[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] It should be noted that the above-mentioned ion solution regeneration device 6 is a conventional heating regeneration equipment. This structure is mainly used to heat the ion solution to achieve the regeneration of the ion solution. It has been widely used in the prior art. In the present invention, it is only used to realize the regeneration processing function of the ion solution in the desulfurization structure 7, and its internal structure, operating principle, wiring, and control method are no longer described in detail.

[0022] Further, in order to achieve the treatment of dust particles in the flue gas, refer to Figure 3The smoke separation structure 3 includes a dust collecting component 33 fixedly connected to the upper end of the horizontal part of the L-shaped processing tank 2. The dust collecting component 33 is connected to the desulfurization structure 7 through a guide pipe. The front part of the inner cavity of the L-shaped processing tank 2 located below the filter 31 is fixedly connected to the filter 31. The front end of the filter 31 is symmetrically fixedly connected to the rack 38. The outer surfaces of the two racks 38 are slidably connected to the front end of the filter 31 with a cleaning component 32.

[0023] When the smoke passes through the filter 31, the dust particles contained therein will be blocked by the filter 31, thereby separating the dust in the smoke and reducing the dust particle content in the smoke.

[0024] During the operation of this embodiment, the dust in the flue gas is separated by the action of the filter 31, and its surface is cleaned by the cooperation of the cleaning component 32 and the rack 38, so as to ensure the air intake efficiency of the filter 31 and improve the dust filtration efficiency; further, the flue gas is cooled by the action of the cooling structure 4 and the compounds that can react with water are preliminarily separated to reduce the impact on the rainwater environment after discharge; at the same time, the sulfide in the flue gas can be further separated by the action of the desulfurization structure 7, so as to reduce the sulfide content and reduce the impact on the environment.

[0025] Embodiment 2: Based on Embodiment 1, this embodiment drives the cable 1 36 and the cable 2 37 to wind or loosen on the surface of the winding shaft 35 through the action of the driving motor 34 and the winding shaft 35, drives the cleaning component 32 to slide on the surface of the filter 31 through the forward and reverse rotation of the driving motor 34 and the action of the cable 1 36 and the cable 2 37, and drives the cleaning roller brush 323 therein to sweep on the surface of the filter 31 through the cooperation of the cleaning component 32 and the rack 38, sweeping the dust on the surface into the sliding seat 321, and through the action of the dust exhaust component 1 324 in the sliding seat 321 and the dust exhaust component 2 325 on the upper part of the inner cavity of the L-shaped processing tank 2, the dust in the sliding seat 321 is sucked into the dust collecting component 33 through the action of the dust collecting component 33 and the desulfurization structure 7, thereby ensuring the ventilation efficiency of the filter 31; At the same time, the water pump 43 is used to drive the water to move upward and spray out from the distribution pipe 45, thereby cooling the flue gas passing through the two semi-permeable membranes 41. At the same time, harmful substances in the flue gas that can react with water will also react with the droplets in the water mist and separate from the flue gas, reducing the impact on water molecules in the atmospheric environment.

[0026] Specifically, in order to separate the dust in the flue gas, refer to Figure 3The smoke and dust separation structure 3 also includes a winding shaft 35 located at the lower part of the cleaning component 32, and the outer surface of the winding shaft 35 is symmetrically wound with cables 2 37, and the ends of the two cables 2 37 away from the winding shaft 35 are both bypassed from the inner surface of the L-shaped treatment tank 2 and fixedly connected to the upper end of the cleaning component 32, and the middle part of the outer surface of the winding shaft 35 is wound with a cable 1 36, and the end of the cable 1 36 away from the winding shaft 35 is fixedly connected to the lower end of the cleaning component 32, and the winding direction of the cable 1 36 and the cables 2 37 on both sides is opposite to that of the winding shaft 35.

[0027] The second cable 37 is pulled above the cleaning assembly 32. When the winding shaft 35 follows the driving motor 34 in the forward direction, the second cable 37 pulls the cleaning assembly 32 to move upward. At this time, the first cable 36 is relaxed, so that the surface of the filter screen 31 is cleaned through the cooperation of the cleaning assembly 32 and the rack 38. After the cleaning is completed, the dust is sent into the dust collecting assembly 33 through the cooperation of the cleaning assembly 32 and the dust collecting assembly 33. Cable 1 36 is pulled under the cleaning assembly 32. When the winding shaft 35 follows the reverse rotation of the driving motor 34, cable 1 36 will pull the cleaning assembly 32 down. At this time, cable 2 37 is stretched on the surface of the winding shaft 35, thereby driving the cleaning assembly 32 to reset.

