Detailed Description
The following are embodiments of the present invention and the accompanying drawings are used to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.
A sodium hypochlorite generator, as shown in figure 1: comprises a mounting rack 10, a power supply 20 arranged on the mounting rack 10, a plurality of electrolytic bath assemblies 30 connected with the power supply 20 in series, a saline pipe 41 connected with the electrolytic bath assemblies 30, a water inlet pipe 42 and an acid inlet pipe 43; the electrolytic cell component 30 comprises a mounting groove 31 provided with an inlet and an outlet, a plurality of electrode groups 32 arranged in the mounting groove 31 and heat exchange components 33, wherein a water inlet pipe 42 is connected in series with the heat exchange components 33 of the electrolytic cell component 30; the brine pipe 41, the water inlet pipe 42 and the acid inlet pipe 43 are connected in series with the mounting grooves 31 of the plurality of electrolytic bath assemblies 30 through the same series structure, and the outlet of the uppermost electrolytic bath assembly 30 is also connected with a liquid outlet pipe 44.
When the electrolytic cell is used, the brine pipe 41 is opened to sequentially introduce dilute brine into the electrolytic cell assembly 30, the power supply 20 is turned on to electrify the electrode assembly 32, sodium chloride and water in the dilute brine are ionized, hydrogen and chlorine are respectively generated at the cathode and the anode, and the remaining hydroxide ions are combined with the sodium ions to generate sodium hydroxide. After being dissolved in water, chlorine reacts with sodium hydroxide to generate sodium chloride and sodium hypochlorite. And the chloride ions in the water also react with the sodium hydroxide to generate sodium chloride and sodium hypochlorite, and the obtained sodium hypochlorite is discharged from the liquid outlet pipe 44 in sequence under the action of the pump. During electrolysis, the joint between the water inlet pipe 42 and the heat exchange member 33 needs to be opened to continuously cool the electrolyzer assembly 30. After the electrolysis is finished, the connecting parts of the acid inlet pipe 43, the water inlet pipe 42 and the mounting groove 31 are sequentially opened to sequentially perform acidity and washing on the mounting groove 31, namely, the problem of the electrolysis environment temperature is solved through the heat exchange piece 33, and the problem of electrolysis scaling is solved through the water inlet pipe 42 and the acid inlet pipe 43.
As shown in fig. 3, a mounting plate is arranged at the end of the mounting groove 31, and the heat exchange member 33 is suspended above the notch of the mounting groove 31 through the mounting plate; the water inlet end and the water outlet end of the heat exchange member 33 are disposed on the same mounting plate, so that the circulating cooling water is continuously supplied to the heat exchange member 33. The heat generated by electrolysis rises along the gaps between the electrode groups 32, and is taken away by the heat exchange member 33 after contacting the heat exchange member 33 through which the circulating cooling water is passed.
In order to improve the heat exchange effect, the heat exchange element 33 is designed as a TA2 titanium tube with the outer wall coated with phenolic resin. Compare in traditional stainless steel construction, the heat exchange tube wall thickness of its preparation is thinner, can greatly improve heat exchange efficiency. Simultaneously titanium still has intensity height, light in weight's characteristics, because hang the titanium pipe in mounting groove 31 notch top in this embodiment, the effect is established in the suspension can reach better to lighter titanium pipe to it is sealed when being favorable to the installation.
Since the passivation potential of titanium is more negative than the standard electrode potential of hydrogen in most media, even in the presence of oxygen, which is important in non-oxidizing acids such as hydrochloric acid and sulfuric acid, titanium can be passivated. After a period of electrolysis, the electrolytic cell assembly is subjected to acid pickling for descaling, which easily causes the passivation of titanium, so that a thicker passivation film is formed on the surface of the heat exchange member 33, and although the corrosion resistance of the titanium pipe is increased, the heat exchange efficiency is affected. Therefore, the phenolic resin coating is coated on the surface of the titanium pipe, passivation of titanium can be prevented, corrosion of the heat exchange piece 33 can be prevented, and the phenolic resin hardly influences heat exchange.
