Description

Technical Field

[0001] This invention belongs to the field of desulfurization technology, specifically relating to a flue gas desulfurization and energy-saving operation equipment cabinet for thermal power plants. Background Technology

[0002] In related technologies, the variable frequency system for wet desulfurization slurry circulating pumps in thermal power plants only has variable frequency speed regulation and logic control functions, and lacks dust filtration, separation, or removal structures. Therefore, it cannot intercept flue gas dust, slurry solid impurities, and condensation mist entering the cabinet. Furthermore, the cabinet lacks filtration and automatic cleaning mechanisms, which can easily lead to dust accumulation on electrical components, blocked air ducts, and dirt buildup during long-term operation. This makes self-maintenance and cleaning difficult, resulting in poor heat dissipation, accelerated insulation aging, reduced operational stability and energy-saving effects, and increased manual maintenance burden. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention propose a flue gas desulfurization and energy-saving operation equipment cabinet for thermal power plants. This cabinet can achieve air intake filtration to prevent impurities from entering the cabinet and achieve cooling of the cabinet, ensuring the stable operation of electrical equipment.

[0004] The flue gas desulfurization and energy-saving operation equipment cabinet for thermal power plants according to an embodiment of the present invention includes a cabinet body, a first filter component, a fan, a second filter component, and a cleaning component. The cabinet body is provided with a cabinet door, and the cabinet door has an air inlet. The first filter component covers the air inlet. The fan is located inside the cabinet body and corresponds to the air inlet. The fan is used to allow airflow from outside the cabinet body to enter the interior of the cabinet body. The second filter component is located inside the cabinet body and is located on the air outlet side of the fan. The cleaning component is located inside the cabinet body and includes a scraper that can contact the second filter component. The scraper is movable to clean the second filter component.

[0005] The flue gas desulfurization and energy-saving operation equipment cabinet for thermal power plants in this embodiment of the invention forms a two-stage purification path by setting a first filter component at the air inlet and a second filter component on the fan outlet side. This effectively traps dust and impurities of different particle sizes, reducing the risk of contamination to electrical components. Simultaneously, a scraper located inside the cabinet can move and scrape the second filter component, promptly removing accumulated dust, preventing filter clogging, and maintaining smooth airflow. This solves the problems of dust accumulation, duct blockage, and poor heat dissipation caused by the lack of dust interception and self-cleaning capabilities in existing equipment cabinets, facilitating long-term cleanliness and ventilation within the cabinet.

[0006] In some embodiments, the number of the first filter elements is multiple, and the first filter element is a plate-shaped filter screen structure, with multiple first filter elements arranged side by side along the thickness direction of its plate surface.

[0008] In some embodiments, the flue gas desulfurization and energy consumption reduction operation equipment cabinet for thermal power plants further includes a first partition plate, which is placed inside the cabinet and divides the cabinet into a first chamber and a second chamber. The first partition plate is provided with a gas passage connecting the first chamber and the second chamber. The fan and the first filter component are located in the first chamber, the second filter component and the cleaning component are located in the second chamber, and the second filter component covers the gas passage.

[0009] In some embodiments, the second filtering component includes a filter box disposed on the first partition and located in the second chamber. The interior of the filter box is in communication with the gas channel. The side wall of the filter box facing the gas channel is a working side wall. At least the working side wall of the filter box is a filter screen structure.

[0010] In some embodiments, the scraping surface of the scraper is in contact with the outer wall surface of the working sidewall.

[0011] In some embodiments, the cleaning assembly further includes a drive component for driving the scraper to reciprocate along the outer wall surface of the working sidewall.

[0012] In some embodiments, the fan includes a motor component and a fan blade component. A second partition is provided in the first chamber, the second partition being located between the motor component and the fan blade component. The second partition divides the first chamber into an airflow chamber and an installation chamber, wherein the first filter component and the fan blade component are located in the airflow chamber, the gas passage is in communication with the airflow chamber, and the motor component is located in the installation chamber.

[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] like Figures 1-4 As shown, the flue gas desulfurization and energy consumption reduction operation equipment cabinet of the present invention includes a cabinet body 1, a first filter component 2, a fan 3, a second filter component 4, and a cleaning component 5. The cabinet body 1 is provided with a cabinet door 11, and an air inlet 13 is opened on the cabinet door 11. The first filter component 2 covers the air inlet 13. The fan 3 is located inside the cabinet body 1 and corresponds to the air inlet 13. The fan 3 is used to allow the airflow outside the cabinet body 1 to enter the interior of the cabinet body 1. The second filter component 4 is located inside the cabinet body 1 and is located on the air outlet side of the fan 3. The cleaning component 5 is located inside the cabinet body 1 and includes a scraper 51 that can contact the second filter component 4. The scraper 51 is movable to clean the second filter component 4.

