Embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is further described, but described in claimed scope is not limited to.
Reaction principle illustrates:
Clorox produce in cleaning time sodium pond waste liquid in sodium chloride-containing and available chlorine composition higher, sodium-chlor wherein be reclaimed, just must remove available chlorine composition wherein.
for reversible reaction
HClO-→H
++ClO
-
Dechlorination is destruction of balance relation, makes above-mentioned reaction towards generation Cl
2direction carry out.
Because the solubleness of chlorine in water is very little, when the dividing potential drop of solution surface chlorine is 101.3kPa, the solubleness in 70 DEG C of water is 0.0115mol/l, is equivalent to 0.4g/L.Observe Henry's law approx:
PCl
2＝KNCl
2
In formula: PCl
2---the dividing potential drop of the chlorine in gas phase;
The constant of K---measuring;
NCl
2---the mole number of the solute in solution.
The chlorine generated be separated out from solution, deacidification is outside one's consideration, and also ceaselessly will reduce the dividing potential drop of fluid surface chlorine, just can achieve the goal.In actually operating, add the acid of q.s, and make constantly produce bubble in Recycling of waste liquid or increase gas, liquid two phase-contact surface, accelerate gas phase flow velocity, strengthen degree of unbalancedness in gas-liquid two-phase, the dissolved chlorine in liquid phase is constantly shifted to gas phase, and gas is constantly overflowed.Carry out aforesaid operations continuously.Just the free chlorine in Recycling of waste liquid can be removed substantially.Owing to being adopt to destroy chemical equilibrium and the device that balances each other to remove free chlorine, therefore free chlorine can not absolutely remove.The free chlorine of remaining trace, makes it and oxidizing ClO with interpolation reducing substances
-reaction, thoroughly removes free chlorine.
