[0021] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application, and are not used to limit the present application.

[0022] In order to better understand the technical solutions of the present application, the following will be described in detail in combination with the drawings in the specification and the specific embodiments.

[0023] It should be noted that the traditional soot blowing is generally through steam soot blowing or high-energy gas pulse soot blowing, both of which adopt high-temperature or high-pressure soot blowing ideas to remove the deposited or attached coal particles and pollutants in the pipeline. However, the above soot blowing scheme does not take into account the particularity of the acidic and corrosive deposits in the economizer, and is complicated to operate, high in cost, wastes manpower, and has poor soot blowing effect, and also causes damage to the pipeline.

[0024] Based on this, the present embodiment proposes to obtain the current soot deposition state of the economizer; generate a corresponding target soot blowing strategy according to the current soot deposition state; determine the running parameters and running time sequence of each sound wave generator according to the target soot blowing strategy; and control each sound wave generator to perform soot blowing on the economizer based on the running parameters and running time sequence, so that different soot blowing strategies are selected according to different soot deposition states, the soot blowing efficiency is improved, the sound wave generator is controlled to vibrate and remove the deposited material in the pipeline, and the pipeline blockage state is easily controlled.

[0025] The execution subject of the embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone or the like, or an electronic device, a control computer or the like capable of realizing the above functions. The embodiment and the following embodiments are described below by taking a control computer as an example.

[0026] Figure 1 A flowchart of a soot blowing control method of the present application is shown in FIG. 1. Referring to FIG. 1, the soot blowing control method comprises the following steps. Figure 1 In the embodiment, the soot blowing control method comprises the following steps. Step S10: Obtain the current soot deposition state of the economizer.

[0027] In the embodiment, the soot deposition state of the economizer can be one of fly ash deposition, condensation deposition and corrosion deposition. Fly ash deposition refers to the deposition of coal ash particles in the pipeline due to collision or friction or the like. Condensation deposition refers to the condensation of certain acid gases carried in the flue gas on the heat exchange surface to form condensation deposition. Corrosion deposition is mainly converted from acid particles contained in the flue gas and long-term attached condensation deposition, and corrosion deposition generally damages the pipeline and can even erode the pipeline to cause equipment shutdown.

[0028] It can be understood that the economizer is generally composed of multiple parallel serpentine pipelines. When high-temperature flue gas passes through the device, the heat of the high-temperature flue gas is transferred to the cooling water. The water is preheated before entering the boiler, thereby saving fuel and reducing the exhaust gas temperature to improve the efficiency of the boiler. Therefore, the heat exchange device is called an economizer. The operation principle is that high-temperature flue gas containing dust and acid particles is discharged from the furnace into the economizer flue at the tail of the boiler. Cold water is introduced into the serpentine pipeline of the economizer at the tail of the boiler. The cold water exchanges heat with the high-temperature flue gas on the surface of the serpentine pipeline. The temperature of the cold water is increased for use in other places. The high-temperature flue gas is discharged into the atmosphere after the temperature is reduced.

[0029] Step S20: Generate a corresponding target soot blowing strategy according to the current soot deposition state.

[0030] In order to solve the problem of soot deposition in the pipeline and improve the soot blowing efficiency, the embodiment sets a corresponding soot blowing strategy according to the different soot deposition states of the economizer.

[0031] For example, when the current soot deposition state of the economizer is fly ash deposition, the sound wave generator installed on the economizer is controlled to operate sequentially. When the current soot deposition state of the economizer is condensation deposition, the sound wave generator installed on the economizer is controlled to operate cooperatively. When the current soot deposition state of the economizer is corrosion deposition, the sound wave generator installed on the economizer is controlled to operate simultaneously.

[0032] Step S30: Determine the operation parameters and operation time sequence of each sound wave generator according to the target soot blowing strategy.

[0033] In the present embodiment, the operating parameters of the sound wave generator at least include: sound wave intensity, sound wave frequency, sound wave incidence angle, etc.

[0034] Due to different blowing strategies under different ash deposition states, the positions of the deposited ash faced are different, in order to improve the blowing efficiency, the running time sequence of each sound wave generator also exists difference.

[0035] Step S40: based on the operating parameters and the running time sequence, control each sound wave generator to blow ash on the economizer.

[0036] In the present embodiment, the sound wave generator on the economizer is generally four groups, its installation position is determined according to the equipment size of the economizer, in order to improve the blowing efficiency, the installation position of the sound wave generator is also analyzed and determined before blowing in the present embodiment.