The heat exchange effect is improved from the aspect of material improvement, and the heat exchange effect can also be improved from the aspect of structure improvement.
The body of the heat exchanging member 33 can be bent several times to form several heat exchanging parts, so that the contact area between the hot gas and the heat exchanging member 33 is increased to improve the heat exchanging effect. As shown in fig. 4, a plurality of protrusions 33a may be annularly formed on the outer surface of the heat exchanger 33, a recess 33b may be formed between the protrusions 33a, and a honeycomb groove formed by a plurality of regular hexagonal grooves may be formed on the outer wall of the protrusion 33 a. On one hand, the heat exchange area of the heat exchange piece 33 is further enlarged through the concave-convex structure and the honeycomb grooves; on the other hand, the honeycomb grooves 33a are an ideal heat dissipation structure in addition to having good specific rigidity and specific strength. Meanwhile, the hot gas generates turbulent flow with strong impact continuously with the outer wall of the heat exchange member 33 in the structural gap. Because the dilute brine may contain impurities and sodium hydroxide is generated in the electrolysis process, part of the impurities and the sodium hydroxide continuously contact the heat exchange member 33 along with hot gas and are attached to the heat exchange member 33 to damage the impurities and the sodium hydroxide, the contact area between the subsequent hot gas and the heat exchange member 33 can be reduced, and the heat exchange effect of the heat exchange member 33 is influenced, so that the surface of the heat exchange member 33 can be continuously impacted by the impact turbulence effect to reduce the attachment of scale.
In addition, because the cooling water entering the heat exchange member 33 is not pure water, impurities in the water easily form scales on the inner wall of the heat exchange member 33, and the scales are inconvenient to clean, an elastic descaling ball is arranged in the heat exchange member 33, and when the water is introduced into the heat exchange member 33, the water flow drives the elastic descaling ball to impact the inner wall of the heat exchange member 33 to descale.
Since the heat exchange member 33 is suspended above the notch of the installation groove 10, there may be a problem in that the installation is unstable. Therefore, the heat exchanger further comprises a fixing part 34 which is sleeved on the mounting groove 31 and used for fixing the suspended part of the heat exchange part 33, wherein the fixing part 34 comprises a bearing part used for bearing the heat exchange part 33 and a tightening part used for tightening the heat exchange part 33, and the bearing part is provided with a bearing groove. The heat exchange member 33 is surrounded by the bearing part and the clamping part, and the mounting groove 31 and the heat exchange member 33 are surrounded by the fixing part 34, so that the stability of the heat exchange member 33 is kept, and the problems that the heat exchange member 33 sinks downwards in the notch of the mounting groove 31 or tilts upwards and the like are solved.
The electrolysis of dilute brine is accomplished by the electrode assembly 32, and therefore the design of the electrode assembly 32 is also important. As shown in fig. 2, the electrode group 32 includes an anode electrode 32a connected to a positive power supply electrode, a cathode electrode 32b connected to a negative power supply electrode, and an intermediate inductive electrode 32c, and the intermediate inductive electrode 32c includes an inductive cathode portion adjacent to the anode electrode 32a and an inductive anode portion adjacent to the cathode electrode 32 b.
The electrodes are parallel to each other and have a certain gap, and when dilute brine is introduced into the mounting groove 31, the electrodes are conducted. Although the middle inductive electrode 32c is not directly connected to the power supply, its two ends are respectively charged with positive charges and negative charges under the action of the induced charge principle, so that the current flows from the positive electrode to the negative electrode, sequentially passes through the anode electrode 32a, the inductive cathode portion, the inductive anode portion, and the cathode electrode 32b to form a loop, and the electrodes are connected in series. According to the voltage division principle of the series circuit, the current can be reduced in multiples according to the number of the electrodes connected in series, so that the current and the heat generated during electrode electrolysis can be reduced to a great extent, and the potential safety hazard problem caused by heat generation during electrolysis is further reduced.
