Technical Field

[0001] The present invention relates to the technical field of desulfurizer preparation, and specifically to a preparation device for a highly active desulfurizer for semi-dry desulfurization. Background Art

[0002] The semi-dry desulfurization technology has been widely used in the field of industrial flue gas desulfurization due to its advantages such as relatively high desulfurization efficiency, relatively simple equipment, and no wastewater discharge. And a highly active desulfurizer plays a key role in improving the semi-dry desulfurization efficiency. There are many problems in traditional desulfurizer preparation devices. For example, the contact time between lime water and sulfur-containing flue gas is short, and the reaction is not sufficient, resulting in unstable proportions of the components of the desulfurizer and affecting the desulfurization activity; the reaction process is difficult to accurately control, making the activity of the desulfurizer unable to reach the optimal state; and the energy consumption in the preparation process is high, increasing the production cost. In the prior art, although there are some improvement measures for desulfurizer preparation, the above problems still cannot be well solved, which limits the further development and application of the semi-dry desulfurization technology.

[0003] The existing semi-dry desulfurization preparation device has problems such as short contact time between lime water and sulfur-containing flue gas, insufficient reaction, difficult accurate control of the reaction process, and high energy consumption, thus affecting the preparation efficiency of a highly active desulfurizer.

At the top of the preparation stirring member, a motor is fixedly installed, and the motor is fixedly installed at the middle of the top of the sealing cover; A cleaning spray assembly, which is used for scraping off the desulfurizer raw materials attached to the surface of the preparation stirring member. On the surface of the cleaning spray assembly, an inner layer tank is fixedly installed, the inner layer tank is fixedly installed inside the cavity of the liquid collection tank, the inner layer tank is sleeved on the outer surface of the preparation stirring member, and the cleaning spray assembly is frictionally adapted to the preparation stirring member; Active filter element, the active filter element is used to filter the flue gas discharged after the desulfurizer raw material reacts. The active filter element is fixedly installed on one side of the outer surface of the sealing cover, and the active filter element is connected to the inner tank. During the desulfurizer preparation process, the staff opens the valve to allow the sulfur-containing flue gas produced by the preparation to be transported from the air guide port at the bottom of the inner tank to the cavity of the inner tank. At the same time, the staff injects lime water into the liquid collecting tank through the liquid guide port, and opens the nozzle installed in the cleaning spray assembly to spray lime water into the inner tank. The motor drives the preparation stirring element to rotate in the inner tank, so that the sulfur-containing flue gas and the lime water are fully digested and reacted to desulfurize the flue gas. The flue gas after desulfurization is transported to the top of the inner tank to the active filter element. At this time, the activated carbon particles in the active filter element adsorb the flue gas to filter the discharged flue gas.

[0005] Preferably, the preparation stirring member includes a stirring rod, a connecting shaft is fixedly installed on the top of the stirring rod, and a clip is sleeved on the outer surface of the stirring rod. There are three clips, and a stirring member is fixedly installed inside each of the three clips. When the sulfur-containing flue gas is transported into the inner tank, the cleaning spray assembly sprays lime water downward from the top of the inner tank. At this time, the output end of the motor drives the stirring rod and the stirring member to rotate in the inner tank so that the flue gas that is drifting out will be stirred and mixed more evenly when it comes into contact with the lime water to produce a digestion reaction. The stirring member is provided with a multi-layer hollow structure. When rotating at high speed, the flue gas passes through the hollow structure, and the flue gas is temporarily intercepted to extend the digestion reaction time between the flue gas and the lime water, thereby improving the preparation efficiency.

[0006] Preferably, the stirring rod is fixedly mounted on the output end of the motor through a connecting shaft, and three groups of stirring parts are provided. The three groups of stirring parts are spirally distributed on the surface of the stirring rod through snap-on pieces. The stirring parts are rotatably mounted inside the cavity of the inner tank through a connecting shaft, and the stirring parts are frictionally adapted to the cleaning spray assembly.

