Description

Technical Field

[0001] This invention belongs to the field of flue gas desulfurization technology, specifically a flue gas dust removal and desulfurization device. Background Technology

[0002] Flue gas desulfurization (FGD) refers to the removal of sulfur oxides from flue gas or other industrial waste gas. Based on the type of desulfurizing agent, FGD technology can be divided into the following five methods: calcium method based on CaCO3, magnesium method based on MgO, sodium method based on Na2SO3, ammonia method based on NH3, and organic alkali method based on organic alkali.

[0003] A patent with publication number CN108686480A discloses a flue gas desulfurization and dust removal device, including a tank. The four corners of the lower surface of the tank are fixedly connected to the tops of four support legs. An air inlet pipe is snapped onto the left side of the tank, and the right end of the air inlet pipe is connected to the interior of the tank. The right side of the tank is fixedly connected to the left side of a circulating water pump via a connecting rod. The outlet of the circulating water pump is connected to one end of a second spray pipe via a second three-way pipe. The flue gas desulfurization and dust removal device of the present invention, by setting up a circulating water pump, a first spray pipe, a second spray pipe, a drain pipe, an inlet pipe, a filter pipe, and a connecting pipe, filters impurities in the liquid. The filtered liquid will not clog the circulating water pump and is then sent back to the first and second spray pipes for operation by the circulating water pump, which reduces the waste of desulfurization liquid and reduces costs.

[0004] In current technologies, sulfur gas is directly injected into the activated carbon during flue gas desulfurization. Due to the excessively fast flue gas transport speed, a large amount of flue gas is directly emitted, failing to effectively remove dust and sulfur.

[0005] Therefore, the present invention provides a flue gas dust removal and desulfurization device. Summary of the Invention

A sulfur gas conveying pipe is fixedly connected to the inner wall of the flue gas filter plate at the top edge of the desulfurization and dust removal tank.

A flue gas filter layer is fixedly connected to the outer surface of the flue gas filter plate.

[0008] Preferably, a sulfur gas conveying tank is fixedly installed on the top surface of the foundation plate and on the back of the desulfurization and dust removal tank, and the bottom end of the sulfur gas conveying pipe extends into the interior of the high-efficiency activated carbon.

[0009] Preferably, two sets of flue gas recovery tanks are provided on both sides of the sulfur gas conveying tank, and three sets of guide gas pipes are fixedly connected to the output ends of the sulfur gas conveying tank and the flue gas recovery tank respectively.

[0010] Preferably, one end of the guide gas pipe extends to the inner wall of the top of the sulfur gas conveying pipe, and one end of the other two sets of guide gas pipes extends to the inner wall of the top of the desulfurization and dust removal tank.

[0011] Preferably, anti-sway platforms are fixedly installed on the top surface of the foundation platform and at the two side edges, and the anti-sway platforms are located at the bottom edge of the pressure conveying tank.

[0012] Preferably, a support frame is fixedly installed on the top surface of the foundation platform, and the top surface of the hydraulic rod is fixedly installed on the bottom surface of the support frame.

[0013] Preferably, one end of the pressure relief pipe extending into the inside of the desulfurization and dust removal tank is located in the middle of the two sets of flue gas filter plates. A second sealing cover is fixedly installed on the top surface of the desulfurization and dust removal tank, and the outer surface of the second sealing cover is movably sleeved on the top outer surface of the sulfur gas conveying pipe.

[0014] Preferably, the surface of the flue gas filter layer is movably overlapped with the top surface of the high-efficiency activated carbon, and two sets of cooling boxes are fixedly installed on the top surface of the foundation plate, with the two sets of cooling boxes respectively located at the two side edges of the desulfurization and dust removal tank.

[0015] Preferably, water source guide pipes are fixedly installed on both sides of the cooling box, and a distribution guide pipe is fixedly installed on both sides of the cooling box. A sealing cover is movably fitted onto the top surface of the cooling box.