In addition, the anode electrode 32a and the cathode electrode 32b are respectively disposed on the mounting plate through a wire connecting member 32e, and the wire connecting member 32e includes a connecting plate provided with a plurality of grooves for receiving ends of the anode electrode 32a or the cathode electrode 32b and a wire connecting head penetrating the mounting plate to be connected to a power source, thereby sequentially mounting the electrodes in the mounting groove 31. And in order to reduce the self resistance heating problem of the wiring piece 40 and ensure the conductive effect, the material of the wiring piece 40 adopts titanium copper alloy.
Meanwhile, the intermediate inductive electrode 32c is not directly connected and fixed to the mounting groove 31, but the anode electrode 32a and the inductive cathode portion, and the cathode electrode 32b and the inductive anode portion are connected by a connection rod 32d, respectively. The material of the connecting rod 32d should be insulating, so in the embodiment, a plastic connecting rod is selected.
After the electrolysis finishes, when carrying out the pickling and washing to mounting groove 31, and only make acidizing fluid or rivers through mounting groove 31, can not wash mounting groove 31 well, all be equipped with ultrasonic oscillator in consequently the tandem structure, because the propagation distance of ultrasonic wave in aquatic is far away, the ultrasonic oscillator in consequently the tandem structure can drive the liquid vibration descaling in the electrolysis cell subassembly 30.
In order to further enhance the descaling effect of the water flow and the acid flow, a pressure pump can be arranged at the communication part of the serial pipe structure and the electrolytic bath assembly 30, so that the acid liquid and the water enter the electrolytic bath assembly 30 at a certain speed and collide with the electrodes and the inner wall of the electrolytic bath for descaling.
It should be further noted that the side reactions are likely to occur during the electrolysis process, and since dilute brine (3 wt%) is used in this embodiment, the most likely side reaction is the formation of oxygen at the anode, which can oxidize and damage the coating of the anode, resulting in a reduced enhanced lifetime. Therefore, the surface of the anode electrode 32a is provided with the high-oxygen ultra-nanocrystalline titanium coating.
During electrolysis, the anode adopts a high-oxygen ultra-nanocrystalline titanium coating, so that the chlorine evolution potential is reduced to 1.124; the incidence of oxygen evolution side reactions is significantly reduced. And the strengthening service life is prolonged to more than 280 h.
In this example, the high-oxygen ultra-nanocrystalline titanium coating was produced by the following method:
(a) treating the titanium substrate, namely performing sand blasting, acid washing, deionized water washing and drying on the titanium substrate;
(b) dispersing graphene oxide and a silane coupling agent KH-550 in n-butyl alcohol to prepare a graphene oxide dispersion solution for later use; dispersing ruthenium trichloride, tantalum pentachloride, chloroiridic acid and butyl titanate in n-butyl alcohol to prepare high-oxygen ultra-nano anode coating dispersion liquid for later use;
(c) coating graphene oxide dispersion liquid on a titanium substrate, and drying at 95 ℃; then brushing high-oxygen ultra-nano anode coating dispersion liquid, and drying at 95 ℃; then, sintering for 15min at 470 ℃;
(d) and (3) after cooling, repeating the step (c) for 25 times, and finally sintering for 50 min.
Wherein the mass ratio of the ruthenium trichloride, the tantalum pentachloride, the chloroiridic acid and the butyl titanate is 6:10: 3:40 in terms of the atomic mass of the ruthenium, the tantalum, the iridium and the titanium. The amount of graphene used to form the graphene dispersion was 0.4 g/L. The total metal ion concentration of the high-oxygen ultra-nano anode coating dispersion liquid is 0.25 mol/L.
The coating is subjected to an enhanced life test, wherein the enhanced life test is a rapid life test method of anode electrolysis in sulfuric acid solution at high current density, and the service lives of different electrodes are compared by testing the failure time of an electrode enhanced life test of different tested anodes working at the same current density in sulfuric acid solution with the same concentration and temperature.
