[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] 10mg / Nm3, 10 milligrams per standard cubic meter,

[0048] The present application embodiment provides an energy-saving method for an electrostatic precipitator system, which is applied to the electrostatic precipitator system. Figure 1 , the method may include the following steps.

[0049] S101, obtaining emission values ​​and energy consumption values ​​of the electrostatic precipitator system.

[0050] Among them, the emission value is used to indicate the outlet dust concentration of the electrostatic precipitator system, and the energy consumption value is used to indicate the power consumption of the electrostatic precipitator system.

[0051] Optionally, obtain emission and energy consumption values ​​of the electrostatic precipitator system, including:

[0052] Obtain the outlet dust concentration of multiple electrostatic precipitator systems monitored during a preset energy-saving period;

[0053] Calculate the average value of dust concentrations at multiple outlets and determine the calculation result as the emission value;

[0054] Obtain the total power of multiple electrostatic precipitator systems monitored during the energy-saving period;

[0055] An average value of the multiple powers is calculated, and the calculation result is determined as the energy consumption value.

[0056] The length of the preset energy-saving period can be set as needed without limitation. For example, the energy-saving period can be set to the most recent month.

[0057] Therefore, the implementation method of step S101 may include calculating the average value of the outlet dust concentration monitored in the last month to obtain the emission value. The outlet dust concentration of the electrostatic precipitator system can be monitored once a day or at other frequencies without limitation.

[0058] At the same time, the total power of the electrostatic precipitator system monitored in the most recent month is averaged and the result is used as the energy consumption value. The total power of the electrostatic precipitator system can be monitored once a day or at other frequencies without limitation.

[0059] An electrostatic precipitator system usually includes multiple electrostatic precipitators working simultaneously or not. The total power of the electrostatic precipitator system can be equal to the sum of the power of all the electrostatic precipitators in the electrostatic precipitator system. The power of each electrostatic precipitator can be equal to the product of the secondary voltage and secondary current of the electrostatic precipitator.

[0060] S102, calculating the energy saving space index of the electrostatic precipitator system according to the deviation of the emission value relative to the preset standard concentration and the deviation of the energy consumption value relative to the rated power of the electrostatic precipitator system.

[0061] The above-mentioned standard concentration may be the standard concentration specified in the technical standards related to the flue gas treatment field, and its specific value may be set according to the relevant standards and the needs of the factory using the electrostatic precipitator system.

[0062] For example, the standard concentration Em can be set to 8 mg / Nm3 (milligrams per standard cubic meter) according to the relevant standards of a certain region, which can be obtained by reducing 2 mg / Nm3 from the dust concentration of normal clean flue gas defined in the relevant standards of 10 mg / Nm3. Alternatively, it can be set to 4 mg / Nm3, which can be obtained by reducing 1 mg / Nm3 from the dust concentration of ultra-clean exhaust gas defined in the relevant standards of 5 mg / Nm3.

[0063] Among them, the energy-saving space index is used to indicate the extent to which the power consumption of the electrostatic precipitator system can be reduced (also known as the energy-saving space) under the condition that the emission standards are met.

[0064] The emission compliance condition means that the outlet dust concentration of the electrostatic precipitator system is not higher than the above standard concentration.

[0065] In other words, the energy-saving space index reflects the size of the energy-saving space of the electrostatic precipitator system under the premise of ensuring that the outlet dust concentration of the electrostatic precipitator system is not higher than the standard concentration. The larger the energy-saving space index, the larger the energy-saving space of the electrostatic precipitator system under this premise, that is, the power consumption can be greatly reduced by taking energy-saving measures. Correspondingly, the smaller the energy-saving space index, the smaller the energy-saving space of the electrostatic precipitator system under this premise, that is, the power consumption cannot be reduced by taking energy-saving measures, or the reduction can be limited.