[0025] The flue gas desulfurization and energy consumption reduction operation equipment cabinet of the present invention, by setting a first filter component 2 at the air inlet 13 of the cabinet body 1 and cooperating with the internal second filter component 4, and configuring a movable scraper 51 for cleaning the internal second filter component 4, can perform two-stage purification of the external airflow entering the cabinet body 1, and automatically remove dust and impurities accumulated on the internal filter screen, which helps to maintain the cleanliness of the cabinet and the long-term stability of ventilation and heat dissipation.

[0026] Specifically, the flue gas desulfurization and energy-saving operation equipment cabinet for thermal power plants according to this embodiment of the invention includes a cabinet body 1, and a cabinet door 11 is installed on the front side of the cabinet body 1. Multiple air inlets 13 arranged side-by-side are opened in the lower area of ​​the cabinet door 11, through which outside air is introduced into the cabinet. A first filter element 2 is covered and installed at the air inlet 13. The first filter element 2 is typically a plate-shaped filter screen, which can trap large particles of dust and fly ash outside the cabinet body 1 when airflow passes through, achieving initial barrier effect.

[0027] Inside the cabinet 1, at the position corresponding to the air inlet 13, a fan 3 is installed. After the fan 3 is started, it creates negative pressure, drawing external cold air through the air inlet 13 and the first filter component 2 in sequence, and entering the cabinet 1 along a preset flow path.

[0028] A second filter element 4 is provided on the outlet side of the fan 3. This second filter element 4 is located downstream of the fan 3 and is used to further intercept the airflow that has already been filtered once, capturing fine particulate matter, condensation, and water mist. An airflow expansion space is maintained between the second filter element 4 and the fan 3, so that the gas is more evenly distributed when passing through the second filter element 4, thereby improving the filtration effect.

[0029] The cabinet 1 is also equipped with a cleaning component 5, which includes a scraper 51. The scraper 51 can be set close to the air outlet surface of the second filter component 4 and can move horizontally along the surface under drive. It uses the edge scraping action to peel off the dust, sludge, and scale adhering to the filter screen surface, so that they fall off and collect in the collection area, preventing the filter holes of the second filter component 4 from becoming clogged and maintaining the ventilation resistance within the design range.

[0030] In some embodiments, there are multiple first filter elements 2, and the first filter element 2 is a plate-shaped filter screen structure, with multiple first filter elements 2 arranged side by side along the thickness direction of its plate surface.

[0031] In some embodiments, the flue gas desulfurization and energy consumption reduction operation equipment cabinet of a thermal power plant further includes a mounting slot 6, which is located on the inner side of the cabinet door 11, and a plurality of first filter components 2 are slidably installed in the mounting slot 6.

[0032] In this embodiment, there are multiple first filter elements 2, each of which is a plate-shaped filter structure. These multiple first filter elements 2 are arranged side-by-side along the thickness direction of their respective plates, with a certain airflow gap between them, forming a layered barrier. This multi-layered plate-shaped filter arrangement can intercept the intake air step by step. Even if larger particles are attached to the surface of the front filter, the subsequent filters can still capture fine dust, improving the overall interception capacity and continuous purification capability of the intake side for dust, particulate matter, and fly ash, and reducing the risk of a rapid increase in intake resistance due to easy clogging of a single filter layer.

[0033] In addition, to ensure reliable positioning and convenient installation and removal of multiple first filter components 2 on the cabinet door 11, a mounting groove 6 is provided on the inner side of the cabinet door 11. The mounting groove 6 has guide channels extending in the vertical or horizontal direction. The edges of multiple plate-shaped first filter components 2 are inserted into the grooves one by one and can slide along the channels to achieve sliding installation. When it is necessary to replace or clean a filter screen, the operator can open the cabinet door 11 and directly pull out the corresponding first filter component 2 along the mounting groove 6 without disassembling bolts or moving other components, which reduces the difficulty of daily cleaning and filter media replacement and helps to keep the air inlet 13 unobstructed for a long time.

