Description
Technical field
The utility model relates to a kind of clorox generating unit.
Background technology
The chlorine bleach liquor is a kind of safe, sterilizing agent and oxygenant efficiently, is widely used in the sterilization of hospital sewage, sanitary sewage, industrial circulating water, Drinking Water etc., also can be used for containing the processing of cyanogen trade effluent, has functions such as bleaching, decolouring, deodorizing.Existing clorox generating unit adopts water pump that salt solution directly is sent to electrolytic tank electrolysis more, and electrolytic solution is not just substituted by new salt solution when electrolytic process is also abundant, makes that the clorox concentration that produces is very low; Secondly, electrolysis tube in the existing clorox generating unit electrolyzer is generally the 8-10 root, because the electrolysis tube radical is many, the resistance that forms is big, electric current by the time heat that produces also big, to such an extent as to after the clorox generating unit used for some time, the anode surface coating of last two electrolysis tubes came off easily, cause that electrolytic efficiency is low, current consumption big, reduced the concentration of clorox.During the work of clorox generating unit, to produce the precipitation of hydroxide of metal ions such as calcium magnesium on the negative electrode of electrolyzer, these settlings are deposited on cathode surface, not only influence anodic electroconductibility, and can cause between the cathode and anode when serious and be short-circuited, consequently increased the power consumption of producing clorox, the productive rate that has reduced clorox.The method that solves cathode deposit has at present: (1) washes away cathode surface by swiftly flowing salt solution, prevents the negative electrode fouling, and this method scale removal is difficult for thoroughly; (2) electrode tube is taken apart, used the hydrochloric acid soaking and washing, dissolving has been deposited on settling on the negative electrode, and this method is very loaded down with trivial details, has not only increased workload, and clean, when installing accidentally, break the component of equipment easily; (3) adopt negative electrode commutation descaling method, promptly in electrolyzer, increase an auxiliary cathode, when needs are removed the main cathode surface deposits, the main cathode commutation is anode, auxiliary cathode is as negative electrode, and settling dissolving that just can it is surperficial when main cathode uses as anode is removed, though this method is easy to operate, but in the as easy as rolling off a log damage of practical middle-jiao yang, function of the spleen and stomach, scale removal also is difficult for thoroughly.And existing clorox generating unit electrolyzer is used the cathode material of stainless material as electrolysis tube more; corrosion can not take place in stainless material in the electrolytic process under the protection of cathode potential; but outage back stainless steel surface contacts with the chlorine bleach liquor corrosion can take place; have a strong impact on the work-ing life of stainless steel cathode; iron, the chromium plasma of the stripping of the process of corrosion simultaneously have contamination to electrolytic solution, have limited the range of application of clorox generating unit.
Summary of the invention
In order to overcome the deficiency of existing clorox generating unit, the utility model provide a kind of cleaning easily and thoroughly, the high clorox generating unit of clorox concentration produced.
Comprising of the utility model clorox generating unit salt device, high-order equilibrium box, water pump equilibrium box, tubular type electrolyzer and hydrochloric acid automatic flushing device, high-order equilibrium box is connected by water sprayer with the water pump equilibrium box, the tubular type electrolyzer is connected with high-order equilibrium box by advancing brine pipeline, the hydrochloric acid automatic flushing device by with advance the pipeline that brine pipeline communicates and be connected with electrolyzer, be provided with clear water back flushing pipeline in the device, this pipeline is connected with electrolyzer.Industrial Salt process in changing the salt device is dissolved, forms saturated saline solution and is removed the salt solution liquid-storing box in the inflowization salt device behind the suspended substance.The water pump equilibrium box is furnished with into water float(ing)valve, on the water pump output channel water sprayer is housed, in order to suction salt solution saturated solution.During starting mode of pump, water sprayer is under water-aspirator pressure, form vacuum, the salt solution saturated solution is picked up, a spinner-type flowmeter is installed on the suction tube of water sprayer, is controlled the lifting capacity of saturated saline solution, make it to mix the back proportioning and become required brine concentration with the water sprayer injection water, be sent to high-order equilibrium box, in the electrolysis tube of spinner-type flowmeter inflow tubular type electrolyzer, carry out electrolysis again.Owing to be equipped with the balance float(ing)valve in the high-order equilibrium box, it makes the flow of electrolyte that enters electrolysis tube keep balance, promptly when electrolytic process is insufficient in the electrolysis tube, salt solution in the high-order equilibrium box no longer flows in the electrolysis tube, when being discharged into liquid-storing box Deng the chlorine bleach liquor who produces after the electrolysis fully, the salt solution in the high-order equilibrium box just begins to flow in the electrolysis tube.This just makes salt solution fully electrolysis in electrolysis tube, and the clorox concentration of generation improves greatly.Electrolysis tube adds up to the 2-6 root in the electrolyzer, the resistance that produces is few, thereby current consumption is few, the top coat difficult drop-off of anode tube, guaranteed carrying out smoothly of electrolytic process, because the enlarged diameter of cathode and anode pipe, the tube spacing of cathode and anode pipe is from being 3mm, thereby the surface-area when having increased the electrolysis of solutions makes the chlorine bleach liquor that electrolytic solution still can the output higher concentration under the few situation of electrolysis tube radical.Be provided with clear water back flushing pipeline in the clorox generating unit; after every day, electrolytic process finished; open back flushing pipeline valve; the pvc pipe that washes electrolysis tube and be connected 10 minutes with electrolysis tube; can not only prevent that effectively dirt deposits in a large number in the electrolysis tube; and can protect the stainless steel cathode pipe, prolong the work-ing life of cathode tube.After clorox generating unit work 1-2 month, hydrochloric acid in the hydrochloric acid automatic flushing device is sent to by acid proof pump circulation and advances the pipeline that brine pipeline links to each other, clean electrolysis tube with hydrochloric acid and reach the pvc pipe that is connected with electrolysis tube, scavenging solution is got back to again in the hydrochloric acid automatic flushing device, and the time only needs 20 minutes.
Adopt the utility model to produce clorox, the production whole process can be carried out automatically, adopts high-order equilibrium box to control the balance electrolysis, makes electrolytic process abundant, the clorox concentration height of generation; The electrolysis tube radical mostly is 6 most in the electrolyzer, and current consumption is few; Be provided with clear water back flushing pipeline and hydrochloric acid automatic flushing device, it is convenient to clean, and has prolonged the work-ing life of electrolysis tube.With the clorox generating unit of chlorine yield 500g per hour is example, and through Fujian Province Central Inspect Station's check, index is as follows:
| Interventions Requested | National standard | Assay |
| 1. direct current consumption | ≤7.0kWh/kg | ?4.2kWh/kg |
