Description

Technical Field

[0001] The present invention relates to the technical field of flue gas purification, and in particular to a flue gas purification device and method for environmental protection. Background Art

[0002] During the power generation process, coal-fired power plants emit flue gas containing large amounts of harmful gases and particulate matter such as dust, nitrogen oxides, and sulfur dioxide. If thermal power emissions are not controlled, large amounts of sulfur dioxide, nitrogen oxides, and solid floating particles will be released into the atmosphere, which will not only endanger human health but also make it impossible to achieve sustainable development of the environment and ecology. In order to protect the environment, maintain ecological balance, and human health, the flue gas emissions from coal-fired power plants must be strictly purified.

[0003] However, during use, the existing flue gas purification treatment device relies solely on a water pump to extract chlorine water and directly inject it into the flue gas purification treatment device to contact the flue gas, resulting in poor reaction efficiency between the chlorine water and the flue gas. At the same time, the ammonium sulfate solution produced by the reaction of the flue gas and the chlorine water has an excessively high ammonium sulfate content, which makes it easy for ammonium sulfate crystals to form at the location of the drainage hole. As a result, the ammonium sulfate solution produced by the reaction of the chlorine water and the flue gas is difficult to discharge, affecting its use. Summary of the Invention

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0034] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale.

[0035] Example 1 Reference Figures 1 to 10 , which is the first embodiment of the present invention, provides a purification method for a flue gas purification device for environmental protection, thereby improving the flue gas treatment effect and avoiding blockage caused by ammonium sulfate crystallization.

[0036] The smoke is discharged into the filter mechanism 100 for filtration, thereby ensuring that the particles and impurities in the smoke are filtered, so that the exhaust gas particles are greatly reduced; The pressurized spray mechanism 200 is simultaneously used to block the filter mechanism 100, thereby increasing the pressure inside the filter mechanism 100 and assisting in spraying chlorine water mist to desulfurize the flue gas. This allows for more complete contact between the chlorine water mist and the flue gas under high pressure. The high pressure can also break through the reaction equilibrium limit under normal pressure, pushing the absorption reaction of sulfur dioxide and ammonia water toward the product, reducing the emission of unreacted sulfur dioxide, and improving the reaction efficiency. During the use of the pressurized spray mechanism 200, the anti-blocking mechanism 300 will also be driven to crush the ammonium sulfate crystals existing at the discharge, thereby preventing blockage and avoiding the situation where ammonium sulfate in the high-concentration ammonium sulfate solution crystallizes and blocks the discharge, causing blockage and affecting the discharge of the ammonium sulfate solution after the reaction.

[0037] Example 2 Reference Figures 1 to 4 , 8, and 9 are the second embodiment of the present invention, which provide a filtering mechanism 100 and a pressurized spray mechanism 200 to achieve pressurized desulfurization while filtering the flue gas.

[0038] The filtering mechanism 100 includes a purification pipe 101. The top of the purification pipe 101 is connected to the smoke exhaust. The bottom of the purification pipe 101 is provided with an exhaust hole 102. The exhaust holes 102 are provided with a plurality of holes 102 and are distributed in a circular shape at equal distances. Two purification filter plates 103 are provided inside the purification pipe 101. The surfaces of the purification filter plates 103 are fixedly connected to the inner wall of the purification pipe 101.

[0039] The pressurized spray mechanism 200 includes a sealing column 201, which is embedded in the exhaust hole 102. A connecting plate 202 is provided at the bottom of the purification tube 101. The top of the connecting plate 202 is fixedly connected to the bottom of the sealing column 201. A tension spring 203 is fixedly connected to the top of the connecting plate 202. There are several tension springs 203 and they are distributed in an annular shape at equal distances. The other end of the tension spring 203 is fixedly connected to the bottom of the purification tube 101. A chlorine water tank 204 is fixedly connected to the top of the purification tube 101. The chlorine water tank 204 is connected to the external chlorine water source. The outside of the bottom of the chlorine water tank 204 is connected to Atomizing nozzle 205, atomizing nozzle 205 passes through the interior of purification pipe 101, the interior of chlorine water tank 204 is movably connected to piston 206, a transmission member 207 is provided at the top of purification pipe 101, the three ends of the top of transmission member 207 are all passed through the interior of chlorine water tank 204 and fixedly connected to the bottom of piston 206, the bottom of transmission member 207 is movably connected to transmission rod 208, drainage grooves 209 are provided at the top and bottom of both sides of purification pipe 101, a stirring assembly 210 is fixedly connected to the bottom of connecting plate 202, and a cleaning assembly 211 is movably connected to the left side of the top of purification filter plate 103.