[0034] In some embodiments, the flue gas desulfurization and energy consumption reduction operation equipment cabinet of a thermal power plant further includes a first partition 7, which is placed inside the cabinet 1 and divides the cabinet 1 into a first chamber 8 and a second chamber 9. The first partition 7 is provided with a gas channel connecting the first chamber 8 and the second chamber 9. The fan 3 and the first filter component 2 are located in the first chamber 8, and the second filter component 4 and the cleaning component 5 are located in the second chamber 9, with the second filter component 4 covering the gas channel.

[0035] In some embodiments, the second filter component 4 includes a filter box 52, which is disposed on the first partition 7 and located in the second chamber 9. The interior of the filter box 52 is in communication with the gas channel. The side wall of the filter box 52 that is directly opposite the gas channel is the working side wall. At least the working side wall of the filter box 52 is a filter screen structure.

[0036] In some embodiments, the scraping working surface of the scraper 51 contacts the outer wall surface of the working sidewall.

[0037] In some embodiments, the cleaning component 5 further includes a drive component 53 for driving the scraper 51 to reciprocate along the outer wall surface of the working sidewall.

[0038] In this embodiment, the space is divided into two chambers by setting a first partition 7 inside the cabinet 1, and the second filter component 4 is constructed as a filter box 52 with a working side wall. This allows the airflow to flow directionally between the chambers and undergo secondary filtration. At the same time, the scraper 51 moves back and forth against the outer wall of the working side wall to clean it. This continuously removes the trapped dust, particulate matter and flocculation, preventing the mesh of the working side wall from becoming clogged and ensuring that the airflow channel remains unobstructed for a long time. This solves the problem of increased ventilation resistance and decreased heat dissipation capacity caused by the accumulation of dirt on the internal filter screen, and reduces the frequency of manual cleaning.

[0039] Specifically, a first partition 7 is fixed inside the cabinet 1, dividing the inner cavity of the cabinet 1 into two independent spaces: a first chamber 8 and a second chamber 9. An air passage is provided on the first partition 7, connecting the first chamber 8 and the second chamber 9, allowing airflow to flow directionally from one chamber to the other. The fan 3 and the first filter element 2 are both located in the first chamber 8. After being pressurized by the fan 3, the airflow must pass through the air passage to enter the second chamber 9. The second filter element 4 and the cleaning assembly 5 are located in the second chamber 9, with the second filter element 4 covering the outlet side of the air passage, thus performing secondary interception of the passing airflow.

[0040] The second filter element 4 includes a filter box 52, which is mounted and fixed on the first partition 7 and is completely located within the interior space of the second chamber 9. The interior space of the filter box 52 is in communication with the gas passage. Typically, the filter box 52 can be configured with one side open, which is directly fixed to the first partition 7 to achieve communication between the gas passage and the interior of the filter box 52.

[0041] The gas flowing into the first chamber 8 and the gas channel diffuses and slows down within the chamber before seeping outward from the side wall of the chamber. Of the various side walls of the filter chamber 52, the side wall directly facing the direction of the incoming airflow through the gas channel is defined as the working side wall. At least this working side wall employs a filter screen structure, becoming the main outlet surface for the airflow exiting the filter chamber 52 and entering the second chamber 9. Most dust and impurities are trapped here on the inner or outer wall surface. Alternatively, the other side walls of the filter chamber 52 can also typically be configured with filter screen structures to increase the filtration area.

[0042] The scraper 51 has a scraping working surface adapted to the outer wall surface of the working sidewall, which maintains close contact with the outer wall surface of the working sidewall. The cleaning assembly 5 also includes a drive component 53, which can be a reciprocating motor or a similar linear drive mechanism. The drive component 53 is mounted on the first partition 7, and its output end is connected to the scraper 51, enabling the scraper 51 to reciprocate along the outer wall surface of the working sidewall. During each reciprocating motion, the scraping working surface of the scraper 51 pushes and scrapes the outer wall surface of the working sidewall once, scraping off the dust, solidified slurry particles, and oily concretions attached to the mesh surface. The detached material falls into the collection area of ​​the filter box 52.

[0043] In some embodiments, the fan 3 includes a motor component and a fan blade component. A second partition is provided in the first chamber 8, which is located between the motor component and the fan blade component. The second partition divides the first chamber 8 into an airflow chamber and an installation chamber. The first filter component 2 and the fan blade component are located in the airflow chamber, and the gas passage is connected to the airflow chamber. The motor component is located in the installation chamber.