[0007] Preferably, the mixing element includes a positioning frame having a surface provided with segmented grooves. The segmented grooves are provided in four groups, and the four groups of segmented grooves are symmetrically arranged around the positioning frame. Dispersing discs are fixedly installed inside the segmented grooves. The solid product formed after the reaction of sulfur-containing flue gas and lime water falls above the opening and closing valve to collect the solid product. At this time, the rotating positioning frame drives the dispersing discs to grind the solid product, so that the lime contained in the solid product tends to be rationalized after grinding, which is conducive to improving its hydration performance. The dispersing discs generate friction with the segmented grooves and the material-selecting discs during rotation to clean the solid product attached to the positioning frame during the reaction.

[0008] Preferably, the positioning frame is fixedly installed inside the clamping piece, the dispersion piece is made of elastic material, and the dispersion piece is extruded and adapted to the segmented groove.

[0009] Preferably, the cleaning spray assembly includes an internal frame, a spray port is provided on the surface of the internal frame, a support plate is fixedly installed on the top of the internal frame, four support plates are provided, and the four support plates are distributed in a circular shape on the surface of the internal frame, a connecting ring is fixedly installed inside the support plate, an extension rod is fixedly installed on the bottom of the connecting ring, an opening and closing valve is fixedly installed on the bottom of the extension rod, a block is fixedly installed on the surface of the extension rod, and a material stripper is fixedly installed inside the block. The staff transports the sulfur-containing flue gas into the inner tank, and the nozzle installed in the spray port sprays lime water into the inner tank. When the lime water reacts with the sulfur-containing flue gas, the solidified product easily adheres to the inner tank and the surface of the preparation stirring member. At this time, the material stripper installed on the surface of the extension rod is squeezed with the dispersion sheet in the segmented tank when the preparation stirring member rotates, causing the dispersion sheet to bounce and shake off the solidified product on the preparation stirring member.

[0010] Preferably, the inner frame is sleeved above the outer surface of the inner tank, the inner frame is fixedly connected to the inner wall of the liquid collecting tank, four extension rods are provided, and the four extension rods are fixedly installed on the inner wall of the inner tank, and the material-shifting piece is frictionally adapted to the segmented groove.

[0012] Preferably, the exhaust pipe is fixedly mounted on one side of the outer surface of the sealing cover, the exhaust pipe being connected to the sealing cover via an air guide filter plate, the toggle being rotatably mounted inside the exhaust pipe, and the toggle being frictionally engaged with the air guide filter plate. Flue gas after the digestion reaction is discharged upward along the inner tank and transported into the air guide filter plate. At this time, the flowing airflow is injected into the exhaust pipe, which drives the toggle to rotate on the shaft, thereby allowing the flue gas to fully contact the activated carbon particles in the exhaust pipe, allowing the activated carbon particles to adsorb impurities in the flue gas, and the filtered flue gas is discharged from the exhaust filter plate.

[0013] Preferably, the toggle member includes a rotating frame, which is rotatably mounted on the outer surface of the rotating shaft.

The surfaces of the toggle plates are respectively provided with air guide holes and inner grooves. The toggle plates are frictionally adapted to the air guide filter plate and the exhaust filter plate. When the airflow pushes the rotating frame to rotate on the rotating shaft, the rotating frame drives the toggle plates and the bent rods on both sides to rotate. The air guide holes provided on the surfaces of the toggle plates allow for airflow. When the toggle plates rotate, they rub against the inner walls of the air guide filter plate and the exhaust filter plate to scrape off impurities attached to the filter plates, thereby preventing clogging of the filter plates.

[0014] The present invention provides a device for preparing a highly active desulfurizing agent for semi-dry desulfurization, which has the following beneficial effects: 1. The preparation device of the highly active desulfurizer for semi-dry desulfurization is as follows: during the preparation process of the desulfurizer, the staff opens the valve to transport the sulfur-containing flue gas generated by the preparation from the air guide port below the inner tank to the cavity of the inner tank. At the same time, the staff injects lime water into the liquid collecting tank through the liquid guide port, and opens the nozzle installed in the cleaning spray assembly to spray lime water into the inner tank. The motor drives the preparation stirring element to rotate in the inner tank, so that the sulfur-containing flue gas and the lime water are fully digested and reacted to desulfurize the flue gas. The flue gas after desulfurization is transported to the top of the inner tank to the active filter element. At this time, the activated carbon particles in the active filter element adsorb the flue gas to filter the discharged flue gas.