[0028] Further, in order to clean the surface of the filter screen 31, refer to Figure 4 , Figure 5 and Figure 6 The cleaning assembly 32 includes a sliding seat 321 that is slidably connected to the front end of the filter screen 31. A cleaning roller brush 323 is symmetrically connected to the inner surface of the sliding seat 321. A scraper 322 is symmetrically fixedly connected to the rear of the inner surface of the sliding seat 321. The central axes of the two cleaning roller brushes 323 penetrate the inner cavity of the sliding seat 321 and extend to the connecting groove where the sliding seat 321 and the rack 38 are connected. Both sides of the outer surface of the upper cleaning roller brush 323 are fixedly connected to the row of teeth meshing with the rack 38 on the same side. Dust assembly 1 324, the outer surfaces of the two dust exhaust assemblies 324 are meshed with relay transmission shafts 327 rotatably connected to the inner wall of the connecting groove, the two relay transmission shafts 327 are connected to the cleaning roller brush 323 located at the lower part through belt drive, the dust exhaust assembly 1 324 is arranged on the top wall of the inner cavity of the sliding seat 321, and the position of the dust exhaust assembly 1 324 on the top wall of the inner cavity of the L-shaped processing tank 2 is provided with a slide groove 326 connected to the inner cavity of the dust collecting assembly 33, and the inner surface of the slide groove 326 is provided with a dust exhaust assembly 2 325.

[0029] The upper dust discharge assembly 324 meshes with the rack 38, driving the upper cleaning roller brush 323 to rotate, and the lower cleaning roller brush 323 and the upper cleaning roller brush 323 are driven to rotate in the opposite direction through the transmission cooperation between the lower relay transmission shaft 327 and the cleaning roller brush 323, thereby forming an inward cleaning effect; The scraper 322 is used to scrape off the dust on the surface of the cleaning roller brush 323 and temporarily store it inside the sliding seat 321 during the cleaning process.

[0030] The dust exhaust component 1 324 in the sliding seat 321 and the dust exhaust component 2 325 in the slide groove 326 cooperate with each other to send the dust into the dust collecting component 33 after the sliding seat 321 reaches the top of the inner cavity of the L-shaped processing tank 2 through the cooperation of the dust exhaust component 1 324 and the dust exhaust component 2 325.

[0031] Further, in order to discharge the dust in the sliding seat 321, refer to Figure 4 and Figure 7 The dust exhaust assembly 324 includes a T-shaped block 3241 slidably connected to the connecting groove at the upper part of the inner cavity of the sliding seat 321, a connecting groove 3243 connected to the left and right ends is opened at the lower end of the T-shaped block 3241, the left and right ends of the vertical part of the T-shaped block 3241 are fixedly connected to the limiting block 3242, and the lower end of the horizontal part of the T-shaped block 3241 is symmetrically fixedly connected to the compression spring 3244 fixedly connected to the upper end of the sliding seat 321; The dust exhaust component 325 includes two compression springs 3253 fixedly connected to the upper end of the L-shaped processing tank 2, and the upper ends of the two compression springs 3253 are fixedly connected to a T-block 3251, the outer surface of the vertical part of the T-block 3251 is slidably connected to the inner surface of the slide groove 326, and the lower end of the T-block 3251 is provided with a connecting groove 3252 connected to the left and right ends.

[0032] The slide groove 326 has the same shape as the dust exhaust component 1 324. When the sliding seat 321 rises under the action of the cable 2 37, the dust exhaust component 1 324 will enter the slide groove 326. At this time, the T-block 1 3241 will move downward under the action of the T-block 2 3251, and the compression spring 1 3244 will be compressed. At this time, the connecting groove 1 3243 is connected with the inner side of the sliding seat 321, and the upper side of the connecting groove 1 3243 is connected with the limit block 3242. The T-block 1 3241 continues to rise and pushes the T-block 2 3251 to move upward. At this time, the connecting groove 2 3252 is connected with the inner side of the dust collecting component 33, and the dust collecting component 33 is connected to the desulfurization structure 7 and will be sucked by the desulfurization structure 7. At this time, the negative pressure in the dust collecting component 33 will drive the air into the dust collecting component 33 through the sliding seat 321, the connecting groove 1 3243, and the connecting groove 2 3252, and carry the dust into the dust collecting component 33.

[0033] Further, in order to cool the flue gas and separate the harmful substances that can react with water, refer to Figure 8The cooling structure 4 includes a water collecting tank 42 opened in the inner cavity of the L-shaped treatment tank 2, a water pump 43 is fixedly connected to the bottom wall of the inner cavity of the water collecting tank 42, an output end of the water pump 43 is fixedly connected to a distribution pipe 45 fixedly connected to the top wall of the inner cavity of the L-shaped treatment tank 2 through a pipeline, a plurality of atomizing nozzles 46 connected to the inner cavity of the distribution pipe 45 are fixedly connected in a rectangular distribution at the lower part of the outer surface of the distribution pipe 45, a mesh plate 44 is fixedly connected to the upper part of the inner surface of the water collecting tank 42, and a semipermeable membrane 41 is fixedly connected to both the left and right ends of the mesh plate 44.

