Description
Technical field
The present invention relates to disinfection water treatment fields more particularly to a kind of hypochlorite, and method is prepared in situ.
Background technology
With constantly contaminated and water resource the continuous shortage of water resource on the earth, disinfection water process seems more and more heavier
It wants；Cholorination is current the most widely used water sterilization method, is played an important role in terms of pre- waterproof spreads the disease.
Cholorination mainly adds chlorine or hypochlorite (such as NaClO) into water, can generally generate hypochlorous acid (HClO) and hydrochloric acid
(HCl).The approach for obtaining liquor natrii hypochloritis at present mainly has chlor-alkali plant to manufacture and be prepared in situ, and the secondary chlorine of chlor-alkali plant manufacture
Available chlorine content is 10% or so in acid sodium solution, however lot of experimental data shows the liquor natrii hypochloritis of high concentration easily
It decomposes, daily decomposition amount has reached 0.4mg/L-0.7mg/L, caused the great wasting of resources；Meanwhile high concentration hypochlorous acid
Sodium solution belongs to dangerous material as chlorine, and transport and preservation cost are quite high, and there are great security risks.Sodium hypochlorite is sent out
Raw device generates the sodium hypochlorite solution of low concentration, its Disinfection Effect is good, and it is accurate to add, and safe operation is easy to use, easily stored,
To environment nonhazardous, second of pollution is not generated, and there is advantage very much.
Currently, sodium hypochlorite preparation system in market there are effective chlorine densities unstable, power consumption and salt consumption is excessively high, operation
The problems such as cost is larger, production system stability is poor.The patent of Patent No. CN201210334192.0《A kind of electrolytic
Sodium chlorate generating system》Provide a kind of method for electrolysis production liquor natrii hypochloritis, but the sodium hypochlorite of the invention
The saline solution of solution production system becomes with environment temperature, is unable to control the stability of production system；It is too low to enter coolant-temperature gage, slot
Voltage necessarily increases, and power consumption increases；It is excessively high to enter coolant-temperature gage, electrolytic cell leaving water temperature is more than 40 DEG C, and liquor natrii hypochloritis easily divides
Solution, and plastic items are easy aging in electrolytic cell.

Further, in electrolysis step, air blower is used to be reduced to its volumetric concentration to be limited for 4% safety density of hydrogen
It is discharged under degree.
The beneficial effects of the present invention are：
The hypochlorite of the present invention is prepared in situ method, first, by for produce the tap water of liquor natrii hypochloritis into
Row sofening treatment removes Ca, Mg plasma in water removal, prevents electrode fouling in electrolytic process, current efficiency from declining, has ensured life
The stability of production system；Secondly, the softened water after saturated salt solution and sofening treatment in dissolved salt tank by flowmeter in proportion
Mixing adjusts brine strength in 1.5%-2.5%, is 0.8% by the liquor natrii hypochloritis's effective chlorine density generated after electrolysis
More than, therefore, system operation salt consumption is very low；Again, electrolytic cell will be entered using heater/cooler in production system
Brine and softening coolant-temperature gage control within the scope of best electrolysis temperature, avoid temperature too low or it is excessively high to current efficiency reduce,
The increased influence of operation energy consumption ensures sodium hypochlorite production system stable operation；In short, the preparation method solves the prior art
Middle sodium hypochlorite preparation system there are effective chlorine densities unstable, power consumption and salt consumption are excessively high, operating cost is larger, production system is steady
The qualitative technical problems such as poor.
