Description

Technical Field

[0001] This utility model relates to the field of desulfurization and denitrification technology, specifically to a dust removal and waste discharge device for desulfurization and denitrification. Background Technology

[0002] Currently, desulfurization and denitrification technologies on the market mainly include wet desulfurization, dry desulfurization, selective catalytic reduction, and selective non-catalytic reduction. The application of these technologies has greatly reduced the emissions of sulfur dioxide and nitrogen oxides, which is of great significance for improving air quality. However, in practical applications, since the treated gas contains a large amount of particulate dust, how to efficiently remove it has become an important research topic. Currently, commonly used dust removal methods mainly include electrostatic precipitators, bag filters, and cyclone separators.

[0003] For example, a Chinese patent (publication number: CN211146532U) discloses an integrated device for flue gas desulfurization, denitrification, and dust removal. A desulfurization and cooling device is installed on the right side of the flue gas conveying pipe, a denitrification and dust removal device is installed above the desulfurization and cooling device, and a wastewater recovery tank is installed below the desulfurization and cooling device. A first flue gas outlet is fixedly installed on the upper surface of the denitrification and dust removal device, a second liquid inlet is fixedly installed on the upper surface of the desulfurizing agent storage tank, and a second liquid inlet is fixedly installed on the left side of the desulfurizing agent storage tank. A valve is fixedly installed on the side of the second liquid inlet. The denitrification and dust removal device can filter and adsorb nitrates and dust in the flue gas, facilitating the collection of nitrate and dust waste for unified harmless treatment. The desulfurization and cooling device uses flue gas to drive a rotating rod, increasing airflow and allowing the desulfurizing agent to fully contact and react with the flue gas, improving desulfurization efficiency and preventing wastewater discharge from polluting the environment.

[0004] This patent improves the contact effect between the desulfurizing agent and the flue gas by rotating the rotating rod through the flue gas, thereby increasing the desulfurization efficiency. However, the dust removal effect is poor when the flue gas is filtered and adsorbed by the denitrification and dust removal device. Therefore, a dust removal and waste discharge device for desulfurization and denitrification is proposed to solve the above-mentioned problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1In this embodiment, a dust removal and waste discharge device for desulfurization and denitrification includes a base plate 1. A preheating chamber 2, a collection bin 3, and a dust removal box 4 are fixed on the top of the base plate 1. A pipeline 5 is connected to the right side of the preheating chamber 2. A solenoid valve 6 is fixed to the outside of the pipeline 5. A reaction tower 7 is connected to the top of the preheating chamber 2 through the pipeline 5. A cooling tower 8 is connected to the top of the reaction tower 7 through the pipeline 5.

[0032] It is understandable that the installation of preheating chamber 2, reaction tower 7 and cooling tower 8 facilitates the desulfurization and denitrification of the gas, thereby improving the desulfurization and denitrification effect of the device and enhancing the overall performance of the device.

[0033] It is also understandable that the top of the storage compartment 3 is fixed with cyclone separators 9 connected to the dust collection box 4 and the cooling tower 8 respectively through pipelines 5 on the left and right sides. The right side of the storage compartment 3 is slidably connected with a movable box 10. The inner bottom wall of the storage compartment 3 is fixed with a slide block 11 that is slidably connected to the movable box 10. The left side of the dust collection box 4 is fixed with an exhaust fan 12. The front of the dust collection box 4 is hinged with a movable door 13. The front of the dust collection box 4 is provided with a limiting component 14 that is inserted into the movable door 13. A linkage frame 15 is fixed on the limiting component 14.

[0034] It should be noted that the cyclone separator 9 and dust collection box 4 enable the device to filter dust particles of different sizes in the gas, thereby improving the dust removal effect of the device. The limit component 14 limits the movable door 13, thereby controlling the movable door 13 and improving the ease of use of the device.

[0035] Please see Figure 2 To improve the dust removal effect, the dust collection box 4 in this embodiment includes a box body 401, a collection shell 402, a cleaning mechanism, a bag body 406, a pulse generator 407, and a shower pipe 408. The box body 401 is fixed to the top of the bottom plate 1, the collection shell 402 is fixed to the bottom of the box body 401, the cleaning mechanism is fixed to the collection shell 402, the bag body 406 is fixed between the front and rear inner side walls of the box body 401, the pulse generator 407 is fixed to the right side of the box body 401, and the shower pipe 408 is fixed to the inner wall of the left side of the box body 401. The right side of the shower pipe 408 passes through the box body 401 and communicates with the pulse generator 407.

[0036] It should also be noted that the installation of the pulse generator 407 and the shower pipe 408 facilitates the cleaning of the bag 406, thereby improving the dust removal effect of the dust collector 4. The installation of the cleaning mechanism also helps to improve the cleanliness of the box 401, thus improving the dust removal effect of the device.

[0037] It can be observed that the cleaning mechanism includes a servo motor 403, a rotating disk 404, and a scraper 405. The servo motor 403 is fixed to the inner walls of the front and rear sides of the collection shell 402. The rotating disk 404 is fixed to the output shaft of the servo motor 403. The rotating disk 404 is rotatably connected to the inner wall of the box 401. A rotation port is provided on the inner wall of the box 401. The rotating disk 404 is rotatably connected to the box 401 through the rotation port. The scraper 405 is fixed to the top of the rotating disk 404.