[0034] The water pump 43 delivers the water in the water collection tank 42 into the distribution pipe 45, and sprays it out through the atomizing nozzle 46 at the bottom of the distribution pipe 45, forming water mist between the two semi-permeable membranes 41, thereby allowing the flue gas to fully contact the droplets in the water mist and preliminarily cool the flue gas. At the same time, the harmful substances in it that can react with water will also be absorbed by the water and fall back into the water collection tank 42 at the bottom. Pipes for drainage and water replenishment are also set in the water collection tank 42, but this setting is common knowledge and will not be displayed or further elaborated in the present invention.

[0035] Embodiment 3: Based on Embodiment 4, this embodiment utilizes the function of the air pump 74 to extract the flue gas in the relay chamber 71 and send it into the aeration component 75. The flue gas after dust removal by the filter 31 is aerated into bubbles by the aeration component 75 and filled into the ion solution in the desulfurization chamber 73, thereby further separating harmful substances such as sulfides that cannot react with water, thereby reducing harm to the environment.

[0036] Specifically, to achieve flue gas desulfurization, refer to Fig. 9 The desulfurization structure 7 includes a relay chamber 71 whose vertical part is opened in a herringbone shape, an installation chamber 72 and a desulfurization chamber 73. An air pump 74 is fixedly connected to the bottom wall of the inner cavity of the installation chamber 72. The input end of the air pump 74 is connected to the inner cavity of the relay chamber 71. The output end of the relay chamber 71 is provided with an aeration component 75 located on the bottom wall of the inner cavity of the desulfurization chamber 73. The top of the inner cavity of the desulfurization chamber 73 is connected to the air outlet pipe 5. The relay chamber 71 is connected to the horizontal part of the inner cavity of the L-shaped treatment tank 2 through a connecting hole. The relay chamber 71 is connected to the drive motor 34 through a guide pipe. The desulfurization chamber 73 is connected to the ion solution regeneration device 6 through a circulation pipe.

[0037] The air pump 74 draws air from the relay chamber 71, thereby sending the flue gas treated by the smoke and dust separation structure 3 and the cooling structure 4 into the aeration component 75 through the connecting hole at the bottom of the relay chamber 71, and at the same time draws air from the drive motor 34 through the guide pipe to cooperate with the cleaning component 32 to exhaust dust.

[0038] Further, in order to break the flue gas into bubbles and fill them into the ion solution in the desulfurization chamber 73, refer to Fig.10The aeration assembly 75 includes a connecting pipe 751 fixedly connected to the output end of the air pump 74, the upper end of the connecting pipe 751 is rotatably connected to an aeration head 752, a plurality of shunt pipes 753 are fixedly connected to the outer surface of the aeration head 752 in an annular distribution, and a plurality of inclined aeration pipes 754 are linearly distributed and fixedly connected to the outer surfaces of the plurality of shunt pipes 753.

[0039] The connecting pipe 751 is connected to the output end of the air pump 74. The flue gas delivered by the air pump 74 will be ejected through the capillaries on the aeration head 752, thereby forming bubbles in the ion solution in the desulfurization chamber 73. At the same time, part of the air will also be ejected from the aeration pipe 754 through the diverter pipes 753 on both sides, forming thrust, thereby driving the diverter pipe 753 and the aeration head 752 to rotate, so that the bubbles do not move horizontally upward, but move in a bolt-like shape.

[0040] Further, to disturb the bubble group and improve its reaction efficiency, see Fig.11 The aeration assembly 75 also includes a one-way valve 755 arranged at the outlet of the inner surface of the connecting pipe 751, and a cross support frame 756 is fixedly connected to the outlet of the inner surface of the connecting pipe 751. The cross support frame 756 is fixedly connected to a turbulence fan 757 through a cable rotatably connected to its inner surface, and a plurality of interconnected turbulence holes 758 are opened on the surface of the blades of the turbulence fan 757.

[0041] Since the air outlet capacity of the aeration head 752 and the aeration pipe 754 is limited, the smoke is redundant and will come out from the tail end of the diversion pipe 753. During the rotation of the diversion pipe 753, the one-way valve 755 at the tail end of the diversion pipe 753 will guide the smoke to impact the rear spoiler fan 757. At the same time, due to the rotating cutting water flow, the spoiler fan 757 will rotate. At this time, the spoiler hole 758 will stir this part of the smoke to form finer bubbles. Bubbles can increase the contact area between flue gas and ion solution, thereby accelerating its desulfurization effect.

[0042] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
