Simultaneously, because the electrolyte can be made by taking industrial coarse common salt as the raw material, the production cost is reduced, and besides, the device which has convenient operation, low cost but no pollution is suitable for being served as the special device used for the treatment of sewage discharge of industry, hospitals or other occasions.

Description

Sodium hypochlorite generator

The utility model relates to a kind of equipment for preparing clorox, specifically provides the electrolyze table salt electrolyzer of water generates clorox of a kind of utilization, the hypochlorite generator.

At present to the containing cyanogen, contain phenol and contain bacterium sewage and often adopt clorox to handle of discharges such as industry, hospital, and clorox often is to prepare by electrolytic saltwater.Existing hypochlorite generator utilizes diaphragm-free electrolysis salt method mostly, adopts square worn-out open type electrolyzer, multitube titanium anode, and rectifier power source adopts the self-coupling full-wave bridge rectifier circuit, and electrolytic solution salt solution refined salt is feedstock production.In addition, decompose for avoiding the clorox after the electrolysis, and set up water-chilling plant, to reduce electrolyzer temperature.This hypochlorite generator, electrolyzer has free chlorine to overflow, and promptly causes the pollution to air, also reduces clorox output.Simultaneously because the bottom of electrolytic tank settling easily causes inclined to one side road, consumed power not only, and easily produce heat and increase the electrolytic bath temperature, unfavorable clorox produces.Therefore, this equipment not only power consumption height, production cost height, waste a large amount of water coolants, and complex structure, equipment manufacturing cost height.

The purpose of this utility model provides a kind of hypochlorite generator, and it can avoid the various shortcomings of above-mentioned prior art, have simple in structure, power consumption is low, electrolytic efficiency is high, and air is not had any pollution.

The utility model has particularly carried out bigger improvement to electrolyzer and electrode to existing procucts, and takes other measure to achieve the above object.At first, adopt closed cylinder electrolyzer, can effectively avoid electrolysis to produce free the effusion, adopt the cartridge type positive and negative utmost point simultaneously, and dwindle pole plate width between centers, increased anode surface area like this, the utmost point water that makes electrolyzer is than improving.Thereby both improved electrolytic efficiency, increase anode life again.Secondly, bottom of electrolytic tank and electrode leave the gap with, and the precipitation glass of setting up a trapped dirt under electrolyzer looks handleless cup, can avoid deposit dirt in electrolyzer, the assurance electrolysis is effectively carried out.Because the electrolytic process settling can in time be discharged, therefore, dirt is little to the electrolytic efficiency influence in the electrolytic solution, can utilize the general industry crude salt for the feedstock production salt solution, has reduced productive expense.In the design of the present utility model cell construction is carried out reasonable configuration, rely on the electrolytic process electrolyte flow can reach the running balance of groove temperature, therefore can set up water cooling system, structure is further simplified at 35～40 ℃.In addition, this producer adopts bidirectional thyristor for regulating voltage and full-wave rectification formula rectifying circuit, has reduced the iron loss of varitran and copper loss and silicon rectifier cell forward voltage drop like this and has further reduced power consumption.Below by accompanying drawing structure of the present utility model is given to illustrate in further detail.

Accompanying drawing 1 is the utility model hypochlorite generator's a structural representation.Accompanying drawing 2 is its schematic circuit.Among the figure: 1, anode terminal; 2, discharge port; 3, cartridge type anode; 4, inner anode; 5, drum type brake electrolyzer (outer cathode); 6, inner cathode salt water hole; 7, lower flange and salt water hole; 8, foot rest; 9, salt water inlet; 10, precipitation glass is looked handleless cup; 11, insulating mat; 12, screw rod.D ₁Be bidirectional thyristor; D ₂, D ₃Be silicon diode, B is a supply transformer, and G is an electrode, and T is an electrolyzer.By the utility model hypochlorite generator shown in the accompanying drawing 1 is by electrolyzer, and electrode and rectifier power source are formed, and it is characterized in that electrolyzer adopts drum type brake closed electrolysis cells 5, and electrolyzer 5 is simultaneously as outer cathode; Anode adopts the cartridge type electrode, and the cartridge type anode is coaxial between two cartridge type negative electrodes, and anode has a segment distance from cell bottom.In addition, set up the precipitation glass of a sealing at electrolyzer 5 lower flanges for 7 times and look handleless cup 10, its external diameter is slightly smaller than the external diameter of electrolyzer 5, look handleless cup 10 sealings at the precipitated glass of lower flange and have salt water hole 7 on the contact surfaces, make by being installed in precipitation glass and look the salt water inlet 9 electrolytic solution salt solutions of handleless cup 10 bottoms and can enter in the electrolyzer 5.Can fall into precipitation glass by lower flange salt water hole 7 electrolytic process settlings simultaneously and look in the handleless cup 10, can very easily observe sedimental amount.When deposition is too much, can open the bottom that precipitation glass is looked handleless cup 10, will precipitate removing.By schematic circuit shown in the accompanying drawing 2, the utility model adopts bidirectional thyristor for regulating voltage full wave type rectified current.Its circuit layout is with reference to the very easy realization of known technology.

Hypochlorite generator shown in the accompanying drawing 1,2 can be used as an example of the present utility model.Lower flange 7 is fixed on the foot rest 8, to precipitate glass by screw rod 12 looks handleless cup and 10 is installed in lower flange 7 bottoms, electrolyzer (outer cathode) 5 and inner cathode 4 are installed on lower flange 7 tops, and with lower flange 7 excellent contact are arranged, lower flange 7 is derived end as negative electrode.With insulating mat 11 insulation the cartridge type anode is fixed in the electrolyzer 5 simultaneously.Electrolyzer all can be made by iron plate as outer cathode and inner cathode, and anode adopts titanium to be coated with the ruthenium anode.Circuit part can design with reference to prior art.During use, make with industrial crude salt and to feed salt water inlet 9 behind the certain density salt solution electrolyte filtering, charge into electrolyzer, inner cathode salt water hole 6 is passages of electrolytic solution.Connect the rectifying circuit power supply, the beginning electrolysis produces clorox in the electrolyzer, and control discharge port 2 flow velocitys keep electrolytic solution fully by electrolysis, can obtain the chlorine bleach liquor of certain content.

By upper example, utilize the utility model to have compared with the prior art following advantage:

1, the equipment power consumption is few, electrolytic efficiency is high, can fully save electric energy.

2, can use industrial refined salt electrolytic saltwater processed, clorox cost processed is descended, the electrolytic process deposit can be looked cup from precipitation glass and in time discharge.

3, adopt full-enclosed structure, do not have any free chlorine and overflow, free from environmental pollution.

4, do not use water coolant, simple in structure, easy to operate, equipment manufacturing cost is low, and electrode life is long.