[0038] In this embodiment, the servo motor 403 powers the scraper 405 to rotate, thereby scraping the inner wall of the housing 401 to clean the dust adhering to the inside of the housing 401, which helps to improve the stability of the device.

[0039] Please see Figure 3 To improve gas stability, the cooling tower 8 in this embodiment includes an outer shell 801, a connecting box 802, a cooling box 803, and a drive pump 804. The outer shell 801 is fixed to the outside of the pipeline 5, and the connecting box 802 is fixed to the inner walls of the left and right sides of the outer shell 801. The cooling box 803 is fixedly connected to one side of the two connecting boxes 802. The cooling box 803 has a cylindrical structure and is inserted into the pipeline 5. A cooling block is fixed to the front of the left connecting box 802, and the drive pump 804 is fixed to the front of the right connecting box 802. The left and right sides of the drive pump 804 are respectively connected to the left and right connecting boxes 802.

[0040] In this embodiment, the cooling block helps ensure the cooling effect of the cooling box 803 on the gas. The connection between the cooling box 803 and the pipeline 5 enables the gas to contact the inner wall of the cooling box 803, thereby achieving gas cooling. The drive pump 804 facilitates the flow of coolant in the connecting box 802 and the cooling box 803, which in turn helps to cool the gas and improves the stability of the device.

[0041] Please see Figure 4 To improve the ease of use of the device, the limiting component 14 in this embodiment includes a fixed shell 1401, a sliding block 1402, a spring 1403, a displacement plate 1404, a movable disk 1405, and a limiting disk 1406. The fixed shell 1401 is fixed to the front of the dust collection box 4, and the sliding block 1402 is slidably connected to the top of the fixed shell 1401. A sliding opening is provided on the top of the fixed shell 1401, and the sliding block 1402 is slidably connected to the fixed shell 1401 through the sliding opening.

[0042] It can also be seen that the setting of the sliding port is conducive to the stable sliding of the sliding block 1402, which is conducive to the stable operation of the limit component 14, and thus conducive to improving the overall stability of the device.

[0043] It is easy to see that the sliding block 1402 is inserted into the right side of the movable door 13, and a spring 1403 is fixed on the front of the sliding block 1402. The spring 1403 is fixed to the front of the sliding block 1402, and a displacement plate 1404 that fits against the inner wall of the front of the fixed shell 1401 is fixed on the front of the spring 1403.

[0044] It is not difficult to see that the setting of spring 1403 helps to support the displacement plate 1404, thereby facilitating the stable locking of the fixed shell 1401 onto the limiting plate 1406, preventing the sliding block 1402 from disengaging, thus improving the stability of the movable door 13, and consequently improving the stability of the device in use.

[0045] It should be noted that the movable plate 1405 is fixed to the front of the displacement plate 1404, the limiting plate 1406 is fixed to the front of the movable plate 1405, the front of the limiting plate 1406 is fixed to the linkage frame 15, and the front of the fixed shell 1401 is provided with a limiting hole. The upper and lower sides of the limiting hole are adapted to the size of the limiting plate 1406, and the middle part of the limiting hole is adapted to the size of the movable plate 1405.

[0046] In this embodiment, the setting of the limiting hole facilitates the positioning of the limiting disk 1406 by using different hole diameters, which in turn facilitates the positioning of the sliding block 1402 and improves the stability of the device.

[0047] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0048] The working principle of the above embodiments is as follows:

[0049] The exhaust gas is introduced into the preheating chamber 2 through pipeline 5. The airflow speed is regulated and controlled by solenoid valve 6. Heating elements in the preheating chamber 2 raise the internal temperature of the exhaust gas. A catalyst is filled in the reaction tower 7 to promote the conversion of Sox and NOx into H2O and N2. Simultaneously, as the gas flows into the cooling tower 8, the drive pump 804 drives the water flow in the two connecting boxes 802, thereby improving the cooling effect of the cooling box 803 on the flowing gas, ensuring that the exhaust gas remains within a safe temperature range. Larger dust particles are then intercepted by the cyclone separator 9 and collected by the movable box 10. Smaller dust particles are then captured by the bag 406, improving the dust removal efficiency of the gas. The process is further enhanced by activating the servo motor. The machine 403 drives the scraper 405 to rotate, thereby scraping the inner wall of the housing 401 to clean the dust on the inner wall of the housing 401, improving the stability of the device. Then, the pulse generator 407 supplies power to make the shower pipe 408 blow air downwards, thereby expelling the dust in the bag 406. Finally, the clean gas is carried out of the device by the exhaust fan 12, realizing the dust removal and waste discharge of the gas. At the same time, by pressing the linkage frame 15, it slides downwards, thereby causing the limit plate 1406 to move, thereby disengaging the sliding block 1402 from the movable door 13, thereby opening the movable door 13, thereby enabling the internal maintenance of the dust collection box 4, improving the stability of the device. The overall device is convenient to use and has good performance.