[0015] 2. The preparation device of the high-activity desulfurizer for semi-dry desulfurization is characterized in that when the sulfur-containing flue gas is transported into the inner tank, the cleaning spray assembly sprays lime water downward from the top of the inner tank. At this time, the output end of the motor drives the stirring rod and the stirring element to rotate in the inner tank so that the flue gas drifting toward the inner tank can be stirred and mixed more evenly when it contacts the lime water to produce a digestion reaction. The stirring element is provided with a multi-layer hollow structure, which allows the flue gas to pass through the hollow structure when rotating at high speed, and temporarily intercepts the flue gas to extend the digestion reaction time of the flue gas and lime water, thereby improving the preparation efficiency.

[0016] 3. The preparation device of the high-activity desulfurizer for semi-dry desulfurization is a device in which the solid product formed after the reaction of sulfur-containing flue gas and lime water falls above the opening and closing valve to collect the solid product. At this time, the rotating positioning frame drives the dispersion sheet to grind the solid product so that the lime contained in the solid product tends to be rationalized after grinding, which is beneficial to improving its hydration performance. The dispersion sheet generates friction with the segmented trough and the material-selecting sheet during rotation to clean the solid product attached to the positioning frame during the reaction.

[0017] 4. The preparation device of the highly active desulfurizer for semi-dry desulfurization is that the staff transports the sulfur-containing flue gas into the inner tank, and the nozzle installed in the spray port sprays lime water into the inner tank. When the lime water reacts with the sulfur-containing flue gas, the solidified product easily adheres to the surface of the inner tank and the preparation stirring piece. At this time, the material-prying piece installed on the surface of the extension rod is squeezed with the dispersion piece in the segmented groove when the preparation stirring piece rotates, causing the dispersion piece to bounce and vibrate the solidified product on the preparation stirring piece.

[0018] 5. The preparation device of the highly active desulfurizer for semi-dry desulfurization is characterized in that the flue gas after the digestion reaction is discharged upward along the inner tank and transported into the air guide filter plate. At this time, the flowing airflow is injected into the exhaust pipe, and the airflow pushes the toggle piece to rotate on the rotating shaft, so that the flue gas is fully in contact with the activated carbon particles in the exhaust pipe, so that the activated carbon particles adsorb impurities in the flue gas, and the filtered flue gas is discharged from the exhaust filter plate; when the airflow pushes the rotating frame to rotate on the rotating shaft, the rotating frame drives the toggle pieces and the bent rods on both sides to rotate, and the air guide holes opened on the surface of the toggle piece are used for airflow circulation. When the toggle piece rotates, it will generate friction with the inner walls of the air guide filter plate and the exhaust filter plate to scrape off impurities attached to the filter plate, thereby avoiding clogging of the filter plate.

The inner layer tank 7 is sleeved on the outer surface of the stirring member 8. The cleaning spray assembly 6 is friction-fitted with the stirring member 8. The active filter element 4 is used to filter the flue gas discharged after the desulfurizer raw material reacts. The active filter element 4 is fixedly installed on one side of the outer surface of the sealing cover 2, and the active filter element 4 is connected to the inner tank 7. During the desulfurizer preparation process, the staff opens the valve to allow the sulfur-containing flue gas produced by the preparation to be transported from the air guide port below the inner tank 7 to the cavity of the inner tank 7. At the same time, the staff injects lime water into the liquid collecting tank 9 through the liquid guide port 3, and opens the nozzle installed in the cleaning spray assembly 6 to spray lime water into the inner tank 7. The motor 1 drives the preparation stirring element 8 to rotate in the inner tank 7, so that the sulfur-containing flue gas and the lime water are fully digested and reacted to desulfurize the flue gas. The flue gas after desulfurization is transported to the top of the inner tank 7 to the active filter element 4. At this time, the activated carbon particles in the active filter element 4 adsorb the flue gas to filter the discharged flue gas.