[0016] Preferably, one end of the differentiation guide pipe is connected to one end of the air guide pipe, and multiple sets of cooling pipes are fixedly installed on the outer surface of the differentiation guide pipe and on the inner wall of the cooling box, and the inner wall of the cooling box and on the outer surface of the cooling pipes are filled with condensate.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The flue gas dust removal and desulfurization device of the present invention is used in conjunction with a sulfur gas conveying pipe to transport high-temperature flue gas and directly inject the flue gas into the center of high-efficiency activated carbon. The high-efficiency activated carbon is used to perform all-round dust removal and desulfurization treatment on the flue gas. As the gas is continuously filled and accumulated, the hot flue gas will gradually begin to rise. At this time, it will come into contact with the flue gas filter plate that is in contact with the high-efficiency activated carbon, and the flue gas filter layer on the outer surface of the flue gas filter plate will be used to filter the rising flue gas and some impurity particles that have not been completely filtered and dust removed.

[0019] 2. In the flue gas dust removal and desulfurization device of the present invention, when the flue gas remains inside the high-efficiency activated carbon, the sealing extrusion plate is extended and retracted back and forth with the help of the hydraulic rod. At this time, when the sealing extrusion plate slides up and down on the inner wall of the suction and conveying tank, the desulfurized flue gas inside the desulfurization and dust removal tank and the high-efficiency activated carbon is extracted and pushed into the bottom cavity of the suction and conveying tank by the gas. When the gas circulates and flows rapidly inside the high-efficiency activated carbon, it will accelerate the rapid penetration of the flue gas inside the high-efficiency activated carbon, thereby increasing the contact range and contact area between the flue gas and the high-efficiency activated carbon, and increasing the flue gas desulfurization effect.

[0020] 3. In the flue gas dust removal and desulfurization device of the present invention, when the hydraulic rod presses down on the sealing extrusion plate, the flue gas inside the suction conveying tank is magnetically injected into the desulfurization and dust removal tank. The accumulation of flue gas will quickly move upward, and the flue gas will quickly pass through the flue gas filter layer. As the airflow quickly passes through the flue gas filter layer, the impurity particles inside the flue gas will remain on the surface of the flue gas filter layer. When the hydraulic rod pulls back on the sealing extrusion plate, under the reverse push of the flue gas, the flue gas filter layer will bulge downward. At this time, the dust and impurities left on the bottom surface of the flue gas filter layer will be guided in reverse by the gas to the interior of the high-efficiency activated carbon. By using the back-and-forth penetration of the gas, the dust particles inside the flue gas are filtered, removed, and peeled off.

[0021] 4. In the flue gas dust removal and desulfurization device of the present invention, when the flue gas moves back and forth inside the desulfurization and dust removal tank and the pressure conveying tank, the flue gas will pass through the cooling pipe through the decomposition guide pipe. Due to the large number of cooling pipes, the contact area and range with the condensate can be greatly increased. As a result, when the high-temperature flue gas passes through the cooling pipe, the condensate will quickly absorb heat and cool down the high temperature inside the flue gas. This prevents the high-temperature flue gas from causing the adsorbed molecules in the micropores of the activated carbon to desorb. At the same time, the pore size may become larger, thereby reducing the adsorption capacity and weakening the adsorption capacity of the activated carbon. At the same time, the water source guide pipe is used to quickly circulate the condensate inside the cooling tank and cool down the flowing condensate. Attached Figure Description

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figures 1 to 6 As shown, an embodiment of the flue gas dust removal and desulfurization device of the present invention includes a foundation plate 11 and a desulfurization and dust removal tank 14 fixedly installed at the center of the top of the foundation plate 11. Two sets of suction and conveying tanks 121 are detachably installed on the top surface of the foundation plate 11 and located at the two side edges. A hydraulic rod 112 is fixedly installed on the inner surface of the top of the suction and conveying tank 121. A sealing extrusion plate 113 is fixedly connected to the output end of the hydraulic rod 112, and the outer surface of the sealing extrusion plate 113 is movably sleeved on the inner wall of the suction and conveying tank 121. A gas guide pipe is fixedly installed at the bottom edge of the outer side of the suction and conveying tank 121. One end of the gas guide pipe is fixedly connected to the outer surface of the desulfurization and dust removal tank 14. Two sets of flue gas filter plates 144 are fixedly installed on the inner wall of the desulfurization and dust removal tank 14. High-efficiency activated carbon 146 is filled on the inner wall of the desulfurization and dust removal tank 144 at the bottom edge of the flue gas filter plate 144. A sulfur gas conveying pipe 142 is fixedly connected to the inner wall of the flue gas filter plate 144 at the top edge of the desulfurization and dust removal tank 14. A pressure relief pipe 141 is fixedly installed on the outer surface of the pressure pumping tank 121 and the desulfurization and dust removal tank 14 at the middle position. A flue gas filter layer 145 is fixedly connected to the outer surface of the flue gas filter plate 144.

