Description
Technical field:
The utility model relates to a kind of particularly electric coagulation machine of industrial sewage that is used to dispose of sewage.
Background technology:
In the last thirty years, the example of much handling industrial sewage in electrolytic mode was once arranged both at home and abroad.The tempting part that adopts this method to dispose of sewage is
The speed of disposing of sewage is fast, efficient is high, take up an area of province, the civil engineering amount is little;
Good decolorizing effect;
Dispose of sewage and be not subjected to the influence of temperature Change.
In addition, electrolysis process is disposed of sewage, and also has the other advantage, for example, the automation degree of equipment height, simple to operate, be convenient to automatization control etc.
But the technological deficiency of having found water treatment electrolyzer itself has subsequently been ruined its favorable industrial market outlook.These subversive technological deficiencies find that after anatomizing main has only one, the rapid polarization of pole plate that Here it is.
The fatal problem that the rapid polarization of water treatment electrolyzer pole plate brings is
1, the metal polar plate surface is covered by dirt, and resistance increases.Electrolytic process can't smooth and easyly be analysed the positive plate metal ion into water body in a steady stream, and relies on to such an extent that the oxidation-reduction reaction finished of betatopic is weakened greatly.And one of its main mode of removing water pollutant of the water treatment of electrolytic process is exactly the oxidation-reduction reaction.Along with the weakening greatly of oxidation-reduction reaction, it also is self-evident that the efficient of disposing of sewage of water treatment electrolyzer descends greatly.
2, in order to improve the efficient of water treatment electrolyzer, have to increase current density.But increase current density and brought two direct results again:
Energy consumption increases, processing cost rises;
The speed of pole plate fouling is accelerated more.
So the water treatment electrolyzer just gets into a difficult position more and can not extricate oneself.
In addition, traditional water treatment electrolyzer all is a horizontal type electrobath, and the electrolyzer of this slot type structure has brought the other critical defect inevitably:
1) hydrogen that produces in electrolytic process of each electrolysis cells of horizontal type electrobath and oxygen all are not fully utilized but loss behind each electrolysis cells emersion water body.Because the nascent oxygen that produces in the electrolysis is the strongest oxygenant, it has the effect of intensive oxidation removal to pollutants in sewage, and it is the same with the oxidation-reduction reaction, is the important reaction that the water treatment electrolyzer is removed pollutent.In addition, nascent oxygen still is sewage decoloring, deodorizing and germ-resistant powerful measure.Therefore, be that same current density is added on the one hand, resistance strengthens because pole plate covers dirt, and electrolysis is insufficient and oxygen is separated out few; Overflow again on the other hand, can expect that like this scrubbing effect that nascent oxygen will play is just quite limited.
2) horizontal type electrobath and its all pole plates must clean and scale removal by shutting down.
3) the structure heaviness of equipment.
4) the sewage kind of Shi Yinging is limited.
5) utilization of hydrogen is insufficient again.Because hydrogen is the lightest gas, easier and emersion water body and the loss in electrolysis cells quickly of the hydrogen that electrolysis produces.Do not looked down upon the microbubble of this hydrogen, it is that the flco of the pollutent that will separate is realized and the best medium of water sepn.
At this state of the art of water treatment electrolyzer, proposed some both at home and abroad in succession and attempted to overcome or delay pole plate fouling polar technical measures.For example, regularly change pole plate polarity, in case the rapid fouling polarization of pole plate; Increase dc voltage and adopt high-frequency pulse current etc.But facts have proved that all these measures all fail fundamentally to overcome pole plate polar problem.
Chinese patent ZL94227395.8 discloses a kind of water treatment electrolyzer of operate continuously.Comprise the electrolyzer that contains water-in and water outlet, have the several piece parallel interval to arrange the alternate battery lead plate of positive and negative electrode in the electrolyzer, between per two adjacent battery lead plates, strike off element, strike off element and adopted both sides to have the scraper of elasticity blade.In secular industrial practice, comprise to the processing of hundreds of industrial sewage and in the actual industrial engineering of water treatment, find that still there are the following problems:
The open both sides of scraper section (L) are long.When the spacing between two sword face outer most edge is compressed into polar plate spacing, original designly only contact with polar board surface up and down for the doctor edge face, having become scraper also contacts with last bottom crown at two middle parts up and down in flakes, so just force the cleaner motor that the power that overcomes unnecessary frictional force will additionally be provided, increased than original design and Duoed 1.5 times to 2 times energy consumption.Figure 13 has represented the signal of this unreasonable design.Pole plate has also been suffered the unnecessary damage of scraping for this reason.
After the variation of the geometrical dimension of scraper section, especially sectional thickness can not be guaranteed the compression of scraper two sword faces, being out of shape by dotted line position shown in Figure 13 (ideal section) around crank axle of scraper section put in place.
