And the condenser, as an important economic equipment of the condensing steam turbine, plays an important role in thermal power plants; the cleanliness of the condenser is one of the important indicators of its economic performance. For units with qualified vacuum tightness, the dirt on the inner wall of the condenser heat exchange tubes is the main factor leading to a large end difference and low performance of the condenser.

[0074] As an important industrial prime mover, various types of steam turbines are widely used in productivity and mechanical transmission. And the condenser, as an important economic equipment of the condensing steam turbine, plays an important role in thermal power plants; the cleanliness of the condenser is one of the important indicators of its economic performance. For the units with qualified vacuum tightness, the dirt on the inner wall of the condenser heat exchange tubes is the main factor leading to large end difference and low performance of the condenser. Therefore, it is not only necessary to detect and clean the dirt on the inner wall of the condenser heat exchange tubes in real time, but also to prevent the dirt from adhering to the inner wall of the condenser heat exchange tubes.

[0075] As Figure 1 shown, this embodiment discloses an intelligent electromagnetic antibacterial and scale removal method for a power plant condenser, including:

[0076] Step S1, obtaining the data information and water flow parameters on the cooling water pipeline of the condenser;

[0077] Step S2, determining the number of turns of the coil of the electromagnetic antibacterial component based on the data information on the cooling water pipeline;

[0078] Step S3: Determine the electromagnetic wave frequency emitted by the electromagnetic antibacterial component based on the water flow parameters.

[0079] It can be understood that in the above embodiments, the electromagnetic antibacterial component is fixed on the cooling water pipeline of the condenser. The cooling water pipeline includes heat exchange tubes; the electromagnetic antibacterial component includes an electromagnetic wave coil wound around the cooling water pipeline. Based on the water flow parameters, the electromagnetic wave emitted by the electromagnetic antibacterial component is determined to cause the water flow in the cooling water pipeline to resonate, increase the internal energy of the water, and form a non-adhesive high-energy calcium carbonate and magnet layer in the cooling water system to prevent scaling and corrosion.

[0080] Such as Figure 2 shown, in some specific embodiments, the data information on the cooling water pipeline includes the diameter and wall thickness of the cooling water pipeline.

[0081] In step S2, determining the number of turns of the coil of the electromagnetic antibacterial component based on the data information on the cooling water pipeline includes:

[0082] Step S21: Determine the number of turns of the coil of the electromagnetic antibacterial component based on the diameter of the cooling water pipeline.

[0083] Step S22: Modify the number of turns of the coil of the electromagnetic antibacterial component based on the wall thickness of the cooling water pipeline.

[0084] It can be understood that in the above embodiments, the number of turns of the coil of the electromagnetic antibacterial component affects whether the electromagnetic wave can cause resonance of the water molecules in the cooling water pipeline. Therefore, it is necessary to accurately set the number of turns of the coil of the electromagnetic antibacterial component. By determining the number of turns of the coil of the electromagnetic antibacterial component based on the diameter of the cooling water pipeline, the accuracy of setting the number of turns of the coil is improved; modifying the number of turns of the coil of the electromagnetic antibacterial component based on the wall thickness of the cooling water pipeline further improves the accuracy of setting the number of turns of the coil.

[0085] Specifically, determining the number of turns of the coil of the electromagnetic antibacterial component based on the diameter of the cooling water pipeline includes: presetting a diameter matrix D, setting D(D1, D2, D3, D4), where D1 is the first preset diameter, D2 is the second preset diameter, D3 is the third preset diameter, D4 is the fourth preset diameter, and D1 < D2 < D3 < D4;

[0091] When D3 < D ≤ D4, set the fourth preset number of turns of the coil Z4 as the number of turns of the coil Z.

[0092] It can be understood that in the above embodiments, the preset diameter matrix D is set as D(40, 50, 65, 80), where 40 is the first preset diameter, 50 is the second preset diameter, 65 is the third preset diameter, 80 is the fourth preset diameter, and 40 < 50 < 65 < 80, with the unit being mm;

[0093] The preset number of turns of the coil matrix Z is set as Z(20, 30, 40, 50), where 20 is the first preset number of turns of the coil, 30 is the second number of turns of the coil, 40 is the third number of turns of the coil, and 50 is the fourth number of turns of the coil;

[0094] Obtain the actual diameter on the cooling water pipe, and set the number of turns of the coil of the electromagnetic antibacterial component based on the relationship between the actual diameter on the cooling water pipe and the preset diameter. Specifically:

[0095] When D ≤ 40, set the first preset number of turns of the coil 20 as the number of turns of the coil Z;

[0096] When 40 < D ≤ 50, set the second preset number of turns of the coil 30 as the number of turns of the coil Z;

[0097] When 50 < D ≤ 65, set the third preset number of turns of the coil 40 as the number of turns of the coil Z;

[0098] When 65 < D ≤ 80, set the fourth preset number of turns of the coil 50 as the number of turns of the coil Z.