[0033] The high-temperature flue gas is transported in conjunction with the sulfur gas conveying pipe 142 and directly injected into the center of the high-efficiency activated carbon 146. The high-efficiency activated carbon 146 is used to perform all-round dust removal and desulfurization treatment on the flue gas. As the gas is continuously filled and accumulated, the hot flue gas will gradually begin to rise. At this time, it will come into contact with the flue gas filter plate 144 that is attached to the high-efficiency activated carbon 146, and the flue gas filter layer 145 on the outer surface of the flue gas filter plate 144 will be used to filter the rising flue gas and some impurity particles that have not been completely filtered and dust removed.

[0034] When the flue gas remains inside the high-efficiency activated carbon 146, the sealing extrusion plate 113 is extended and retracted by the hydraulic rod 112. At this time, when the sealing extrusion plate 113 slides up and down on the inner wall of the suction and conveying tank 121, the desulfurized flue gas inside the desulfurization and dust removal tank 14 and the high-efficiency activated carbon 146 is extracted and pushed into the bottom cavity of the suction and conveying tank 121 by the gas. When the gas circulates and flows rapidly inside the high-efficiency activated carbon 146, it will accelerate the rapid penetration of the flue gas inside the high-efficiency activated carbon 146, thereby increasing the contact range and contact area between the flue gas and the high-efficiency activated carbon 146 and increasing the desulfurization effect of the flue gas.

[0035] When the sealing extrusion plate 113 presses down inside the pressure conveying tank 121, it will guide the flue gas inside the pressure conveying tank 121 back into the interior of the high-efficiency activated carbon 146, so that the flue gas and the high-efficiency activated carbon 146 will be repeatedly alternated, thereby achieving the effect of secondary desulfurization treatment of the flue gas.

[0036] When the hydraulic rod 112 presses down on the sealing extrusion plate 113, the flue gas inside the suction conveying tank 121 is magnetically injected into the desulfurization and dust removal tank 14. The accumulated flue gas will quickly move upward and cause the flue gas to pass through the flue gas filter layer 145 quickly. As the airflow passes through the flue gas filter layer 145 quickly, the impurity particles inside the flue gas will remain on the surface of the flue gas filter layer 145. When the hydraulic rod 112 pulls back on the sealing extrusion plate 113, under the reverse push of the flue gas, the flue gas filter layer 145 will bulge downward. At this time, the dust and impurities left on the bottom surface of the flue gas filter layer 145 will be guided by the gas to the interior of the high-efficiency activated carbon 146. By using the back and forth penetration of the gas, the dust particles inside the flue gas are filtered, removed, and peeled off.

[0037] When the flue gas passes through the flue gas filter layer 145, the pushing force of the flue gas will cause the flue gas filter layer 145 to be in an upward semi-circular bulge, so that the particles inside the flue gas are left inside the flue gas filter layer 145. Utilizing the curvature of the flue gas filter layer 145, the impurity particles will continue to transfer upward, so that the connection between the flue gas filter layer 145 and the flue gas filter plate 144 always maintains a ventilation state. When the flue gas is pushed in the opposite direction, the flue gas filter layer 145 will be in a downward bulge. At this time, the impurities accumulated in the center of the flue gas filter layer 145 will be loosened by the deformation of the flue gas filter layer 145. At this time, the loosened impurities are peeled off from the surface of the flue gas filter layer 145 under the push of the air source.

[0038] When the sealing extrusion plate 113 on one end of the hydraulic rod 112 moves back and forth inside the pressure conveying tank 121, the cavity between the top of the sealing extrusion plate 113 and the pressure conveying tank 121 will draw gas from the inside of the pressure relief pipe 141, thereby guiding the filtered gas inside the desulfurization and dust removal tank 14 into the inside of the pressure conveying tank 121. When extruding in the reverse direction, the extracted flue gas can be re-injected into the inside of the desulfurization and dust removal tank 14 through the pressure relief pipe 141. This avoids the situation where the sealing extrusion plate 113 is repeatedly pulled in and out of the pressure conveying tank 121, which would cause the gas pressure inside the desulfurization and dust removal tank 14 to be too high, and the flue gas cannot be discharged in time, thus leading to excessive flue gas pressure inside the desulfurization and dust removal tank 14 and increasing the pressure load.

