Abstract
The utility model discloses a waste gas treatment device for a hot dip galvanizing process of a road member. The waste gas treatment device comprises a smoke removal tower and a fan, wherein a water inlet and a water outlet are arranged on the smoke removal tower; a spray nozzle is arranged at the upper part inside the smoke removal tower; a collecting tank is arranged at the lower part inside the smoke removal tower; the water inlet is connected with the spray nozzle; the water outlet is connected with the collecting tank; an exhaust chimney is arranged at the top of the smoke removal tower; a ventilating pipeline of which an opening is formed above an activating pool is arranged at the lower part of the smoke removal tower; the fan is arranged on the ventilating pipeline. After the waste gas treatment device is adopted, emission of the waste gas is less; no smoke is generated; normal life of nearby residents is not affected; the environmental requirements are met.
Description
Technical field
The utility model relates to a kind of hot dip galvanizing process, specifically a kind of emission-control equipment of the hot dip galvanizing process for road component.
Background technology
Galvanizing also claims galvanizing by dipping, is that steel component immerses a kind of method that obtains metal cladding in the zinc liquid of melting.Along with high voltage power transmission, traffic, communication career develop rapidly, more and more higher to the steel and iron parts requirement of shelter, the galvanizing demand also constantly increases.
Traditional hot dip galvanizing process process is: workpiece → degreasing → washing → pickling → wash → soak helps plating solvent → drying and forewarm → galvanizing → arrangement → cooling → rinsing → drying → check.Wherein, soak fluxing agent and can remain on before immersion plating workpiece and have certain activity and avoid secondary oxidation, be combined with matrix to strengthen coating, fluxing agent also claims solvent, can remain on before immersion plating workpiece and have certain activity and avoid secondary oxidation, is combined with matrix with enhancing coating.Drying and forewarm be for prevent workpiece when the immersion plating because temperature sharply raises and is out of shape, and remove residual moisture, prevent quick-fried zinc, cause that zinc liquid is quick-fried to be spattered, preheating is generally 80～140 ℃.During galvanizing, to control zinc liquid temperature, immersion plating time and the speed of workpiece from drawing zinc liquid well.The speed of drawing is generally 1.5 meters/min.Temperature is too low, zinc liquid poor fluidity, and coating is thick and inhomogeneous, easily produces sagging, and presentation quality is poor; Temperature is high, zinc liquid good fluidity, and zinc liquid easily breaks away from workpiece, and reduce sagging and elephant skin phenomenon and occur, strong adhesion, coating is thin, and outward appearance is good, and production efficiency is high; But excess Temperature, workpiece and zinc pot iron loss are serious, produce a large amount of cadmias, affect the zinc-impregnating layer quality and easily cause aberration to make surface color ugly, and the zinc consumption is high.Zinc coating thickness depends on zinc liquid temperature, galvanizing time, steel material and zinc liquid composition.General producer, in order to prevent the workpiece high temperature deformation and to reduce because iron loss causes cadmia, all adopts 450～470 ℃, 0.5～1.5min.Arrangement is that after plating, arrangement is mainly to remove the remaining zinc in surface and list edge to workpiece, with adopting galvanizing special use electromagnetic shaker to complete.When cooling, generally use water-cooled, but temperature can not be too low also can not be too high, generally be not less than 30 ℃ not higher than 70 ℃.The shortcoming of this hot dip galvanizing process is: in pickling with soak and help the plating solvent when (activation), toxic emission is serious, has affected near resident normal life, does not meet environmental requirement.
Summary of the invention
The problem existed in order to overcome prior art, the purpose of this utility model is to provide a kind of emission-control equipment of the hot dip galvanizing process for road component, adopt this emission-control equipment after toxic emission few, there is no smog, near not affecting, resident's normal life, do not meet environmental requirement.
The purpose of this utility model is achieved through the following technical solutions:
A kind of emission-control equipment of the hot dip galvanizing process for road component, it is characterized in that: emission-control equipment comprises smoke abatement tower and blower fan, on the smoke abatement tower, be provided with water inlet and delivery port, be provided with water fog applicator at smoke abatement tower internal upper part, bottom is provided with collecting-tank in the smoke abatement tower; Water inlet is connected with water fog applicator, and delivery port is connected with collecting-tank; At the smoke abatement top of tower, be provided with exhaust chimney; In smoke abatement tower bottom, be provided with opening and be positioned at the ventilation shaft above activating tank, blower fan is arranged on ventilation shaft.
In the utility model, water fog applicator is arranged on smoke abatement tower internal upper part zone line.Water fog applicator is circular shower nozzle.Delivery port is connected with the import of water treatment facilities by pipeline, and the outlet of water treatment facilities is connected with water inlet by pipeline.
In the utility model, emission-control equipment collects the flue gas produced in activating tank, and will discharge through the waste gas that water smoke purifies by exhaust chimney, pollutes littlely, does not affect near resident normal life, does not meet environmental requirement.Waste water can recycle by water treatment facilities simultaneously, energy-conserving and environment-protective.
Adopt the utility model to make the hot dip galvanizing process energy-conserving and environment-protective, toxic emission meets the requirements, and reduces the impact on surrounding environment.
The utility model is applicable in the hot dip galvanizing process of the road components such as scaffold, electric pole.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
A kind of emission-control equipment of the hot dip galvanizing process for road component, see Fig. 1, emission-control equipment comprises smoke abatement tower 11 and blower fan 12, on the smoke abatement tower, be provided with water inlet 13 and delivery port 14, at smoke abatement tower internal upper part, be provided with water fog applicator 15, water fog applicator is arranged on smoke abatement tower internal upper part zone line, and water fog applicator is circular shower nozzle.Bottom is provided with collecting-tank 16 in the smoke abatement tower; Water inlet is connected with water fog applicator, and delivery port is connected with collecting-tank; At the smoke abatement top of tower, be provided with exhaust chimney 17; In smoke abatement tower bottom, be provided with opening 19 and be positioned at the ventilation shaft 18 above activating tank 3, blower fan is arranged on ventilation shaft.Delivery port is connected with the import of water treatment facilities by pipeline, and the outlet of water treatment facilities is connected with water inlet by pipeline, and waste water can recycle by water treatment facilities, energy-conserving and environment-protective.
The utility model collects the flue gas produced in activating tank, and will discharge through the waste gas that water smoke purifies by exhaust chimney, pollutes littlely, does not affect near resident normal life, does not meet environmental requirement.
