[0002] Boiler flue gas desulfurization and denitrification equipment refers to equipment used to treat sulfur dioxide and nitrogen oxides contained in flue gas generated by combustion processes such as coal-fired boilers and power plants. Desulfurization refers to the process of converting or absorbing and removing sulfur dioxide in flue gas, and denitrification refers to the process of converting or removing nitrogen oxides in flue gas. These equipment usually use chemical absorption, catalytic reduction, dry absorption and other methods to achieve the purpose of desulfurization and denitrification, so as to reduce the impact of flue gas on the environment and protect the quality of the atmospheric environment.

Obviously, the specific implementation described is only a part of the specific implementation of the utility model, not all of the specific implementation. Based on the specific implementation of the utility model, all other specific implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Reference Figure 1-5 , a specific implementation method provided by the utility model:

[0035] A boiler flue gas desulfurization and denitrification device, comprising a main body box 1, a fixing plate 15 is fixedly connected to the lower end of the outer wall of the main body box 1, a connecting plate 3 is fixedly connected to the upper parts of both sides of the outer wall of the main body box 1, a servo motor 5 is fixedly connected to the middle of one end of the outer wall of the connecting plate 3 close to the center of the main body box 1, a rotating fan 6 is fixedly connected to the output end of the servo motor 5, a copper plate 8 is fixedly connected to the upper parts of both sides of the inner wall of the main body box 1, a heat dissipation fin 7 is fixedly connected to the side of the outer wall of the copper plate 8 away from the center of the main body box 1, a filter frame 10 is slidably connected to the middle of the front end of the inner wall of the main body box 1, a water pump 9 is fixedly connected to the middle of the upper surface of the main body box 1, and a liquid tank 2 is fixedly connected to one side of the rear end of the upper surface of the main body box 1;

[0036] The internal copper plate 8 is installed on the upper part of both sides of the inner wall of the main box 1, and is responsible for absorbing and conducting the heat generated by the main box 1. In order to improve the heat dissipation efficiency, the outer wall of the copper plate 8 is connected with heat dissipation fins 7. These fins increase the heat dissipation area, thereby enhancing the exchange of heat with the ambient air. The servo motor 5 is started, and the motor will drive the rotating fan 6 to rotate when it starts. This active heat dissipation measure can accelerate the air flow and promote the rapid dissipation of heat. With the joint effect of this series of heat dissipation measures, the temperature in the main box 1 can be effectively reduced to an appropriate level, providing the necessary temperature conditions for the smooth progress of the chemical reaction.

[0037] An inlet valve 13 is connected to the upper part of one side of the outer wall of the liquid tank 2, and an outlet valve 14 is connected to the lower part of one side of the outer wall of the liquid tank 2. By arranging the inlet valve 13 and the outlet valve 14 at the upper and lower parts of the liquid tank 2, the water flow entering and discharging the liquid tank 2 can be accurately controlled to ensure the reasonable replenishment and replacement of the desulfurizer or the treatment liquid, and maintain the liquid level and concentration required for the chemical reaction. The outlet of the water pump 9 is connected to the inside of the main box 1 through a pipeline, and the outlet of the water pump 9 is connected to the inside of the main box 1 through a pipeline, which provides a continuous liquid supply for the desulfurization and denitrification reaction. The lower end of the main box 1 is connected to a leak plate 4, and the lower end of the leak plate 4 is connected to a connecting pipe 18. The leak plate 4 at the lower end of the main box 1 and the connecting pipe 18 are connected to make the devices fit more closely. The outer sleeve of the connecting pipe 18 is provided with an electromagnetic control valve 17, and an electromagnetic control valve 1 is arranged outside the connecting pipe 18. 7. It realizes precise control of flue gas or liquid discharge and can respond quickly according to the actual needs of the system. A sealing gasket 11 is fixedly connected to the edge of the front end of the outer wall of the filter frame 10. A filter screen 12 is arranged inside the filter frame 10. The sealing gasket 11 is installed at the edge of the front end of the outer wall of the filter frame 10 to prevent the leakage of flue gas or liquid at the connection between the filter frame 10 and the main box 1. When the filter screen 12 needs to be replaced or cleaned, the filter frame 10 slides and is easy to replace. The water suction port of the water pump 9 is connected to the inside of the liquid box 2 through a pipeline. The connection between the water suction port of the water pump 9 and the inside of the main box 1 ensures that the water pump 9 can stably extract the desulfurizer or the treated liquid. The four corners of the lower surface of the fixed plate 15 are fixedly connected with support plates 16. The support plate 16 on the lower surface of the fixed plate 15 not only enhances the stability of the equipment, but also provides structural support for the equipment, making the equipment more firm.

[0038] Working principle: The flue gas is guided through the filter 12 inside the filter frame 10. The filter 12 can capture and remove large particles of dust and impurities carried in the flue gas. This process not only protects the sensitive components inside the equipment from wear and blockage, but also the heat in the flue gas is effectively absorbed and conducted through the copper plates 8 installed on the upper parts of both sides of the inner wall of the main box 1. The excellent thermal conductivity of the copper plates 8 makes it an efficient medium for transferring heat from the flue gas to the external environment. In order to further improve the heat dissipation efficiency, the outer wall of the copper plates 8 is connected with heat dissipation fins 7. These fins significantly increase the heat dissipation area and improve the heat exchange efficiency with the ambient air, thereby accelerating the heat dissipation. The starting belt of the servo motor 5 The dynamic fan 6 rotates. This active heat dissipation measure further improves the heat dissipation efficiency by accelerating the air flow. This design helps the copper plate 8 and the heat dissipation fins 7 to dissipate heat more quickly, ensuring that the temperature in the main box 1 is effectively controlled and reduced to an appropriate level. At this appropriate temperature, the chemical reaction in the equipment can proceed smoothly. The water pump 9 is responsible for conveying the desulfurizer or the treatment liquid. The SO2 and NOx in the flue gas react chemically with these desulfurizers and denitrifiers. SO2 reacts with the alkaline solution to generate sulfate, while NOx is converted into nitrogen and water by the reducing agent. These chemical reactions effectively convert pollutants into harmless or easy-to-handle substances, thereby achieving flue gas purification.
