Technical Field
[0001] The utility model relates to the technical field of flue gas treatment, in particular to a device for removing fine particles in wet flue gas desulfurization. Background Art
[0002] With the acceleration of industrialization, energy consumption continues to increase, especially in industries that use coal as the main energy source, such as thermal power generation and industrial boilers. A large amount of flue gas will be generated during the combustion process. These flue gases contain a variety of pollutants, among which fine particulate matter and sulfur dioxide are two types of pollutants that are most harmful to the environment and human health.
[0003] In traditional flue gas treatment technology, although there are some methods to purify flue gas, the effect of removing fine particles is not ideal. For example, some simple filtering devices have low interception efficiency for fine particles with smaller particle size, because fine particles have strong permeability and can easily pass through ordinary filter media. In addition, some traditional wet desulfurization equipment mainly focuses on the removal of sulfur dioxide and lacks targeted design for fine particle removal. During operation, these devices may find it difficult to effectively capture fine particles, resulting in fine particles being discharged into the atmosphere along with the treated flue gas.

The motor drives the screw to rotate, and then the brush plate moves back and forth on the surface of the electrostatic precipitator, so as to promptly remove the fine particles adsorbed on the electrostatic precipitator to prevent their accumulation from affecting the adsorption efficiency, thereby ensuring that the electrostatic precipitator continuously and efficiently removes fine particles. The collection box is used to collect the removed fine particles.

[0015] Through the above technical solution, the flue gas can smoothly enter the treatment box from the desulfurization tank, ensuring the normal operation of subsequent fine particle removal and flue gas purification.
[0016] The bottom end of the flow guide pipe is fixedly connected to the surface of the processing box.
[0017] Compared with the prior art, the beneficial effects of the present invention are:
[0018] The utility model utilizes the principle of electrostatic adsorption through the electrostatic precipitator, which can effectively adsorb fine particles in the flue gas and has a strong capture ability for fine particles, thereby ensuring the removal effect of fine particles. After the fan is started, the flue gas can be blown to the electrostatic precipitator on one side to ensure that the fine particles in the flue gas can be adsorbed by the electrostatic precipitator.

[0026] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment. Example
[0027] Please combine Figure 1-5A device for removing fine particles in wet flue gas desulfurization of this embodiment includes a workbench 1, a treatment box 2 is fixedly connected to the upper surface of the workbench 1, an electrostatic precipitator 3 is fixedly connected to the inner wall of the treatment box 2, a limiting slide groove 4 is provided on the inner top wall of the treatment box 2, a movable plate 5 is slidably connected inside the limiting slide groove 4, a brush plate 6 is fixedly connected to the surface of the movable plate 5, a mounting platform 7 is fixedly connected to the surface of the treatment box 2, a motor 8 is fixedly connected to the surface of the mounting platform 7, a screw rod 9 is fixedly connected to the surface of the motor 8, and the screw rod 9 passes through the movable plate 5, a collecting box 10 is arranged below the electrostatic precipitator 3, and the electrostatic precipitator 3 uses the principle of electrostatic adsorption to adsorb fine particles in the flue gas. The rotation of the motor 8 drives the screw rod 9 to rotate. Since the screw rod 9 passes through the movable plate 5 and the movable plate 5 is restricted in sliding in the limiting groove 4, the movable plate 5 will move along the limiting groove 4 when the screw rod 9 rotates, thereby driving the brush plate 6 to move back and forth on the surface of the electrostatic precipitator 3, removing the fine particles adsorbed on the electrostatic precipitator 3, and causing the fine particles to fall into the collection box 10 for unified collection.
[0028] A support column 11 is fixedly connected to the inner bottom wall of the processing box 2 , and a support plate 12 is fixedly connected to the top of the support column 11 .
[0029] An activated carbon filter 13 is arranged on the surface of the support plate 12, and the lower surface of the collecting box 10 is in contact with the support plate 12. After the fine particles in the flue gas are adsorbed by the electrostatic precipitator 3, the remaining flue gas is further filtered and purified by the activated carbon filter 13 arranged on the surface of the support plate 12. The activated carbon filter 13 relies on its own adsorption performance to adsorb impurities in the flue gas.
[0030] An exhaust pipe 14 is fixedly connected to the surface of the processing box 2, and a fan 15 is fixedly installed on the inner wall of the processing box 2 by bolts. The fan 15 blows the flue gas toward the electrostatic precipitator 3 to ensure that fine particles in the flue gas can be adsorbed by the electrostatic precipitator 3. The treated flue gas is discharged from the processing box 2 through the exhaust pipe 14.
[0031] A sealing door 16 is hinged on the surface of the processing box 2. The sealing door 16 is hinged on the surface of the processing box 2. When the fine particles in the collecting box 10 need to be processed, the sealing door 16 is opened to conveniently take out the collecting box 10.
[0032] A desulfurization tank 17 is fixedly connected to the upper surface of the workbench 1, and a guide pipe 18 is fixedly connected to the top of the desulfurization tank 17. The flue gas generated by the desulfurization tank 17 enters the interior of the processing box 2 through the guide pipe 18 at the top, providing a flue gas source for the entire fine particle removal and flue gas purification process.
[0033] The bottom end of the flow guide pipe 18 is fixedly connected to the surface of the processing box 2 .
[0034] The implementation principle of a device for removing fine particles in a flue gas wet desulfurization in an embodiment of the present application is: open the desulfurization tank 17 to make it start to generate flue gas, and the flue gas generated by the desulfurization tank 17 enters the interior of the treatment box 2 through the guide pipe 18, and then start the fan 15, the fan 15 blows the flue gas to the electrostatic precipitator 3, so that the fine particles in the flue gas can be adsorbed by the electrostatic precipitator 3, and start the motor 8, and the rotation of the motor 8 drives the screw 9 to rotate. Since the screw rod 9 passes through the movable plate 5 and the movable plate 5 is limited in sliding in the limiting slide groove 4, the movable plate 5 will move along the limiting slide groove 4 when the screw rod 9 rotates, thereby driving the brush plate 6 to move back and forth on the surface of the electrostatic precipitator 3. The electrostatic precipitator 3 uses the principle of electrostatic adsorption to adsorb fine particles in the flue gas. The adsorbed fine particles are removed by the back and forth movement of the brush plate 6 and fall into the collection box 10 for unified collection. After the fine particles in the flue gas are adsorbed by the electrostatic precipitator 3, the remaining flue gas is further filtered and purified by the activated carbon filter 13 arranged on the surface of the support plate 12. The activated carbon filter 13 relies on its own adsorption performance to adsorb impurities in the flue gas. The treated flue gas is discharged from the treatment box 2 through the exhaust pipe 14. When it is necessary to process the fine particles in the collection box 10, the sealing door 16 hinged on the surface of the treatment box 2 is opened, the collection box 10 is taken out, the fine particles collected therein are cleaned and then put back in place, and the sealing door 16 is closed.
[0035] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