[0066] Optionally, since the energy-saving space index must be based on meeting the emission standard conditions, in step S102, it can be determined whether the emission value is greater than or equal to the standard concentration. If the emission value is greater than or equal to the standard concentration, the outlet dust concentration is prioritized to meet the standard conditions. It can be considered that there is no energy-saving space. At this time, the energy-saving space index can be directly set to 0 without calculation. The energy-saving space index is only calculated when the emission value is less than the standard concentration.

[0067] There may be multiple specific calculation methods for the energy-saving space index, which are not limited in this embodiment. Under the premise that the emission value is less than the standard concentration and the energy consumption value is less than the rated power, the greater the deviation between the emission value and the standard concentration, the greater the energy-saving space index, and the greater the deviation between the energy consumption value and the rated power, the smaller the energy-saving space index.

[0068] The energy-saving space index can be a real number in the range of 0 to 1. When the energy-saving space index is equal to 0, it means that the electrostatic precipitator system has no energy-saving space. When the energy-saving space index is equal to 1, it means that the energy-saving space of the electrostatic precipitator system has reached its upper limit.

[0069] S103, determining and outputting recommended energy-saving measures corresponding to the energy-saving space index.

[0070] The specific implementation of step S103 may be:

[0071] A number of index intervals are pre-set within the range of 0 to 1, for example, three index intervals are set, namely, the first index interval, the second index interval and the third index interval from low to high, and energy-saving measures corresponding to each index interval are set.

[0072] For example, the energy-saving measures corresponding to the lowest first index interval may include: the current energy-saving space is small, and it is recommended to fine-tune one or more of the working voltage, working current and working time of the electrostatic precipitator system to further reduce energy consumption.

[0073] The energy-saving measures corresponding to the higher second index interval may include: the current energy-saving space is large, and it is recommended to enable the energy-saving algorithm of the electrostatic precipitator system to reduce system energy consumption.

[0074] The energy-saving measures corresponding to the highest third index interval may include: there is currently a lot of room for energy saving, and it is recommended to carry out energy-saving transformation of the electrostatic precipitator system to significantly reduce energy consumption. The energy-saving transformation can be carried out by replacing new electrostatic precipitator equipment or reducing the number of electrostatic precipitator equipment operating in the electrostatic precipitator system.

[0075] Based on the above settings, when executing S103, it can be determined which index interval the currently calculated energy-saving space index belongs to, and then the energy-saving measure corresponding to the index interval is determined as the recommended energy-saving measure of step S103 and outputted.

[0076] The recommended energy-saving measures may be output in the form of displaying corresponding text on a screen or broadcasting corresponding voice through a speaker.

[0077] It should be noted that the method provided in the present application can automatically run regularly according to a certain cycle during the operation of the electrostatic precipitator system, thereby outputting a dynamic energy-saving space index and corresponding recommended energy-saving measures at regular intervals, providing a reference for the energy-saving transformation of the system in real time during the operation of the electrostatic precipitator system.

[0078] Optionally, after the method provided in this embodiment is executed multiple times, the energy-saving space index outputted from the multiple executions can be outputted on a display screen in the form of a data table or a statistical graph (such as a curve) for the user to view.

[0079] The present application provides an energy-saving method for an electrostatic precipitator system, which is applied to the electrostatic precipitator system, and the method includes: obtaining the emission value and energy consumption value of the electrostatic precipitator system; wherein the emission value is used to indicate the outlet dust concentration of the electrostatic precipitator system, and the energy consumption value is used to indicate the power consumption of the electrostatic precipitator system; according to the deviation of the emission value relative to the preset standard concentration, and the deviation of the energy consumption value relative to the rated power of the electrostatic precipitator system, the energy-saving space index of the electrostatic precipitator system is calculated; wherein the energy-saving space index is used to indicate the range of reduction of the power consumption of the electrostatic precipitator system under the condition that the emission meets the standard; determine and output the recommended energy-saving measures corresponding to the energy-saving space index. This scheme comprehensively considers the emission value and energy consumption value of the electrostatic precipitator system to give corresponding recommended energy-saving measures, avoiding the hidden danger of substandard emissions when energy-saving transformation is carried out considering only energy consumption.