[0040] The stirring assembly 210 includes a motor 210a, the top of the motor 210a is fixedly connected to the bottom of the connecting plate 202, the output end of the motor 210a passes through the top of the connecting plate 202 and is fixedly connected to the bottom of the transmission rod 208, and a stirring blade 210b is provided on the top of the purification filter plate 103, and the stirring blade 210b is sleeved on the surface of the transmission rod 208.

[0041] The cleaning assembly 211 includes a brush strip 211a, which is located on the left side of the top of the purification filter plate 103. The right side of the brush strip 211a is fixedly connected to a movable sleeve 211b, which is sleeved on the surface of the transmission rod 208. Guide grooves 211c are provided at the top and bottom of both sides of the transmission rod 208. Sliders 211d are fixedly connected on both sides of the inner wall of the movable sleeve 211b. The surface of the slider 211d is slidably connected to the inner wall of the guide groove 211c. The top of the slider 211d is fixedly connected to a first spring 211e, and the other end of the first spring 211e is fixedly connected to the top of the inner wall of the guide groove 211c. The inner side of the drainage trough 209 is inlaid with a filter plate 211f, and the left side of the top of the brush strip 211a is fixedly connected to a scraper strip 211g.

[0042] Specifically, the flue gas is discharged into the purification pipe 101 and filtered through the purification filter plate 103, so that the particulate matter in the gas is greatly reduced.

[0043] Specifically, when the flue gas enters the purification pipe 101, the pressure in the purification pipe 101 will gradually increase, and in the process of increasing the pressure in the purification pipe 101, the sealing column 201 will continue to be pushed to drive the connecting plate 202 to move downward, so that the chlorine water is sprayed in the form of mist inside the purification pipe 101. Under the combined action of high pressure and misted chlorine water, the flue gas in the purification pipe 101 is more fully in contact with the chlorine water mist, and the high pressure can break through the reaction equilibrium limit under normal pressure, promote the absorption reaction of sulfur dioxide and ammonia water to proceed in the direction of the product, reduce the emission of unreacted sulfur dioxide, and improve the reaction efficiency.

[0044] Specifically, the starting motor 210a drives the stirring blade 210b to mix the flue gas and the atomized chlorine water in the purification tube 101, so as to make the reaction between the flue gas and the chlorine water more complete.

[0045] Specifically, during the rotation of the transmission rod 208, the brush bar 211a is driven to continuously gather the particles blocked on the purification filter plate 103 to one side, thereby ensuring the filtration efficiency of the purification filter plate 103, and in the process of cleaning the particles, the filter plate 211f is used to prevent the cleaned particles from entering the drainage trough 209. At the same time, during the rotation of the brush bar 211a, the scraper bar 211g is also driven to assist in cleaning the inner side of the filter plate 211f.

[0046] Furthermore, when the flue gas needs to be purified, the flue gas is discharged into the purification pipe 101, and then the flue gas enters the purification pipe 101, and then the flue gas is filtered through the purification filter plate 103, so that the particulate matter in the flue gas is filtered, ensuring that the particulate matter in the gas is greatly reduced when the gas is discharged through the exhaust hole 102.