[0023] The active filter element 4 includes an exhaust pipe 41, an air guide filter plate 45 is fixedly installed on the surface of the exhaust pipe 41 close to the sealing cover 2, activated carbon particles are placed inside the exhaust pipe 41, a rotating shaft 44 is rotatably installed inside the exhaust pipe 41, a toggle member 42 is rotatably installed on the surface of the rotating shaft 44, and an exhaust filter plate 43 is fixedly installed on the surface of the exhaust pipe 41 away from the air guide filter plate 45.

[0024] The exhaust pipe 41 is fixedly mounted on one side of the outer surface of the sealing cover 2. The exhaust pipe 41 is connected to the sealing cover 2 through the air guide filter plate 45.

When the toggle plate 422 rotates, it rubs against the inner walls of the air guide filter plate 45 and the exhaust filter plate 43 to scrape off impurities attached to the filter plates, thereby preventing clogging of the filter plates.

[0026] Second Embodiment. On the basis of the first embodiment, please refer to Figures 3 to 6 As shown, the preparation stirring member 8 includes a stirring rod 82. A connecting shaft 84 is fixedly installed at the top of the stirring rod 82. A clamping piece 83 is sleeved on the outer surface of the stirring rod 82. There are three clamping pieces 83, and a stirring member 81 is fixedly installed inside each of the three clamping pieces 83. When the sulfur-containing flue gas is transported into the inner tank 7, the cleaning spray assembly 6 sprays lime water downward from the upper direction of the inner tank 7. At this time, the output end of the motor 1 drives the stirring rod 82 and the stirring member 81 to rotate inside the inner tank 7, so that when the dispersed flue gas reacts with the lime water to produce a digestion reaction, it is stirred and mixed more evenly by the stirring member 81. And the stirring member 81 is provided with a multi-layer hollow structure. When rotating at a high speed, the flue gas passes through the hollow to intercept the flue gas briefly to extend the digestion reaction time of the flue gas and the lime water, thereby improving the preparation efficiency.

[0027] The stirring rod 82 is fixedly installed at the output end of the motor 1 through the connecting shaft 84. There are three groups of stirring members 81. The three groups of stirring members 81 are spirally distributed on the surface of the stirring rod 82 through the clamping pieces 83.

[0028] The stirring member 81 includes a positioning frame 811. Segmented grooves 813 are formed on the surface of the positioning frame 811. There are four groups of segmented grooves 813, and the four groups of segmented grooves 813 are symmetrically arranged with the positioning frame 811 as the center. Dispersion plates 812 are fixedly installed inside each of the segmented grooves 813. The solid product formed after the reaction of the sulfur-containing flue gas and the lime water falls above the opening and closing valve 67 to collect the solid product. At this time, the rotating positioning frame 811 drives the dispersion plates 812 to grind the solid product, so that the lime contained in the solid product becomes more reasonable after grinding, which is beneficial to improving its hydration performance. The dispersion plates 812 generate friction with the segmented grooves 813 and the feeding blades 66 during rotation to clean the solid product attached to the positioning frame 811 during the reaction.

[0029] The positioning frame 811 is fixedly installed inside the clamping piece 83. The dispersion plate 812 is made of an elastic material, and the dispersion plate 812 is extrusion-fitted with the segmented groove 813.

[0030] Third Embodiment. On the basis of the first and second embodiments, please refer to Figures 7 to 8As shown, the cleaning spray assembly 6 includes an internal frame 61, a spray port 68 is provided on the surface of the internal frame 61, a support plate 64 is fixedly installed on the top of the internal frame 61, four support plates 64 are provided, and the four support plates 64 are distributed in a circular shape on the surface of the internal frame 61, a connecting ring 62 is fixedly installed inside the support plate 64, an extension rod 63 is fixedly installed at the bottom of the connecting ring 62, an opening and closing valve 67 is fixedly installed at the bottom of the extension rod 63, a clamping block 65 is fixedly installed on the surface of the extension rod 63, and a prying piece 66 is fixedly installed inside the clamping block 65. The staff transports the sulfur-containing flue gas into the inner tank 7. At this time, the nozzle installed in the spray port 68 sprays lime water into the inner tank 7. When the lime water reacts with the sulfur-containing flue gas, the solidified product easily adheres to the surface of the inner tank 7 and the preparation stirring member 8. At this time, the material-dispensing piece 66 installed on the surface of the extension rod 63 is squeezed with the dispersion piece 812 in the segmented groove 813 when the preparation stirring member 8 rotates, causing the dispersion piece 812 to bounce and vibrate off the solidified product on the preparation stirring member 8.

[0031] The inner frame 61 is sleeved above the outer surface of the inner tank 7, and the inner frame 61 is fixedly connected to the inner wall of the liquid collecting tank 9. Four extension rods 63 are provided, and the four extension rods 63 are fixedly installed on the inner wall of the inner tank 7. The material-shifting piece 66 is frictionally adapted to the segmented groove 813.

[0032] During use, during the preparation of the desulfurizer, the staff opens the valve to transport the sulfur-containing flue gas produced by the preparation from the air guide port below the inner tank 7 to the cavity of the inner tank 7. At the same time, the staff injects lime water into the liquid collecting tank 9 through the liquid guide port 3, and opens the nozzle installed in the cleaning spray assembly 6 to spray lime water into the inner tank 7. The motor 1 drives the preparation stirring element 8 to rotate in the inner tank 7, so that the sulfur-containing flue gas and the lime water are fully digested and reacted to desulfurize the flue gas. The flue gas after desulfurization is transported to the top of the inner tank 7 to the active filter element 4. At this time, the activated carbon particles in the active filter element 4 adsorb the flue gas to filter the discharged flue gas.

[0033] When the sulfur-containing flue gas is transported to the inner tank 7, the cleaning spray assembly 6 sprays lime water downward from the top of the inner tank 7. At this time, the output end of the motor 1 drives the stirring rod 82 and the stirring element 81 to rotate in the inner tank 7 so that the flue gas that is drifting in the direction of the flue gas contacts with the lime water to produce a digestion reaction. The stirring element 81 is stirred and mixed more evenly, and a multi-layer hollow structure is set inside the stirring element 81. When rotating at a high speed, the flue gas passes through the hollow structure and is temporarily intercepted to extend the digestion reaction time of the flue gas and lime water, thereby improving the preparation efficiency.

[0034] The solid product formed after the sulfur-containing flue gas reacts with lime water falls above the opening and closing valve 67 to collect the solid product. At this time, the rotating positioning frame 811 drives the dispersion sheet 812 to grind the solid product so that the lime contained in the solid product tends to be rationalized after grinding, which is beneficial to improving its hydration performance. When rotating, the dispersion sheet 812 generates friction with the segmented groove 813 and the material-selecting sheet 66 to clean the solid product attached to the positioning frame 811 during the reaction.

[0035] The staff transports the sulfur-containing flue gas into the inner tank 7. At this time, the nozzle installed in the spray port 68 sprays lime water into the inner tank 7. When the lime water reacts with the sulfur-containing flue gas, the solidified product easily adheres to the surface of the inner tank 7 and the preparation stirring member 8. At this time, the material-dispensing piece 66 installed on the surface of the extension rod 63 is squeezed with the dispersion piece 812 in the segmented groove 813 when the preparation stirring member 8 rotates, causing the dispersion piece 812 to bounce and vibrate off the solidified product on the preparation stirring member 8.

[0036] The flue gas after the digestion reaction is discharged upward along the inner tank 7 and transported into the air guide filter plate 45. At this time, the flowing air flow is injected into the exhaust pipe 41, and the air flow pushes the toggle piece 42 to rotate on the rotating shaft 44, so that the flue gas is fully in contact with the activated carbon particles in the exhaust pipe 41, so that the activated carbon particles can adsorb impurities in the flue gas, and the filtered flue gas is discharged from the exhaust filter plate 43; when the air flow pushes the rotating frame 421 to rotate on the rotating shaft 44, the rotating frame 421 drives the toggle pieces 422 and the bent rods 423 on both sides to rotate, and the air guide holes 424 opened on the surface of the toggle piece 422 are used for air flow circulation. When the toggle piece 422 rotates, it will generate friction with the inner walls of the air guide filter plate 45 and the exhaust filter plate 43 to scrape off impurities attached to the filter plate, thereby avoiding clogging of the filter plate.