The specific operation is as follows:
(1) hydrochloric acid with the mass concentration of 1mol/L is taken as electrolyte, a titanium substrate with the high-oxygen ultra-nanocrystalline titanium coating is taken as a working anode, and the titanium substrate is fixedly installed and completely submerges the effective working part of a cathode and an anode;
(2) after the temperature of the electrolyte rises to 40 +/-1 ℃, switching on a power supply and adjusting the electrolytic current density to 200A/dm2And maintaining the same constant during the test, adding a certain amount of distilled water and H occasionally during the electrolysis2SO4To maintain the electrolyte level and concentration;
(3) recording the electrolysis time, the electrolysis current and the voltage value of the electrolytic cell every half hour;
(4) stopping the test when the voltage of the electrolytic bath begins to rapidly and greatly rise;
(5) the cumulative electrolysis time from the start of the experiment to the time when the cell voltage rises greatly is referred to as the life-strengthening test failure time of the electrode under test. The area of the electrode in this test was 10.0cm2
The coating was tested for chlorine evolution potential according to 7.5 of HG/T2471-2011.
The results are as follows:
in the above scheme of the utility model, the ruthenium trichloride, the tantalum pentachloride, the chloroiridic acid and the butyl titanate all form metal oxides after sintering; wherein, the metal oxides of ruthenium and iridium are conductive components, and the metal oxides of titanium and tantalum are non-conductive components; the coating is added with non-conductive components, so that the conductive components tend to be stable; the coating can remarkably relieve the passivation speed of the titanium-based metal plate.
Butyl titanate is present as a binder, is an unavoidable component to allow the coating liquid to firmly adhere to the substrate before sintering, is present as titanium dioxide after sintering, and is used in an amount controlled so that a coating film can be formed, preferably not in excess, and allows the conductive component to firmly adhere to the substrate; the metal oxide formed after sintering the tantalum pentachloride can ensure that the conductive film is firmly adhered to the titanium substrate without falling off, and can prevent nascent oxygen from passing through the coating to a certain extent and prevent interstitial corrosion; thereby significantly extending the anode life.
The utility model provides an among the above scheme, the coating that the graphite oxide dispersion formed has formed graphite alkene layer after the sintering, and graphite alkene has given the positive pole good electric conductivity to reduce the chlorine evolution electric potential of positive pole, reduced the incidence of oxygen evolution side reaction, further improved the positive pole life-span.
In general, the reduction in anode life is multifactorial. The main reasons for this are: 1, the concentration of the electrolyte is low, and oxygen evolution side reaction is easier to occur when 3wt% dilute brine is electrolyzed than when saturated salt brine is electrolyzed; and 2, once the coating falls off and oxygen evolution side reaction occurs, nascent oxygen has small particles and high activity and can react with the titanium substrate through the coating, so that a titanium dioxide passivation layer is formed between the coating and the substrate for a long time, and once the titanium dioxide passivation layer is formed, the anode loses efficacy and macroscopically shows that the coating is easy to fall off. Therefore, to increase the anode life, it is necessary to keep the anode coating effective for a long period of time; on the one hand, the occurrence of oxygen evolution side reactions can be reduced; on the other hand, it can also be improved by preventing the nascent oxygen from permeating through the anodic coating. In the prior art, the method is implemented by improving the composition and the proportion of a conductive component and a non-conductive component in the coating, for example, the addition amount of ruthenium chloride is increased to improve the conductivity and the electrocatalytic activity, thereby reducing the chlorine evolution potential; on the other hand, the dosage of tantalum chloride is increased to block the permeation of nascent oxygen, improve the adhesion of the coating and delay the interstitial corrosion.
The utility model discloses still utilized the special property of graphite alkene, improved the electric conductivity of coating on the one hand, improved the electro-catalytic activity, reduced chlorine evolution potential, on the other hand has also improved the stability of coating. But because the dispersibility of the graphene is not good, the utility model adopts the graphene oxide dispersion liquid and adds the silane coupling agent; the graphene oxide is uniformly dispersed and firmly combined with the titanium substrate, so that the combination of nascent oxygen and the titanium substrate is hindered, and the passivation of the titanium substrate is avoided.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
