Description
Technical field
The utility model relates to the not water-saving strip pickling line of pump drainage acid mist of recyclable hydrogen, belongs to strip pickling manufacturing field of equipment.
Background technology
At present, use conventional hot rolled strip carry out for raw material cold rolling before, generally all must carry out scale removal operation.Conventional thicker oxide skin removal method now, general technology is that first alternating bending makes oxide skin part peel off or loosen, and then pickling; Or adopt again mechanical means.
When pickling, more oxide skin is to react by acid the hydrogen generating with base steel to peel off, so it is effective to descale, is the method that cold rolled strip industry is generally used so far.The process characteristic of acid wash, acid need be warmed to 70 degrees Celsius of left and right (depending on acids), and pickling effect is good.But, increased thus the generation of acid mist.What strip pickling production line was conventional now is roller press type technique, and acid tank respectively has a stone roll in end; Above stone roll, there is forward and backward cover; Each exhaust equipment of installing above forward and backward cover; Acid tank section principal piece, between front and back covers, employing is added a cover, and water is inserted on lid limit, escapes with water seal acid-mist; As band steel passage, import and export are open, or hang the many soft curtains of moulding of formula; Be to rely on the negative pressure forming in the pressure difference of this region and atmosphere into and out of the flow of end vacuum fan exhausting, acid mist suction treating column is further processed, acid mist is not leaked.Follow chemical pickling, have hydrogen to produce, prior art is all that outer row does not reclaim.Band steel out enters open space afterwards from acid tank, is introduced into residual sour operation; Then pass through modified roller assembly, the function of this assembly is by spacing band steel, raise, and in residual sour backflow acid tank, be then that water rinses operation.Enter subsequently Rinsing Area and clean, go out Rinsing Area through modified roller, enter passivation procedure, after purifying, pickling process finishes.More than existing with pickling line conventional equipment and conventional process flow.
Background technology strip pickling line weak point is: the one, and be generally by configuring high-power vacuum fan, the acid mist of generation all can be aspirated in theory, but, importing and exporting cross section each point, the negative pressure forming while work with the vacuum fan with the T-shaped installation of steel direct of travel is discrepant, is in fact difficult for avoiding acid mist to overflow; It is many that high-power vacuum fan consumes sour power consumption, and production cost is higher; At present to escape that acid mist pollutes atmosphere be compared with Universal Problems to strip pickling; The 2nd, acid mist is the gaseous form of acid solution, is waste acid solution by its suction; Vacuum fan power consumption, acid mist treatment tower power consumption, consumptive material, water consumption, acid mist treatment tower also has secondary pollution problem; The 3rd, the hydrogen that the pickling chemical reaction of considerable amount is generated directly enters atmosphere, causes energy dissipation; And hydrogen be suitable for the heat treated protective atmosphere of steel or can be used for the high-grade energy of acid solution heating etc.; The 4th, adopt extensive style drip washing, water consumption is large; Need the water yield of environmental protection treatment many.It is worth mentioning, overflow type pickling has been applied to wire acid cleaning, and acid-mist structure is that one section of the each extension of acid tank in-out end adopts water curtain type water seal.Wire rod and the comparison of band steel, have single wire rod sectional area little, easily exceptionally straight, can entirely be immersed in overflow acid, can side lead-in wire, residual acid is easily let out under cascade between dirty, line can be by the exclusive feature of wire rod into and out of the basic full water seal of end section, it is better that acid-mist escapes effect; Pickling tank Length Ratio is shorter.And band steel does not possess These characteristics, should not adopt overflow type pickling.Existing wire rod overflow type underpickling part is: the one, and an acid solution part for condensation flows into water sealed tank, and the part that acid mist is a considerable number of and cascade are fused, are unfavorable for saving acid water saving; The 2nd, hydrogen is not recycled, and this is also unfavorable for acid mist condensation,