[0037] Further, the blowing control method further comprises: acquire the equipment size data of the economizer; construct a three-dimensional space model of the economizer based on the equipment size data; based on the three-dimensional space model, perform stress distribution analysis to obtain a stress distribution map of the economizer; determine the installation position of the sound wave generator according to the stress distribution map of the economizer.

[0038] In specific implementation, the equipment size data at least includes the extreme length, width and height of the economizer, the shape of the heat dissipation pipeline, etc.; the three-dimensional space model is a one-to-one reduction digital twin model of the economizer, which can be used for blowing simulation analysis of various sulfides and nitrogen oxides.

[0039] The main role of stress distribution analysis is to determine the area with more deposits in the economizer and improve the accuracy of determining the blowing time of the economizer.

[0040] In the present embodiment, the economizer is directly connected to the high-temperature and high-pressure gas discharged from the boiler, but due to the insufficient pressure of the gas to the deposits in the pipeline, it is difficult to blow out the deposits, in the present embodiment, the fly ash deposition, condensation deposition and corrosion deposition are stripped from the inner wall of the pipeline by sound wave, so that the blowing of the pipeline can be realized without shutdown, and the efficiency of thermal power generation is improved.

[0041] The embodiment obtains the current ash deposition state of the coal economizer, generates a corresponding target soot blowing strategy according to the current ash deposition state, determines the operation parameters and operation timing of each acoustic wave generator according to the target soot blowing strategy, and controls each acoustic wave generator to blow ash of the coal economizer based on the operation parameters and operation timing, so that different soot blowing strategies are selected according to different ash deposition states, the soot blowing efficiency is improved, the acoustic wave generator is controlled to vibrate and remove the deposits blocking the pipeline, the pipeline blocking state is easily controlled, and the technical problems in the prior art, such as low soot blowing efficiency of the coal economizer in the thermal power generation process and inability to accurately control the pipeline blocking working condition, are avoided.

[0042] Based on the above embodiment, please refer to Figure 2 , step S40, comprising: Step S201: When the current ash deposition state of the coal economizer is fly ash deposition, the operation parameters of each acoustic wave generator are determined as first operation parameters.

[0043] Step S202: The first operation sequence of each acoustic wave generator is determined.

[0044] Step S203: Based on the first operation sequence and the first operation parameters, each acoustic wave generator is controlled to operate in sequence to generate vibration sound waves.

[0045] It should be noted that in the present embodiment and subsequent embodiments, the positions of the plurality of acoustic wave generators installed on the coal economizer are four groups, which are located on four edges of a cube with the coal economizer as the center and the limit size of the coal economizer as the boundary.

[0046] Since fly ash deposition is generally affected by collision or friction, it is deposited on the leeward slope of the air outlet side of the coal economizer, and the operation sequence of each acoustic wave generator in the fly ash deposition working condition is also related to the air inlet and air outlet of the coal economizer. Figure 3 For example, the acoustic wave generators of the coal economizer are acoustic wave generators back 1 and back 2 of the leeward slope of the air outlet side of the coal economizer, acoustic wave generators front 1 and front 2 of the windward slope of the air inlet side of the coal economizer, and the operation sequence of the acoustic wave generators in the fly ash deposition working condition is back 1, back 2, front 2, and front 1, or back 2, back 1, front 1, and front 2, that is, they are regularly started in clockwise or counterclockwise order.

[0047] Further, the soot blowing control method further comprises: When the current ash deposition state of the coal economizer is condensation deposition, the operation parameters of each acoustic wave generator are determined as second operation parameters; The air inlet and air outlet of the coal economizer are determined, and the initial acoustic wave generator and the remaining acoustic wave generator of each acoustic wave generator are determined according to the air inlet; According to the second operation parameters, the initial acoustic wave generator and the remaining acoustic wave generator are controlled to operate cooperatively to generate vibration sound waves.

[0048] Since the condensation deposition refers to that some acid gases carried in flue gas reach dew point at the heat exchange surface, condensation occurs, and condensation deposition is formed, which is more difficult to remove than fly ash deposition, and the main position of condensation deposition is also at the leeward side of the air outlet side of the economizer.