[0039] like Figures 1 to 7 As shown, a sulfur gas conveying tank 114 is fixedly installed on the top surface of the foundation plate 11 and on the back of the desulfurization and dust removal tank 14. The bottom end of the sulfur gas conveying pipe 142 extends into the interior of the high-efficiency activated carbon 146. Two sets of flue gas recovery tanks 115 are arranged on both sides of the sulfur gas conveying tank 114. Three sets of guide pipes 116 are fixedly connected to the output ends of the sulfur gas conveying tank 114 and the flue gas recovery tank 115, respectively. One end of the guide pipe 116 extends to the top inner wall of the sulfur gas conveying pipe 142, and one end of the other two sets of guide pipes 116 extends to the top inner wall of the desulfurization and dust removal tank 14. Anti-sway platforms 12 are fixedly installed on the top surface of the foundation plate 11 and at the two side edges. The anti-sway platforms 12 are positioned at the pressure conveying tank 12. At the bottom edge of the foundation plate 11, a support frame 111 is fixedly installed on the top surface of the foundation plate 11. The top surface of the hydraulic rod 112 is fixedly installed on the bottom surface of the support frame 111. The pressure relief pipe 141 extends to the inner side of the desulfurization and dust removal tank 14, with one end located in the middle of the two sets of flue gas filter plates 144. A sealing cover 143 is fixedly installed on the top surface of the desulfurization and dust removal tank 14, and the outer surface of the sealing cover 143 is movably sleeved on the top outer surface of the sulfur gas conveying pipe 142. The surface of the flue gas filter layer 145 is movably overlapped on the top surface of the high-efficiency activated carbon 146. Two sets of cooling boxes 13 are fixedly installed on the top surface of the foundation plate 11, and the positions of the two sets of cooling boxes 13 are respectively located at the two side edges of the desulfurization and dust removal tank 14.

[0040] The flue gas inside the sulfur gas delivery tank 114 is pumped into the sulfur gas delivery pipe 142 through the guide pipe 116, and the impurity particles and sulfur gas inside the flue gas are purified by the high-efficiency activated carbon 146. The filtered flue gas is then injected into the flue gas recovery tank 115 through two other sets of guide pipes 116 for recovery.

[0041] When the flue gas moves back and forth inside the desulfurization and dust removal tank 14 and the pressure conveying tank 121, the pressure relief pipe 141 is used to relieve the pressure of the flue gas inside the desulfurization and dust removal tank 14 to avoid excessive pressure inside the desulfurization and dust removal tank 14 and increase the pressure load.

[0042] like Figures 1 to 3 and Figure 7 As shown, water source guide pipes 131 are fixedly installed on both sides of the cooling box 13, and dispersing guide pipes 133 are fixedly installed on both sides of the cooling box 13. A sealing cover 132 is movably fitted onto the top surface of the cooling box 13. One end of the dispersing guide pipe 133 is connected to one end of the air guide pipe. Multiple sets of cooling pipes 134 are fixedly installed on the outer surface of the dispersing guide pipe 133 and on the inner wall of the cooling box 13. The inner wall of the cooling box 13 and the outer surface of the cooling pipes 134 are filled with condensate.

[0043] When the flue gas moves back and forth inside the desulfurization and dust removal tank 14 and the pressure conveying tank 121, the flue gas will pass through the cooling pipe 134 through the differentiation guide pipe 133. Due to the large number of cooling pipes 134, the contact area and range with the condensate can be greatly increased. As a result, when the high-temperature flue gas passes through the cooling pipe 134, the condensate will quickly absorb heat and cool down the high temperature inside the flue gas. This prevents the adsorbed molecules in the micropores of the activated carbon from being desorbed by the high-temperature flue gas. At the same time, the pore size may become larger, thereby reducing the adsorption capacity and weakening the adsorption capacity of the activated carbon. In addition, the water source guide pipe 131 will quickly circulate the condensate inside the cooling tank 13 and cool down the flowing condensate through the water source guide pipe 131.