[0047] Furthermore, the exhaust hole 102 is sealed by the sealing column 201 during use, thereby ensuring that the pressure in the purification pipe 101 will gradually increase during the process of the flue gas entering the purification pipe 101, and the sealing column 201 will continue to push the connecting plate 202 to move downward during the process of the pressure increase in the purification pipe 101. At this time, the tension spring 203 will continue to be pulled and generate tension, and in the process of the connecting plate 202 continuing to move downward, the connecting plate 202 will also drive the transmission rod 208 and the transmission member 207 to move downward, and then the transmission member 207 will pull the corresponding piston 206 to move downward, so that the piston 206 squeezes the chlorine water in the chlorine water tank 204 downward and sprays it out through the atomizing nozzle 205, so that the chlorine water is sprayed inside the purification pipe 101 in the form of mist, so that the purification Under the combined action of high pressure and misted chlorine water, the flue gas in the tube 101 is in more complete contact with the chlorine water mist, and the high pressure can break through the reaction equilibrium limit under normal pressure, promote the absorption reaction of sulfur dioxide and ammonia water towards the product direction, reduce the emission of unreacted sulfur dioxide, and improve the reaction efficiency. When flue gas is gradually added to the purification tube 101, the pressure is too high, causing the sealing column 201 to separate from the exhaust hole 102, and the high-pressure gas processed in the lower half of the purification tube 101 will quickly escape through the exhaust hole 102, causing the pressure in the purification tube 101 to drop rapidly. Then, the tension of the tension spring 203 can pull the connecting plate 202 to drive the sealing column 201 to quickly insert into the exhaust hole 102 for sealing, so that the pressure inside the purification tube 101 continues to increase, and this cycle repeats.

[0048] Furthermore, during the use of the purification tube 101, by starting the motor 210a, the motor 210a drives the transmission rod 208 movably connected to the transmission member 207 above to rotate, so that the transmission rod 208 drives the stirring blade 210b to rotate, and then the stirring blade 210b can mix the flue gas and the atomized chlorine water in the purification tube 101, thereby making the reaction between the flue gas and the chlorine water more complete.

[0049] Furthermore, during the rotation of the transmission rod 208, the transmission rod 208 will also drive the movable sleeve 211b to rotate through the slider 211d, so that the movable sleeve 211b drives the brush strip 211a to rotate along the top of the purification filter plate 103, thereby continuously gathering the particles blocked on the purification filter plate 103 to one side, ensuring the filtration efficiency of the purification filter plate 103, and using the filter plate 211f in the process of cleaning the particles can prevent the cleaned particles from entering the drain tank 209, and at the same time During the rotation of the brush strip 211a, the scraper strip 211g is also driven to assist in cleaning the inner side of the filter plate 211f. When the transmission rod 208 moves downward due to the high pressure inside the purification tube 101, the guide groove 211c and the slider 211d are used to slide together, so that when the transmission rod 208 moves downward, the brush strip 211a can still stay in its original position, and the elastic force of the first spring 211e can be used to ensure that the brush strip 211a is more closely attached to the top of the purification filter plate 103.

[0050] It should be noted that the storage tank is connected to the external chlorine water source through a one-way valve, so as to ensure that when the chlorine water mist is sprayed, the chlorine water will not flow back to the chlorine water source.

[0051] Example 3 Reference Figures 2 to 10 , which is the third embodiment of the present invention, provides an anti-blocking mechanism 300 to crush ammonium sulfate crystals to avoid blockage and inhibit the formation of ammonium sulfate crystals.

[0052] The anti-blocking mechanism 300 includes two metal parts 301. The inner side of the metal parts 301 is fixedly connected to the bottom of both sides of the transmission rod 208. The outer side of the metal parts 301 is magnetically adsorbed with a rubidium magnet 302. A first movable groove 303 is provided on the inner side of the top of the inner wall of the drainage groove 209. The inner wall of the first movable groove 303 is slidably connected to the surface of the rubidium magnet 302. A crushing sleeve 304 is provided on the top of the inner wall of the drainage groove 209. The bottom of the rubidium magnet 302 is fixedly connected to the inner side of the top of the crushing sleeve 304. An anti-crystallization component 305 is provided on the top of the inner wall of the drainage groove 209.

