Description

Technical Field

[0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a waste gas treatment adsorption tower similar to radial adsorption. Background Art

[0002] In the field of environmental protection, the treatment of wastewater, waste gas and solid waste is a core issue. The waste gas generated during the treatment of wastewater and solid waste not only affects the living environment and residents' health, but also damages the atmospheric environment and causes the greenhouse effect. Therefore, it needs to be purified before being discharged into the atmospheric environment. Currently, the commonly used waste gas treatments mainly include absorption, adsorption, condensation and combustion. The absorption method is suitable for waste gas with low temperature and medium and high concentrations. It needs to be equipped with recovery devices such as heating analysis and condensation. The installed volume is large, the investment is large, and there is secondary pollution. The condensation method requires refrigeration equipment, which has large investment, high energy consumption, and high operating costs. After condensation, the tail gas still contains a certain concentration of organic matter. The combustion method can convert harmful substances into harmless substances. It requires auxiliary fuels, has high operating costs, and may produce new pollutants such as nitrogen oxides.

[0003] The adsorption method is applicable to a wide range of pollutant types and concentrations, has simple equipment, moderate cost, and low energy consumption. It is currently the main method for large-scale waste gas treatment. At present, most absorption towers are filled with adsorption materials. The waste gas passes through the adsorption material from bottom to top. After adsorption, the produced gas is discharged from the outlet on the top. This structural form has unstable utilization of the adsorption material. After long-term use, the fixed bed formed by the adsorption material is prone to uneven accumulation, which makes different parts have different resistance to the gas, resulting in uneven gas flow and insufficient adsorption. In addition, the gas always contacts the lower adsorption material first and then the upper adsorption material. The lower adsorption material is saturated with adsorption first, but the air intake of the adsorption tower still has to pass through the lower adsorption material, resulting in low adsorption efficiency. Summary of the invention

DETAILED DESCRIPTION

[0035] This embodiment provides a radial adsorption exhaust gas treatment adsorption tower, such as Figure 1-Figure 7 As shown, it includes a main tower 1, and an air inlet 2 is provided at the bottom of the main tower 1 to input exhaust gas into the main tower 1;

[0036] The interior of the main tower 1 includes an air inlet area 4, an adsorption area and an air outlet area 5 from the outside to the inside. The air outlet area 5 is located in the center of the main tower 1 and is vertically arranged. The bottom of the air outlet area 5 is connected to the lower part of the side wall of the main tower 1 through an air outlet pipe 6 for exhausting gas.

[0037] The adsorption zone is arranged around the outer side of the gas outlet zone 5, and the gas inlet zone 4 is between the adsorption zone and the side wall of the main tower 1, and the gas inlet 2 is connected to the bottom of the gas inlet zone 4;

[0038] The adsorption zone includes an outer adsorption zone and an inner adsorption zone from the outside to the inside. The outer adsorption zone includes a plurality of rotating adsorption strings 7, which are arranged around the inner adsorption zone. The inner adsorption zone includes a plurality of shielded adsorption strings 8 that can move upward, which are arranged around the outlet zone 5. The position between the two rotating adsorption strings 7 corresponds to a shielded adsorption string 8. The intake air of the intake zone 4 passes through the outer adsorption zone and the inner adsorption zone in turn, and is then discharged from the outlet zone 5.

[0039] Optionally, the main body is vertical and is selected from a cylindrical or cubic shape.

[0040] Optionally, an air intake baffle 9 is provided at the bottom of the main tower 1, and the outer diameter of the air intake baffle 9 is not less than the outer diameter of the outer adsorption zone. Between the air intake baffle 9 and the bottom plate of the main tower 1 is a part of the air intake zone 4. The air inlet 2 is located below the air intake baffle 9. The intake air is blocked by the air intake baffle 9 and flows along the air intake baffle 9, that is, along the radial direction of the main tower 1, toward the side wall of the main tower 1, and flows upward after passing the outer edge of the air intake baffle 9.

[0041] Optionally, the top end of the air outlet pipe 6 is connected to the bottom of the air outlet area 5 , the air outlet pipe 6 passes through the air inlet area 4 at the bottom of the main tower 1 and the bottom plate of the main tower 1 , and the bottom end outlet of the air outlet pipe 6 is outside the main tower 1 .

[0042] Optionally, the plurality of rotating adsorption strings 7 of the outer adsorption zone are evenly arranged along the edge of the adsorption zone with the vertical central axis of the main tower 1 as the center;

[0043] The rotating adsorption string 7 includes a rotating motor, a rotating shaft 10, and a plurality of adsorption disks 11 on the rotating shaft 10. The rotating motor is arranged at the top outside the main tower 1. The rotating shaft 10 penetrates the main tower 1 and vertically passes through the outer adsorption area. The adsorption disk 11 penetrates the rotating shaft 10 through a through hole in its center, and is used to rotate horizontally with the rotating shaft 10.

[0044] A circle of first conveyor belt 13 is provided below the rotating shaft 10 . The first conveyor belt 13 corresponds to the bottom of a plurality of rotating adsorption strings 7 . The adsorption plate 11 moves downward along the rotating shaft 10 , falls on the first conveyor belt 13 , and then moves to the shielding adsorption string 8 .

[0045] Further optionally, external threads are evenly arranged on the outer surface of the rotating shaft 10, and internal threads matching the external threads are arranged on the inner surface of the through hole of the adsorption plate 11, so that the rotation direction of the rotating shaft and the adsorption plate is the same, and the adsorption plate can not only rotate with the rotating shaft, but also rotate downward along the rotating shaft.

[0046] Further optionally, the shape of the first conveyor belt 13 is the same as the shape surrounded by all the rotating shafts 10 in the outer adsorption area, and when the adsorption disk 11 on the rotating shaft 10 moves down to the bottom end of the rotating shaft 10, it will fall onto the first conveyor belt 13 if it continues to move down;

[0047] The first conveyor belt 13 is provided with a plurality of positioning rods 15 that can be extended and retracted up and down and moved left and right. The bottom of the positioning rods 15 is connected to a displacement controller for controlling the up and down and left and right movement of the positioning rods 15. The displacement controller can be arranged inside or below the first conveyor belt 13. The upper surface of the first conveyor belt 13 has a hollow area that cooperates with the movement of the positioning rods 15.

[0048] A positioning rod 15 is vertically arranged and corresponds to a rotating shaft 10 . The central through hole of the adsorption disk 11 dropped from the corresponding rotating shaft 10 can be passed through by the positioning rod 15 and then move to the shielding adsorption string 8 following the positioning rod 15 .

[0049] Further optionally, the adsorption disk 11 is a flat cylindrical shape, similar to a flat disk shape, and the adsorption disk 11 is formed by splicing a plurality of fan-shaped grids 16, each fan-shaped grid 16 is evenly provided with a plurality of sub-regions, and a proper amount of adsorption material is filled in each sub-region, so that the adsorption material is evenly distributed in the adsorption disk 11;

[0050] The adsorption disk 11 is kept horizontal on the rotating adsorption string 7, and the adsorption disk 11 is vertically hung on the shielding adsorption string 8, that is, the plane of the adsorption disk 11 with a larger surface area is vertically arranged.

[0051] When in use, the rotating shaft 10 of the rotating adsorption string 7 rotates continuously, thereby driving the adsorption disk 11 on the rotating shaft 10 to rotate, forming a certain degree of low pressure. The exhaust gas in the air intake area 4 on the side of the main tower 1 forms a radial flow under the guidance of the pressure difference, and can pass through the adsorption disk 11 in the outer adsorption area for adsorption. The external threads and rotation speeds of all rotating shafts 10 are the same, and each rotating shaft 10 has an adsorption disk 11 that can fall onto the first conveyor belt 13 at the same time. When the first conveyor belt 13 receives the adsorption disk 11, each positioning rod 15 is located below the side of the corresponding rotating shaft 10, and the positioning rod 15 protrudes from the upper surface of the first conveyor belt 13. The adsorption disk 11 falling from the bottom of the rotating shaft 10 has a certain rotation speed. After leaving the rotating shaft, it will continue to rotate and fall, thereby deviating from the rotating shaft in the vertical direction. According to the rotation speed of the rotating shaft and the adsorption disk, the position where the adsorption disk falls is calculated in advance, and a positioning rod is set at the center of the position so that the central through hole of the adsorption disk is just covered on the positioning rod 15.

[0052] Under the control of its own control device, the first conveyor belt 13 moves in a clockwise or counterclockwise direction, so that the positioning rod 15 rotates between the two rotating shafts 10, and the positioning rod 15 drives the adsorption disk to move along the radial inward adsorption zone of the main tower 1. Then, the positioning rod 15 shrinks and moves downward, so that the top of the positioning rod 15 is not higher than the upper surface of the first conveyor belt 13, preparing for the shielding adsorption string 8 to pick up the adsorption disk 11 on the first conveyor belt 13. The above action can transfer one adsorption disk 11 for each shielding adsorption string 8. The positioning rod 15 and the first conveyor belt 13 also have a reset function, that is, after each positioning rod 15 transfers one adsorption disk 11, the positioning rod 15 and the first conveyor belt 13 are reset to the initial position and state, ready to receive and transfer the next adsorption disk 11.

[0053] Optionally, the shielding adsorption string 8 includes a guide rail frame 17 and an adsorption plate 11, and the adsorption plate 11 is vertically hung on the guide rail frame 17 through a sliding hook 18 and can move from bottom to top along the guide rail frame 17;

[0054] The guide rail frame 17 is square, the vertical side inside the inner adsorption area is the first side, the vertical side outside the outer adsorption area is the second side, the horizontal side at the top of the guide rail frame is at the top of the adsorption area, and the horizontal side at the bottom of the guide rail frame is below the first conveyor belt 13, that is, the guide rail frame 17 frames the adsorption area;

[0055] The inner edge of the first conveyor belt 13 is close to the first side, which makes it easy for the sliding hook 18 of the guide rail frame 17 to pick up the adsorption plate 11 on the first conveyor belt 13; the outer side surface of the adsorption plate 11 is provided with a hollow circle protruding outward, and when the sliding hook 18 passes the inner edge of the first conveyor belt 13, it hooks the circle and then picks up the adsorption plate 11.

[0056] Further optionally, a second conveyor belt 14 is provided on the side of the top of each rotating shaft 10. The second conveyor belt 14 is horizontally arranged, with one end thereof close to the first side of the corresponding guide rail frame 17, and the other end close to the corresponding rotating shaft 10, for conveying the adsorption plate 11 moved up to the top of the guide rail frame 17 to the rotating shaft 10, thereby completing the cyclic movement of the adsorption plate 11 between the rotating adsorption string 7 and the shielding adsorption string 8.

[0057] Further optionally, the sliding hook 18 includes a base and a retractable hook, the base is slidably connected to the guide rail frame 17, the hook faces the direction of the rotating adsorption string 7, and the hook has a plurality of retractable hook sections, which are connected end to end when extended, and the hook section can be retracted into the base;

[0058] When the suction plate 11 needs to be picked up, part of the hook segments extend to form a common hook shape to hook the circle outside the suction plate 11; the other hook segments continue to extend until a circular hook is formed to prevent the suction plate 11 from being loosened from the hook when it rises along the guide rail frame 17;

[0059] When the suction plate 11 rises to the horizontal side of the guide rail frame 17 above the second conveyor belt 14 and moves toward the rotating shaft 10 along the horizontal side, the bottom of the suction plate 11 rests on the upper surface of the second conveyor belt 14, and the moving speed of the second conveyor belt 14 toward the rotating shaft 10 is greater than the moving speed of the sliding hook 18 on the horizontal side, so that the top of the suction plate 11 is tilted toward the shielding suction string 8. At this time, the hook section of the hook retracts back to the base, and the suction plate 11 loses the pulling force of the sliding hook 18 and is flat on the second conveyor belt 14.

[0060] Further optionally, on the shielding adsorption string 8, a positioning slider 19 is correspondingly arranged below each sliding hook 18, and the positioning slider 19 moves along the guide rail frame 17. A locking component 20 is arranged on the outer side of the positioning slider 19 (i.e., the side facing the rotating adsorption string 7). After the two locking pieces of the locking component 20 contact the adsorption disk 11, they automatically gather together to lock or clamp the frame mesh of the adsorption disk 11 to prevent the adsorption disk 11 from shaking on the guide rail frame 17; preferably, the locking component 20 corresponds to the center of the adsorption disk 11;

[0061] When the suction plate 11 needs to be separated from the guide rail frame 17, the clamping pieces of the locking component 20 automatically move away from each other to release the suction plate 11. An electromagnetic control device is arranged in the positioning slide block to connect and control the action of the locking component.

[0062] The adsorption disk 11 of the present invention can descend along the rotating shaft 10 in the outer adsorption area, move to the inner adsorption area through the first conveyor belt 13, then move upward along the shielding adsorption string 8, and then move to the rotating shaft 10 through the second conveyor belt 14, forming a circular movement, so that the adsorption disk 11 in the adsorption area is in continuous movement, the use of the adsorption material is relatively uniform, and there will be no phenomenon that some adsorption materials are saturated with adsorption first and other parts of the adsorption materials are saturated with adsorption later.

[0063] The adsorption plate 11 is horizontally arranged in the outer adsorption zone, and the exhaust gas coming in from the air intake zone 4 is inclined upward, and can pass through each adsorption plate 11 in the outer adsorption zone with less resistance. As the rotating adsorption string 7 rotates continuously, the pressure difference will form a passage between two adjacent rotating adsorption strings 7, and most or part of the intake air will enter the inner adsorption zone along the passage. The shielded adsorption string 8 corresponds to the position between the two rotating adsorption strings 7. The gas entering the inner adsorption zone will be blocked by the vertically mounted adsorption plate 11 moving on the shielded adsorption string 8, and adsorbed, thereby extending the residence time of the gas in the adsorption zone and improving the adsorption effect. After passing through the shielded adsorption string 8, the produced gas is obtained and enters the gas outlet zone 5, and then discharged from the main tower 1.

[0064] The installation position of the square rail frame 17 actually corresponds to the position between two adjacent rotating adsorption strings 7. A sliding hook 18 and a positioning slider 19 form a group, and move at the same speed, respectively hooking the top edge of the adsorption plate 11 and holding the middle of the adsorption plate 11 to stabilize the adsorption plate 11 and prevent it from being shaken left and right by the exhaust gas. All sliding hooks 18 and positioning sliders 19 move cyclically along the rail frame 17.

[0065] As described above, the suction plate 11 is pulled to the inner edge of the first conveyor belt 13 by the positioning rod, so that the hollow circle on the outer side of the suction plate 11 protrudes or partially protrudes from the inner edge of the first conveyor belt 13. After the positioning rod 15 is retracted and moved down to the position, when the sliding hook 18 moves to the front of the first conveyor belt 13, part of the hook section of the hook extends to form the shape of a common hook. As the sliding hook 18 moves upward, the hook hooks the circle on the outer side of the suction plate 11, and the suction plate 11 is gradually pulled up and dragged toward the guide rail frame 17; when the suction plate 11 is completely separated from the first conveyor belt 13, it will swing toward the guide rail frame 17 with the hook as the center, and after colliding with the guide rail frame 17, the locking component 20 locks or jams the frame mesh of the suction plate 11 to fix the position of the suction plate 11. Then, the suction plate 11 moves upward along the guide rail frame 17 with the corresponding sliding hook 18 and the positioning slider 19, and the sliding hook 18 below hooks up the subsequent suction plate 11.

[0066] The moving speed of each sliding hook 18 can be set individually. According to the downward moving speed of the adsorption plate 11 on the rotating shaft 10, the speed of the sliding hook 18 and the positioning slider 19 can be reasonably adjusted so that the adsorption plate 11 is not accumulated on the first conveyor belt 13, and the spacing between the upper and lower adjacent adsorption plates 11 of the shielding adsorption string 8 is reasonable.

[0067] When the sliding hook 18 and the positioning slider 19 drive the adsorption plate 11 to rise to the horizontal side of the guide rail frame 17 above the second conveyor belt 14, the locking component 20 opens, and the bottom of the adsorption plate 11 is placed on the upper surface of the second conveyor belt 14. As described above, the adsorption plate 11 is laid flat on the second conveyor belt 14 again. The sliding hook 18 and the positioning slider 19 that have removed the adsorption plate 11 continue to move along the second side of the guide rail frame 17, ready to pick up the adsorption plate 11 again. After the above series of movements, the adsorption plate 11 can loosen and adjust the adsorption material inside to achieve a good natural stacking state.

[0068] In order to cooperate with the adsorption disk 11 on the second conveyor belt 14 to install the rotating shaft 10, further optionally, a hinged component 22 is provided between two adjacent fan-shaped grids 16 on one side of the adsorption disk 11, and a spring switch 23 is provided on the other side of the adsorption disk 11 (i.e., the opposite side of the hinged component 22). When the spring switch 23 is turned on, the adsorption disk is divided into two semicircles;

[0069] The hollow circle on the outer side of the adsorption disk 11 is disconnected at the position corresponding to the spring switch, and a connecting rod 21 is provided at the position corresponding to the hinge part 22, and the two ends of the connecting rod 21 are respectively connected to the outer side of the adsorption disk and the circle, which not only stabilizes the position of the circle, but also facilitates marking the positions of the hinge part 22 and the spring switch 23; the circle is disconnected at the position corresponding to the hinge part, and the disconnection is arranged one above and one below, so as to avoid mutual squeezing of the disconnection of the circle of the corresponding hinge part after the spring switch is turned on;

[0070] A rotating component is provided inside the positioning slider 19, and the rotating component is rotatably connected to the locking component 20, and can control the locking component 20 to rotate, so as to adjust the position of the adsorption disk 11 hung on the sliding hook, so that the spring switch 23 of the adsorption disk 11 placed on the second conveyor belt 14 faces the rotating shaft 10. After the spring switch 23 is turned on, the opening of the adsorption disk 11 faces the rotating shaft 10;

[0071] A second conveyor belt 14 and an auxiliary installation belt 3 are respectively provided on both sides of the rotating shaft 10. The auxiliary installation belt 3 is provided on the opposite side of the second conveyor belt 14. The upper surfaces of the auxiliary installation belt 3 and the second conveyor belt 14 are flush. Two baffles 12 are provided on the upper surface of the auxiliary installation belt 3. The spacing between the ends of the two baffles close to the rotating shaft 10 is greater than the spacing between the ends away from the rotating shaft 10. After the opening side of the suction disc 11 crosses the rotating shaft 10, it is supported by the auxiliary installation belt 3. The auxiliary installation belt 3 is fixed and does not rotate. The suction disc moves toward the rotating shaft driven by the second conveyor belt 14. The opening side is closed during the movement along the two baffles 12, so that the suction disc is installed on the rotating shaft 10.

[0072] The auxiliary installation belt 3 and the second conveyor belt 14 are respectively moved a certain distance away from the rotating shaft 10, so that the newly installed suction plate 11 can be separated from the auxiliary installation belt 3 and the second conveyor belt 14 and move downward, and then the auxiliary installation belt 3 and the second conveyor belt 14 are reset to prepare for the installation of the next suction plate 11.

[0073] After the suction disc 11 rotates and falls on the first conveyor belt 13, the sliding hook 18 hooks any position of the outer circle of the suction disc 11 to lift the suction disc 11, and the locking component 20 fixes the center position of the suction disc 11. The locking component 20 drives the suction disc 11 to rotate, and the circle also rotates on the hook until the hook hits the connecting rod 21 on the circle and is stuck and cannot continue to rotate. The locking component 20 stops rotating at the same time. At this time, the hinged component 22 of the suction disc 11 corresponds to the sliding hook 18, and the spring switch 23 is at the bottom; when the suction disc 11 falls on the second conveyor belt 14, the spring switch 23 first falls on the second conveyor belt 14 and corresponds to the direction of the rotating shaft 10.

[0074] When a plurality of fan-shaped grids 16 are assembled into a suction plate 11, they are divided into two halves, and a spring switch 23 and a hinged component are installed on both sides of the suction plate 11. When the spring switch 23 is turned on, the two halves of the suction plate 11 are ejected away from each other to form an opening. The opened suction plate 11 moves toward the rotating shaft 10 on the second conveyor belt 14, and the rotating shaft 10 enters through the opening of the suction plate 11 and gradually moves to the center of the suction plate 11. Then, the opening part of the suction plate 11 is received by the auxiliary installation belt 3, and then the suction plate 11 is closed in the above manner, thereby being installed on the rotating shaft 10.

[0075] In the present invention, the spacing between adjacent rotating adsorption strings is small, so as not to affect the rotation of the adsorption disk. The spacing between adjacent shielding adsorption strings is also small, so as not to affect the adsorption disks. Since the adsorption disks have the same diameter, the rotating adsorption strings and the shielding adsorption strings are arranged alternately, and the flow path of the exhaust gas in the adsorption zone can be covered in the circumferential direction of the adsorption tower. In this way, a small amount of exhaust gas escaping from the gap between adjacent rotating adsorption strings will encounter the adsorption disk of the shielding adsorption string on the path flowing to the gas outlet zone, and thus be adsorbed on the shielding adsorption string. The gap between the adjacent shielding adsorption strings faces the rotating adsorption string, and the exhaust gas can be adsorbed by the rotating adsorption string first.

[0076] Although there is a small gap between adjacent adsorption plates on the rotating adsorption string and the shielding adsorption string, the adsorption plates on the two adsorption strings are constantly moving. When the exhaust gas passes through the adsorption area, it passes between the two adsorption plates of the rotating adsorption string. Since the adsorption plates are constantly moving downward, the horizontal airflow will always pass through a part of the adsorption plate. The gas passing through the rotating adsorption string and the gas escaping from between the rotating adsorption strings are intercepted by the shielding adsorption string and adsorbed again. In this way, all the exhaust gas can be adsorbed. Optionally, a circle of annular air baffles is provided above the second conveyor belt. The air baffle is concentrically arranged with the main tower. The outer side of the air baffle is fixedly connected to the inner wall of the main tower, and the inner side of the air baffle points to the center of the main tower. The area of ​​the vacant space in the center of the air baffle is not greater than the cross-sectional area of ​​the exhaust zone, so that the air baffle can block the small amount of exhaust gas rising to the top of the main body in the air inlet zone, so that most of the exhaust gas passes through the rotating adsorption string and the shielding adsorption string into the exhaust zone. Through holes are provided on the air baffle corresponding to the position of each rotating shaft, which does not affect the rotation of the rotating shaft.
