Background
China is a world major country for non-ferrous metal metallurgy and is also a major country for producing basic metals, and according to introduction of the subsidiary book of the national non-ferrous metal industry association, the long Jiaming star, which is held in Yuanyue 29 days in this year, the yield of ten non-ferrous metals in China firstly breaks through 6000 million tons in 2020, and reaches 6168.0 million tons. However, the power consumption of the basic metal smelting is huge, wherein the power consumption of the electrolysis production process accounts for the largest proportion, for example, according to related statistical data, the zinc electrolysis production needs to consume 3000 degrees/ton of electric energy, the power consumption accounts for 70-80% of the total power consumption of the zinc production, the electrolysis power consumption comprises direct current power consumption and alternating current power consumption, and the direct current power consumption accounts for 90% of the electrolysis power consumption. In the above energy consumption, the unnecessary energy loss caused by the short circuit of the cathode and the anode during electrolysis is up to 5-10%.
The structural principle of the existing electrolysis system is shown in figure 1. The reason why the short circuit between the cathode and the anode during the electrolysis is caused is that the short circuit between the cathode and the anode can be caused because the conductive rod of the polar plate is not placed well or the metal is in the precipitation process, the electrolytic metal precipitation speed at a certain protruding position is high, particles (i.e. nodules) can grow on the cathode plate, the nodules are too long and are in contact with the anode plate, thereby causing the short circuit of the cathode plate and the anode plate, the short circuit of the electrolytic polar plate can cause the current between the polar plates to be increased sharply and influence the electrolytic current of other electrolytic polar plates, the electrolytic efficiency is reduced, the energy consumption is increased, the cost is increased, and meanwhile, the purity of the smelted metal can also be influenced. Therefore, how to detect the short circuit and the open circuit of the cathode and anode plates and discharge the short circuit and the open circuit in time so as to reduce energy consumption and ensure normal production becomes a technical problem which is urgently needed to be overcome by metal smelting enterprises, and if monitoring and control intellectualization can be realized, the method can save hundreds of billions of degrees of electric energy for manufacturers adopting the electrolytic production process in China every year.
At present, for non-ferrous metal smelting is taken as an example, in the non-ferrous metal electrolysis process in China, the state detection of a polar plate adopts a manual itinerant and manual detection mode, an operator needs to see through hands, judge whether a short circuit or open circuit condition exists or not by combining working experience, and then eliminate the short circuit or open circuit condition one by one, so that the detection and obstacle removal speed is low, the accuracy is low, the labor intensity of the worker is high, in addition, the corrosivity and the toxicity of electrolyte cause human body damage to the worker, and great health hidden dangers exist.
The chinese patent application No. 201020198990.1 discloses a short circuit identifier, and the utility model relates to an electrolytic short circuit identifier used in electrolytic processes such as metal electrolytic smelting and electrolytic plating. The technical scheme is as follows: the resistor, the reed switch and the alarm bell (or/and the alarm lamp) are connected in series by a lead and then connected with two poles of a battery (set) to form a short circuit identification circuit system, then the whole circuit system is installed in an insulating box with a handle, and the alarm lamp can give an alarm by measuring strong current generated by short circuit. In the electrolysis workshops of large enterprises with the output of tens of thousands of tons or tens of thousands of tons, the electrolysis short circuit recognizer has a complex structure, a recognizer matched between every two polar plates is needed, the number is large, the installation is extremely difficult, and the popularization and the application are difficult in the actual production.
The Chinese patent document with the application number of 202010402480.X discloses an automatic inspection and treatment system for short circuit and open circuit of an electrolytic plate in nonferrous metal electrorefining, the technical scheme is applied to inner Mongolia smelting enterprises, and the design idea is that the inspection of an intelligent detection locomotive is used for replacing manpower, so that the efficiency is improved, and the health of workers is protected. However, the system is expensive in manufacturing cost, the temperature change during the patrol is taken as a detection means, the patrol speed is slow due to certain lag of temperature rise generated after the short-circuit fault occurs, the short-circuit fault cannot be found in time, and in addition, the technical scheme also detects the current between the polar plates.