The running of scraper is along with the loss of positive plate, the expansion of polar plate spacing, and the elastic dilatation deficiency of scraper (two sword faces), thereby the scale removal efficient of pole plate reduced.Generally, along with prolong duration of service, the attenuation of positive plate impels polar plate spacing to increase, and after polar plate spacing increased to a certain degree, the elastic dilatation deficiency of scraper was so that the doctor edge face can scrape bottom crown.So the advantage of efficiently disposing of sewage just weakens even disappears thereupon.As shown in figure 14.
Chinese patent ZL99231233.7 discloses a kind of polar plate spacing constant water treatment electrolyzer.Comprise a plurality of pole plate seats that positive plate is housed respectively that are arranged in parallel that are positioned on the pedestal, rotating shaft is contained in the rotating shaft and can wipes the cleaner that contains the sword face of the fouling on the yin, yang pole plate off with the rotating shaft rotation.In industrial practice, still there are the following problems in invention.
1. have only the electrolysis cells of half that the spontaneous depolarization device is arranged, half electrolysis cells can't be arranged the spontaneous depolarization device.
2. 1. by above-mentioned, this patent in fact only is equivalent to half platform high-efficiency sewage treatment unit except that the hydrogen with vertical electric coagulation machine, oxygen can make full use of.
3. realize that the coordination of cathode-anode plate spacing constant technology is complicated, poor reliability, cost is higher.

Above-mentioned rotating shaft is shaped as positive polygon prism, as is four-prism, and adjacent cleaner becomes 180 ° to be contained in the rotating shaft, and during cleaner work, adjacent two cleaners still become 180 ° of angles of cut, make circumferential motion synchronously, spin balancing.
It mainly is electrochemical process, chemical process and electrification-physical process that the process that electric coagulation machine is disposed of sewage is summed up.After sewage entered electric coagulation machine and adds direct current, above-mentionedization reason process almost was to take place simultaneously.These process reciprocal causations are complemented each other.During the utility model work, positive plate, negative plate are connected with the positive and negative electrode of direct supply respectively.
1) after sewage enters electric coagulation machine and passes to direct current, to get the oxidation-reduction reaction generation immediately that betatopic is a sign.The cleaner that is contained in the rotating shaft rotates with rotating shaft, and along with cleaner constantly cleans pole plate, the cathode-anode plate surface is cleaned bright and new all the time.The metal ion of positive plate is constantly analysed into water body like this, by the gain and loss of electronics, finishes the water pollutant oxidation-reduction is reacted.Along with the rotation of cleaner, positive plate is analysed into the ion of water body and is balancedly brought into water body everywhere, gets so that oxidation-reduction reacts balanced high-efficiency continuous carrying out along with the positive plate ion source is constantly analysed into water body, the hydroxide radical (OH) that electrolyzing sewage produces
-Form metal hydroxides with metal ion and (for example form Al
2(OH)
3).As everyone knows, metal hydroxides is exactly a water purification agent.The pollutent of the oxyhydroxide that electrolysis forms and the removal of redox reaction and other pollutent in the water body (as suspended substance etc.) generation aggregation forms the flco of a large amount of pollutents that is separated.This is the sequential reaction of oxidation-reduction reaction, and this is the essential step that pollutent in the sewage is separated from water body.
2) after sewage entered electric coagulation machine and passes to direct current, its cathode-anode plate produced the oxygen of hydrogen microbubble and status nascendi respectively endlessly.Along with the running of cleaner scraper, the oxygen of above-mentioned status nascendi constantly enters water body from the positive plate surface.As everyone knows, the oxygen of status nascendi is the strongest oxygenant, and it is not only removed pollutant oxidation in the water body, and it also plays crucial effects to decolouring, deodorizing, sterilization and the sterilization of sewage.The pollutent of oxidation removal is also as 1) in form flco.
Along with the running of cleaner scraper, the microbubble of the hydrogen on negative plate surface constantly enters water body and is uniformly distributed in water body by the stirring of cleaner, and then diminishes attached to making it proportion on the removed pollutent flco rapidly.Along with processed water flows out electric coagulation machine, the pollutent flco that adheres to a large amount of hydrogen microbubbles is floating rapidly to water surface formation scum silica frost from floating trough (aiming at electric coagulation machine water outlet setting), and strikes off with mechanical system.From the floating trough lower layer of water then is to infuse transparent discharge water clearly.This is removed pollutent and water body separating process.
Being promoted greatly of the utility model electric coagulation machine technical feature shows following all many-sides.
1) cleaner is removed the dirt of every pole plate upper and lower surface in real time, has not made the fouling chance.Like this, pole plate keeps the surface bright and new, level and smooth from start to finish, and unnecessary resistance is produced.Analyse metal ion continuously into processed sewage water body on pure and fresh positive plate surface, and the whole oxidation-reduction reaction that depends on electron exchange continues balanced efficient, then electrolyzing sewage handle must continue, efficiently, less energy-consumption.
2), sewage is produced nascent oxygen by continuous electrolysis on positive plate.Nascent oxygen is the strong oxidation removal of water pollutant, in addition 1) hydroxide radical (OH) that metal ion that anode is separated out described in and electrolyzing sewage produce
-Produce metal hydroxides (water purification agent), the pollutent of removing with water pollutant and strong oxidizing reaction produces aggregation, forms flco and then and water sepn.