[0080] In the energy-saving method for the electrostatic precipitator system provided in the present application, there are many methods for calculating the energy-saving space index, and this embodiment does not limit the specific algorithm.

[0081] As an example, the energy-saving space index can be calculated by using the calculation method provided in the following embodiment. Figure 2 , which is a flow chart of the method for calculating the energy-saving space index provided in this embodiment, and the method may include the following steps.

[0082] S201, based on the emission value, calculate the emission factor using a preset first formula. The emission factor is 1 minus the ratio of the emission value to the standard concentration.

[0083] Specifically, the first formula is: Ke=1-Ev / Em; Ke is the emission factor, Ev is the emission value, and Em is the standard concentration.

[0084] It can be seen that the deviation between the emission value and the standard concentration directly determines the size of the emission value. When the emission value is less than or equal to the standard concentration, the greater the deviation, the greater the emission value, and the smaller the deviation, the smaller the emission value.

[0085] Optionally, for convenience of calculation, the lower limit Ke of the emission factor can be set to 0, that is, when Ev is greater than or equal to Em, the calculation result of the above first formula is less than or equal to 0, and Ke can be uniformly set to 0 at this time.

[0086] S202: Based on the energy consumption value, calculate the energy consumption factor using a preset second formula. The energy consumption factor is the ratio of the deviation between the energy consumption value and the rated power to the rated power.

[0087] Among them, the second formula is: Kp=(P1-0.25P2) / (0.8P2-0.25P2), Kp is the energy consumption factor, P1 is the energy consumption value, and P2 is the rated power.

[0088] It can be seen that the deviation between the energy consumption value and the rated power directly determines the size of the energy consumption value. When the energy consumption value is in the range of 25% to 80% of the rated power, the greater the deviation, the smaller the energy consumption value, and the smaller the deviation, the greater the energy consumption value.

[0089] In the above formula, for the convenience of calculation, the lower limit of the energy consumption value can be set equal to 25% of the rated power. If the energy consumption value is less than or equal to 25% of the rated power, it is directly set to 25% of the rated power. The upper limit of the energy consumption value is set equal to 80% of the rated power. If the energy consumption value is greater than or equal to 80% of the rated power, it is directly set to 80% of the rated power.

[0090] Further optionally, when the energy consumption value is less than or equal to 25% of the rated power, the energy-saving space index may not be calculated and may be directly set to 0, indicating that the current electrostatic precipitator system has no energy-saving space.

[0091] That is to say, in this embodiment, the energy consumption value in the range of 25% of the rated power to 80% of the rated power can be used as the energy consumption factor. When the energy consumption value is less than or equal to 25% of the rated power, it can be considered that the power consumption of the current electrostatic precipitator system has been reduced to the lowest, and there is no room for energy saving. Correspondingly, the energy consumption factor at this time is 0. When the energy consumption value is greater than or equal to 80% of the rated power, it can be considered that the energy saving space of the current electrostatic precipitator system has reached the maximum.

[0092] In this embodiment, the range of 25% of the rated power to 80% of the rated power is an exemplary range set according to the performance of the specific electrostatic precipitator equipment and engineering experience during use. In other optional embodiments, the range can also be adjusted according to actual conditions, such as adjusted to a range of 30% to 90% of the rated power, without limitation.

[0093] S203, based on the emission factors and the energy consumption factors, a preset third formula is used for weighted calculation to obtain an energy-saving space index of the electrostatic precipitator system.

[0094] Among them, the third formula is: Ks=Kp*S1+Ke*S2, Ks is the energy-saving space index, S1 is the energy consumption weight, S2 is the emission weight, and the sum of S1 and S2 is 1.

[0095] In some optional embodiments, in order to make the calculated energy-saving space index more realistically reflect the actual energy-saving space of the electrostatic precipitator system, the following steps may be added before step S203, that is, before the energy-saving space index of the electrostatic precipitator system is obtained by weighted calculation using a preset third formula based on emission factors and energy consumption factors:

[0096] Adjust emission weights and energy consumption weights based on emission factors and energy consumption factors.