[0099] When the actual diameter obtained on the cooling water pipe is 45 mm, select the number of turns of the coil of the electromagnetic antibacterial component as 30 based on the relationship between the actual diameter on the cooling water pipe and the preset diameter.

[0100] It should be noted that the matrices of the preset diameter matrix D and the preset number of turns of the coil matrix Z can be determined according to the actual situation.

[0101] Specifically, correcting the number of turns of the coil of the electromagnetic antibacterial component based on the wall thickness of the cooling water pipe includes:

[0102] A preset wall thickness matrix d0 is provided in advance. For the preset wall thickness matrix d0, d0(d1, d2, d3, d4) is set, where d1 is the first preset wall thickness, d2 is the second preset wall thickness, d3 is the third preset wall thickness, d4 is the fourth preset wall thickness, and d1 < d2 < d3 < d4;

[0103] A preset correction coefficient matrix ai is provided in advance. For the preset correction coefficient matrix ai, ai(a1, a2, a3, a4) is set, where a1 is the first preset correction coefficient, a2 is the second preset correction coefficient, a3 is the third preset correction coefficient, a4 is the fourth preset correction coefficient, and a1 < a2 < a3 < a4;

[0104] Based on the relationship between the actual wall thickness and the preset wall thickness on the cooling water pipe, the i-th preset correction coefficient ai is selected to correct the number of turns Z of the electromagnetic antibacterial component, where i = 1, 2, 3, 4:

[0105] When d < d1, the first preset correction coefficient a1 is selected to correct the number of turns of the coil, and the corrected number of turns of the coil is Z * a1;

[0106] When d1 ≤ d < d2, the second preset correction coefficient a2 is selected to correct the number of turns of the coil, and the corrected number of turns of the coil is Z * a2;

[0107] When d2 ≤ d < d3, the third preset correction coefficient a3 is selected to correct the number of turns of the coil, and the corrected number of turns of the coil is Z * a3;

[0108] When d3 ≤ d < d4, the fourth preset correction coefficient a4 is selected to correct the number of turns of the coil, and the corrected number of turns of the coil is Z * a4.

[0109] It can be understood that in the above embodiments, a preset wall thickness matrix d0 is provided in advance. For the preset wall thickness matrix d0, d0(2, 2.5, 3, 3.5) is set, where 2 is the first preset wall thickness, 2.5 is the second preset wall thickness, 3 is the third preset wall thickness, 3.5 is the fourth preset wall thickness, and 2 < 2.5 < 3 < 3.5;

[0110] A preset correction coefficient matrix ai is provided in advance. For the preset correction coefficient matrix ai, ai(0.8, 0.9, 1, 1.1) is set, where 0.8 is the first preset correction coefficient, 0.9 is the second preset correction coefficient, 1 is the third preset correction coefficient, 1.1 is the fourth preset correction coefficient, and 0.8 < 0.9 < 1 < 1.1;

[0111] Based on the relationship between the actual wall thickness and the preset wall thickness on the cooling water pipe, the i-th preset correction coefficient ai is selected to correct the number of turns Z of the electromagnetic antibacterial component, where i = 1, 2, 3, 4:

[0112] When d < 2, select the first preset correction coefficient 0.8 to correct the number of turns of the coil, and the corrected number of turns of the coil is Z * 0.8;

[0113] When 2 ≤ d < 2.5, select the second preset correction coefficient 0.9 to correct the number of turns of the coil, and the corrected number of turns of the coil is Z * 0.9;

[0114] When 2.5 ≤ d < 3, select the third preset correction coefficient 1 to correct the number of turns of the coil, and the corrected number of turns of the coil is Z * 1;

[0115] When 3 ≤ d < 3.5, select the fourth preset correction coefficient 1.1 to correct the number of turns of the coil, and the corrected number of turns of the coil is Z * 1.1.