1) with 2) process be that electric coagulation machine is efficiently disposed of sewage and the pollutent of removing realized separating with water body lay a good foundation.
3) slowly rotating of cleaner constantly stirred the sewage of each electrolysis cells, impels in the electrolytic process water body ionic concn even.Uniform ion concentration has not only solved the polarization problem of ionic concn, has also facilitated the oxidation-reduction reaction and aggregation high-level efficiency under the less energy-consumption simultaneously.This is the remarkable advantage that cleaner rotatablely moves and brings.
4) cleaner applying pole plate scrape commentaries on classics continuously, with the nascent oxygen that the positive plate surface constantly produces, softly balancedly bring processed sewage water body again into, impel the oxidizing reaction equilibrium of removing pollutent, the efficient generation.The microbubble of (being produced by negative plate) hydrogen that enters water body with the same manner is evenly and promptly attached to 2) described in flco on make flco proportion reduce rapidly.When processed water outflow electric coagulation machine entered the separator tank of special setting, the pollutent flco (being dirty slag) that adheres to bubble hydrogen floated rapidly in groove, and the realization pollutent separates with water.The dirty slag of come-up is struck off, the discharge water after lower floor is handled by electric coagulation machine in the groove.
This hydrogen and oxygen are scraped the result who enters processed water body from pole plate, eliminated electrolytic process fully, reduced the resistance at pole plate and water body interface, thereby reduced energy consumption at the gas curtain that polar board surface produces.
5) along with processed water by flowing on lower floor's electrolysis cells than the upper strata electrolysis cells, as shown in Figure 1, the oxygen that does not run out of is also with current direction upper strata electrolysis cells, realizes making full use of of oxygen.This is one of benefit of bringing of the vertical structure of electric coagulation machine.
Compare with existing electrolyzer, the utlity model has following advantage:
When 1) disposing of sewage, cathode-anode plate is bright and new, smooth and do not have fouling.Oxidation-reduction reaction, aggregation is stable and efficient.Therefore resistance is little, saving energy and efficient height.The speed of disposing of sewage improves greatly, and traditional water is handled electrolyzer sewage and must be stopped in machine 20～50 minutes, and the utility model electric coagulation machine residence time of disposing of sewage in machine has only 2 minutes, even shorter.
2) process is successive, need not to shut down and clean and scale removal because of mud in the machine gathers with pole plate fouling.(in the machine no mud gather, also non-scaling of pole plate)
3) microbubble of the oxygen of the status nascendi that produces of the electric coagulation machine process of disposing of sewage and a large amount of hydrogen is fully used and is not had loss.This has just increased the ability of strong oxidation decontamination, has also improved the isolating speed of removed pollutent and water body significantly.
4) because the rotation of cleaner, the scraper pole plate all surface that constantly nuzzles up has been eliminated in the electrolytic process attached to the hydrogen on the pole plate, oxygen curtain, has more improved the clearance of pollutent and has improved pollutent and water body velocity of separation, has also saved energy consumption.
5) because pole plate is constantly cleaned by scraper and processed water constantly is stirred in electrolysis cells, positive plate precipitating metal ion is smooth and easy and be evenly distributed in water body, solved that ionic concn is inhomogeneous, near the ionic concn of (ion is intensive polar board surface) polarization, reduced the water body resistance that increases owing to ionic concn is inhomogeneous, it has not only saved energy consumption, and has improved the efficient of disposing of sewage.
6) each electrolysis cells is provided with cleaner, and working stability, reliable is operated also more convenient laborsaving.
7) because the speed of disposing of sewage increases substantially, and therefore, the electric coagulation machine of same processing power is handled electrolyzer with traditional water and compared, and machine deadweight and volume reduce greatly, floor space is also saved greatly.The machine of same processing power, the electric coagulation machine structural weight only is 1/3rd to 1/5th of a traditional water treatment unit, and floor space (main frame is compared) only is 1/4th to 1/5th.
8) discharge water after the processing, the pollutent that it is got rid of and the velocity of separation of water body are exceedingly fast, and only need for tens seconds.Thus, totally handle electrolyzer and improved an order of magnitude than traditional water.
9) pollutants removal rate height.Containing heavy metal containing sewage and to contain (emulsification) oily water is example, electric coagulation machine to the clearance of heavy metal and oil up to 99%～99.99%.
10) the electric coagulation machine treating processes does not have dry sound generation.
11) scum silica frost after electric coagulation machine is disposed of sewage, structure is tight, and water ratio is low.This has significantly reduced workload and investment for dirty slag subsequent disposal.
12) form processing power normalization product from small to large easily, also more be suitable for mass industrialized production.
13) applied widely, experiment showed, that industrial sewages such as the utility model electric coagulation machine not only can be used for printing and dyeing, plating also can be used for the processing of other kind sewage:
Sanitary sewage, water reuse in comprising;
Food and drink oil-containing and grease sewage, contain emulsifying greasy dirt water at oil-containing;
Printing and dyeing (all kinds of fabric) sewage;