[0053] The anti-crystallization component 305 includes a second movable groove 305a, which is opened at the top of the inner wall of the drainage groove 209. The second movable groove 305a is slidably connected to the inside of the guide tube 305b, and a sealing plug 305c is provided inside the guide tube 305b. The top of the sealing plug 305c is fixedly connected to the top of the inner wall of the second movable groove 305a, and two rubber sealing rings 305d are fixedly connected to the bottom of the inner wall surface of the guide tube 305b. Storage boxes 305e are provided on both sides of the front of the purification tube 101 and the top of both sides of the front. Dispersant is stored in the storage box 305e, and the storage box 305e is connected to the guide tube 305b. The bottom of the guide tube 305b is fixedly connected to the top of the crushing sleeve 304. The guide tube 305b is connected to the crushing sleeve 304, and the bottom of the crushing sleeve 304 is movably connected to the mesh plate 305f.

[0054] Specifically, when the transmission member 207 moves downward, the crushing sleeve 304 is driven to move downward, so that the crushing sleeve 304 crushes the ammonium sulfate crystals accumulated below the inner wall of the drainage trough 209, so that the subsequent ammonium sulfate solution can dissolve and discharge the crushed ammonium sulfate when it is discharged through the drainage trough 209, thereby avoiding the formation of ammonium sulfate crystals in the drainage trough 209 and causing the drainage trough 209 to be blocked.

[0055] Specifically, during the downward movement of the crushing sleeve 304, part of the dispersant will be released and fall on the surface of the ammonium sulfate crystals at the bottom of the inner wall of the drainage trough 209. At the same time, the crushing sleeve 304 will compress the ammonium sulfate crystals, so that the contact between the dispersant and the ammonium sulfate crystals is more sufficient. The dispersant inhibits the crystallization of ammonium sulfate through multiple mechanisms such as physical adsorption, steric hindrance, dispersion stability, and complexation of impurity ions.

[0056] Furthermore, during the downward movement of the transmission member 207, the transmission member 207 will drive the corresponding metal member 301 to move downward, and use the magnetism of the rubidium magnet 302 to absorb the metal member 301 through the barrier between the first movable groove 303 and the inner wall of the purification tube 101, so that the metal member 301 can drive the rubidium magnet 302 to move downward when moving downward, and then the rubidium magnet 302 will drive the crushing sleeve 304 below to move downward, so that the crushing sleeve 304 can crush the ammonium sulfate crystals accumulated below the inner wall of the drainage trough 209, so that the subsequent ammonium sulfate solution can dissolve and discharge the crushed ammonium sulfate when it is discharged through the drainage trough 209, thereby avoiding the formation of ammonium sulfate crystals in the drainage trough 209 and causing the drainage trough 209 to be blocked.

[0057] Furthermore, during the downward movement of the crushing sleeve 304, the crushing sleeve 304 will also drive the guide tube 305b to move along the inner wall of the second movable groove 305a. Since the top of the sealing plug 305c is fixed to the top of the inner wall of the second movable groove 305a, the downward movement of the guide tube 305b will drive the two rubber sealing rings 305d to separate from the sealing plug 305c. At this time, the dispersant in the storage box 305e can enter the interior of the crushing sleeve 304 through the guide tube 305b and fall down to the bottom of the inner wall of the drainage groove 209 through the mesh on the mesh plate 305f. The surface of the ammonium sulfate crystals is compressed by the crushing sleeve 304, so that the contact between the dispersant and the ammonium sulfate crystals is more sufficient. The dispersant inhibits the crystallization of ammonium sulfate through multiple mechanisms such as physical adsorption, steric hindrance, dispersion stability, and complexation of impurity ions. When the crushing sleeve 304 moves upward and resets, the crushing sleeve 304 will drive the guide tube 305b and the storage box 305e to move upward and reset, so that the bottom of the sealing plug 305c moves to the inner side of the two rubber sealing rings 305d, so that the guide tube 305b can be sealed again to avoid the use of too much dispersant.

[0058] It should be noted that the bottom of the inner wall of the storage box 305e is set at an angle, so as to ensure that the powdered dispersant inside the storage box 305e can smoothly enter the guide tube. At the same time, the inertia generated by the up and down movement of the storage box 305e can assist in the discharge of the powdered dispersant, and the dispersant uses sodium polyacrylate, so that it will not affect the chemical properties of ammonium sulfate when used in small amounts.