[0097] The specific adjustment methods can be as follows:

[0098] First, the initial emission weight and the initial energy consumption weight whose sum is 1 are preset. For example, the initial values ​​of S1 and S2 are both set to 0.5, indicating that the energy consumption factor and the emission factor have the same influence on the energy-saving space.

[0099] Then, after obtaining the energy consumption value and the emission value in S201 and S202, if the deviation between the energy consumption value and the emission value is too large, S1 and S2 are adjusted. For example, when the deviation between the two is greater than or equal to 0.3, S1 and S2 are adjusted, and then step S203 is performed with the adjusted energy consumption weight and emission weight.

[0100] In contrast, if the deviation between the energy consumption value and the emission value is not too large, for example, less than 0.5, S1 and S2 are not adjusted, and step S203 is directly performed with the initial energy consumption weight and emission weight.

[0101] If the deviation between the energy consumption value and the emission value is too large, the weight corresponding to the larger one of the two will be adjusted down by a specified amount, and the weight corresponding to the smaller one of the two will be adjusted up by a specified amount. The specified amount can be the difference between the energy consumption value and the emission value divided by 2. For example, the deviation between the energy consumption value and the emission value reaches 0.6, which is obviously too large, so 0.6 is divided by 2 as the specified amount of 0.3. Then, if the energy consumption value is greater than the emission value, the energy consumption weight will be adjusted down by 0.3 and the emission weight will be adjusted up by 0.3. If the emission value is greater than the energy consumption value, the emission weight will be adjusted down by 0.3 and the energy consumption weight will be adjusted up by 0.3.

[0102] The advantage of doing so is that it avoids the situation where the actual energy-saving space of the electrostatic precipitator system is very small due to the unreasonable weight distribution, and a large energy-saving space index is still calculated. When the emission factor is too small or the energy consumption factor is too small, the actual energy-saving space of the electrostatic precipitator system is very small. The above adjustment method can ensure that the energy-saving space index calculated in the end is as small as possible, so that the energy-saving space index reflects the actual energy-saving space as realistically as possible.

[0103] According to the energy-saving method of the electrostatic precipitator system provided in the embodiment of the present application, the embodiment of the present application also provides an energy-saving device of the electrostatic precipitator system, which is applied to the electrostatic precipitator system, see Figure 3 , is a schematic diagram of the structure of the device, and the device may include the following units.

[0104] The acquisition unit 301 is used to acquire the emission value and energy consumption value of the electrostatic precipitator system.

[0105] Among them, the emission value is used to indicate the dust concentration of the flue gas after treatment by the electrostatic precipitator system, and the energy consumption value is used to indicate the power consumption of the electrostatic precipitator system.

[0106] The calculation unit 302 is used to calculate the energy-saving space index of the electrostatic precipitator system according to the deviation of the emission value relative to the preset emission standard and the deviation of the energy consumption value relative to the electrostatic precipitator system.

[0107] Among them, the energy-saving space index is used to indicate the extent to which the power consumption of the electrostatic precipitator system can be reduced under the condition that the emission standards are met.

[0108] The determination unit 303 is used to determine and output a recommended energy-saving measure corresponding to the energy-saving space index.

[0109] Optionally, when the acquisition unit 301 acquires the emission value and energy consumption value of the electrostatic precipitator system, it is specifically used to:

[0110] Obtain the outlet dust concentration of multiple electrostatic precipitator systems monitored during a preset energy-saving period;

[0111] Calculate the average value of dust concentrations at multiple outlets and determine the calculation result as the emission value;

[0112] Obtain the total power of multiple electrostatic precipitator systems monitored during the energy-saving period;

[0113] An average value of the multiple powers is calculated, and the calculation result is determined as the energy consumption value.

[0114] Optionally, the calculation unit 302 calculates the energy-saving space index of the electrostatic precipitator system according to the deviation of the emission value relative to the preset emission standard and the deviation of the energy consumption value relative to the electrostatic precipitator system, specifically for:
