Description
Technical field
The invention belongs to the Recycle Technology of Waste Water fields of metal finish, and in particular to a kind of acid recovery of pickle liquor and
Purification system.
Background technique
Strong inorganic acid (sulfuric acid, nitric acid, hydrochloric acid etc.) is commonly used in metal finish industry to remove the oxidation of metal surface
Object is to reduce its influence to subsequent production operation.Largely, these oxide epidermises be by acid dissolution, and with
Be dissolved in the increase of metal concentration in acid solution, the concentration of free acid is also accordingly reduced.Although new acid can be added into acid
To make up this disadvantage in liquid, but when metal concentration increases, oxide removal efficiency (pickling ability) would generally be reduced.
When oxide skin can not be sufficiently removed again, these acid solutions must just be disposed the acid solution more renewed.
This operating method can reduce production efficiency.And the pickling ability for the acid solution newly prepared is very powerful, and can
It can lead to over-pickling, therefore generate material may also be able to close to underproof phenomenon in turn is scrapped due to pickling.In order to
Subsequent process of surface treatment problem is prevented, doing over again may be necessary.
In addition, also containing a large amount of not used or " free " acid with the pickling solution to have given up, valuable chemicals does not have
It is recovered, while also will increase the difficulty of wastewater treatment.Therefore, it is badly in need of a kind of clearing machine recovery process of novel effective acid.
In the prior art, the apparatus structure for acid block technique of use is more complicated, takes up a large area, there is also trees
The problems such as rouge is easily contaminated and scraps, the rate of recovery of acid is low, recovery acid impurity is more, recycling acid concentration is low, the recycling of spent acid
Treatment effect is poor.
Such as application No. is 201710629752.8 Chinese invention patents to disclose a kind of waste acidity recovery method and apparatus, side
Method is that spent acid is carried out sour absorption into equipped with the resin tank body for inhaling acid resin through pumping pressurization into acid after filtering, unadsorbed
The waste water of saliferous drain into wastewater collection pond through water outlet；The resin tank body height≤500mm, the resin filled are spherical
Particulate resin.Method provided by the invention is with the obvious advantage in terms of waste acidity recovery, has occupied area small, easy to operate, acid recovery
For rate 95%, recovery acid concentrations versus has a degree of concentration in former spent acid free acid concentration, and spent acid free acid concentration exists
The pure acid that 10%~15% concentration obtains can be concentrated to 20%~30%, the metal salt residual quantity of the pure acid of gained 1 gram/
It rises hereinafter, the application of enterprise can be met.
For another example application No. is 201621013666.1 Chinese utility model patent, to disclose a kind of Special Resin trundle bed useless
Acid-restoring plant, including ion exchange column, waste acid pot, elution flow container, brine tank, sour collecting tank and eluent recycling can, ion
The top of exchange column is equipped with eluent import and brine outlet, bottom is equipped with spent acid import and eluent exports, waste acid pot and useless
The first booster pump, first flowmeter, first filter, the first valve, elution flow container and eluent import are equipped between sour import
Between be equipped with the second booster pump, second flowmeter, the second filter, the second valve, between brine outlet and brine tank be equipped with PH
Detector, third valve, sour collecting tank and eluent outlet between be equipped with H+ detector and the 4th valve, eluent recycling can with
The connection of eluent inlet ductwork.The purpose is to: solve existing acid-restoring plant there are structures more complicated, water consumption compared with
Greatly, the poor problem of the recovery processing effect of spent acid.