[0059] The remaining structures are the same as those of Example 2.

[0060] Example 4 Reference Figures 1 to 10 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: this embodiment provides a flue gas purification device and method for environmental protection.

[0061] When the flue gas needs to be purified, the flue gas is discharged into the purification pipe 101, and then the flue gas enters the purification pipe 101, and then the flue gas is filtered through the purification filter plate 103, so that the particulate matter in the flue gas is filtered, ensuring that the particulate matter in the gas is greatly reduced when the gas is discharged through the exhaust hole 102.

[0062] During use, the exhaust hole 102 is sealed by the sealing column 201, so as to ensure that the pressure in the purification pipe 101 will gradually increase during the process of the flue gas entering the purification pipe 101, and the sealing column 201 will continue to push the connecting plate 202 to move downward during the process of the pressure increase in the purification pipe 101. At this time, the tension spring 203 will be continuously pulled and generate tension, and during the process of the connecting plate 202 continuing to move downward, the connecting plate 202 will also drive the transmission rod 208 and the transmission member 207 to move downward, and then the transmission member 207 will pull the corresponding piston 206 to move downward, so that the piston 206 squeezes the chlorine water in the chlorine water tank 204 downward and sprays it out through the atomizing nozzle 205, so that the chlorine water is sprayed inside the purification pipe 101 in the form of mist, so that the purification pipe 1 Under the combined action of high pressure and misted chlorine water, the flue gas in 01 is in more complete contact with the chlorine water mist, and the high pressure can break through the reaction equilibrium limit under normal pressure, promote the absorption reaction of sulfur dioxide and ammonia water towards the product direction, reduce the emission of unreacted sulfur dioxide, and improve the reaction efficiency. When flue gas is gradually added to the purification pipe 101, the pressure is too high, causing the sealing column 201 to separate from the exhaust hole 102, and the high-pressure gas processed in the lower half of the purification pipe 101 will quickly escape through the exhaust hole 102, causing the pressure in the purification pipe 101 to drop rapidly. Then, the tension of the tension spring 203 can pull the connecting plate 202 to drive the sealing column 201 to quickly insert into the exhaust hole 102 for sealing, so that the pressure inside the purification pipe 101 continues to increase, and this cycle repeats.

[0063] During the use of the purification tube 101, by starting the motor 210a, the motor 210a drives the transmission rod 208 movably connected to the transmission member 207 above to rotate, so that the transmission rod 208 drives the stirring blade 210b to rotate. Then the stirring blade 210b can mix the flue gas and the atomized chlorine water in the purification tube 101, thereby making the reaction between the flue gas and the chlorine water more complete.

[0064] During the rotation of the transmission rod 208, the transmission rod 208 also drives the movable sleeve 211b to rotate through the slider 211d, so that the movable sleeve 211b drives the brush strip 211a to rotate along the top of the purification filter plate 103, thereby continuously gathering the particles blocked on the purification filter plate 103 to one side, ensuring the filtration efficiency of the purification filter plate 103, and using the filter plate 211f in the process of cleaning the particles can prevent the cleaned particles from entering the drain tank 209, and at the same time During the rotation of the brush strip 211a, it will also drive the scraper strip 211g to assist in cleaning the inner side of the filter plate 211f. When the transmission rod 208 moves downward due to excessive pressure inside the purification tube 101, the guide groove 211c and the slider 211d slide together so that when the transmission rod 208 moves downward, the brush strip 211a can still stay in its original position. The elastic force of the first spring 211e can ensure that the brush strip 211a is more closely attached to the top of the purification filter plate 103.

[0065] When the connecting plate 202 moves up and down under the influence of pressure, the limiting rod 212 slides with the purification tube 101 to limit the connecting plate 202 in the front, back, left and right directions, ensuring that the movement of the connecting plate 202 is more stable. The limiting plate 213 can prevent the limiting rod 212 from being separated from the purification tube 101.