[0044] Working principle: The high-temperature flue gas is transported in conjunction with the sulfur gas conveying pipe 142 and directly injected into the center of the high-efficiency activated carbon 146. The high-efficiency activated carbon 146 is used to perform all-round dust removal and desulfurization treatment on the flue gas. As the gas is continuously filled and accumulated, the hot flue gas will gradually begin to rise. At this time, it comes into contact with the flue gas filter plate 144 that is attached to the high-efficiency activated carbon 146. The flue gas filter layer 145 on the outer surface of the flue gas filter plate 144 is used to filter the rising flue gas and some impurity particles that have not been completely filtered and dust removed.

[0045] When the flue gas remains inside the high-efficiency activated carbon 146, the sealing extrusion plate 113 is extended and retracted by the hydraulic rod 112. At this time, when the sealing extrusion plate 113 slides up and down on the inner wall of the suction and conveying tank 121, the desulfurized flue gas inside the desulfurization and dust removal tank 14 and the high-efficiency activated carbon 146 is extracted and pushed into the bottom cavity of the suction and conveying tank 121 by the gas. When the gas circulates and flows rapidly inside the high-efficiency activated carbon 146, it will accelerate the rapid penetration of the flue gas inside the high-efficiency activated carbon 146, thereby increasing the contact range and contact area between the flue gas and the high-efficiency activated carbon 146 and increasing the desulfurization effect of the flue gas.

[0046] When the sealing extrusion plate 113 presses down inside the pressure conveying tank 121, it will guide the flue gas inside the pressure conveying tank 121 back into the interior of the high-efficiency activated carbon 146, so that the flue gas and the high-efficiency activated carbon 146 will be repeatedly alternated, thereby achieving the effect of secondary desulfurization treatment of the flue gas.

[0047] When the hydraulic rod 112 presses down on the sealing extrusion plate 113, the flue gas inside the suction conveying tank 121 is magnetically injected into the desulfurization and dust removal tank 14. The accumulated flue gas will quickly move upward and cause the flue gas to pass through the flue gas filter layer 145 quickly. As the airflow passes through the flue gas filter layer 145 quickly, the impurity particles inside the flue gas will remain on the surface of the flue gas filter layer 145. When the hydraulic rod 112 pulls back on the sealing extrusion plate 113, under the reverse push of the flue gas, the flue gas filter layer 145 will bulge downward. At this time, the dust and impurities left on the bottom surface of the flue gas filter layer 145 will be guided by the gas to the interior of the high-efficiency activated carbon 146. By using the back and forth penetration of the gas, the dust particles inside the flue gas are filtered, removed, and peeled off.

[0048] When the sealing extrusion plate 113 on one end of the hydraulic rod 112 moves back and forth inside the pressure conveying tank 121, the cavity between the top of the sealing extrusion plate 113 and the pressure conveying tank 121 will draw gas from the inside of the pressure relief pipe 141, thereby guiding the filtered gas inside the desulfurization and dust removal tank 14 into the inside of the pressure conveying tank 121. When extruding in the reverse direction, the extracted flue gas can be re-injected into the inside of the desulfurization and dust removal tank 14 through the pressure relief pipe 141. This avoids the excessive air pressure inside the desulfurization and dust removal tank 14 caused by the repeated pulling of the sealing extrusion plate 113 inside the pressure conveying tank 121, which would prevent the flue gas from being discharged in time and thus increase the pressure load.

[0049] When the flue gas moves back and forth inside the desulfurization and dust removal tank 14 and the pressure conveying tank 121, the flue gas will pass through the cooling pipe 134 through the differentiation guide pipe 133. Due to the large number of cooling pipes 134, the contact area and range with the condensate can be greatly increased. As a result, when the high-temperature flue gas passes through the cooling pipe 134, the condensate will quickly absorb heat and cool down the high temperature inside the flue gas. This prevents the adsorbed molecules in the micropores of the activated carbon from being desorbed by the high-temperature flue gas. At the same time, the pore size may become larger, thereby reducing the adsorption capacity and weakening the adsorption capacity of the activated carbon. In addition, the water source guide pipe 131 will quickly circulate the condensate inside the cooling tank 13 and cool down the flowing condensate through the water source guide pipe 131.
