Description
Technical field
The present invention relates to chemical technology field more particularly to a kind of methods for removing chlorine in high zinc solution containing sulfuric chlorohydrin.
Background technique
Currently, the removing process of chlorine is common in common solution of zinc sulfate: silver nitride precipitation method plus alkali neutralization sink zinc method and
Chlorine removal from copper residue method.Wherein, silver nitride precipitation method is that silver salt is added in solution of zinc sulfate, generates chlorination with the chloride ion in solution
Silver precipitating, to remove chloride ion.This method is at high cost, is worth without production application.It is molten in zinc sulfate for adding the heavy zinc method of alkali neutralization
Alkali, such as sodium hydroxide, sodium carbonate, sodium bicarbonate, ammonium hydroxide, ammonium carbonate are added in liquid, zinc is made to generate hydroxide or complex compound,
It is precipitated out from solution, to remove chloride ion.This method is at high cost, and zinc recovery is low, and the wastewater flow rate being discharged is big, pollutes ring
Border.Chlorine removal from copper residue method is to react to generate stannous chloride precipitating with chloride ion in solution of zinc sulfate using cuprous ion, from solution
Remove chloride ion.Such as the patent of invention of Patent No. 200810058431.8, handled solution is electrolytic zinc neutrality leachate,
Cu2The inventory mass ratio of O controls Cu+/C1-=1.5~3, this method haves the defects that process is cumbersome and dechlorination rate is low.
Summary of the invention
The technical problem to be solved by the present invention is overcoming the deficiencies of the prior art and provide, a kind of industrial flow is simple, cost
The method of chlorine in the high zinc solution containing sulfuric chlorohydrin of removal low, that dechlorination rate is high.
The technical solution adopted by the present invention to solve the technical problems is: chlorine in a kind of high zinc solution containing sulfuric chlorohydrin of removal
Method, the chloride ion made a return journey in sulfuric acid zinc solution using the concentrated sulfuric acid as reactant；Specific step is as follows:
(1) high zinc solution containing sulfuric chlorohydrin is added in reactor tank；
(2) reactor tank is warming up to 100~150 DEG C；
(3) concentrated sulfuric acid is slowly added into reactor tank while stirring；
(4) gas generated in reactor tank is led in tourie；
(5) solution of zinc sulfate for removing chloride ion is entered into subsequent processing purifying regeneration after reaction and produces zinc series of products；
Further, the weight ratio of the high zinc containing sulfuric chlorohydrin and the concentrated sulfuric acid is 1:2 ~ 4.
Further, it is slowly added in the step (3) time many 3 hours of the concentrated sulfuric acid.
Further, the reaction time is 4 ~ 6 hours.
Further, the liquid in the step (4) in tourie is water.
Beneficial effects of the present invention: a kind of method for removing chlorine in high zinc solution containing sulfuric chlorohydrin of the present invention, by reaction
The concentrated sulfuric acid is slowly added in tank while stirring, while the hydrogen chloride gas of generation is led into tourie in time, to realize
The purpose of chloride ion in efficient removal solution of zinc sulfate, the present invention, process flow is simple, and dechlorination rate is high, reaches 95% or more,
And it is at low cost, the hydrochloric acid of the formation in tourie can be recycled in industrial production, economic and environment-friendly.
Specific embodiment
A method of chlorine in high zinc solution containing sulfuric chlorohydrin is removed, is made a return journey sulfuric acid zinc solution using the concentrated sulfuric acid as reactant
In chloride ion, be added according to the weight ratio of height zinc containing sulfuric chlorohydrin and the concentrated sulfuric acid for 1:4, the specific steps are as follows:
(1) high zinc solution containing sulfuric chlorohydrin is added in reactor tank；
(2) reactor tank is warming up to 100 DEG C；
(3) concentrated sulfuric acid is slowly added into reactor tank while stirring, is slowly added to many 3 hours of the time of the concentrated sulfuric acid；
(4) gas generated in reactor tank is drawn by exhaust fan, is led in tourie through conduit, absorbing liquid in tourie
For water；
(5) reaction carries out 6 hours, and the solution of zinc sulfate for removing chloride ion is entered subsequent processing purifying regeneration after reaction and is produced
Zinc series of products；
The working principle of the invention and application method: a kind of method for removing chlorine in high zinc solution containing sulfuric chlorohydrin of the present invention uses
The concentrated sulfuric acid is made a return journey the chloride ion in sulfuric acid zinc solution as reactant, by the way that dense sulphur is slowly added while stirring into reactor tank
Acid, while the hydrogen chloride gas of generation is led into tourie in time, thus realize in efficiently removal solution of zinc sulfate chlorine from
The purpose of son.Its key reaction principle is as follows:
(dense) H2SO4+ Zn Cl 2 ZnSO4 + HCl
By the way that the concentrated sulfuric acid is slowly added while stirring, while the hydrogen chloride of generation is drawn into reactor tank in time, according to Le Xiate
Column principle constantly generates hydrogen chloride, removes the chlorine in solution of zinc sulfate, chlorine goes dechlorination can it is found that reaction will carry out to the right
Up to 95% or more.In addition, the hydrogen chloride led in tourie, which is only absorbed by the water generation hydrochloric acid, to be recycled in industrial production,
It is economic and environment-friendly.