[0044] In some embodiments, the cabinet 1 is provided with an inspection door 12, which corresponds to the motor component.

[0045] In this embodiment, a second partition is installed in the first chamber 8 where the fan 3 is located to isolate the motor components and the fan blade components in different chambers, and a corresponding maintenance door 12 is provided for the motor components. This allows the motor to operate in a clean and sealed environment, completely avoiding the corrosion of dusty airflow and acidic moisture. At the same time, in case of failure, the maintenance door 12 can be quickly opened for targeted maintenance, reducing the workload of maintenance and disassembly and the downtime.

[0046] Specifically, a second partition is fixed inside the first chamber 8, located between the motor component and the fan blade component of the fan 3. The edge of the second partition is sealed to the inner wall of the first chamber 8, thus dividing the first chamber 8 into two independent areas: an airflow chamber and an installation chamber. The first filter component 2 and the fan blade component are located together in the airflow chamber. The gas passage on the first partition 7 is directly connected to this airflow chamber, and the pre-filtered air is pressurized by the fan blade component and directly sent into the gas passage. The motor component is installed in the closed installation chamber, and its shaft passes through a shaft hole opened in the second partition. A sealing ring is installed at the shaft hole to prevent dust-laden gas in the airflow chamber from seeping into the installation chamber, thus avoiding dust abrasion of the motor insulation layer, corrosion of the windings, or blockage of the motor's heat dissipation duct.

[0047] An inspection door 12 is located on the cabinet 1, directly opposite the installation chamber. The inspection door 12 is fixed to the side or rear wall of the cabinet 1 and can be opened. When closed, the inspection door 12 remains flush with the cabinet 1 and presses the sealing strip tightly, maintaining the overall protection level of the cabinet 1. When the motor malfunctions and needs repair or replacement, the operator only needs to open the inspection door 12 to directly access the motor components without disassembling the internal partitions, fan blade assemblies, or other connecting pipes, making the maintenance process simple and direct.

[0048] In some embodiments, the air intake 13 is an air intake grille structure.

[0049] In some embodiments, the cabinet 1 is provided with a detection component, at least a portion of which is used to detect the temperature data of the cabinet 1.

[0050] In some embodiments, the cabinet 1 is provided with an air outlet, which is connected to the second chamber 9.

[0051] In this embodiment, the air inlet 13 of the equipment cabinet adopts an air inlet grille structure, the cabinet body 1 is equipped with a detection component to monitor the temperature, and the cabinet body 1 is provided with an air outlet that communicates with the second chamber 9, thereby forming a more complete configuration in terms of air intake protection, operation status monitoring and exhaust path, which is conducive to early detection of abnormal temperature rise in the cabinet, avoiding local overheating, and maintaining smooth airflow circulation.

[0052] In the construction of the air inlet 13, the air inlet 13 is composed of multiple crisscrossing grille bars forming an air intake grille structure, with ventilation gaps left between the grille bars. Outside air must first pass through these grille gaps before reaching the first filter element 2. The grille itself can initially block large flying lint, debris, or external physical impacts from damaging the filter screen, while making the air intake distribution more uniform, avoiding airflow concentration in local areas of the filter screen, and extending the effective service life of the first filter element 2.

[0053] The cabinet 1 is equipped with detection components, at least some of which are used to detect the temperature data of the cabinet 1. These detection components can be thermocouples or resistance temperature detectors (RTDs) and are located in key heat-generating areas such as the second chamber 9 or the installation chamber. The detection components transmit the temperature signal to an external controller or check table in real time. When the temperature exceeds a preset threshold, the operator can adjust the speed of the fan 3 or check whether the filter components are blocked in time to prevent the electrical components from aging due to long-term overheating or causing control failure.

[0054] The cabinet 1 is also equipped with an air outlet, which is directly connected to the second chamber 9, serving to exhaust and relieve pressure. After passing through the second filter element 4, the clean airflow absorbs the heat emitted by the equipment inside the cabinet and is then discharged outside the cabinet through the air outlet, completing the entire forced ventilation cycle. The air outlet is positioned higher than the air inlet 13, taking advantage of the natural upward trend of hot air to make heat dissipation and exhaust more efficient.

[0055] In some specific embodiments, the cabinet door 11 of the cabinet 1 is equipped with a display instrument to directly display data such as internal temperature, pressure and the operating status of electrical equipment. The bottom of the cabinet 1 is equipped with pads to reduce the overall vibration caused by the fan 3.