[0116] When the actual diameter on the cooling water pipe is obtained as 45 mm, and the number of turns of the coil of the electromagnetic antibacterial component is selected as 30 based on the relationship between the actual diameter on the cooling water pipe and the preset diameter; when the actual wall thickness on the cooling water pipe is 3.2 mm, the corrected number of turns of the coil of the electromagnetic antibacterial component is 33.

[0117] It should be noted that the preset wall thickness matrix d0 and the preset correction coefficient matrix ai can be set according to the actual situation.

[0118] In some specific embodiments, the water flow parameters include the water flow temperature. Determining the electromagnetic wave frequency emitted by the electromagnetic antibacterial component based on the water flow parameters includes:

[0119] Preset temperature matrix T, set T(T1, T2, T3, T4), where T1 is the first preset temperature, T2 is the second preset temperature, T3 is the third preset temperature, T4 is the fourth preset temperature, and T1 < T2 < T3 < T4;

[0120] Preset electromagnetic wave frequency array P, set P(P1, P2, P3, P4), where P1 is the first preset electromagnetic wave frequency, P2 is the second electromagnetic wave frequency, P3 is the third electromagnetic wave frequency, P4 is the fourth electromagnetic wave frequency, and T1 > T2 > T3 > T4;

[0121] Obtain the actual temperature on the cooling water pipe, and set the electromagnetic wave frequency of the electromagnetic antibacterial component based on the relationship between the actual temperature on the cooling water pipe and the preset temperature, specifically:

[0122] When T ≤ T1, set the first preset electromagnetic wave frequency P1 as the electromagnetic wave frequency P;

[0123] When T1 < T ≤ T2, set the second preset electromagnetic wave frequency P2 as the electromagnetic wave frequency P;

[0124] When T2 < T ≤ T3, set the third preset electromagnetic wave frequency P3 as the electromagnetic wave frequency P;

[0125] When T3 < T ≤ T4, set the fourth preset electromagnetic wave frequency P4 as the electromagnetic wave frequency P.

[0126] It can be understood that in the above embodiments, the electromagnetic wave frequency is between 30 Hz and 300 Hz. At the same electromagnetic wave frequency, the resonance of water flow molecules at different temperatures is different, and the water flow temperature is a factor affecting the resonance descaling of water molecules.

[0127] It should be noted that similar to the fact that the matrices of the above preset diameter matrix D and preset coil turn matrix Z can be determined according to the actual situation, the preset temperature matrix T and preset electromagnetic wave frequency matrix P can also be determined according to the actual situation, which will not be elaborated here.

[0128] As Figure 3 shown, in some specific embodiments, the water flow parameters include the water flow inlet flow rate and the water flow outlet flow rate, and the flow rate difference is determined based on the inlet flow rate and the outlet flow rate;

[0129] In step S3, determining the electromagnetic wave frequency emitted by the electromagnetic bacteriostatic component based on the water flow parameters further includes:

[0130] Step S31, determining the degree of hard scale adhesion on the inner wall of the heat exchange tube based on the relationship between the flow rate difference and the preset flow rate difference threshold;

[0131] Step S32, determining the descaling electromagnetic wave frequency and the descaling electromagnetic wave time emitted by the electromagnetic bacteriostatic component based on the relationship between the degree of hard scale adhesion on the inner wall of the heat exchange tube and the preset adhesion degree.

[0132] It can be understood that in the above embodiments, the electromagnetic wave frequency is between 30 Hz and 300 Hz. At the same electromagnetic wave frequency, the resonance of water flow molecules at different temperatures is different, the degree of hard scale adhesion on the inner wall of the heat pipe is different, and the required descaling electromagnetic wave frequency is different. Determining the degree of hard scale adhesion on the inner wall of the heat exchange tube based on the relationship between the flow rate difference and the preset flow rate difference threshold can avoid disassembling the heat exchange tube of the condenser for descaling cleaning, and improve the accuracy of determining the degree of hard scale adhesion on the inner wall of the heat exchange tube. By accurately determining the descaling electromagnetic wave time, emitting the descaling electromagnetic wave, and performing precise descaling on the inner wall of the heat exchange tube. When it is confirmed that the descaling of the inner wall of the heat exchange tube is completed, the original electromagnetic wave frequency is restored.

[0133] It should be noted that the above preset flow rate difference threshold and descaling electromagnetic wave time can be determined according to the actual situation.

[0134] Specifically, determining the degree of hard scale adhesion on the inner wall of the heat exchange tube based on the relationship between the flow rate difference and the preset flow rate difference threshold includes:
