Abstract
Description
Technical Field
[0001] The invention relates to the technical field of regeneration towers, and in particular to a regeneration tower with an anti-clogging preheating section. Background Art
[0002] In the related art, the high-temperature flue gas generated by the boiler contains a large amount of sulfide and nitrogen oxide, and the flue gas needs to be desulfurized and denitrified before it can be discharged into the atmosphere. At present, high-temperature flue gas is generally desulfurized and denitrified through an adsorption tower. Specifically, the high-temperature flue gas is passed into the adsorption tower, and the pollutants (sulfide and nitrogen oxide) in the high-temperature flue gas are adsorbed and removed by the adsorbent in the adsorption tower. The adsorbent saturated with adsorption is transported to the regeneration tower for heating and desorption regeneration. The pollutants are desorbed from the adsorbent and recycled, and the adsorbent is regenerated. However, when the adsorbent saturated with adsorption returns to the regeneration tower, due to the large friction between the adsorbents, the adsorbent is easily blocked in the preheating section, resulting in a low regeneration efficiency of the adsorbent. Summary of the invention
[0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. To this end, an embodiment of the present invention provides a regeneration tower, so that the regeneration tower of the present invention has the advantages of anti-blocking function of the preheating section and high adsorbent regeneration efficiency.
[0004] The regeneration tower of the embodiment of the present invention comprises a tower body and a rapping assembly, wherein the tower body has a preheating section, the preheating section has an adsorbent inlet, the preheating section is used to preheat the adsorbent to be regenerated entering the tower body to a first temperature, and the side wall of the preheating section has a first through hole;
[0005] The rapping assembly includes a vibration rod, a vibration plate, a vibration spring and a vibration motor. The vibration rod extends into the preheating section through the first through hole. The vibration plate is arranged in the preheating section and connected to the vibration rod. The vibration spring is arranged between the vibration rod and the side wall of the preheating section to give the vibration rod an elastic force along its axial direction. The vibration motor is arranged outside the preheating section and connected to the vibration rod to drive the vibration rod to vibrate in its axial direction.
[0006] During the operation of the regeneration tower of the embodiment of the present invention, the adsorbent to be regenerated enters the preheating section through the adsorbent inlet. When the adsorbent to be regenerated is blocked in the preheating section due to excessive intermolecular forces, the vibration motor is turned on, so that the vibration rod reciprocates along its axial direction under the action of the vibration motor and the vibration spring. The vibration rod drives the vibration plate to vibrate, and the vibration of the vibration plate reciprocates the blocked adsorbent to reduce the forces between adjacent adsorbents, so that the adsorbent can be discharged smoothly, avoiding blockage of the adsorbent in the preheating section, and improving the regeneration efficiency of the adsorbent.
[0007] Therefore, the regeneration tower of the embodiment of the present invention has the advantages of anti-clogging function of the preheating section and high adsorbent regeneration efficiency.
[0008] Optionally, the vibration plate is tilted. Since there is a large material discharge space above the preheating section, by tilting the vibration plate, the vibration plate can push the adsorbent to move in the up and down directions for tumbling, which is convenient for the flow of the adsorbent in the preheating section, further reduces the force between adjacent adsorbents, further increases the material discharge speed of the adsorbent, and improves the adsorbent regeneration efficiency.
[0009] Optionally, the angle between the vibration plate and the horizontal plane is 20°-40°. When the angle between the vibration plate and the horizontal plane is set too small, the effective pushing area of the vibration plate will be too small, and the vibration effect will be poor. When the angle between the vibration plate and the horizontal plane is set too large, the effective pushing area of the vibration plate will be too large, the resistance of the adsorbent to the vibration plate will be too large, and the vibration plate will be easily deformed by stress, which will affect its service life.
[0010] Optionally, the vibration plate has a plurality of feed holes arranged at intervals. When the adsorbent is discharged from the adsorbent inlet, the dropped adsorbent can fall through the feed holes on the vibration plate to the distribution space below the vibration plate, so as to fall into the next processing stage of the tower body, which is beneficial to improve the working reliability of the regeneration tower. In addition, when the adsorbent is blocked in the preheating section, the adsorbent can also shuttle on both sides of the thickness direction of the vibration plate through the feed holes during the vibration of the vibration plate, which can reduce the vibration resistance of the vibration plate and change the interaction force between adjacent adsorbents, so that adjacent adsorbents are easily separated to avoid blockage.
[0011] Optionally, the diameter of the feed hole is 10mm-20mm.
[0012] Optionally, the vibration spring includes a first spring and a second spring, the vibration rod has a stop portion located outside the preheating section, the first spring is located outside the preheating section and two ends of the first spring respectively stop on the stop portion and the outer wall of the preheating section, the second spring is located inside the preheating section and two ends of the second spring respectively stop on the vibration plate and the inner wall of the preheating section, thereby facilitating the installation of the first spring and the second spring.
[0013] Optionally, the first through hole is a square hole, the outer peripheral contour of the cross section of the vibration rod is a square, and the vibration rod is slidably matched with the first through hole along its axial direction. When the vibration rod is vibrating, the vibration rod can be positioned to prevent the vibration rod from rotating during the vibration process and affecting the vibration effect of the vibration plate.
[0014] Optionally, the first temperature is 70°C-100°C.
[0015] Optionally, the tower body further includes a heating section and a cooling section, wherein the preheating section, the heating section and the cooling section are arranged in sequence from top to bottom, the heating section is connected to the preheating section and the cooling section respectively, the heating section is used to heat and desorb the regenerated adsorbent, and the cooling section is used to cool the regenerated adsorbent to 15°C-35°C. The lower the temperature of the adsorbent, the better the adsorption effect, and by cooling the adsorbent to 15°C-35°C, the adsorption efficiency can be improved after the adsorbent is returned to the adsorption tower.
[0016] Optionally, the cooling section has a cooling gas inlet, which is used to deliver room temperature air into the cooling section. Room temperature air is easy to obtain, which is conducive to saving cooling costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.
[0023] The technical solution of the present application is described in detail below with reference to the accompanying drawings.
[0024] like Figures 1 to 3 As shown, the regeneration tower 100 of the embodiment of the present invention includes a tower body 1 and a rapping assembly 2. The tower body 1 has a preheating section 101, and the preheating section 101 has an adsorbent inlet 1011. The preheating section 101 is used to preheat the adsorbent to be regenerated entering the tower body 1 to a first temperature, and the side wall of the preheating section 101 has a first through hole (not marked in the figure).
[0025] The rapping assembly 2 includes a vibration rod 201, a vibration plate 202, a vibration spring 203 and a vibration motor 204. The vibration rod 201 extends into the preheating section 101 through the first through hole, the vibration plate 202 is arranged in the preheating section 101 and connected to the vibration rod 201, the vibration spring 203 is arranged between the vibration rod 201 and the side wall of the preheating section 101 to give the vibration rod 201 an elastic force along its axial direction, and the vibration motor 204 is arranged outside the preheating section 101 and connected to the vibration rod 201 to drive the vibration rod 201 to vibrate in its axial direction.
[0026] For example, Figure 1 As shown, the vibration motor 204 includes a driving motor and an eccentric disk. The eccentric disk is installed on the output shaft of the driving motor. The axial direction of the output shaft of the driving motor is consistent with the axial direction of the vibration rod 201. The eccentric disk has an eccentric force during rotation to drive the vibration rod 201 to reciprocate and vibrate in its axial direction.
[0027] During operation of the regeneration tower 100 of the embodiment of the present invention, the adsorbent to be regenerated enters the preheating section 101 through the adsorbent inlet 1011. When the adsorbent to be regenerated is blocked in the preheating section 101 due to excessive intermolecular forces, the vibration motor 204 is turned on, so that the vibration rod 201 reciprocates along its axial direction under the action of the vibration motor 204 and the vibration spring 203. The vibration rod 201 drives the vibration plate 202 to vibrate, and the vibration of the vibration plate 202 reciprocates the blocked adsorbent to reduce the forces between adjacent adsorbents, so that the adsorbent can be discharged smoothly, and the adsorbent is prevented from being blocked in the preheating section 101, thereby improving the regeneration efficiency of the adsorbent.
[0028] Therefore, the regeneration tower 100 of the embodiment of the present invention has the advantages of anti-clogging function of the preheating section 101 and high adsorbent regeneration efficiency.
[0029] Optionally, the vibration plate 202 is arranged to be inclined.
[0030] For example, Figure 2 and Figure 3 As shown, since there is a large unloading space above the preheating section 101, the vibration plate 202 is tilted so that the vibration plate 202 can push the adsorbent to move in the up and down directions for rolling, thereby facilitating the flow of the adsorbent in the preheating section 101, further reducing the force between adjacent adsorbents, further increasing the unloading speed of the adsorbent, and improving the adsorbent regeneration efficiency.
[0031] In some embodiments, the angle between the vibration plate 202 and the horizontal plane is 20°-40°.
[0032] For example, the angle between the vibration plate 202 and the horizontal plane can be 20°, 30° or 40°. If the angle between the vibration plate 202 and the horizontal plane is set too small, the effective pushing area of the vibration plate 202 will be too small, and the vibration effect will be poor. If the angle between the vibration plate 202 and the horizontal plane is set too large, the effective pushing area of the vibration plate 202 will be too large, the resistance of the adsorbent to the vibration plate 202 will be too large, and the vibration plate 202 will be easily deformed by stress, which will affect its service life.
