[0002] Flue flow field design plays a vital role in flue gas treatment systems in thermal power generation, petrochemical, metallurgy and other industries. The uniformity of the flue flow field is directly related to the efficiency of the flue gas purification equipment, the energy consumption of the system and the service life of the equipment. In modern industrial production, flue gas treatment systems usually need to meet strict environmental protection standards.

Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0070] The following describes the design method and device of the flue flow field and the electronic equipment of the embodiments of the present disclosure with reference to the accompanying drawings.

[0071] Figure 1 A schematic flow chart of a method for designing a flue flow field provided in an embodiment of the present disclosure.

[0072] like Figure 1 As shown, the method comprises the following steps:

[0073] Step 101, acquiring system data of a flue gas treatment system, and performing flue opening design processing according to the system data to obtain target opening information; wherein the system data at least includes structural features of the flue gas treatment system.

[0074] In the disclosed embodiment, when designing the flue flow field, it is necessary to make holes in the flue of the flue gas treatment system. The specific hole making method and information need to be determined according to the structural characteristics of the flue gas treatment system, that is, the hole size and number of holes can be designed according to the characteristics of the engineering modification. When making holes, the hole position is generally located at the rear wall.

[0075] Among them, it is necessary to collect all necessary data related to the flue gas treatment system, namely system data. System data is the basis for subsequent design, and its accuracy directly affects the effectiveness of the opening design. System data can be obtained in a variety of ways, including but not limited to: on-site measurements, information provided by equipment manufacturers, design drawings, historical operation data, etc. System data should at least include the structural characteristics of the flue gas treatment system. Structural characteristics refer to the physical layout and construction details of the system, which are crucial to the design of flue openings. Structural characteristics include but are not limited to: flue dimensions (such as length, diameter, wall thickness), material type, connection method, location and size of internal components (such as expansion joints, guide plates), and flue support structure.

[0076] The goal of the opening design process is to determine the optimal position, size and number of the openings to optimize the flow field distribution in the flue, reduce eddy currents and dead zones, and improve the flow efficiency of the flue gas. The target opening information includes but is not limited to: the specific position, size (such as diameter), shape and number of each opening. The target opening information ensures the accuracy and practicality of the flue opening design.

[0077] Step 102, determining the smoke extraction point information of the smoke duct in the smoke treatment system according to the target opening information, and performing flow velocity simulation processing of the smoke flow field of the smoke treatment system based on the smoke extraction point to obtain smoke flow field simulation information.

[0078] In the embodiment of the present disclosure, there is no less than one flue gas extraction point on each side of the flue of the flue treatment system. The flue gas extraction point information is the flue gas extraction point of the flue in the flue treatment system further clarified on the basis of the target opening information. The flue gas extraction point is usually a position in the flue for installing a flue gas sampling device or connecting to subsequent treatment equipment (such as a desulfurization or denitrification device).

[0079] Among them, when performing the flow velocity simulation processing of the flue flow field, the following methods can be used but are not limited to: the smoke extraction point determined according to the smoke extraction point information is used as the starting point of the flow velocity simulation (that is, the flow velocity simulation of the flue flow field under various working conditions after the smoke extraction point is performed). The position of the smoke extraction point is crucial to the accuracy of the simulation results. The smoke extraction point will affect the flow path and distribution of the smoke in the flue. At the same time, computational fluid dynamics (CFD) or other fluid dynamics simulation tools are used to simulate the smoke flow in the flue of the flue in the flue treatment system based on the position of the smoke extraction point. Factors considered in the simulation process include but are not limited to: physical properties of smoke, geometric shape of the flue, smoke flow, etc.

[0080] The flue flow field simulation information is a series of data and information about the flow state of smoke in the flue through flow velocity simulation processing. The flue flow field simulation information includes but is not limited to: Flow velocity distribution: showing the magnitude and direction of the flue flow velocity at each point in the flue. Pressure distribution: revealing the pressure changes at each point in the flue. Streamline diagram: showing the flow path of the smoke to help identify vortices and dead zones.

[0081] Flue flow field simulation information is of great significance for evaluating the rationality of flue design, predicting the performance of flue in actual operation, and guiding the optimization design of flue structure. The method of obtaining flue flow field simulation information through velocity simulation processing helps to ensure that the design of flue gas treatment system is more scientific and efficient, thereby improving the operation performance and reliability of the whole system.

[0082] Step 103, performing flue flow field design processing on the flue gas treatment system according to the flue flow field simulation information to obtain a target flue flow field; wherein the target flue flow field is used to ensure uniform flue flow velocity through an additional preset guide plate.

[0083] In the disclosed embodiment, the preset guide plate is a custom-set guide plate. When determining the target flue flow field, the guide plate is installed to ensure that the flow velocity of each flue after the extraction point, the denitrification entrance point, and the mixing point is uniform. This prevents excessive local flow velocity from causing local wear of the flue, expansion joint, and catalyst.

[0084] Among them, the flue flow field design processing refers to a series of design adjustments to the flue based on the flue flow field simulation information, including but not limited to: changing the geometric shape of the flue, adjusting the position or size of the flue gas inlet and outlet, optimizing the internal structure of the flue, etc. The purpose of the flue flow field design processing is to improve the flue flow field and make it more uniform and efficient.

[0085] The target flue flow field is a flue flow field that achieves a predetermined design target after design processing, that is, a flue flow field with uniform flue gas flow velocity, no obvious vortex and dead zone, and minimized flue pressure loss. The target flue flow field can ensure that the flue gas treatment system operates in the best state and improve the efficiency of subsequent treatment links such as desulfurization and denitrification.

[0086] At the same time, in order to achieve the target flue flow field, it is necessary to install a preset guide plate inside the flue. The function of the preset guide plate is to guide the flue gas flow, reduce the unevenness and vortex in the flow, and ensure that the flue gas flow rate is as uniform as possible over the entire flue cross section. By installing a preset guide plate, the flow path of the flue gas can be effectively controlled to avoid local high-speed and low-speed areas, thereby improving the overall performance and reliability of the flue gas treatment system. The method of optimizing the flue flow field by designing and installing guide plates ensures the uniformity of the flue flow rate, which is of great significance for improving the efficiency of the flue gas treatment system and reducing energy consumption.

[0087] The design method of flue flow field provided by the present disclosure obtains system data of a flue gas treatment system, and performs flue opening design processing according to the system data to obtain target opening information; wherein the system data at least includes the structural characteristics of the flue gas treatment system; the smoke extraction point information of the flue gas duct in the flue gas treatment system is determined according to the target opening information, and the flow velocity simulation processing of the flue flow field of the flue gas treatment system is performed based on the smoke extraction point to obtain flue flow field simulation information; the flue flow field design processing of the flue gas treatment system is performed according to the flue flow field simulation information to obtain a target flue flow field; wherein the target flue flow field is used to ensure uniform flue flow velocity through an additional preset guide plate. Compared with the related art, the embodiment of the present disclosure can ensure uniform flue flow field, reduce wear and improve flue gas treatment efficiency by designing the flue flow field according to the smoke extraction point information and the flue flow field simulation information, and ensuring uniform flue flow velocity through an additional preset guide plate.

[0088] In one implementable manner of the embodiment of the present disclosure, when performing flue flow field design processing on the flue gas treatment system, it can also be implemented in but not limited to the following manner: determine the bypass flue and the main flue of the flue gas treatment system; perform flue flow field design processing on the bypass flue and the main flue respectively according to the flue flow field simulation information to obtain a first flue flow field corresponding to the bypass flue and a second flue flow field corresponding to the main flue; perform flow field interference analysis on the first flue flow field and the second flue flow field to obtain an interference analysis result; when it is determined according to the interference analysis result that the first flue flow field does not interfere with the second flue flow field, the first flue flow field and the second flue flow field are determined as the target flue flow field.

[0089] In the disclosed embodiment, when designing the flue flow field, the flow field design of the bypass flue shall not change the characteristics of the flue flow field of the main flue, and the guide plate design shall not conflict with the guide plate at the denitrification inlet point. If necessary, the guide plate can be modified to a certain extent.

[0090] Among them, in the flue gas treatment system, the bypass flue and the main flue are two different flow paths. The bypass flue is usually used for auxiliary treatment processes such as flue gas denitrification, while the main flue is the main flow channel for flue gas. Therefore, it is necessary to clarify the location and function of these two flues. After that, the bypass flue and the main flue are designed and processed separately through the flue flow field simulation information, including but not limited to: adjusting the flue shape and size, adding guide plates, etc., in order to optimize their respective flow fields. The first flue flow field and the second flue flow field refer to the flow field states of the bypass flue and the main flue after the design processing.

[0091] At the same time, flow field interference analysis is performed on the flow field of the first flue and the flow field of the second flue. The flow field interference analysis is used to evaluate whether there is mutual influence between the flow fields of the bypass flue and the main flue. Through analysis, it can be determined whether the flow fields of the bypass flue and the main flue interfere with each other, and the extent of such interference. If the flow field interference analysis results show that the flow field of the bypass flue (the first flue flow field) does not interfere with the flow field of the main flue (the second flue flow field), it can be confirmed that the flow field of the first flue and the second flue are the target flue flow fields that meet the design requirements. It means that the flow field design of the bypass flue and the main flue is successful, and they can work independently in actual applications without affecting each other, thereby ensuring the overall performance of the flue gas treatment system.

[0092] The disclosed embodiment performs independent flow field design processing on the bypass flue and the main flue, and ensures the rationality of the flow field design through flow field interference analysis, which helps to improve the design efficiency and operational stability of the flue gas treatment system.

[0093] In one possible implementation of the embodiment of the present disclosure, when the flue flow field design processing is performed on the bypass flue and the main flue respectively, it can also be implemented in but not limited to the following methods: according to the flue flow field simulation information and the flue gas extraction point information, the guide plate design processing of the flue gas extraction point of the bypass flue and the main flue is performed respectively to obtain the first guide plate information; the denitrification entry point information and the mixing point information of the flue gas treatment system are obtained, and according to the flue flow field simulation information and the denitrification entry point information, the bypass flue is respectively designed and processed. and the guide plate design processing of the denitrification entrance point of the main flue to obtain the second guide plate information; according to the flue flow field simulation information and the mixing point information, the guide plate design processing of the mixing point of the bypass flue and the main flue is respectively performed to obtain the third guide plate information; according to the flue flow field simulation information, the first guide plate information, the second guide plate information and the third guide plate information, the flue flow field design processing of the bypass flue and the main flue is respectively performed to obtain the first flue flow field and the second flue flow field.

[0094] In the embodiment of the present disclosure, the first guide plate information, the second guide plate information and the third guide plate information can be used to design the guide plates for the flue gas extraction point, the denitrification entry point and the mixing point of the bypass flue and the main flue, respectively.

[0095] Among them, the denitrification entry point information refers to the entry position information of the flue gas entering the denitrification treatment equipment (such as: Selective Catalytic Reduction (SCR) system or Selective Non-Catalytic Reduction (SNCR) system) in the flue gas treatment system. The denitrification entry point information includes but is not limited to: Position: the specific entry position of the denitrification equipment (such as: the position coordinates relative to the entire flue gas treatment system). Size: the geometric dimensions of the inlet (such as: width, height and shape). Flow rate: the flow rate of the flue gas when it enters the denitrification equipment. Temperature: the temperature of the flue gas at the inlet (temperature is a key parameter affecting the denitrification efficiency and catalyst performance). Concentration: the concentration of nitrogen oxides (NOx) in the flue gas and other major pollutants that need to be reduced in the denitrification process.

[0096] Mixing point information refers to the location information where different flue gas flows in the flue gas treatment system meet and mix in the flue. In the flue gas treatment system, the mixing point usually refers to the point where the flue gas that has passed through different treatment paths (such as bypass and main path) reunite. Mixing point information includes but is not limited to: Position: The specific location of the mixing point in the flue system. Flow state: The flow state of the flue gas at the mixing point (such as laminar flow or turbulent flow). Flow velocity distribution: The flow velocity distribution of different flue gas flows at the mixing point. Temperature distribution: The temperature distribution of the flue gas at the mixing point. Pollutant concentration distribution: The concentration distribution of different pollutants at the mixing point (such as NOx, SO2, particulate matter, etc.).

[0097] The first guide plate information, the second guide plate information and the third guide plate information respectively include design parameters such as shape, size, position and angle of guide plates at different positions.

[0098] In an implementable manner of the embodiment of the present disclosure, the first guide plate information, the second guide plate information and the third guide plate information package are also used for: the first guide plate information is used to install the preset guide plate at the flue gas extraction points of the bypass flue and the main flue; the second guide plate information is used to install the preset guide plate at the denitrification entry points of the bypass flue and the main flue; the third guide plate information is used to install the preset guide plate at the mixing point of the bypass flue and the main flue.

[0099] In one implementable manner of the disclosed embodiment, after the design and processing of the smoke flow field, it is also necessary to design an anti-wear guide plate inside the flue expansion joint to prevent smoke from scouring the expansion joint. Therefore, in order to ensure that the flue expansion joint can effectively protect the inner wall of the flue from wear while compensating for the flue expansion, thereby extending the service life of the system and improving the operating efficiency and safety of the system, the following method may also be used but is not limited to: determine the flue expansion joint corresponding to each flue in the flue gas treatment system, and design a guide plate inside each of the flue expansion joints to obtain fourth guide plate information; wherein the fourth guide plate information at least includes installing an anti-wear guide plate inside each of the flue expansion joints.