[0066] During the downward movement of the transmission member 207, the transmission member 207 will drive the corresponding metal member 301 to move downward, and use the magnetism of the rubidium magnet 302 to absorb the metal member 301 through the barrier between the first movable groove 303 and the inner wall of the purification tube 101, so that the metal member 301 can drive the rubidium magnet 302 to move downward when moving downward, and then the rubidium magnet 302 will drive the crushing sleeve 304 below to move downward, so that the crushing sleeve 304 can crush the ammonium sulfate crystals accumulated below the inner wall of the drainage trough 209, so that the subsequent ammonium sulfate solution can dissolve and discharge the crushed ammonium sulfate when it is discharged through the drainage trough 209, thereby avoiding the formation of ammonium sulfate crystals in the drainage trough 209 and causing the drainage trough 209 to be blocked.

[0067] During the downward movement of the crushing sleeve 304, the crushing sleeve 304 also drives the guide tube 305b to move along the inner wall of the second movable groove 305a. Since the top of the sealing plug 305c is fixed to the top of the inner wall of the second movable groove 305a, the guide tube 305b will drive the two rubber sealing rings 305d to separate from the sealing plug 305c when it moves downward. At this time, the dispersant in the storage box 305e can enter the interior of the crushing sleeve 304 through the guide tube 305b, and fall into the sulfur at the bottom of the inner wall of the drainage groove 209 through the mesh on the mesh plate 305f. The surface of the ammonium sulfate crystals is compressed by the crushing sleeve 304, so that the contact between the dispersant and the ammonium sulfate crystals is more sufficient, and the dispersant inhibits the ammonium sulfate crystals through multiple mechanisms such as physical adsorption, steric hindrance, dispersion stability, and complexation of impurity ions. When the crushing sleeve 304 moves upward and resets, the crushing sleeve 304 will drive the guide tube 305b and the storage box 305e to move upward and reset, so that the bottom of the sealing plug 305c moves to the inner side of the two rubber sealing rings 305d, so that the guide tube 305b can be sealed again to avoid using too much dispersant.

[0068] When the crushing sleeve 304 is reset, the air pressure is released too much at once and the connecting plate 202 is quickly pulled back to reset by the tension spring 203, thereby driving the crushing sleeve 304 to reset. As a result, the crushing sleeve 304 is reset too fast, causing the top of the crushing sleeve 304 to collide with the top of the inner wall of the drainage groove 209, thereby generating vibration. The vibration force is transmitted to the mesh plate 305f, causing the mesh plate 305f to drive the limiting member 305g to vibrate up and down along the inner wall of the limiting groove 305h. At the same time, the elastic force of the vibration spring 305i can help increase the vibration frequency of the screen plate 305f. When the screen plate 305f vibrates, the dispersant above the screen plate 305f, that is, the residual dispersant inside the crushing sleeve 304, will be vibrated, so that these residual dispersants can fall through the mesh holes on the screen plate 305f and fall on the bottom of the inner wall of the drainage trough 209, so as to reduce the influence of these dispersants on the subsequent ammonium sulfate solution when flowing through the drainage trough 209, thereby reducing the crystallization rate of ammonium sulfate.

[0069] When the storage box 305e is driven by the crushing sleeve 304 to move up and down, the storage box 305e will simultaneously drive the anti-separation block 307 to slide along the inner wall of the anti-separation groove 306, so as to limit the storage box 305e in the front, back, left and right directions during the movement, thereby ensuring the stability of the storage box 305e during the movement.

[0070] While the storage box 305e is moving up and down, the upper storage box 305e will drive the lower storage box 305e through the connecting rod 308 to drive the lower crushing sleeve 304, so that the upper crushing sleeve 304 is driven and the lower crushing sleeve 304 is driven to move synchronously. At the same time, the second spring 309 will be squeezed to generate a rebound force to facilitate the subsequent reset of the storage box 305e.

[0071] In summary, the flue gas to be treated is first discharged into the filter mechanism 100, and the particulate matter in the flue gas is filtered by the filter mechanism 100. Then, the pressurized spray mechanism 200 is used to allow the flue gas to fully contact with the atomized chlorine water under high pressure, thereby improving the reaction efficiency. The anti-blocking mechanism 300 is used to avoid blockage of the drainage caused by ammonium sulfate crystallization.