Detailed Description
As shown in fig. 2, the method for early warning and detecting the short circuit of the electrolytic plate in the embodiment includes:
1) collecting the voltage between the cathode and the anode of the target electrolytic cell;
2) and if the voltage between the cathode and the anode meets a preset short-circuit early warning condition, outputting a target electrolytic tank short-circuit early warning signal, wherein the preset short-circuit early warning condition means that the voltage between the cathode and the anode is less than the preset short-circuit early warning voltage, and the preset short-circuit early warning voltage is less than the rated working voltage between the cathode and the anode of the target electrolytic tank.
And outputting a short-circuit early warning signal of the target electrolytic tank, and indicating that the nodulation degree between one or more pairs of cathode plates and anode plates of the target electrolytic tank reaches a short-circuit early warning state. The output target electrolytic bath short-circuit early warning signal can select a required form including images, videos, light, electricity and other signals according to needs so as to inform relevant workers of removing faults.
It should be noted that the preset short-circuit warning voltage is related to the electrolytic nodulation height between the cathode and the anode, and a required value can be selected according to needs. In addition, in the case that a plurality of electrolytic cells are connected in series, the short-circuit voltage is distributed to the rest of the normal electrolytic cells, but the rated working voltage between the cathode and the anode of the electrolytic cells is small (for example, the rated working voltage between the cathode and the anode of the electrolytic cell for electrolyzing zinc is 3V), and the number of the electrolytic cells is large, so that the working voltage of the rest of the electrolytic cells is not changed greatly, and therefore, a fixed preset short-circuit early warning voltage can be adopted as a judgment reference, for example, 2V.
As an alternative embodiment, the present embodiment also enables open circuit detection of the target electrolytic cell. The step 2) also comprises the following steps: and if the voltage between the cathode and the anode meets a preset open circuit judgment condition, judging that one or more groups of cathodes and anodes of the target electrolytic tank are open circuit, wherein the preset open circuit judgment condition means that the voltage between the cathodes and the anodes is greater than a preset open circuit reference voltage, and the preset open circuit reference voltage is greater than the rated working voltage between the cathodes and the anodes of the target electrolytic tank. In the event of a short circuit, failure of the cells in series can result, requiring emergency handling by workers. In this embodiment, the step of determining that one or more groups of cathodes and anodes of the target electrolytic cell are disconnected further comprises sending an alarm to notify manual processing.
During electrolysis, under the action of the applied DC voltage, the positive ions in the electrolyte move to the cathode to obtain electrons at the cathode, and the electrons are reduced, and the negative ions move to the anode to lose electrons at the anode and are oxidized. From the electrical point of view, this is only the process of current flowing through the cathode and anode plates with internal resistance in the electrolytic cell, that is, several tens of plates of one electrolytic cell can be regarded as a plurality of resistors connected in parallel. During the electrolytic operation, the situation that the cathode plate and the anode plate are short-circuited due to the fact that particles (i.e. nodules) can grow on the cathode plate due to the fact that the polar plate conducting rod is not placed well or the electrolytic metal precipitation speed is high at a certain protruding position in the metal precipitation process, the nodules are too long and contact with the anode plate can be considered to be caused because the internal resistance is connected through one conducting wire. According to the above discussion, in order to solve the problem of detecting the short circuit of the anode and cathode plates, it is necessary to find the specific position of the anode and cathode plates with short circuit in tens or hundreds of electrolytic cells, and each electrolytic cell has tens of anode and cathode plates, which brings great difficulty to the fault location. In order to solve the above technical problem, the method further includes, after outputting the short warning signal of the target electrolytic cell in step 2), diagnosing the position of the short warning cathode and anode plates in the target electrolytic cell: firstly, all controlled switches of a target electrolytic tank are turned off, then, all controlled switches of the target electrolytic tank are sequentially turned on, and the rest controlled switches are kept turned off, the controlled switches correspond to at least one pair of cathode plates and anode plates and are connected in series on loops of the corresponding cathode plates and anode plates, if a certain controlled switch is found to be turned on so that the voltage between the corresponding cathode plates and the corresponding anode plates still meets the preset short-circuit early warning condition, the position of the cathode plates and the anode plates corresponding to the controlled switch is judged to be a short-circuit early warning position. As an optional implementation manner, in this embodiment, the controlled switch is an electric control switch, a way that a cathode or an anode can be directly placed on the conductive copper bar is changed, the electric control switch is added between the cathode or the anode and the conductive copper bar, a voltage detection assembly is additionally arranged between any cathode and any anode in each electrolytic cell, when a short circuit occurs between the cathode and the anode in a certain electrolytic cell, the voltage between the cathode and the anode detected by the voltage detection assembly of the electrolytic cell is less than a preset short-circuit early warning voltage, and at this time, it can be determined that one or more pairs of electrode plates in the electrolytic cell are short-circuited. The electric control switches of the electrolytic cell are all disconnected, and are closed one by one, and the other controlled switches are kept disconnected for testing, when a certain polar plate is closed and the other controlled switches are kept disconnected, the voltage monitored by the voltage detection assembly meets a preset short-circuit early warning condition, the positions of the cathode plate and the anode plate corresponding to the controlled switches can be judged to be early warning positions, and if the voltage meets the preset short-circuit early warning condition for many times, the electrolytic cell has a plurality of early warning positions. Considering that each electrolytic cell has dozens of cathode plates and anode plates, and the problem of low efficiency and long time consumption exists when each controlled switch of the target electrolytic cell is sequentially closed, in order to improve the efficiency of diagnosing the position of the cathode plate and the anode plate in the target electrolytic cell for short-circuit early warning, in this embodiment, sequentially closing each controlled switch of the target electrolytic cell and keeping the rest of the controlled switches open means:
s1) forming an initial candidate controlled switch set by all the controlled switches;
s2) dividing the controlled switches in the candidate controlled switch set into two groups, respectively closing the controlled switches of each group and keeping the ports of the other group of controlled switches aiming at each group of controlled switches, if the voltage between the corresponding cathode and anode does not meet the preset short-circuit early warning condition when the group of controlled switches are closed, removing the group of controlled switches from the candidate controlled switch set, and jumping to execute the step S2 after the two groups of controlled switches are processed); if the voltage between the corresponding cathode and anode does not meet the preset short-circuit early warning condition when a certain group of controlled switches are closed is not found finally, skipping to execute the next step;
s3) traversing each controlled switch in the candidate controlled switch set, controlling the current controlled switch to be closed and other controlled switches to be opened aiming at each traversed current controlled switch, and if the voltage between the cathode and the anode corresponding to the current controlled switch meets the preset short-circuit early warning condition, judging that the position of the cathode plate and the anode plate corresponding to the current controlled switch is the early warning position.
As a preferred embodiment, the step S2) of dividing the controlled switches in the candidate controlled switch set into two groups means, specifically, equally dividing into two groups, and other dividing manners may be selected as needed. Therefore, when the controlled switches in the candidate controlled switch set are divided into two groups in step S2), the two groups of controlled switches are equal in number (in the case where the candidate controlled switch set is even) or differ by 1 (in the case where the candidate controlled switch set is odd).
In this embodiment, after the position of the short-circuit early warning cathode and anode plates in the target electrolytic tank is diagnosed, the method further includes the step of turning off all the controlled switches corresponding to the cathode and anode plates with the short circuit and turning on all the controlled switches corresponding to the cathode and anode plates without the short circuit, so that the target electrolytic tank continues to be usable, and thus a phenomenon that one electrode plate is short-circuited to cause the whole electrolytic tank to work abnormally is avoided.
