification apparatus is little; The conduit system is simple; The danger that can avoid quick-fried zinc to bring to the operator, all on lifting machine, the weight that lifting machine is born needs bigger whole cover body weight, needs the higher lifting machine of tonnage but its shortcoming is; Zinc-plated inconvenient operation, the operating time is longer; Sealing member between each parts needs time-based maintenance; Cover on the lifting machine owing to will install and fix, zinc-plated region height need increase by 2～3 meters.(3) fixed cover gathering system.A big steel construction cover body is installed on the zinc pot, and workpiece will come out from the other end from entering along a section of the cover body of zinc pot length direction.Workpiece enters and carries out behind the cover body when zinc-plated, and the Men Jun of cover body both sides closes, to extract the flue dust of zinc-plated generation.The advantage of fixed cover gathering system is: surpass 95% collection effciency; Do not need to carry out the motion of large amount of complex, only need moving of door and window; All weight is all on ground, and lifting machine does not need to bear cover body weight; Provide excellent protection to zinc-plated workman; The treatment capacity of institute's required airflow and follow-up purification apparatus is little, and tubing system is simple etc., but its shortcoming is to drag for the slag difficulty; Zinc-plated operation inconvenience; The workshop is unsighted etc.
The flue dust that pot galvanize produces adopts the cloth bag type filtering system again flue dust to be carried out filtration treatment after gathering system is collected usually.Bag-type dust equipment manufacturing cost height, floor space is big, and the import of bag-type dust equipment also needs heating, drying etc.