[0049] The initial sound wave generator refers to the sound wave generators back 1 and back 2 at the leeward side of the air outlet side of the economizer, and the remaining sound wave generator refers to the sound wave generators front 1 and front 2 at the windward side of the air inlet side of the economizer. Correspondingly, the cooperative operation of the initial sound wave generator and the remaining sound wave generator refers to that the sound wave generators back 1 and back 2 at the leeward side of the air outlet side of the economizer are controlled to run simultaneously for one period, and the sound wave generators front 1 and front 2 are closed; in the next period, the sound wave generators front 1 and front 2 at the windward side of the air inlet side of the economizer are opened, and the sound wave generators back 1 and back 2 are closed, so that the condensation deposition is removed by the greater vibration sound wave, and the energy consumption is saved.

[0050] Further, the cooperative operation of the initial sound wave generator and the remaining sound wave generator according to the second operation parameter respectively includes: Any sound wave generator of the initial sound wave generator or the remaining sound wave generator is continuously operated for a preset time length, and the other sound wave generator is kept closed; Correspondingly, the cooperative operation of the initial sound wave generator and the remaining sound wave generator according to the second operation parameter respectively includes: The initial sound wave generator is controlled to operate for a preset time length according to the second operation parameter, and the remaining sound wave generator is closed; or The remaining sound wave generator is controlled to operate for a preset time length according to the second operation parameter, and the initial sound wave generator is closed.

[0051] In a specific implementation, compared with the first operation parameter, the second operation parameter has the same incident angle, but the second sound wave intensity and the second sound wave frequency of the second operation parameter are greater than the first sound wave intensity and the first sound wave frequency of the first operation parameter.

[0052] Further, the ash deposition state of the economizer at least includes corrosion deposition; The soot blowing control method further includes: When the current ash deposition state of the economizer is corrosion deposition, the operation parameter of each sound wave generator is determined as a third operation parameter; Each sound wave generator is controlled to operate simultaneously according to the third operation parameter to generate a vibration sound wave.

[0053] The corrosion deposition is mainly converted from the acid particles contained in the flue gas and the condensation deposition attached for a long time, and the corrosion deposition generally damages the pipeline and even erodes the pipeline, causing the equipment to stop, and the location of the corrosion deposition is not limited to the leeward slope, and the windward slope also has corrosion deposition when the condensation deposition on the leeward slope is serious. Therefore, in order to improve the ability to remove the corrosion deposition, the embodiment simultaneously opens each acoustic generator to generate a vibrating sound wave to remove the deposition.

[0054] Specifically, the third operating parameter has the same incident angle as the second operating parameter, but the third sound wave intensity and the third sound wave frequency of the third operating parameter are greater than the second sound wave intensity and the second sound wave frequency of the second operating parameter.

[0055] The embodiment selects different soot blowing strategies and adopts different operating parameters to generate different degrees of vibrating sound waves under different soot accumulation conditions, thereby increasing the soot blowing efficiency and saving soot blowing energy efficiency, and accurately controlling the pipeline blockage condition.

[0056] The application also provides a soot blowing control device, please refer to Figure 4 The soot blowing control device comprises: An acquisition module 10 is configured to acquire a current soot accumulation state of the economizer.

[0057] A generation module 20 is configured to generate a target soot blowing strategy corresponding to the current soot accumulation state.

[0059] A soot blowing module 40 is configured to control the acoustic generators to blow the economizer based on the operating parameters and the operating time sequences.

[0060] The embodiment acquires the current soot accumulation state of the economizer, generates a target soot blowing strategy corresponding to the current soot accumulation state, determines operating parameters and operating time sequences of the acoustic generators according to the target soot blowing strategy, and controls the acoustic generators to blow the economizer based on the operating parameters and the operating time sequences, so that different soot blowing strategies are selected according to different soot accumulation states, the soot blowing efficiency is improved, the acoustic generators are controlled to vibrate and remove the deposition in the pipeline, the pipeline blockage state is easily controlled, and the technical problem that the soot blowing efficiency of the economizer in the thermal power generation process is low and the pipeline blockage condition cannot be accurately controlled in the prior art is avoided.

[0063] In an embodiment, the soot-blowing module 40 is further configured to control any acoustic generator of the initial acoustic generator or the remaining acoustic generators to operate for a preset time length, and control the other acoustic generator to remain closed; and accordingly, control the initial acoustic generator and the remaining acoustic generators to operate in coordination based on the second operation parameters, respectively, including: controlling the initial acoustic generator to operate for the preset time length and closing the remaining acoustic generators based on the second operation parameters; or controlling the remaining acoustic generators to operate for the preset time length and closing the initial acoustic generator based on the second operation parameters.