[0100] In the embodiment of the present disclosure, in the flue gas treatment system, the flue expansion joint is an important component for compensating for the length change of the flue caused by temperature change. Each flue may be equipped with one or more expansion joints according to its location and functional requirements. The purpose of the internal guide plate design of the flue expansion joint is to improve the flue gas flow characteristics, reduce the wear caused by the flue gas flow, and provide a uniform flow field distribution.

The fourth guide plate information includes but is not limited to: the size of the guide plate: including length, width and thickness, etc. The shape of the guide plate: the shape of the guide plate is designed according to the internal structure and flow field characteristics of the flue expansion joint.

[0102] The anti-wear guide plate is a specially designed guide plate, the purpose of which is to reduce the wear of the solid particles in the flue gas on the inner wall of the flue. The characteristics of the anti-wear guide plate include but are not limited to: Wear-resistant material: Made of wear-resistant coating or integral wear-resistant material. Structural design: By optimizing the geometric shape of the guide plate, the flue gas flow is guided to reduce the impact and wear of particles. Installation method: Ensure that the guide plate can be firmly installed inside the expansion joint to withstand the influence of flue gas flow dynamics and thermal expansion.

[0103] In one implementable manner of the embodiment of the present disclosure, after the design and processing of the smoke flow field, it is also necessary to design measures to prevent ash accumulation in the horizontal flue and the mixing area flue after the flue gas extraction point. Therefore, in order to reduce the risk of flue blockage and improve the overall efficiency and reliability of the flue gas treatment system, the following method may also be used but is not limited to: determine the first flue based on the flue gas extraction point information, and perform anti-ash accumulation treatment on the first flue; wherein, the first flue is the flue after the flue gas extraction point in the flue treatment system.

[0104] In one implementable manner of the disclosed embodiment, after the design processing of the smoke flow field, it is also necessary to check whether the ash discharge frequency of the original denitrification inlet ash hopper is met. Therefore, in order to ensure that the ash hopper in the flue gas treatment system can effectively discharge ash according to the design requirements and avoid system failure or performance degradation caused by dust accumulation, thereby ensuring the normal operation of the entire system, the following method may also be adopted but is not limited to: perform ash discharge frequency detection processing on the ash hopper at the denitrification inlet point to obtain a detection result; when it is determined according to the detection result that the ash discharge frequency of the ash hopper meets the preset frequency condition, the ash discharge hopper is determined to be an available ash discharge hopper; when it is determined according to the detection result that the ash discharge frequency of the ash hopper does not meet the preset frequency condition, the ash discharge hopper is determined to be an unavailable ash discharge hopper, and the ash hopper is designed and processed according to the denitrification inlet point information to obtain a target ash hopper.

[0105] In the embodiment of the present disclosure, the preset frequency condition is a dust removal frequency standard pre-set according to the design and operation requirements of the flue gas treatment system. The preset frequency condition ensures that the ash hopper can effectively remove the collected dust and prevent dust accumulation from affecting system performance.

[0106] In one implementable method of the disclosed embodiment, after the smoke flow field is designed, it is also necessary to take anti-wear measures for the heating surface of the extraction point and to design the anti-wear of the overall bypass flue. Therefore, in order to improve the wear resistance of the flue gas treatment system pipeline, extend the service life of the pipeline, and reduce the downtime and maintenance costs caused by wear, the following method can also be used: perform anti-wear design on all pipelines of the flue gas treatment system.

[0107] In the disclosed embodiment, since the pipes in the flue gas treatment system operate in a high temperature and high flow rate flue gas environment, the flue gas often contains a certain amount of solid particles. These particles will cause wear on the inner wall of the pipe during the flow of the flue gas, which may cause the pipe wall to become thinner, leak or even rupture under long-term action. Therefore, anti-wear design treatment is required.

[0108] In summary, the embodiments of the present disclosure can achieve the following technical effects:

[0109] 1. The embodiment of the present disclosure designs the flue flow field according to the flue gas extraction point information and the flue flow field simulation information, and ensures uniform flue flow velocity by installing preset guide plates, thereby ensuring uniform flue flow field, reducing wear and improving flue gas treatment efficiency.