[0033] Optionally, the vibration plate 202 has a plurality of feed holes 2021 arranged at intervals.
[0034] like Figure 3 As shown, when the adsorbent is discharged from the adsorbent inlet 1011, the dropped adsorbent can fall through the feeding hole 2021 on the vibration plate 202 to the distribution space below the vibration plate 202, so as to fall into the next processing stage of the tower body 1, which is beneficial to improve the working reliability of the regeneration tower 100. In addition, when the adsorbent is blocked in the preheating section 101, the adsorbent can also shuttle on both sides of the thickness direction of the vibration plate 202 through the feeding hole 2021 during the vibration of the vibration plate 202, while reducing the vibration resistance of the vibration plate 202, and can also change the interaction force between adjacent adsorbents, so that adjacent adsorbents are easily separated to avoid blockage.
[0035] Optionally, the diameter of the feed hole 2021 is 10 mm-20 mm. For example, the diameter of the feed hole 2021 can be 10 mm, 15 mm or 20 mm.
[0036] In some embodiments, the vibration spring 203 includes a first spring 2031 and a second spring 2032. The vibration rod 201 has a stop portion 2011 located outside the preheating section 101, the first spring 2031 is located outside the preheating section 101 and the two ends of the first spring 2031 are respectively stopped on the stop portion 2011 and the outer wall of the preheating section 101, and the second spring 2032 is located inside the preheating section 101 and the two ends of the second spring 2032 are respectively stopped on the vibration plate 202 and the inner wall of the preheating section 101.
[0037] like Figure 2 and Figure 3 As shown, the first spring 2031 is sleeved on the vibration rod 201, and the two ends of the first spring 2031 are respectively stopped on the stop portion 2011 and the outer wall of the preheating section 101, and the second spring 2032 is sleeved on the vibration rod 201, and the two ends of the second spring 2032 are respectively stopped on the vibration plate 202 and the inner wall of the preheating section 101, so that the first spring 2031 and the second spring 2032 are easy to install.
[0038] Specifically, when the vibration rod 201 moves away from the preheating section 101, the first spring 2031 is stretched and the second spring 2032 is compressed; when the vibration rod 201 moves toward the preheating section 101, the first spring 2031 is compressed and the second spring 2032 is stretched. The vibration rod 201 reciprocates under the elastic force of the first spring 2031 and the second spring 2032, which is beneficial to improve the buffering effect of the vibration rod 201 and the service life of the spring.
[0039] In some embodiments, Figure 2 and Figure 3 As shown, the first through hole is a square hole, the outer peripheral contour of the cross section of the vibration rod 201 is a square, and the vibration rod 201 can be slidably matched with the first through hole along its axial direction. By setting the outer peripheral contour of the cross section of the vibration rod 201 to be a square to match the first through hole, the vibration rod 201 can be positioned during the vibration process to prevent the vibration rod 201 from rotating during the vibration process and affecting the vibration effect of the vibration plate 202.
[0040] Optionally, the first temperature is 70° C.-100° C. For example, the first temperature may be 70° C., 80° C. or 100° C. It is understandable that the adsorbent to be regenerated will be desorbed and regenerated at about 300° C., and preheating the adsorbent to be regenerated to 70° C.-100° C. can further improve the heating desorption regeneration efficiency of the adsorbent.
[0041] In some embodiments, the tower body 1 also includes a heating section 102 and a cooling section 103. The preheating section 101, the heating section 102 and the cooling section 103 are arranged in sequence from top to bottom. The heating section 102 is connected to the preheating section 101 and the cooling section 103 respectively. The heating section 102 is used to heat and desorb the regenerated adsorbent, and the cooling section 103 is used to cool the regenerated adsorbent to 15°C-35°C.
[0042] For example, Figure 2 As shown, after being preheated in the preheating section 101, the adsorbent enters the heating section 102 for heating desorption regeneration, and the regenerated adsorbent enters the cooling section 103 for cooling to 15° C., 25° C. or 35° C. It can be understood that the adsorption efficiency of the adsorbent is negatively correlated with the temperature, that is, the lower the temperature of the adsorbent, the better the adsorption effect. By cooling the adsorbent to 15° C.-35° C., the adsorption efficiency can be improved after the adsorbent is returned to the adsorption tower.
[0043] Optionally, the cooling section 103 has a cooling gas inlet 1031, and the cooling gas inlet 1031 is used to transport room temperature air into the cooling section 103. The room temperature air is easy to obtain, which is conducive to saving cooling costs.
